Huginn是一个神器,它是一个私人IFTTT,例如搭建任务采集触发平台,自动跟进实时提醒(用Email Slack Telegeram QQ 微信接受推送),全文 RSS 输出(把你关注的所有网页进行 RSS 全文输出),同时可以把各种app,软件,网络服务,网络设备等链接在一起做任务触发。
Huginn比起iFTTT,它更加强大,更加自动化,当然更加难以搞定。这是来自Huginn官网的一篇非常详细的关于Huginn手动安装教程,不要看这篇文章很长,但是老外写教程就是很认真,只要按照Huginn的官方教程成功在Debian/Ubuntu上安装Huginn的概率几乎就是100%。
网上也有一些Huginn安装的中文教程,但是Huginn的英文教程一直不断更新中,本篇文章就来记录一下Huginn手动在Debian/Ubuntu上安装的过程,参考的是Huginn最新的英文教程。由于英文原文非常长,所以只对关键地方作中文说明。

操作系统要求:
Supported Unix distributions by this guide
Ruby 版本
Huginn requires Ruby (MRI) 2.2 or 2.3. You will have to use the standard MRI implementation of Ruby. We love JRuby and Rubinius but Huginn needs several Gems that have native extensions.
Hardware requirements
CPU
内存
You need at least 0.5GB of physical and 0.5GB of addressable memory (swap) to install and use Huginn with the default configuration! With less memory you need to manually adjust the Gemfile
and Huginn can respond with internal server errors when accessing the web interface.
Unicorn Workers
For most instances we recommend using: CPU cores = unicorn workers.
If you have a 512MB machine we recommend to configure only one Unicorn worker and use the threaded background worker to prevent excessive swapping.
小结:Linux系统Debian/Ubuntu,内存最好是在1GB以上,CPU核心=unicorn workers,这个在后面的设置要用到。
The Huginn installation consists of setting up the following components:
sudo
is not installed on Debian by default. Make sure your system is up-to-date and install it.
# run as root!
apt-get update -y
apt-get upgrade -y
apt-get install sudo -y
Note: During this installation some files will need to be edited manually. If you are familiar with vim set it as default editor with the commands below. If you are not familiar with vim please skip this and keep using the default editor.
# Install vim and set as default editor
sudo apt-get install -y vim
sudo update-alternatives --set editor /usr/bin/vim.basic
Import node.js repository (can be skipped on Ubuntu and Debian Jessie):
curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -
Install the required packages (needed to compile Ruby and native extensions to Ruby gems):
sudo apt-get install -y runit build-essential git zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev curl openssh-server checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev logrotate python-docutils pkg-config cmake nodejs graphviz
Debian Stretch
Since Debian Stretch, runit
isn’t started anymore automatically, but this gets handled by the init system. Additionally, Ruby requires the OpenSSL 1.0 development packages instead of 1.1. For a default installation use these packages:
sudo apt-get install -y runit-systemd libssl1.0-dev
The use of Ruby version managers such as RVM, rbenv or chruby with Huginn in production frequently leads to hard-to-diagnose problems. Version managers are not supported and we strongly advise everyone to follow the instructions below to use a system Ruby.
Remove the old Ruby versions if present:
sudo apt-get remove -y ruby1.8 ruby1.9
Download Ruby and compile it:
mkdir /tmp/ruby && cd /tmp/ruby
curl -L --progress http://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.4.tar.bz2 | tar xj
cd ruby-2.3.4
./configure --disable-install-rdoc
make -j`nproc`
sudo make install
Install the bundler and foreman gems:
sudo gem install rake bundler foreman --no-ri --no-rdoc
Create a user for Huginn:
sudo adduser --disabled-login --gecos 'Huginn' huginn
Install the database packages
sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev
# Pick a MySQL root password (can be anything), type it and press enter,
# retype the MySQL root password and press enter
For Debian Stretch, replace libmysqlclient-dev
with default-libmysqlclient-dev
. See the additional notes section for more information.
Check the installed MySQL version (remember if its >= 5.5.3 for the .env
configuration done later):
mysql --version
Secure your installation
sudo mysql_secure_installation
Login to MySQL
mysql -u root -p
# Type the MySQL root password
Create a user for Huginn do not type the mysql>
, this is part of the prompt. Change $password
in the command below to a real password you pick
mysql> CREATE USER 'huginn'@'localhost' IDENTIFIED BY '$password';
Ensure you can use the InnoDB engine which is necessary to support long indexes
mysql> SET default_storage_engine=INNODB;
# If this fails, check your MySQL config files (e.g. `/etc/mysql/*.cnf`, `/etc/mysql/conf.d/*`)
# for the setting "innodb = off"
Grant the Huginn user necessary permissions on the database
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES ON `huginn_production`.* TO 'huginn'@'localhost';
Quit the database session
mysql> \q
Try connecting to the new database with the new user
sudo -u huginn -H mysql -u huginn -p -D huginn_production
# Type the password you replaced $password with earlier
You should now see ERROR 1049 (42000): Unknown database 'huginn_production'
which is fine because we will create the database later.
You are done installing the database and can go back to the rest of the installation.
Clone the Source
# We'll install Huginn into the home directory of the user "huginn"
cd /home/huginn
# Clone Huginn repository
sudo -u huginn -H git clone https://github.com/cantino/huginn.git -b master huginn
# Go to Huginn installation folder
cd /home/huginn/huginn
# Copy the example Huginn config
sudo -u huginn -H cp .env.example .env
# Create the log/, tmp/pids/ and tmp/sockets/ directories
sudo -u huginn mkdir -p log tmp/pids tmp/sockets
# Make sure Huginn can write to the log/ and tmp/ directories
sudo chown -R huginn log/ tmp/
sudo chmod -R u+rwX,go-w log/ tmp/
# Make sure permissions are set correctly
sudo chmod -R u+rwX,go-w log/
sudo chmod -R u+rwX tmp/
sudo -u huginn -H chmod o-rwx .env
# Copy the example Unicorn config
sudo -u huginn -H cp config/unicorn.rb.example config/unicorn.rb
Configure it
# Update Huginn config file and follow the instructions
sudo -u huginn -H editor .env
If you are using a local MySQL server the database configuration should look like this (use the password of the huginn MySQL user you created earlier):
DATABASE_ADAPTER=mysql2
DATABASE_RECONNECT=true
DATABASE_NAME=huginn_production
DATABASE_POOL=20
DATABASE_USERNAME=huginn
DATABASE_PASSWORD='$password'
#DATABASE_HOST=your-domain-here.com
#DATABASE_PORT=3306
#DATABASE_SOCKET=/tmp/mysql.sock
DATABASE_ENCODING=utf8
# MySQL only: If you are running a MySQL server >=5.5.3, you should
# set DATABASE_ENCODING to utf8mb4 instead of utf8 so that the
# database can hold 4-byte UTF-8 characters like emoji.
#DATABASE_ENCODING=utf8mb4
Important: Uncomment the RAILS_ENV setting to run Huginn in the production rails environment
RAILS_ENV=production
Change the Unicorn config if needed, the requirements.md has a section explaining the suggested amount of unicorn workers:
# Increase the amount of workers if you expect to have a high load instance.
# 2 are enough for most use cases, if the server has less then 2GB of RAM
# decrease the worker amount to 1
sudo -u huginn -H editor config/unicorn.rb
Important Note: Make sure to edit both .env
and unicorn.rb
to match your setup.
Note: If you want to use HTTPS, which is what we recommend, see Using HTTPS for the additional steps.
Note: For configuration changes after finishing the initial installation you have to re-export (see Install Init Script) the init script every time you change .env
, unicorn.rb
or your Procfile
!
Install Gems
Note: As of bundler 1.5.2, you can invoke bundle install -jN
(where N
the number of your processor cores) and enjoy parallel gem installation with measurable difference in completion time (~60% faster). Check the number of your cores with nproc
. For more information check this post. First make sure you have bundler >= 1.5.2 (run bundle -v
) as it addresses some issues that were fixed in 1.5.2.
sudo -u huginn -H bundle install --deployment --without development test
Initialize Database
# Create the database
sudo -u huginn -H bundle exec rake db:create RAILS_ENV=production
# Migrate to the latest version
sudo -u huginn -H bundle exec rake db:migrate RAILS_ENV=production
# Create admin user and example agents using the default admin/password login
sudo -u huginn -H bundle exec rake db:seed RAILS_ENV=production SEED_USERNAME=admin SEED_PASSWORD=password
When done you see See the Huginn Wiki for more Agent examples! https://github.com/cantino/huginn/wiki
Note: This will create an initial user, you can change the username and password by supplying it in environmental variables SEED_USERNAME
and SEED_PASSWORD
as seen above. If you don’t change the password (and it is set to the default one) please wait with exposing Huginn to the public internet until the installation is done and you’ve logged into the server and changed your password.
Compile Assets
sudo -u huginn -H bundle exec rake assets:precompile RAILS_ENV=production
Install Init Script
Huginn uses foreman to generate the init scripts based on a Procfile
Edit the Procfile
and choose one of the suggested versions for production
sudo -u huginn -H editor Procfile
Comment out (disable) these two lines
web: bundle exec rails server -p ${PORT-3000} -b ${IP-0.0.0.0}
jobs: bundle exec rails runner bin/threaded.rb
Enable (remove the comment) from these lines or those
# web: bundle exec unicorn -c config/unicorn.rb
# jobs: bundle exec rails runner bin/threaded.rb
Export the init scripts:
sudo bundle exec rake production:export
Note: You have to re-export the init script every time you change the configuration in .env
or your Procfile
!
Setup Logrotate
sudo cp deployment/logrotate/huginn /etc/logrotate.d/huginn
Ensure Your Huginn Instance Is Running
sudo bundle exec rake production:status
Note: Nginx is the officially supported web server for Huginn. If you cannot or do not want to use Nginx as your web server, the wiki has a page on how to configure apache.
Installation
sudo apt-get install -y nginx
Site Configuration
Copy the example site config:
sudo cp deployment/nginx/huginn /etc/nginx/sites-available/huginn
sudo ln -s /etc/nginx/sites-available/huginn /etc/nginx/sites-enabled/huginn
Make sure to edit the config file to match your setup, if you are running multiple nginx sites remove the default_server
argument from the listen
directives:
# Change YOUR_SERVER_FQDN to the fully-qualified
# domain name of your host serving Huginn.
sudo editor /etc/nginx/sites-available/huginn
Remove the default nginx site, if huginn is the only enabled nginx site:
sudo rm /etc/nginx/sites-enabled/default
Note: If you want to use HTTPS, which is what we recommend, replace the huginn
Nginx config with huginn-ssl
. See Using HTTPS for HTTPS configuration details.
Test Configuration
Validate your huginn
or huginn-ssl
Nginx config file with the following command:
sudo nginx -t
You should receive syntax is okay
and test is successful
messages. If you receive errors check your huginn
or huginn-ssl
Nginx config file for typos, etc. as indicated in the error message given.
Restart
sudo service nginx restart
Done!
Initial Login
Visit YOUR_SERVER in your web browser for your first Huginn login. The setup has created a default admin account for you. You can use it to log in:
admin (or your SEED_USERNAME)
password (or your SEED_PASSWORD)
Enjoy!
You can use cd /home/huginn/huginn && sudo bundle exec rake production:start
and cd /home/huginn/huginn && sudo bundle exec rake production:stop
to start and stop Huginn.
Be sure to read the section about how to update your Huginn installation as well! You can also use Capistrano to keep your installation up to date.
Note: We also recommend applying standard security practices to your server, including installing a firewall (ufw is good on Ubuntu and also available for Debian).
Using HTTPS
To use Huginn with HTTPS:
.env
: FORCE_SSL
option to true
.huginn-ssl
Nginx example config instead of the huginn
config: sudo cp deployment/nginx/huginn-ssl /etc/nginx/sites-available/huginn
YOUR_SERVER_FQDN
. ssl_certificate
and ssl_certificate_key
. Restart Nginx, export the init script and restart Huginn:
cd /home/huginn/huginn
sudo service nginx restart
sudo bundle exec rake production:export
Using a self-signed certificate is discouraged, but if you must use it follow the normal directions. Then generate the certificate:
sudo mkdir -p /etc/nginx/ssl/
cd /etc/nginx/ssl/
sudo openssl req -newkey rsa:2048 -x509 -nodes -days 3560 -out huginn.crt -keyout huginn.key
sudo chmod o-r huginn.key
If something went wrong during the installation please make sure you followed the instructions and did not miss a step.
When your Huginn instance still is not working first run the self check:
cd /home/huginn/huginn
sudo bundle exec rake production:check
We are sorry when you are still having issues, now please check the various log files for error messages:
Nginx error log /var/log/nginx/huginn_error.log
This file should be empty, it is the first place to look because nginx
is the first application handling the request your are sending to Huginn.
常见的问题:
connect() to unix:/home/huginn/huginn/tmp/sockets/unicorn.socket failed
: The Unicorn application server is not running, ensure you uncommented one of the example configuration below the PRODUCTION
label in your Profile and the unicorn config file (/home/huginn/huginn/config/unicorn.rb
) exists. 138 open() "/home/huginn/huginn/public/..." failed (13: Permission denied)
: The /home/huginn/huginn/public
directory needs to be readable by the nginx user (which is per default www-data
)Unicorn log /home/huginn/huginn/log/unicorn.log
Should only contain HTTP request log entries like: 10.0.2.2 - - [18/Aug/2015:21:15:12 +0000] "GET / HTTP/1.0" 200 - 0.0110
If you see ruby exception backtraces or other error messages the problem could be one of the following:
/home/huginn/huginn/config/unicorn.rb
does not exist Rails Application log /home/huginn/huginn/log/production.log
This file is pretty verbose, you want to look at it if you are getting the We're sorry, but something went wrong.
error message when using Huginn. This is an example backtrace that can help you or other huginn developers locate the issue:
NoMethodError (undefined method `name' for nil:NilClass):
app/controllers/jobs_controller.rb:6:in `index'
config/initializers/silence_worker_status_logger.rb:5:in `call_with_silence_worker_status'
Runit/Background Worker logs /home/huginn/huginn/log/*/current
Those files will contain error messages or backtraces if one of your agent is not performing as they should. The easiest way to debug an Agent is to watch all your log files for changes and trigger the agent to run via the Huginn web interface.
The log file location depends your Procfile
configuration, this command will give you a list of the available logs:
ls -al /home/huginn/huginn/log/*/current
When you want to monitor the background processes you can easily watch all the files for changes:
tail -f /home/huginn/huginn/log/*/current
我遇到的问题:unicorn workers设置导致Huginn502错误。上面已经说过CPU cores = unicorn workers,所以我们在执行:sudo -u huginn -H editor config/unicorn.rb
时一定要根据自己的VPS的CPU来修改对应的数值。
打开你的域名或者IP地址,你就可以访问到Huginn登录页面了,如果你按照上面的方法操作的话,登录账号是:admin,密码是:password,你可以进入到Huginn修改。
这就是Huginn的操作界面了,对应的就是Agents、Scenarios、Events、Credentials、Services。(点击放大)
Agents就是你的派出去搜索情报的“小兵”了。
Events会记录“小兵”出去回来都带了什么东西。
scenarios是“小兵”组团称呼,一个团可以放好多协作的“小兵”。
scenarios方便之处就在于你可以直接导入别人已经写好的脚本,自己只要修改对应的参数就可以直接上线运行了。这里有一个公共脚本库:http://huginnio.herokuapp.com/scenarios,常用的知乎话题监控、

配置mysql本地服务器,vps需要吗
需要弄吗
而且还发现一个问题,bundle和ruby的资源占用率好高啊,vps的cpu占用率一直是100%。
站长,我按照教程安装huginn最后也出现了 bad gateway 502 错误。
我在config/unicorn.rb这个文件里也没找到有关unicorn的语句,只找到这句
worker_processes Integer(ENV["WEB_CONCURRENCY"] || 2)
默认是2,我的vps cpu只有单核,于是我改成1,最后运行502,然后又找到这里修改为2,执行初始化脚本
sudo bundle exec rake production:export
后,还是502错误。
请问我是哪里没做对么?
看错误提示,应该是配置这一块还没有填写正确。
在第二部分 第5节,执行 sudo -u huginn -H editor .env 之后,误清空了内容并保存了。应该如何回复呢?
您好,我有一个想问一下您,配置完毕以后,我在浏览器输入IP地址,但是显示502 Bad Gateway,是不是需要端口进行访问?
不需要端口,如果出现这样的情况可能是安装失败了。
您好,在To use Huginn with HTTPS的时候,第二步用huginn-ssl取代huginn中,Update ssl_certificate and ssl_certificate_key,是什么意思,具体应该怎么操作呢?感谢🙏
你好,
sudo apt-get install -y runit-systemd libssl1.0-dev
出现unable to locate package
怎么解决?
先执行:
sudo apt-get update
,然后就可以了。你好,执行了sudo apt-get update,还是会提示
E: Unable to locate package runit-systemd
E: Unable to locate package libssl1.0-dev
,使用的是VPS主机,系统是UBUNTU16.04,谢谢啦
谢谢老大!!昨晚部署成功,今天研究了一早上终于可以烧录rss了。。。爽爽
可以研究一下它的规则,能实现更强的抓取信息的需要。
初始化数据库提示rake-12.0.0不存在公开源怎么办
那可能还需要手动安装最新版的rake
按照步骤操作,安装的rake版本高于12.0.0,不能用,我能否把vps账号给你 你帮我试试
我的也是这样的情况,无数次重试,没有效果
以前记得有个和IFFIT差不多的网站的,好久没用忘记了。
看起来你推荐的这个很强大啊。不过一般的微信通知我用那个SERVER酱就很方便了
是的,IFFIT还是适合专业人士使用,普通用户可能只需要一个APP就可以了。
