标签：ant tables 修改 tin 因此 strong expired cli 用户信息
MySQL 5.5一般可以通过修改改参数来（基线默认是1），debug mysql.err中记录warning，note信息，如果应用端连接数据库由于用户密码异常可以在my.err中记录用户连接失败的提示信息，且多次连接失败会出现连接失败报警。修改方式：
set global log_warnings=2;
MySQL 5.5版本官方文档中，并没有用户锁的状态。因此不存在用户会被锁。。
The account-locking capability depends on the presence of the account_locked column in the
mysql.user table. For upgrades to MySQL 5.7.6 and later from older versions, run mysql_upgrade
to ensure that this column exists. For nonupgraded installations that have no account_locked
column, the server treats all accounts as unlocked, and using the ACCOUNT LOCK or ACCOUNT
UNLOCK clauses produces an error.

可以通过如下方式查看用户锁状态、但都仅限MySQL 5.7.6以上
mysql> show create user ‘root‘;

| CREATE USER for root@% |
+-------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| CREATE USER ‘root‘@‘%‘ IDENTIFIED WITH ‘mysql_native_password‘ AS ‘*D61994AAB9327E97C4BECC73E497951CFC723C99‘ REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
