一. 环境配置
虚拟机安装建议分2G内存,30G硬盘。
关闭防火墙(或放行相关端口)
systemctl stop firewalld systemctl disable firewalld
关闭selinux
修改SELINUX=disabled
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
重启
reboot
将oracle-database-ee-19c-1.0-1.x86_64.rpm
和oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
上传到/opt
下
二. 依赖安装
安装oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
yum -y localinstall /opt/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
三. 安装配置Oracle 19c
安装Oracle 19c
yum -y localinstall /opt/oracle-database-ee-19c-1.0-1.x86_64.rpm
初始化Oracle数据库(时间较长)
/etc/init.d/oracledb_ORCLCDB-19c configure
配置环境变量
却换到oracle
用户
su - oracle
添加环境变量
vi /home/oracle/.bash_profile
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/.local/bin:$HOME/bin export PATH export ORACLE_HOME=/opt/oracle/product/19c/dbhome_1 export PATH=$PATH:/opt/oracle/product/19c/dbhome_1/bin export ORACLE_SID=ORCLCDB
使环境变量生效
source /home/oracle/.bash_profile
登陆数据库
sqlplus / as sysdba
修改system
密码为123456
alter user system identified by 123456;
退出数据库
exit;
四. 设置数据库监听自启动
修改/etc/oratab
文件N
为Y
vi /etc/oratab
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by either Database Configuration Assistant while creating
# a database or ASM Configuration Assistant while creating ASM instance.# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third field indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
ORCLCDB:/opt/oracle/product/19c/dbhome_1:Y
在/etc/rc.local
中添加需执行的命令
su root # 却换为root用户
vi /etc/rc.local
#!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. touch /var/lock/subsys/local su - oracle -c 'lsnrctl start' su - oracle -c 'dbstart'
修改$ORACLE_HOME/bin/dbstart
文件,修改ORACLE_HOME_LISTNER=$ORACLE_HOME
vi $ORACLE_HOME/bin/dbstart
$ORACLE_HOME/bin/dbstart 文件局部
... ##################################### LOGMSG="logger -puser.alert -s " trap 'exit' 1 2 3 # for script tracing case $ORACLE_TRACE in T) set -x ;; esac # Set path if path not set (if called from /etc/rc) SAVE_PATH=/bin:/usr/bin:/etc:${PATH} ; export PATH SAVE_LLP=$LD_LIBRARY_PATH # First argument is used to bring up Oracle Net Listener ORACLE_HOME_LISTNER=$ORACLE_HOME if [ ! $ORACLE_HOME_LISTNER ]; then echo "Since ORACLE_HOME is not set, cannot auto-start Oracle Net Listener." echo "Usage: $0 ORACLE_HOME" else ...
设置CentOS7,8开机执行/etc/rc.local
文件(CentOS7,8开机不执行/etc/rc.local
文件)
给 /etc/rc.d/rc.local
添加 可执行权限
chmod a+x /etc/rc.d/rc.local
将 rc-local 服务设置成开机启动(默认状态是 static,会被其他service服务调用执行。不过还是修改一下,以防那个服务被停用就牵连了)
systemctl enable rc-local
重启,用sqldeveloper
链接,验证是否成功
reboot
删除/opt
下oracle-database-ee-19c-1.0-1.x86_64.rpm
和oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
rm /opt/oracle-database-ee-19c-1.0-1.x86_64.rpm /opt/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
