php memcache安装与注意事项
装php教程扩展:windows 下的 memcache步骤
1.下载php的扩展dll:http://downloads.php.net/pierre/
2.将.dll放入php的扩展目录下面,一般在php目录中的ext 文件夹中。
3.修改apache目录下bin文件夹中的php.ini,加上extension=php_memcache.dll即可。
4.重启apache服务器,用phpinfo()查看,出现memcache说明配置正确.
值得注意的是:
必须注意php的编译版本,下载memcache的时候注意要使用同样的编译版本;比如php是使用vc6编译的,那么memcache也应该使用vc6编译版本
下面来看一篇在windows下载安装memcache php教程吧
windows下的memcache安装:
1. 下载memcache的windows稳定版,解压放某个盘下面,比如在c:memcached
2. 在终端(也即cmd命令界面)下输入 ‘c:memcachedmemcached.exe -d install’ 安装
3. 再输入: ‘c:memcachedmemcached.exe -d start’ 启动。note: 以后memcached将作为windows的一个服务每次开机时自动启动。这样服务器端已经安装完毕了。
4.下载php_memcache.dll,请自己查找对应的php版本的文件
5. 在c:winntphp.ini 加入一行 ‘extension=php_memcache.dll’
6.重新启动apache,然后查看一下phpinfo,如果有memcache,那么就说明安装成功!
memcached的基本设置:
-p 监听的端口
-l 连接的ip地址, 默认是本机
-d start 启动memcached服务
-d restart 重起memcached服务
-d stop|shutdown 关闭正在运行的memcached服务
-d install 安装memcached服务
-d uninstall 卸载memcached服务
-u 以的身份运行 (仅在以root运行的时候有效)
-m 最大内存使用,单位mb。默认64mb
-m 内存耗尽时返回错误,而不是删除项
-c 最大同时连接数,默认是1024
-f 块大小增长因子,默认是1.25
-n 最小分配空间,key+value+flags默认是48
-h 显示帮助
memcache环境测试:
运行下面的php文件,如果有输出this is a test!,就表示环境搭建成功。开始领略memcache的魅力把!
$mem = new memcache;
$mem->connect(”127.0.0.1′, 11211);
$mem->set(’key’, ‘this is a test!’, 0, 60);
$val = $mem->get(’key’);
echo $val;
?>
