执行客户端挂载目录提示mount.nfs: access denied by server while mounting

这个错误提示表明您的 NFS 服务器拒绝了客户端的挂载请求，通常是由于权限配置或防火墙等原因引起的。

您可以检查以下几个方面：

1. 检查 NFS 服务器的配置文件，确保客户端所在的 IP 地址被允许访问，并且目录的权限设置正确。

2. 检查客户端的防火墙设置，确保 NFS 端口（TCP/UDP 2049）被允许通过。

3. 尝试使用不同的挂载选项，例如设置 no_root_squash 选项可以解决某些权限问题。

4. 检查客户端和服务器之间的网络连接是否正常，例如通过 ping 命令测试网络连通性。

如果以上方法都无法解决问题，建议您查看服务器和客户端的日志文件，以获取更详细的错误信息。

mount.nfs: access denied by server while mounting

This error message indicates that the NFS server is not allowing the client to access the desired NFS share. There are several possible reasons for this error, including:

1. Incorrect permissions: The NFS share may not have the correct permissions set up to allow the client to access it. Check the permissions on the NFS server to ensure that the client has read and/or write access to the share.

2. Firewall issues: The firewall on the NFS server may be blocking access from the client. Check the firewall rules on the NFS server to ensure that the client is allowed to access the NFS share.

3. DNS issues: The client may be unable to resolve the hostname of the NFS server. Check the DNS settings on the client to ensure that it can resolve the hostname of the NFS server.

4. NFS service not running: The NFS service on the server may not be running. Check that the NFS service is running on the server.

5. Incorrect syntax: The syntax of the mount command may be incorrect. Double-check the syntax of the mount command to ensure that it is correct.

To resolve this error, you will need to troubleshoot the issue by checking the permissions, firewall rules, DNS settings, NFS service, and mount command syntax.

安装部署NFS server，现在客户端挂载报错：mount -t nfs -o nfsvers=3 192.168.1.121:/test/test1/ /mnt -vvvv mount.nfs: timeout set for Wed Jun 7 19:14:52 2023 mount.nfs: trying text-based options 'nfsvers=3,addr=192.168.1.121' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 192.168.1.121 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 192.168.1.121 prog 100005 vers 3 prot UDP port 20048 mount.nfs: mount（2）: Permission denied mount.nfs: access denied by server while mounting 192.168.1.121:/test/test1/

这个错误提示表明NFS客户端无法访问NFS服务器上的共享目录，可能是由于权限问题导致的。您可以尝试以下步骤解决这个问题：

1. 检查NFS服务器上的共享目录是否已正确配置为允许指定的客户端进行访问，并且客户端的IP地址是否正确。

2. 确保NFS服务器上的共享目录已经挂载并且可以访问，可以在服务器上使用“showmount -e”命令查看共享目录的状态。

3. 检查NFS服务器上的共享目录的权限设置是否正确，可以使用“chmod”和“chown”命令更改权限设置。

4. 确保防火墙已正确配置以允许NFS流量通过，可以暂时关闭防火墙以进行测试。
