Nemrun for SteamCMD Linux

So, a few people have been bugging me to release my updated version of Nemrun for SteamCMD... so here it is.

This is based on Nemrun 1.8.7.

The new (required) parameters are actually the same ones the server uses with its newer -autoupdate support:
-steam_dir - The directory steamcmd lives in. Replaces -steamdir which was for hldsupdatetool.
-steamcmd_script - The steamcmd script to run. Relative paths are treated as relative from the steam_dir.

Note: This includes srcdsupdatecheck from Nemrun 1.8.7.

Edit: I wonder if the reason Nephyrin didn't update this for SteamCMD himself is because he now works for Valve.

Thank you again. Totally rocks.

Re: Nemrun for SteamCMD Linux

Does anyone have any clue why SteamCMD won't update steam.inf on my servers? (That's plural, it's happening on all three systems). steam.inf won't update with the new version number so nemrun never restarts the servers to update.

Re: Nemrun for SteamCMD Linux

I just realized that I never gave my solution...

SteamCMD wasn't updating my steam.inf file so nemrun never thought the server was fully updated. To fix it, I had to switch my user-relative path (~/tfserver) to an absolute path (/home/user/tfserver).

Re: Nemrun for SteamCMD Linux

Two things:

I just noticed the first post had the command listed as -steamcmd_runscript. It's actually -steamcmd_script.

I also want to post the command lines I use with nemrun_steamcmd to give people an idea of how it works, at least if you use it in its update daemon mode.

For TF2, my update daemon is running like this:

Code:

#!/bin/bash

# Source Dedicated Server Init Script for Nemrun



# Server options

NAME='updater'                          # Server handle for the screen session

STEAM='/home/tf2/tf2'             # Path to STEAM installation

USER='tf2'



STEAM_DIR='../steamcmd'

STEAMCMD_SCRIPT='tf2update.txt'

SHARED_SCREENS='tf2'

cd $STEAM



screen -d -m -U -S $NAME ./nemrun-steamcmd \

-nemlog "runlogs/updater_%Y%m%d%H%M%S.log" \

-cleandownloads 10 -autoupdate -steam_dir $STEAM_DIR \

-steamcmd_script $STEAMCMD_SCRIPT -sharedscreens $SHARED_SCREENS -updatefirst \

\

-game tf -updatedaemon

My game server is running like this:

Code:

#!/bin/bash

# Source Dedicated Server Init Script for Nemrun



# Server options

NAME='tf2'                              # Server handle for the screen session

DAEMON='srcds_run'                      # The server daemon

STEAM='/path/to/server'            # Path to STEAM installation

# Game options

MOTDFILE='motd-halloween'



cd $STEAM



# Server options string

screen -d -m -U -S $NAME ./nemrun-steamcmd \

-nemlog "runlogs/tf2_%Y%m%d%H%M%S.log" \

-corefile "cores/tf2_%Y%m%d%H%M%S.core" \

\

$OPTS

Note that cleandownloads is actually broken at the moment... I need to take the time to fix it at some point.

Re: Nemrun for SteamCMD Linux

Is this still supported (meaning does it work) and err does it have all the features that the original Nemrun with running multiple servers off 1 installation and auto updating...?

Re: Nemrun for SteamCMD Linux

Hi,

where is emailTheAdmins.sh and notifyadmins.sh?

Not sure how I never replied to this, but this should still be operational and I still use it on my Linux TF2 server.

Those have never actually been shipped with NemRun... you actually have to write them yourself.

There are reasons for this...
1. notifyadmins.sh doesn't specify how to contact the admins.
2. emailTheAdmins.sh would need to be written differently depending on how your server is set up... if it has a sendmail binary (installed by most mail servers) it could use that, but otherwise it'd have to talk SMTP directly with a remote mail server.

Also, just because it has a .sh extension doesn't strictly mean it's a shell script... it could be written in perl or python and passed the perl/python interpreter on the first line (the shebang line).

Nemrun is Linux only.

To be clear, I didn't write Nemrun (Nephyrin did that), I just updated it to work with SteamCMD.

Re: Nemrun for SteamCMD Linux

In the example there is some use of taskset. Can you explain how this works and if there is any use to it?

taskset is used to control which cores a server can use. It can be handy if you're running multiple servers from the same machine.

However, by the same token, TF2 and DOTA's replay systems can do things on other threads, so limiting those to a single CPU forces it to do that processing on the same CPU core.

Side note: CPU cores are 0-numbered, so a 4 core processor has cores 0-3. Of course, to specify core numbers, you use the -c argument to taskset... it's a lot easier than using bitmasks.

Except I looked at it at a time where I had a headache.

OK, here's my current test server configuration. Note that it could probably be optimized more by making the server use sv_shutdown to do a delayed restart instead of its normal shutdown command.

Spoiler

tf2_updater.sh:

Code:

#!/bin/bash

# Source Dedicated Server Init Script for Nemrun



# Server options

NAME='updater'                          # Server handle for the screen session

STEAM='/home/tf2/tf2'             # Path to STEAM installation

USER='tf2'



AFTERCMD=/home/tf2/tf2_copyso.sh



STEAM_DIR='../steamcmd'

STEAMCMD_SCRIPT='tf2update.txt'

SHARED_SCREENS='tf2'

cd $STEAM



screen -d -m -U -S $NAME ./nemrun-steamcmd \

-nemlog "runlogs/updater_%Y%m%d%H%M%S.log" \

-cleandownloads 10 -autoupdate -steam_dir $STEAM_DIR \

-steamcmd_script $STEAMCMD_SCRIPT -sharedscreens $SHARED_SCREENS -updatefirst \

-afternotifycmd $AFTERCMD \

-game tf -updatedaemon

-afternotifycmd is something I recently added to make a copy of server_srv.so for plugin development reasons. It occurs after the update completes.

I've considered adding a -sharedkillcommand "sv_shutdown_timeout_minutes 10; sv_shutdown; sm_csay \"Server will shut down in 10 minutes due to update\"" instead of doing an instant restart, but haven't tested it.

Now, the actual server, prophunt_server.sh:

Code:

#!/bin/bash

# Source Dedicated Server Init Script for Nemrun



# Server options

TITLE='Source Dedicated Server'         # Script initialization title

LONGNAME='Team Fortress 2'              # Full title of game type

NAME='tf2'                              # Server handle for the screen session

DAEMON='srcds_run'                      # The server daemon

STEAM='/home/tf2/tf2'            # Path to STEAM installation

USER='tf2'



# Game options

IP='1.2.3.4'                      # IP of the server

PORT='27015'                            # Port number to use

MAP='ph_lumberyard_a2'

MAPCYCLE='mapcycle-prophunt.txt'

GAME='tf'                               # Game type (tf|cstrike|valve|hl2mp)

SIZE='24'                               # Maximum number of players

CONFIGFILE='server-prophunt.cfg'        # Config file to use in cfg directory

REPLAYDIR='blu'                         # Replay subdirectory for this server

CORES='1-3'                             # CPU cores to use

SOURCEMOD='addons/sourcemod-prophunt'

MOTDFILE='motd-prophunt'

AUTOEXEC='autoexec_normal.cfg'

cd $STEAM



# Server options string

# OPTS="-game $GAME +hostname \"$TITLE\" +randommap -ip $IP -port $PORT \

OPTS="-game $GAME +hostname \"$TITLE\" +map ${MAP} -ip ${IP} -port ${PORT} \

    +maxplayers ${SIZE} +sv_pure 1 +mapcyclefile ${MAPCYCLE} \

    +servercfgfile ${CONFIGFILE} -strictportbind +sm_basepath $SOURCEMOD \

    +motdfile ${MOTDFILE}.txt +motdfile_text ${MOTDFILE}_text.txt \

    +exec ${AUTOEXEC}"

#    -replay"



# screen -d -m -U -S $NAME $STEAM/$DAEMON $OPTS



screen -d -m -U -S $NAME ./nemrun-steamcmd \

-nemlog "runlogs/tf2_%Y%m%d%H%M%S.log" \

-corefile "cores/tf2_%Y%m%d%H%M%S.core" \

\

$OPTS

The important part of this script is the part at the end, but I included the entire thing just to make sure I didn't forget anything. The NAME should match the SHARED_SCREENS from the first script. Note that SHARED_SCREENS is a comma-separated list of all TF2 servers you want to restart.

Re: Nemrun for SteamCMD Linux

Can I have an example of a 'unified' steamCMD script?

Because currently I use something like...

vsh_dis.txt

Code:

@ShutdownOnFailedCommand 1

@NoPromptForPassword 1

login anonymous

force_install_dir ../vsh

app_update 232250 validate

exit

And there's another one for each of my other two servers that only changes the folder.

Also I'm just going to assume one first executes 'tf2_updater.sh' and then 'prophunt_server.sh' or 'whatever.sh' for all of one's servers?

And from there this thing handles autoupdating them... or not going through a full file check if there's no need to?

Also... I don't see anything that shuts down the server in what you posted? No kill or quit or exit or restart or shutdown command seems to be in the snippet you posted.

Chdata awaits the day his question is answered clearly.

nemrun is intended to be used with screen. The -sharedscreens argument is a comma-separated list of named screens (-S in the screen command-line) that it should send a "quit" command to. Since these screens were presumably also started with nemrun, they will auto-restart when they get the quit command.

Do note that it's possible to run a custom shell script instead using the -shutdownscript command-line argument or change which command is sent to servers using -sharedkillcommand .
