新建用户jenkins,并生成秘钥
useradd jenkins su - jenkins ssh-keygen -t rsa cd /home/jenkins/.ssh cat id_rsa.pub >> authorized_keys chmod 600 authorized_keys
cat id_rsa
然后复制秘钥，在jenkins的Credentials中新建一个用户使用秘钥登录，并输入用户名和秘钥，创建节点机
然后启动节点
如果遇到报错【The SSH key for this host is not currently trusted. Connections will be denied until this new key is authorised.】
直接节点配置里面点trust key
