PostgreSQL随手笔记(2)

1. 服务器安装

1.1 源码安装

平台:Ubuntu 16.04 LTS

  • 1 下载源码,以9.6.2为例, https://github.com/postgres/postgres/archive/REL9_6_2.zip
  • 2 安装库依赖并安装
$ sudo apt install libreadline6-dev bison flex
$ ./configure
$ make && sudo make install

如果少了依赖包,重新安装后需要执行./configure && make clean && make && sudo make install

  • 3 默认安装位置/usr/local/pgsql/

1.2 软件仓库安装

$ deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main
$ wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | \  sudo apt-key add -$ sudo apt-get update

$ sudo apt-get install postgresql-9.4

1.3 安装后动作

不能用root权限运行PostgreSQL,添加添加postgres用户,并完成启动。

$ sudo adduser postgres
$ sudo mkdir /usr/local/pgsql/data
$ sudo chown postgres /usr/local/pgsql/data
$ su postgres

$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
$ touch /usr/local/pgsql/data/logfile
$ /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l /usr/local/pgsql/data/logfile start

启动完成, 测试连接

$ psql -h localhost -U postgres -w
