Slurmd 无法启动，出现以下错误 : fatal: Unable to determine this slurmd's NodeName

Question

我正在尝试在一堆 aws 实例上设置 slurm，但是每当我尝试启动头节点时，它都会给我以下错误:
致命:无法确定此 slurmd 的节点名称
我已经设置了实例/etc/hosts，因此它们可以作为 node1-6 相互寻址，而 node6 是头节点。这是 node6 的 hosts 文件，所有其他节点都有一个类似的 hosts 文件。
/etc/hosts 文件:

127.0.0.1 localhost node6

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

<Node1 IP> node1
<Node2 IP> node2
<Node3 IP> node3
<Node4 IP> node4
<Node5 IP> node5

/etc/slurm-llnl/slurm.conf:

###############################################################################
#                 Sample configuration file for SLURM 2
###############################################################################
#
# This file holds the system-wide SLURM configuration. It is read
# by SLURM clients, daemons, and the SLURM API to determine where
# and how to contact the SLURM controller, what other nodes reside
# in the current cluster, and various other configuration information.
#
# SLURM configuration parameters take the form Keyword=Value, where
# at this time, no spacing is allowed to surround the equals (=) sign.
# Many of the config values are not mandatory, and so may be left
# out of the config file. We will attempt to list the default
# values for those parameters in this file.
#
# This simple configuration provides a control machine named "laptop"
# to run the Slurm's central management daemon and a single node
# named "server" which execute jobs. Both machine should have Slurm
# installed and use this configuration file. If you have a similar
# configuration just change the values of ControlMachine, for the
# control machine and PartitionName and NodeName for job execution

问题在于你

ControlMachine=node6

用“hostname -s”的结果替换 node6。还要像“ifconfig”一样指定ip

ControlAddr=<your local ip>
