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/mysqlsocket=/var/lib/mysql/mysql.sockuser=mysql# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0default-character-set = utf8character_set_server = utf8#lower_case_table_names=1 忽略大小写[mysqld_safe]log-error=/var/log/mysqld.logpid-file=/var/run/mysqld/mysqld.piddefault-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%‘;+--------------------------+----------------------------+| 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/ |+--------------------------+----------------------------+8 rows in set (0.00 sec)
