dnsmasq 重启失败

  • 772

每当我想重新启动dnsmasq服务时，我都会收到此错误

root@ipm:/tftpboot# /etc/init.d/dnsmasq restart
[....] Restarting dnsmasq (via systemctl): dnsmasq.serviceJob for
dnsmasq.service failed because the control process exited with error code.
See "systemctl status dnsmasq.service" and "journalctl -xe" for details.
 failed!

如错误消息中所述，这些命令中没有有用的信息。

# systemctl status dnsmasq.service

Hint: Some lines were ellipsized, use -l to show in full.

的内容dnsmasq.conf是

 # cat /etc/dnsmasq.conf
 interface=enp3s0
 domain=hpclab
 expand-hosts
 dhcp-range=192.168.1.1,192.168.1.20,static
 dhcp-option=42,0.0.0.0
 dhcp-boot=pxelinux.0
 enable-tftp
 tftp-root=/tftpboot
 dhcp-host=00:e0:81:c5:19:64,ws01,192.168.1.1

所以，第 4 行是dhcp-range=192.168.1.1,192.168.1.20,static. 我在 ubuntu-12.04 中使用了相同的内容。

更新：

无论如何，正确的语法是dhcp-range=192.168.1.0,static. 我不知道 12.04 是如何工作的！

    4 11:04:42 dnsmasq [18806]：dnsmasq：第 4 行 o...f 的 dhcp 范围错误

    这对我来说看起来很有用——你读过吗？好像你的配置有问题。

    提示：有些线条是椭圆的，使用 -l 来完整显示。

    这也是有用的信息——当你使用它时会发生什么？

    systemctl status -l dnsmasq.service

    说真的，请阅读您提供的信息，我们不是错误消息阅读服务。
