Linux下MySQL5.6的修改字符集编码为UTF8(解决中文乱码问题)
Linux下MySQL5.6的修改字符集编码为UTF8(解决中文乱码问题)
一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%’;下字符集,显示如下:
1 2 3 4 5 6 7 8 9 10 11 12 | + --------------------------+----------------------------+ | Variable_name | Value | + --------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | latin1 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | + --------------------------+----------------------------+ |
character_set_database和character_set_server的默认字符集还是latin1。
二、最简单的完美修改方法,修改mysql的my.cnf文件中的字符集键值(注意配置的字段细节):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | 1、在[client]字段里加入 default - character - set =utf8,如下: [client] port = 3306 socket = /var/lib/mysql/mysql.sock default - character - set =utf8 2、在[mysqld]字段里加入 character - set -server=utf8,如下: [mysqld] port = 3306 socket = /var/lib/mysql/mysql.sock character - set -server=utf8 3、在[mysql]字段里加入 default - character - set =utf8,如下: [mysql] no -auto-rehash 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。这点在网上没人反馈过。
使用SHOW VARIABLES LIKE ‘character%’;查看,发现数据库编码全已改成utf8。
