问题

阿里云新申请的云主机，curl本地哪个端口都会报这个错误：

[root@iZ2zefh0wozglk2v3bmffvZ rocketmq]# curl 0.0.0.0 12581
curl: (7) Failed connect to 0.0.0.0:80; Connection refused
curl: (7) Failed to connect to 0.0.49.37: Invalid argument

解决方案：

安装并启动httpd服务即可

yum install httpd
systemctl enable httpd
systemctl start httpd
