postgreSQL在linux中安装详解 收藏
这里安装8.4.4版本,首先下载postgresql-8.4.4-1-linux.bin。
(http://www.postgresql.org/download/)下载linux32版本的
1. 如果该文件不在linux系统中,将其从Windows拖到linux系统中,放到任意一个目录下,最好放在/opt或者/home。推荐一个Windows文件转到linux的工具:WinSCP3
(
1、打开一个终端,su -成root用户;
2、chmod +xpostgresql-8.4.4-1-linux.bin
3、./postgresql-8.4.4-1-linux.bin //运行这个命令就可以安装软件了)
2. [[email protected] ~]# /postgresql-8.4.1-1-linux-x64.bin – –mode text (我这里是放在了root路径下)

Setup has finished installing PostgreSQL on your computer.
Launch Stack Builder at exit?
10. Stack Builder may be used to download and install additional tools, drivers and applications to complement your PostgreSQL installation. [Y/n]: y(这里是继续安装额外的工具,驱动和先关应用程序)
到这里数据库就安装成功了,然后就需要配置用户,环境变量,以及初始化数据库
11. [[email protected] ~]# cp .bash_profile .bashrc /home/PostgreSQL/8.4/ (将文件拷到相应目录,这个是配置环境变量的)
[[email protected] ~]# chown -R postgres.postgres /home/PostgreSQL/* (将改文件的owner和group都配置为postgres)
12. [[email protected] ~]# ls -ltr /home/PostgreSQL/8.4/.bash* (查看下是否已更改)
-rw-r–r– 1 postgres postgres 174 Nov 10 19:18 /home/PostgreSQL/8.4/.bash_profile
-rw-r–r– 1 postgres postgres 176 Nov 10 19:18 /home/PostgreSQL/8.4/.bashrc
初始化该数据库集群的缺省区域和字符集编码
13. [[email protected] ~]#su – postgres(转到postgres用户下)
14. [[email protected] ~]$/opt/PostgreSQL/8.4/bin/initdb –D /opt/PostgreSQL/8.4/data/(初始化数据库集群的缺省区域和字符集编码)
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale en_US.
The default database encoding has accordingly been set to LATIN1.
The default text search configuration will be set to "english".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the
next time you run initdb.
Success. You can now start the database server using:
postgres -D /home/PostgreSQL/8.4/data
or
pg_ctl -D /home/PostgreSQL/8.4/data -l logfile start
恭喜你,现在就把所有的都装完了!
常用命令:
Createdb
创建数据库
Createuser
创建数据库用户
Dropdb
删除数据库
Dropuser
删除数据库用户
Psql
交互式PostgreSQL前端工具,可以用它来操作数据库
Initdb
初始化postgreSQL数据库
例如:
psql \q à 退出psql命令符界面
psql \c dbname à 连接数据库
pg_ctl -D /opt/PostgreSQL/8.4/data/ status à 查看当前服务状态
pg_ctl -D /opt/PostgreSQL/8.4/data/ start à 启动服务
pg_ctl -D /opt/PostgreSQL/8.4/data/ stop à 停止服务
远程登录设置:
●打开opt/PostgreSQL/8.4/data/pg_hba.conf,像下面一样添加一行代码:(红色为添加的)
# IPv4 local connections:
host all all 0.0.0.0/0 md5
host all all 127.0.0.1/32 md5
这行代码表示所有IP地址的所有用户可以通过md5加密的方式远程登录。
●打开opt/PostgreSQL/8.4/data/postgresql.conf
按照下面的写:
listen_addresses = ‘*‘
port = 5432
max_connections = 100
这里表示监听来自所有IP的响应。
