mysql Can't find messagefile errmsg.sys解决方法

=故障来了=
<pre>
mysql 启动不了 ，报错如下 
[root@ ~]# /etc/init.d/mysqld  start
Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/data/vultr.guest.pid). </pre>

=分析处理过程=
<pre>
为了查看深入而不表面的原因 当然是得查看 err log嘛 
[root@ ~]# cat  /data/mysqld-error.log

网上查看了很多方法  很多 小伙伴还说是内存问题 哈哈  那为什么以前才512M ram都可以 跑呢 而现在 1G ram不能跑 哈哈 
 
实在没办法  我打算重新编译安装一个新的mysql ，但不和老的同目录的，但是后来试一下 将源码包里面的sql/share/  复制到 mysql/share 就好  ，回想起来 可能是我上次不小心删除了 share目录
