Forum Problems Installing LAMS: Re: Fail to run LAMS 2.2 (win vista, wampserver)

Hi Luke,
thanx for your help. I now WORKS :)

Indeed there was the mysql missing table issue (btw. I noticed that it was missing also in a Solaris distro). But somehow before I posted my initial post I managed to fix this. Don't recall how, maybe just by using 'mysqlcheck'. Anyhow the tables were there and MySQL was running and accessible. Also I had to move the "transaction-isolation=READ-COMMITTED" to an other section.
Summary: I did not have a "MysQL is not available" problem, since all the 202 lams tables were created by your installer.

I rather think that there is a VISTA problem somewhere, also maybe in addition not rebooting after playing with other software may have interfered.
Anyhow, after reboot + a complete deinstall/reinstall of LAMS (but keeping the mysql tables) the start script still WILL NOT work.

**** What did work was the following:
Open the services panel of Vista, click on LAMSv2 and start the service did the trick.

Don't know how it can be found on an English speaking win. Something like: Configuration Panel->Administration tools->Services. I made a shortcut now ;)

I don't want to totally de-install everything to reproduce everything. Currently on my Vista, what does work is the menu "Stop Lams" script. Starting it again still gives the "MySQL doesn't appear running ... " error. But if I start the service with the services panel it will restart again.

- Daniel :)
PS: So I am happy enough, I only needed LAMS on my travel computer. But maybe you should put this on a "let's check Vista with WAMPS" todo list .....

Hi Daniel,

Im glad it worked out for you in the end, I will definately put this on the todo list, especially the issue with the startup script. This will most probably be fixed by the next release. Also, I expect there will be some specific instruction put on the wiki for installing LAMS with WAMP bundled mysql.

Thanks for your help in pointing out the problem

Hello Luke. I am running a Vista Business machine with Wamp 2.0. I installed LAMS 2.2 last night and everthing went very well. I was very impressed. I toyed around with the interface creating users and Groups etc. without any issues. This morning I went to work creating a course with lessons. I got about three noticeboards with lesson one setup and then LAMS totally locked up. The my CPU was maxed out along with the RAM and I couldn't save my work. I backed out of LAMS restarted my computer and then couldn't log in at all. Firefox cannot connect to localhost:8080 was the error. No matter what I tried nothing worked. I ended up uninstalling LAMS and reinstalling with the port setting of 8180. Now LAMS will just sit there waiting on localhost with no activity. Not sure where to go from here. I really was impressed out of the box with this application but now I'm worried I may have to start my search again. Please advise.

Thank
Tsalagi

Correction: I installed LAMS 2.3

I uninstalled LAMS again and this time chose to remove the database and all files. I checked the status of the servers table in mysql and it exised already. I reinstalled LAMS and was able to log in after a terribly long wait for it to load. We'll see how it goes now.

On a side note: The lesson I was creating deals with PHP code and I was having trouble with some tables that had increment and decrement Operators displayed. Could the use of these PHP references cause any problems? For example -- decrement -- $var and ++ increment ++ $var was in the table that I was having trouble with. Just a thought.

Thanks for your help

Hi,

This could be an issue with memory settings but its hard to say without looking at the logs. Could you please zip up the jboss-4.0.2/server/default/log directory and post it here, perhaps we can find the issue in there.

Here you go. Let me know what you find out. When you say memory settings, do you mean with a mysql configuration file? I appreciate any info you can give. I'm trying to get these lessons out an available. I'd hate to have the database become corrupt due to me doing to much at one time.

Hi,

I dont see anything in the logs indicating an error, if LAMS ran out of memory and crashed there would be an indication in the logs. I dont think there is much risk of your database becoming corrupt.

When I say memory settings, I mean the LAMS startup memory settings, which should be ok so long as you didnt change them.

Are you running anything else on your machine? LAMS requires 512MB of ram to run and can become slow if there are too many other things running on the server.

512mb! Yikes! I only have 1 gig of ram but I have my virtual memory kicked up to about 2 gigs. I usually have Notepad++ and several tabs opened in Firefox along with the Wamp Configuration. I may need to remember to clear my clipboard as I am copying and pasting much of my material from web pages I've created. I really appreciate your help. Onward and Upward!

By the way is there any Documentation about using inline styles in the noticeboards? I've used some in my lessons and they work great I just haven't seen any mention of it.

Thanks again

There is alot of information about our html editor (called the fckeditor) here:

Im not sure how much there is about inline css, but im sure you can find more from the fck user guide which you can find a link on the page above.

Here we go again. I was creating another lesson this time I was adding multiple choice questions and LAMS locked up when trying to save the questions. Here are the log files. I'm still thinking that it may be the PHP code I'm including. This time the questions were about arrays with examples of the array syntax and the code array() was one of the answers. Fortunately I was able to log back in. Here are the log files again if you think they will help.
I appreciate your time.
