# 1.1 问题显示 #

[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

    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
