安装lnmp集成环境

具体配置看原文，不重新复述：

原文：https://lnmp.org/install.html

因为配置数据库主从，需要保持两台mysql数据库服务器的mysql版本号一致，所以又重新装了一次。。重新安装直接操作步骤2即可。貌似没卸载，直接重装就行。

1、参考原文

yum install screen

2、参考原文

wget -c http://soft.vpser.net/lnmp/lnmp1.3-full.tar.gz && tar zxf lnmp1.3-full.tar.gz && cd lnmp1.3-full && ./install.sh lnmp

最后出现这个：按回车（大概30分钟多点）

3、个人觉得到这一步之后，可以不用再参考原文。

直接访问 http://ip 或者命令行 curl http://localhost/

用集成包，只是嫌麻烦一个一个安装，到这一步之后，什么配置虚拟机啥的，用到再配置就可以了。

4、在配置主从的时候，关不掉mysql。（可能因为重新安装了lnmp集成包，原先的进程没有停掉，改了myslq的版本安装，找不到mysql的进程号了）

/etc/init.d/mysql stop

但是关闭mysql的时候报错了：

MySQL server PID file could not be found!                  [FAILED]

解决办法： 原文出处：http://www.longhui.org/archives/466

ps aux|grep mysql

找出Mysql的进程，然后杀掉。 Kill 进程号

kill 1111

然后启动Mysql：

/etc/init.d/mysql strat
