+# 部署补充
+- 若内网部署，draw.io无法使用外网，则需要用tomcat运行war包，见（https://github.com/jgraph/drawio） 从release下载，之后修改markdown.js的TODO行对应的链接即可
+- 为了护眼，简单增加了编辑界面的主题切换，见editormd.js和markdown_edit_template.tpl
+- (需重新编译项)为了对已删除文档/文档引用图片删除文字后，对悬空无引用的图片/附件进行清理，增加了清理接口，需重新编译
+     - 编译后除二进制文件外还需更新三个文件: conf/lang/en-us.ini,zh-cn.ini; attach_list.tpl
+     - 若不想重新编译，也可通过database/clean.py，手动执行对无引用图片/附件的文件清理和数据库记录双向清理。
+- 若采用nginx二级部署，以yourpath/为例，需修改
+     - conf/app.conf修改：`baseurl="/yourpath"`
+     - static/js/kancloud.js文件中`url: "/comment/xxxxx` => `url: "/yourpath" + "/comment/xxxxx`, 共两处
+
+     - nginx端口代理示例:
+     ```
+     增加
+     location  /yourpath/ {
+          rewrite ^/yourpath/(.*) /$1  break;
+          proxy_pass http://127.0.0.1:8181;
+     }
+     ```
+     注意使用的是127.0.0.1，根据自身选择替换，如果nginx是docker部署，则还需要在docker中托管运行mindoc，具体参考如下配置:
+     - docker-compose代理示例(docker-nginx代理运行mindoc)
+     ```
+     version: '3'
+     services:
+       mynginx:
+       image: nginx:latest
+       ports:
+         - "8880:80"
+       command: 
+         - bash
+         - -c
+         - |
+             service nginx start
+             cd /src/mindoc/ && ./mindoc
+       volumes:
+         - ..:/src
+         - ./nginx:/etc/nginx/conf.d
+     ```
+
+     目录结构
+     ```
+     onefolder
+     |
+       - docker
+       |
+         - docker-compose.yml
+         - nginx
+         |
+           - mynginx.conf

+         - conf/
