最全的Centos6.10详细安装Oracle 11G R2图文教程

Posted 2021-01-01

平台：Centos 6.10 x64 带图形
配置4G 4核心cpu 200G硬盘

第一步、安装依赖

yum install -y binutils compat-libcap1 compat-libstdc++-33  gcc gcc-c++ glibc glibc-devel ksh libgcc libstdc++ libstdc++-devel libaio libaio-devel  make sysstat unixODBC-devel pdksh

下载javarpm包，安装oracle java

[[email protected] ~]# rpm -ivh jdk-8u121-linux-x64.rpm 
    Preparing...                ########################################### [100%]
   1:jdk1.8.0_121           ########################################### [100%]

第二步、创建所需用户和组

创建oracle用户并设置密码

[[email protected] ~]# useradd oracle
[[email protected] ~]# passwd oracle

然后登陆图形界面测试一下oracle用户
测试正常

创建用户组

[[email protected] ~]# groupadd oinstall
[[email protected] ~]# groupadd dba

修改oracle用户组

usermod -g oinstall -G dba oracle

第三步、修改内核参数

追加一段内核参数

[[email protected] ~]# vim /etc/sysctl.conf
........
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
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 = 1048576

执行生效
[[email protected] ~]# sysctl -p

修改文件打开限制，追加一段

[[email protected] ~]# vim /etc/security/limits.conf
.......
oracle             soft    nproc           4096
oracle             hard    nproc           65536
oracle             soft    nofile          4096
oracle             hard    nofile          65536

创建oracle安装目录

[[email protected] ~]# mkdir -p /u01/app/
[[email protected] ~]# chown -R oracle:oinstall /u01/app/
[[email protected] ~]# chmod -R 775 /u01/app/

重启服务器，使limit生效

第四步、添加环境变量，准备安装

使用oracle用户登陆

[[email protected] ~]# su - oracle
[[email protected] ~]$ vim .bash_profile
#追加下面这段
ORACLE_BASE=/u01/app/oracle
ORACLE_SID=sales
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_BASE ORACLE_SID ORACLE_HOME
PATH=$ORACLE_HOME/bin:$PATH

检查主机名能访问不

[[email protected] ~]$ ping o1
PING o1 (192.168.1.18) 56(84) bytes of data.
64 bytes from o1 (192.168.1.18): icmp_seq=1 ttl=64 time=0.061 ms

检查正常

解压oracle安装包

[[email protected] ~]$ unzip linux.x64_11gR2_database_1of2.zip
[[email protected] ~]$ unzip linux.x64_11gR2_database_2of2.zip

第五步、开始安装

进入安装目录，开始安装

[[email protected] ~]$ cd database/
[[email protected] database]$ ./runInstaller

然后弹出安装程序，去掉下面那个勾，点next

再点next

选择server，再点next

再点next

选择高级安装，再点next

再点next

点击字符集，然后勾选UTF8，然后next

开始检查依赖包，其实这些包都装了的，只是版本高了，勾选ignore all，然后next

点击save response file可以保存选择配置，点finish开始安装

安装中

安装完成后有提示，蓝色的是em控制台访问地址，点ok

然后提示要执行两个脚本，使用root执行

[[email protected] ~]# sh /u01/app/oraInventory/orainstRoot.sh 
Changing permissions of /u01/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.

Changing groupname of /u01/app/oraInventory to oracle.
The execution of the script is complete.
[[email protected] ~]#
