然后选择：
把下载好的安装包传到服务器上的指定目录，然后解压：
[root@master mysql]# tar -xvf mysql-5.7.24-1.el6.x86_64.rpm-bundle.tar
mysql-community-test-5.7.24-1.el6.x86_64.rpm
mysql-community-client-5.7.24-1.el6.x86_64.rpm
mysql-community-libs-compat-5.7.24-1.el6.x86_64.rpm
mysql-community-libs-5.7.24-1.el6.x86_64.rpm
mysql-community-server-5.7.24-1.el6.x86_64.rpm
mysql-community-devel-5.7.24-1.el6.x86_64.rpm
mysql-community-embedded-5.7.24-1.el6.x86_64.rpm
mysql-community-embedded-devel-5.7.24-1.el6.x86_64.rpm
mysql-community-common-5.7.24-1.el6.x86_64.rpm
查询有没有安装MySQL：
rpm -qa | grep mysql
如果安装，则卸载：
rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64
安装下面的顺序进行安装：
rpm -ivh mysql-community-common-5.7.24-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.24-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.24-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.24-1.el6.x86_64.rpm
rpm -ivh mysql-community-server-5.7.24-1.el6.x86_64.rpm
然后启动：
service mysqld start
查看报错日志：
grep ‘temporary password‘ /var/log/mysqld.log
2019-01-04T18:41:22.901300Z 1 [Note] A temporary password is generated for root@localhost: wsOk8mlgky*.
mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (2)
ps -A | grep -i mysql
查看状态：
/etc/rc.d/init.d/mysqld status
mysqld is stopped
重启：
service mysqld start
Starting mysqld: [ OK ]
再次查看：
/etc/rc.d/init.d/mysqld status
mysqld (pid 2748) is running...
进入MySQL：
mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user ‘root‘@‘localhost‘ (using password: YES)
报错:
修改：vim /etc/my.cnf
添加：
[mysqld]
skip-grant-tables
重新启动：/etc/init.d/mysqld restart
Stopping mysqld: [ OK ]
/usr/bin/mysqld_safe: line 517: cd: /root/mysql/mysql5.7: Not a directory
Starting mysqld: [ OK ]
[root@master mysql5.7]# mysql

可以看到中间有个报错：
/usr/bin/mysqld_safe: line 517: cd: /root/mysql/mysql5.7: Not a directory
解决办法：
chmod -R 755 /root
[root@master /]# /etc/init.d/mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
完美解决。

至此，MySQL安装成功。
