To achieve your goal of deploying updates with a different user while maintaining the correct ownership for the web server, you can use a combination of user groups and Access Control Lists (ACLs). Here's a step-by-step guide:
-
Create a User Group:
First, create a new group that includes both
wwwandmy_user. This will allowmy_userto have the necessary permissions to update files.sudo groupadd webdev sudo usermod -aG webdev www sudo usermod -aG webdev my_user -
Set Group Ownership:
Change the group ownership of the
/www/wwwroot/directory to the new groupwebdev.sudo chown -R :webdev /www/wwwroot/ -
Set Directory Permissions:
Ensure that the group has the necessary permissions to read, write, and execute within the directory.
sudo chmod -R 775 /www/wwwroot/ -
Use ACLs for Fine-Grained Control:
Set up ACLs to ensure that
my_usercan write to the directory, and that new files created bymy_userwill be owned by thewwwuser.sudo setfacl -R -m u:my_user:rwx /www/wwwroot/ sudo setfacl -R -m d:u:www:rwx /www/wwwroot/The
-Rflag applies the ACLs recursively,-mmodifies the ACL, and-dsets default ACLs for new files. -
Deploy Updates:
Now,
my_usercan deploy updates to the/www/wwwroot/directory. After deployment, ensure that the files are owned by thewwwuser:sudo chown -R www:www /www/wwwroot/ -
Verify Permissions:
After setting up, verify that the permissions are correctly applied:
getfacl /www/wwwroot/
This setup allows my_user to deploy updates while ensuring that the web server continues to function correctly with the necessary file ownership and permissions.
