centos下安装munge
控制节点node16
计算节点node16,node18
删除安装失败的munge
yum remove munge munge-libs munge devel -y
userdel -r munge
userdel: user munge is currently used by process 23785
kill 23785
userdel -r munge

新建用户
export MUNGEUSER=991
groupadd -g $MUNGEUSER munge
useradd -m -c "MUNGE Uid 'N' Gid Emporium" -d /var/lib/munge -u $MUNGEUSER -g munge -s /sbin/nologin munge

安装munge
先装epel库:
yum install epel-release

再开始安装munge:
yum install munge munge-libs munge-devel -y

安装rng工具:
yum install rng-tools -y
rngd -r /dev/urandom

在控制节点上新建秘钥并设置权限:
/usr/sbin/create-munge-key -r
- 1
dd if=/dev/urandom bs=1 count=1024 > /etc/munge/
chown munge: /etc/munge/
chmod 400 /etc/munge/

将生成的秘钥发送到计算节点:
(注意node18要在root用户下,并且node16和node18的/etc/hosts文件需要配置ip和snode对应)
scp /etc/munge/ root@snode18:/etc/munge
- 1
到计算节点上改权限:
chown -R munge: /etc/munge/ /var/log/munge/
chmod 0700 /etc/munge/ /var/log/munge/

systemctl enable munge
systemctl start munge

测试munge是否装好:
munge -n
munge -n | unmunge
munge -n | ssh 3.buhpc.com unmunge
