General steps to replace unicorn in old projects

The general steps for the old project to replace Unicorn:

(1) Modify config/Application.rb
Delete
# assign log4r ' s logger as rails ' logger.
Log4r_config= Yaml.load_file (File.join (File.dirname (__file__), "Log4r.yml"))
Yamlconfigurator.decode_yaml (log4r_config[' log4r_config ')
Config.logger = log4r::logger[rails.env]
New configuration for memcached
Config.cache_store =:d Alli_store, *settings.memcached.servers,
{: namespace = Settings.memcached.namespace,: Compress = true}

(2) Create a new config/deploy/folder,
New PRODUCTION.RB
Staging.rb

(3) New config/environments/
Development.rb
Production.rb
Staging.rb
Test.rb

(4) Modify gemfile, delete thin, add unicorn
Panax Notoginseng Gem ' Dalli '
The Gem ' unicorn '
39
Group:test,:d evelopment do
The gem "Rspec-rails", ">= 2.5.0"
Gem ' Factory_girl ', ' 2.6.4 '
Gem ' factory_girl_rails ', ' 1.7.0 '
The Gem ' Faker ', ' 1.1.2 '
Gem ' forgery ', ' 0.5.0 '
The Gem ' magic_encoding ', ' 0.0.2 '
The Gem ' Email_spec ', ' 1.4.0 '
48
Net-ssh ', ' ~> 2.0 '
Gem ' Capistrano ', ' ~> 2.15.7 '
Wuyi Gem ' capistrano-rbenv ', ' 1.0.5 '
The Gem ' rb-readline ', ' 0.4.2 '
The end

(5) Modify the configuration of the configuration config/settings.yml
181 memcached:
182 namespace:xxx-xxxxx-cms-staging
183 Servers:
184-127.0.0.1:11215

(6) Configuring the Config/deploy.rb file

(7) Bundle EXEC Cap Deploy:setup
Bundle EXEC Cap Deploy:cold

Deployment issues that may occur
(1) Could not parse object (due to set:repository caused by writing the wrong config/deploy.rb)


(2) CONFIG/APPLICATION.RB configuration is not automatically recognized uninitialized constant cms::application::settings
Modified Gemfile, Gem "Rails_config", ' 0.3.4 '


(3)/home/wz/.rbenv/versions/1.9.3-p545/lib/ruby/gems/1.9.1/gems/activesupport-3.0.8/lib/active_support/ Cache.rb:65:in ' Rescue in Lookup_store ': Could not the find cache store adapter for Dalli_store (cannot load such file--ACTI Ve_support/cache/dalli_store) (RuntimeError)
Need to add

Gem ' Dalli '

The final step is to make a soft link to the Nginx configuration in the project folder directory.
$ nginx-t
Nginx:the configuration file/opt/nginx/conf/nginx.conf syntax is OK
