DC/OS快速安裝部署

環境准備

DC/OS 集群

• Master 節點 (選舉)
• Agent 節點
  • Private
  • Public
• Bootstrap 節點

跳板機安裝ansible、mazer並且跳板機到其他4個節點為ssh免密鑰登陸

跳板機安裝ansible、dcos.dcos_ansible、mazer

yum instal -y ansible 
curl https://bootstrap.pypa.io/get-pip.py | python   #安裝pip
pip install mazer==0.4.0      #通過pip安裝mazer
mazer install dcos.dcos_ansible

ansible hosts配置文件

[root@jumpserver ~]# cd /etc/ansible/
[root@jumpserver ansible]# pwd
/etc/ansible
[root@jumpserver ansible]# ls
ansible.cfg  hosts  roles
[root@jumpserver ansible]# cat hosts
[bootstrap]
3.115.184.172
[master]
18.177.76.161

dcos_ansible配置文件

需要注意⚠️以下三個文件

[root@jumpserver dcos-ansible-0.52.0]# cat ansible.cfg
[defaults]
inventory = inventory
host_key_checking = False
remote_user = root ##這個需要是root要不會報錯
forks = 100
hash_behaviour = replace
[ssh_connection]
control_path = %(directory)s/%%C
pipelining = True
ssh_args = -o PreferredAuthentications=publickey -o ControlMaster=auto -o ControlPersist=5m

如果使用ansible部署，這個配置文件不用動

[root@jumpserver dcos-ansible-0.52.0]# cat dcos.yml
