shell编写动态页面，听起来好搞笑，确实 实现起来也很搞笑。举个例子我想通过web页面展示我网站每小时的pv数 以及500错，当然统计pv数和500错 这要统计前台的nginx访问日志来得到。
答题思路
因为我们前台有4台nginx，我要首先合并每小时的4台nginx日志，统计出pv数和500错，然后把值传到我的web服务本机，具体脚本如下。
一.nginx日志合并所在服务器上编写脚本如下
#!/bin/bash
time=`date +%Y%m%d%H -d "-1 hour"`
rsync -av 192.168.0.20::logs/access.log.$time /backup/nginxlog/20/
rsync -av 192.168.0.149::logs/access.log.$time /backup/nginxlog/149/
rsync -av 192.168.0.148::logs/access.log.$time /backup/nginxlog/148/
rsync -av 192.168.0.48::logs/access.log.$time /backup/nginxlog/48/
cd /backup/nginxlog
logs=`find ./ -name access.log.$time`
cat $logs > /backup/nginxlog/agghour/access.log.$time.temp
grep jwml /backup/nginxlog/agghour/access.log.$time.temp|wc -l>/opt/yanchao/huoqupv.txt
awk '$9~/500/{print}' /backup/nginxlog/agghour/access.log.$time.temp|wc -l>/opt/yanchao/huoqu500.txt
awk '{++a[$1]}END{for ( i in a )print i,a[i]}' /backup/nginxlog/agghour/access.log.$time.temp|sort -k2 -rn |head -n10|awk '{print $1}'>/opt/yanchao/tongji.txt
awk '{++a[$1]}END{for ( i in a )print i,a[i]}' /backup/nginxlog/agghour/access.log.$time.temp|sort -k2 -rn |head -n10|awk '{print $2}'>/opt/yanchao/cishu.txt
cat /backup/nginxlog/agghour/access.log.$time.temp |sort -k 4 > /backup/nginxlog/agghour/access.log.$time
rm -f /backup/nginxlog/agghour/access.log.$time.temp
rm -f /backup/nginxlog/20/* && rm -f /backup/nginxlog/149/* && rm -f /backup/nginxlog/148/* && rm -f /backup/nginxlog/48/*
二.在web服务器上起个80端口
在web根目录新建index.html
Time |
Count PV |
500error |
|---|
新建index1.html
<\tr>
|
编写脚本如下
#!/bin/bash
rm -f /var/www/html/index1.html
cp /var/www/html/index2.html /var/www/html/index1.html
rm -f /var/www/html/test.txt
c=`cat /opt/yanchao/pv.txt`
a=`date +%H:00 -d '-1 hour'`
b=`date +%H:00`
g=`cat /opt/yanchao/500.txt`
echo -e "$a-$b\t$c\t$g\t" >/var/www/html/test1.txt
e=($(awk '{print $1}' /var/www/html/test1.txt))
f=($(awk '{print $2}' /var/www/html/test1.txt))
d=($(awk '{print $3}' /var/www/html/test1.txt))
for ((i=0;i<=${#e[@]};i++))
do
echo "
