Start AOLserver

Congratulations! You have finished your configuration chores! Now all you'll need to do is start AOLserver and verify that everything is working. First, log in as the user aolserver, run the following command, and hit Ctrl+C to terminate it:

[aolserver@goshawk aolserver]$ bin/nsd -ikt acs-pg.tcl
[23/Apr/2000:15:27:08][629.1024][-t1024-] Notice: nsd.tcl: starting to read config file...
[23/Apr/2000:15:27:08][629.1024][-t1024-] Warning: nsd.tcl: nscp not loaded because
 user/password is not set.
[23/Apr/2000:15:27:08][629.1024][-t1024-] Notice: nsd.tcl: finished reading config file.
[aolserver@goshawk aolserver]$ 

Ignore the warning that nscp was not loaded.

By default, AOLserver will create a log file named log/server.log. Carefully read this log file and look for errors. One common error is forgetting to compile nspostgres.c, the driver for PostgreSQL, or copying the resulting shared object to AOLserver's bin directory and therefore causing the server to fail when it tries to load the driver.

After the server has successfully initialized itself, the example initialization file (included with this article) causes it to load and start OpenACS. The software will try to interrogate a public Web site that lists known Web-crawling and similar robots, and will stuff information about them into a database table in order to refuse their access to portions of your site. If the computer on which you've installed this program isn't connected to the Internet, this will trigger errors that you can safely ignore.

If you have errors and cannot figure out their cause, try the Installation and Configuration help forum at the OpenACS Web site. The experienced users who frequent the site can help you figure out any problems you experience while trying to get this software up and running.

Now that you've inspected the log file and are satisfied that everything is working properly, start AOLserver again and point your browser at port 8000 to the IP you specified when you configured the software. If everything is working correctly, a login page will appear, and you'll be ready to customize your site. This process is described in the second article of this series.
