openstack性能测试器(3):移植rabbitmq-c

发表于   |   分类于   |  

rabbitmq

rabbitmq是AMQP的一个具体实现。与之类似的还有apache的qpid。rabbitmq的官网是http://www.rabbitmq.com/

我要做的是一个收发消息的模拟器，那么就用client就可以了。rabbitmq提供了各种语言的client版本，其中JAVA、C#、ErLang是官方维护的亲儿子版本。至于C语言的版本，则被归类到了other languages，下载链接是http://www.rabbitmq.com/devtools.html，C版本的链接是https://github.com/alanxz/rabbitmq-c

移植

编译rabbitmq-c

生产环境用的是suse，那边哥们给我的测试环境无法mount到我的本机，所以，只能在我docker ubuntu14.04来先验证一下。

git clone git@github.com:alanxz/rabbitmq-c.git
cd rabbitmq-c
mkdir build && cd build
cmake ..
cmake --build . --config BUILD_TOOLS=OFF

cmake ..时会提示找不到xmlto等等，因为我不需要生成辅助工具（文档、命令行工具等等)，暂时不管它。
BUILD_TOOLS=OFF就表示不生成辅助工具

一路编译没有报错，至此，我们的rabbitmq就编译成功了，接下来就是要把librabbitmq移植到现有代码中。

移植过程

  • 拷贝librabbitmq到原有代码中
  • 在makefile里加上librabbitmq的路径
  • make，提示说找不到amqp_framing.h，原因是include用的是<>，而amqp_framing.h就在同一个目录。
  • sed -i s/<amqp_framing.h>/\”amqp_framing.h\”/g改成相对路径，再次make，不报这个错了。
  • 找不到threads.h，原因是没有把librabbitmq/unix-I，所以需要改以下路径为unix/threads.h

  • 找不到AMQP_PLATFORM,这个是在config.h里定义的。看了下报错的c文件，确实有include了config.h，但为什么还报这个错呢？

    #ifdef HAVE_CONFIG_H
    #include "config.h"
    #endif

  • 原因就在于HAVE_CONFIG_H了，在makefile的gcc后加上-DHAVE_CONFIG_H，再次编译，就OK了。

在ubuntu上已经搞定，接下来就是迁移到suse上。
关键点就在于config.h，因为config.h包含了内核版本以及epoll等等，所以需要在suse上编译一下rabbitmq-c，然后把suse上的config.h替换ubuntu上的config.h，编译就OK了。
