Por que o meu servidor Apache não é iniciado automaticamente quando eu reinicio meu servidor?

Question

Estou usando o Amazon Linux. Eu só Apache via yum, no entanto, eu não consigo que ele inicie automaticamente quando eu reiniciar meu servidor, apesar do fato de que ele começa na linha de comando ...

[myuser@mymachine ~]$ sudo service httpd start
[sudo] password for myuser:
Starting httpd: httpd: apr_sockaddr_info_get() failed for mymachine
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
                                                           [  OK  ]
[myuser@mymachine ~]$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Eu configurei estes links abaixo, com as seguintes permissões. O arquivo de configuração foi criado automaticamente para mim na instalação ...

exit $RETVAL

No entanto, após a reinicialização do servidor, as coisas não estão sendo executadas (não consigo me conectar ao Telnet pela porta 80). O que mais eu preciso fazer para que isso comece na reinicialização?

[myuser@mymachine ~]$ ls -al /etc/rc3.d/*httpd*
lrwxrwxrwx 1 root root 15 Oct 18 22:03 /etc/rc3.d/K15httpd -> ../init.d/httpd

Esse é o seu problema. Script que começa com K, que significa kill, em /etc/rc3.d não será iniciado no momento da inicialização, scripts que começam com S.

Se você fizer isso:

[myuser@mymachine ~]$ mv /etc/rc3.d/K15httpd /etc/rc3.d/S15httpd

Seu problema será resolvido. No entanto, essa é a coisa manual a fazer. a melhor maneira seria usar o comando chkconfig da seguinte forma:

[myuser@mymachine ~]$ chkconfig httpd on
