为什么Ansible无法挂载Vagrant远程NFS共享 [英] Why won't Ansible mount Vagrant remote NFS share

问题描述

当我尝试执行安装模块时，我的Ansible剧本出现了一个错误:

My Ansible playbook is raising an error when I try to execute the mount module:

Error mounting 192.168.33.1:/Users/me/playbooks/site1/website: mount.nfs: remote share not in 'host:dir' format

代码目录已安装:

$ vagrant ssh -c "mount | grep http"
192.168.33.1:/Users/me/playbooks/site1/website on /srv/http/site1.com type nfs (...)

Vagrantfile:

Vagrantfile:

Vagrant.configure("2") do |config|
  config.vm.box = "debian/jessie64"
  config.vm.network "forwarded_port", guest: 80, host: 8080
  config.vm.network "forwarded_port", guest: 443, host: 8443
  config.vm.network "private_network", ip: "192.168.33.10"
  config.vm.synced_folder "website/", "/srv/http/site1.com", nfs: true
end

Ansible剧本:

Ansible playbook:

- name: Remount code directory
  hosts: web
  sudo: True
  tasks:
    - name: unmount website
      mount:
        name: /srv/http/site1.com
        src: srv_http_site1.com
        fstype: nfs
        state: unmounted
    - name: remount website
      mount: 
        name="192.168.33.1:/Users/me/playbooks/site1/website"
        src="srv_http_site1.com" 
        fstype=nfs 
        state=mounted

我正在运行NFS v3:

I'm running NFS v3:

$ sudo nfsstat | grep nfs  # => Client nfs v3

我不确定为什么会这样.卸载任务将卸载文件系统，但以下装载任务失败. mount(8)手册页显示设备可能看起来像knuth.cwi.nl:/dir". nfs(5)手册页指出，服务器主机名可以是点分四组IPv4地址".我尝试将以下行添加到我的/etc/hosts文件中:

I'm not sure why this is happening. The unmount task will unmount the filesystem but the following mount tasks fails. The mount(8) man page says "device may look like knuth.cwi.nl:/dir". The nfs(5) man page says that server host names can be "a dotted quad IPv4 address". I tried adding the following line to my /etc/hosts file:

laptop    192.168.33.1

，然后将挂载名称参数"192.168.33.1"替换为"laptop"，但这也没有解决.有人看到我在做什么错吗?

and then replacing the mount name argument "192.168.33.1" with "laptop" but that didn't fix it either. Does anyone see what I'm doing wrong?

谢谢.

推荐答案

您的Ansible剧本似乎有几个问题.最后一部分不是有效的YAML，但更重要的是，您的安装中的name和src被颠倒了.文档指出" src是要挂载到名称上的设备".名称也应该是安装点的路径.这是解决了这些问题的剧本...

You seem to have a couple of issues with your Ansible playbook. The last part is not valid YAML, but more importantly the name and src in your mounts are reversed. The docs state that "src is device to be mounted on name". Also the name should be the path to the mount point. Here's the playbook with those issues resolved...

- name: Remount code directory
  hosts: web
  sudo: True
  tasks:
    - name: unmount website
      mount:
        name: /srv/http/site1.com
        src: 192.168.33.1:/Users/me/playbooks/site1/website
        fstype: nfs
        state: unmounted
    - name: remount website
      mount:
        name: /srv/http/site1.com
        src: 192.168.33.1:/Users/me/playbooks/site1/website
        fstype: nfs
        state: mounted

如果您进行了这些更改并注释了Vagrantfile中的synced_folder，我认为它会以您想要的方式工作.

If you make these changes and comment out the synced_folder in your Vagrantfile, I think it will work in the way that you want.
