httpd实现http简单功能

<Directory "/var/www/html">
    Options None
    AllowOverride None
    AuthType Basic
    AuthName "String"
    AuthUserFile "/etc/httpd/conf/.httpdpasswd"
    AuthGroupFile "/etc/httpd/conf/.grp"
<RequireAll>
   Require ip 172.20
   Require user ops1
</RequireAll>
</Directory>

<Directory "/var/www/html">
Options None
AllowOverride None
AuthType Basic
AuthName "String"
AuthUserFile "/etc/httpd/conf/.httpdpasswd"
AuthGroupFile "/etc/httpd/conf/.grp"
<RequireAll>
   Require ip 172.20
   Require  group ops
</RequireAll>
</Directory>

(2)提供账号和密码存储（文本文件）
使用专用命令完成此类文件的创建及用户管理

htpasswd  [options]   /PATH/TO/HTTPD_PASSWD_FILE  username 
    -c：自动创建此处指定的文件，因此，仅应该在此文件不存在时使用；
    -m：md5格式加密
    -s: sha格式加密
    -D：删除指定用户
    -b：批模式添加用户

[[email protected] conf]# htpasswd -bc  /etc/httpd/conf/.httppasswd ops1 123456
Adding password for user ops1
[[email protected] conf]# vim /etc/httpd/conf/.grp
ops:ops1 ops2

(3)重启测试:
[[email protected] conf.d]# systemctl restart httpd

2.虚拟主机的配置
(1)基于IP地址的虚拟主机

[[email protected] /]# mkdir /data/html/{a,b} -pv
mkdir: created directory ‘/data/html’
mkdir: created directory ‘/data/html/a’
mkdir: created directory ‘/data/html/b’
[[email protected] /]# vim /data/html/a/index.html
<h1>hello a</h1>
[[email protected] /]# vim /data/html/b/index.html
<h1>hello b</h1>
[[email protected] conf.d]# vim vhost_ip.conf 
<VirtualHost 172.20.10.4:80>
    ServerName www.a.com
    DocumentRoot "/data/html/a/"
    <Directory "/data/html/a/">
        Options None
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>
<VirtualHost 172.20.10.7:80>
    ServerName www.b.com
    DocumentRoot "/data/html/b/"
    <Directory "/data/html/b/">
        Options None
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

(2)基于端口的虚拟主机:

[[email protected] conf.d]# vim vhost_ip.conf 
Listen 8080
<VirtualHost 172.20.10.4:80>
    ServerName www.a.com
    DocumentRoot "/data/html/a/"
    <Directory "/data/html/a/">
        Options None
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>
<VirtualHost 172.20.10.4:8080>
    ServerName www.b.com
    DocumentRoot "/data/html/b/"
    <Directory "/data/html/b/">
        Options None
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

(3)基于FQDN的虚拟主机:

[[email protected] conf.d]# vim vhost_ip.conf 
<VirtualHost 172.20.10.4:80>
    ServerName www.a.com
    DocumentRoot "/data/html/a/"
    <Directory "/data/html/a/">
        Options None
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>
<VirtualHost 172.20.10.4:80>
    ServerName www.b.com
    DocumentRoot "/data/html/b/"
    <Directory "/data/html/b/">
        Options None
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

注意：如果是httpd-2.2，则使用基于FQDN的虚拟主机时，需要事先使用如下指令：NameVirtualHost IP:PORT

3.实现https
[[email protected] conf.d]# yum install -y mod_ssl
(1)构建私有CA:

生成私钥；
~]# (umask 077; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096)
生成自签证书；
~]# openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 3655
-new：生成新证书签署请求；
-x509：生成自签格式证书，专用于创建私有CA时；
-key：生成请求时用到的私有文件路径；
-out：生成的请求文件路径；如果自签操作将直接生成签署过的证书；
-days：证书的有效时长，单位是day；
为CA提供所需的目录及文件；
~]# mkdir  -pv  /etc/pki/CA/{certs,crl,newcerts}
~]# touch  /etc/pki/CA/{serial,index.txt}
~]# echo  01 > /etc/pki/CA/serial

(2)要用到证书进行安全通信的服务器，需要向CA请求签署证书

用到证书的主机生成私钥；
~]# mkdir  /etc/httpd/ssl 
~]# cd  /etc/httpd/ssl
~]# (umask  077; openssl  genrsa -out  /etc/httpd/ssl/httpd.key  2048)
生成证书签署请求
~]# openssl  req  -new  -key  /etc/httpd/ssl/httpd.key  -out /etc/httpd/ssl/httpd.csr  -days  365
在CA主机上签署证书；
~]# openssl ca  -in  /etc/httpd/ssl/httpd.csr  -out  /etc/pki/CA/certs/httpd.crt  -days  365

[[email protected] /]# vim /etc/httpd/conf.d/ssl.conf 
DocumentRoot "/data/html/b/"
ServerName www.b.com:443
SSLCertificateFile /etc/httpd/ssl/httpd.csr
SSLCertificateKeyFile /etc/httpd/ssl/httpd.key
<Directory "/data/html/b/">
    Options None
    AllowOverride None
    Require all granted
</Directory>
