具体安装

1. Install the repository RPM:

   yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7-x86_64/pgdg-redhat10-10-2.noarch.rpm

2. Install the client packages:

   yum install postgresql10

3. Optionally install the server packages:

   yum install postgresql10-server

4. Optionally initialize the database and enable automatic start:

   /usr/pgsql-10/bin/postgresql-10-setup initdb
   systemctl enable postgresql-10
   systemctl start postgresql-10

远程连接

1. Modify user password

   su - postgres

   切换用户，执行后提示符会变为 '-bash-4.2$'

   psql -U postgres

   登录数据库，执行后提示符变为 'postgres=#'

   ALTER USER postgres WITH PASSWORD 'postgres';

   设置postgres用户密码为postgres

   \q

   退出数据库

2. Open remote access

   vim /var/lib/pgsql/10/data/postgresql.conf

   修改#listen_addresses = 'localhost'

   为 listen_addresses='*'

   当然，此处'*'也可以改为任何你想开放的服务器IP

3. Trusted remote connection

   vim /var/lib/pgsql/10/data/pg_hba.conf

   修改如下内容，信任指定服务器连接

   # IPv4 local connections:

   host    all            all      127.0.0.1/32      ident

   host all all 0.0.0.0/0 （需要连接的服务器IP） md5

4. Reboot service

   systemctl restart postgresql-10

5. Test connection
