原因是没有Java路径

jenkins】#which Java
/root/soft/jdk1.8.0_101/bin/java

jenkins】#vi /etc/rc.d/init.d/jenkins
找到 candidates ="/etc/...
/usr/.....
/usr/.......
/usr/.....
.........."
引号里面结果插入 /root/soft/jdk1.8.0_101/bin/java

Jenkins】#systemctl daemon-reload
jenkins】#service jenkins start
查看密码
jenkins】#cat /var/lib/jenkins/secrets/initialAdminPassword
