mysql启动报 [ERROR] Can't read from messagefile '/usr/local/mysql/share/errmsg.sys'
网上有一些解决方案，让mysql找到正确路径。

这里提供一个逆向解决方案。
在mysql代码里可以找到errmsg.sys
[root@mysql1 5627]# find . -name errmsg.sys
./sql/share/danish/errmsg.sys
./sql/share/bulgarian/errmsg.sys
./sql/share/english/errmsg.sys
./sql/share/dutch/errmsg.sys
./sql/share/slovak/errmsg.sys
./sql/share/ukrainian/errmsg.sys
./sql/share/greek/errmsg.sys
./sql/share/portuguese/errmsg.sys
./sql/share/estonian/errmsg.sys
./sql/share/czech/errmsg.sys
./sql/share/korean/errmsg.sys
./sql/share/serbian/errmsg.sys
./sql/share/japanese/errmsg.sys
./sql/share/hungarian/errmsg.sys
./sql/share/french/errmsg.sys
./sql/share/swedish/errmsg.sys
./sql/share/polish/errmsg.sys
./sql/share/romanian/errmsg.sys
./sql/share/russian/errmsg.sys
./sql/share/german/errmsg.sys
./sql/share/spanish/errmsg.sys
./sql/share/norwegian-ny/errmsg.sys
./sql/share/norwegian/errmsg.sys
./sql/share/italian/errmsg.sys

把英文的放到它要求的路径完事。
[root@mysql1 5627]# cp ./sql/share/english/errmsg.sys /usr/local/mysql/share/errmsg.sys
cp: overwrite `/usr/local/mysql/share/errmsg.sys'? y

开始我以为是要写点错误日志，给它touch一个就行，结果还是报错。
原来errmsg是多语言支持用的。
