Capistrano：将本地mysql数据库同步到远程mysql数据库

Posted 2021-02-26

This could be further abstracted to work with other db's. Also, it really should be using Ruby's Tempfile class instead of assuming the local machine is *NIX based, but it works :)

namespace :db do
task :sync_to_local, :roles => :web do
  sql_out = "#{environment_database}.sql"
  run "mysqldump --user #{dbuser} --password=#{dbpass} #{environment_database} > #{sql_out}"
  system "sftp #{user}@myhost.com:#{sql_out} /tmp/#{sql_out}"
  run "rm #{sql_out}"
  system "mysql -u #{dbuser} --password=#{dbpass} mydatabase_development < /tmp/#{sql_out}"
  system "rm /tmp/#{sql_out}"
end
end
 
# invoked: cap production db:sync_to_local
