Debian Stable with Apache 2.0.54 (Dreamhost dedicated server)
I'm kind of stuck here and need some fresh ideas. Sorry if this is a
bit long.
I have a front/back (reverse proxy) server setup. I have an init.d
script that starts both servers.
The front end server listens on ports 82 and 1443 (SSL), and reverse
proxies to ports 10082 and 11443 on the back end server.
Upon a reboot only the back-end server starts. The front end server
exits with the error saying it cannot bind to port 1443. Here's what
I see in my boot log:
Cannot assign requested address: make_sock: could not bind
to address 208.97.158.169:1443
no listening sockets available, shutting down
Unable to open logs
Why can't it bind to port 1443? Because the port is inuse? But it
doesn't seem to be in use.
So I run iptables and netstat right before and right after trying to
start Apache, but I don't see anything that would prevent binding to
port 1443. See logs below.
So what's preventing Apache from binding to that port?
Now, if right after I boot I go in and run the init.d script manually
the server starts up without any problem. I.e.:
sudo /etc/init.d/ifp_httpd start
Then the front end server starts and binds to port 82 and 1443.
The init.d script starts late in the boot process:
$ ls -1 /etc/rc2.d/ | tail
S21quotarpc
S23ntp-server
S25mdadm
S30sysctl
S89cron
S91ifp_httpd <<<<<---- here's the init.d script
S99jabber
S99stop-bootlogd
S99ud
Here's the log where I run netstat -ntlp, netstat -ntp, iptables -L
right before and right after starting apache for both the front and
back servers. You can see there's nothing listening or using port
1443.
The script first (attempts) to start the "front" server on ports
82/1443. Then it starts the "back" server on the high ports.
Before doing this in both cases netstat and iptables is run.
