下面是pg_ctl命令的使用方法和常用选项,需要指出的是,该命令是postgres命令的封装体,,因此在使用上比直接使用postgres更加方便。
pg_ctl init[db] [-D DATADIR] [-s] [-o "OPTIONS"]
pg_ctl start [-w] [-t SECS] [-D DATADIR] [-s] [-l FILENAME] [-o "OPTIONS"]
pg_ctl stop [-W] [-t SECS] [-D DATADIR] [-s] [-m SHUTDOWN-MODE]
pg_ctl restart [-w] [-t SECS] [-D DATADIR] [-s] [-m SHUTDOWN-MODE]
pg_ctl reload [-D DATADIR] [-s]
pg_ctl status [-D DATADIR]
pg_ctl promote [-D DATADIR] [-s]
选项 描述
-D 指定数据库存储的路径
-l 指定服务器进程的日志文件
-s 仅打印错误信息,不打印普通信息
-t SECS 当使用-w选项时等待的秒数
-w 等待直到数据库操作完成(对于stop而言,该选项时缺省选项)
-W 不等待任何操作的完成
--help 显示帮助信息
--version 显示版本信息
-m 对于stop和restart操作,可以指定关闭模式
系统关闭模式
smart 不在接收新的连接,直到当前已有的连接都断开之后才退出系统
fast 不在接收新的连接请求,主动关闭已经建立的连接,之后退出系统
immediate 立即退出,但是在restart的时候需要有恢复的操作被执行
这里我们只是给出最为常用的使用方式,即数据库服务器的正常启动和关闭。
#start表示启动postgres服务器进程。
#-D指定数据库服务器的初始目录的存放路径。
#-l指定数据库服务器进程的日志文件
/> pg_ctl -w start -D /opt/PostgreSQL/9.1/data -l /opt/PostgreSQL/9.1/data/pg_log/startup.log
#stop表示停止postgres服务器进程
#-m fast在关闭系统时,使用fast的关闭模式。
/> pg_ctl stop -m fast -w -D /opt/PostgreSQL/9.1/data
