Centos 7.7下Oracle 11g RAC

Centos 7.7下Oracle 11g RAC部署

  1. 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

priv: 10.10.10.82

vip: 192.168.198.182

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

[[email protected] ~]# 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

[[email protected] ~]# 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

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 = 1048586

1.4关闭防火墙

[[email protected] ~]# systemctl stop firewalld

[[email protected] ~]# systemctl disable firewalld

[[email protected] ~]# systemctl status firewalld

 

1.5 关闭SELINUX

[[email protected] ~]# 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

[[email protected] ~]# 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

[[email protected] ~]# chmod 771 /oracle/app

2.3设置Oracle用户环境变量

 

[[email protected] ~]# su – oracle

[[email protected] ~]$ vi .bash_profile

# .bash_profile

 

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi

export PATH

export ORACLE_BASE=/oracle/app/oracle

3. UDEV绑盘

3.1创建4块新的虚拟磁盘

先关闭两边虚机

 

Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC

Centos 7.7下Oracle 11g RAC

以此分别创建3个1G,1个10G的磁盘

Centos 7.7下Oracle 11g RAC

以自己建的磁盘顺序依次绑定节点

 

 

Centos 7.7下Oracle 11g RAC  Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC Centos 7.7下Oracle 11g RAC

第二台虚机添加硬盘时选择使用现有磁盘

Centos 7.7下Oracle 11g RAC

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

Centos 7.7下Oracle 11g RAC

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

[[email protected] ~]# fdisk -l

 

Disk /dev/sda: 42.9 GB, 42949672960 bytes, 83886080 sectors

Units = sectors of 1 * 512 = 512 bytes

Disk /dev/mapper/centos-swap: 8485 MB, 8485076992 bytes, 16572416 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

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

[[email protected] ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sdb

36000c299fee8a318f3d12deab7b4991a

[[email protected] ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sdc

36000c2933c41c168f10bd3fee9abe77c

[[email protected] ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sdd

36000c29d9d88b533e4f69484ae8a58e9

[[email protected] ~]# /usr/lib/udev/scsi_id -g -u -d /dev/sde

36000c29e3a08e62f7c157aa0012e84d1

 

两边添加绑定文件

[[email protected] ~]# 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

[[email protected] ~]# systemctl status systemd-udevd.service

[[email protected] ~]# systemctl enable systemd-udevd.service

[[email protected] ~]# /usr/sbin/udevadm control --reload-rules

4安装集群软件

4.1先上传grid安装包到grid家目录下

[[email protected] ~]$ 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

[[email protected] ~]$ unzip p13390677_112040_Linux-x86-64_3of7.zip

[[email protected] ~]$ 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

[[email protected] ~]$ cd grid/

[[email protected] grid]$ ./runInstaller

 

Centos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RAC

两边执行自动修复脚本

 

Centos 7.7下Oracle 11g RACCentos 7.7下Oracle 11g RAC

 

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

Centos 7.7下Oracle 11g RAC

在执行第二个脚本时会出现版本bug

Centos 7.7下Oracle 11g RAC

要在新开窗口执行

Centos 7.7下Oracle 11g RAC

Centos 7.7下Oracle 11g RAC

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

[[email protected] ~]$ crsctl check crs
