Hi All,
I have done slurmdbd configuration and while i am trying to run account
manager with *sacct* i am getting below error.
[root at smaster ~]# sacct
sacct: error: slurm_persist_conn_open_without_init: failed to open
persistent connection to host:localhost:6819: Connection refused
sacct: error: Sending PersistInit msg: Connection refused
sacct: error: Problem talking to the database: Connection refused
[root at smaster ~]#
My slurmdbd configuration :
[root at smaster ~]# cat /etc/slurm/slurmdbd.conf
AuthType=auth/munge
DbdAddr=localhost
DbdHost=localhost
SlurmUser=slurm
DebugLevel=4
LogFile=/var/log/slurm/slurmdbd.log
PidFile=/var/run/slurmdbd.pid
StorageType=accounting_storage/mysql
StorageHost=localhost
StoragePass=password
StorageUser=slurm
StorageLoc=slurm_acct_db
[root at smaster ~]# chown slurm: /etc/slurm/slurmdbd.conf
[root at smaster ~]# chmod 600 /etc/slurm/slurmdbd.conf
[root at smaster ~]# mkdir /var/log/slurm
[root at smaster ~]# touch /var/log/slurm/slurmdbd.log
[root at smaster ~]# chown slurm: /var/log/slurm/slurmdbd.log
[root at smaster ~]# scontrol show config | grep AccountingStorageHost
AccountingStorageHost = localhost
Note:
i have edited file /etc/slurm/slurm.conf and modified the below line
# LOGGING AND ACCOUNTING
AccountingStorageType=accounting_storage/slurmdbd
Then restarted all the services
[root at smaster ~]# for i in munge slurmd slurmctld slurmdbd; do service $i
status; done
