1.4 启动hubot

2、安装rocketchat

2.1 安装mongodb

vim /etc/yum.repos.d/mongodb-org.repo

yum -y install mongodb-org
systemctl start mongod
systemctl enable mongod

2.2 安装rocketchat

cd /opt
curl -L https://rocket.chat/releases/latest/download -o rocket.chat.tgz tar zxvf rocket.chat.tgz mv bundle Rocket.Chat 
cd Rocket.Chat/programs/server
npm install

2.3 启动rocketchat

cd /opt/Rocket.Chat
export ROOT_URL=http://xxx.rocket.com/
export MONGO_URL=mongodb://localhost:27017/rocketchat
export PORT=3000 
node main.js

        error_log   /var/log/nginx/rocket.com_error.log;
       }

    location / {
        proxy_pass http://rocketchat_backend/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $http_host;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forward-Proto http;
        proxy_set_header X-Nginx-Proxy true;

        proxy_redirect off;
    }
}

2.5 浏览器输入xxx:3000

3、安装hubot-rocketchat adapter

3.1 启动一个docket镜像

docker run -it -e ROCKETCHAT_URL="http://IP:3000" \
-e ROCKETCHAT_ROOM='' \
-e LISTEN_ON_ALL_PUBLIC=true \
-e ROCKETCHAT_USER=admin \
-e ROCKETCHAT_PASSWORD=123456 \
-e ROCKETCHAT_AUTH=password \
-e BOT_NAME=bot \
-e EXTERNAL_SCRIPTS=hubot-pugme,hubot-help \
rocketchat/hubot-rocketchat

3.2 启动时，指定环境变量，使得Hubot等登录上rocketchat(注意：在启动hubot之前，先刷环境变量)

export ROCKETCHAT_URL="http://IP:3000" 
export ROCKETCHAT_ROOM='' 
export LISTEN_ON_ALL_PUBLIC=true
export ROCKETCHAT_USER=admin 
export ROCKETCHAT_PASSWORD=123456 
export ROCKETCHAT_AUTH=password

3.3 验证

编辑myhubot/scripts目录下的example.coffee文件，添加如下行：

robot.hear /hi/i, (res) ->
     res.reply "hello"
robot.hear /吃饭了吗/, (res) ->
     res.send '只有你们这些愚蠢的人类才吃饭'

在rocketcha里面对话如下，测试ok

3.4 hubot 运行bash脚本，安装插件：hubot-script-shellcmd

cd myhubot
npm install hubot-script-shellcmd
cp -R node_modules/hubot-script-shellcmd/bash .   #seperate your shellcmd from the npm module

编辑 external-scripts.json
add 'hubot-script-shellcmd' 

上述操作完成后，我们可以看到，在myhubot目录下有个bash目录，cd bash/handlers,该目录下有两个文件：helloworld，update，在rocketchat中，可以直接执行@admin shellcmd 以及@admin shellcmd helloworld执行上面的命令.
