新建虛機server6

[root@server6 ~]# curl "https://repository.moosefs.com/RPM-GPG-KEY-MooseFS" > /etc/pki/rpm-gpg/RPM-GPG-KEY-MooseFS
[root@server6 ~]# curl "http://repository.moosefs.com/MooseFS-3-el7.repo" > /etc/yum.repos.d/MooseFS.repo

pacemaker高可用

[root@server1 ~]# vim /etc/yum.repos.d/dvd.repo
[HighAvailability]
name=rhel7.6 HighAvailability
baseurl=file:///media/addons/HighAvailability
gpgcheck=0[root@server1 ~]# yum install -y pacemaker pcs psmisc policycoreutils-python

server6同步?

[root@server1 ~]# scp /etc/yum.repos.d/dvd.repo server6:/etc/yum.repos.d/
[root@server1 ~]# ssh server6 yum install -y pacemaker pcs psmisc policycoreutils-python

節點認證

[root@server1 ~]# systemctl enable --now pcsd.service
[root@server1 ~]# ssh server6 systemctl enable --now pcsd.service[root@server1 ~]# echo westos | passwd --stdin hacluster
[root@server1 ~]# ssh server6 'echo westos | passwd --stdin hacluster'[root@server1 ~]# pcs cluster auth server1 server6
Username: hacluster
Password: westos

創建集群

[root@server1 ~]# pcs cluster setup --name mycluster server1 server6
[root@server1 ~]# pcs cluster start --all
[root@server1 ~]# pcs cluster enable --all

禁用stonith

[root@server1 ~]# pcs property set stonith-enabled=false

ISCSI

server4添加硬盤分區

[root@server5 ~]# yum install targetcli -y
[root@server5 ~]# systemctl enable --now target

[root@server5 ~]# targetcli

創建分區

[root@server1 ~]# fdisk /dev/sdb
[root@server1 ~]# mkfs.xfs /dev/sdb1

[root@server1 ~]# mount /dev/sdb1 /mnt/
[root@server1 ~]# cd /var/lib/mfs/
[root@server1 mfs]# systemctl disable --now moosefs-master.service
[root@server1 mfs]# cp * /mnt/

[root@server1 mnt]# ll -d /mnt/
[root@server1 ~]# umount /mnt/
[root@server1 ~]# ll -d /mnt/

server6類推

[root@server6 mfs]# mount /dev/sdb1 /var/lib/mfs/
[root@server6 mfs]# chown -R mfs.mfs .
[root@server6 ~]# umount /var/lib/mfs/
