使用shell测试cdn状态

　　公司使用多家cdn，测试cdn在各个地方的响应情况，以便于提高视频访问的用户体验。分别在阿里云华南1，华东1，华东2，华北2等不同地区节点测试。该随笔为自己所用。

 

1.该脚本会测试某一cdn的url，如果302，继续测试，如果是503，则测试cdn源站是否也为503，并记http_code，录测试时间以及测试的url等信息。

#!/bin/bash

#set -e
start_time=$(date +%s)
today=$(date +%F)
mkdir -pv  /cdn/logs &> /dev/null
dl200="/cdn/logs/dl200-$today.log"
dlno200="/cdn/logs/dlno200-$today.log"
> $dl200
> $dlno200
#echo $dl200 $dlno200
#exit
cat /cdn/shell/dltxt/dl-$today |while read line
do
  #echo $line
  HTTP_CODE=$(curl -XGET  -I -m  -o /dev/null -s -w "%{http_code}""\n" $line)
  if [ "$HTTP_CODE" -eq  ];then
    CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
    echo  $HTTP_CODE $CURRENT_TIME $line >> $dl200
  elif [ "$HTTP_CODE" -eq  ];then
    HTTP_NEW_CODE=
    NEW_URL=$(curl -XGET  -I -m  -s  $line |grep ^Location|awk -F" " '{print $2}'|tr -d '\r'|tr -d '$')
    while [ "$HTTP_NEW_CODE" -eq  ]
    do
      #echo $NEW_URL
      HTTP_NEW_CODE=$(curl -XGET -I -m  -o /dev/null -s -w "%{http_code}""\n" $NEW_URL)
      #echo $HTTP_NEW_CODE
      #if [ "$HTTP_NEW_CODE" -eq 200 ];then
      #  echo $HTTP_NEW_CODE $NEW_RUL >> /xiaoke/shell/logs/gs200.log
      if [ "$HTTP_NEW_CODE" -eq  ];then
        NEW_URL=$(curl -XGET  -I -m  -s  $NEW_URL |grep ^Location|awk -F" " '{print $2}'|tr -d '\r'|tr -d '$')
      elif [ "$HTTP_NEW_CODE" -eq  ];then
        CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
        echo $HTTP_NEW_CODE $CURRENT_TIME $NEW_URL >> $dl200
      elif [ "$HTTP_NEW_CODE" -eq  ];then
        CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
        echo $HTTP_NEW_CODE $CURRENT_TIME $NEW_URL >> $dlno200
        SOURCE_URL=$(echo $line |sed 's;gxbvideo-dl;gxbvideo;g')
        SOURCE_CODE=$(curl -XGET -I -m  -o /dev/null -s -w "%{http_code}""\n" $SOURCE_URL)
        if [ "$SOURCE_CODE" -eq  ];then
          echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
        else
          echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
        fi
      else
        CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
        echo $HTTP_NEW_CODE $CURRENT_TIME $NEW_URL >> $dlno200
      fi
    done
  elif [ "$HTTP_CODE" -eq  ];then
    CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
    echo $HTTP_CODE $CURRENT_TIME $line >> $dlno200
    SOURCE_URL=$(echo $line |sed 's;gxbvideo-dl;gxbvideo;g')
    SOURCE_CODE=$(curl -XGET -I -m  -o /dev/null -s -w "%{http_code}""\n" $SOURCE_URL)
    if [ "$SOURCE_CODE" -eq  ];then
      echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
    else
      echo $SOURCE_CODE $CURRENT_TIME $SOURCE_URL >> $dlno200
    fi
  else
    #current_time=$(date '+%Y%m%d %H:%M:%S')
    CURRENT_TIME=$(date '+%Y%m%d %H:%M:%S')
    echo $HTTP_CODE $CURRENT_TIME $line >> $dlno200
  fi
sleep
done
end_time=$(date +%s)
#echo $end_time
delta_time=`expr $end_time - $start_time`
echo "总耗时:$delta_time秒" >> $dl200

2.查看测试信息日志即可。
