PHP連接Memcached
先安裝php的memcache擴展
# wget http://ip/data/attachment/forum/memcache-2.2.3.tgz
# tar zxf memcache-2.2.3.tgz
# cd memcache-2.2.3
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config
# make && make install
安裝完後會有類似這樣的提示：
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
把這個記住，然後修改php.ini，把 extension_dir = "./"
修改為extension_dir = "/usr/local/servers/php5/lib/php/extensions/no-debug-non-zts-20090626/"
並添加一行extension="memcache.so"
PHP連接Memcached 檢驗
/usr/local/php/bin/php -m |grep memcache
下載測試php腳本 curl ip/study_v2/.memcache.txt > 1.php 2>/dev/null /usr/local/php/bin/php 1.php
Memcached 實現session共享
本實例是在lamp/lnmp環境下實現 編輯php.ini添加兩行
session.save_handler = memcache
session.save_path = "tcp://192.168.0.9:11211"
或者httpd.conf中對應的虛擬主機中添加
php_value session.save_handler "memcache"
php_value session.save_path "tcp://192.168.0.9:11211"
或者php-fpm.conf對應的pool中添加 php_value[session.save_handler] = memcache
php_value[session.save_path] = " tcp://192.168.0.9:11211 "

Memcached session測試
wget http://ip/.mem_se.txt mv .mem_se.txt
/usr/local/apache2/htdocs/session.php curl localhost/session.php
