Changing password for user hacluster.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
# ssh pcmk-2 -- 'echo mysupersecretpassword | passwd --stdin hacluster'
# pcs host auth pcmk-1 pcmk-2
### 此处为host非cluster
# pcs cluster setup mycluster \
pcmk-1 addr=192.168.122.101 pcmk-2 addr=192.168.122.102
### setup没有--name选项
#pcs cluster start --all
# systemctl start corosync.service
# systemctl start pacemaker.service
# pcs status验证安装完成
# journalctl -b | grep -i error排错
