Question

操作系统 - Ubuntu 16 日期 - 11/06/2017

我尝试在本地计算机上安装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

安装Postgres
```
a. sudo apt-get install postgresql-9.3
```
但我收到了错误

（＆＃39; postgresql-9.3＆＃39;没有安装候选人）

所以，我使用了下面的命令
```
a. sudo apt-get update
b. sudo apt-get install postgresql postgresql-contrib
```

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

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

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

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 - 红宝石宝石

Bundler和Canvas依赖项

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

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

  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

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)

数据库配置

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

已更改From -

--# 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

到这个

--# 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

发送邮件配置

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

网址配置

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

安全配置一个。 cp config / security.yml.example config / security.yml 湾nano config / 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

从此 -

--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

到此 -

--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 - 无论我在那里得到同样的错误

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

无法访问＆public; / dist / brandable_css＆＃39;：没有此类文件或目录

我被困在这里，请帮忙

谢谢！

根据冗长的一系列评论快速回答这个问题。

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

加密密钥太短，请参阅security.yml.example
