创建slave node的时候执行下面命令，在运行第二条命令后：
curl -sO http://127.0.0.1:8080/jnlpJars/agent.jar
java -jar agent.jar -url http://127.0.0.1:8080/ -secret 6b1f6481fb8bd30bd61a168098d65d2aa10ee38e8f9594c18bc501dcfe7a5b2b -name sky -workDir "/Users/zhangjiangying/Downloads/jenkins_node_sky"

解法：
1、进入此页面：http://127.0.0.1:8080/manage/configureSecurity/
2、把【禁用】改成【随机】

3、保存后再执行刚才的命令，slave node机器部署成功
