我无法在启动时启动 dnsmasq

  • 772

这些是我输入时得到的输出：

 systemctl status dnsmasq

 ● dnsmasq.service - dnsmasq - A lightweight DHCP and caching DNS server
Loaded: loaded (/lib/systemd/system/dnsmasq.service; enabled; vendor preset: enabled)

Dec 14 08:49:31 raspberrypi systemd[1]: dnsmasq.service: Failed with result 'exit-code'.

当我手动启动服务时它工作正常。

我已经设置了这样的静态IP：

sudo nano /etc/dhcpcd.conf


interface wlan0
static ip_address=10.0.20.1/24
static routers=10.0.20.0
dnsmasq

  1. Dec 14 08:49:31 raspberrypi dnsmasq[590]: dnsmasq: failed to create listening socket for 10.0.20.1: Cannot assign requested address

    10.0.20.1此行表示当 dnsmasq 启动时，您的机器没有系统上的地址。添加此地址后，您需要重新配置 systemd 单元以启动。这可以通过使用 systemd 插件来完成。创建目录/etc/systemd/system/dnsmasq.service.d并将以下内容添加到该目录中具有.conf扩展名的文件中：

    [Unit]
After=network-online.target

    这假设您的网络以通常的方式联机，并且它属于该network-online.target单元。如果没有，那么这将不起作用，您需要相应地进行调整。

    我解决了这个问题

    我删除了这样的 ip

    sudo nano /etc/dhcpcd.conf


interface wlan0
static ip_address=10.0.20.1/24
static routers=10.0.20.0

    我把 ip 给了这样的接口。

     sudo nano /etc/network/interfaces


 # interfaces(5) file used by ifup(8) and ifdown(8)

 # Please note that this file is written to be used with dhcpcd
 # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

 # Include files from /etc/network/interfaces.d:
 source-directory /etc/network/interfaces.d

 auto wlan0
 iface wlan0 inet static
 address 10.0.20.1
 netmask 255.255.255.0

 auto eth0
 iface eth0 inet dhcp
