Automated Nginx Log Rotation and Archiving Setup (Year/Month/Day Directory Storage)

Nginx Log Rotation and Archiving Configuration Guide

This guide will help you configure an automated script to rotate Nginx logs. The script will split logs daily, store them in a year/month/day directory structure, and automatically clean up old logs.

Step 1: Download and Extract the Script

Run the following commands to download the script to /root/, extract it, and open it for editing.

cd /root/
wget https://wpquicksearch.com/wp-content/uploads/oldimg/2015/08/cut_nginx_logs.tar.gz
tar -xzvf cut_nginx_logs.tar.gz
vi cut_nginx_logs.sh

Step 2: Edit the Script Configuration

In the vim editor, press i to enter insert mode. Locate and modify the following key parameters for your environment:

# Set the Nginx log directory path (default is for LNMP package; modify as needed)
log_files_path="/home/wwwlogs/"
# Logs will be stored in a "year/month/" directory structure with filename "originalname_YYYYMMDD.log"
log_files_dir=${log_files_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")
# Set log names to rotate (without .log suffix), separate multiple names with spaces
log_files_name=(access xxx.com)
# Set the Nginx executable path
nginx_sbin="/usr/local/nginx/sbin/nginx"
# Set the number of days to keep logs
save_days=30

After editing, press ESC to exit insert mode, then type :wq to save and quit vim.

Step 3: Configure the Crontab Scheduled Task

Run the following command to edit the current user's crontab:

crontab -e

Press i to enter insert mode and add the following line (e.g., to run daily at 5:00 AM):

00 05 * * * /bin/bash /root/cut_nginx_logs.sh

After adding the line, press ESC, then type :wq to save and exit.

Completion and Verification

The configuration is now complete. The system will automatically run the log rotation task daily at 05:00, archiving logs to the corresponding year/month/ directory and deleting logs older than save_days (default 30 days).

Note: Ensure the log_files_path and nginx_sbin paths in the script match your server's actual paths. After initial setup, it's recommended to run the script manually once to verify it works:

/bin/bash /root/cut_nginx_logs.sh
