我希望将以下安装永久化:
[michael@devserver ~]$ findmnt | grep public
└─/home/jail/home/public/repo /dev/mapper/centos-root[/home/michael/testing/gateway/repo] xfs ro,relatime,attr2,inode64,noquota
[michael@devserver ~]$
我使用以下命令创建了这个安装:
sudo mkdir /home/jail/home/public/repo
sudo mount --bind /home/michael/testing/gateway/repo /home/jail/home/public/repo
sudo mount -o remount,ro,bind /home/jail/home/public/repo
我/etc/fstab
目前的样子如下。我原以为我应该添加/home/michael/testing/gateway/repo /home/jail/home/public/repo xfs ro,relatime,attr2,inode64,noquota 0 0
到/etc/fstab
,但是这样做后,我的服务器就会阻塞,我必须进入紧急模式才能从 中删除这一行/etc/fstab
。永久绑定挂载目录以进行只读访问的正确方法是什么?
[michael@devserver ~]$ cat /etc/fstab

答案1
好吧,您的/etc/fstab
文件似乎没有bind
配置挂载点。请善意地添加以下行:
/home/michael/testing/gateway/repo /home/jail/home/public/repo none bind,ro 0 0.
然后,我将键入以下命令来验证 mountpoint 是否持久且有效。
mount /home/jail/home/public/repo
之后,您可以重新启动系统。
