1.首先，通过以下命令进入mysql
[root@VM_168_4_centos ~]# cd /[root@VM_168_4_centos /]# cd usr/etc[root@VM_168_4_centos etc]# mysql
2.然后查看mysql的字符集编码
mysql>show variables like "character_set%";+--------------------------+----------------------------+ | 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/ | +--------------------------+----------------------------+
3.然后进入etc下的f文件
cd etcvim f
找到如下代码
[mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
4.修改文件，在 [mysqld_safe] 的上面粘贴如下三行,然后保存
character-set-server=utf8 [mysql] default-character-set=utf8
5.重启mysql服务：service mysqld restart
再次查看编码 ：show variables like "character_set%";
+--------------------------+----------------------------+| 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/ |+--------------------------+----------------------------+
