安装php7的memcached扩展

.编译安装libmemcached-1.0.

wget https://launchpadlibrarian.net/165454254/libmemcached-1.0.18.tar.gz

tar -zxvf libmemcached-1.0..tar.gz

cd libmemcached-1.0.

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

make && make install

. 安装php-memcached扩展

php使用memcache的扩展有两个，一个memcache，一个memcached，前者比较老，推荐使用第二个，我们这里以第二个为例：

在github上找到适用于php7的分支（https://github.com/php-memcached-dev/php-memcached/tree/php7），同样使用wget下载zip压缩包，解压缩，进入目录，依次执行下列命令（其中php-config和libmemcached目录根据具体情况设定，可以使用whereis或者find来查找

# 解压

cd php-memcached-php7

# 执行phpize会生成configure文件

/usr/local/php/bin/phpize

# 执行预编译

./configure --enable-memcached --with-php-config=/usr/local/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-sasl

make

make install

[root@szxxlfhtest02t:/usr/local/src/php-memcached-php7]# /usr/local/php/bin/phpize

[root@szxxlfhtest02t:/usr/local/src/php-memcached-php7]# make install

Libraries have been installed in:

   /usr/local/src/php-memcached-php7/modules

If you ever happen to want to link against installed libraries

in a given directory, LIBDIR, you must either use libtool, and

specify the full pathname of the library, or use the `-LLIBDIR'

flag during linking and do at least one of the following:

   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable

     during execution

   - add LIBDIR to the `LD_RUN_PATH' environment variable

     during linking

   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag

   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for

more information, such as the ld() and ld.so() manual pages.

----------------------------------------------------------------------

Build complete.

Don't forget to run 'make test'.

Installing shared extensions:     /usr/local/php-7.0.12_fpm/lib/php/extensions/no-debug-non-zts-/

修改php.ini的配置

加上：extension_dir="/usr/local/php7.1/lib/php/extensions/no-debug-non-zts-20160303/"(每个人的路径可能不一样)

        extension = "memcached.so

重启php-fpm

. 修改php.ini文件

（php.ini文件具体位置可以通过phpinfo()函数来查看到），在php.ini文件之中加入下面这句：

# vim /usr/local/php-7.0.12_fpm/lib/php.ini

extension_dir="/usr/local/php-7.0.12_fpm/lib/php/extensions/no-debug-non-zts-20151012/"

extension=memcached.so

.测试是否安装成功

[root@szxxlfhtest02t:/data/www/vhosts/cmstest.chinasoft.com/httpdocs]# cat mem.php

<?php

$mem  = new Memcached(); //创建一个memcached对象

$mem->addServer('127.0.0.1',);    //连接memcached

$mem->set("key","test");//设置一个变量到内存中，名称是key 值是test

$get_value = $mem->get('key'); //从内存中取出key的值

if($mem->getResultCode() == Memcached::RES_NOTFOUND)    //如果该名称的变量没有设置

{

    echo 'not set!';

}

else

{

    echo $get_value;

}
