php的memcached扩展

1。安装libmemcached 下载 libmemcached1.0.16： wget https://launchpad.net/libmemcached/1.0/1.0.16/download/libmemcached-1.0.16.tar.gz tar -xzflibmemcached-1.0.16.tar.gz ./configure -prefix=/usr/local/libmemcached -with-memcached=/usr/local/

1。安装libmemcached

下载 libmemcached1.0.16：

wget  https://launchpad.net/libmemcached/1.0/1.0.16/+download/libmemcached-1.0.16.tar.gz

tar -xzf libmemcached-1.0.16.tar.gz

./configure -prefix=/usr/local/libmemcached -with-memcached=/usr/local/memcached/bin/memcached

make

出现如下错误

经查，发现是gcc版本问题

于是先更新gcc版本

yum install gcc44 gcc44-c++ libstdc++44-devel

export CC=/usr/bin/gcc44

export CXX=/usr/bin/g++44

重新执行libmemcached 的 configure：

./configure -prefix=/usr/local/libmemcached -with-memcached=/usr/local/memcached/bin/memcached

make

make install

成功了

2。安装php的memcached扩展

cd memcached-1.4.5;

执行了几次/usr/local/php/bin/phpize，都报如下错误

Cannot find config.m4. 
Make sure that you run '/usr/local/php/bin/phpize' in the top level source directory of the module

后来发现这个不是php的memcached的扩展目录，然后找到memcached的php扩展目录memcached-1.0.2，苍天，我哪儿知道这个是memcached的php扩展目录啊，我还以为是低版本的memcached软件的源代码目录呢。

cd memcached-1.0.2;

执行

/usr/local/php/bin/phpize

世界变得美好了，先把结果拷贝到一个记事本里

然后执行./configure --with-php-config=/usr/local/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached

命运依然多舛，又报错

make: *** [php_memcached.lo] 错误 1

发现是libmemcached版本过高，换低版本

然后继续configure，make ，make install

成功，真不容易

然后在php.ini中增加extension = "memcached.so"

重启php-fpm和webserver（我这边用的是nginx）
