PostgreSQL安装体验

今天开始利用闲暇时间来学点PGsql。下面我贴出我的初次安装体验。
1、遇到两个错误：
1）、configure: error: readline library not found
解决方法：
安装libtermcap-devel-2.0.8-46.1.i386.rpm
和readline-devel-5.1-1.1.i386.rpm
安装过程就不多说了。
checking for inflate in -lz... no
2）、configure: error: zlib library not found
解决方法：
安装zlib-devel-1.2.3-3.i386.rpm
然后./configurate;make;make install
如果到了这一步就表示安装成功了。
Postgresql installation complete.
PGsql 安装成功
2、后续设置
[root @localhost pgsql]# make dir /usr/local/pgsql/data
POSTGRE好像不能用ROOT来操作。只能用普通用户。
[root @localhost pgsql]# adduser postgres
[root @localhost pgsql]# chown -R postgres /usr/local/pgsql/data/
初始化数据库：
[root @localhost pgsql]# su postgres
[postgres @localhost pgsql]$ ./bin/initdb -D /usr/local/pgsql/data/
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.UTF-8.
The default database encoding has accordingly been set to UTF8.

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:

./bin/postgres -D /usr/local/pgsql/data
or
./bin/pg_ctl -D /usr/local/pgsql/data -l logfile start

用POSTGRES用户启动PGsql服务进程
/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data >logfile 2>&1 &
实际操作
也可以这样启动PGsql服务进程
/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data -l /usr/local/pgsql/logfile start
做成服务自动启动
[root@localhost start-scripts]# cp /usr/local/pgsql/contrib/start-scripts/linux /etc/init.d/pgsql
[root@localhost start-scripts]# chkconfig --add pgsql
[root@localhost start-scripts]# service pgsql status
pg_ctl: server is running (PID: 7019)
/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data
[root@localhost start-scripts]# export PATH=$PATH:/usr/local/pgsql/bin/
[postgres @localhost ~]$ createdb t_girl

[postgres @localhost ~]$ psql t_girl
