默认登录mysql之后show variables like ‘%character%’, 出现

  mysql》 show variables like ‘%character%’;

  +--------------------------+----------------------------+

  | Variable_name | Value |

  +--------------------------+----------------------------+

  | character_set_client | latin1 |

  | character_set_connection | latin1 |

  | character_set_database | latin1 |

  | character_set_filesystem | binary |

  | character_set_results | latin1 |

  | character_set_server | latin1 |

  | character_set_system | utf8 |

  | character_sets_dir | /usr/share/mysql/charsets/ |

  1. 找到mysql的配置文件,拷贝到etc目录下,第一步很重要

  使用find命令查找cnf文件。记得不要去找my.cnf因为它不一定存在,而应该找*.cnf。

  [root@linuxserver classes] find / -iname *.cnf -print

  /usr/share/doc/mysql-server-4.1.12/my-medium.cnf

  /usr/share/doc/mysql-server-4.1.12/my-huge.cnf

  /usr/share/doc/mysql-server-4.1.12/my-innodb-heavy-4G.cnf

  /usr/share/doc/mysql-server-4.1.12/my-large.cnf

  /usr/share/doc/mysql-server-4.1.12/my-small.cnf

  /usr/share/texmf/web2c/mktex.cnf

  /usr/share/texmf/web2c/texmf.cnf

  /usr/share/texmf/web2c/fmtutil.cnf

  /usr/share/texmf/tex/jadetex/jadefmtutil.cnf

  /usr/share/ssl/openssl.cnf

  找到之后,复制一个出来

  cp /usr/share/doc/mysql-server-4.1.12/my-large.cnf /etc/my.cnf

  2. 打开my.cnf修改编码

  vi /etc/my.cnf

  在[client]下增加default-character-set=utf8

  在[mysqld]下增加default-character-set=utf8

  同时加上init_connect=‘SET NAMES utf8’ (设定连接mysql数据库时使用utf8编码,以让mysql数据库为utf8运行)

  重新启动mysql,执行:sudo /etc/init.d/mysql stop 然后sudo /etc/init.d/mysql start

  mysql》 show variables like ‘%character%’;

  +--------------------------+----------------------------+

  | Variable_name | Value |

  +--------------------------+----------------------------+

  | character_set_client | utf8 |

  | character_set_connection | utf8 |

  | character_set_database | utf8 |

  | character_set_filesystem | binary |

  | character_set_results | utf8 |

  | character_set_server | utf8 |

  | character_set_system | utf8 |

  | character_sets_dir | /usr/share/mysql/charsets/ |

  +--------------------------+----------------------------+

  即使做了以上修改如果直接数据库再创建表,然后存入中文,取出来的会是问号。解决的办法是:

  创建数据库的时候指明默认字符集为utf8,如:

  create database test default character set utf8;
