tar -zxvf libmemcached-1.0.16.tar.gz
cd libmemcached-1.0.16
./configure -prefix=/usr/local/libmemcached -with-memcached
make && make install报错:

tar -zxvf memcached-2.1.0.tgz
cd memcached-2.1.0
/usr/local/php/bin/phpize
./configure -enable-memcached -with-php-config=/usr/local/php/bin/php-config -with-zlib-dir -with-libmemcached-dir=/usr/local/libmemcached -prefix=/usr/local/phpmemcached
make && make install报错:
memcache support requires ZLIB
解决办法yum install zlib-devel
记录下安装成功后的提示,类似于:Installing shared extensions: /usr/lib/php/modules/
7.增加扩展extension配置文件vi /etc/php.d/memcached.ini
增加1行extension=memcached.so
最后验证一下是否安装完成php -m|grep memcached
应该会显示memcached
8.重启nginx/apache,重启php-fpm,使用phpinfo()查看memcached模块是否安装成功。
memcached能启动但无法用php连接的问题(浏览器打开包含memcached的页面,firebug报500错误)
1.SELINUX=enforcing
改为 SELINUX=disabled
2.在终端尝试使用:telnet localhost 11211
或者telnet 127.0.0.1 11211
来连接到memcached的服务器
如果提示bash: telnet: command not found
执行:yum install telnet -y
,再次回到浏览器尝试打开。
