centos7下ab测试（Apache Bench）的相关文章

PHP性能：序——谈ab（Apache Bench）压力测试工具

PHP性能:序--谈ab(Apache Bench)压力测试工具 ab(Apache  Bench)是啥? ab是Apache自带的一个压力测试软件,可以通过ab命令和选项对某个URL进行压力测试.ab建议在linux环境下使用. 为啥要压力测试工具? 因为你不给你的网站压力,你不知道项目的最大的容量是多少,自己的知识有多少.在一定范围里,压力达到一定程度,动力和容量也就达到顶峰.所以说没有最大的容量,只有极致的性能优化. 压力测试工具,另一方面也为测试提供一个标准,为当前需要优化提供基础数据.

后端开发都应该了解点接口的压力测试(Apache Bench版)

背景 小A:小B,最近调你的接口老是超时呀,8秒都还没返回结果,是不是有性能问题呀! 小B :我看看~~ 类似这样的对话,在现实中是时有发生的,不是特别严重的话,往往大家也不会去重视这个事. 尤其是在一些测试资源并不完备的,开发人员对性能测试没有接触过的一些公司,遇到这些会显得更加力不从心. 本着对自己写出来的东西负责,上线之前,我们都应该对自己的接口进行一个简单的压力测试. 其实做这一步也是为了让我们心里有个度,有个底,不至于说连能承受多少量都不知道.如果什么都不知道,那很容易陷入一个无底深渊

unbuntu 下ab 测试工具的安装使用

Apache Benchmark(ab) 一款由apache提供的压力测试软件 首先我们先安装 环境 sudo apt-get install apache2-utils //使用 用法:ab [options][http[s]://]hostname[:port]/path //  -n 请求数 -c 并发数 url 目标压测地址 ab -n100 -c10  //对百度进行 压力测试 This is ApacheBench, Version 2.3 <$Revision: 1528965 $

centos7下，解决Apache错误日志文件过大问题

1,日志文件太大问题 第一步:停止Apache服务的所有进程,删除 /var/log/httpd目录下的 error.log.access.log文件 第二步:打开 /etc/httpd/conf 的 httpd.conf配置文件 并找到下面配置 ErrorLog logs/error.log 把上面的注释掉,换成 # 每天生成一个错误日志文件 ErrorLog "|/usr/sbin/rotatelogs /var/log/httpd/error_log%Y%m%d.log 86400 480

CentOS7下fail2ban配合apache

官网地址:http://www.fail2ban.org/wiki/index.php/Main_Page download fail2ban-0.10.tar.gz,然后rz到服务器, tar -xvf fail2ban-0.10.tar.gz 进入解压后的目录,查看README [[email protected] tmp]# cd fail2ban-0.10/ [[email protected] fail2ban-0.10]# cat README.md #查看python版本是否满足

apache压力测试工具的apache bench和JMeter的安装

Apache压力测试工具的安装 1,apache bench的安装 apache  bench工具集成在http的软件包内,可以直接安装apache就可以. 当有些时候,我们不需要用到所有的软件包,我们只需要安装安装其中的某个组件就可以, 例如apache  bench这个组件. 首先安装ab运行需要的软件包apr-util yum install apr-util 然后安装一个yum的工具包,为了可以单独弄出来ab 新建一个目录  mkdir /test 切换目录  cd /test yumd

利用Apache Bench进行压力测试（安装篇）

前言 API性能测试是企业级开发中非常重要的一环,API性能测试个人总结起来比较关注的两个点为: API在并发下是否会产生数据异常,比如秒杀系统的超买超卖 API极限情况下的QPS/TPS 目前比较流行的性能测试工具有LoaderRunner.Apache Bench.JMeter等,个人针对这三款性能测试工具都使用了一下,使用的感觉是: LoaderRunner是功能最强大的,压力测试后的各种报告什么都有,但是商用版本装一下时间比较长也比较麻烦,也有一定学习成本,上手用熟练需要一定时间 JMe
