+# 机器学习检测Webshell
+
+# 简介
+
+提取PHP执行中的opcode，采用 opcode词袋 + tf-idf 进行关键信息提取
+
+采用朴素贝叶斯算法进行训练。
+
+进行 PHP WebShell 的检测。
+
+# 部署
+
+## step 1. Python环境部署
+
+```
+pip install -r requirements.txt
+```
+
+## step 2. PHP opcode 部署
+
+    开启opcode模式
+
+windows环境
+
+```
+1. 下载 vld.dll 插件并存放在php ext 目录下
+2. 配置 php.ini 激活vld.dll 文件
+```
+[VLD.dll下载地址](http://pecl.php.net/package/vld/0.14.0/windows)
+
+[PHP.ini 配置参考文章](http://blog.sina.com.cn/s/blog_4c8c58ce0102wi2h.html
+)
+
+# 第一次进行训练
+
+    将白名单的文件放入到 white-list 文件夹中
+    将黑名单文件放入到 black-list 文件夹中
+
+进行第一次训练
+```shell
+python train.py
+```
+Note:
+
+    避免每次生成opcode 的时间过长，每次训练完成后，会生成两个文件，black_opcodes.txt & white_opcodes.txt。
+
+    如果有新的白名单文件或者黑名单文件加入，先删除掉black_opcodes.txt 和 white_opcodes.txt 文件，然后再次进行训练。
+
+    训练完成后，会在save文件夹内，生成一个gnb.pkl文件，这个是训练好的缓存文件。
+
+
+# 检测
+
+检测单个文件
+```
+python check.py [filename]
+```
+
+
+# 重复训练
+
+1. 提供训练集
+在人工得到结果后，可以在white-list & black-list 文件夹中，添加已知的结果，再按照第一次训练的方法，进行再次训练。得到的结果便会更加准确。
