检查 Redis 服务版本

自 2013-10-05 版本之后，需要升级 Redis 2.6 版本以上，可通过如下命令查看当前 Redis Server 版本：

> redis-server -v

Prepare to Upgrade

1. Fetch all new updates first:

> su canvas
> git fetch origin

2. Find out what is the current branch:

> git branch

It will return something like this:

HEAD detached at origin/stable/2022-03-02

> git fetch && git reset --hard origin/prod

3. 成功拉取 git 更新之后，准备升级和安装依赖库：

> bundle update
> bundle install

bundle 升级过程中，如需删除缓存，可参考该路径：/data/canvas/vendor/bundle/ruby/x.x.x/cache/bundler/ 删除缓存

4. Add GEM_HOME Path:

nano ~/.basrhc
export GEM_HOME="$HOME/.rbenv/versions/$(rbenv version-name)"

Compiled Assets

RAILS_ENV=production $GEM_HOME/bin/bundle exec rake canvas:compile_assets
