这篇文章主要介绍了腾讯CMEM的PHP扩展编译安装方法,较为详细的分析了CMEM的功能、作用及安装使用技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了腾讯CMEM的PHP扩展编译安装方法。分享给大家供大家参考。具体如下:

CMEM是什么?

CMEM全称为Cloud Memory,是腾讯提供的高性能内存级持久化存储服务,适用于数据量小、访问量高、key-value存储的场景。

CMEM基于一个存储键/值对的hashmap,数据使用内存存储,并保证数据的持久性。

CMEM PHP Extension是什么?

CMEM基于标准的Memcached协议以及接口,,只是将数据获取接口增加返回值设定。
Memcached的Get协议没有设计返回码,所以Memcached API返回NO_DATA时,有可能是网络原因造成的,不能完全信任。 使用如下流程将是非常危险的,将造成用户数据初始化:

if(NO_DATA) { InitData(); }

为解决上述问题,CMEM提供了Memcahced文本扩展协议,增加两个扩展的命令get_ext, gets_ext,使客户端可以根据返回码判断数据是否存在。 这样可以避免网络和设备故障时get不到数据而导致用户数据被误初始化。

CMEM编译与安装

# 下载CMEM cd /home/src wget # 解压 tar zxvf cmem-2.2.6.tar.gz cd cmem-2.2.6 # 编译 /usr/local/webserver/php/bin/phpize ./configure --with-php-config=/usr/local/webserver/php/bin/php-config make # 安装PHP扩展 cp modules/cmem.so /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20090626/ # 配置php.ini # 加入以下内容 # -------------------------------------------------- extension = "cmem.so" # -------------------------------------------------- # 测试 # 新建cmemtest.php cat > /tmp/cmemtest.php # 代码为 # -------------------------------------------------- # -------------------------------------------------- # 执行测试文件 /usr/local/webserver/php/bin/php -f /tmp/cmemtest.php
