1、确认mysql是否已安装，有下面的代码可知
| [root@cdh1 zjl]# yum list installed mysql*Loaded plugins: fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.comInstalled PackagesMySQL-python.x86_64 1.2.3-0.3.c1.1.el6 @base mysql-libs.x86_64 5.1.73-8.el6_8 @anaconda-CentOS-201703281317.x86_64/6.9 |
2、卸载已安装的mysql，建议使用yum命令，因为yum命令可以自动删除与mysql相关的依赖；如果使用rpm命令，则还需要手动去删除和mysql相关的文件，比较麻烦
