MySQL服務(wù)端編碼設(shè)置
安裝完mysql，啟動(dòng)后發(fā)現(xiàn)服務(wù)器默認(rèn)使用的是lat1編碼。
具體操作和查看過程如下：
啟動(dòng)方式：/etc/init.d/mysql.server start
效果：
Database changed
mysql> status
--------------
mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (x86_64) using readline 5.1
Connection id: 8
Current database: demodb
Current user: root@localhost
SSL: Not in use
Current pager: stdout
Using outfile: ''
Using delimiter: ;
Server version: 5.5.21 MySQL Community Server (GPL)
Protocol version: 10
Connection: Localhost via UNIX socket
Server characterset: latin1
Db characterset: utf8
Client characterset: latin1
Conn. characterset: latin1
UNIX socket: /var/lib/mysql/mysql.sock

啟動(dòng)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

這種方式,在每次啟動(dòng)的時(shí)候都需要指定編碼參數(shù)。否則服務(wù)器就使用的是系統(tǒng)默認(rèn)的lat1編碼。
另外一種方法是：
這種方法我也試了，不行，再重新登錄客戶端后，就又恢復(fù)了原來的編碼。理由很簡單，系統(tǒng)啟動(dòng)的時(shí)候用的不是utf8編碼。
一勞永逸的辦法,就是通過修改配置文件實(shí)現(xiàn).
# vim /etc/my.cnf
內(nèi)容如下:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
#添加下面的紅字內(nèi)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
