Centos 7.7下Oracle 11g RAC部署
- 操作系统环境
1.1linux操作系统配置
两台主机IP规划信息如下：
|
rac1 |
rac2 |
|
Ip：192.168.198.180 |
Ip：192.168.198.181 |
|
priv:10.10.10.81 |

vip: 192.168.198.183 |
|
scan-ip:192.168.198.184 |
|
|
Linux系统版本均为7.7 |
|
|
Oracle版本为11.2.0.4.0 |
|
1.2hosts文件配置
[root@rac1 ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
#public
192.168.198.180 rac1
192.168.198.181 rac2
#vip
192.168.198.182 rac1-vip
192.168.198.183 rac2-vip
#priv
10.10.10.81 rac1-priv
10.10.10.82 rac2-priv
#scan
192.168.198.184 rac-cluster-scan
两个节点的hosts文件内容要相同
1.3配置内核参数
[root@rac1 ~]# vi /etc/sysctl.conf
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 8389934592 # kernel.shmmax要以自己实际内存大小而定
kernel.shmall = 268435456
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

1.4关闭防火墙
[root@rac1 ~]# systemctl stop firewalld
[root@rac1 ~]# systemctl disable firewalld
[root@rac1 ~]# systemctl status firewalld
1.5 关闭SELINUX
[root@rac1 ~]# vi /etc/selinux/config
# 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
1.6安全限制调整
[root@rac1 ~]# vi /etc/security/limits.conf
# /etc/security/limits.conf
#
#This file sets the resource limits for the users logged in via PAM.
#It does not affect resource limits of the system services.
#
#Also note that configuration files in /etc/security/limits.d directory,
#which are read in alphabetical order, override the settings in this
#file in case the domain is the same or more specific.
#That means for example that setting a limit for wildcard domain here
#can be overriden with a wildcard setting in a config file in the
#subdirectory, but a user specific setting here can be overriden only
#with a user specific setting in the subdirectory.
#
#Each line describes a limit for a user in the form:
#
#<domain> <type> <item> <value>
#
#Where:
#<domain> can be:
# - a user name
# - a group name, with @group syntax
# - the wildcard *, for default entry
# - the wildcard %, can be also used with %group syntax,
# for maxlogin limit
#
#<type> can have the two values:
# - "soft" for enforcing the soft limits
# - "hard" for enforcing hard limits
#
#<item> can be one of the following:
# - core - limits the core file size (KB)
# - data - max data size (KB)
# - fsize - maximum filesize (KB)
# - memlock - max locked-in-memory address space (KB)
# - nofile - max number of open file descriptors
# - rss - max resident set size (KB)
# - stack - max stack size (KB)
# - cpu - max CPU time (MIN)
# - nproc - max number of processes
# - as - address space limit (KB)
# - maxlogins - max number of logins for this user
# - maxsyslogins - max number of logins on the system
# - priority - the priority to run user process with
# - locks - max number of file locks the user can hold
# - sigpending - max number of pending signals
# - msgqueue - max memory used by POSIX message queues (bytes)
# - nice - max nice priority allowed to raise to values: [-20, 19]
# - rtprio - max realtime priority
#
#<domain> <type> <item> <value>
#
#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student - maxlogins 4
# End of file

3. UDEV绑盘
3.1创建4块新的虚拟磁盘
先关闭两边虚机
以此分别创建3个1G，1个10G的磁盘
以自己建的磁盘顺序依次绑定节点
第二台虚机添加硬盘时选择使用现有磁盘
找到刚刚创建的4块磁盘并绑定相同节点
3.2修改虚机参数
找到虚机.vmx参数文件
编辑该文件在文件末尾加上
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.locking = "FALSE"
disk.enableUUID = "TRUE"
两边都要添加之后保存文件再开机
3.3绑定磁盘组
[root@rac1 ~]# fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes, 83886080 sectors

I/O size (minimum/optimal): 512 bytes / 512 bytes
先查看两边磁盘是否挂接成功
查看自己两边磁盘UUID是否相同
[root@rac1 ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sdb
36000c299fee8a318f3d12deab7b4991a

[root@rac1 ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sde
36000c29e3a08e62f7c157aa0012e84d1
两边添加绑定文件
[root@rac1 ~]# vi /etc/udev/rules.d/99-oracle-asmdevices.rules
KERNEL=="sdb", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/sdb", RESULT=="36000c299fee8a318f3d12deab7b4991a", SYMLINK+="asm-crs1", OWNER="grid", GROUP="asmadmin", MODE="0660"

两边编辑绑定文件后，依次执行以下命令
[root@rac1 ~]# systemctl status systemd-udevd.service
[root@rac1 ~]# systemctl enable systemd-udevd.service
[root@rac1 ~]# /usr/sbin/udevadm control --reload-rules
[root@rac1 ~]# /usr/sbin/udevadm trigger --type=devices

4安装集群软件
4.1先上传grid安装包到grid家目录下
[grid@rac1 ~]$ ll
-rwxrwxr-x 1 grid oinstall 1205251894 2月 27 2015 p13390677_112040_Linux-x86-64_3of7.zip
上传过来后要修改grid安装包权限
4.2解压安装包
[grid@rac1 ~]$ unzip p13390677_112040_Linux-x86-64_3of7.zip
[grid@rac1 ~]$ ll
drwxr-xr-x 7 grid oinstall 156 8月 27 2013 grid
drwxr-xr-x 3 grid oinstall 18 7月 5 21:43 oradiag_grid
-rwxrwxr-x 1 grid oinstall 1205251894 2月 27 2015 p13390677_112040_Linux-x86-64_3of7.zip
[grid@rac1 ~]$ cd grid/
[grid@rac1 grid]$ ./runInstaller
两边执行自动修复脚本
依次再在两个节点用root用户执行两个脚本，先执行脚本1按节点一二顺序，再执行脚本2按节点一二顺序
在执行第二个脚本时会出现版本bug
要在新开窗口执行
安装完成后显示的报错可以忽略
4.3检查grid集群是否安装成功
[grid@rac1 ~]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

5.安装数据库软件
上传数据库压缩包到oracle家目录下并赋权
[oracle@rac1 ~]$ ll
-rwxrwxr-x 1 oracle oinstall 1212620273 Nov 7 2019 p13390677_112040_Linux-x86-64_1of7.zip
-rwxrwxr-x 1 oracle oinstall 113112960 Nov 7 2019 p13390677_112040_Linux-x86-64_2of7.zip
开始安装
[oracle@rac1 ~]$ cd database/
[oracle@rac1 database]$ ./runInstaller
执行以上脚本
6 安装asmca
使用grid用户执行asmca命令
[grid@rac1 ~]$ asmca
7 安装dbca
[oracle@rac1 ~]$ dbca
