Nginx Log Rotation Script

This Bash script is designed to manage and rotate Nginx log files. It ensures that logs are periodically backed up, cleared, and maintained efficiently by keeping only the latest backups.

• Sets up paths for access and error logs.
• Specifies a directory for storing log backups.

• Checks if the `access.log` and `error.log` exist.
• If either file is missing, the script exits with an error.

• Creates a timestamp (`YYYYMMDDHHMMSS`) for log backups.
• Copies the current logs to the backup directory with a timestamp suffix.

• Ensures the backup process was successful.
• If the backup fails, the script exits with an error.

• Empties the access and error logs to free up space.

• Keeps only the latest 7 backups.
• Deletes older backups beyond the set limit.

• You can find the Script on Gitlab via this link

1. Clone the Scrlipt via the git link

$ git clone git@git.elosys.net:sys/bin.git 

1. Make it executable

sudo chmod +x nginx_rotation.sh

1. Automate it with a cron job to run periodically

sudo cronjob -e

• you can add this line which executes the script every third day :

40 1 */3 * * /home/admin/bin/gitlab_log_rotation.sh

This script automates the log rotation process for Nginx logs by ensuring efficient backup and cleanup. By maintaining only the last 7 backups, it helps manage disk space while ensuring log history is available when needed.
