Opensim runs much better using an up-to-date Mono version, especially on 64 bit servers, you should update Mono on your computer to use the latest Mono version. Snoopy shows you how.
Installing Mono
Use the following installation guide: http://osgrid.org/forums/viewtopic.php?f=14&t=475
First compile and install "mono" and then "libgdiplus". "msc" is
compiled and installed together with the "mono" package. That is
the reason why both need to be installed in the same directory.
Because the current Mono trunk version has the version number 2.5,
I use a prefix directory name for my installation without a version
number ("-prefix=/home/opensim/bin/mono").
Then add the following lines to your ~/.bashrc configuration
file (change the paths if required):
# Mono 2.5
export PATH="/home/opensim/bin/mono/bin:$PATH"
export
PKG_CONFIG_PATH="/home/opensim/bin/mono/lib/pkgconfig:$PKG_CONFIG_PATH"
export MANPATH="/home/opensim/bin/mono/share/man:$MANPATH"
export MONO_THREADS_PER_CPU=80
The value of MONO_THREADS_PER_CPU is important for the stability
of Opensim. If you experience crashes during Opensim startups,
especially for regions with many scripts, try lower and higher
numbers. 80 works best on my Intel Xeon 3200 quadcore servers.
Start a new command window and enter "mono -V". Now it should
show the Mono version number 2.5.
Installing MySQL Database
It is recommended use MySQL as database for Opensim on Linux
servers, where I use separate database catalogs per region. Install
MySQL as described for your Linux distribution. Optimize the MySQL
configuration files as described here: http://osgrid.org/forums/viewtopic.php?f=9&t=119
In the MySQL configuration file you can specify a different
directory (datadir) to store MySQL databases. For example I store
all MySQL databases under /home/mysql/. If you intend to change the
data directory, you should have a look at the following page,
especially if AppArmor is also installed on your computer: http://ubuntuforums.org/showthread.php?t=831147
You need to check if the permissions of the new data directory
and files are set properly to the user and group "mysql" and that
this user has read and write rights, otherwise MySQL will show an
error message during startup.
MySQL Administrator (mysql-admin) and MySQL Query
Browser (mysql-query-browser) are good tools to administer
MySQL databases. I use these MySQL tools also to create new
database catalogs for new regions, where I use the same names as
the region names; and to fix problems in the database that from
time to time can be caused by bugs in Opensim. For such fixes you
need some understanding of the Opensim database structure (see http://opensimulator.org/wiki/Database_Schema).
If you get "access denied" error messages, when you try to use
these tools, especially when MySQL is installed on another
computer, you should have a look at this web page: http://dev.mysql.com/doc/refman/5.0/en/access-denied.html
