注意：ab test是不支持長鏈接壓測的，只支持短鏈接壓測web

ab性能不行，會拖累nginx回包和關閉連接的延遲，最終影響總體nginx併發測試，嘗試同時開多個ab發包（http://www.itzk.com/thread-583354-52-1.shtml）apache

單獨安裝ab和htpasswdcentos

yum install -y httpd-tools

完成後，就能夠直接運行ab


# which ab
/usr/bin/ab

# rpm -qf /usr/bin/ab
httpd-tools-2.2.15-47.el6.centos.1.x86_64

# which htpasswd
/usr/bin/htpasswd

壓測方法，必定要指定頁面名服務器

/usr/bin/ab  -n 3000 -c 3000 https://www.baidu.com/index.php

壓測以前先執行下面命令網絡

ulimit -n 65535

htpasswd加密併發

默認以DES加密
htpasswd -c /root/aa.txt  test
# cat aa.txt
test:Dl4dQa5GI3Qzs

md5和sha加密
htpasswd -c -m  /root/.aa.txt  user1

ab test

先查看一下版本信息 ab -V（注意是大寫的V）

二、咱們也可使用小寫的v查看下ab命令的一些屬性 ab -v

一、命令格式
ab命令放在apache目錄bin目錄下面，使用方法以下

./ab -n 3000 -c 3000 http://www.test.com/

其中-n表明每次併發量，-c表明總共發送的數量

二、測試結果分析
[root@Svr107 bin]# ./ab -n 3000 -c 3000 http://www.test.com/

三、若是用ab訪問的是本機上的web服務器，使用127.0.0.1或者是web服務器上的網卡IP地址，這個是不走網絡設備的，能夠忽略網絡消耗

四、ab使用的一些問題
a、ab命令在通常系統上面作測試時候，通常併發不能超過1024個，實際上是由於由於系統限制每一個進程打開的最大文件數爲1024，能夠用ulimit -a來查看
open files (-n) 65536 ##這個我係統已經修改過
b、-n 能夠指定最大請求數，可是不能超過50000個
c、-v n 當n>=2 時，能夠顯示發送的http請求頭，和響應的http頭及內容,壓力測試時不要這麼作
[root@Svr107 bin]# ./ab -n 1 -c 1 -v 2 http://www.test.com/

在作壓力測試的時候，通常狀況下壓力測試客戶端接收到的數據量必定會遠大於發送出去的數據量

socket: Too many open files (24)

解決方法：

查看當前要以打開的文件個數

[root@zabbix ~]# ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 14802
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024    #只能打開1024個socket文件 /端口

virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

調整能夠打開的文件數

[root@zabbix ~]# ulimit -n 65535
從新執行ab命令便可解決
