如何更改自定义游民箱的php和mysql设置

Question

I use this vagrant box to develop on local pc for magento. Magento works too slow and I have to adjust the settings. There is not much documentation about how to change php and mysql settings. Plus I'm very very beginner at subject.

Do I edit the setting inside the server with ssh or do I change cookbooks and then do vagrant provision or reload? If I edit inside the server can I do vagrant provision ? will it overwrite the setting that I changed in the server?

For mysql setting I changed this file to my needs but when I did vagrant up --provision after vagrant halt I got this error: (mysql did not start )

these are the settings I have changed

for ssh access, use the command:

vagrant ssh

http://docs.vagrantup.com/v2/cli/ssh.html

overwrite attributes of cookbook is the best option,add this to vagrantfile

>   config.vm.provision: chef_solo do | chef |
>      chef.cookbooks_path = "cookbooks"
>      chef.data_bags_path = "data_bags"
>      chef.json = {
>         "mysql" => {
>            "tunable" => {
>              "myisam_sort_buffer_size" => "32M"
>           }
>         },
          "php" => {
           "more attributes" => "value"
          }
>      }
>      # List of recipes to run
>      chef.add_recipe "vagrant_main"
>      chef.add_recipe "vagrant_main :: wordpress"
>      chef.add_recipe "vagrant_main :: drupal"
>      chef.add_recipe "vagrant_main :: magento"
>      chef.add_recipe "vagrant_main :: nodejs"    end
>         end end

Read the doc of cookbook (README.md) to determine the attributes to overwrite

vagrant doc:
