WAF嵌入LNMP集群架构

前言：

之前想着每天都更新一篇文章，但是连续几天之后，发现有好多博客大佬，所以觉得还是不要献丑好一点，然后就学习一下关于安全防护的知识，毕竟安全意识强弱代表在互联网防护能力，类似ddos，xss,csrf等也是经常出现，比如一些基本的×××方式：SQL注入，web参数，cc。所以我就记录了下面全程的将WAF嵌入LNMP架构，应用于实战集群架构。附带lua语言写的防护模块。

实战：

服务器架构图如下：

一、web服务器集群高可用负载均衡

1.高可用使用：nginx+keepalived模式

master（web1） 192.168.0.230slaver（web2） 192.168.0.211VIP：192.168.0.100

2.两边安装keepalived[root@web1 ~]# yum install -y keepalived

3.创建服务器监控脚本

[root@web1 ~]# mkdir -p /server/work [root@web1 ~]# cd /server/work/ [root@web1 work]# vim check_ng.sh #!/bin/bash #write by leo d=`date --date today +%Y%m%d_%H:%M:%S` n=`ps -C nginx --no-heading|wc -l` #如果进程为0，则启动nginx，并且再次检测nginx进程数量， #如果还为0，说明nginx无法启动，此时需要关闭keepalived if [ $n -eq "0" ]; then /etc/init.d/nginx start n2=`ps -C nginx --no-heading|wc -l` if [ $n2 -eq "0" ]; then echo "$d nginx down,keepalived will stop" >> /server/logs/nginx/check_ng.log systemctl stop keepalived fi fi [root@web1 work]# mkdir -p /server/logs/nginx [root@web1 work]# chmod +x check_ng.sh

4.修改master的keepalived配置文件

[root@web1 ~]# vim /etc/keepalived/keepalived.conf ! Configuration File for keepalived global_defs { notification_email { boheng@buyercamp.com } notification_email_from root@web1 smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id LVS_DEVEL } vrrp_script chk_nginx { script "/server/work/check_ng.sh" interval 3 } vrrp_instance VI_1 { state MASTER interface ens33 virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 000000 } virtual_ipaddress { 192.168.0.100 } track_script { chk_nginx } } [root@web1 ~]# systemctl stop nginx [root@web1 ~]# systemctl status nginx ● nginx.service - LSB: starts the nginx web server Loaded: loaded (/etc/rc.d/init.d/nginx; bad; vendor preset: disabled) Active: inactive (dead) Docs: man:systemd-sysv-generator(8) [root@web1 ~]# systemctl start keepalived [root@web1 ~]# systemctl status keepalived ● keepalived.service - LVS and VRRP High Availability Monitor Loaded: loaded (/usr/lib/systemd/system/keepalived.service; disabled; vendor preset: disabled) Active: active (running) since Fri 2018-07-13 15:06:13 CST; 32s ago Process: 14019 ExecStart=/usr/sbin/keepalived $KEEPALIVED_OPTIONS (code=exited, status=0/SUCCESS) Main PID: 14020 (keepalived) CGroup: /system.slice/keepalived.service ├─14020 /usr/sbin/keepalived -D ├─14021 /usr/sbin/keepalived -D └─14022 /usr/sbin/keepalived -D Jul 13 15:06:15 web1 Keepalived_vrrp[14022]: Sending gratuitous ARP on...

6.在master上查看IP地址

[root@web1 ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:c5:33:97 brd ff:ff:ff:ff:ff:ff inet 192.168.0.230/24 brd 192.168.0.255 scope global noprefixroute dynamic ens33 valid_lft 6103sec preferred_lft 6103sec inet 192.168.0.100/32 scope global ens33 valid_lft forever preferred_lft forever

7.在slaver上查看IP地址

[root@web2 ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:d7:df:dc brd ff:ff:ff:ff:ff:ff inet 192.168.0.211/24 brd 192.168.0.255 scope global noprefixroute dynamic ens33 valid_lft 6107sec preferred_lft 6107sec inet6 fe80::20c:29ff:fed7:dfdc/64 scope link valid_lft forever preferred_lft forever

8.在master上关闭keepalived服务（模拟master宕机或者脑裂情况）

[root@web1 ~]# systemctl stop keepalived [root@web1 ~]# systemctl status keepalived ● keepalived.service - LVS and VRRP High Availability Monitor Loaded: loaded (/usr/lib/systemd/system/keepalived.service; disabled; vendor preset: disabled) Active: inactive (dead) Jul 13 15:06:20 web1 Keepalived_vrrp[14022]: Sending gratuitous ARP on...

Hint: Some lines were ellipsized, use -l to show in full.

9.在slaver上查看状态

[root@web2 ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:d7:df:dc brd ff:ff:ff:ff:ff:ff inet 192.168.0.211/24 brd 192.168.0.255 scope global noprefixroute dynamic ens33 valid_lft 5895sec preferred_lft 5895sec inet 192.168.0.100/32 scope global ens33 valid_lft forever preferred_lft forever inet6 fe80::20c:29ff:fed7:dfdc/64 scope link valid_lft forever preferred_lft forever [root@web2 ~]# systemctl status keepalived ● keepalived.service - LVS and VRRP High Availability Monitor Loaded: loaded (/usr/lib/systemd/system/keepalived.service; disabled; vendor preset: disabled) Active: active (running) since Fri 2018-07-13 15:07:20 CST; 7min ago Process: 13279 ExecStart=/usr/sbin/keepalived $KEEPALIVED_OPTIONS (code=exited, status=0/SUCCESS) Main PID: 13280 (keepalived) CGroup: /system.slice/keepalived.service ├─13280 /usr/sbin/keepalived -D ├─13281 /usr/sbin/keepalived -D └─13282 /usr/sbin/keepalived -D Jul 13 15:12:22 web2 Keepalived_vrrp[13282]: Sending gratuitous ARP on...

10.查看丢包情况在windows上模拟持续性访问，使用ping查看丢包情况

二、建立共享存储服务器

1.安装NFS方式，master 服务端[root@web1 web]# yum install -y rpcbind nfs-utils

2.slaver 客户端[root@web2 web]# yum install -y nfs-utils

3.master服务端启动共享存储服务

[root@web1 web]# cat /etc/exports /server/web 192.168.0.0/24(rw,sync,no_root_squash) [root@web1 web]# systemctl start nfs

4.slaver客户端查看共享存储

[root@web2 web]# showmount -e 192.168.0.230 Export list for 192.168.0.230: /server/web 192.168.0.0/24 [root@web2 web]# [root@web2 web]# mount -t nfs 192.168.0.230:/server/web /server/web -o proto=tcp -o nolock [root@web2 web]# ls [root@web2 web]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos-root 50G 4.2G 46G 9% / devtmpfs 899M 0 899M 0% /dev tmpfs 911M 0 911M 0% /dev/shm tmpfs 911M 9.6M 902M 2% /run tmpfs 911M 0 911M 0% /sys/fs/cgroup /dev/sda1 1014M 142M 873M 14% /boot /dev/mapper/centos-home 47G 74M 47G 1% /home tmpfs 183M 0 183M 0% /run/user/0 192.168.0.230:/server/web 50G 4.2G 46G 9% /server/web [root@web2 web]#

5.修改nginx配置文件（两边配置一致）

[root@web1 ~]# cd /usr/local/nginx/conf/vhost/ [root@web1 vhost]# vim zt.conf server { listen 80; #listen [::]:80 default_server ipv6only=on; server_name zt.linuxview.com ; index index.html index.htm index.php; root /server/web/test; #error_page 404 /404.html; error_page 404 404/404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~* ^/data/(attachment|avatar)/.*\.(php|php5)$ { deny all; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } location ~ /\. { deny all; } access_log /server/logs/nginx/zuitu/access.log ; error_log /server/logs/nginx/zuitu/error.log ; }

6.访问网页

7.master上设置反向代理

[root@web1 vhost]# vim xs.conf server { listen 80; server_name xs.linuxview.com ; location / { proxy_pass http://192.168.0.211:80; proxy_set_header Host xs.linuxview.com; proxy_redirect off; proxy_set_header X-Real-IP 192.168.0.211; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 60; proxy_read_timeout 600; proxy_send_timeout 600; } access_log /server/logs/nginx/zuitu/access.log ; error_log /server/logs/nginx/zuitu/error.log ; } [root@web1 vhost]# /usr/local/nginx/sbin/nginx -s reload

8.slaver上设置nginx的配置文件

[root@web2 vhost]# vim xs.conf server { listen 80; #listen [::]:80 default_server ipv6only=on; server_name xs.linuxview.com ; index index.html index.htm index.php; root /server/web/test3; #error_page 404 /404.html; error_page 404 404/404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~* ^/data/(attachment|avatar)/.*\.(php|php5)$ { deny all; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } location ~ /\. { deny all; } access_log /server/logs/nginx/zuitu/access.log ; error_log /server/logs/nginx/zuitu/error.log ; } [root@web2 vhost]# /usr/local/nginx/sbin/nginx -s reload

9.访问网页测试

三、WAF镶嵌lnmp架构

1.安装依赖包[root@waf ~]# yum install -y readline-devel pcre-devel openssl-devel gcc* git* libxml2*

2.下载2.0.5版本的luajit，编译安装

[root@waf ~]# mkdir -p /server/source [root@waf ~]# cd /server/source/ [root@waf source]# wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz [root@waf source]# tar -xf LuaJIT-2.0.5.tar.gz [root@waf source]# cd LuaJIT-2.0.5 [root@waf LuaJIT-2.0.5]# export LUAJIT_LIB=/user/local/lib [root@waf LuaJIT-2.0.5]# export LUAJIT_INC=/usr/local/include/luajit-2.0 [root@waf LuaJIT-2.0.5]# make && make install && ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2

成功安装标志：

3.下载并编译安装openresty

[root@waf source]# wget https://openresty.org/download/openresty-1.11.2.2.tar.gz [root@waf source]# tar -xf openresty-1.11.2.2.tar.gz [root@waf source]# cd openresty-1.11.2.2 [root@waf openresty-1.11.2.2]# ./configure --prefix=/usr/local/openresty --user=www --group=www --with-luajit --with-http_v2_module --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module --with-pcre --with-pcre-jit --with-file-aio --with-http_dav_module [root@waf openresty-1.11.2.2]# gmake && gmake install

4.修改最大文件打开数量

[root@waf openresty-1.11.2.2]# vim /proc/sys/fs/file-max 100000 [root@waf openresty-1.11.2.2]# ulimit -l 64

5.修改openresty内置的nginx配置文件（--prefix指定的是安装目录，所以配置文件就在安装目录里面，编译完成之后，就不用在源码包界面了）

[root@waf openresty]# mkdir /server/conf [root@waf openresty]# pwd /usr/local/openresty [root@waf openresty]# cd /server/conf/ [root@waf conf]# ls [root@waf conf]# ln -s /usr/local/openresty /server/conf/openresty [root@waf conf]# ls openresty [root@waf conf]# ln -s /usr/local/openresty/nginx /server/conf/nginx [root@waf conf]# ll total 0 lrwxrwxrwx 1 root root 26 Jul 10 09:25 nginx -> /usr/local/openresty/nginx lrwxrwxrwx 1 root root 20 Jul 10 09:23 openresty -> /usr/local/openresty [root@waf conf]#vim nginx.conf （修改user为www ,在最后一行的括号上新增include vhost/*.conf;） [root@waf conf]# useradd www -M -s /sbin/nologin [root@waf conf]# mkdir vhost [root@waf conf]# cd vhost/ ##编写测试网页 [root@waf vhost]# vim waf.conf server { listen 80 ; server_name waf.linuxview.com ; index index.html index.php index.htm ; root /server/web/waf ; error_log /server/logs/nginx/waf/error.log; access_log /server/logs/nginx/waf/access.log; } [root@waf vhost]# mkdir -p /server/web/waf && cd /server/web/waf ##创建测试网页 [root@waf waf]# cat index.html Welcome to Linuxview!!! ##重加载nginx [root@waf waf]# /usr/local/openresty/nginx/sbin/nginx -s reload

6.访问测试网页

7.安装waf防护模块

[root@waf waf]# cd /server/source/ #这个目录用来存源码或软件包等 [root@waf source]# git clone https://github.com/leoheng/lua.git #这些全是lua语言写的防护模块，复制到nginx的conf配置文件目录 [root@waf waf]# cp -a ./waf /server/conf/nginx/conf/ [root@waf waf]# cd /server/conf/nginx/conf/ [root@waf conf]# ls fastcgi.conf koi-win scgi_params waf fastcgi.conf.default mime.types scgi_params.default win-utf fastcgi_params mime.types.default uwsgi_params fastcgi_params.default nginx.conf uwsgi_params.default koi-utf nginx.conf.default vhost [root@waf conf]# cd waf/ [root@waf waf]# ls access.lua config.lua init.lua lib.lua rule-config [root@waf waf]#cd .. ##在http字段下添加lua模块 [root@waf conf]# vim nginx.conf lua_shared_dict limit 50m; ##CC,50M lua_package_path /server/conf/nginx/conf/waf/?.lua ; init_by_lua_file /server/conf/nginx/conf/waf/init.lua ; access_by_lua_file /server/conf/nginx/conf/waf/access.lua ; ##检查配置文件并重加载服务 [root@waf conf]# /usr/local/openresty/nginx/sbin/nginx -t nginx: the configuration file /usr/local/openresty/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/openresty/nginx/conf/nginx.conf test is successful [root@waf conf]# /usr/local/openresty/nginx/sbin/nginx -s reload

8.配置waf防护

[root@waf waf]# cat config.lua --WAF config file,enable = "on",disable = "off" ##WAF功能选项 --waf status config_waf_enable = "on" ##是否启动waf防护 --log dir config_log_dir = "/server/logs/waf_logs" ##waf的日志 --rule setting config_rule_dir = "/usr/local/openresty/nginx/conf/waf/rule-config" ##waf的防护规则配置文件 --enable/disable white url config_white_url_check = "on" ##配置白名单url检查 --enable/disable white ip config_white_ip_check = "on" ##配置白名单IP检查 --enable/disable block ip config_black_ip_check = "on" ##配置黑名单IP检查 --enable/disable url filtering config_url_check = "on" ##配置url检查过滤 --enalbe/disable url args filtering config_url_args_check = "on" ##配置url参数检查 --enable/disable user agent filtering config_user_agent_check = "on" ##配置用户代理检查 --enable/disable cookie deny filtering config_cookie_check = "on" ##配置cookie过滤检查 --enable/disable cc filtering config_cc_check = "on" ##配置CC×××检查过滤 --cc rate the xxx of xxx seconds config_cc_rate = "10/60" ##CC×××速率访问网页每60秒访问10次 --enable/disable post filtering config_post_check = "on" ##配置post检查过滤 --config waf output redirect/html config_waf_output = "html" ##配置匹配成功重定向或者输出警告页面 --if config_waf_output ,setting url config_waf_redirect_url = "https://www.baidu.com" ##重定向到百度首页 ##输出HTML格式的警告信息[[ html警告内容 ]] config_output_html=[[ <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta http-equiv="Content-Language" content="zh-cn" /> <title>WAF-TEST</title> </head> <body> <h1 align="center> WAF功能防护中，请勿进行非正常操作 </body> </html> ]]

9.访问匹配模块规则：检测白名单-》黑名单-》UA×××检测-》CC×××检测-》cookie检测-》URL检测-》URL×××检测-》URL参数检测-》post检测

[root@waf waf]# cat access.lua require 'init' ##先请求init.lua文件进行匹配，然后进行检查功能匹配 ##配置检查顺序 function waf_main() if white_ip_check() then elseif black_ip_check() then elseif user_agent_attack_check() then elseif cc_attack_check() then elseif cookie_attack_check() then elseif white_url_check() then elseif url_attack_check() then elseif url_args_attack_check() then --elseif post_attack_check() then else return end end waf_main() [root@waf waf]#

10.防护规则大概流程图：

11.url参数测试

12.模拟CC×××测试[root@waf waf]# ab -c 100 -t 100 http://waf.linuxview.com/

13.查看日志记录：×××方式，客户端地址，被×××的服务器时间等等

14.SQL测试

15.安装httpguard再升级CC防护下载压缩包，复制lua配置到waf下

[root@waf waf]# cd /server/source/ [root@waf source]# wget --no-check-certificate https://github.com/centos-bz/HttpGuard/archive/master.zip [root@waf source]# unzip master.zip [root@waf source]# cd HttpGuard-master/ [root@waf HttpGuard-master]# cp guard.lua /server/conf/nginx/conf/waf/ [root@waf HttpGuard-master]# cp runtime.lua /server/conf/nginx/conf/waf/

四、MySQL5.7集群（双主多从模式）

当只有两台数据库的时候，使用双主模式（互为主从）

1.修改master的mysql配置文件

[root@web1 ~]# vim /etc/my.cnf #在mysqld下新增一下配置 [mysqld] log-bin=mysql-bin binlog_format=mixed server-id = 1 sync_binlog = 1 binlog_checksum = none binlog_format = mixed auto-increment-increment = 2 auto-increment-offset = 1 slave-skip-errors = all [root@web1 ~]# systemctl restart mysql [root@web1 ~]# systemctl status mysql ● mysql.service - LSB: start and stop MySQL Loaded: loaded (/etc/rc.d/init.d/mysql; bad; vendor preset: disabled) Active: active (exited) since Fri 2018-07-13 17:18:39 CST; 6s ago Docs: man:systemd-sysv-generator(8) Process: 37255 ExecStart=/etc/rc.d/init.d/mysql start (code=exited, status=0/SUCCESS) Jul 13 17:18:39 web1 systemd[1]: Starting LSB: start and stop MySQL... Jul 13 17:18:39 web1 mysql[37255]: Starting MySQL SUCCESS! Jul 13 17:18:39 web1 systemd[1]: Started LSB: start and stop MySQL.

2.进入数据库，赋权给web2用户，让它连接主数据库同步数据

[root@web1 ~]# mysql -uroot -p000000 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.18-log Source distribution Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> grant replication slave,replication client on *.* to web2@'192.168.0.%' identified by "000000"; Query OK, 0 rows affected, 1 warning (0.13 sec) mysql> flush privileges; Query OK, 0 rows affected (0.03 sec) ###查看log bin日志和post值位置 mysql> show master status; +------------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+------------------+-------------------+ | mysql-bin.000006 | 620 | | | | +------------------+----------+--------------+------------------+-------------------+ 1 row in set (0.01 sec) mysql>

3.在slaver上修改MySQL配置文件

[root@web2 ~]# vim /etc/my.cnf [mysqld] server-id = 2 log-bin = mysql-bin sync_binlog = 1 binlog_checksum = none binlog_format = mixed auto-increment-increment = 2 auto-increment-offset = 2 slave-skip-errors = all [root@web2 ~]# systemctl restart mysql [root@web2 ~]# systemctl status mysql ● mysql.service - LSB: start and stop MySQL Loaded: loaded (/etc/rc.d/init.d/mysql; bad; vendor preset: disabled) Active: active (running) since Fri 2018-07-13 17:29:56 CST; 20s ago Docs: man:systemd-sysv-generator(8) Process: 31883 ExecStart=/etc/rc.d/init.d/mysql start (code=exited, status=0/SUCCESS) CGroup: /system.slice/mysql.service ├─31891 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/m... └─32461 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadi...

Jul 13 17:29:56 web2 systemd[1]: Started LSB: start and stop MySQL.

4.创建数据库用户用于数据库同步数据

[root@web2 ~]# mysql -uroot -p000000 mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.7.18-log Source distribution Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> grant replication slave,replication client on *.* to web2@'192.168.0.%' identified by "000000"; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'identiified by "000000"' at line 1 mysql> grant replication slave,replication client on *.* to web2@'192.168.0..%' identified by "000000"; Query OK, 0 rows affected, 1 warning (0.18 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> show master status; +------------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+------------------+-------------------+ | mysql-bin.000007 | 610 | | | | +------------------+----------+--------------+------------------+-------------------+ 1 row in set (0.01 sec) mysql>

5.在master上同步数据库到slaver上

mysql> stop slave; Query OK, 0 rows affected, 1 warning (0.02 sec) mysql> change master to master_host='192.168.0.211',master_user='web2',master_password='000000',master_log_file='mysql-bin.000006',master_log_pos=620; Query OK, 0 rows affected, 2 warnings (0.03 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status \G; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.0.211 Master_User: web2 Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000008 Read_Master_Log_Pos: 1110 Relay_Log_File: web1-relay-bin.000002 Relay_Log_Pos: 312 Relay_Master_Log_File: mysql-bin.000008 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 1110 Relay_Log_Space: 510 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 2 Master_UUID: ed87ba4b-8653-11e8-94fe-000c29d7dfdc Master_Info_File: /usr/local/mysql/var/master.info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has read all relay log; waiting for more updates Master_Retry_Count: 86400 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: Executed_Gtid_Set: Auto_Position: 0 Replicate_Rewrite_DB: Channel_Name: Master_TLS_Version: 1 row in set (0.00 sec)

6.在slaver上同步master的数据库

mysql> stop slave; Query OK, 0 rows affected, 1 warning (0.02 sec) mysql> change master to master_host='192.168.0.230',master_user='web2',master_password='000000',master_log_file='mysql-bin.000006',master_log_pos=620; Query OK, 0 rows affected, 2 warnings (0.03 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status \G; *************************** 1. row *************************** Slave_IO_State: Connecting to master Master_Host: 192.168.0.230 Master_User: web1 Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000010 Read_Master_Log_Pos: 1110 Relay_Log_File: web2-relay-bin.000001 Relay_Log_Pos: 4 Relay_Master_Log_File: mysql-bin.000010 Slave_IO_Running: Yes Slave_SQL_Running: Yes

7.在master的数据库上创建数据库和表

mysql> create database leotest; Query OK, 1 row affected (0.00 sec) mysql> use leotest; Database changed mysql> create table test(id int(4),name varchar(10)); Query OK, 0 rows affected (0.04 sec) mysql> show tables ; +-------------------+ | Tables_in_leotest | +-------------------+ | test | +-------------------+ 1 row in set (0.00 sec) mysql>

8.在slaver上查看同步的数据

mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | leotest | | mysql | | performance_schema | | sys | +--------------------+ 5 rows in set (0.00 sec) mysql>

至此，MySQL集群已完成，而waf嵌入LNMP集群架构也完成了。
