|
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

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
