Subject: problem in using AOLServer and Apache on same machine at
different ports
I am using a Ubuntu virtual machine.Where I installed OpenACS which
depends upon AOLServer.
To do so I had first shutdown Apache on this machine.
Then following instructions given here
http://openacs.org/xowiki/ubuntu
Step 1)
aptitude install postgresql
Step 2)
aptitude install openacs
I had to shutdown Apache to do above installation.
Now the installation finishes.So I can access http://localhost:8000
but when ever I try to start Apache on this machine which was shutdown
during installation I see the error
service apache2 start
* Starting web server apache2 (98)Address already in use: make_sock: couldnot
bind to address 0.0.0.0:80
no listening sockets available, shutting down Unable to open logs
So I thought may be OpenACS installs AOLServer so Aolserver might be
listening on port 80 I check
/etc/aolserver4/conf.d/
openacs.sh
and here
AOL_USER=www-data
AOL_GROUP=www-data
AOL_ADDRESS=192.168.1.15
AOL_PORT=8000
RUN_DAEMON=yes
So AOLServer is not listening on port 80 upto here it is confirmed.
netstat -tualp | grep 80
tcp 0 0 somemachine.somedimain.:8000 *:* LISTEN 21321/aolserver4-ns
so netstat shows only 8000 in use.
Then why am I unable to start Apache in this case?
service apache2 start
* Starting web server apache2 (98)Address already in use: make_sock:
couldnot bind to address 0.0.0.0:80
no listening sockets available, shutting down Unable to open logs
---------------------------------------------------------------------
I was able to solve this problem this is not related to Apache directly but
since I am using apache on same machine and was not able to handle port at which
apache was listening so mentioning a solution so that it helps some one else.
in /etc/default/aolserver4 file
putting RUN_DAEMON=no did the trick.
otherwise inspite of Apache only listening the thing at port 80
Now inspite of port 80 being free when ever I tried to start Apache on this
machine which was shutdown during installation I see the error
service apache2 start
* Starting web server apache2 (98)Address already in use: make_sock: could
not bind to address 0.0.0.0:80 no listening sockets available, shutting down
Unable to open logs
but this solved my problem.Mentioning here so that it helps some one else.
