linux mysql中文乱码解决

测试的机器是ubuntu 12.04个别linux发行版可能略有不同。

登陆mysql查看当前字符集命令：

mysql> show variable like '%char%';

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

配置/etc/mysql/my.cnf文件：

找到[client]在[client]下面增加 default-character-set=utf8

[client]
port            = 3306
socket          = /var/run/mysqld/mysqld.sock
default-character-set   = utf8

找到[mysqld] 下面增加：

character-set-server =utf8

init_connect='SET NAMES utf8'

[mysqld]
#
# * Basic Settings
#
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
character-set-server=utf8
init_connect='SET NAMES utf8'

最后在[mysql]下增加 default-character-set=utf8

[mysql]
default-character-set=utf8

重启mysql就可以了

 sudo /etc/init.d/mysql restart
