3、安装

[root@centos7-6 pg-rpm]# rpm -ivh postgresql12-libs-12.2-1PGDG.rhel7.x86_64.rpm
[root@centos7-6 pg-rpm]# rpm -ivh postgresql12-12.2-1PGDG.rhel7.x86_64.rpm 
[root@centos7-6 pg-rpm]# rpm -ivh postgresql12-server-12.2-1PGDG.rhel7.x86_64.rpm

4、初始化数据库并设置自启动

4.1、通过systemctl管理数据库

/usr/pgsql-12/bin/postgresql-12-setup initdb 
systemctl enable postgresql-12
systemctl start postgresql-12
systemctl status postgresql-12

4.2、通过PG自带的工具pg_ctl管理

4.2.1、配置环境变量

-bash-4.2$ pwd
/var/lib/pgsql
-bash-4.2$ 
-bash-4.2$ vi .bash_profile
#追加内容
export PATH=$PATH:/usr/pgsql-12/bin

-bash-4.2$ source .bash_profile

 4.2.2、pg_ctl管理数据库

[root@centos7-6 ~]# su - postgres
-bash-4.2$ pg_ctl stop
-bash-4.2$ pg_ctl start
-bash-4.2$ pg_ctl status

5、日志路径

 $PGDATA/log
