在 Linux 上搭建 Hubot 聊天机器人服务器

在 Linux 上搭建 Hubot 聊天机器人服务器

1. 先确定安装了 Node.js
如果还没安装Node.js，就先安装Node.js。Node.js是绿色软件，只要解压安装包即可。这里假设已经在/data/node-v5.12.0/目录下安装了 node-v5.12.0 。

2. 安装 Hubot 框架
# npm install -g yo generator-hubot

3. 创建 Hubot 项目
# mkdir myHubot
# cd myHubot
# yo hubot

如果出现错误：
/usr/bin/node: No such file or directory

软连接解决：
# ln -s /data/node-v5.12.0/bin/node /usr/bin/node
# ln -s /data/node-v5.12.0/bin/npm /usr/bin/npm

再试：
# yo hubot
/data/node-v5.12.0/lib/node_modules/yo/node_modules/mkdirp/index.js:90
                    throw err0;
                    ^
Error: EACCES: permission denied, mkdir '/root/.config'
    at Error (native)
    at Object.fs.mkdirSync (fs.js:842:18)
    at sync (/data/node-v5.12.0/lib/node_modules/yo/node_modules/mkdirp/index.js:71:13)
    at Function.sync (/data/node-v5.12.0/lib/node_modules/yo/node_modules/mkdirp/index.js:77:24)
    at Object.create.all.get (/data/node-v5.12.0/lib/node_modules/yo/node_modules/configstore/index.js:38:13)
    at Object.Configstore (/data/node-v5.12.0/lib/node_modules/yo/node_modules/configstore/index.js:27:44)
    at new Insight (/data/node-v5.12.0/lib/node_modules/yo/node_modules/insight/lib/index.js:37:34)
    at Object.<anonymous> (/data/node-v5.12.0/lib/node_modules/yo/lib/cli.js:172:11)
    at Module._compile (module.js:413:34)
    at Object.Module._extensions..js (module.js:422:10)

如果出现上面错误，就执行：
# chmod g+rwx /root

然后再试：
# yo hubot

出现了上面安装提示界面，输入所有者、Hubot 名称和描述等。输好后会根据输入的创建对应的配置文件，然后进行处理，并且安装一些模块文件等。
等待安装完成就可以使用了，执行下面命令。

# ./bin/hubot

上面提示 8080 端口被占用了，可以指定端口执行，比如换 8100 端口：
# PORT=8100 ./bin/hubot

出现上面显示，说明机器人正常启动。

4. 验证 Hubot 是否安装完成
在命令行里输入 myHubot ping ，如果能看到回复 PONG，说明 Hubot 就安装完成了。
如下：
myhubot> myHubot ping
myhubot> PONG

注：myHubot ping 中的 myHubot 是你的机器人名称。

5. 查看可以使用哪些命令
想查看可以使用哪些命令，在命令行里输入 myHubot help 。
如下：
myhubot> myHubot help
myhubot> Shell: myhubot adapter - Reply with the adapter
myhubot animate me <query> - The same thing as `image me`, except adds a few parameters to try to return an animated GIF instead.
