(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
