Configuring SELinux for Nginx/Apache

https://t.me/linuxmalaysiamy/175

# Allow nginx or apache to access public files of web application and communicate
# /var/www/zammad/public/ as example, change it.
# AlmaLinux, Rocky Linux, Oracle Linux and Centos

chcon -Rv --type=httpd_sys_content_t /var/www/zammad/public/
setsebool httpd_can_network_connect on -P
semanage fcontext -a -t httpd_sys_content_t /var/www/zammad/public/
restorecon -Rv /var/www/zammad/public/

# Check for the port using http in the list
#
semanage port -l | grep http

# Add the http port needed

semanage port -a -t http_port_t -p tcp 9000
semanage port -a -t http_port_t -p tcp 9001

(Will hit error for port 9001 if the policy exist, can be ignore)

# Restart nginx and related services just to make sure and check the logs.

# Using nginx as proxy to different host

setsebool -P httpd_can_network_relay 1
setsebool -P httpd_can_network_connect 1

# # # #

# # Dont use this # # semanage permissive -a httpd_t

Detail explanation of each command in the context of configuring SELinux for allowing a web server (like nginx or Apache) to access and communicate with the necessary resources.

Improve Website Performance with Brotli Compression

Brotli compression, an open-source algorithm by Google, significantly reduces file sizes compared to traditional methods like Gzip. This leads to faster website loading times, a smoother user experience, and potentially lower bandwidth usage.

We can check our web browsing is using Brotli Compression using this online tools.

https://tools.keycdn.com/brotli-test

and

https://www.brotli.pro/

Benefits of Brotli Compression

Reduced File Sizes: Studies show Brotli can achieve up to 26% better compression than Gzip. Faster Loading Times: Smaller files download quicker, resulting in faster page loads. Lower Bandwidth Usage: Reduced file sizes mean less data transfer, benefiting users with limited data plans.
Efficient CPU Usage: Brotli offers better compression with lower CPU usage compared to Gzip.

Requirements and Support

Brotli requires an HTTPS connection and is already supported by most modern browsers (Chrome, Firefox, Opera).

Enabling Brotli Compression is need to be done at server level.

For implementation instructions, refer to the official guides:

Nginx Brotli Compression Setup
