Debian 10 更换163源并安装Java 8和maven记录

新安装的Debian 10，需要对安装源镜像地址进行修改

因为在国内，个人使用感觉163的源最快，最稳定。。。

备份系统的安装源地址，方便有需要时候恢复使用

mv /etc/apt/sources.list /etc/apt/sources.list_back_20200401

创建新的163源地址

vi /etc/apt/sources.list

添加下面地址

  deb http://mirrors.163.com/debian/ stretch main non-free contrib
    deb http://mirrors.163.com/debian/ stretch-updates main non-free contrib
    deb http://mirrors.163.com/debian/ stretch-backports main non-free contrib
    deb-src http://mirrors.163.com/debian/ stretch main non-free contrib
    deb-src http://mirrors.163.com/debian/ stretch-updates main non-free contrib
    deb-src http://mirrors.163.com/debian/ stretch-backports main non-free contrib
    deb http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib
    deb-src http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib

apt-get update && apt-get upgrade

更新系统镜像。。。

安装Java和maven

apt-get install openjdk-8-jdk
apt-get install maven
mvn -version //查看maven版本
java -v  //查看Java的版本
