Linux 卸载OpenJDK

1、查询jdk版本

java -version
结果如下：

openjdk version "1.8.0_312"

OpenJDK Runtime Environment (build 1.8.0_312-b07)

OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)

2、查找已安装的jdk

rpm -qa | grep jdk
结果如下：

java-1.8.0-openjdk-1.8.0.312.b07-1.el7_9.x86_64

java-1.8.0-openjdk-devel-1.8.0.312.b07-1.el7_9.x86_64

copy-jdk-configs-3.3-10.el7_5.noarch

java-1.8.0-openjdk-headless-1.8.0.312.b07-1.el7_9.x86_64

3、卸载（.noarch可不删除）

rpm -e --nodeps java-1.8.0-openjdk-1.8.0.312.b07-1.el7_9.x86_64
rpm -e --nodeps java-1.8.0-openjdk-devel-1.8.0.312.b07-1.el7_9.x86_64
rpm -e --nodeps java-1.8.0-openjdk-headless-1.8.0.312.b07-1.el7_9.x86_64
