centos7安装postgresql

1.安装

yum install postgresql-server
yum install postgresql-contrib

2.启动

systemctl status postgresql


如果报错：
[root@VM_176_134_centos ~]# systemctl start postgresql
Job for postgresql.service failed because the control process exited with error code. See "systemctl status postgresql.service" and "journalctl -xe" for details.

则执行数据库初始化命令
postgresql-setup initdb

3.设置密码

[root@VM_176_134_centos data]# su postgres
bash-4.2$ psql
psql (9.2.23)
Type "help" for help.

postgres=# ALTER USER postgres WITH PASSWORD '密码';
ALTER ROLE

4.开放远程连接

cd /var/lib/pgsql/data


vi pg_hba.conf
将文件结尾处的
# host    all             all             127.0.0.1/32            ident
改为
# host    all             all             127.0.0.1/32            ident
host    all             all             0.0.0.0/0                password


vi postgresql.conf
将
#listen_addresses = 'localhost'         # what IP address(es) to listen on;
改为
listen_addresses = '*'         # what IP address(es) to listen on;

systemctl restart postgresql
