1、首先安装依赖包，避免在安装过程中出现问题
shell> yum install gcc gcc-c++ automake autoconf libtool make
shell> yum install readline-devel
shell> yum install zlib-devel
2、创建postgre用户及用户组
shell> groupadd postgre
shell> useradd -g postgre postgre
shell> passwd postgre #修改密码
shell> id postgre
uid=500(postgre) gid=501(postgre) 组=501(postgre)
3、编译安装postgre
shell> tar zxvf postgresql-9.3.6.tar.gz
shell> cd postgresql-9.3.6
shell> ./configure --prefix=/db/pgsql
shell> make && make install
PostgreSQL installation complete.
4、设置数据库目录权限并初始化数据库
shell> mkdir -p /db/pgsql/data
shell> chown -R postgre.postgre /db/pgsql/
shell> cp contrib/start-scripts/linux /etc/rc.d/init.d/postgresql
shell> su - postgre
# 初始化数据库
shell> /db/pgsql/bin/initdb -D /db/pgsql/data/
The files belonging to this database system will be owned by user "postgre".
This user must also own the server process.
The database cluster will be initialized with locale "zh_CN.UTF-8".
The default database encoding has accordingly been set to "UTF8".
initdb: could not find suitable text search configuration for locale "zh_CN.UTF-8"
The default text search configuration will be set to "simple".
Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
/db/pgsql/bin/postgres -D /db/pgsql/data/
or
/db/pgsql/bin/pg_ctl -D /db/pgsql/data/ -l logfile start
5、设置环境变量
shell> vi .bash_profile
==================================================================
PATH=$PATH:$HOME/bin:/db/pgsql/bin
export PGDATA=/db/pgsql/data
export PGHOME=/db/pgsql
export LANG=zh_CN.UTF-8
export PGPORT=5432
export PATH
==================================================================
shell> source .bash_profile
6、开启postgre服务
shell> pg_ctl -D /db/pgsql/data/ -l /db/pgsql/log/logfile start
server starting
shell> tail -f /db/pgsql/logfile
LOG: database system was shut down at 2015-04-20 17:59:36 CST
LOG: database system is ready to accept connections
LOG: autovacuum launcher started
7、测试连接数据库
shell> createdb mydb
shell> psql -h 127.0.0.1 -p 5432 -U postgre -W mydb
Password for user postgre:
psql (9.3.6)
Type "help" for help.
mydb=#
# 显示当前数据库
mydb=# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+---------+----------+-------------+-------------+---------------------
mydb | postgre | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 |

template0 | postgre | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/postgre +
| | | | | postgre=CTc/postgre
template1 | postgre | UTF8 | zh_CN.UTF-8 | zh_CN.UTF-8 | =c/postgre +
| | | | | postgre=CTc/postgre
