− | == Region Init Script ==
| + | #REDIRECT [[Startup_script_linux]] |
− | The following is an init script that I wrote for starting, stopping, and monitoring OpenSim on Linux systems. It makes some assumptions, and is only going to work (unmoddified) if you stay with those assumptions:
| + | |
− | * Your opensim instance is in /opt/opensim/staging/bin (that's an easy change)
| + | |
− | * You are only running 1 OpenSim.exe process per machine (that's '''not''' easy to change)
| + | |
− | * You are using mysql (that's easy to change)
| + | |
− | * Production mono is in /usr/local/bin (that's easy to change)
| + | |
− | While it may not be suitable for all environments, it has been very useful for the environments that I run.
