CANVAS LMS开源系统

Canvas LMS初窥

Git

You can install Giton Debian/Ubuntu by running

$ sudo apt-get install git-core

Once you have a copy of Git installed on your system,getting the latest source for Canvas is as simple as checking out code from therepo, like so:

~$ git clone https://github.com/instructure/canvas-lms.git canvas

~$ cd canvas

~/canvas$ git checkout --track -b stable origin/stable

Docker

==========CanvasLMS 也有docker file了，那岂不是docker一下是最快的方式

ROM ruby:2.1

ENV DEBIAN_FRONTEND noninteractive

RUN curl -sLhttps://deb.nodesource.com/setup | bash -

RUN apt-get update -qq \

&& apt-get install -qqy \

locales \

nodejs \

postgresql-client \

libxmlsec1-dev \

&& rm -rf /var/lib/apt/lists/*

# Ensure UTF-8 locale

RUN echo en_US.UTF-8 UTF-8 >>/etc/locale.gen

RUN locale-gen en_US.UTF-8

ENV LANG en_US.UTF-8

ENV LC_ALL en_US.UTF-8

RUN dpkg-reconfigure locales

# Canvas requiresbundler 1.7.10

//什么是Bundler

　　Canvas uses Bundler as an additional layeron top of Ruby Gems to manage versioned dependencies. Bundler is great!

RUN gem uninstall bundler \

&& gem install bundler -v 1.7.10

RUN mkdir /app

WORKDIR /app

RUN mkdir /home/docker \

&& useradd -d /home/docker docker \

&& chown -R docker:docker /home/docker/usr/local/bundle

Core components(不涉及部署，可同一个机器)

部署过程逆向，从底向上：

Starting PostgreSQL 9.3 databaseserver 如果你安装的postsql在别的服务器，要配置下postgresql.conf / pg_hba.conf

在数据库中createuser创建默认用户canvas,然后createdb安装默认数据库

把当前系统用户加到数据库的超级用户

sudo -u postgres createuser $USER

sudo -u postgres psql -c "alter user $USER with superuser"postgres

安装代码

应用程序目录结构

RUBY

$ sudo apt-get install ruby2.1 ruby2.1-devzlib1g-dev libxml2-dev \

libsqlite3-devpostgresql libpq-dev \

libxmlsec1-dev curl make g++

Node.js

$ curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -

$ sudo apt-get install nodejs

APAChe web

Note: Some users have found that, to setup the web server, they need to addthe Phusion Passenger APT repository, which contains the passenger-common1.9.1 package, and then to install passenger, which replaces passenger-common1.9.1. After adding the new APT repository, theinstall command looks like this:

Ruby Package

sudo apt-get install rubygems

安装之后还是失败Gem找不到

root@server-zyq9z8tu:/var/canvas/lib# gem

The program 'gem' can be found in thefollowing packages:

*ruby

*rubygems

Try: apt-get install <selectedpackage>
