Error Plesk: 0.0.0.0:80 failed (98: Address already in use)
Después de toda actualización “gorda” de Plesk me llevo una sorpresa, normalmente no muy agradable. En este caso ha sido un cambio de versión que me ha dejado las webs fuera de servicio.
La gestión de plesk no ha dado ningún problema, de hecho el procedimiento es muy sencillo, pero como digo, mi servidor Centos daba errores por todos lados.
Lo primero que suelo hacer, porque siempre van por ahí los tiros, es comprobar los servicios MYSQL y NGINX.

Y como no podía ser de otra forma, es NGINX el que me da el error. Ya comento que casi siempre es el problema. Quizás por mi integración con Varnish+Apache+Nginx+Mysql:

Parece que algo está utilizando el puerto 80 y 443 que NGINX debería utilizar. Así que reviso qué puede ser:

Matamos los procesos que interfieren con NGINX, en este caso VARNISH
|
1 2 3 4 |
[root@servidor-1 ~]# fuser -kivn tcp 80 USER PID ACCESS COMMAND 80/tcp: varnish 18837 F.... varnishd Kill process 18837 ? (y/N) y |
Y arrancamos los servicios nuevamente, esta vez sin problemas:
|
1 2 3 4 5 6 7 8 |
[root@servidor-1 ~]# service nginx start Starting nginx (via systemctl): [ OK ] [root@servidor-1 ~]# service varnish start Redirecting to /bin/systemctl start varnish.service [root@servidor-1 ~]# service httpd start Redirecting to /bin/systemctl start httpd.service |
Espero que os sirva como a mi esta solución.
