 Posted: Sun Nov 15, 2015 10:01 pm Post subject: cant start apache [Solved] |
 |
|
Today I had to change the router TP-LINK for ZyXEL. After reboot hostname has changed from localhost to dhcppc1. | Quote: | /etc/host
127.0.0.1 localhost
::1 localhost
|
/etc/conf.d/hostname | Quote: | hostname="localhost"
|
and
| Quote: | # echo $HOSTNAME
dhcppc1
|
| Quote: | # /etc/init.d/apache2 restart
* Starting apache2 ...
* start-stop-daemon: failed to start `/usr/sbin/apache2' [ !! ]
* ERROR: apache2 failed to start
|
I have to say, that I am confused and do not know how to fix it.

| Configure your DHCP client not to pull hostname from DHCP server. Or even better, do not use DHCP at all. |

Let's say solved. Apache works after editing /etc/dhdcpcd.conf
but I am not absolutely satisfied. After connecting to the router HOSTAME is still dhcppcX.
I am not able | Quote: | | Configure your DHCP client not to pull hostname from DHCP server. |
as Buffoon suggested. How to do that? |

Unfortunatelly is not the best solution too. E.g. after rebooting from Windows apache doesnt start. I do not know why. So that I removed apache from startup services and after reboot when I neet to use apache I run | Code: | sysctl kernel.hostname=localhost
/etc/init.d/apache2 start |
But main problem, that ZyXEL assigns hostname of my comp persists. |

Hi apiaio
which dhcp client are you using? There is a pretty big difference between e.g. dhclient and dhcpcd
On the other hand, you can also configure your dhcp server (the ZyXEL AP) to not push the hostname for your internal network

Hi kikko.
Using dhcpcd. Concerning hostname I am not sure if is possible to change ZyXEL's configuration.
But I am sure that must exists the way how to ignore sent hostname.
I have installed Sabayon, which hostname is aswell overwritten by hostname sent by server, but apache starts without any problems. |

I did, but no significant differencies found. Concerning dhcpcd config's files dhdcpcd.conf are the same and others is not compareble becouse my Gentoo uses OpenRC and SL Systemd. |

Hi apiaio
you should try to start httpd daemon directly on the command line, in order to get more "valuable" output
commands are like this:
| Code: | | /sbin/httpd -f /etc/apache2/httpd.conf -t |
Start
| Code: | | /sbin/httpd -f /etc/apache2/httpd.conf -k start |
Check it, I'm not 100% sure about httpd location 
Regards

| for Gentoo that'd be /usr/sbin/apache2 instead of /usr/(s)bin/httpd |

apiaio ... you would do the following:
| /etc/conf.d/net: | | dhcp_eth0="nosendhost" |
... but that isn't really your problem, the issue is that apache can't resolve the FQDN (Fully Qualified Domain Name) ... 'localhost' isn't a FQDN but the name of the 'loopback' (127.0.0.1) ... it also isn't really your 'hostname', every machines loopback is 'localhost'.
| /etc/conf.d/hostname: | | hostname="foo" |
| /etc/hosts: | | 127.0.0.1 foo localhost |
| Code: | # dig +short localhost
127.0.0.1 |
So, you either have apache 'listen' on the loopback ... via changing apache2.conf to 'Listen 127.0.0.1:80', or you provide a FQDN in /etc/hosts, or DNS, (that matches the machines IP).
