篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了linux中http启动时502 bad getway相关的知识，希望对你有一定的参考价值。
参考技术A 希望对你有帮助： 通俗解释一下 1.什么是502 bad getway 报错 简单来说 502 是报错类型代码 bad getway 错误的网关 2.产生错误的原因 连接超时 我们向服务器器发送请求 由于服务器当前链接太多，导致服务器方面无法给于正常的响应,产生此类报错 ... 参考技术B 看下错误日志文件/var/log/httpd/error.log
一般是配置文件httpd.conf有误导致的，修改或者注释相应的。
开始运行应用程序时 EXC_BAD_ACCESS 崩溃？
【中文标题】开始运行应用程序时 EXC_BAD_ACCESS 崩溃？【英文标题】：EXC_BAD_ACCESS crash when start running app? 【发布时间】：2017-12-02 19:21:41 【问题描述】：我在我的应用程序中使用 linphone SDK。当我开始运行应用程序崩溃立即发生。
应用启动后调用[Fastaddreesbook init] 调用[FastAddreesBook reload] 调用[FastAddreesBook loadData] 调用[FastAddreesBook normalizeSipURI] 和 exc_bad_access 在此方法中发生崩溃：
LinphoneAddress* linphoneAddress = linphone_core_interpret_url([LinphoneManager getLc], [address UTF8String]);
线程 1：EXC_BAD_ACCESS（代码=1，地址=0x0）

附注：
-我使用非arc项目
-zombie 也启用了，但没有任何改变。
-Ivalue 是意志，那是因为崩溃发生了。
调试控制台： 警告：无法在进程中执行支持代码来读取 Objective-C 类数据。这可能会降低可用类型信息的质量。
【问题讨论】：
这是我朋友的基本调试。您正在尝试访问 0 指针。单步调试代码，看看为什么它是 0 并修复它。 【参考方案1】：LinphoneAddress* linphoneAddress = linphone_core_interpret_url([LinphoneManager getLc], [address UTF8String]);
address 为零。弄清楚为什么会这样，你就有了崩溃源。它可能应该为 nil，因为它可能是原始记录中的可选字段。
那个代码有点乱，顺便说一句。它不遵循标准模式（例如，许多以get 为前缀的方法）。它确实应该进行现代化改造并启用 ARC。
【讨论】：
（IValue 为 nil 但 IDict 有值。）这一行返回 nil 但我不知道为什么？ CFStringRef lValue = CFDictionaryGetValue(lDict, kABPersonInstantMessageUsernameKey); 因为该键没有任何价值。用户没有即时消息用户名。 为什么代码在模拟器中正常，但在真实设备中不起作用。可能是内存问题。 @MehdiNegahban 问题很简单；用户没有即时消息用户名。弄清楚。其他一切都是一种干扰。以上是关于linux中http启动时502 bad getway的主要内容，如果未能解决你的问题，请参考以下文章
