[Mono-list] Mono 1.9 + mod_mono on Ubuntu - strange problems

[Amc Gmail]

You don't need to upgrade to recent Mono, and i would not recommend it
for start, just to avoid multi-Mono environment configuration issues.
(OK, ok, nothing wrong with multiple-Mono's :-), but I would start
from simple single Mono 1.9, which you do have on Ubuntu 8.10
out-of-the-box).

About XXGLOBAL error on apache restart:
i do have that problem on Ubuntu, but it never cause any trouble.
there is nothing like that on other's like CentOS for example. Sorry,
but i have no solution for that error message, but it seems to be safe
to ignore it.

About apache config:
for Ubuntu 7 & 8.xx to run each site under separate mod-mono-server
instances you can add something like this at the end of
/etc/apache2/sites-available/default:


    #
    # Mono auto-hosting disabled
    #
    MonoAutoApplication disabled

    #
    # Mono control panel
    #
#    <Location /mono>
#        SetHandler mono-ctrl
#        Order deny,allow
#        Deny from all
#        Allow from 127.0.0.1
#    </Location>

    #
    # default mod-mono-server instance to serve everything below host root
    #
    AddMonoApplications default "/:/var/www/"

    #
    # ASPX test in /tst_aspx virtual dir
    # served by tst_aspx mod-mono-server instance
    #
    Alias /tst_aspx "/var/tst/aspx/"
    AddMonoApplications tst_aspx "/tst_aspx:/var/tst/aspx/"
    <Directory "/var/tst/aspx/">
        Options FollowSymLinks
        AllowOverride None
        Order deny,allow
        Allow from all
        MonoSetServerAlias tst_aspx
    </Directory>

    #
    # my_demo application in /my_demo virtual dir
    # served by my_demo mod-mono-server instance
    #
    Alias /my_demo "/var/my/my_demo/site/"
    AddMonoApplications my_demo "/my_demo:/var/my/my_demo/site/"
    <Directory "/var/my/my_demo/site/">
        Options FollowSymLinks
        AllowOverride None
        Order deny,allow
        Allow from all
        MonoSetServerAlias my_demo
    </Directory>

    #
    # my2 application in /my2 virtual dir
    # served by my2 mod-mono-server instance
    #
#    Alias /my2 "/var/my/my_2/site/"
#    AddMonoApplications my2 "/my2:/var/my/my_2/site/"
#    <Location "/my2">
#        MonoSetServerAlias my2
#        SetHandler mono
#    </Location>

</VirtualHost>
