Nginx日志分割与Nginx日志分析脚本(很实用)
vi /root/cutlog.sh#!/bin/bash
I=`ps aux | grep nginx | grep root | grep -v 'grep nginx' | awk '{print $14}'` #查找nginx进程
if [ $I == /usr/local/nginx/sbin/nginx ];then
ACCLOG=`cat /usr/local/nginx/conf/nginx.conf | grep' access_log' | awk '{print $2}'`#如果nginx进程在，就找到配置文件，读取accesslog路径
ERRLOG=`cat /usr/local/nginx/conf/nginx.conf| grep^error| awk '{print $2}'| cut-d";" -f1`#错误日志的路径
ls $ACCLOG #查看是否有此文件
if [ $? -eq 0 ];then #如果有
mv $ACCLOG$ACCLOG.`date -d "-1 day" +%F`#重命名当前日志
mv $ERRLOG $ERRLOG.`date -d "-1 day" +%F`
touch $ACCLOG #创建空日志
touch $ERRLOG
chown nginx:root$ACCLOG #修改属主
chown nginx:root$ERRLOG
[ -f /usr/local/nginx/logs/nginx.pid ] && kill -USR1 `cat /usr/local/nginx/logs/nginx.pid` #判断进程，并重新加载（这里的kill -USR1会使nginx将新产生的日志写到刚创建的新日志里面。）
/mnt/logs/checklog.sh $ACCLOG.`date "-1 day" +%F` #这个是日志分析脚本
gzip $ACCLOG.`date -d "-1 day" +%F`#压缩日志
gzip $ERRLOG.`date -d "-1 day" +%F`
mv$ACCLOG.`date -d "-10 day" +%F`.*/mnt/history.nginx.log/ #将10天前的老日志清理到其他地方，（你们如果想删除的可以自己改成删除）
mv$ERRLOG.`date -d "-10 day" +%F`.*/mnt/history.nginx.log/

nginx日志分析脚本：
vi /mnt/logs/checklog.sh
#!/bin/bash
echo -e"####################`date +%F`" >> /mnt/logs/400.txt
echo -e"####################`date +%F`" >> /mnt/logs/URL.txt

cat $1 | wc -l >> /mnt/logs/IP.txt #分析IP

cat $1 |awk '{print $1}' |sort | uniq -c| sort -rn | head -n20>> /mnt/logs/IP.txt
N=`cat /mnt/logs/CODE.txt | wc -l`
for I in $(seq 1 $N)

if [ $M -ge 400 ]
then
echo "#####FIND $M###############">>/mnt/logs/400.txt #分析错误请求
