The Memcached set command is used to store values in the specified key.

 

 

If the set key already exists, this command can update the original data corresponding to the key.

Set key flags exptime bytes [noreply]

Value

Parameters are described as follows:

Key: the key in the key-value structure, used to find the cache value.

Flags: it can include an integer parameter of a key-value pair. The client uses it to store additional information about the key-value pair.

Exptime: the length of time for saving the key-value pair in the cache (in seconds, 0 indicates permanent)

Bytes: the number of bytes stored in the cache.

Noreply (optional): This parameter indicates that the server does not need to return data.

Value: the stored value (always in the second row) (which can be directly understood as the value in the key-value structure)

 

Set key1 0 300 3 // set key value: key1, flags: 0, expiration period: 300 seconds, number of bytes: 3 (key value differentiation word)

ABC // set the value corresponding to the key (in the second row). The value is displayed successfully.STORED

 

Get Key1 // Value

The Memcached add command is used to store value (data value) in the specified key.

If the add key already exists, the data will not be updated, the previous values will remain the same, and you will get the response NOT_STORED.

 

The Memcached get command gets the value (data value) stored in the key. If the key does not exist, null is returned.

To configure Tomcat, I use a apache-tomcat-7.0.40-windows-x64 here, unzip to the C: \ Tomcat directory,

 

Configure tomcat environment variables in path

 

 

 

 

Run startup. bat in the bin directory and enable http: // localhost: 8080.

 

 

 

Memadmin is a php file and does not support php by default.

 

 

I need to download the php component.Php-5.6.29-Win32-VC11-x64

 

Create a php folder in the tomcat root directory and decompress it.Php-5.6.29-Win32-VC11-x64To the php Directory,

Copy php. ini-development in the php Directory and name it php. ini. Modify the php. ini content.

 

Modify the context. xml <Context> In the tomcat directory and add the privileged = "true" attribute. <Context privileged ="True">

Modify web. xml under tomcat's webapps \ ROOT \ WEB-INF directory

Add the php path to the <web-app> label. The final result is as follows:

 

<?xml version="1.0" encoding="ISO-8859-1"?><web-app xmlns="http://java.sun.com/xml/ns/javaee"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"  version="3.0"  metadata-complete="true">  <servlet>     <servlet-name>php</servlet-name>     <servlet-class>org.apache.catalina.servlets.CGIServlet</servlet-class>     <init-param>       <param-name>clientInputTimeout</param-name>       <param-value>200</param-value>     </init-param>     <init-param>       <param-name>debug</param-name>       <param-value>0</param-value>     </init-param>     <init-param>       <param-name>executable</param-name>       <param-value>C:\Tomcat\apache-tomcat-7.0.40\php\php-cgi.exe</param-value>     </init-param>     <init-param>         <param-name>passShellEnvironment</param-name>     <param-value>true</param-value>     </init-param>     <init-param>       <param-name>cgiPathPrefix</param-name>       <param-value>WEB-INF/memadmin</param-value>     </init-param>     <load-on-startup>5</load-on-startup>     </servlet>    <servlet-mapping>        <servlet-name>php</servlet-name>        <url-pattern>/memadmin/*</url-pattern>     </servlet-mapping></web-app>

 

 

Download the MemAdmin file http://www.junopen.com/memadmin/, decompress it to the Tomcat web‑root‑web-inf directory, and rename it to memadmin.

 

Open http: // localhost: 8080/memadmin/index. php.

 

 

Php lacks php_memcache.dll,Php_memcache.dllAnd phpTry your bestOtherwise, the above Memcache is not installed.Extension,

Download php_memcache.dll and put it into the php \ ext directory. Modify php \ php. ini and add extension = php_memcache.dll. Then restart tomcat. Then, the system comes in.

Http: /localhost: 8080/memadmin/index. php
