Recently I was assigned to a task about adding a file upload feature to a existing nginx server on CentOS. Nginx was chosen years ago because it simply handles some static files only. If the file upload was a requirement, using apache is simpler as computation power isn’t a constraint in our case.
Background
- CentOS 7
- nginx 1.10.2
- nginx-upload-module
- ngx_http_auth_pam_module
Compile Dynamic modules
Download upload and auth pam module source code. Then find out the current nginx version, download the source code and compile modules
