(1)服务器配置：
[root@localhost ~]# cd /usr/local/src/[root@localhost src]# wget http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm [root@localhost src]# rpm -ivh mysql57-community-release-el7-8.noarch.rpm """mysql-community-client-5.7.30-1.el7.x86_64.rpm mysql-community-server-5.7.31-1.el7.x86_64.rpm"""将这两个个rpm包，以FTP形式导入：/var/cache/yum/x86_64/7/mysql57-community/packages/[root@localhost src]# yum -y install mysql-server等待时间较长
(2)重置密码与创建用户
#重启mysql服务[root@VM-0-3-centos src]# service mysqld restart#重置密码[root@localhost ~]# grep "password" /var/log/mysqld.log
#密码重置mysql> alter user 'root'@'localhost' identified by 'password';//密码重置，新的密码Query OK, 0 rows affected (0.00 sec)#创建新的用户，mysql> create user 'username'@'%' identified by 'paswword';//添加新的用户，密码Query OK, 0 rows affected (0.00 sec)#给新用户分权限mysql> grant all privileges on *.* to 'user1'@'%' with grant option; Query OK, 0 rows affected (0.00 sec) #刷新权限 mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)Query OK, 0 rows affected (0.00 sec)
#刷新权限
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
(3)查询MySql当前用户：
mysql> select user,host from mysql.user;+---------------+-----------+| user | host |+---------------+-----------+| user1 | % || mysql.session | localhost || mysql.sys | localhost || root | localhost |+---------------+-----------+4 rows in set (0.00 sec)mysql>(4)实现在Navicat上连接
