memcacheq能不能在window环境下安装使用
刚开始接触memcacheq,有没有前辈帮忙介绍下。这款能不能在window下安装。和介绍下使用的方法咯。小弟感激不尽。

------解决方案--------------------
memcacheQ是一个单纯的分布式消息队列服务。它的安装依赖于BerkeleyDB 和 libevent,所以要先安装这BerkeleyDB和libevent:
  一,BerkeleyDB
  下载软件包,http://download.oracle.com/berkeley-db/db-5.0.21.tar.gz
  解压缩后,cd build_unix
  /dist/configure
  make
  sudo make install
  二,libevent (需要1.4.x 或更高)
  下载软件包:http://monkey.org/~provos/libevent/
  解压缩后configure & make & make install
  三,memcacheQ
  下载软件包:http://code.google.com/p/memcacheq/downloads/list
  解压缩,cd进目录
  ./configure --with-bdb=/usr/local/BerkeleyDB.5.0 --with-libevent=/usr/local/lib --enable-threads
  make
  sudo make install
  将bdb的库添加到共享库路径中
  cd /etc/ld.so.conf.d
  touch bdb.conf
  vim bdb.conf
  增加:
  /usr/local/lib
  /usr/local/BerkeleyDB.5.0/lib
  cd /etc/profile.d
  touch bdb.sh
  vim bdb.sh
  增加
  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/local/BerkeleyDB.5.0/lib
  四,启动memcacheQ
  使用memcacheq -h 的命令来查看命令行选项
  启动memcacheq:memcacheq -d -r -H /data1/memcacheq -N -R -v -L 1024 -B 1024 > /data1/mq_error.log 2>&1
  五,使用
  使用以上命令启动mq后,(注意上面的-B参数表示messag的body长度不能超过1024 bytes),使用mq时只需要用到两个命令:set和get:
  set 0
  
  STOREDget
  VALUE
  
  END可以看到,和memcache协议基本一致,只是把key name换成queue name,而且在set的命令中,忽略了expire_time的参数。毕竟mq的数据存储是存在berkeleyDB中,做了持久化存储,没有内存的过期时间。
  当使用set命令时,就向指定的消息队列中写入了一条新消息,也就是向BerkeleyDB中新insert了一条数据,当使用get命令时,就从 指定队列中取出一条新消息,也就是向BerkeleyDB中delete了一条数据。当使用stats查看一个指定队列时,可以看到这个队列一共接收了多 少消息,其中被取出了多少条。
  示例:
[email protected]:~$ telnet 127.0.0.1 22202
  Trying 127.0.0.1…
  Connected to 127.0.0.1.
  Escape character is ‘^]’。
  set q4 0 0 5
  hello
  STORED
  set q4 0 0 5
  world
  STORED
  stats queue
  STAT q4 2/0
  END
  get q4
  VALUE q4 0 5
  hello
  END
  stats queue
  STAT q4 2/1
  END
  上面执行了两次set的命令,使用stats queue查看时,可以看到q4的队列中共有消息2条,已取出0条;当使用get取出第一条后,再此使用stats queue查看,q4中消息有2条,其中已取出1条。

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
