Centos7安装jdk8并制作box镜像

一、centos7安装jdk

1、下载jdk安装文件

https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

2、解压jdk到安装目录

$ mkdir  /usr/java
$ touch /vagrant/jdk-install.log 
$ tar -zxvf  /vagrant/jdk-8u181-linux-x64.tar.gz  -C /usr/java  >> /vagrant/jdk-install.log 
$ tail -n 10 /vagrant/jdk-install.log 
$ ls -l /usr/java

tar-jdk

3、设置环境变量到/etc/profile

$ JAVA_HOME=/usr/java/jdk1.8.0_181
$ JAVA_BIN=/usr/java/jdk1.8.0_181/bin

$ echo "export JAVA_HOME="$JAVA_HOME >>/etc/profile
$ echo "export JAVA_BIN="$JAVA_BIN >>/etc/profile
$ echo "export PATH=\$PATH:\$JAVA_BIN" >>/etc/profile
$ echo "export CLASSPATH=.:"\$JAVA_HOME/lib:\$JAVA_HOME/jre/lib >>/etc/profile

$ tail -n 10 /etc/profile

set-etc-profile

4、验证安装

$ source /etc/profile
$ java -version

java-version

二、通过vagrant一键式安装

将一中的脚本执行过程制作成脚本，在vagrantfile中直接引用执行脚本，一键安装
shell脚本jdk-install.sh如下：

echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>>jdk压缩包路径>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
echo $JDK_FILE
echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>jdk安装路径>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
echo $JDK_INSTALL_PATH

echo ">>>>>>>>>>>>>>>>>>>创建目录并解压jdk压缩包到安装路径>>>>>>>>>>>>>>>>>>"
echo $JDK_INSTALL_DIR
mkdir $JDK_INSTALL_DIR
touch $JDK_INSTALL_DIR/jdk-install.log 
tar -zxvf $JDK_FILE -C $JDK_INSTALL_DIR  >> $JDK_INSTALL_DIR/jdk-install.log 
tail -n 10 $JDK_INSTALL_DIR/jdk-install.log 
 ls -l  $JDK_INSTALL_DIR

echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>设置环境变量>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
JAVA_HOME=$JDK_INSTALL_PATH
JAVA_BIN=$JDK_INSTALL_PATH/bin
echo $JAVA_HOME
echo $JAVA_BIN

echo ">>>>>>>>>>>>>>>>>>>>>>>设置环境变量到/etc/profile>>>>>>>>>>>>>>>>>>>>>>"
echo "export JAVA_HOME="$JAVA_HOME >>/etc/profile
echo "export JAVA_BIN="$JAVA_BIN >>/etc/profile
echo "export PATH=\$PATH:\$JAVA_BIN" >>/etc/profile
echo "export CLASSPATH=.:"\$JAVA_HOME/lib:\$JAVA_HOME/jre/lib >>/etc/profile

tail -n 10 /etc/profile

echo ">>>>>>>>>>>>>>>>>>>>>>>>>>source一下让设置生效>>>>>>>>>>>>>>>>>>>>>>>>>"
source /etc/profile
echo ">>>>>>>>>>>>>>>>>>>>>>>>>>看下java命令是否可用>>>>>>>>>>>>>>>>>>>>>>>>>>"
java -version
javac -version 
echo ">>>默认的公钥在启动的时候会被移除,作为base的box,用默认公钥方便ssh登录>>>"
curl https://raw.githubusercontent.com/mitchellh/vagrant/master/keys/vagrant.pub >> /home/vagrant/.ssh/authorized_keys

Vagrantfile内容如下：

# -*- mode: ruby -*-
# vi: set ft=ruby :
    
Vagrant.configure("2") do |config|
    #设置虚拟机的box
    config.vm.box = "centos7-base"
    
    #设置虚拟机的主机名
    config.vm.hostname = "centos7-base-jdk"
    
    #Virtualbox相关配置
    config.vm.provider "virtualbox" do |v|
        #设置虚拟机的名称
        v.name = "centos7-base-jdk"
        
        #设置虚拟机的内存大小为2G
        v.memory = 2048 
        
        #设置虚拟机的CPU个数
        v.cpus = 2 
    end 
    
    #使用shell脚本进行软件安装和配置
    config.vm.provision "shell" do |s| 
        s.path = "jdk-install.sh"
        s.env = {JDK_FILE: "/vagrant/jdk-8u181-linux-x64.tar.gz", 
            JDK_INSTALL_DIR: "/usr/java",
            JDK_INSTALL_PATH: "/usr/java/jdk1.8.0_181"}
    end     
end

vagrant up拉起虚拟机，自动安装jdk， 安装结果：

java-version

三、打包centos7-base-jdk成box，并加入到box list

创建一个目录，然后打开命令行，打包虚拟机成box，–base的参数必须是安装的centos7的虚拟机名称，本次是centos7-base-jdk。
再将生成的box添加到box list中，后续就可以直接使用centos7-base-jdk8作为镜像创建虚拟机了。

$ vagrant package --output centos7-base-jdk8.box --base centos7-base-jdk
$ vagrant box add centos7-base-jdk8 centos7-base-jdk8.box
$ vagrant box list
