背景

服务器的jdk通过yum 安装的，要用jps查询pid，提示找不到命令

yum install -y java-1.8.0-openjdk.x86_64

一、jps命令无法找到

$dev@hgh-tob-hsbc-dev-003 \~$ $ jps

-bash: jps: command not found

二、检查基础Java环境

$dev@hgh-tob-hsbc-dev-003 \~$ $ java -version

openjdk version "1.8.0_292"

OpenJDK Runtime Environment (build 1.8.0_292-b10)

OpenJDK 64-Bit Server VM (build 25.292-b10, mixed mode)

三、查Java安装的目录

$root@hgh-tob-hsbc-dev-003 java$ # which java

/bin/java

$root@hgh-tob-hsbc-dev-003 java$ # ls -lrt /bin/java

lrwxrwxrwx 1 root root 22 May 4 2023 /bin/java -> /etc/alternatives/java

$root@hgh-tob-hsbc-dev-003 java$ # ls -lrt /etc/alternatives/java

lrwxrwxrwx 1 root root 73 May 4 2023 /etc/alternatives/java -> /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-1.el7_9.x86_64/jre/bin/java

四、安装目录无jps命令

五、需要安装openjdk-devel包

yum install -y java-1.8.0-openjdk-devel.x86_64

六、安装后执行结果

$root@hgh-tob-hsbc-dev-003 bin$ # jps

52391 Jps
