Linux系统查询nginx或apache当天访问最多的IP方法，例子命令：
cat /alidata/log/nginx/access/ip.log |grep `date "+%d/%b"`|awk '{print $1}'|sort |uniq -c |sort -rn
注意：其中 /alidata/log/nginx/access/ip.log 部分需要替换为实际的路径和文件。
SQL语句执行错误：SELECT * FROM emlog_sort where pid= ORDER BY sid ASC, taxis asc
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ORDER BY sid ASC, taxis asc' at line 1
