sudo apt update
sudo apt install -y wget gnupg2
sudo sh -c 'echo "deb https://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
curl -fsSL https://www.postgresql.org/media/keys/ACCC4CF8.asc|sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/postgresql.gpg
sudo apt update

2 安装配置 PostgreSQL​

2.1 Apt 方式安装 PostgreSQL​

sudo apt install -y postgresql-16

2.2 启动 PostgreSQL​

sudo systemctl enable postgresql
sudo systemctl start postgresql
sudo systemctl status postgresql

2.3 配置数据库授权​

sudo -u postgres psql
CREATE DATABASE jumpserver;
CREATE USER jumpserver WITH PASSWORD 'KXOeyNgDeTdpeu9q';
GRANT ALL PRIVILEGES ON DATABASE jumpserver TO jumpserver;
\q

2.4 配置远程访问​

sudo vim /etc/postgresql/16/main/postgresql.conf
