Centos给php安装cassandra扩展
一、准备
当前php版本PHP Version 5.5.10，首先去http://pecl.php.net/package/cassandra，找到对应的php版本
二、下载安装
# wget http://101.110.118.47/pecl.php.net/get/cassandra-1.2.1.tgz
# tar -zxvf cassandra-1.2.1.tgz
# cd cassandra-1.2.1
# /usr/local/php/bin/phpize
# ./configure
遇到的一系列报错
报错①：checking for supported DataStax C/C++ driver version... gawk: cmd. line:1: fatal: cannot open file `/include/cassandra.h' for reading (No such file or directory)
checking for supported DataStax C/C++ driver version... gawk: cmd. line:1: fatal: cannot open file `/include/cassandra.h' for reading (No such file or directory)
解决：需要安装cpp的drive
当前所在目录/usr/local/src下执行以下命令
# git clone https://github.com/datastax/cpp-driver.git
# mkdir cpp-driver/build
# cd cpp-driver/build
# cmake ..
# make
报错②：configure: error: Unable to load libuv
configure: error: Unable to load libuv
解决：
# wget https://github.com/libuv/libuv/archive/ v1.4.2.tar.gz
# tar -zxvf v1.4.2.tar.gz
# cd /usr/local/src/libuv-1.4.2
# sh autogen.sh
# ./configure
# make
# make install
报错③：/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h:No such file or directory
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h:No such file or directory
解决：
# yum -y install glibc-devel.i686
报错④： WARNING: You will need re2c 0.13.4 or later if you want to regenerate PHP parsers.

报错⑤：/usr/local/src/cpp-driver/src/event_loop.cpp:63: error: ‘uv_print_all_handles’ was not declared in this scope
/usr/local/src/cpp-driver/src/event_loop.cpp:63: error: ‘uv_print_all_handles’ was not declared in this scope
解决：百度、360、必应、谷歌都走了，出现类似错误的很多（was not declared in this scope），但是没有一个完全对应的解决方案，反正意思就是函数不存在。
简单粗暴，编辑/usr/local/src/cpp-driver/src/event_loop.cpp:63文件
# vim /usr/local/src/cpp-driver/src/event_loop.cpp
//然后找到63行，把整行删掉 // uv_print_all_handles(loop(), stderr);
把一系列问题解决之后，在当前目录下/usr/local/src/cassandra-1.2.2
# make
# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/ //ok，然后在php.ini里开启cassandra扩展就可以了
编辑php.ini文件
#vim /usr/local/php/etc/php.ini
//增加
extension=cassandra.so
然后重启php服务
意外！！！！意外！！！！TMD~~~
报错⑥：
NOTICE: PHP message: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/cassandra.so' - libcassandra.so.2: cannot open shared object file: No such file or directory in Unknown on line 0

TMD明明目录下有cassandra.so文件，可TMD说没有。。。
解决：
百度到一个帖子说：这个问题是缺少/usr/local/lib64/libcassandra.so.2文件，经查找发现/usr/lib64/libcassandra.so.2存在，创建软件接至lib64中
ln -s /usr/local/lib64/libcassandra.so.2 /usr/lib64/libcassandra.so.2
提示⑦：
在make install的时候还报过这玩意儿？？？？？

在SF看到的答案：
这是告诉你接下来要怎么用。简单的办法是在 /etc/ld.so.conf.d 下新建一个文件 local.conf，里边写上 /usr/local/lib。然后以 root 权限执行 ldconfig。这样你的系统才会找得到安装到 /usr/local/lib 下的库文件
# echo "/usr/local/lib" >> /etc/ld.so.conf
# /usr/local/lib/ldconfig
