加密密钥太短，见 security.yml.example

Question

操作系统 - Ubuntu 16 日期 - 2017 年 11 月 6 日

我正在尝试在我的本地计算机上安装 Canvas LMS。

关注"https://github.com/instructure/canvas-lms/wiki/Production-Start"此链接

第一步 - 数据库安装和配置

1. 安装 Postgres

   a. sudo apt-get install postgresql-9.3
   

   但我遇到了一个错误

   （'postgresql-9.3'没有安装候选）

   所以，我使用了下面的命令

   a. sudo apt-get update
   b. sudo apt-get install postgresql postgresql-contrib
   

2. 配置Postgres

   a. sudo -u postgres createuser canvas --no-createdb \
     --no-superuser --no-createrole --pwprompt (i set password `'portal'`)
   
   b. sudo -u postgres createdb canvas_production --owner=canvas
   

第二步 - 获取代码

1. 使用 Git

   a. sudo apt-get install git-core
   b. git clone https://github.com/instructure/canvas-lms.git canvas
   c. cd canvas
   d. git branch --set-upstream-to origin/stable
   

2. 代码安装

   a. sudo mkdir -p /var/canvas
   b. sudo chown -R anup /var/canvas
   c. cd canvas
   d. sudo cp -av . /var/canvas
   e. cd /var/canvas
   

第三步 - 依赖安装

1. 外部依赖

   a. sudo apt-get install software-properties-common
   b. sudo apt-add-repository ppa:brightbox/ruby-ng
   c. sudo apt-get update
   
   d. sudo apt-get install ruby2.4 ruby2.4-dev zlib1g-dev libxml2-dev \
                  libsqlite3-dev postgresql libpq-dev \
                  libxmlsec1-dev curl make g++
   
   e. curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
   f. sudo apt-get install nodejs
   
   g. sudo -u postgres createuser ultron
   h. sudo -u postgres psql -c "alter user ultron with superuser" postgres
   

第四步 - 红宝石

1. Bundler 和 Canvas 依赖项

   a. sudo gem install bundler --version 1.13.6
   b. bundle install --path vendor/bundle
   

2. Yarn安装

   a. curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
   b. echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
   
   c. sudo apt-get update && sudo apt-get install --allow-downgrades yarn=0.27.5-1 (Cause i'm using Ubuntu 16)
   
   d. sudo apt-get install python
   
   e. yarn install  
   

第五步 - 画布默认配置

1.   a. for config in amazon_s3 database \
      delayed_jobs domain file_store outgoing_mail security external_migration; \
    do cp config/$config.yml.example config/$config.yml; done
   

2. 动态设置配置

     a. cp config/dynamic_settings.yml.example config/dynamic_settings.yml
     b. nano config/dynamic_settings.yml (Haven't Changed anything)
   

3. 数据库配置

     a. cp config/database.yml.example config/database.yml
     b. nano config/database.yml
   

已经从 -

--# do not create a queue: section for your test environment
--test:
--  adapter: postgresql
--  encoding: utf8
--  database: canvas_test
--  host: localhost
--  username: canvas
--  timeout: 5000
--
--development:
--  adapter: postgresql
--  encoding: utf8
--  database: canvas_development
--  timeout: 5000

--production:
--  adapter: postgresql
--  encoding: utf8
--  database: canvas_production
--  host: localhost
--  username: canvas
--  password: portal
--  timeout: 5000

到这里

--# do not create a queue: section for your test environment
--test:
--  adapter: postgresql
--  encoding: utf8
--  database: canvas_test
--  host: localhost
--  username: canvas
--  timeout: 5000

--development:
--  adapter: postgresql
--  encoding: utf8
--  database: canvas_production
--  host: localhost
--  username: canvas
--  password: portal
--  timeout: 5000

--production:
--  adapter: postgresql
--  encoding: utf8
--  database: canvas_production
--  host: localhost
--  username: canvas
--  password: portal
--  timeout: 5000

4. 外发邮件配置

   a. cp config/outgoing_mail.yml.example config/outgoing_mail.yml
   b. nano config/outgoing_mail.yml (Haven't Changed anything)
   

5. 网址配置

   a. cp config/domain.yml.example config/domain.yml
   b. nano config/domain.yml
   

6. 安全配置 一个。 cp 配置/security.yml.example 配置/security.yml 湾。纳米配置/security.yml

第六步 - 生成资产

  1. 
    a. cd /var/canvas
    b. mkdir -p log tmp/pids public/assets app/stylesheets/brandable_css_brands
    c. touch app/stylesheets/_brandable_variables_defaults_autogenerated.scss
    d. touch Gemfile.lock
    e. sudo chown -R anup config/environment.rb log tmp public/assets \

    app/stylesheets/_brandable_variables_defaults_autogenerated.scss \
                          app/stylesheets/brandable_css_brands Gemfile.lock config.ru

    f. yarn install
    g. RAILS_ENV=production bundle exec rake canvas:compile_assets

错误 - 加密密钥太短，请参阅 security.yml.example，所以我 更改了 sequrity.yml.example

从这里-

--production:
--  # replace this with a random string of at least 20 characters
--  encryption_key: 12345

--development:
--  encryption_key: facdd3a131ddd8988b14f6e4e01039c93cfa0160
--  previous_encryption_keys:
--    - 0610afc39c93010e4e6f41b8898ddd131a3ddcaf

--test:
--  encryption_key: facdd3a131ddd8988b14f6e4e01039c93cfa0160

到这里-

--production:
--  # replace this with a random string of at least 20 characters
--  encryption_key: facdd3a131ddd8988b14f6e4e01039c93cfa0160
--development:
--  encryption_key: facdd3a131ddd8988b14f6e4e01039c93cfa0160
--  previous_encryption_keys:
--    - 0610afc39c93010e4e6f41b8898ddd131a3ddcaf

--test:
--  encryption_key: facdd3a131ddd8988b14f6e4e01039c93cfa0160

问题未解决 - 无论我放在那里都会得到相同的错误

    h. sudo chown -R anup public/dist/brandable_css
Getting this error - 

无法访问“public/dist/brandable_css”：没有这样的文件或目录

我卡在这里，请帮助

谢谢！

根据冗长的 cmets 系列快速回答问题。

需要编辑文件security.yml，而不是security.yml.example。
