手机连接Mac共享的WiFi的hosts配置问题
安装Homebrew
- Get Xcode;
- Get Command Line Tools.
xcode-select --install; - Install Homebrew.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"; - 其他辅助命令:
check install issue :
brew doctor;To search for an application:
brew search;To install :
brew install <application-name>;To list all apps installed by Homebrew:
brew list;To remove an installed application:
brew remove <application-name>;To update Homebrew:
brew update;To see what else you can do:
man brew;Where does Homebrew install stuff …. in the Cellar:
/usr/local/Cellar/;
- Updating from previous OSX Version
If you are updating from a previous OSX version you may run into file permission issues with El Capitan’s new SIP process .
To get around this you can change ownership on the Homebrew directory sudo chown -R $(whoami):admin /usr/local.
安装dnsmasq
brew install dnsmasq
安装完成后，在/usr/local/文件下新建一个etc文件夹。
把/usr/local/opt/dnsmasq/dnsmasq.conf.example文件拷贝至并重命名为/usr/local/etc/dnsmasq.conf。
编辑dnsmasq.conf，内容如下：
resolv-file=/etc/resolv.conf
strict-order
addn-hosts=/etc/hosts
cache-size=32768
listen-address=127.0.0.1,192.168.xx.154
其中，listen-address后面的可以是多个IP用英文逗号隔开。这里以我自己的IP地址为例，192.168.xx.154是我的Mac mini的内网IP，这样就可以实现同一个局域网内的设备，通过设置DNS为这个IP，来实现都通过我的Mac mini上的dnsmasq来查询dns，即局域网范围内的DNS泛解析。
重启dnsmasq应用
sudo launchctl stop homebrew.mxcl.dnsmasq
sudo launchctl start homebrew.mxcl.dnsmasq
sudo killall -HUP mDNSResponder
可通过以下代码设置开机自动运行dnsmasq：
sudo cp -fv /usr/local/opt/dnsmasq/*.plist /Library/LaunchDaemons
sudo launchctl load /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
最后，使用iPhone连接Mac mini共享的wifi，同时设置dns为我的Mac mini的内网IP地址，即192.168.xx.154。这样再ping以下，就能看到效果
