14、/share/mysql/my-f /etc/f3. 修改fvi /etc/f在client下添加default-character-set=utf8在mysqld下添加default-character-set=utf84.重新啟動MySQL rootbogon # /etc/rc.d/init.d/mysql restartShutting down MySQL                           

15、;               確定 Starting MySQL.                                              確定 rootbogon # mysql

16、 -u root -pEnter password:Welcome to the MySQL monitor. Commands end with ; or g.Your MySQL connection id is 1Server version: 5.1.22-rc-community-log MySQL Community Edition (GPL)Type 'help;' or 'h' for help. Type 'c' to clear the buffer.5.查看字符集設置mysql> show variables like
