Centos 6.9 detailed tutorial on installing mysql, centosmysql

1. Check whether mysql is installed. See the following code.

[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. Uninstall installed mysql. We recommend that you use the yum command because the yum command can automatically delete mysql-related dependencies. If you use the rpm command, you also need to manually delete mysql-related files.

3. Run the whereis command to find mysql-related files. Because step 2 is uninstalled using yum, mysql is cleaned up. If rpm is used, it will be very troublesome, many files need to be manually cleared.

[root@cdh1 zjl]# whereis mysqlmysql:

4. view the mysql installation package in the system
