MYSQL命令行输入密码警告问题"mysql: [Warning]"解决
一、问题
[root@localhost ~]# mysql -uroot -p1234567
mysql: [Warning] Using a password on the command line interface can be insecure.
二、解决方法
1. 方法一
-
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
-
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.

2. 方法二
-
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
