Centos7.0 minimizes installation of nginx source code. the installation process is recorded and cannot be accessed. why?

Centos7.0 minimizes installation of nginx source code. the installation process is recorded and cannot be accessed. why? Newbie wants to download and edit source code directly using wget
After compilation, no response is returned. how can I check whether the function is enabled normally?
View three processes

[root@localhost sbin]# ps -ef|grep nginxroot     13536     1  0 14:14 ?        00:00:00 nginx: master process ./nginxnobody   13537 13536  0 14:14 ?        00:00:00 nginx: worker processroot     13540  2281  0 14:16 pts/0    00:00:00 grep --color=auto nginx

The first one is compiled by me.

The firewall iptables does not limit port 80 either.

I directly access http: // 192.168.1.103/
No.

The IP address is correct.

The article is a bit long. please take a look at it ~ Why haven't I figured it out for several days?

In centos, is there nginx? do you need to uninstall nginx and install nginx first? how can I check it?
Could you please help me to find out how to install yum on the official server?
Or manually compiled?

This seems to have been successful. All processes are available.
You can wget the local IP address on the server to see if the content can be obtained.

Excuse me, is this normal? I have a local area network (LAN) sub-host installed in this way and access the IP address on another machine should be OK?
It seems that the index.html is also found. I directly access http: // 192.168.1.103/on another server, prompting that the server cannot be accessed.
Does the firewall seem to have no rules for port 80?

What else is nginx two processes? Is it normal? please take a look ~ I have been confused for several days ~

If the direct wget IP address is correct

I want to vomit blood quickly. could you please help me see it? why can't I access this machine ~ Is it a Firewall problem? is it correct with the method above ~

Finally Solved ~
