本以为很顺利的就能装完了。


mysql的安装包 64位，5.6.20的

http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.20-1.el6.x86_64.rpm



http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.20-1.el6.x86_64.rpm


http://cdn.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.20-1.el6.x86_64.rpm


安装rpm -ivh MySQL-server-5.6.20-1.el6.x86_64.rpm

然后就提示


 file /usr/mysql/czech/errmsg.sys from install of MySQL-server-5.6.20-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.73-3.el6_5.x86_64

一堆冲突，解决办法如下：

yum -y remove mysql-libs-5.1.73*


装好了之后，准备修改密码



A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !

You will find that password in '/root/.mysql_secret'.



vi /root/.mysql_secret 就可以看到里面的密码了。


登录之后，然后修改密码即可。


mysql -u root -p


 SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456') 


以上的命令是将root的密码改为123456


常用命令：

service mysql start 或者 /etc/init.d/mysql start 启动

service mysql stop   或者/etc/init.d/mysql stop  停止

service mysql restart  或者 /etc/init.d/mysql restart 重启
