Warning: World-writable config file '/usr/local/mysql51/my.cnf' is ignored

mysql启动时报报如下错
/mysql51/share/mysql/mysql.server start --user=root
Warning: World-writable config file '/usr/local/mysql51/my.cnf' is ignored
Warning: World-writable config file '/usr/local/mysql51/my.cnf' is ignored
Starting MySQL. [ OK ]

原因是my.cnf权限设置的太大，mysql忽略了my.cnf配置文件，采取的默认参数启动的
chmod 644 my.cnf
这种情况下如果启动过mysql
mysql的err日志存在如下错误日志
/usr/local/mysql51/libexec/mysqld: File './mysql-bin.000002' not found (Errcode: 13)
