昨天 Veeam 纳管一台 Ubuntu 20.04 时遇到了一些问题，先是提示主机需要联外网下载依赖，配置网络之后，agent 安装又失败了，报错：

Bash

12025/11/18 17:06:50 Warning Failed to connect to 10.199.41.71 Details: Failed to execute agent management command print. No such file or directory Failed to connect: /var/tmp/veeam/socket/veeamservice.sock. Failed to connect to veeamservice daemon.

本文记录一下分析过程以及解决步骤。

问题分析

首先查看主机系统版本：

Bash

1root@apods01:~# cat /etc/lsb-release 
2DISTRIB_ID=Ubuntu
3DISTRIB_RELEASE=20.04
4DISTRIB_CODENAME=focal
5DISTRIB_DESCRIPTION="Ubuntu 20.04.1 LTS"

VBR 纳管报错，格式化内容之后如下：

Bash

1Failed to install 
2veeam_6.3.1.1016_amd64.deb, 
3veeam-libs_6.3.1.1016_amd64.deb

15Could not connect to archive.ubuntu.com:80 (91.189.91.83),

17connection timed out Could not connect to archive.ubuntu.com:80 (91.189.91.82), 
18connection timed out

联系网络管理员临时开通外网后，重新执行 Rescan，提示安装成功，但是执行备份的时候报错：

Bash

12025/11/18 17:06:50 Warning Failed to connect to 10.199.41.71 Details: Failed to execute agent management command print. No such file or directory Failed to connect: /var/tmp/veeam/socket/veeamservice.sock. Failed to connect to veeamservice daemon.

查看 Rescan 日志：

Bash

1[18.11.2025 17:01:24.248]    <18>   Error (3)    Agent management command has failed, exit code 255, error text: No such file or directory
2[18.11.2025 17:01:24.248]    <18>   Error (3)    Failed to connect: /var/tmp/veeam/socket/veeamservice.sock.
3[18.11.2025 17:01:24.248]    <18>   Error (3)    Failed to connect to veeamservice daemon.
4[18.11.2025 17:01:24.248]    <18>   Error (3)    Failed to process discovery operation for Linux host: 10.199.41.71
5[18.11.2025 17:01:24.248]    <18>   Error (3)    Failed to execute agent management command print. No such file or directory
6[18.11.2025 17:01:24.248]    <18>   Error (3)    Failed to connect: /var/tmp/veeam/socket/veeamservice.sock.
7[18.11.2025 17:01:24.248]    <18>   Error (3)    Failed to connect to veeamservice daemon. (System.Exception)

检查主机上是否存在这个文件：

Bash

1root@apods01:~# cd /var/tmp/veeam/socket/
2-bash: cd: /var/tmp/veeam/socket/: No such file or directory

当前主机不存在以上文件，但是正常纳管的主机是存在的：

Bash

1[root@SQCSLEAP01N ~]# cd /var/tmp/veeam/socket
2[root@SQCSLEAP01N socket]# ls
3events.sock  veeamservice.sock

看来就是因为这个了，怀疑是第一次安装的时候有问题，尝试卸载 agent 后重新安装：

https://helpcenter.veeam.com/docs/agentforlinux/userguide/uninstallation_process.html?ver=60

首先卸载安装的 veeam 相关依赖：

Bash

1apt-get remove veeam veeam-libs veeamsnap
2apt-get remove veeam veeam-libs blksnap
3apt-get remove veeam-nosnap veeam-libs

删除 veeam 安装目录：

Bash

1root@apods01:/opt# rm -rf veeam/
2root@apods01:/opt# 
3root@apods01:/opt# ll
4total 8
5drwxr-xr-x  2 root root 4096 Nov 18 09:23 ./
6drwxr-xr-x 21 root root 4096 May 31  2024 ../

杀掉所有 veeam 相关进程：

Bash

1root@apods01:/opt# ps -ef|grep veeam
2root      463548       1  0 09:22 ?        00:00:00 /opt/veeam/transport/veeamtransport --run-service

7root      463655  463653  0 09:22 ?        00:00:00 /opt/veeam/deployment/veeamdeploymentsvc --vcp-subprocess 18:17

9root@apods01:/opt# kill -9 463651

15root      465271  392310  0 09:24 pts/0    00:00:00 grep --color=auto veeam

在 VBR 重新执行 rescan，成功安装 agent，可以正常备份。

写在最后

Veeam 纳管 Ubuntu 系统需要提前开通外网下载 deb 依赖包，否则会纳管失败。
