一，卸载自带mysql，删除MySQL的lib库，服务文件
[root@localhost ~]# yum remove mysql mysql-server mysql-libs
[root@localhost ~]# rpm -ev MySQL-server-5.0.22-0.i386
[root@localhost ~]# rpm -ev MySQL-client-5.0.22-0.i386
清除所有mysql相关文件：
[root@localhost ~]#find / -name mysql
[root@localhost ~]#rm -rf 文件或者文件夹
查看是否有残留文件：
[root@localhost ~]#rpm -qa | grep -i mysql
执行命令卸载MySQL相关的文件
[root@localhost ~]# yum -y remove MySQL*
二，安装MySQL
1.复制mysql安装包到安装目录
[root@localhost opt]# mkdir mysql [root@localhost opt]# cp /home/duke147/Desktop/Tools/MySQL-5.6.22-1.linux_glibc2.5.i386.rpm-bundle.tar /opt/mysql/ [root@localhost opt]# cd mysql/ [root@localhost mysql]# ls -a . .. MySQL-5.6.22-1.linux_glibc2.5.i386.rpm-bundle.tar
[root@localhost mysql]# tar xvf MySQL-5.6.22-1.linux_glibc2.5.i386.rpm-bundle.tar MySQL-test-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL的测试组件 MySQL-shared-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL的共享库 MySQL-shared-compat-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL版本兼容的包 MySQL-client-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL客户端程序 MySQL-devel-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL的库和头文件 MySQL-embedded-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL的嵌入式程序 MySQL-server-5.6.22-1.linux_glibc2.5.i386.rpm #MySQL服务端程序

See the manual for the semantics of the 'password expired' flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database. This is strongly recommended for production servers.
