From your output:

no listening sockets available, shutting down

what basically means, that any port in which one apache is going to be listening is already being used by another application.

netstat -punta | grep LISTEN

Will give you a list of all the ports being used and the information needed to recognize which process is so you can kill stop or do whatever you want to do with it.

After doing a nmap of your ip I can see that

80/tcp    open     http

so I guess you sorted it out.

In my case I got the error simply because I had changed the Listen 80 to listen 443 in the file

/etc/httpd/conf/httpd.conf

Since I had installed mod_ssl using the yum commands

yum -y install mod_ssl

there was a duplicate listen 443 directive in the file ssl.conf created during mod_ssl installation.

You can verify this if you have duplicate listen 80 or 443 by running the below command in linux centos (My linux)

grep  '443' /etc/httpd/conf.d/*

below is sample output

/etc/httpd/conf.d/ssl.conf:Listen 443 https
/etc/httpd/conf.d/ssl.conf:<VirtualHost _default_:443>
/etc/httpd/conf.d/ssl.conf:#ServerName www.example.com:443

Simply reverting the listen 443 in httd.conf to listen 80 fixed my issue.

回答3:

on command line type journalctl -xe and the results will be

SELinux is preventing /usr/sbin/httpd from name_bind access on the tcp_socket port 83 or 80

This means that the SELinux is running on your machine and you need to disable it. then edit the configuration file by type the following

nano /etc/selinux/config

Then find the line SELINUX=enforce and change to SELINUX=disabled

Then type the following and run the command to start httpd

setenforce 0

Lastly start a server

systemctl start httpd

I got the same error because of a simple typo in vhost.conf. Remember to make sure you don't have any errors in the config files.

apachectl configtest
