Autofs 和 Samba 无法在 RHEL 7 上安装

Autofs 和 Samba 无法在 RHEL 7 上安装

我设置了一个名为“scrolls”的 Samba 共享。列出 Samba 共享即可正常工作：

[root@rhel7-client ~]# smbclient -L 192.168.1.2
Enter root's password:


Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.1]

Sharename       Type      Comment
---------       ----      -------
scrolls         Disk      Ancient Scrolls
IPC$            IPC       IPC Service (Samba 4.1.1)
root            Disk      Home Directories
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.1]

Server               Comment
---------            -------

Workgroup            Master

安装 samba 共享也可以：

[root@rhel7-client /]# mount.cifs //192.168.1.2/scrolls -o credentials=/etc/creds.txt /mnt

[root@rhel7-client /]# grep scrolls /etc/mtab|tail -n1
//192.168.1.2/scrolls /mnt cifs   rw,relatime,vers=1.0,cache=strict,username=root,domain=RHEL7SERVER,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.1.2,unix,posixpaths,serverino,acl,rsize=1048576,wsize=65536,actimeo=1 0 0

卸载前一个共享后，通过 Autofs 安装 Samba 共享不起作用：

[root@rhel7-client /]# cat /etc/auto.shares
scrolls         -cifs,credentials=/etc/creds.txt                //192.168.1.2/scrolls

[root@rhel7-client scrolls]# grep shares /etc/auto.master
/mnt/shares /etc/auto.shares

[root@rhel7-client /]# grep shares /etc/mtab
/etc/auto.shares /mnt/scrolls autofs rw,relatime,fd=-1,pgrp=2548,timeout=300,minproto=5,maxproto=5,indirect 0 0
/etc/auto.shares /mnt/shares autofs rw,relatime,fd=12,pgrp=2730,timeout=300,minproto=5,maxproto=5,indirect 0 0

[root@rhel7-client /]# cd /mnt/shares/scrolls
-bash: cd: /mnt/shares/scrolls: No such file or directory

有任何想法吗？

[root@rhel7-client scrolls]# systemctl status autofs

答案1

这应该是由于您的自动挂载配置造成的：

在使用时，您必须添加SMB 共享所需://192.168.1.2/scrolls的:autofs

[root@rhel7-client /]# cat /etc/auto.shares

scrolls         -cifs,credentials=/etc/creds.txt              ://192.168.1.2/scrolls

答案2

在 /etc/auto.master 中使用选项 --ghost。我没有在文档中找到它，但它在我的环境中有效。

/mnt/shares /etc/auto.shares --ghost
