Server just upgraded from Squeeze to Wheezy. After reboots, I noted that apache2 wasn't starting, so installed bootlogd to inspect the output of init scripts.
The error output from apache start was,
Tue Feb 3 08:49:55 2015: [....] Starting web server: apache2(99)Cannot assign requested address: make_sock: could not bind to address [0123:4567:890:abc::d]:80
Tue Feb 3 08:49:55 2015: no listening sockets available, shutting down
Tue Feb 3 08:49:55 2015: Unable to open logs
Tue Feb 3 08:49:55 2015: Action 'start' failed.
Tue Feb 3 08:49:55 2015: The Apache error log may have more information.
Timestamps in the boot output show 4s between "Configuring network interfaces" (08:49:51) and starting apache.
I've worked around this by inserting a sleep 5 into /etc/init.d/apache2 after which apache2 starts fine, so I'm reading it as slow network initialization (possibly specific to IPv6 networking). The server is running on VMWare, and I have access only to the VM.
- What better methods could I use to make Apache wait a few seconds and check its addresses are up and running before start?
- Or to make the network init script not exit until the addresses are ready?
