ubuntu下安裝設置mysql

1、安裝：

apt-get install mysql-server

2、設置允許遠程登錄

  修改/etc/mysql/my.cnf(此文件爲mysql的配置文件)。將文件中的binding-address=127.0.0.1註釋掉。

  從本機登陸mysql：mysql -u root -p

  use mysql;

  設置允許所有主機連接到Mysql，執行命令:grant all privileges on *.* to root@"%" identified by "root用戶的密碼" with grant option;

3、重啓mysql

  /etc/init.d/mysql restart

*注：/etc/init.d/mysql start|stop|restart可以啓動/停止/重啓

4、設置開機自啓動

把啓動命令（/etc/init.d/mysql start）加入/etc/rc.local文件中

5、設置Mysql字符集：

創建數據庫時指定字符集：create database mydb character set utf-8;

查看當前字符集：show variables like 'character%';

修改當前數據庫的字符集：

mysql> SET character_set_client = utf8 ;
mysql> SET character_set_connection = utf8 ;
mysql> SET character_set_database = utf8 ;
mysql> SET character_set_results = utf8 ;
mysql> SET character_set_server = utf8 ;
mysql> SET NAMES utf8; //這條語句會改變  character_set_client  character_connection   character_results這三個 的字符集
