Xshell怎么连接数据库

root@VM-0-12-centos[14:05:47]:~ 2 $ mysql -h ** -u ** -p 3 Enter password: 4 Welcome to the MySQL monitor. Commands end with ; or \g. 5 Your MySQL connection id is 52674 6 Server version: 5.6.25 Source distribution 7 8 Copyright (c) 2000, 2021, Oracle and/or its affiliates.

这样就表示连接上了。里面输入SQL语句就和MySQL一样使用，注意SQL语句的结尾分号“;”必须有！，否则会报错。

出现中文乱码问题，可以用以下命令临时解决，为什么是临时解决？重新登入后还是有有乱码问题。表格没有对齐—现在各大网站还没有更好的解决方案。

1 mysql> set names utf8;
2 Query OK, 0 rows affected (0.03 sec)

今天先寄这些，后面再更。
