docker安装jdk

现需要新搭建一套Linux环境,现使用docker安装jdk;

环境:  Alibaba Cloud Linux 3

1.查看本地是否安装java

# java -version
-bash: java: command not found

2.使用docker拉取jdk镜像

# docker pull kdvolder/jdk8
Using default tag: latest
latest: Pulling from kdvolder/jdk8
50aff78429b1: Pull complete 
f6d82e297bce: Pull complete 
275abb2c8a6f: Pull complete 
9f15a39356d6: Pull complete 
fc0342a94c89: Pull complete 
8fa98a855564: Pull complete 
Digest: sha256:419d116314d545535b538fa0a3730836ab2505963e43412f25c70c3fd29bdff3
Status: Downloaded newer image for kdvolder/jdk8:latest
docker.io/kdvolder/jdk8:latest

3.查看镜像:

# docker images
REPOSITORY      TAG       IMAGE ID       CREATED       SIZE
kdvolder/jdk8   latest    b83ae7c076b1   5 years ago   488MB

4.运行镜像

# docker run -itd --name=jdk1.8 kdvolder/jdk8 bash
e93c8a419860cffb440e8fdfa1448f9775f80564d892f53da6ff3c063a59a828

5.查看镜像运行情况

# docker ps
CONTAINER ID   IMAGE           COMMAND   CREATED              STATUS              PORTS     NAMES
e93c8a419860   kdvolder/jdk8   "bash"    About a minute ago   Up About a minute             jdk1.8

 

Linux本地安装jdk:

1.创建文件夹

mkdir /usr/local/java/
cd /usr/local/java/

2.下载并解压

wget https://mirrors.tuna.tsinghua.edu.cn/Adoptium/8/jdk/x64/linux/OpenJDK8U-jdk_x64_linux_hotspot_8u392b08.tar.gz
ll
tar -zxvf OpenJDK8U-jdk_x64_linux_hotspot_8u392b08.tar.gz

3.设置环境变量

#  yum -y install nano

Complete!

 4.编辑环境变量文件

nano /etc/profile

将如下内容写入文件末尾

export JAVA_HOME=/usr/local/java/jdk8u392-b08
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

应用环境变量,使之生效

]# source /etc/profile

5.设置软连接

# ln -sf /usr/local/java/jdk8u392-b08/bin/java /usr/bin/java

6.查看jdk版本,是否安装成功

# java -version
openjdk version "1.8.0_392"
OpenJDK Runtime Environment (Temurin)(build 1.8.0_392-b08)
OpenJDK 64-Bit Server VM (Temurin)(build 25.392-b08, mixed mode)
