Linux配置Java/JDK（Kali启动JRMPListener报错）

中间件漏洞-Webloigc-CVE-2018-2628-T3协议反序列化漏洞
Shiro反序列化

>d 注意，这种方法会影响操作系统，也就是java命令全部都是用环境变量配置的这个版本。

如果需要切换版本，可以用这种方法安装，下面的就不用看了：
使用update-alternatives切换版本参考

# 错误原因
Java版本不匹配，ysoserial工具需要使用Java8启动

# 解决办法：Kali配置JDK8（Java8）

## 解压
建立目录，将下载的jdk的安装包复制过去并进行解压
```
mkdir -p /usr/local/java
cp jdk-8u181-linux-x64.tar.gz /usr/local/java
cd /usr/local/java
sudo tar xzvf jdk-8u181-linux-x64.tar.gz
```

## 配置环境变量
`vim /etc/profile`

添加以下内容（目录修改为你解压出来的目录）：
```
JAVA_HOME=/usr/local/java/jdk1.8.0_181
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export PATH
```

## 重新价值环境变量，使之生效
`source /etc/profile`

## 验证
`java -version`
