1、在MAC上安装 jdk 记录下安装位置（例如我的 /Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home/bin/java），并且开启 ssh（开启后，用ssh工具连接测试一下确认可以正常登录）
2、在MAC的用户目录下创建文件夹 jenkins，例如：/Users/rd-ios/jenkins，并且设置这个目录为可读写权限
3、在MAC电脑上配置共享
4、在Jenkins（master）按如下执行命令
ssh-keygen
cd .ssh
cat id_rsa.pub > authorized_keys
chmod 700 authorized_keys其中 cd .ssh 要看清楚你执行完第一步后的 .ssh 的位置（第一步命令，直接全部回车就行）
下面是我的执行日志：
jenkins@jenkins-jenkins:/$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/jenkins_home/.ssh/id_rsa):
Created directory '/var/jenkins_home/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:

记得展开高级填写jdk位置，例如我的位置是 /Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home/bin/java
其他一些错误，我参考了文章
