![OpenVPN 服务无法启动](https://linux22.com/image/672733/OpenVPN%20%E6%9C%8D%E5%8A%A1%E6%97%A0%E6%B3%95%E5%90%AF%E5%8A%A8.png)
我在我的 VPS (Fedora 23) 上配置了 OpenVPN,但在将其作为 systemd 服务启动时遇到了问题。从命令行 ( openvpn server.conf
) 一切正常,但当我尝试通过 systemd 启动它时失败了。
systemctl status [email protected]
给我看看这个:

Dec 10 06:04:07 myvps systemd[1]: [email protected]: Failed with result 'exit-code'.
我看到 OpenVPN 无法执行ip
命令,但我不知道为什么。当我手动启动 OpenVPN 时,我没有收到此错误。
unpriv-ip 脚本的设置如下官方指南。
OpenVPN 服务将在之后启动,如果重要的话,network.target
需要。multi-user.target
有人能解释一下我这个问题是什么吗?
谢谢。

答案1
- 检查
/usr/local/sbin/unpriv-ip
脚本是否执行权限(+x chmod 标志)
你可以用以下命令进行设置
chmod +x /usr/local/sbin/unpriv-ip
检查您的 openvpn 配置是否有
script-security 2
允许执行外部脚本的行。确保您已
iproute
安装软件包并且ip
系统上可用该命令。
您可以使用以下方式安装:
yum install iproute iputils
- 尝试添加
sleep 5
到脚本的顶部,/usr/local/sbin/unpriv-ip
以确保它不会在 tun0 设备可用之前执行。
