http://www.vcerror.com/?p=2044问题描述:给passwd文件加权限,修改/etc/passwd目录下所有的文件夹属性为可写可读可执行,执行以下命令:chomd 777 /etc/passwd的时候提示错误:chmod: changing permissions of ‘/etc/passwd': Read-only file system解决方法:产生这个问题的原因是文件系统此时处于只读模式下,/etc/passwd和/etc/shadow不能被修改,运行下面的命令就可以解决这个问题#mount -rw -o remount /注: mount 是挂载命令 -rw 是说指定的挂载文件是可读/写的 -o remount / 是说重新挂载根
