make && make install##这个编译过程时间需要一个小时左右
##在make install阶段如果出现很多红色的字体，并且界面卡住了，可以直接ctrl +C中断安装状态，重新执行make install即可
重新编译时,需要清除旧的对象文件和缓存信息
make clean
rm -f CmakeCache.txt
然后再继续camak，make && make install
cd /usr/local/lnmp/mysql/bin
[root@server2 bin]# vim ~/.bash_profile

[root@server2 support-files]# rpm -e `rpm -qa | grep mysql` --nodeps

说明：由于本机之前安装过mysql 所以源码安装的时候需要清除环境影响
这里还不能直接yum remove。yum remove会把软件的依赖性一起删除，并且会导致postfix等服务启动出现故障。
