1.编写bash脚本

#!/bin/bash  
step=1 #间隔的秒数,不能大于60  

host_list=("localhost" "192.168.75.137" "master1" "wugenqiang.master")
while [ 1 ]
do
    num=$(((RANDOM%7)+1))
    seq=$(((RANDOM%4)))
    url="http://"${host_list[$seq]}"/"$num".html";
    echo " `date +%Y-%m-%d\ %H:%M:%S` get $url"

    #curl http://192.168.75.137/1.html #调用链接
    curl -s $url > /dev/null

    sleep $step
done

2.演示操作结果展示

[root@master1 conf]# vim test_log_records_add.sh 
[root@master1 conf]# ./test_log_records_add.sh
