公司新的需求，怀疑PV和IP的比例不对，看是不是有恶意的东东：
NGINX配置：
log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘ ‘$status $body_bytes_sent "$http_referer" ‘ ‘"$http_user_agent" "$http_x_cookie" "$request_time" "$upstream_response_time" "$upstream_cache_status" "$uid"‘;
set $uid "-"; if ( $http_cookie ~* "uid=(\S+)(;.*|$)"){ set $uid $1; }
PV前二十位排行榜：
cat test.log|sort|awk ‘$NF!~/-/ {print $1"," $NF}‘|uniq |awk -F , ‘{print $1}‘|uniq -c|sort -nr|head -20
12 53.27.4.22
1 61.183.86.163
1 61.183.237.146
1 58.255.215.115
1 27.154.152.131
1 223.240.50.192
1 222.94.205.228
1 219.140.69.67
1 218.89.115.155
1 218.28.77.119

1 124.117.198.63
1 122.224.216.242
1 121.61.112.2
公司总的IP数：
cat test.log|sort|awk ‘$NF!~/-/ {print $1"," $NF}‘|uniq |awk -F , ‘{print $1}‘|uniq -c|sort -nr|wc -l
32
公司总的UV数：
cat test.log|sort|awk ‘$NF!~/-/ {print $1"," $NF}‘|uniq |awk -F , ‘{print $1}‘|uniq -c|sort -nr|awk ‘BEGIN{total=0}{total=total+$1}END{print "UV is:" total}‘
UV is:43
