[系统运维]在MacOS上安装dnsmasq来配置域名模糊匹配

在MacOS上安装dnsmasq来配置域名模糊匹配

前言

如果是简单的域名匹配，在/etc/hosts中直接配置就可以了。

但是如果要配置域名模糊匹配，比如将*.test 都配置指向127.0.0.1，就需要用到dnsmasq。

配置将*.test 都配置指向127.0.0.1

# Install dnsmasq
brew install dnsmasq

# Setup dns configuration
echo 'address=/.test/127.0.0.1' >> /usr/local/etc/dnsmasq.conf
# Restart dnsmasq 
sudo brew services restart dnsmasq

# Add to resolvers
sudo mkdir -p /etc/resolver
sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/test'

# verify
ping abc.test
dig abc.test @127.0.0.1

配置将*.example.com都指向182.61.200.7

# Install dnsmasq
brew install dnsmasq

# Setup dns configuration
# Replace as your domain and IP
echo 'address=/.example.com/182.61.200.7' >> /usr/local/etc/dnsmasq.conf
# Restart dnsmasq 
sudo brew services restart dnsmasq

# Add to resolvers
sudo mkdir -p /etc/resolver
# replace as your domain
sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/example.com'

# verify
ping abc.example.com
dig abc.example.com @127.0.0.1

注意，有些网站会防止跨域访问，所以即使设置了域名映射，也可能会导致访问被拒绝。
