Centos7.0 installed the dubbo cluster and set up automatic startup. After booting, I wanted to use jps to see if zookeeper was started, but an error was reported.
bash：jps 未找到命令...
-bash: jps: command not found
The reason is very simple, java1.5 does not have the jps command, and it is not installed, but the jdk that comes with the system
The solution is to install java and it can be solved, you can check my tutorial
