安装ansible
yum install ansible -y
修改配置文件，增加节点
vi /etc/ansible/hosts # This is the default ansible 'hosts' file. # # It should live in /etc/ansible/hosts # # - Comments begin with the '#' character # - Blank lines are ignored # - Groups of hosts are delimited by [header] elements # - You can enter hostnames or ip addresses # - A hostname/ip can be a member of multiple groups # Ex 1: Ungrouped hosts, specify before any group headers. ## green.example.com ## blue.example.com ## 192.168.100.1 ## 192.168.100.10 # Ex 2: A collection of hosts belonging to the 'webservers' group ## [webservers] ## alpha.example.org ## beta.example.org ## 192.168.1.100 ## 192.168.1.110 # If you have multiple hosts following a pattern you can specify # them like this: ## www[001:006].example.com [k8s] 192.168.124.61 192.168.124.62 192.168.124.63 [k8s:vars] ansible_ssh_user=root ansible_ssh_pass=123456 ansible_ssh_port=22 # Ex 3: A collection of database servers in the 'dbservers' group ## [dbservers] ## ## db01.intranet.mydomain.net ## db02.intranet.mydomain.net ## 10.25.1.56 ## 10.25.1.57 # Here's another example of host ranges, this time there are no # leading 0s:
配置免密登录
1、生产秘钥
ssh-keygen -t rsa
2、分发秘钥
ansible k8s -m authorized_key -a "user=root key='{{lookup('file','/root/.ssh/id_rsa.pub')}}'"
上传文件

修改文件里面的ip，安装目录等
最新修改：安装网络插件为flannel host-gw模式，采用ipvs。
查看README.md 文件，根据实际路径等进行修改
执行安装命令
单Master版：
# ansible-playbook -i hosts single-master-deploy.yml -uroot -k
查看执行结果
查看etcd
