一键安装oracle数据库

Posted 2020-09-08 ChavinKing

准备工作：通过ftp工具上传oracle安装软件到linux系统/mnt目录下，并通过unzip命令解压软件。

1、创建oracle图形界面安装前脚本（root用户操作），按如下方法操作即可：
[[email protected] ~]# cd /mnt
[[email protected] mnt]# vim oracleinstall
--输入上面命令后出现的界面下按“i”，并输入如下内容后，点击“esc”键，输入“：wq”并回车保存。其中#1.create groups and users部分根据实际情况修改具体环境变量值即可。
#!/bin/bash
#Purpose:Create and config oracle install.
#Usage:Log on as the superuser(‘root‘)
groupadd dba -g 111
groupadd oinstall -g 110
useradd oracle -u 110 -g 110 -G 111
echo "oracle" | passwd --stdin oracle
echo "export TMP=/tmp">> /home/oracle/.bash_profile
echo ‘export TMPDIR=$TMP‘>>/home/oracle/.bash_profile
echo "export ORACLE_HOSTNAME=localhost.localdomain">> /home/oracle/.bash_profile
echo "export ORACLE_SID=orcl">> /home/oracle/.bash_profile
echo "export ORACLE_BASE=/u01/app/oracle">> /home/oracle/.bash_profile

echo "export LANG=en_US" >> /home/oracle/.bash_profile
echo "export NLS_LANG=american_america.AL32UTF8" >> /home/oracle/.bash_profile
echo "export NLS_DATE_FORMAT=‘yyyy-mm-dd hh24:mi:ss‘" >> /home/oracle/.bash_profile
mkdir -p /u01

chown -R oracle:oinstall /u01

echo ‘else‘ >> /etc/profile
echo ‘ulimit -u 16384 -n 65536‘ >> /etc/profile
echo ‘fi‘ >> /etc/profile
echo ‘fi‘ >> /etc/profile
cp /etc/sysctl.conf /etc/sysctl.conf.bak
echo "fs.aio-max-nr = 1048576" >> /etc/sysctl.conf

sysctl -p

2、root用户下数据xhost +并回车，如下：
[[email protected] mnt]# xhost +
------------------------------------------------------------------------------------------------------------------------------------------------------------
3、切换到oracle用户下，并进入数据库安装软件目录，执行./runInstall命令，在出现图形界面后根据windows平台安装步骤执行即可（与windows平台安装oracle数据库唯一不同的地方是：最后要以root权限执行2个脚本），此处图形安装界面略。

注意：先决条件检查步骤需要根据未通过条件进行先决条件处理。
