postgreSQL在linux中安装详解

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

2.       [root@william ~]# /postgresql-8.4.1-1-linux-x64.bin – –mode text (我这里是放在了root路径下)

5.       Password :[ 输入密码]

6.       Retype password :[ 重复输入]

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.   [root@william ~]# 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)

[root@william ~]# chown -R postgres.postgres /home/PostgreSQL/* (将改文件的ownergroup都配置为postgres

12.   [root@william ~]# 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.   [root@william ~]#su – postgres(转到postgres用户下)

14.   [postgres@william ~]$/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。
