我们可以看到大部分云服务器商家都开始注重安全方面的设置。我们可以开放需要用到的端口，不用到的端口就直接给不开通或者屏蔽掉，这样可以确保服务器的安全。记得我们在安装阿里云ECS服务器的时候是需要强制选择一个安全组的，早期是不需要的。要么我们就开始自定义一套安全组，要么就先默认后去给当前服务器设置安全组。在这里老左测试服务器中用后者，在配置好ECS服务器之后，我们再去设置安全组。第一、进入安全组....

服务器80端口的问题，安全组放行了，但是80端口还是不能使用

netstat -an | grep 80命令 firewall-cmd --add-port=80/tcp --permanent命令看着返回 success也成功了，80端口就是不能用。
