CentOS7.6搭建RAC
1.系统环境配置
1.1概述
搭建两个节点的rac集群，其每个节点均有两个网卡，public网卡和private网卡。两个节点的主机名分别为rac1和rac2
1.2 参数设置（RAC1&RAC2）
-
编辑/etc/hosts文件
vim /etc/hosts注释掉以下内容,
#127.0.0.1 localhost rac1 localhost4 localhost4.localdomain4 #::1 localhost rac1 localhost6 localhost6.localdomain6注：如果没有注释上述内容，在安装rac的先决条件检查时，会报PRVG-13632错误。
追加以下内容
#RAC-PUBLIC-IP 192.168.100.101 rac1 192.168.100.102 rac2 #RAC-PRIVATE-IP 10.10.10.101 rac1-priv 10.10.10.102 rac2-priv #RAC-VIP 192.168.100.201 rac1-vip 192.168.100.202 rac2-vip #RAC-SCAN-IP 192.168.100.200 rac-scan
1.3 关闭防火墙
- 关闭防火墙服务
systemctl disable firewalld.service
-
selinux配置
vi /etc/selinux/config把enforcing更改为disabled
# This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted -

注：
kernel.shmmax：
用于定义单个共享内存段的最大值。设置应该足够大，能在一个共享内存段下容纳下整个的 SGA。32 位 linux 系统：可取最大值为 4GB （ 4294967296bytes ） -1byte;64 位 linux 系统：可取的最大值为物理内存值 -1byte.
建议值为多于物理内存的一半，一般取值大于 SGA_MAX_SIZE 即可，可以取物理内存 -1byte
kernel.shmall ：
可以使用的共享内存的总页数, Linux 共享内存页大小为 4KB

2.2 Grid安装
-
上传Grid文件
把LINUX.X64_193000_grid_home.zip上传到/u01/app/19c/grid
cd /u01/app/19c/grid chown -R grid:oinstall LINUX.X64_193000_grid_home.zip -
切换grid用户解压
su - grid cd $ORACLE_HOME unzip LINUX.X64_193000_grid_home.zip等待解压完毕
-
配置DISPLAY变量
export DISPLAY=192.168.100.103:0.0 ./gridSetup.sh注：IP写自己宿主机的IP地址
-
安装过程
这里的SCAN NAME一定要和你/etc/hosts文件里的那个RAC-SCAN-IP的名称保持一致而不是和IP保持一致。

3.数据库安装（RAC1）
3.1上传安装包
-
以root用户上传LINUX.X64_193000_db_home.zip到/u01/app/oracle/product/19c/db_1下
-
更改所属用户，所属组
[root@rac1 ~]# cd /u01/app/oracle/product/19c/db_1 [root@rac1 db_1]# chown -R oracle:oinstall LINUX.X64_193000_db_home.zip
3.2 解压缩
-
切换用户
[root@rac1 db_1]# su - oracle Last login: Tue Apr 19 09:24:47 CST 2022 on pts/0 -
切换目录
[oracle@rac1:/home/oracle]$cd $ORACLE_HOME [oracle@rac1:/u01/app/oracle/product/19c/db_1]$cd /u01/app/oracle/product/19c/db_1 -
解压
unzip LINUX.X64_193000_db_home.zip
3.3 安装数据库
-
设置DISPLAY变量
[oracle@rac1:/u01/app/oracle/product/19c/db_1] export DISPLAY=192.168.100.66:0.0 -
运行安装程序
[oracle@rac1:/u01/app/oracle/product/19c/db_1] ./runInstaller注：
1.要投影安装界面的主机（192.168.100.66）的防火墙要关闭，否则会报类似以下错误，
2.如果使用Xshell连接的服务器或者虚拟机的话，投影的机器或者宿主机要安装xMananger。
[oracle@rac1:/u01/app/oracle/product/19c/db_1]$./runInstaller ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable. Can't connect to X11 window server using '192.168.100.66:0.0' as the value of the DISPLAY variable. -
安装过程
注：只安装数据库软件，安装数据库软件成功后，再创建实例。
主要是DNS的问题， 直接忽略即可。
点击“Yes”
分别以root用户在rac1和rac2上运行该脚本
点击“Close”，安装完成
4.建库(RAC1)
4.1 调取安装界面
切换到grid用户，调取安装界面创建数据库
[root@rac1 ~]# su - grid
Last login: Thu Apr 28 20:19:54 CST 2022
[grid@rac1:/home/grid]$export DISPLAY=192.168.100.66:0.0
[grid@rac1:/home/grid]$asmca
4.2 创建ASM的DG
关闭对话框
4.2 创建数据库
-
切换到oracle用户并调用安装界面
[grid@rac1:/home/grid]$su - oracle Password: Last login: Mon Apr 25 21:42:45 CST 2022 [oracle@rac1:/home/oracle]$export DISPLAY=192.168.100.66:0.0 [oracle@rac1:/home/oracle]$dbca -
创建过程
注：可以不创建容器数据库，直接创建数据库，也可以根据需求创建容器数据库后，创建可插拔数据库。
注：根据需求，决定是否开启归档，也可以在创建数据库后，开启归档，这里暂时不开启归档。
注：选择字符AL32UTF8字符集
注：根据需求选择是共享服务器模式还是独占服务器模式
直接忽略
到此结束
