获取按照ip进行统计，每个客户端ip的连接数。

[redis@lxd-vm1 ~]$ cat a | awk -F[\ \=\:] '{print $4}' | awk '{array[$0]++}END{for(i in array){print i,array[i]}}' | sort -nrk2 |column -t

（1）根据空格，等于号，分号，3个分隔符的第4列就是客户端ip，当然也可以多个awk分别获取。

（2）将获取到的每一行存在一个数组array中，下标是获取第一步获取的客户端ip，

（3）循环最后输出数组的元素和出现的次数，排序，格式化输出。

当然也可以使用sort和uniq的方式获取，这里主要是学习awk数组的使用。

[redis@lxd-vm1 ~]$ cat a | awk -F[\ \=\:] '{print $4}'|sort | uniq -c | sort -nrk1 |column -t
