Linux定期清理nginx 日志

为了在Linux系统上定期清理Nginx日志，可以使用cron定时任务来自动执行日志清理脚本。以下是详细步骤：

1. 创建日志清理脚本

首先，创建一个脚本，用于归档和清理旧的Nginx日志。例如，将其命名为

/usr/local/bin/cleanup_nginx_logs.sh

#!/bin/bash

# Directory where Nginx logs are stored
LOG_DIR="/var/log/nginx"
# Number of days to keep logs
DAYS_TO_KEEP=30
# Archive directory
ARCHIVE_DIR="/var/log/nginx/archive"

# Create archive directory if it doesn't exist
mkdir -p $ARCHIVE_DIR

# Find and move old log files to the archive directory
find $LOG_DIR -type f -name '*.log' -mtime +$DAYS_TO_KEEP -exec mv {} $ARCHIVE_DIR \;

# Compress archived logs
find $ARCHIVE_DIR -type f -name '*.log' -exec gzip {} \;

# Remove compressed logs older than DAYS_TO_KEEP
find $ARCHIVE_DIR -type f -name '*.gz' -mtime +$DAYS_TO_KEEP -exec rm {} \;

# Reload Nginx to reopen log files
systemctl reload nginx

2. 赋予脚本执行
