解决Unbound报错unknown keyword ‘tls-*’

GENERAL

在配置Unbound时遇到如下错误：

/etc/unbound/unbound.conf:16: error: unknown keyword 'tls-service-key' 
/etc/unbound/unbound.conf:16: error: stray ':' 
/etc/unbound/unbound.conf:16: error: stray '"' 
/etc/unbound/unbound.conf:16: error: unknown keyword 'key.pem' 
/etc/unbound/unbound.conf:16: error: stray '"' 
/etc/unbound/unbound.conf:17: error: unknown keyword 'tls-service-pem' 
/etc/unbound/unbound.conf:17: error: stray ':' 
/etc/unbound/unbound.conf:17: error: stray '"' 
/etc/unbound/unbound.conf:17: error: unknown keyword 'fullchain.pem' 
/etc/unbound/unbound.conf:17: error: stray '"' 
/etc/unbound/unbound.conf:18: error: unknown keyword 'tls-port' 
/etc/unbound/unbound.conf:18: error: stray ':' 
/etc/unbound/unbound.conf:18: error: unknown keyword '853' 
read /etc/unbound/unbound.conf failed: 13 errors in configuration file [1579421749] unbound[17698:0] fatal error: Could not read config file: /etc/unbound/unbound.conf

搜寻后得知是官方文档有变更，将tls全部改为ssl即可。

树莓派WiFi设置静态IP

GENERAL、

ifconfig查看网络接口：

此处选择wlan0

编辑/etc/network/interfaces

修改或添加以下内容：

auto wlan0
 iface wlan0 inet manual
 wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

注意不能写成iface wlan0 inet dhcp，否则dhcpcd不会生效。

编辑/etc/dhcpcd.conf

在文件末尾添加以下内容：

interface wlan0
 static ip_address=192.168.1.100/24
 static routers=192.168.1.1
 static domain_name_servers=192.168.1.1

修改wlan0为你的网络接口，ip_address为你的IP地址，routers为你的网关，domain_name_servers为你的dns。

完成后重启系统即可。
