bitsCN.comSQL学习笔记——SQL初入门,Ubuntu下MySQL的安装
刚开始接触sql,于是准备在Ubuntu下学习sql,就跟着itercast的sql教程开始入门了。
下面只是我个人的记录,高手请绕道:
一、
在安装之前,我们可以用下面这个命令通过开放端口查询来看看是否有mysql服务在运行。
当然在安装完后也可以用这个查看是否在运行。
[plain]
$ netstat -tap|grep mysql
如果在运行的话会看到
[plain]
tcp 0 0 localhost:mysql *:*
二、
用apt-get即可安装:
[plain]
$ sudo apt-get install mysql-server mysql-client
途中会跳出窗口要求输入密码,这个就是mysql的root用户的密码
三、
进入mysql:
[plain]
$ mysql -u root -p
输入刚才的密码即可登录进去
四、
开关mysql服务
[plain]
sudo start mysql
sudo stop mysql
mysql的配置文件:
/etc/mysql/my.cnf
在里面可以修改mysql的端口、数据库保存路径等信息
