本篇内容主要讲解“mysql服务端编码的设置”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“mysql服务端编码的设置”吧!

安装完,启动后发现服务器默认使用的是lat1编码.
 
具体操作和查看过程如下:
 
启动方式: /etc/init.d/mysql.server start
 
效果:
 
Database changed
mysql> status

启动方式: /etc/init.d/mysql.server start --character-set-server=utf8
 
效果:
mysql> use demodb;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

这种方式,在每次启动的时候都需要指定编码参数.否则服务器就使用的是系统默认的lat1编码.
 
 
另外一种方法是:
 
mysql>set character_set_server=utf8;
 
这种方法我也试了,不行,再重新登录客户端后,就又恢复了原来的编码.理由很简单,系统启动的时候用的不是utf8编码.
 
 
一劳永逸的办法,就是通过修改配置文件实现.
 
# vim /etc/my.cnf
 
内容如下:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
 
#添加下面的红字内容
character-set-server=utf8
 
 
 
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
 
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
