Huginn 环境搭建

什么是 Huginn ？

Huginn 是一个可以通过构建 agents 来帮你实现在线自动化任务的系统。它们可以理解 web，监听事件，按你所需地去执行一些行为。Huginn 的 agents 创建和消费事件，通过有向图表来进行转播。你可以把它当作部署在你自己的服务器上的破解版本的 IFTTT 或 Zapier。

你可以用 Huginn 做什么？

追踪天气并在明天下雨（雪）的时候邮件通知给你（明天不要忘记带伞）。
列出你关心的条目，并在 Twitter 发生改变的时候电子邮件通知给你。（例如，想知道在机器学习领域发生了什么有趣的事情吗？Huginn 将在 Twitter 上观察“machine learning”这个词，并告诉你什么时候讨论会高高峰。）
帮你观察旅游机票和购物优惠信息。
抓取任意网站并在发生变化时电子邮件通知你。
连接到 Adioso, HipChat, Basecamp, Growl, FTP, IMAP, Jabber, JIRA, MQTT, nextbus, Pushbullet, Pushover, RSS, Bash, Slack, StubHub, translation APIs, Twilio, Twitter, Wunderground, and 微博等第三方.
发送和接收 WebHooks。
其它很多很多你能想到的。

环境搭建

以 Debian 服务器为例，进行环境搭建（大家可以选择购买VPS）。

概述

Huginn 的安装主要包括以下组件：

Packages / Dependencies
Ruby
System Users
Database
Huginn
Nginx

1. Packages / Dependencies

Debian 中 sudo 并没有默认安装。确保你的系统是最新的，然后安装它。

# run as root!
apt-get <span class="hljs-keyword">update</span> -y
apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">upgrade</span> -y
apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> sudo -y

# run as root!

apt-get update -y

apt-get upgrade -y

apt-get install sudo -y

注意：在安装过程中，需要手动编辑一些文件。如果你熟悉 vim，请使用下面的命令将其设置为默认编辑器。如果你对 vim 不熟悉，请跳过此操作并继续使用默认编辑器。

# <span class="hljs-keyword">Install</span> vim <span class="hljs-keyword">and</span> <span class="hljs-keyword">set</span> <span class="hljs-keyword">as</span> <span class="hljs-keyword">default</span> editor
sudo apt-<span class="hljs-keyword">get</span> <span class="hljs-keyword">install</span> -y vim
sudo <span class="hljs-keyword">update</span>-alternatives <span class="hljs-comment">--set editor /usr/bin/vim.basic</span>

# Install vim and set as default editor

sudo apt-get install -y vim

sudo update-alternatives --set editor /usr/bin/vim.basic

导入 node.js 库 (如果是 Ubuntu 或者 Debian Jessie 的话可以跳过)：

curl -sL <span class="hljs-string">https:</span><span class="hljs-comment">//deb.nodesource.com/setup_0.12 | sudo bash -</span>

1	curl -sL <span class="hljs-string">https:</span><span class="hljs-comment">//deb.nodesource.com/setup_0.12 \| sudo bash -</span>

安装需要的 packages：

sudo apt-get <span class="hljs-keyword">install</span> -y runit <span class="hljs-keyword">build</span>-essential git zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev curl openssh-<span class="hljs-keyword">server</span> checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev logrotate python-docutils pkg-config cmake nodejs graphviz

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

由于 Debian Stretch 的 runit 不会自动启动，但是这会被init系统处理。另外，Ruby需要 OpenSSL 1.0 开发包而不是 1.1的。对于默认安装使用这些包：

sudo apt-<span class="hljs-keyword">get</span> install -y runit-systemd libssl1.<span class="hljs-number">0</span>-dev

1	sudo apt-<span class="hljs-keyword">get</span> install -y runit-systemd libssl1.<span class="hljs-number">0</span>-dev

2. Ruby

在生产中使用带有 Huginn 的 Ruby 版本管理器（如 RVM，rbenv 或 chruby）会频繁导致难以诊断的问题。版本管理器不受支持，我们强烈建议所有人按照以下说明使用系统 Ruby。

如果存在的话，删除旧版本的 Ruby：

<span class="hljs-selector-tag">sudo</span> <span class="hljs-selector-tag">apt-get</span> <span class="hljs-selector-tag">remove</span> <span class="hljs-selector-tag">-y</span> <span class="hljs-selector-tag">ruby1</span><span class="hljs-selector-class">.8</span> <span class="hljs-selector-tag">ruby1</span><span class="hljs-selector-class">.9</span>

sudo apt-get remove -y ruby1.8 ruby1.9

下载 Ruby，然后编译：

mkdir /tmp/ruby &amp;&amp; cd /tmp/ruby
curl -L --progress http:<span class="hljs-comment">//cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.2.tar.bz2 | tar xj</span>
cd ruby<span class="hljs-number">-2.4</span><span class="hljs-number">.2</span>
./configure --disable-install-rdoc
<span class="hljs-built_in">make</span> -j<span class="hljs-string">`nproc`</span>
sudo <span class="hljs-built_in">make</span> install

mkdir /tmp/ruby && cd /tmp/ruby

curl -L --progress http://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.2.tar.bz2 | tar xj

cd ruby-2.4.2

./configure --disable-install-rdoc

make -j`nproc`

sudo make install

安装 bundler 和 foreman:

<span class="hljs-attribute">sudo</span> gem install rake bundler foreman --<span class="hljs-literal">no</span>-ri --<span class="hljs-literal">no</span>-rdoc

1	<span class="hljs-attribute">sudo</span> gem install rake bundler foreman --<span class="hljs-literal">no</span>-ri --<span class="hljs-literal">no</span>-rdoc

3. System Users

为 Huginn 创建一个用户：

<span class="hljs-attribute">sudo</span> adduser --disabled-login --gecos <span class="hljs-string">'Huginn'</span> huginn

1	<span class="hljs-attribute">sudo</span> adduser --disabled-login --gecos <span class="hljs-string">'Huginn'</span> huginn

4. Database

安装数据库

sudo apt-<span class="hljs-keyword">get</span> install -y mysql-server mysql-client libmysqlclient-dev

<span class="hljs-meta"># 选择一个 MySQL root 密码 (可以任意), 输入并按回车,</span>
<span class="hljs-meta"># 重复输入 MySQL root 密码 然后按回车</span>

sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

# 选择一个 MySQL root 密码 (可以任意), 输入并按回车,

# 重复输入 MySQL root 密码然后按回车

对于 Debian Stretch, 替换 libmysqlclient-dev 为 default-libmysqlclient-dev。

检查你安装的 MySQL 版本：

mysql <span class="hljs-comment">--version</span>

1	mysql <span class="hljs-comment">--version</span>

<span class="hljs-attribute">sudo</span> mysql_secure_installation

1	<span class="hljs-attribute">sudo</span> mysql_secure_installation

<span class="hljs-attribute">mysql</span> -u root -p

<span class="hljs-comment"># 输入 MySQL root 密码</span>

mysql -u root -p

# 输入 MySQL root 密码

为 Huginn 创建一个用户，替换命令中的 $password 为你真实的密码：

mysql&gt; CREATE USER <span class="hljs-string">'huginn'</span>@<span class="hljs-string">'localhost'</span> IDENTIFIED BY <span class="hljs-string">'$password'</span>;

1	mysql> CREATE USER <span class="hljs-string">'huginn'</span>@<span class="hljs-string">'localhost'</span> IDENTIFIED BY <span class="hljs-string">'$password'</span>;

支持 long indexes，你需要确保可以使用 InnoDB engine：

mysql&gt; SET default_storage_engine=INNODB;

# 如果失败，检查你的 MySQL 配置文件 (e.g. <span class="hljs-string">`/etc/mysql/*.cnf`</span>, <span class="hljs-string">`/etc/mysql/conf.d/*`</span>)
# 设置 <span class="hljs-string">"innodb = off"</span>

mysql> SET default_storage_engine=INNODB;

# 如果失败，检查你的 MySQL 配置文件 (e.g. `/etc/mysql/*.cnf`, `/etc/mysql/conf.d/*`)

# 设置 "innodb = off"

给予 Huginn 用户必要的数据库相关权限：

mysql&gt; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, <span class="hljs-keyword">INDEX</span>, ALTER, LOCK TABLES <span class="hljs-keyword">ON</span> `huginn_production`.* <span class="hljs-keyword">TO</span> <span class="hljs-string">'huginn'</span>@<span class="hljs-string">'localhost'</span>;

mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, LOCK TABLES ON `huginn_production`.* TO 'huginn'@'localhost';

退出 database 会话：

mysql&gt; \q

mysql> \q

尝试使用新的用户链接到新的数据库

<span class="hljs-attribute">sudo</span> -u huginn -H mysql -u huginn -p -D huginn_production

<span class="hljs-comment"># Type the password you replaced $password with earlier</span>

sudo -u huginn -H mysql -u huginn -p -D huginn_production

# Type the password you replaced $password with earlier

你应该回看到 ERROR 1049 (42000): Unknown database 'huginn_production'，这是正常的，因为我们会稍后创建数据库。

5. Huginn

Clone 源代码

# We'll <span class="hljs-keyword">install</span> Huginn <span class="hljs-keyword">into</span> the home <span class="hljs-keyword">directory</span> <span class="hljs-keyword">of</span> the <span class="hljs-keyword">user</span> <span class="hljs-string">"huginn"</span>

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

重要： 取消注释 RAILS_ENV 设置，以便于在生产环节运行 Huginn。

<span class="hljs-attr">RAILS_ENV</span>=production

1	<span class="hljs-attr">RAILS_ENV</span>=production

如果需要改变 Unicorn 配置：

<span class="hljs-comment"># Increase the amount of workers if you expect to have a high load instance.</span>
<span class="hljs-comment"># 2 are enough for most use cases, if the server has less then 2GB of RAM</span>
<span class="hljs-comment"># decrease the worker amount to 1</span>
<span class="hljs-attribute">sudo</span> -u huginn -H editor config/unicorn.rb

# 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

重要：确保 .env 和 unicorn.rb 都符合你的配置。

安装 Gems

sudo -u huginn -H bundle <span class="hljs-keyword">install</span> <span class="hljs-comment">--deployment --without development test</span>

1	sudo -u huginn -H bundle <span class="hljs-keyword">install</span> <span class="hljs-comment">--deployment --without development test</span>

初始化 Database

# <span class="hljs-keyword">Create</span> the <span class="hljs-keyword">database</span>
sudo -u huginn -H bundle exec rake db:<span class="hljs-keyword">create</span> RAILS_ENV=production

# Migrate <span class="hljs-keyword">to</span> the latest <span class="hljs-keyword">version</span>
sudo -u huginn -H bundle exec rake db:migrate RAILS_ENV=production

# <span class="hljs-keyword">Create</span> <span class="hljs-keyword">admin</span> <span class="hljs-keyword">user</span> <span class="hljs-keyword">and</span> example agents <span class="hljs-keyword">using</span> the <span class="hljs-keyword">default</span> <span class="hljs-keyword">admin</span>/<span class="hljs-keyword">password</span> login
sudo -u huginn -H bundle exec rake db:<span class="hljs-keyword">seed</span> RAILS_ENV=production SEED_USERNAME=<span class="hljs-keyword">admin</span> SEED_PASSWORD=<span class="hljs-keyword">password</span>

# 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

编译 Assets

sudo -u huginn -H bundle <span class="hljs-keyword">exec</span> rake assets:precompile RAILS_ENV=production

1	sudo -u huginn -H bundle <span class="hljs-keyword">exec</span> rake assets:precompile RAILS_ENV=production

安装初始脚本

Huginn 使用 foreman 来生成基于 Procfile 的初始化脚本。

编辑 Procfile 来针对生产选择一个推荐的版本。

<span class="hljs-attribute">sudo</span> -u huginn -H editor Procfile

1	<span class="hljs-attribute">sudo</span> -u huginn -H editor Procfile

注释这两行：

web: bundle <span class="hljs-built_in">exec</span> rails server -p <span class="hljs-variable">${PORT-3000}</span> -b <span class="hljs-variable">${IP-0.0.0.0}</span>
<span class="hljs-built_in">jobs</span>: bundle <span class="hljs-built_in">exec</span> rails runner bin/threaded.rb

1 2	web: bundle <span class="hljs-built_in">exec</span> rails server -p <span class="hljs-variable">${PORT-3000}</span> -b <span class="hljs-variable">${IP-0.0.0.0}</span> <span class="hljs-built_in">jobs</span>: bundle <span class="hljs-built_in">exec</span> rails runner bin/threaded.rb

取消注释这几行或者这些

<span class="hljs-meta"># web: bundle exec unicorn -c config/unicorn.rb</span>
<span class="hljs-meta"># jobs: bundle exec rails runner bin/threaded.rb</span>

1 2	<span class="hljs-meta"># web: bundle exec unicorn -c config/unicorn.rb</span> <span class="hljs-meta"># jobs: bundle exec rails runner bin/threaded.rb</span>

Export 初始化 scripts:

sudo bundle <span class="hljs-built_in">exec</span> rake production:<span class="hljs-built_in">export</span>

1	sudo bundle <span class="hljs-built_in">exec</span> rake production:<span class="hljs-built_in">export</span>

注意：每次你修改了 .env 或者你的 procfile 文件，你都必须要重新 export 出事 script。

设置 Logrotate

sudo cp deployment<span class="hljs-meta-keyword">/logrotate/</span>huginn <span class="hljs-meta-keyword">/etc/</span>logrotate.d/huginn

1	sudo cp deployment<span class="hljs-meta-keyword">/logrotate/</span>huginn <span class="hljs-meta-keyword">/etc/</span>logrotate.d/huginn

确保你的 Huginn 实例正在运行

sudo bundle exec rake production:status

6. Nginx

注意：Nginx 是 Huginn 官方支持的 web 服务器。如果你不会或者不想使用 Nginx 作为你的 web 服务器，参考 wiki 的文章来使用配置 apache

安装

sudo apt-<span class="hljs-keyword">get</span> install -y nginx

1	sudo apt-<span class="hljs-keyword">get</span> install -y nginx

网站配置

复制示例网站配置：

sudo cp deployment<span class="hljs-meta-keyword">/nginx/</span>huginn <span class="hljs-meta-keyword">/etc/</span>nginx<span class="hljs-meta-keyword">/sites-available/</span>huginn
sudo ln -s <span class="hljs-meta-keyword">/etc/</span>nginx<span class="hljs-meta-keyword">/sites-available/</span>huginn <span class="hljs-meta-keyword">/etc/</span>nginx<span class="hljs-meta-keyword">/sites-enabled/</span>huginn

sudo cp deployment/nginx/huginn /etc/nginx/sites-available/huginn

sudo ln -s /etc/nginx/sites-available/huginn /etc/nginx/sites-enabled/huginn

确保编辑配置文件以匹配你的设置，如果你正在运行多个nginx站点，请从 listen 指令中删除 default_server 参数：

<span class="hljs-comment"># Change YOUR_SERVER_FQDN to the fully-qualified</span>
<span class="hljs-comment"># domain name of your host serving Huginn.</span>
<span class="hljs-attribute">sudo</span> editor /etc/nginx/sites-available/huginn

# Change YOUR_SERVER_FQDN to the fully-qualified

# domain name of your host serving Huginn.

sudo editor /etc/nginx/sites-available/huginn

如果 huginn 是唯一可用的 nginx 网站，删除默认的 nginx 网站：

sudo rm <span class="hljs-regexp">/etc/</span>nginx<span class="hljs-regexp">/sites-enabled/</span><span class="hljs-keyword">default</span>

1	sudo rm <span class="hljs-regexp">/etc/</span>nginx<span class="hljs-regexp">/sites-enabled/</span><span class="hljs-keyword">default</span>

Restart

<span class="hljs-attribute">sudo</span> service nginx restart

1	<span class="hljs-attribute">sudo</span> service nginx restart

完成。
