httpd morto mas o arquivo pid existe | httpd morto mas sudsys bloqueado. Centos 6

2

Centos 6 64bit clean install no VPS, qualquer tipo de pacote instalado apenas tentando usar o httpd já instalado.

my case:    
[root@bucch ~]# service httpd status    
httpd is stopped    
[root@bucch ~]# service httpd start    
Starting httpd:                                           [  OK  ]    
[root@bucch ~]# service httpd status    
httpd dead but pid file exists     
[root@bucch ~]# rm -f /var/run/httpd/httpd.pid    
[root@bucch ~]# service httpd status    
httpd dead but subsys locked    
[root@bucch ~]# rm -f /var/lock/subsys/httpd    
[root@bucch ~]# service httpd status    
httpd is stopped    
[root@bucch ~]# tail -n 10 /var/log/httpd/error_log

no /etc/httpd/conf/httpd.conf tem esta diretiva:

PidFile /var/run/httpd/httpd.pid    

e no / etc / sysconfig / httpd tem isto:

PIDFILE=/var/run/httpd/httpd.pid    

no / etc / sysconfig / iptables tem:

-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT    
-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT    

o diretório / var / run / httpd tem esse tipo de permissão:

chmod a+rx    

esta é a saída do netstat -plant que é a mesma antes e depois de iniciar o serviço httpd

[root@bucch ~]# netstat -plant

Enviou uma solicitação de suporte ao provedor de hospedagem e, após 2 dias, corrigiu o problema. O ticket foi fechado com esta mensagem: "Olá, o problema estava no nó, tivemos que fazer uma mudança no kernel do nó."

Agora, com a mesma configuração (e mais pacotes), o Apache está funcionando perfeitamente. Obrigado a todos de qualquer maneira!
