登录MySQL的命令是mysql, mysql 的使用语法如下:
mysql [-u username] [-h host] [-p[password]] [dbname]
username 与 password 分别是 MySQL 的用户名与密码,mysql的初始管理帐号是root,没有密码,注意:这个root用户不是Linux的系统用户。MySQL默认用户是root,由于初始没有密码,第一次进时只需键入mysql即可。
然后输入mysql
root@test1 local]# mysql
Welcome to the MySQL monitor. Commands end with ; or /g.
Your MySQL connection id is 1 to server version: 4.0.16-standard
Type 'help;' or '/h' for help. Type '/c' to clear the buffer.
mysql>
出现了“mysql>”提示符,恭喜你,安装成功!
修改登录密码
MySQL默认没有密码,安装完毕增加密码的重要性是不言而喻的。
1、命令
usr/bin/mysqladmin -u root password 'new-password'
格式:mysqladmin -u用户名 -p旧密码 password 新密码
键入以下命令 :
[root@test1 local]# /usr/bin/mysqladmin -u root password 123456
注:因为开始时root没有密码,所以-p旧密码一项就可以省略了
