(1)伺服器配置：

[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
"""
將這兩個個rpm包，以FTP形式匯入：/var/cache/yum/x86_64/7/mysql57-community/packages/

[root@localhost src]# yum -y install mysql-server

等待時間較長

(2)重置密碼與建立使用者

#重啟mysql服務
[root@VM-0-3-centos src]# service mysqld restart

#重置密碼
[root@localhost ~]# grep "password" /var/log/mysqld.log

#密碼重置mysql> alter user 'root'@'localhost' identified by 'password';//密碼重置，新的密碼
Query OK,0 rows affected (0.00 sec)

#建立新的使用者，
mysql> create user 'username'@'%' identified by 'paswword';//新增新的使用者，密碼
Query OK,0 rows affected (0.00 sec)#給新使用者分許可權mysql> grant all privileges on *.* to 'user1'@'%' with grant option;
 Query OK,0 rows affected (0.00 sec)
 #重新整理許可權
 mysql> flush privileges;
 Query OK,0 rows affected (0.00 sec)

Query OK,0 rows affected (0.00 sec)

#重新整理許可權

mysql> flush privileges;

Query OK,0 rows affected (0.00 sec)

(3)查詢MySql當前使用者：

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)實現在Navicat上連線
