[root@hui-003 ~]# java -version  

java version "1.7.0_65"  

OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)  

OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)  

（查看了一下我jdk版本是jdk1.7.0，于是就安装java-1.7.0-openjdk-devel.x86_64，后来经试验安装java-1.6.0-openjdk-devel.x86_64和java-1.8.0-openjdk-devel.x86_64后jps命令倒也能正常使用）  

[root@hui-003 ~]# yum -y install java-1.7.0-openjdk-devel.x86_64
