问题 It's weird issue, zeus start running smoothly. rspec spec/ does it's job flawless. My spec_helper config is # encoding: UTF-8 require 'rubygems' # This file is copied to spec/ when you run 'rails generate rspec:install' ENV["RAILS_ENV"] ||= 'test' require File.expand_path("../../config/environment", __FILE__) require 'rspec/rails' require 'email_spec' require 'rspec/autorun' require 'capybara/rspec' require 'shoulda-matchers' require 'shoulda/matchers/integrations/rspec' Dir["./spec/support/*

阅读更多关于某个应用的CPU使用率居然达到100%，我该怎么办？

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 本文是通过学习极客时间专栏《Linux性能优化实战》05 | 基础篇：某个应用的CPU使用率居然达到100%，我该怎么办？ CPU 使用率为了维护 CPU 时间，Linux 通过事先定义的节拍率（内核中表示为 HZ），触发时间中断，并使用全局变量 Jiffies 记录了开机以来的节拍数。每发生一次时间中断，Jiffies 的值就加 1。节拍率 HZ 是内核的可配选项，可以设置为 100、250、1000 等。不同的系统可能设置不同数值，你可以通过查询 /boot/config 内核选项来查看它的配置值。比如在我的系统中，节拍率设置成了 250，也就是每秒钟触发 250 次时间中断。 $ grep 'CONFIG_HZ=' /boot/config-$(uname -r) CONFIG_HZ=250 同时，正因为节拍率 HZ 是内核选项，所以用户空间程序并不能直接访问。为了方便用户空间程序，内核还提供了一个用户空间节拍率 USER_HZ，它总是固定为 100，也就是 1/100 秒。这样，用户空间程序并不需要关心内核中 HZ 被设置成了多少，因为它看到的总是固定值 USER_HZ。 Linux 通过 /proc 虚拟文件系统，向用户空间提供了系统内部状态的信息，而 /proc/stat 提供的就是系统的

Zeus Rewrite Rules

问题 I have a website that renders the URL: /work.php?cat=identity Normally I would research how to use mod_rewrite but unfortunately my hosting (Namesco) uses Zeus and not Apache, which is strange. How would I use Zeus' rewrite rules to convert to: /work/identity This is a much cleaner, nicer SEO friendly version. On top of this, I still need the $_GET variable to be active because it requests information about the variable cat from the database. I've never rewritten URLs before so I've no idea

问题 In my Rails 3.2.13 app, I'm using Zeus. In the test environment I use PostgreSQL. When I run Cucumber and then RSpec (or the other way around), 9 out of 10 times I get the message: PG::Error: ERROR: database "bp_test" is being accessed by other users DETAIL: There are 1 other session(s) using the database. : DROP DATABASE IF EXISTS "bp_test" Tasks: TOP => db:test:load => db:test:purge (See full trace by running task with --trace) It takes a whole non-deterministic circus of trying to kill

Apache自带的ab压力测试工具用法详解

阅读更多关于 Apache自带的ab压力测试工具用法详解

ab命令原理 Apache的ab命令模拟多线程并发请求，测试服务器负载压力，也可以测试nginx、lighthttp、IIS等其它Web服务器的压力。 ab命令对发出负载的计算机要求很低，既不会占用很多CPU，也不会占用太多的内存，但却会给目标服务器造成巨大的负载，因此是某些DDOS攻击之必备良药，老少皆宜。自己使用也须谨慎。否则一次上太多的负载，造成目标服务器直接因内存耗光死机，而不得不硬重启，得不偿失下载安装： http://mirror.bit.edu.cn/apache//httpd/binaries/win32/?C=M;O=A 找到 httpd-2.2.21-win32-x86-no_ssl.msi windows版本官方只提供源码，这里可参考下载：链接： https://pan.baidu.com/s/1ylrI7G5nSFu-LBlYgY0T3Q 提取码：uzmr 运行：在Windows系统下，打开cmd命令行窗口，定位到apache安装目录的bin目录下 cd C:\Program Files (x86)\Apache Software Foundation\Apache2.2\bin 键入命令： ab -n 800 -c 800 http://192.168.0.10/ （-n发出800个请求，-c模拟800并发，相当800人同时访问，后面是测试url）

问题 I'm about to go live with a Codeigniter powered site. I want to remove index.php from the url so that instead of this: http://www.mysite.com/index.php/controller I get something like this: http://www.mysite.com/controller So far, pretty straightforward. In the past I've used the mod-rewrite rule supplied by the Codeigniter documentation: RewriteEngine on RewriteCond $1 !^(index\.php|images|robots\.txt) RewriteRule ^(.*)$ /index.php/$1 [L] This works like a charm. However, for this site, I'm
