2. 安装hubot

[root@node1 ~]# npm install -g hubot coffee-script yo generator-hubot
[root@node1 ~]# mkdir myhubot && cd myhubot
[root@node1 myhubot]# yo hubot  (提示没有权限)
/usr/local/nodejs/lib/node_modules/yo/node_modules/mkdirp/index.js:90
                    throw err0;
                    ^

Error: EACCES: permission denied, mkdir '/root/.config'
    at Error (native)

[root@node1 myhubot]# chmod g-w /root　（将root目录权限恢复原状）
[root@node1 myhubot]# npm install hubot-bearychat --save
myhubot@0.0.0 /root/myhubot

安装shell 命令脚本支持模块：

[root@node1 myhubot]# npm install hubot-script-shellcmd
myhubot@0.0.0 /root/myhubot
└── hubot-script-shellcmd@0.0.16
[root@node1 myhubot]# cp -R node_modules/hubot-script-shellcmd/bash ./

修改一下external-scripts.json，添加模块：hubot-script-shellcmd
[root@node1 myhubot]# cat external-scripts.json 
[
  "hubot-diagnostics",
  "hubot-help",
  "hubot-heroku-keepalive",
  "hubot-google-images",
  "hubot-google-translate",
  "hubot-pugme",
  "hubot-maps",
  "hubot-redis-brain",
  "hubot-rules",
  "hubot-shipit",
  "hubot-script-shellcmd"  //新增部分
]
[root@node1 myhubot]# cd bash/handlers/
[root@node1 handlers]# ls
helloworld  update

新增脚本
[root@node1 handlers]# cat disk 
#!/bin/bash
df -h
[root@node1 handlers]# chmod +x disk 

3. 注册bearychat添加机器人

• https://www.bearychat.com 注册并登陆
  
  
  

注意：

• 复制Hubot Token 这个很重要
• Hubot URL 端口可以随意指定【export EXPRESS_PORT=9090】

下载bearychat客户端或者直接使用网页版都可以

配置hubot并启动

此处的token就是第三步添加机器人时显示的token多个使用逗号分隔
[root@node1 myhubot]# export HUBOT_BEARYCHAT_TOKENS=bd00e55956a3759886c21c1ac1fd17dd
[root@node1 myhubot]# export HUBOT_BEARYCHAT_MODE=rtm
[root@node1 myhubot]# export EXPRESS_PORT=9090
[root@node1 myhubot]# nohup ./bin/hubot -a bearychat 2&1> hubot.log
[root@node1 myhubot]# netstat -tnlp|grep 9090
tcp        0      0 0.0.0.0:9090            0.0.0.0:*               LISTEN      54886/node 

为了以后启动方便可以直接将变量写人文件：
[root@node1 myhubot]# cat /etc/profile.d/myhubot.sh 
export HUBOT_BEARYCHAT_TOKENS=bd00e5595121249886c21c1ac1fd17dd
export HUBOT_BEARYCHAT_MODE=rtm
export EXPRESS_PORT=9090
[root@node1 myhubot]# source /etc/profile 
这样以后就无需手动再次export

5. 客户端登录并测试

6. 机器人脚本示例

[root@node1 ~]# cd myhubot/scripts
[root@node1 scripts]# vim example.coffee   (编辑并修改) 
....
#   Uncomment the ones you want to try and experiment with.
#
#   These are from the scripting documentation: https://github.com/github/hubot/blob/master/docs/scripting.md

module.exports = (robot) ->

   robot.hear /jevic/i, (res) ->
     res.send "https://jevic.github.io"

#   robot.respond /open the (.*) doors/i, (res) ->
....

• 重启hubot
  [root@node1 ~]# nohup ./bin/hubot -a bearychat 2&1>> hubot.log &
