Mysql 5.7.18 uses MySQL proxies_priv to achieve similar user group management instance sharing

This article mainly introduces in detail how MySQL 5.7.18 uses MySQL proxies_priv to achieve similar user group management. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

Use MySQL proxies_priv (simulated role) to achieve similar user group management

Role (Role) can be used to manage users in batches. Users under the same role have the same permissions.

After MySQL5.7.

##

mysql> show variables like "%proxy%"; #查看当前proxy是否开启，下图表示没有开启

##

mysql> set global check_proxy_users =on; #开启proxy 下图表示已开启
mysql> set global mysql_native_password_proxy_users = on;

mysql> exit
Bye #以上设置参数，对当前会话无效，需要退出后重新登录，或直接设置到my.cnf中去

2. Create user

mysql> create user will_dba; #类似组
mysql> create user 'will';
mysql> create user 'tom'; 
#密码就不设置了，如需设置密码后面加上identified by '123'

3. Map the permissions of will_dba to will,tom

mysql> grant proxy on will_dba to will;
mysql> grant proxy on will_dba to tom;

4. Grant actual permissions to will_dba (simulated Role)

mysql> grant select on *.* to will_dba;

5. View will_dba Permissions

mysql> show grants for will_dba;

6. View the permissions of will and tom

mysql> show grants for will;

##

mysql> show grants for tom;

7. View the permissions of proxies_priv

mysql> mysql> select * from mysql.proxies_priv;

8. Verification

Use will and tom users to view the database

[root@test-1 ~]# mysql -utom -p
mysql> show databases; #tom用户我们之前没有赋予权限，但这里可以查看
mysql> show tables;
mysql> select * from user\G

##mysql.proxies_priv is just a simulation of Role , and the role of Oracle is still different. The official name is Role like

MySQL5.6.X needs to install a plug-in to simulate the Role function. For specific methods, please refer to:
