shell脚本自动配置新装服务器相关配置

每次新装服务器后，总要配置一大堆东西，重复过来，重复过去，我这个人就是不喜欢把时间浪费在相同的事情上面，所以果断写了一个脚本，自动修改主机名，网关，双网卡绑定（包括重置IP地址功能），重启网络，自动配置ntp时间同步服务，自动配置dns服务。由于修改主机名需要重启生效，所以在最后加了重启选项。当所有配置完毕，可以按7完成重启。
将脚本拷贝到服务器任意路径，赋权chmod +x autocfg.sh，然后./autocfg.sh 执行脚本即可。这个脚本我已经在虚拟机上测试过了，可以达到正确效果，希望可以为以后生产环境的配置带来方便，当然可能会有潜在的bug，由于时间问题，没有考虑太多的捕获异常。只要根据提示操作，是可以正确执行的。
不罗嗦，直奔主题，献上脚本：
由于篇幅问题，只选取部分例子的执行效果：

这是第二个版本，以后还会根据需要陆续往里加内容。希望这个脚本能给更多奋斗在运维岗位的朋友带来帮助。
