面我们来看看关于启动mysql出错：Can't find messagefile '/usr/share/mysql/errmsg.sys出错问题的解决办法吧．
启动数据库出现错误，错误信息是：
[ERROR] Can't find messagefile '/usr/share/mysql/errmsg.sys'
root@debian:/usr/local# /etc/init.d/mysql3306 start

...The server quit without updating PID file (/home/www/mysql/m3306/mysql3306.pid). ... failed!

120102 14:12:00 mysqld_safe mysqld from pid file /home/www/mysql/m3306/mysql3306.pid ended
解决方法是：
root@debian:/usr/local# vi mysql3306/my.cnf
加入language配置项，由于我是使用二进制分发包进行安装的，而默认的情况下，mysql会到/usr/local/mysql/share/english下查找该文件，
但由于我的mysql安装路径 为/usr/local/mysql3306/，所以如下：
[mysqld]
pid-file = /home/www/mysql/m3306/mysql3306.pid
log-error = /home/www/mysql/m3306/mysql3306.err
language = /usr/local/mysql3306/share/english #此处为language配置项
port = 3306
socket = /tmp/mysql3306.sock
basedir = /usr/local/mysql3306
datadir = /home/www/mysql/m3306
重新启动：
root@debian:/usr/local# /etc/init.d/mysql3306 start
Starting MySQL
...
已成功启动。
