1. 安装

sudo apt update
sudo apt -y install vim bash-completion wget
sudo apt -y upgrade

sudo reboot

curl -fsSL https://www.postgresql.org/media/keys/ACCC4CF8.asc|sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/postgresql.gpg

echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" |sudo tee  /etc/apt/sources.list.d/pgdg.list

sudo apt update
sudo apt -y install postgresql-12 postgresql-client-12

运行查看：systemctl status postgresql.service

 postgresql.service - PostgreSQL RDBMS
     Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)

2. 添加用户、创建数据库

切换超管postgres 用户 sudo su - postgres 给postgres密码：psql -c "alter user postgres with password 'StrongAdminPassw0rd'"

进入命令行：psql，创建数据库、创建用户、用户和库授权

postgres=# CREATE DATABASE mytestdb;
CREATE DATABASE
postgres=# CREATE USER mytestuser WITH ENCRYPTED PASSWORD 'MyStr0ngP@SS';
CREATE ROLE
postgres=# GRANT ALL PRIVILEGES ON DATABASE mytestdb to mytestuser;
GRANT

其他命令：列出所有库\l，退出\q

3. 开启远程连接

文件位置： /etc/postgresql/12/main/postgresql.conf

# Listen on all interfaces
listen_addresses = '*'

# Listen on specified private IP address
listen_addresses = '192.168.10.11'

修改g_hba.conf 文件在ipv4链接设置中添加一行.

#配置192.168.88.0网段的所有主机均可访问，24为子网掩码
host    all             all             192.168.88.0/24            md5
#测试环境不要求严格权限是可像如下配置
host    all             all             0.0.0.0/0            trust

重启数据库 sudo systemctl restart postgresql
