Posted 2020-10-27

1.修改主机名：
[[email protected] ~]# sed -i "s/HOSTNAME=localhost.localdomain/HOSTNAME=oracledb/" /etc/sysconfig/network
2.设置ip地址：

虚机安装的话，建议使用仅主机模式。固定ip地址。
3.修改hosts文件
vi /etc/hosts 192.168.138.120 oracledb
3.安装依赖包，需安装如下包：

4.创建用户和组
[[email protected] ~]# sysctl -p
[[email protected] ~]# groupadd -g 200 oinstall
[[email protected] ~]# groupadd -g 201 dba
[[email protected] ~]# useradd -u 440 -g oinstall -G dba oracle
[[email protected] ~]# passwd oracle
5.修改内核参数
[[email protected] ~]# vi/etc/sysctl.conf #末尾添加如下
net.ipv4.ip_local_port_range= 9000 65500
fs.file-max = 6815744
kernel.shmall = 10523004
kernel.shmmax = 6465333657
kernel.shmmni = 4096
kernel.sem = 250 32000 100128
net.core.rmem_default=262144
net.core.wmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_max=1048576
fs.aio-max-nr = 1048576
6.修改系统资源限制
[[email protected] ~]# vi/etc/security/limits.conf #末尾添加如下
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

[[email protected] ~]# vi/etc/pam.d/login
session required pam_namespace.so #下面添加一条pam_limits.so
session required pam_limits.so

[[email protected] ~]# vi/etc/profile #
if [ $USER ="oracle" ]; then
if [ $SHELL = "/bin/ksh" ];then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
7.创建安装目录及设置权限，命令行输入：
[[email protected] ~]# mkdir /opt/oracle/app/
[[email protected] ~]# mkdir /opt/oracle/oradata/
[[email protected] ~]# chmod 755 /opt/oracle/
[[email protected] ~]# chmod 775 /opt/oracle/app/
[[email protected] ~]# chown oracle.oinstall -R /opt/oracle/

8.设置环境变量(su - oracle )
[[email protected] ~]$ vi ~/.bash_profile
export ORACLE_BASE=/opt/oracle/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1
export PATH=$PATH:$ORACLE_HOME/bin
export ORACLE_SID=orcl
export ORACLE_PID=orcl
[[email protected] ~]$ source .bash_profile
9.以Oracle用户登陆系统，进行解压并安装Oracle。
