Linux平台 Oracle 19c RAC安装指导: Part1:Linux平台 Oracle 19c RAC安装Part1:准备工作 Part2:Linux平台 Oracle 19c RAC安装Part2:GI配置 Part3:Linux平台 Oracle 19c RAC安装Part3:DB配置

本文安装环境:OEL 7.6 + Oracle 19.3 GI & RAC

三、GI(Grid Infrastructure)安装

3.1 解压GI的安装包

su - grid 解压 GRID 到 GRID用户的$ORACLE_HOME下

[grid@db193 grid]$ pwd
/u01/app/19.3.0/grid
[grid@db193 grid]$ unzip /u01/media/LINUX.X64_193000_grid_home.zip 

3.2 安装配置Xmanager软件

在自己的Windows系统上成功安装Xmanager Enterprise之后,运行Xstart.exe可执行程序, 配置如下

Session:db193 Host:192.168.1.193 Protocol:SSH User Name:grid Execution Command:/usr/bin/xterm -ls -display $DISPLAY 点击RUN,输入grid用户的密码可以正常弹出命令窗口界面,即配置成功。 当然也可以通过开启Xmanager - Passive,直接在SecureCRT连接的会话窗口中临时配置DISPLAY变量直接调用图形: export DISPLAY=192.168.1.31:0.0

3.3 共享存储LUN的赋权

在《Linux平台 Oracle 19c RAC安装Part1:准备工作 -> 1.3 共享存储规划》中已完成绑定和权限,这里不需要再次操作。

--只需确认两个节点链接文件(/dev/asm*)对应的sd[b-g]2的权限正确即可:
# ls -l /dev/sd?2
brw-rw---- 1 root disk     8,  2 Jul 31 09:13 /dev/sda2
brw-rw---- 1 grid asmadmin 8, 18 Jul 31 18:06 /dev/sdb2
brw-rw---- 1 grid asmadmin 8, 34 Jul 31 18:06 /dev/sdc2
brw-rw---- 1 grid asmadmin 8, 50 Jul 31 18:06 /dev/sdd2
brw-rw---- 1 grid asmadmin 8, 66 Jul 31 17:10 /dev/sde2
brw-rw---- 1 grid asmadmin 8, 82 Jul 31 17:10 /dev/sdf2
brw-rw---- 1 grid asmadmin 8, 98 Jul 31 17:10 /dev/sdg2

3.4 使用Xmanager图形化界面配置GI

Xmanager通过grid用户登录,进入$ORACLE_HOME目录,运行gridSetup配置GI

$ cd $ORACLE_HOME
$ ./gridSetup.sh

其实从12cR2开始,GI的配置就跟之前有一些变化,19c也一样,下面来看下GI配置的整个图形化安装的过程截图:

注:这里Public网卡这里用的enp0s3,ASM&Private这里用的enp0s8。

注:这里有一个新的存储GIMR的,之前12c、18c版本都是选择是外部冗余的一个40G大小的盘(当初给很多刚接触安装12cRAC的DBA造成了不适),而在19c安装中可以看到默认就是不选择的,恢复了11g时代的清爽感,这点我个人觉得很赞。

注:这里跟之前区别不大,我依然是选择3块1G的盘,Normal冗余作为OCR和voting disk。

注:这里检查出来的问题都需要认真核对,确认确实可以忽略才可以点击“Ignore All”,如果这里检测出缺少某些RPM包,需要使用yum安装好。我这里是自己的测试环境,分的配置较低,所以有内存和swap检测不通过,实际生产环境不应出现。

注:执行root脚本,确保先在一节点执行完毕后,再在其他节点执行。

第一个节点root执行脚本:

[root@db193 ~]# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory.

[root@db195 ~]# 

这段时间从打印的日志来看,虽然耗时也比以前11g时代长,但实际相比12c的上一个版本18c来说却缩短了不少。 root脚本成功执行完后继续安装:

注:最后这个报错提示,查看日志发现是因为使用了一个scan ip的提示,可以忽略。

至此GI配置完成。

3.5 验证crsctl的状态

crsctl stat res -t查看集群资源状态信息,看到19c实际相对18c来说,有做很多的精简,更趋于稳定性因素考虑~
