[root@typecodes ~]# yum -y install mysql-community-develAppendix 3: Deleting MySQL's RepositoryBecause MySQL's Yum Repository was installed in Section 3, every time a yum operation is performed in the future, updates will be checked. If you want to remove this automatic checking operation, you can use the following command to uninstall the MySQL Repository.
[root@typecodes ~]# yum -y remove mysql57-community-release-el7-7.noarch update 2017.04.10 11:10Using the above yum method, you can also install the latest version mysql5.7.18 currently on the mysql official website. Just replace the version of the rmp package in Section 2, and the subsequent steps remain unchanged.
