Online Scrapped meal, did not get the last to see the error message, or with the relevant java path, which referred to the type - p java, saying this will return the actual path of java, I enter the command line type - p java, return / usr / local / jdk1.8.0_192 / bin / java. This is my installation path of java.
And then return to the startup file vi /etc/init.d/jenkins, find the line JAVA = `type -p java`, I direct this comment line, and then add a line JAVA = /usr/local/jdk1.8.0_192/bin / java, save and exit.
Restart systemctl restart jenkins.service
view the status systemctl status jenkins.service
success.
Then enter the 8888 port the browser to see an old man!
