openwrt 安装swoole

112 阅读 0 评论
我是靠谱客的博主 深情山水，最近开发中收集的这篇文章主要介绍openwrt 安装swoole，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

本人所写的博客都为开发之中遇到问题记录的随笔，主要是给自己积累些问题。免日后无印象，如有不当之处敬请指正(欢迎进扣群 24849632 探讨问题）；

打算在在openwrt下安装PHP扩展swoole，下面记录相关的过程：

swoole在PECL地址为：http://pecl.php.net/package/swoole

先下载最新的软件包swoole-4.4.16.tgz ，并移动openwrt/dl目录下

root# cd openwrt

root# mkdir -p package/utils/php7

root# cp feeds/packages/lang/php7-pecl-redis/ package/utils/php7/php7-pecl-swoole -rf

root# sha256sum dl/swoole-4.4.16.tgz

root# vim package/utils/php7/php7-pecl-swoole/Makefile

解决办法：

这个问题，我尝试解决花了两天的时间，通过查看Makefile，发现是因为openwrt在BulidPackage时会将所有的“+”号正则为空字符，因此最后添加的依赖变成了libstdc, 导致在打包为IPK时不成功，修改相应的依赖信息为libstdcpp，成功完成编译

欣喜之时，赶紧将生成的镜像写入了开发板并创建了相应的测试程序

<?php
	//高性能HTTP服务器
    $http = new SwooleHttpServer("0.0.0.0", 9501);

    $http->on("start", function ($server) {
        echo "Swoole http server is started at http://127.0.0.1:9501n";
    });

    $http->on("request", function ($request, $response) {
        $response->header("Content-Type", "text/plain");
        $response->end("Hello Worldn");
    });

    $http->start();

赶紧运行， 

Swoole信息

什么鬼？？

在swoole群内发布了相关的问题，得到了swoole开发者韩天峰的耐心指导，综合判断为OpenWRT使用的C库为uLibc, 不包含ucontext， 并解释了实现协程的三种实现方式

1： boost context asm ，

2： glibc ucontext，

3： c++11 thread

因为glibc内置的协程函数uclibc内并不存在，因此大韩分别给出了另二个实现方案的解决办法，分别是：

1，修改config.h, 在config.h中定义SW_USE_THREAD_CONTEXT 宏（此方法对应C++11 thread)

#define SW_USE_THREAD_CONTEXT 1

此方法经测试无效，故只能测试第一种方法，使用boost context asm方法； 

2，修改config.m4文件， c启用 boost asm （此方法对应boost context asm)

    elif test "$SW_CPU" = "mips32"; then
        if test "$SW_OS" = "LINUX"; then
           SW_CONTEXT_ASM_FILE="mips32_o32_elf_gas.S"
        else
            SW_USE_ASM_CONTEXT="no"
        fi
    else
        SW_USE_ASM_CONTEXT="no"
    fi

这种方式其实已经实现了，有可能是在OpenWRT平台下，CPU这识别错误导致无法加载协程实现文件造成的，相关的情况需要进一步确认Makefile的信息。 

检查后发现在swoole的config.m4文件中没有判断mipsel簇CPU的方法（己向swoole提交PR），修改如下（L554)：

    AS_CASE([$host_cpu],
      [x86_64*], [SW_CPU="x86_64"],
      [x86*], [SW_CPU="x86"],
      [i?86*], [SW_CPU="x86"],
      [arm*], [SW_CPU="arm"],
      [aarch64*], [SW_CPU="arm64"],
      [arm64*], [SW_CPU="arm64"],
      [mips*], [SW_CPU="mips32"],
      [
        SW_USE_ASM_CONTEXT="no"
      ]
    )

在这个Case内增加了mips簇的检测分支，并将工程移出feeds目录，重新在menuconfig中选中并编译

这又是什么情况？？引入的ASM文件无法编译吗？直接CD到swoole的目录，使用宿主机编译，成功且汇编文件夹内也生成了中间文件lo, 仔细看了下错误，原来是用了GCC编译器，那只能改AS汇编器看看能怎么样，但PHPIZE生成的autoconf怎么修改编译器呢？经过查看生成的相关文件，信息将线索引入到了php目录文件夹，那么先修改下php.m4文件，再试一下

root#  vim php.m4

dnl Adds variable with it's value into Makefile, e.g.:
dnl AS = as
dnl

在第206行的位置增加  b_s_pre=$shared_s_pre,  b_s_pre=$php_s_pre 两个变量定义

dnl
dnl PHP_BUILD_SHARED
dnl
AC_DEFUN([PHP_BUILD_SHARED],[

swoole组件已经成功运行，但申请的内存过多，造成进程被Kernel Kill掉了，需要再修改测试文件的配置测试

Corun(function () {
    $server = new CoHttpServer("0.0.0.0", 9501, false);
    $server->handle('/', function ($request, $response) {
        $response->end("<h1>Index</h1>");
    });
    $server->handle('/test', function ($request, $response) {
        $response->end("<h1>Test</h1>");
    });
    $server->handle('/stop', function ($request, $response) use ($server) {
        $response->end("<h1>Stop</h1>");
        $server->shutdown();
    });
    $server->start();
});

重新在在开发板内运行，并使用浏览器打开

很好，一切正常！
