hj_服务器操作记录03_jdk11安装,podman运行springboot--jar包程序

主机环境安装jdk11;

官网下载:   https://www.oracle.com/java/technologies/downloads/#java11

本机是centos8 64位系统的.选择的是x64 Compressed Archive jdk-11.0.13_linux-x64_bin.tar.gz ;

上传此安装包到 /home下解压暂放. tar  zxf  jdk-11.0.13_linux-x64_bin.tar.gz 得到 jdk-11.0.13 文件目录;

拷贝此目录到 usr/local/jdk 下.  mkdir /usr/local/jdk  ;  cp  -r  /home/jdk-11.0.13  /usr/local/jdk ;

设置环境变量,配置 /etc/profile 文件, 文件尾部添加:

# JAVA11_HOME
export JAVA11_HOME=/usr/local/jdk/jdk-11.0.13
export CLASSPATH=$JAVA11_HOME/lib
export PATH=$JAVA11_HOME/bin:$PATH

刷新此配置文件: source /etc/profile ;

检查是否安装成功: java   javac  java -version 

宿主机安装jdk11  over.

 

创建Dockerfile 上传springboot-jar包,运行...

[root@iZc3hwg7f2i7mfZ jdk]# cd /home/
[root@iZc3hwg7f2i7mfZ home]# mkdir hj_docker_01
[root@iZc3hwg7f2i7mfZ home]# cd hj_docker_01/
[root@iZc3hwg7f2i7mfZ hj_docker_01]# touch Dockerfile
[root@iZc3hwg7f2i7mfZ hj_docker_01]# ls
Dockerfile  hj1208-0.0.1-SNAPSHOT.jar

不使用宿主机jdk,拉取openjdk11的镜像挂载jar包..直接run 

podman run -d --privileged=true  --name hj1208  \
 -p 8888:8888 \
  -v /home/hj_docker_01/hj1208-0.0.1-SNAPSHOT.jar:/opt/hj/spring/hj1208-0.0.1-SNAPSHOT.jar \
  docker.io/openjdk:11 \
 java -jar /opt/hj/spring/hj1208-0.0.1-SNAPSHOT.jar

配置 Dockerfile运行..还是得使用那个openjdk11...宿主机的jdk白装啦,不会用

怎么使用宿主机的jdk 有待进一步研究...
