[slurm-users] "cannot find auth plugin for auth/munge" with slurm-llnl

[Alan Do-Omri]

Hey,

I have been trying to set up slurm for the last few days but I keep stumbling upon the error whenever I run sudo slurmdbd -D:
slurmdbd: error: Couldn't find the specified plugin name for auth/munge looking at all files
slurmdbd: error: cannot find auth plugin for auth/munge
slurmdbd: error: cannot create auth context for auth/munge
slurmdbd: fatal: Unable to initialize auth/munge authentication plugin

When I run sudo slurmd -D, I get the following errors:
slurmd: slurmd version 15.08.7 started
slurmd: error: Error binding slurm stream socket: Address already in use
slurmd: error: Unable to bind listen port (*:6818): Address already in use

I have set up my firewall to accept connections to these ports, however.

When I run sudo sacctmgr -vvvv, I get the following:
sacctmgr: debug3: Trying to load plugin /usr/lib/x86_64-linux-gnu/slurm/accounting_storage_slurmdbd.so
sacctmgr: Accounting storage SLURMDBD plugin loaded with AuthInfo=/var/run/munge/munge.socket.2
sacctmgr: debug3: Success.
sacctmgr: debug2: slurm_connect failed: Connection refused
sacctmgr: debug2: Error connecting slurm stream socket at 127.0.0.1:8080: Connection refused
sacctmgr: debug:  slurmdbd: slurm_open_msg_conn to localhost:8080: Connection refused
sacctmgr: error: Problem talking to the database: Connection refused

In my slurm.conf file I have
SlurmUser=slurm
SlurmctldPort=6817
SlurmdPort=6818
AuthType=auth/munge
AccountingStorageType=accounting_storage/slurmdbd
AccountingStoragePort=6819
AccountingStorageHost=localhost
#AccountingStorageLoc=
AccountingStoragePass=/var/run/munge/munge.socket.2
AccountingStorageUser=slurm
(among other

In my slurmdbd.conf file I have
DbdAddr=localhost
DbdHost=localhost
DbdPort=6819
SlurmUser=slurm
StorageType=accounting_storage/mysql
StoragePass=myslurmpassword
StorageUser=slurm
StorageLoc=slurm_acct_db

and in the MySQL database, I have also done
grant usage on *.* to 'slurm'@'localhost';
grant all privileges on slurm_acct_db.* to 'slurm'@'localhost';
flush privileges;


Slurm was installed using sudo apt install slurm-llnl.

I have done some research to try to solve this problem and I found some solutions but they didn't work for me. Two of them that I found were
1. To install munge development librairies: I have done this by doing sudo apt install libmunge-dev libmunge2
2. Using this https://groups.google.com/forum/#!searchin/slurm-users/unable$20to$20find$20auth$20munge%7Csort:date/slurm-users/Igm-moubmlM/OS26x2mNCAAJ to fix the library locations.

Even after these two solutions, I am unable to fix the problem.

Thank you for your help!
