最近在弄微信的电子发票涉及到了跨域的问题。页面又是用h5写的不好使用框架中的代理操作。加上最近刚好了阿里云服务器，想着买了就不能浪费的原则就开始用阿里云的服务器搭建个ng来玩玩。因为没有搭建过就网上各种百度文档，url https://www.cnblogs.com/kingsonfu/p/9804131.html；配置过程中碰见了一些其他的问题，比如在设置ng端口的时候会碰见防火墙没开导致配置的端口报错。使用 systemctl start firewalld 命令打开防火墙既可以继续配置ng端口。另外就是会碰见ng启动失败的问题；
经查找，发现因为nginx没有有添加到系统服务，所以才报错的，我们可以手动手动添加一个即可。在/etc/init.d/下创建名为nginx的启动脚本即可
#!/bin/sh

esac
创建完脚本之后
设置执行权限：chmod +x /etc/init.d/nginx
注册成服务：chkconfig -add nginx
附上操作指令
service nginx start
service nginx stop
