nginx日志切割脚本分享-巨人网络通讯

实现方法一

#!/bin/bash
Logs_path="/data/Application/nginx/logs"
Pid_path="/data/Application/nginx/nginx.pid"
Month=`date +%Y-%m`
Date=`date +%Y-%m-%d`
Time=`date +%H`
WaitTime=$((24*60*60))

LogCut()
{
  cd $Logs_path
  mkdir -p $Month
  while true
  do
    mv $Logs_path/access.log $Logs_path/$Month/access_$Date.log
    kill -USR1 `cat ${Pid_path}`
  done
  sleep $WaitTime
  return 0
}

case $1 in
start)
    LogCut >/dev/null 
    ;;
stop)
    kill -9 `ps aux | grep LogCut | grep -v grep | awk '{print $2}'`>/dev/null
    ;;
restart)
    kill -9 `ps aux | grep LogCut | grep -v grep | awk '{print $2}'`>/dev/null
    LogCut >/dev/null 
    ;;
*)
    echo "Usage ERROR!Please use "start" or "stop" or "restart"!"
esac

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
