[04/11/19 00:49:34] [SSH] Starting agent process: cd "/root/.jenkins" && /home/hc/java/jdk1.8.0_181/bin/java -jar remoting.jar -workDir /root/.jenkins
"-workDir" is not a valid option
java -jar slave.jar [options...]
-auth user:pass : If your Jenkins is security-enabled, specify
a valid user name and password.
-connectTo HOST:PORT : make a TCP connection to the given host and
port, then start communication.
-cp (-classpath) PATH : add the given classpath elements to the
system classloader.
-jar-cache DIR : Cache directory that stores jar files sent
from the master
-jnlpCredentials USER:PASSWORD : HTTP BASIC AUTH header to pass in for making
HTTP requests.
-jnlpUrl URL : instead of talking to the master via
stdin/stdout, emulate a JNLP client by
making a TCP connection to the master.
Connection parameters are obtained by
parsing the JNLP file.
-noReconnect : Doesn't try to reconnect when a
communication fail, and exit instead
-proxyCredentials USER:PASSWORD : HTTP BASIC AUTH header to pass in for making
HTTP authenticated proxy requests.
-secret HEX_SECRET : Slave connection secret to use instead of
-jnlpCredentials.
-slaveLog FILE : create local slave error log
-tcp FILE : instead of talking to the master via
stdin/stdout, listens to a random local
port, write that port number to the given
file, then wait for the master to connect to
that port.
-text : encode communication with the master with
base64. Useful for running slave over 8-bit
unsafe protocol like telnet
Slave JVM has terminated. Exit code=0

分析原因：
大家可以看哦，上面這個設置頁面里面的啟動方式只有Launch Agents Via SSH選項，
而沒有Launch slave Agents Via SSH選項，
最后導致我只選了Launch Agents Via SSH選項和Host Key Verification Strategy的know hosts file version strategy選項。
這樣就會報錯了，不知道為什么新版的Jenkins啟動方式里面沒有Launch slave Agents Via SSH，
但是問題也很好解決！
解決方案：
大家只需要把Host Key Verification Strategy選項改選為Non verifying Vervification Strategy就可以解決這個問題了！
ps:記得java路徑配置到/bin/java 最初的時候我只配置到了bin 一直未成功！
