If you are running Security-Enhanced Linux, then it might be the reason for the problem, by denying access to the file from the server.



To check whether SELinux is enabled on your system, run the sestatus command in a terminal. If the command does not exist, then SELinux is not on your system. If it does exist, then it should tell you whether it is enforced or not.



To check whether SELinux policies are the reason for the problem, you can try turning it off temporarily. However be CAREFUL, since this will disable protection entirely. Do not do this on your production server.


setenforce 0



If you no longer have the problem with SELinux turned off, then this is the root cause.



To solve it, you will have to configure SELinux accordingly.



The following context types will be necessary :


    

  • httpd_sys_content_t for files that you want your server to be able to read
    • 

  • httpd_sys_rw_content_t for files on which you want read and write access
    • 

  • httpd_log_t for log files
    • 

  • httpd_cache_t for the cache directory
    • 




For example, to assign the httpd_sys_content_t context type to your website root directory, run :


semanage fcontext -a -t httpd_sys_content_t "/path/to/root(/.*)?"
restorecon -Rv /path/to/root



If your file is in a home directory, you will also need to turn on the httpd_enable_homedirs boolean :


setsebool -P httpd_enable_homedirs 1



In any case, there could be a variety of reasons why SELinux would deny access to a file, depending on your policies. So you will need to enquire into that. Here is a tutorial specifically on configuring SELinux for a web server.

Flutter for Single-Page Scrollable Websites with Navigator 2.0

Image
  Single page scrollable websites are everywhere. In this website design pattern, all the content is presented in one long-scrolling layout that contains multiple sections. Visitors can scroll or jump to a section by clicking buttons of a sticky menu. This pattern is a good fit for small content such as brochure websites, software library documentation, portfolios, and landing pages that are used to convert users [ 1 ]. Designers also love this pattern because it is simple, clean, and enables cool scroll animations. Jetbrains Mono single-page scrollable website Hive docs multi-page scrollable website In this series of articles, we will explore how to build a  single-page scrollable website  using Flutter. We will benefit from the Navigator 2.0 API to provide a good navigation experience to the users. You can find the source code of this series’ sample apps on my  Github page .

Better File Storage in Oracle Cloud

Use Oracle Application Express with Oracle Cloud Infrastructure REST APIs to upload, download, and manage big files in Oracle Cloud. By Adrian Png November 27, 2019 Oracle Cloud Infrastructure  provides a comprehensive suite of REST APIs for accessing and managing cloud resources. For example, administrators can use REST APIs to create and manage autonomous databases and initiate backups. Oracle Application Express (Oracle APEX)  makes working with REST easy. The  APEX_WEB_SERVICE  package, available since Oracle APEX 4.0, provides developers with a function for consuming REST APIs. Oracle APEX 5.0 introduced the  APEX_JSON  package, allowing easy parsing of JSON responses. Oracle APEX 18.1 introduced the Web Source Module (WSM), which enables developers to access REST services and use the data in APEX components such as reports, interactive reports, and interactive grids. These features, when used together with Oracle Cloud Infrastructure REST APIs, enable APEX developers
