linux下安装PostgreSQL

OS：suselinux11（64bit）
PostgreSQL：PostgreSQL9.1（64bit）
1、建用户及目录
linux:/home # groupadd postgres
linux:/home # useradd postgres -g postgres
linux:/home # mkdir /home/postgres
linux:/home # chown postgres:postgres /home/postgres
linux:/home # passwd postgres
2、用root运行安装（不能以postgres运行安装）
linux:/opt # mkdir /opt/PostgreSQL
linux:/opt # chown postgres:postgres /opt/PostgreSQL
linux:/opt/PostgreSQL # chmod +x postgresql-9.1.1-1-linux-x64.bin
linux:/opt/PostgreSQL # ./postgresql-9.1.1-1-linux-x64.bin

3、相关配置
（1）环境变量
:~> vi .profile(new file)
export PGSQL_HOME=/opt/PostgreSQL/9.1
export PATH=$PGSQL_HOME/bin:$PATH
#export PGDATAS=$PGSQL_HOME/datas
export PGDATA=$PGSQL_HOME/data
export PGDATABASE=postgres
export PGUSER=postgres
#export PGPORT=1234
export PGLOCALEDIR=$PGSQL_HOME/share/locale
export MANPATH=$MANPATH:$PGSQL_HOME/share/man
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PGSQL_HOME/lib
:~> . .profile
配置如上环境表里之后，可以使用psql连接数据库：
> psql
Password:
psql.bin (9.1.1)
Type "help" for help.
postgres=# help
You are using psql, the command-line interface to PostgreSQL.
Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit
postgres=#
（2）网络配置
加网络信任关系：
----详细信息请参考PostgreSQL document，20.1. pg_hba.conf 文件
vi /opt/PostgreSQL/9.1/data/pg_hba.conf
添加一行：host    all         all                           trust
重启数据库：
:~> pg_ctl restart
waiting for server to shut down.... done
server stopped
server starting
此时可以用PgAdmin远程登录postgres用户了，此时只有一个库postgres。
