lsapi and PLESK

eek · Oct 19, 2007

Hi there,

I was wondering whether it is possible to use ruby-lsapi (or respectfully php-lsapi) for domains managed via PLESK?

thanks in advance for answer

Andrej

mistwang · Oct 19, 2007

Yes, there should not be any problem. Actually, LSAPI is the only recommended option for RoR and PHP support.

eek · Oct 19, 2007

Hi,

is there anything specific that needs to be set up fore example: putting dispatch.lsapi into indexes etc.. except for these steps ?

1. create domain in PLESK (check PHP support for PHP?)
2. set LS to use apache config
3. should I remove the default listener for port 80 ? since LS will create listeners for all vhosts_ip

ort combinations.

note that apache is not running.

thank you!

Andrej

mistwang · Oct 19, 2007

Yes, you need to remove the listener for port 80.
For RoR setup, should use this

http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:rails_hosting

however, it is Enterprise edition only.

mistwang,

i can't seem to get the shared rails hosting to work.

vhost config:

Code:

DocumentRoot /home/httpd/vhosts/....../httpdocs

.ls_rails_config - location in the vhost root above

Code:

#RailsApp <name> <App Path> <Rails Evn> <Children Processes> <RunOnStart>
RailsApp nlcman "/current" "development" 2 1

#RailsAppMap <name> <domain> <URI>
RailsAppMap nlcman "nlcman.newline-projects.com" "/"

the shared rails hosting is enabled, with no values for the two Max variables

Apache Port offset is 1 so LS is listening on 81.

when i navigate to nlcman.newline-projects.com:81 i got a static page served

do i need to setup any external apps, script handlers, or add mime type (like for php) ?

there is not a sign of a rails host in the logs

thank you for the help

Andrej

eek · Oct 23, 2007

forgot to add that the rails app is in the .../httpdocs/current/ directory

mistwang · Oct 23, 2007

With Apache configuration, the user's home directory set in /etc/password is used as vhost root, not the document root set in the httpd.conf.

eek · Oct 23, 2007

by user you mean the user that was defined during setup?

mistwang · Oct 23, 2007

No, the user that owns httpdocs.

eek · Oct 23, 2007

still nothing

i'm clueless

eek · Oct 23, 2007

vhost docroot:

Code:

/var/www/vhosts/newline-projects.com/subdomains/nlcman/httpdocs

owner of the dir above:

Code:

nlcprojects:psaserv

owners's home dir:

Code:

/var/www/vhosts/newline-projects.com

.ls_rails_config location:

Code:

/var/www/vhosts/newline-projects.com/.ls_rails_config

.ls_rails_config contents:

Code:

#RailsApp <name> <App Path> <Rails Evn> <Children Processes> <RunOnStart>
RailsApp nlcman "/subdomains/nlcman/httpdocs/releases/20071018155320" "development" 2 1

#RailsAppMap <name> <domain> <URI>
RailsAppMap nlcman "nlcman.newline-projects.com" "/"

this is the setup

mistwang · Oct 23, 2007

The configuration looks all right, anything logged into lsws/logs/error.log about "nlcman"?

eek · Oct 23, 2007

hmmm this is weird.

i tried to setup a rails vhost in the lsws admin. so i could see whether at least that works.

the railsrunner is up and running but i only get 500 error..

and the application works just fine with mongrel and apache - i just checked

mistwang · Oct 24, 2007

The 500 error is generated by Rails.
Maybe something is missing for the LSAPI rail setup, missing environment variables, etc. Please check rails log files.

eek · Oct 24, 2007

right, there was a problem with permissions for session file, ok so LS vhost works fine as does the lsapi.

now why doesn't the .ls_rails_config work

mistwang · Oct 24, 2007

can confirm that /var/www/vhosts/newline-projects.com is the home directory of nlcprojects in /etc/passwd?
the .ls_rails_config should be owned by nlcprojects user and the user that lshttpd run as should have read permission.

The related configuration under "server"->"Ruby" tab has been set properly.

eek · Oct 24, 2007

ok i double checked everything and everything seems to be configured properly.

cat /etc/passwd | grep nlcprojects

can this has something to do that we are using the enterprise version with the trial license?
