mac 10.9 无法解析hosts的问题解决

由于系统的dns服务器优先于hosts，导致无法解析部分hosts了，唯一的解决方式是安装dnsmasq域名解析服务

以下是亲自操作的步骤：

brew install -vd --use-gcc dnsmasq

cp /usr/local/Cellar/dnsmasq/2.68/dnsmasq.conf.example /usr/local/etc/dnsmasq.conf // 复制配置文件到指定目录

cp /usr/local/Cellar/dnsmasq/2.68/homebrew.mxcl.dnsmasq.plist /Library/LaunchDaemons // 配置dns的自启动

launchctl load -w /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist // 开机自启动

vim /etc/resolv.dnsmasq.conf: // 默认的resolv.conf会被系统覆盖，所以创建一个新文件写入旧的dns

     nameserver 192.168.1.114
     nameserver 202.106.0.20

vim /usr/local/etc/dnsmasq.conf: resolv-file=/etc/resolv.dnsmasq.conf // 执行dns配置文件

launchctl start homebrew.mxcl.dnsmasq // 进程名称为plist中的label，手动启动，马上看到效果

然后用wget测试一下：
