linux学习->GRID+ASM+DB(单机环境)

来源:互联网 收集:自由互联 发布时间:2022-05-30
修改主机名: vi /etc/hostname 修改hosts: vi /etc/hosts 添加 192.168.2.130 ORCL 修改network网络文件: vi /etc/sysconfig/network 添加 NETWORKING=yes 添加与hosts对应的主机名 HOSTNAME=ORCL cat/etc/sysconfig/network E

修改主机名:

  vi  /etc/hostname

 

修改hosts:

  vi  /etc/hosts

添加  192.168.2.130  ORCL

 

修改network网络文件:

  vi  /etc/sysconfig/network

添加  NETWORKING=yes

添加与hosts对应的主机名  HOSTNAME=ORCL

cat>>/etc/sysconfig/network<<EOF
NETWORKING=yes
HOSTNAME=ORCL
EOF

 

 

修改ifcfg-ens33网卡配置文件:

  vi /etc/sysconfig/network-scripts/ifcfg-ens33

修改: BOOTPROTO="dhcp"   =>BOOTPROTO="static"

添加: IPADDR="192.168.2.130"

添加:GATEWAY="192.168.2.1"

添加: NETMASK="255.255.255.0"

 

重启网络服务:

  service network restart

 

挂载新目录:
  查看机器所挂硬盘个数及分区情况:fdisk -l  (只有/dev/sda,没有/dev/sdb)

  添加硬盘(默认):内存自选(刚学习时老师选择了80G)。

  重启:reboot

  查看机器所挂硬盘个数及分区情况:fdisk -l  (有/dev/sdb)

  挂载光盘:(未选择光盘时查看/dev/cdrom也存在sr0,但是不能挂载,暂时不理解)

    (1)虚拟机=>设置=>CD/DVD(SATA)         

        i.勾选上已连接

        ii. 选择使用ISO映像文件=>选定iso文件

    (2)df -h查看磁盘占用情况(没有这一行  /dev/sr0     3.6G   3.6G  0  100%  /mnt)

    (3)手动挂载光盘:

        mount  /dev/cdrom  /mnt/

    (4)df -h查看磁盘占用情况(此时显示有  /dev/sr0     3.6G   3.6G  0  100%  /mnt)

  格式化磁盘(/dev/sdb):

    (1)fdisk  /dev/sdb      (m查看帮助)

        i.n  (add a new partiton)

        ii.回车  select(default p)

        iii.回车  Partition number(1-4,default 1)

        iv.回车  First sector(2048-167772159,default 2048)

        v.回车  Last sector...

    (2)写入磁盘并退出

        i.w  (write table to disk and exit)

    (3)查看机器所挂硬盘个数及分区情况 fdisk -l   (显示出/dev/sdb1  这行)

    (4)将物理硬盘分区初始化为物理卷

        pvcreate  /dev/sdb1

    (5)创建vg

        vgcreate  u01_vg  /dev/sdb1

    (6)分配卷组

        lvcreate  -l  +100%FREE  -n  u01_lv  u01_vg

     (7)格式化逻辑卷

        mkfs.ext4  /dev/u01_vg/u01_lv

    (8)挂载磁盘(不明白这个挂载是干嘛的)

        mkdir  /u01

        mount  /dev/u01_vg/u01_lv  /u01/

        df  -h  (此时可以看到/dev/mapper/u01_vg-u01_lv  79G  57M  75G  1%  /u01)

        (此时重启不会自动挂载)

    (9)设置分区在系统重启后自动挂载

        vi  /etc/fstab

        添加 /dev/u01_vg/u01_lv  /u01  ext4  defaults  0  0

    (10)重启查看是否自动挂载

        reboot

        df -h

        此时可以看到(8)的显示了,但是光盘的(4)没有显示,这是因为磁盘自动挂载了,光盘没有。

        再次手动挂载一下光盘。

        mount  /dev/cdrom  /mnt/

        df -h查看磁盘占用情况(此时显示有  /dev/sr0     3.6G   3.6G  0  100%  /mnt)

        

  配置本地yum源

    (1)创建yum目录:mkdir  -p  /u01/soft/yum

    (2)切换工作目录:cd  /u01/soft/yum

    (3)拷贝/mnt/下的所有文件到此目录下:cp  -R  /mnt/*  ./

        另:开启另一终端可以用du  -sh查看当时内存占用,判断拷贝进度。

    (4)配置相关文件:vi  /etc/yum.repos.d/local.repo

      i.写入以下信息:

        

cat>>/etc/yum.repos.d/local.repo<<EOF

[base] name=linux 7 baseurl=file:///u01/soft/yum gpgcheck=0 enable=1

EOF

 

    (5)修改yum源地址

        vi  /usr/lib/python2.7/site-packages/yum/yumRepo.py

        修改:remote = url + '/' + relative  =>  remote = url + '/u01/soft/yum' + relative

        

    (6)清除原有缓存:yum  clean  all

    (7)重建缓存:yum  makecache

  

   安装图形界面:

    yum  list  (可列出所有可安装的包)

    yum  grouplist  (列出程序组)

    (1)安装图形界面程序组

        yum  -y  groupinstall  "Server with GUI"

    (2)开启图形界面

        startx

        

   创建OS属主、用户:

      (1)创建属主

groupadd -g 11001 oinstall
groupadd -g 11002 dba
groupadd -g 11003 oper
groupadd -g 11004 backupdba

groupadd -g 11007 asmdba
groupadd -g 11008 asmoper
groupadd -g 11009 asmadmin
groupadd -g 11010 racdba

    (2)创建用户

useradd -u 11011 -g oinstall -G dba,asmdba,backupdba,dgdba,kmdba,racdba,oper oracle
useradd -u 11012 -g oinstall -G asmadmin,asmdba,asmoper,dba,racdba grid
  #设置密码
passwd grid
passwd oracle

    (3)修改用户资源限制

        vi  /etc/security/limits.conf

        添加以下内容

grid   soft nproc   4096    
grid   hard nproc   16384    
grid   soft nofile   2047    
grid   hard nofile   65536    
grid   soft stack   10240    
grid   hard stack   32768    
       
oracle   soft nproc   4096    
oracle   hard nproc   16384    
oracle   soft nofile   1024    
oracle   hard nofile   65536    
oracle   soft stack   10240

grid   soft memlock   1073741824    
grid   hard memlock   1073741824    
oracle   soft memlock   1073741824    
oracle   hard memlock   1073741824    

    (4)创建相关目录

        

mkdir -p /u01/app/db/19.3
mkdir -p /u01/app/grid/crs
mkdir -p /u01/app/grid/19.3
chown -R grid:oinstall /u01
chmod -R 775 /u01/app
chown -R grid:oinstall /u01/app/grid
chown -R oracle:oinstall /u01/app/db
chmod -R 775 /u01/app/db
chmod -R 775 /u01/app/grid

    (5)设置环境变量

      grid用户    (env  |grep  ORA)

      i.切换到grid用户:su  -  grid

      ii.编辑环境变量:

cat>>~/.bash_profile<<EOF

ORACLE_SID=+ASM; export ORACLE_SID #ORACLE_TERM=xterm; export ORACLE_TERM ORACLE_BASE=/u01/app/grid/crs; export ORACLE_BASE ORACLE_HOME=/u01/app/grid/19.3; export ORACLE_HOME NLS_DATE_FORMAT="yyyy-mm-dd HH24:MI:SS"; export NLS_DATE_FORMAT PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

EOF

      iii.更新环境变量:source  ~/.bash_profile

      

      oracle用户

      i.切换到oracle用户:su  -  oracle

      ii.创建软件目录

mkdir -p /u01/app/db
mkdir -p /u01/app/db/product/19.3/db_1
chown -R oracle:oinstall /u01/app/db

      iii.编辑环境变更:

cat>>~/.bash_profile<<EOF

ORACLE_BASE=/u01/app/db; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/19.3/db_1; export ORACLE_HOME ORACLE_SID=TESTDB; export ORACLE_SID PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin; export PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib if [ $USER = "oracle" ] || [ $USER = "grid" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi umask 022 fi

EOF

     iv.更新环境变量:source  ~/.bash_profile

 

 

  解压安装介质:

    (1)拷贝LINUX.X64_193000_grid_home.zip,LINUX.X64_193000_db_home.zip到虚拟机中。

    (2)查找介质文件:find  /  -name  LINUX.X64_193000_grid_home.zip

    (3)移动介质文件到 /u01/soft/:mv ./*  /u01/soft

    (4)给予grid、oracle用户解压安装的权限:
        chown  -R  grid:oinstall  LINUX.X64_193000_grid_home.zip
        chown  -R  oracle:oinstall  LINUX.X64_193000_db_home.zip

    (5)切换到grid用户并移动到解压目录:

        su  -  grid

        cd  /u01/app/grid/19.3

    (6)将LINUX.X64_193000_grid_home.zip拷贝到解压目录:cp  /u01/soft/LINUX.X64_193000_grid_home.zip  ./

    (7)解压:unzip  LINUX.X64_193000_grid_home.zip

 

  GRID安装:检查校验环境

    su  -  grid

    cd  $ORACLE_HOME

    ./runcluvfy.sh  stage  -pre  crsinst  -n  tjy  -verbose  >  /home/grid/pre.log

    {root用户

      tail  -20f  /home/grid/pre.log

    }

    

    (root)系统参数文件配置:

      i.  添加以下内容

cat>>/etc/sysctl.conf<<EOF

vm.swappiness = 1 vm.dirty_background_ratio = 3 vm.dirty_ratio = 80 vm.dirty_expire_centisecs = 500 vm.dirty_writeback_centisecs = 100 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.panic_on_oops = 1 # net.ipv4.conf.ens33.rp_filter = 2 # net.ipv4.conf.ens34.rp_filter = 2

EOF

 

 

    ii.修改生效:sysctl  -p  /etc/sysctl.conf

  

  (root)文件限制:

    添加以下内容:

      

cat>>/etc/security/limits.d/99-grid-oracle-limits.conf<<EOF

oracle soft nproc 16384 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240 oracle hard stack 32768 grid soft nproc 16384 grid hard nproc 16384 grid soft nofile 1024 grid hard nofile 65536 grid soft stack 10240 grid hard stack 32768

EOF

 

  停止avahi-daemon服务

    systemctl disable avahi-daemon.socket

    systemctl disable avahi-daemon.service

 

  检验补丁包:

rpm -q  gcc-c++ bc binutils compat-libcap1 compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel fontconfig-devel glibc glibc-devel ksh libaio libaio-devel libX11 libXau libXi libXtst libXrender libXrender-devel libgcc libstdc++ libstdc++-devel libxcb make net-tools nfs-utils python python-configshell python-rtslib python-six targetcli smartmontools sysstat bc-1.06.95-13.el7.x86_64

 

    将 is not installed的补丁包安装:

      yum  install  targetcli(关联包选择y,一起安装)

      yum  install  libstdc++-devel

      yum  install  libXrender-devel

      yum  install  libaio-devel

      yum  install  fontconfig-devel

      yum  install  elfutils-libelf-devel

      #  yum  install  compat-libstdc++-33  (这个包没有,下一步补全)

      yum  install  compat-libcap1

      yum  install  gcc-c++

      yum  install  ksh

 

  

      补全上一步

        拷贝compat-libstdc++-33-3.2.3-69.el6.x86_64.rpm,compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm到虚拟机中。

      {

      (root用户)

        cd  /root/Downloads

        #  rpm  -ivh  compat-libstdc++-33-3.2.3-69.el6.x86_64.rpm

        rpm  -ivh  compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm

 

      

 

      cd  /u01/app/grid/19.3/cv/rpm

      rpm  -ivh  cvuqdisk-1.0.10-1.rpm

 

      }

      

 

  创建共享存储(创建ASM磁盘)

    虚拟机=>设置=>添加=>硬盘添加      全默认{文件名:asm_01.vmdk、asm_02.vmdk、asm_03.vmdk}

 

    init  0   (关机)

 

    修改虚拟机在主机的配置文件:

      路径(安装路径):G:\Virtual Machines\Red Hat Enterprise Linux 7 64 位.vmx

      添加以下内容

disk.locking = "FALSE"
disk.EnableUUID = "TRUE"
scsi1.sharedBus = "VIRTUAL"   
diskLib.dataCacheMaxSize = "0"
    //diskLib.dataCacheMaxReadAheadSize = "0"
    //diskLib.dataCacheMinReadAheadSize = "0"
    //diskLib.dataCachePageSize = "4096"
    //diskLib.maxUnsyncedWrites = "0"
scsi0:2.deviceType = "disk"
scsi0:3.deviceType = "disk"
scsi0:4.deviceType = "disk"
//老师讲课时有四行没有添加上,暂时保存下来

 

    保存后打开虚拟机:

    

    检验添加的三个磁盘:

/usr/lib/udev/scsi_id  -g  -u  -d  /dev/sdc

/usr/lib/udev/scsi_id  -g  -u  -d  /dev/sdd

/usr/lib/udev/scsi_id  -g  -u  -d  /dev/sde

 

    自动挂载ASM存储设备:

for i in c d e ;
do
echo "KERNEL==\"sd$i\", SUBSYSTEM==\"block\", PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d /dev/\$name\", RESULT==\"`/usr/lib/udev/scsi_id -g -u -d /dev/sd\$i`\", SYMLINK+=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""
done

    执行后输出信息:

KERNEL=="sdc", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c29a4d2c41378ffa17ba124b964f", SYMLINK+="asm-diskc", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sdd", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c299bd83f11a666056e3845e0ba4", SYMLINK+="asm-diskd", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sde", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$name", RESULT=="36000c293e55d1e0976ee481f5d72236f", SYMLINK+="asm-diske", OWNER="grid", GROUP="asmadmin", MODE="0660"

    编辑相关文件

      vi  /etc/udev/rules.d/99-oracle-asmdevices.rules

      拷贝上面输出的信息到该文件中。

    

 

    重启udev前不能看到asm存储设备:ls  -l  /dev/asm*  (没有东西)

 

    重启udev

      systemctl  restart  systemd-udev-trigger.service

      udevadm  control  --reload-rules

      udevadm  trigger

    

    重启后能看到asm存储设备:ls  -l  /dev/asm*

 

    关闭chrony服务:

      systemctl  stop  chronyd

      systemctl  disable  chronyd

      mv  /etc/chrony.conf  /etc/chrony.conf.bak

      systemctl  status  chronyd

    

    禁用NTP模式(单机,没有配置,出错很正常的啦):

      systemctl  disable  ntpd.service

      systemctl  stop  ntpd.service

      mv  /etc/ntp.conf  /etc/ntp.conf.bak

      systemctl  status  ntpd

 

    修改Selinux

      getenforce  //查看Selinux状态

      setenforce  0  //临时关闭Selinux

      vi  /etc/sysconfig/selinux  //编辑文件设置disabled

      修改:SELINUX=enforcing  =>  SELINUX=disabled

    

    停止avahi-daemon服务:

      systemctl  disable  avahi-daemon.socket

      systemctl  disable  avahi-daemon.service
