启动mysql 报错 Couldn't find MySQL server (/usr/bin/mysqld_safe),需要在my.cnf中配置路径 basedir=/home/web/mysql
再重新启动，报错 The server quit without updating PID file (/var/run/mysqld/mysqld.pid)
查看log日志 Can't find messagefile '/usr/share/mysql/errmsg.sys
将源码包里面的sql/share/english/errmsg.sys复制到/usr/share/mysql/errmsg.sys
