给PHP安装amqp扩展
有史以来最坑爹的一次扩展安装,不晓得诸位有没有尝试过…………各种报错啊!有木有?!¥#@%%&*……
捣鼓半天,只编译了个0.1.x的扩展版本,瞅了下,擦,函数少的可怜啊- -|||
不行,继续~
经过一天的努力,老天总算开眼了,赶紧总结下吧~
----------------------------------------------- 我是分割线 ---------------------------------------------------
AMQP――高级消息队列协议,目前比较有名气的实现大概就是大名鼎鼎的RabbitMQ了。
(不了解的童鞋先看下我这篇转载吧:《[RabbitMQ+Python入门经典] 兔子和兔子窝》)
PHP扩展当然还是官方推荐的好了。OK,就它了 http://php.net/manual/en/book.amqp.php
To install the AMQP PHP extension, you must first install the ? librabbitmq library. You will need the 0-9-1 version of the rabbitmq-c client library, linked to the rabbitmq-codegen version that corresponds to the version of the broker you are using. Use the following steps to download and install the library:
# Download the rabbitmq-c library @ version 0-9-1
hg clone http://hg.rabbitmq.com/rabbitmq-c/rev/b01825ecc112 rabbitmq-c
cd rabbitmq-c
# Add the codegen requirement. To find the full list, go here: http://hg.rabbitmq.com/rabbitmq-codegen/tags
# and copy the URL for the appropriate broker version.
hg clone http://hg.rabbitmq.com/rabbitmq-codegen/rev/16bbcb711380 codegen
# Configure, compile and install
autoreconf -i && ./configure && make && sudo make install
扩展是C写的,由于C与RabbitMQ通信一般需要依赖rabbitmq-c库(也就是librabbitmq),所以编译扩展前需要先装依赖库。好吧,那就按要求装吧~
原文是用hg工具,需要装mercurial(一个轻量级的版本控制系统),这里就不介绍了,我们还是用传统的方法。
首先,到这里下载rabbitmq-c的v0.2版:https://github.com/alanxz/rabbitmq-c/tags OR 直接shell:
wget https://github.com/alanxz/rabbitmq-c/tarball/0.2
tar zxvf 0.2
cd alanxz-rabbitmq*
(为什么0.2版?好吧,我也不知道,总之它的各版本兼容性非常不好,经过我屡试屡败屡败试……发现0.2版还算顺利 - -)
接着,到这里下载最新版的codegen配件:https://github.com/rabbitmq/rabbitmq-codegen/downloads ,OR 直接shell:
wget https://github.com/rabbitmq/rabbitmq-codegen/tarball/master
tar zxvf master
mv rabbitmq-* codegen
(上面这步必须要把其解压,并放到rabbitmq-c的目录中的codegen目录中,也就是上面最后那步做的。)
按照手册介绍,先进行:
autoreconf -i
如果你一切顺利,没有报错,那么恭喜了!后面则是常规操作:
./configure && make && make install
如果仍未报错,哇塞,我只能说你NB!可以直接进行扩展编译了。
不过大部分情况下你或许和我一样遇到各种各样报错信息,那么后面我们再说,这里先把编译扩展顺带说完。
直接回到官方下载(我下载的是1.0.0版,新的版本我没事试,应该也可以的) http://pecl.php.net/package/amqp ,并编译成so文件 OR shell:
wget http://pecl.php.net/get/amqp-1.0.0.tgz
tar zxvf amqp-1.0.0.tgz
cd amqp-1.0.0
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-amqp
make && make install
(/usr/local/php/bin/phpize 和 /usr/local/php/bin/php-config 为实际php所在目录,如果不清楚,可以whereis php查看。)
如果之前的步骤顺利,这步应该没什么问题,直接在php.ini中添加生成的amqp.so,重启httpd或php-cgi即可,不再赘述。

好了,如果你和我一样悲催,从autoreconf -i就开始作死地报错,那么我这里提供一些可能有用的处理方法。
autoreconf 时有可能遇到如下报错:
onfigure.ac:60: error: possibly undefined macro: AS_CASE
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:69: error: possibly undefined macro: AS_IF
configure.ac:92: error: possibly undefined macro: AC_PATH_PROGS_FEATURE_CHECK
configure.ac:97: error: possibly undefined macro: AC_MSG_RESULT
configure:2907: error: possibly undefined macro: m4_foreach_w
autoreconf: /usr/bin/autoconf failed with exit status: 1
奇怪的是,当我再次执行却报不同的错。。。
configure.ac: installing `./install-sh'
configure.ac: installing `./missing'
configure.ac:34: installing `./config.guess'
configure.ac:34: installing `./config.sub'
Makefile.am:3: Libtool library used but `LIBTOOL' is undefined
Makefile.am:3:
Makefile.am:3: The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
Makefile.am:3: to `configure.ac' and run `aclocal' and `autoconf' again.
Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac'
Makefile.am: installing `./compile'
Makefile.am: installing `./depcomp'
autoreconf: automake failed with exit status: 1
首先确保一些必要的依赖库是否已安装,如:libtool、autoconf、automake 等
这个大家自行google下载并编译安装,常规操作,没啥说的,这里我直接yum了:
yum install libtool autoconf automake
看下libtoolize在哪:
whereis libtoolize
显示例如:libtoolize: /usr/bin/libtoolize,则可执行一下
/usr/bin/libtoolize
---------------------------------------------------我是分割线----------------------------------------------------
/usr/bin/libtoolize 时可能会报的错:
libtoolize: putting auxiliary files in `.'.
libtoolize: linking file `./ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
报错很明确,按照提示操作即可:
编辑:configure.ac
添加一行:AC_CONFIG_MACRO_DIR([m4])
重新执行:/usr/bin/libtoolize
编辑:Makefile.am
添加一行:ACLOCAL_AMFLAGS=-I m4
---------------------------------------------------我是分割线----------------------------------------------------
./configure 时可能会报的错:
checking location of AMQP codegen directory... configure: error: could not find AMQP spec file at "'/codegen/amqp-0.9.1.json'"
configure文件中目录与实际情况不符,虽然可以通过手动修改解决,但不建议,其实应该是rabbitmq-c和codegen的版本不匹配造成的,更换版本。
checking finding a python with simplejson installed... configure: error: could not find a python that can 'import simplejson'
很明显,该错误是由于python缺少simplejson包造成,可通过easy_install方式安装即可。

还有更多报错情况,没有一一记录,总之解决方法就是:“报错信息”+“google”!
BTW:相信搜一会儿你就会由衷得体会到:F*CK THE GFW!!!
