linux登陆mysql数据库

mysql登录的方式是这样的：

[root@crmtestdb root]#mysql -u root -h 127.0.0.1
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 3
Server version: 5.0.45-community MySQL Community Edition (GPL)

Type ''help;'' or ''\h'' for help. Type ''\c'' to clear the buffer.

mysql>

 

如果有密码的话，登录方式为：

 mysql -u root -h 127.0.0.1 -p

至于该使用哪个数据库，使用哪个，应该是这样：

mysql> show databases;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| mysql              |

| test               |

| wt                 |

+--------------------+

4 rows in set (0.00 sec)

mysql> use test

Database changed

mysql>
