MySQL學習——mysql登陸命令

一、以Windows系統爲例，經過cmd命令行登陸mysql數據庫的命令爲：

　　mysql　-p(password)　-u(username) 　-h(service IP)

登陸提示：

　　[Warning] Using a password on the command line interface can be insecure.

[警告]直接在命令行使用明碼密碼是不安全的

　　推薦使用命令mysql -p -u(username) -h(service IP)；先不直接輸入密碼，提示Enter password，再輸入密碼，能夠借竟然以上問題。

 

成功登陸mysql以後，提示以下：

Welcome to the MySQL monitor. Commands end with ; or \g.[提示：mysql命令以;或者\g爲結束符]
