运行容器

$ docker run -d -p 8001:8001 -p 8081:8081 -p 8082:8082 --name=local_centos --privileged=true -it centos /usr/sbin/init
$ docker exec -it local_centos /bin/bash

解决Centos8中yum命令遇到的问题

在/etc/yum.repos.d中更新一下源，使用vault.centos.org代替mirror.centos.org

$ sed -i -e "s|mirrorlist=|#mirrorlist=|g" /etc/yum.repos.d/CentOS-*
$ sed -i -e "s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g" /etc/yum.repos.d/CentOS-*

打包项目

拷贝.jar到容器中

$ docker cp ./eureka-server-0.0.1-SNAPSHOT.jar local_centos:/home/server/
$ docker cp ./service-01-0.0.1-SNAPSHOT.jar local_centos:/home/server/
$ docker cp ./service-02-0.0.1-SNAPSHOT.jar local_centos:/home/server/

安装jdk

$ yum search java-1.8.0-openjdk
$ yum install java-1.8.0-openjdk.x86_64 -y
$ java -version

后台运行.jar

$ java -jar /home/server/eureka-server-0.0.1-SNAPSHOT.jar &
$ java -jar /home/server/service-01-0.0.1-SNAPSHOT.jar &
$ java -jar /home/server/service-02-0.0.1-SNAPSHOT.jar &

后台运行.jar并输入日志

$ nohup java -jar /home/server/eureka-server-0.0.1-SNAPSHOT.jar > logs/debug8001.log 2>&1 &
$ nohup java -jar /home/server/service-01-0.0.1-SNAPSHOT.jar > logs/debug8081.log 2>&1 &
$ nohup java -jar /home/server/service-02-0.0.1-SNAPSHOT.jar > logs/debug8082.log 2>&1 &

实时查看日志

$ tail -100f logs/debug.log

查看/杀死运行程序

$ ps -ef|grep java
$ ps -aux|grep java # aux显示所有状态
$ kill -9 PID
