[root@localhost ~]# mysql -uroot -p1234567
mysql: [Warning] Using a password on the command line interface can be insecure.

1.2 解决方法

1.2.1 方法一

1、将密码写入到主配置文件中

[root@localhost ~]# vim /etc/my.cnf
[mysqldump]
user=root
password=1234567

[mysql]
user=root
password=1234567

2、直接使用命令登录，再也无需输入账号密码

[root@localhost ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 10
Server version: 5.7.18-log Source distribution

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
mysql> 

1.2.2 方法二

1、自动配置MYSQL密文密码

该操作会在用户家目录下生成一个隐藏文件".mylogin.cnf"，里面记录了MYSQL的密文的密码，只要配置了以后，我们也是直接使用命令登录，再也无需输入账号密码了，如果你想取消，删除此文件即可。

[root@localhost ~]# mysql_config_editor set --user=root --host=localhost --port=3306 --password
Enter password: 输入密码

2、直接使用命令登录，再也无需输入账号密码

[root@localhost ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 11
Server version: 5.7.18-log Source distribution

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
mysql> 

1.2.3 方法三

1、直接使用命令登录，屏蔽错误信息

由于告警信息是标准错误，我们可以将标准错误的输出信息输出为空。

[root@localhost ~]# mysql -uroot -p1234567 2>/dev/null
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 36

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.
