NFS权限在Gitlab的ubuntu / EC2上被拒绝

我有两个AWS EC2 Ubuntu实例。 我在这两台主机上configuration了NFS来共享Gitlab之间的目录。 我打开了AWS防火墙，因此可以接受，并且使用Nmap打开了端口

• 服务器1具有IP XX.XX.XX.XX
• 服务器2具有IP YY.YY.YY.YY

在我的fstab我configuration在服务器1上：

XX.XX.XX.XX:/var/opt/gitlab/.ssh /var/opt/gitlab/.ssh nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 XX.XX.XX.XX:/var/opt/gitlab/gitlab-rails/uploads /var/opt/gitlab/gitlab-rails/uploads nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 XX.XX.XX.XX:/var/opt/gitlab/gitlab-rails/shared /var/opt/gitlab/gitlab-rails/shared nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 XX.XX.XX.XX:/var/opt/gitlab/gitlab-ci/builds /var/opt/gitlab/gitlab-ci/builds nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 XX.XX.XX.XX:/var/opt/gitlab/git-data /var/opt/gitlab/git-data nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 

Iny我的服务器2的fstab：

 YY.YY.YY.YY:/var/opt/gitlab/.ssh /var/opt/gitlab/.ssh nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 YY.YY.YY.YY:/var/opt/gitlab/gitlab-rails/uploads /var/opt/gitlab/gitlab-rails/uploads nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 YY.YY.YY.YY:/var/opt/gitlab/gitlab-rails/shared /var/opt/gitlab/gitlab-rails/shared nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 YY.YY.YY.YY:/var/opt/gitlab/gitlab-ci/builds /var/opt/gitlab/gitlab-ci/builds nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 YY.YY.YY.YY:/var/opt/gitlab/git-data /var/opt/gitlab/git-data nfs defaults,soft,rsize=1048576,wsize=1048576,noatime,lookupcache=positive 0 2 

如果我在其中一台主机上运行$ mount -a，我得到以下错误：

• 那里有一个我可以使用的AWS服务来反向托pipe在vpc中的代理微服务，并且不能被公开？
• 如何从AWS MySQL导出（程序encryption的数据）到Google MySQL？
• AWS：通过脚本访问精确定位的IAM用户凭据会导致InternalServerError
• 切换静态IP寻址后，我无法从我的ec2实例访问互联网
• 如何重写Amazon Application Load Balancer中的path？

 [email protected]:/var/opt/gitlab/git-data# mount -a mount.nfs: access denied by server while mounting XX.XX.XX.XX:/var/opt/gitlab/.ssh mount.nfs: access denied by server while mounting XX.XX.XX.XX:/var/opt/gitlab/gitlab-rails/uploads mount.nfs: access denied by server while mounting XX.XX.XX.XX:/var/opt/gitlab/gitlab-rails/shared mount.nfs: access denied by server while mounting XX.XX.XX.XX:/var/opt/gitlab/gitlab-ci/builds mount.nfs: access denied by server while mounting XX.XX.XX.XX:/var/opt/gitlab/git-data 

正如我写的防火墙是开放的，端口是开放的。

你有什么问题吗？ 我从nfs阅读手册，其实我认为我configuration一切正确？ 我使用私有AWS IP，这不应该有任何区别

PS：在/ etc / fstab中，我还添加了nobootwait选项，但不包含在ubuntu中。
