切換到root賬戶，

#安裝yum 源

yum install https://download.postgresql.org/pub/repos/yum/11/redhat/rhel-7-x86_64/pgdg-centos11-11-2.noarch.rpm

#安裝postgresql11

yum install postgresql11

yum install postgresql11-server

#初始化

/usr/pgsql-11/bin/postgresql-11-setup initdb

#開機開啟

systemctl enable postgresql-11

#啟動db

systemctl start postgresql-11

 

#登錄postgresql並設置密碼

su - postgres

psql

#修改密碼為dbpasswd

ALTER USER postgres WITH PASSWORD 'dbpasswd';

#退出psql

\q 

#退出bash

exit

 

#修改支持遠程登錄

vi /var/lib/pgsql/11/data/postgresql.conf

#其中設置 listen_addresses = '*' 

vi /var/lib/pgsql/11/data/pg_hba.conf

#最后一行增加

host all all 0.0.0.0/0 md5

 

#修改后保存，重啟postgresql

 systemctl restart postgresql-11

 

#創建db、創建用戶、分配權限

CREATE DATABASE testdb;

CREATE USER testuser CREATEDB LOGIN PASSWORD 'dbpasswd';

GRANT ALL ON DATABASE testdb TO testuser;

#刪除db、刪除用戶

drop database testdb;

drop role testuser;
