Nginx CPU内存情况
短连接一旦-n 大于 10000 ，nginx 刚开始直接100%，但是redis-server 负载相对较小，以下是 -n = 40000
Requests per second: 1105.62 [#/sec] (mean)
第二次 -n = 40000 测试结果
Requests per second: 933.82 [#/sec] (mean)
总结：
使用短连接一开始nginx 负载就满载100% ，太可怕了，但是redis-server 负载相对较小，(30000--->100%) 、(20000--->90%)、(10000--->70~90%)，测试数据显示，安全最大连接在5000 以内

长连接-n = 2500000 ，nginx 刚开始不会超过50%，但是redis-server 负载相对高点，最高在50%左右，测试结果：

Nginx CPU内存情况
Completed 2000000 requests 请求截图
Completed 3500000 requests 请求截图 ，这时候的redis-server 负载保持在38%左右
测试到最后AB 压力直接爆掉
(-n---->nginx负载----->redis-server负载---->Requests per second)、
(100000--->37%--->37%---->28303.90) 表示很快完成
(200000--->50%--->56%--->33518.21)
(500000--->67%--->74%--->23959.52) redis-server 不稳定
(1000000--->50%--->50%--->23959.52) 2个都比较稳定，都能够保持在50%以下
总结：
使用长连接，10W 连接时毫无压力的，示，安全最大连接在20W 以内（测试环境可以100W没问题）
1、短连接Nginx负载太高 10000 链接负载直接飙到90+%
三、测试代码
