安装步骤

jdk

复制代码

dh@d:~$ java -version
Command 'java' not found, but can be installed with:
sudo apt install openjdk-11-jre-headless  # version 11.0.20.1+1-0ubuntu1~22.04, or
sudo apt install default-jre              # version 2:1.11-72build2
sudo apt install openjdk-17-jre-headless  # version 17.0.8.1+1~us1-0ubuntu1~22.04
sudo apt install openjdk-18-jre-headless  # version 18.0.2+9-2~22.04
sudo apt install openjdk-19-jre-headless  # version 19.0.2+7-0ubuntu3~22.04
sudo apt install openjdk-8-jre-headless   # version 8u382-ga-1~22.04.1

安装一下

复制代码

sudo apt install openjdk-8-jre-headless

$ java -version
openjdk version "1.8.0_392"
OpenJDK Runtime Environment (build 1.8.0_392-8u392-ga-1~22.04-b08)
OpenJDK 64-Bit Server VM (build 25.392-b08, mixed mode)

配置 JAVA_HOME

复制代码

update-alternatives --list java

如下：

复制代码

/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java

则对应的 java home 为：/usr/lib/jvm/java-8-openjdk-amd64/jre

我们修改一下 /etc/profile

复制代码

sudo vi /etc/profile

添加对应的 java_home 信息：

bash 复制代码

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
export PATH=$JAVA_HOME/bin:$PATH

刷新配置：

复制代码

source /etc/profile

测试：

复制代码

$ echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64/jre

验证

复制代码

$ java -version
openjdk version "1.8.0_402"
OpenJDK Runtime Environment (build 1.8.0_402-8u402-ga-2ubuntu1~22.04-b06)
OpenJDK 64-Bit Server VM (build 25.402-b06, mixed mode)
