在此博客中,我将演示如何在Ubuntu上安装PostgreSQL数据库。
Step #1:
列出了已经安装的Postgres相关软件包
dpkg -l | grep postgres
例如:
dpkg -l | grep postgres
ii postgresql-12 12.12-0ubuntu0.20.04.1 amd64 object-relational SQL database, version 12 server
ii postgresql-client-12 12.12-0ubuntu0.20.04.1 amd64 front-end programs for PostgreSQL 12
ii postgresql-client-common 214ubuntu0.1 all manager for multiple PostgreSQL client versions
ii postgresql-common 214ubuntu0.1 all PostgreSQL database-cluster manager
Step #2:
如果不需要某些软件包,则运行“ sudo apt-get - purge remove ...”命令清除它们:
例如:
sudo apt-get --purge remove postgresql-12 postgresql-client-12
Step #3:
创建文件存储库配置:
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
Step #4:
导入存储库签名密钥:
wget -qO- https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo tee /etc/apt/trusted.gpg.d/pgdg.asc &>/dev/null
Step #5:
更新包列表:
sudo apt update
Step #6:
安装最新版本的postgresql:
sudo apt install postgresql postgresql-client -y
Step #7:
如果您想要特定版本,请使用“ Postgresql-13”或类似版本,而不是“ PostgreSql”:
sudo apt install postgresql-13 postgresql-client-13 -y
Step #8:
检查状态
sudo systemctl status postgresql
Step #9:
检查PostgreSQL客户端版本
psql --version
例如:
dmi@dmi-VirtualBox:~$ psql --version
psql (PostgreSQL) 13.9 (Ubuntu 13.9-1.pgdg20.04+1)
dmi@dmi-VirtualBox:~$
Step #10:
检查PostgreSQL Server版本
sudo -u postgres psql
postgres=# select version();
例如:
postgres=# select version();
version
-----------------------------------------------------------------------------------------------------------------------------------
PostgreSQL 13.9 (Ubuntu 13.9-1.pgdg20.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0, 64-bit
