  • linux下设置mysql数据库字符集utf8

    mysql中文乱码解决方法:将mysql数据库编码统一utf8

    查看数据库编码:

    show variables like 'character%';

    编辑/etc/my.cnf

    [mysql]
    default-character-set=utf8
    [mysqld]
    datadir=/var/lib/mysql
    socket=/var/lib/mysql/mysql.sock
    user=mysql
    # Disabling symbolic-links is recommended to prevent assorted security risks
    symbolic-links=0
    default-character-set = utf8
    character_set_server = utf8
    #lower_case_table_names=1  忽略大小写
    [mysqld_safe]
    log-error=/var/log/mysqld.log
    pid-file=/var/run/mysqld/mysqld.pid
    default-character-set = utf8
    [mysql.server]
    default-character-set = utf8
    [client]
    default-character-set = utf8
    

      

    修改完成后,service mysql restart重启mysql服务就生效。注意:[mysqld]字段与[mysql]字段是有区别的。  

    如果上面的都修改了还乱码,那剩下问题就一定在connection连接层上。解决方法是在发送查询前执行一下下面这句(直接写在SQL文件的最前面):
    SET NAMES 'utf8';

    它相当于下面的三句指令:

    SET character_set_client = utf8;
    SET character_set_results = utf8;
    SET character_set_connection = utf8;

    执行show variables like 'character%' 跟下面一样说明修改成功

    mysql> show variables like 'character%';

    | 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/ |
    +--------------------------+----------------------------+
