Deployment of rubyweb environment using nginx + unicorn

: This article describes how to deploy the rubyweb environment using nginx + unicorn. For more information about PHP tutorials, see. Recently, I took over a ruby web project. because I have never been familiar with ruby and related web development before, and there are missing documents in the project, I took some detours when deploying this project. Finally, the project is successfully deployed by referring to multiple ruby on rails development environments and learning the relationship between gem and bundler in ruby. Here is a small summary. It can also be used as a reference when ruby web development is just getting started.
Our project is based on padrino. if it is based on rails, the deployment should be similar.

1. install ruby

Because the system may have multiple ruby-related projects, and different projects may need to be developed or tested for different ruby versions, multiple ruby versions may need to be installed in the system. This requires tools to manage existing versions and install new versions. Here I use rbenv and can also use the old rvm.
Install rbenv

git clone git://github.com/sstephenson/rbenv.git  ~/.rbenvecho 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrcecho 'eval "$(rbenv init -)"' >> ~/.bashrcexec $SHELL

Add ruby-build components

git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-buildecho 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrcexec $SHELL

Add the gem-rehash component

git clone https://github.com/sstephenson/rbenv-gem-rehash.git ~/.rbenv/plugins/rbenv-gem-rehash

Install ruby (using ruby2.1.5 as an example)
Ruby installation is slow by default, so download the corresponding file from ruby.taobao.org and install it locally.

wget -O ~/.rbenv/versions/ruby-2.1.5.tar.gz http://ruby.taobao.org/mirrors/ruby/2.1/ruby-2.1.5.tar.gzenv RUBY_BUILD_MIRROR_URL=file:///home/ziven/.rbenv/versions/ruby-2.1.5.tar.gz# ~/.rbenv/bin/rbenv install 2.1.5

In this example, wgetis the downloaded rubyfile, which is ruby-2.1.5.tar.gz.

RUBY_BUILD_MIRROR_URL

Specifies the path of the installed ruby Image. The local path is used here. Note that the local path should end #.
The version after the rbenv install command should correspond to the ruby version to be installed. for example, the installed version may contain the corresponding patch number (for example, 1.9.3-p223.

2. install necessary components

Because we generally use bundler to manage the gems required by the project, we need to install bundler here.
Considering the speed of connecting ruby images in China, we replaced the gem source with the taobao source.

gem sources --remove https://rubygems.org/gem sources -a https://ruby.taobao.org/

Then execute the gem sources-l, which should only be https://ruby.taobao.org/this source
Install bundler

gem install bundler

3. Application Deployment

A. clone the web source code to a proper location

Assume that the cloned source code is stored in/opt/projectA.

B. install the dependent gems

Run the following command in the root directory of the project:

bundle install

Note that the commands executed may be slightly different depending on the situation. For example, you may need to execute

bundle install --deployment --without development test

In this way, the related dependent gems is installed under projectA/vendor/bundle. It is especially suitable for different projects that depend on different versions of the same gem.

C. database migration

Because this project is based on padrino, you need to execute:

padrino rake --envir db:migrate

Note that bundle may be used to execute the command as needed:

bundle exec padrino rake --envir db:migrate

After the database is successfully migrated, you need to create an amdin account. Padrino creates the admin account in db/seeds. rb by default. Therefore, run the following command:

bundle exec padrino rake --envir seed

During execution, the system prompts you to enter the admin account's email address and password.

D. unicorn deployment

The corresponding unicorn startup script may be required here. you can refer to unicorn. rb of ruby-china. Here is a brief description.
Start unicorn server:

bundle exec unicorn -E production -c unicorn.rb -D

In this way, the padrino server is started normally. If unicorn. rb is listening for the tcp port, the corresponding url should be accessible. If you use the unix socket listening method, you should also use nginx (or apache) for reverse proxy.

4. install and configure nginx

A. install nginx

Nginx can be installed by installing common linux software. We recommend that you use the source code installation method. The installation method of package manager is as follows:

sudo apt-get install nginx-full

B. nginx configuration

upstream myserver {  server unix:/tmp/projectA.sock fail_timeout=0;}server {    listen       7788;    server_name  localhost;    client_max_body_size 10M;    error_page   500 502 503 504  /50x.html;    location = /50x.html {        root   /usr/share/nginx/html;    }    root /opt/projectA/web/public;    try_files $uri $uri.html @app;    location @app {        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;        proxy_set_header Host $http_host;        proxy_redirect off;        proxy_pass http://myserver;    }}

Forward requests from Port 7788

unix:/tmp/projectA.sock

. That is, it is forwarded to our web server for processing.
Now, the server is running properly. Other auxiliary functions can be added as needed. For example, nginx may require an ssl certificate for authentication.
The deployment of the ruby on rails project is similar. during the deployment process, you may need to make corresponding adjustments when executing the corresponding commands. However, as long as you are familiar with the deployment method of ruby web, other documents that can be referenced in the relevant framework are relatively easy to deploy.

The preceding section describes how to deploy the ruby web environment using nginx + unicorn, including some content. I hope to help some friends who are interested in the PHP Tutorial.
