nginx 根据url访问次数限制

#获取日期
date=`date +"%y%m%d"`
#设置日志路径
data="/data/logs/abc.com/access.log"
#配置文件路径
conf="/usr/local/nginx/conf/selfconf/abc.conf"
#设置要监控的地址,多个地址用空格隔开，监控全局设为null
url='/pub/send/yzm/'
#白名单IP
Whitelist="1.1.1.1|2.2.2.2"
#过滤不计次错误返回值
error_num="403|503"
#最大次数
maxnum=100

#判断日志是否为空
if [ -s "$data" ];
then
    #将每分钟的日志转存到每日日志里去
    cat $data >> $data$date


    #获取要禁的ip
    for aurl in $url;
    do
        #判断是否有设置监控地址，否则全局监控
        if [[ "$url"x == "null"x ]];
