ubuntu安装mysql后的配置

1,备份 /etc/mysql/my.cnf

sudo cp /etc/mysql/my.cnf /etc/mysql/my.cnf.bak

2.编辑my.cnf

sudo vi /etc/mysql/my.cnf

大约47行

#bind-address = 127.0.0.1

加#注释掉 否则不能远程登录

[mysqld]里添加一行

character_set-server=utf8 (这里特别注意，老版本的是设置 default-character-set=utf8 然后服务无法启动)

设置mysql默认编码方式，默认的latin1不支持中文

这两项改完后 sudo /etc/init.d/mysql restart 重启服务，登录mysql 通过 status查看编码是否修改成功。

3.取消开机启动

由于不是每次开机都需要用到mysql，服务自启动浪费资源，改为手动管理mysql服务。

zhh@itant:/etc/init.d$ sudo service mysql stop
mysql stop/waiting
zhh@itant:/etc/init.d$ sudo update-rc.d -f mysql remove
 Removing any system startup links for /etc/init.d/mysql ...
zhh@itant:/etc/init.d$ sudo service mysql start
mysql start/running, process 5186
zhh@itant:/etc/init.d$ mysql -u root -p
Enter password:

zhh@itant:/etc/init.d$

4.安装python-mysql

下载mysql-python 进入mysql-python目录，python install.py install 安装

提示 mysql_config not found，执行 sudo apt-get install libmysqld-dev 然后 sudo find / -name mysql_config 将查到的路径 编辑到 site.cfg中。

提示 _mysql.c:29:20: 致命错误： Python.h：没有那个文件或目录 ，执行 sudo apt-get install python-dev

最后执行安装命令

sudo python setup.py build

sudo python setup.py install

测试： python->import MySQLdb
