Tengo problemas con Apache. Acabo de instalar Centos y quiero crear mi propio servidor web. Estoy siguiendo las instrucciones de "el servidor perfecto para centos 7.2" y encontré este error en mi máquina
[root@server01 /]# sudo systemctl start httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

Ahora al ejecutar este comando nuevamente systemctl status httpd.servicesigo encontrando el mismo error.

¿Por qué no aparece el puerto 80 o el puerto 443?
Respuesta1
Ya estás ejecutando algo en el puerto 80. Este comando lo identificará por ti.
sudo netstat -nap | grep ':80 .*LISTEN'
Respuesta2
Yo diría que use nmap para ver qué servicios se están ejecutando y en qué puerto. Un resultado de nmap se parece a esto...
$ nmap 192.168.50.25
...
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http <~ make sure service is http
443/tcp open https
Si algo que no sea http usa el puerto 80, puede cambiar la configuración de Apache y apuntarla a un puerto diferente o cambiar el servicio que usa el puerto 80 a un puerto diferente.Aquí hay una guía para instalar nmap.
Respuesta3
Primero debes usar el comando:
netstat -natup |grep 80
debes informarnos qué servicio se está ejecutando, si otro servicio usa el puerto 80, debes eliminarlo.
Si de esta manera no se puede solucionar el problema, puede verificar el permiso de httpd.conf, debe verificar si tiene el comando:
listen [::]:80
porque podemos saber el error en su syslog
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
En algún momento, este problema es causado por ipv6, por lo que debes agregar el comando en tu configuración.
listen [::]:80 ipv6only=off default_server;
entonces puedes reiniciar el servicio httpd
