nginx+php+memcache Fatal error: Class 'Memcache' not found

安裝過程：

（nginx+php已經安裝完成，僅寫與memcache相關步驟）

[root@zz src]# yum install libevent libevent-devel

[root@zz src]# wget http://pecl.php.net/get/memcache-2.2.5.tgz

[root@zz src]# tar zxvf memcache-2.2.5.tgz

[root@zz src]# cd memcache-2.2.5

[root@zz src]# ./configure --enable-memcache --with-php-config=/opt/php/bin/php-config

[root@zz src]# make && make install

完成後會有“Installing shared extensions: /opt/php/lib/php/extensions/no-debug-non-zts-20090626”提示，最後這個值會不一樣

[root@zz src]# cd /opt/php/etc

[root@zz src]# vi php.ini

 819行： extension_dir = "/opt/php/lib/php/extensions/no-debug-non-zts-20090626"#（貌似是）

添加：extension=memche.so

[root@zz src]# vi /var/www/html/test.php

<?php
$mem = new memcache;
$mem->connect ('127.0.0.1', 11211);
$mem->set('test','hello world!', 0, 12);
$val = $mem->get('test');
echo $val;
?>

在瀏覽器中輸入:localhost:8080，

so，問題來了，無法訪問，查看nginx日誌：

2013/07/09 18:18:13 [error] 3855#0: *84498 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Class 'memcache' not found in /var/www/tjtct/test.php on line 2" while reading response header from upstream, client: 192.168.1.193, server: 192.168.1.242, request: "GET /test.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "192.168.1.242"

解決辦法：

重啟php-fpm

/etc/ini.d/php-fpm restart

重新瀏覽，OK，hello world。 出來了

搞定，結束
