想看详细介绍请看官方文档 : http://www.postgres.cn/docs/9.5/install-procedure.html

1. 安装：
[root@mysqltest1 postgresql-10.1]# ./configure --prefix=/usr/local/pgsql
......
configure: error: in `/usr/local/postgresql-10.1':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
​
缺少 gcc包， 安装gcc包
[root@mysqltest1 postgresql-10.1]# yum -y install gcc

configure: error: readline library not found</span>

据提示，应该是没有安装 readline包。

3 检查系统是否安装 readline 包
[root@mysqltest1 postgresql-10.1]# rpm -qa | grep readline
readline-6.2-10.el7.x86_64</span>

4 通过 yum 搜索相关的readline 包
[root@mysqltest1 postgresql-10.1]# yum search readline

readline.x86_64 : A library for editing typed command lines

5. 安装 readline-devel 包
[root@mysqltest1 postgresql-10.1]# yum -y install -y readline-devel

6.编译安装
make 编译
make install 安装

7.配置共享库：
LD_LIBRARY_PATH=/usr/local/pgsql/lib
export LD_LIBRARY_PATH</span>

8. 环境变量

[root@mysqltest1 pgsql]# su - pgsql
[root@mysqltest1 pgsql]# vim .bash_profile
​
export PGHOME=/usr/local/pgsql  
export PGDATA=/usr/local/pgsql/data  
export PGLIB=/usr/local/pgsql/lib  
export PATH=$PGHOME/bin:$PATH  
​
source /home/pgsql/.bash_profile

9.查看环境变量是否生效

[root@mysqltest1 /]# psql -V
psql (PostgreSQL) 10.1

9. 创建用户,跟oracle一样，pgsql需要单独创建一个用户进行管理

useradd pgsql
chown pgsql:pgsql /usr/local/pgsql -R

10. 初始化数据库
由于配置了环境变量，所以此处我们直接执行initdb即可完成db初始化，但在这之前可以通过initdb --help看一下初始化相关的帮助信息：

初始化
initdb -D /usr/local/pgsql/data/

启动服务
pg_ctl -D /usr/local/pgsql/data/ -l /usr/local/pgsql/logs/logfile start

11.启动失败，log文件报错信息：

could not open lock file "/tmp/.s.PGSQL.5432.lock": 权限不够

解决办法：
chown pgsql:pgsql /tmp/.s.PGSQL.5432.lock

12.创建数据库
[pgsql@mysqltest1 data]$ createdb mydb
[pgsql@mysqltest1 data]$ dropdb mydb

13. 访问数据库：

[pgsql@mysqltest1 data]$ psql mydb
psql (10.1)
Type "help" for help.
mydb=#

14. 查看版本
mydb=# select version();'

                                              version
