实现方法二

试验环境：

# cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.3 (Tikanga) # /opt/nginx/nginx -v nginx version: nginx/1.6.2

代码：

#!/bin/bash # ============================================================================== # chmod u+x /opt/nginx/cut_nginx_log.sh # crontab -e # 0 0 * * * /opt/nginx/cut_nginx_log.sh > /opt/nginx/logs/cut_nginx_log.log 2>&1 # ============================================================================== LOGS_PATH="/opt/nginx/logs" ARCHIVE_YEAR=$(date -d "yesterday" "+%Y") ARCHIVE_MONTH=$(date -d "yesterday" "+%m") ARCHIVE_DATE=$(date -d "yesterday" "+%Y%m%d_%H%M%S") if [ -r /opt/nginx/nginx.pid ]; then mkdir -p "${LOGS_PATH}/${ARCHIVE_YEAR}/${ARCHIVE_MONTH}" mv "${LOGS_PATH}/access.log" "${LOGS_PATH}/${ARCHIVE_YEAR}/${ARCHIVE_MONTH}/access_${ARCHIVE_DATE}.log" kill -USR1 $(cat "/opt/nginx/nginx.pid") sleep 1 gzip "${LOGS_PATH}/${ARCHIVE_YEAR}/${ARCHIVE_MONTH}/access_${ARCHIVE_DATE}.log" else echo "Nginx might be down" fi # ============================================================================== # Clean up log files older than 100 days # ============================================================================== # Change HOUSEKEEPING=1 to enable clean up HOUSEKEEPING=0 KEEP_DAYS=100 if [ $HOUSEKEEPING == 1 ]; then if [ -d "${LOGS_PATH}" ]; then find "${LOGS_PATH}" -type f -name "access_*.log.gz" -mtime +${KEEP_DAYS} -exec rm -f {} ; fi fi
