Centos 没有jps命令解决方法

[root@localhost usr]# java -version
openjdk version "1.8.0_222-ea"
OpenJDK Runtime Environment (build 1.8.0_222-ea-b03)
OpenJDK 64-Bit Server VM (build 25.222-b03, mixed mode)

[root@localhost usr]# yum list | grep jdk-devel
java-1.6.0-openjdk-devel.x86_64             1:1.6.0.41-1.13.13.1.el7_3 base     
java-1.7.0-openjdk-devel.x86_64             1:1.7.0.261-2.6.22.2.el7_8 base     
java-1.8.0-openjdk-devel.i686               1:1.8.0.272.b10-1.el7_9    updates  
java-1.8.0-openjdk-devel.x86_64             1:1.8.0.272.b10-1.el7_9    updates  
java-11-openjdk-devel.i686                  1:11.0.9.11-0.el7_9        updates  
java-11-openjdk-devel.x86_64                1:11.0.9.11-0.el7_9        updates  

上述两个可以看见我Java版本的JDK1.8,所以我们就下载1.8的版本

[root@localhost usr]# yum -y install java-1.8.0-openjdk-devel.x86_64

最后输入jps测试

[root@localhost usr]# jps
25077 BrokerStartup
76047 Jps
