deploy_rails_centos.sh

如果需要指定Rails环境，例如production，可以输入  RAILS_ENV=production rake db:create db:migrate

# listen 80 default_server;
The argument default_server means this virtual host will answer requests on port 80 that don’t specifically match another virtual host’s listen statement. 

# listen [::]:80 default_server ipv6only=on;
 The second statement listens over IPv6 and behaves in the same way.
 
删除Gemfile中unicorn的注释
bundle

注意unicron的权限

mysql安装后修改默认编码格式

SHOW VARIABLES LIKE 'character%';
