SUSE11 安装mysql
SUSE11检测系统是否安装MySQL
#rpm -qa | grep -i mysql 若已安装过，会出现：
MySQL-server-5.0.22-0.i386
MySQL-client-5.0.22-0.i386
那么输入以下命令删除它：
#rpm -ev MySQL-server-5.0.22-0.i386
# rpm -ev MySQL-client-5.0.22-0.i386
注意：若删除的时候，出现删除不成功，出现依赖的包，前提必须删除依赖项。rpm -ev dovecot-1.0.7-7.el5.x86_64
在suse11.2-64上先安装一个本地库： 用国内镜像，注意mysql 5.6.22 由于版本更新，所以可以直接访问http://mirrors.sohu.com/mysql/MySQL-5.6/ 查看新的版本，否则wget 下载不到需要的rpm文件.
wget -chttp://mirrors.sohu.com/mysql/MySQL-5.6/MySQL-server-5.6.22-1.sles11.x86_64.rpm (for suse11-64版本)
wget -chttp://mirrors.sohu.com/mysql/MySQL-5.6/MySQL-client-5.6.22-1.sles11.x86_64.rpm
wget -chttp://mirrors.sohu.com/mysql/MySQL-5.6/MySQL-devel-5.6.22-1.sles11.x86_64.rpm
下载完成后开始安装：
rpm -ivh MySQL-server-5.6.22-1.sles11.x86_64.rpm MySQL-client-5.6.22-1.sles11.x86_64.rpm MySQL-devel-5.6.22-1.sles11.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
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.
See the manual for more instructions.
