I have installed a fresh copy of Centos 7. Then I restarted Apache but the Apache failed to start. I have 3 days stucked in this issue. Even the support can not figure out the error.
sudo service httpd start
Failed to start apache :
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

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

ServerAlias YOURDOMAIN.COM

Some other service may be using port 80: try to stop the other services: HTTPD, SSL, NGINX, PHP, with the command sudo systemctl stop and then use the command sudo systemctl start httpd
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.
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
Allow Apache Through the Firewall
Allow the default HTTP and HTTPS port, ports 80 and 443, through firewalld:
sudo firewall-cmd --permanent --add-port=80/tcp
sudo firewall-cmd --permanent --add-port=443/tcp
And reload the firewall:
sudo firewall-cmd --reload
