安装PGSQL
PGSQL源码地址：https://ftp.postgresql.org/pub/source/
下载9.0版本源码
[root@localhost soft]# wget https://ftp.postgresql.org/pub/source/v9.0.0/postgresql-9.0.0.tar.gz --no-check-certificate解压源码并进入解压目录
[root@localhost soft]# tar -zxvf postgresql-9.0.0.tar.gz
[root@localhost soft]# cd postgresql-9.0.0配置编译安装包含插件
[root@localhost postgresql-9.0.0]# ./configure --prefix /data/programs/PostgreSQL/9.0 CFLAGS="-Wno-aggressive-loop-optimizations"
[root@localhost postgresql-9.0.0]# make world
[root@localhost postgresql-9.0.0]# make install-world 
进入安装目录
[root@localhost postgresql-9.0.0]# cd /data/programs/PostgreSQL/9.0/ 
添加postgres用户组及用户
[root@localhost 9.0]# groupadd postgres
[root@localhost 9.0]# useradd -g postgres postgres创建数据存储目录
[root@localhost 9.0]# mkdir /data/programs/PostgreSQL/9.0/data修改数据存储目录权限
[root@localhost 9.0]# chown postgres:postgres /data/programs/PostgreSQL/9.0/data中文环境设置
#临时修改(当前终端生效)：
export LANG="zh_CN.UTF-8"
#永久修改：
echo "export LANG=zh_CN.UTF-8" >> /etc/profile
source /etc/profile
切换postgres用户
[root@localhost 9.0]# su postgres
#如果出现 bash: /home/postgres/.bashrc: Permission denied
#使用root用户，设置home目录权限
[root@localhost 9.0]# chmod 77 /home/postgres初始化data目录
[postgres@localhost 9.0]$ /data/programs/PostgreSQL/9.0/bin/initdb --pgdata /data/programs/PostgreSQL/9.0/data --encoding=UTF8 --lc-collate=zh_CN.utf8 --lc-ctype=zh_CN.utf8 --lc-messages=zh_CN.utf8 --lc-monetary=zh_CN.utf8 --lc-numeric=zh_CN.utf8 --lc-time=zh_CN.utf8
启动pgsql服务
[postgres@localhost 9.0]$ /data/programs/PostgreSQL/9.0/bin/pg_ctl --pgdata /data/programs/PostgreSQL/9.0/data start
停止pgsql服务
[postgres@localhost 9.0]$ /data/programs/PostgreSQL/9.0/bin/pg_ctl --pgdata /data/programs/PostgreSQL/9.0/data stop
使用service启动
拷贝文件
[root@localhost 9.0]# cp /data/soft/postgresql-9.0.0/contrib/start-scripts/linux /etc/init.d/postgresql-9.0赋予执行权限
[root@localhost 9.0]# chmod +x /etc/init.d/postgresql-9.0编辑文件
创建log目录
[root@localhost 9.0]# mkdir /data/programs/PostgreSQL/9.0/data/pg_log启动服务
[root@localhost 9.0]# service postgresql-9.0 start
配置网络访问
[root@localhost 9.0]# vim /data/programs/PostgreSQL/9.0/data/postgresql.conf
配置错误日志
[root@localhost 9.0]# vim /data/programs/PostgreSQL/9.0/data/postgresql.conf
添加密码访问
[root@localhost 9.0]# vim /data/programs/PostgreSQL/9.0/data/pg_hba.conf
修改配置需要重启服务
[root@localhost 9.0]# service postgresql-9.0 restart修改密码，用户名postgres
[postgres@localhost bin]$ /data/programs/PostgreSQL/9.0/bin/psql
安装过程中的错误处理
错误信息：
configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.
安装readline
[root@localhost postgresql-9.0.0]# yum install readline readline-devel -y
错误信息：
configure: error: zlib library not found
If you have zlib already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-zlib to disable zlib support.
安装zlib
[root@localhost postgresql-9.0.0]# yum install zlib zlib-devel -y
错误信息：
initializing pg_authid ... FATAL: wrong number of index expressions
STATEMENT: REVOKE ALL on pg_authid FROM public;
child process exited with exit code 1
gcc版本过高。高版本的gcc采用了更激进的循环上界分析推导算法。但这会导致一些旧的程序运行出错。在数据库编译安装进行configure操作时，添加参数"-Wno-aggressive-loop-optimizations"或"-fno-aggressive-loop-optimizations"。
