Detecting whether the system has been installed mysql or dependence, which was first installed over Ruoyi deleted, otherwise Step 4 will get an error with yum:
[root@mysql01 Packages]# yum list installed |grep mysql
mysql-libs.x86_64 5.1.73-5.el6_6 @anaconda-CentOS-201508042137.x86_64/6.7
[root@mysql01 Packages]# yum -y remove mysql-libs.x86_64
1. create a package storage location
mkdir / soft
2. Edit the configuration file
vim /etc/my.cnf
3. Extract the binary distribution
tar -xzvf mysql-5.7.24-linux- glibc2.12-x86_64.tar.gz
