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

10 PATH=$PATH:$HOME/bin:/usr/local/lnmp/mysql/bin#这样就能自动补齐

[root@server2 bin]# source ~/.bash_profile#刷新，立即生效

[root@server2 bin]# cd ..

[root@server2 mysql]# cd support-files/

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

warning: /var/log/mysqld.log saved as /var/log/mysqld.log.rpmsave

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。

[root@server2 support-files]# yum install mysql-libs -y

[root@server2 support-files]# yum check

[root@server2 support-files]# /etc/init.d/postfix restart#检测是否排除上文提及的问题

关闭 postfix：                                             [确定]

启动 postfix：                                             [确定]

##mysql_install_db这个命令是不被认同的，让我们用mysqld --initialize这个命令
