按日期截断分割nginx日志的脚本

由于公司网站很多，要是手动做nginx日志切割就会很繁杂，不如弄些shell脚本实现半自动处理。

首先，统一设置各站点的日志文件格式

# vi domain.sh

#!/bin/sh

sed -i '/access_log/d' /usr/local/nginx/vhost/*.conf

#### change path to /usr/local/nginx/vhost and use the command to get the DOMAIN_LIST : 
### ls -lh *.conf |awk '{print $9}'|sed 's/$/ \/' > domain.txt ####

DOMAIN_LIST=(
bbs.elecfans.com.conf 
cdnimg.xianbey.com.conf 
c.elecfans.com.conf 
......
common.qbaobei.com.conf 
elecfans.com.conf 
)

DOMAIN_ALL_LEN=${#DOMAIN_LIST}

i=0
while [ $i -lt $DOMAIN_ALL_LEN ]
do
  sed -i "/server_name/ a access_log logs/access.${DOMAIN_LIST[$i]}.log main;" /usr/local/nginx/vhost/${DOMAIN_LIST[$i]}
  let i++
done

接着测试下nginx的配置有没错误

# /etc/init.d/nginx test

## 如果没有错误就reload下nginx，有错那就检查配置吧 ##

# /etc/init.d/nginx reload

按日期轮循切割nginx日志

[root@]# vi Cut_nginx_error_log.sh

#!/bin/sh

## Cut Nginx Error Log ##

LOGS_PATH=/usr/local/nginx/logs
YESTERDAY=$(date -d "yesterday" +%Y-%m-%d)
mv ${LOGS_PATH}/error.log ${LOGS_PATH}/error_${YESTERDAY}.log
kill -USR1 $(cat /usr/local/nginx/logs/nginx.pid)

[root@]# vi Cut_nginx_log.sh

#!/bin/sh

## Cut Nginx Log ##

### use the follow command to get th ACCESS_LOG_LIST: 
### sed 's/conf/&.log/' domain.txt > log.txt
### sed 's/^/access.&/' log.txt >> ng_log.txt ###

LOGS_PATH=/usr/local/nginx/logs
YESTERDAY=`date -d "yesterday" +%Y-%m-%d`

ACCESS_LOG_LIST=(
access.log 
access.bbs.elecfans.com.conf.log 
access.cdnimg.xianbey.com.conf.log 
......
access.c.elecfans.com.conf.log 
access.common.qbaobei.com.conf.log 
access.elecfans.com.conf.log 
)

ACCESS_LOG_ALL_LEN=${#ACCESS_LOG_LIST}
i=0
while [ $i -lt $ACCESS_LOG_ALL_LEN ]
do
  mv ${LOGS_PATH}/${ACCESS_LOG_LIST[$i]} ${LOGS_PATH}/${ACCESS_LOG_LIST[$i]}.${YESTERDAY}.log
  let i++
done

kill -USR1 `cat /usr/local/nginx/logs/nginx.pid`

删除日志

[root@]# vi Del_nginx_log.sh

#!/bin/sh

#Delete Nginx Log
LOGS_PATH=/usr/local/nginx/logs

YESTERDAY=$(date -d "-3day" +%Y-%m-%d)
rm -rf ${LOGS_PATH}/access*.conf.log.${YESTERDAY}.log
rm -rf ${LOGS_PATH}/error_${YESTERDAY}.log

设置crontab定时任务

[root@]# crontab -e

00 00 * * * /bin/bash /usr/local/nginx/sbin/Cut_nginx_log.sh
00 00 * * * /bin/bash /usr/local/nginx/sbin/Cut_nginx_error_log.sh
00 18 * * * /bin/bash /usr/local/nginx/sbin/Del_nginx_log.sh

如此便可

PS：有不当之处望请各位友友指点
