Install RVM

You typically use RVM or rbenv to install Ruby, where you choose RVM.

$ Curl-ssl Https://get.rvm.io | Bash-s Stable

Load into RVM:

$ SOURCE/HOME/LIBUCHAO/.RVM/SCRIPTS/RVM
$ rvm-v
RVM 1.25.12 (Stable) by Wayne E. Seguin <wayneeseguin@gmail. Com> ...

Then execute the following command:

$ type RVM
RVM is a function
...

Description RVM installed correctly.
Install Ruby

Installing Ruby with RVM

$ RVM Install 2.1.0
$ RVM Use 2.1.0--default
$ ruby-v
Ruby 2.1.0p0

Domestic server recommended to replace the RubyGems to Taobao Mirror

$ gem sources-r https://rubygems.org/
$ gem sources-a http://ruby.taobao.org/

Otherwise, installing a Gem can be very, very slow.
Installing Rails

In fact, Rails is also a Gem

$ gem Install rails--no-ri--no-rdoc-v ...
$ rails-v
Rails 4.0.2

The Rails environment is now installed.
Installing MySQL

Install Mysql and the corresponding library files:

$ sudo apt-get install mysql-server Libmysqlclient-dev

Then do some Setup settings:

$/usr/bin/mysql_secure_installation

Create the appropriate database and give it a new user with a small number of permissions:

mysql> CREATE DATABASE blix_production;
Mysql> GRANT all privileges on the blix_production.* to Blix@localhost identified by "123456";
mysql> flush Privileges;
Mysql> exit

Import data:

$ mysql-u blix-p Blix_production < Database.sql

Install Nginx

Nginx specifically handles static requests and acts as a reverse proxy for unicorn

Edit/etc/apt/sources.list, add the following two lines at the end

Deb http://nginx.org/packages/ubuntu/precise nginx
deb-src http://nginx.org/packages/ubuntu/precise nginx

Add Nginx Signature

$ wget http://nginx.org/keys/nginx_signing.key
$ sudo apt-key add Nginx_signing.key

Install Nginx

$ sudo apt-get update
$ sudo apt-get install Nginx

After the installation is complete, you can enter http://server-ipaddress in the browser to see if the installation is correct.
Configure Unicorn

First compile the static file:

$ rails_env=production Rake assets:clean
$ rails_env=production Rake assets:precompile

Unicorn Configuration Reference:

Worker_processes 2
timeout

app_path = File.expand_path (". /.. ", __file__)
working_directory app_path

listen 8080,: Tcp_nopush => true
Listen"/tmp/unicorn.sock " ,: Backlog =>

stderr_path App_path + "/log/unicorn.stderr.log" Stdout_path app_path
+ "/log/ Unicorn.stdout.log "

pid App_path +"/tmp/pids/unicorn.pid "

Unicorn from startup script:

#!/bin/sh SET-E # Example init script, this can is used with nginx, too, # since Nginx and unicorn accept the same signa
LS # Feel The following variables for your app:timeout=${timeout-60} App_root=/home/libuchao/blix App_user=libuchao pid= $APP _root/tmp/pids/unicorn.pid cmd= "unicorn_rails-d-e production-c $APP _root/config/ Unicorn.rb "action=" Set-u old_pid= "$PID.

Reopen-logs) sig USR1;;
*) echo >&2 "Usage: $ <start|stop|restart|upgrade|force-stop|reopen-logs>" Exit 1;;

 Esac

Make a soft connection to the shell under/etc/init.d/and make it boot from:

$ chmod +x/home/libuchao/blix/config/unicorn_init.sh
$ sudo ln-s/home/libuchao/blix/config/unicorn_init.sh/etc /init.d/unicorn
$ sudo update-rc.d unicorn defaults

Start Unicorn:

$ Service Unicorn Start

Enter the http://server_ipaddress:8080 view effect in the browser.
Configure Nginx

Nginx Configuration Reference:

Upstream Blix_backend {
  server unix:/tmp/unicorn.sock fail_timeout=0;
}

gzip on;
Gzip_disable "Msie6";
Client_max_body_size 150m;

server {
  listen default;
  return 403;
}

server {
  listen;
  server_name libuchao.com www.libuchao.com;

  Root/home/libuchao/blix/public;

  Try_files $uri/index.html $uri. html $uri @httpapp;

  Location @httpapp {

    Proxy_set_header  Host $host;
    Proxy_set_header  x-forwarded-host $host;
    Proxy_set_header  x-forwarded-server $host;
    Proxy_set_header  x-real-ip    $remote _addr;
    Proxy_set_header  x-forwarded-for $proxy _add_x_forwarded_for;
    Proxy_buffering on  ;

    Proxy_pass http://blix_backend;
  }

  Location ~ ^ (/assets) {
    access_log off;
    Expires   Max;
  }

This should be done directly through the domain name.
