gearman學習筆記

<?php 
  搭建描述：
  1. 在實際使用時應該是運行gearmand -d 的 server 一臺. [要裝gearmand,運行gearmand]
  
  2. 處理worker的機器若干[要裝gearmand 及php.so但gearmand不須要運行].
 
  3. 下達任務client若干[要裝gearmand 及php.so但gearmand不須要運行].
 
  4. worker 與 client 不會直接通訊,都是經過gearmand分發處理的.
 
 上面是一個同步請求的例子,其實gearman能夠異步處理,把client端裏的代碼 do函數 換成 doBackground函數就能夠了.


 
第一步：安裝
wget https://launchpad.net/gearmand/1.2/1.1.12/+download/gearmand-1.1.12.tar.gz 
 
  遇到錯誤 ： gearman configure: error: could not find boost
  yum install -y boost boost-devel  
  yum install -y gperf rperf-devel 
  yum install -y libuuid libuuid-devel
   
 tar -zxvf gearmand-1.1.12.tar.gz  
  ./configure --
  
  `configure' configures gearmand 1.1.12 to adapt to many kinds of systems.

        Usage: ./configure [OPTION]... [VAR=VALUE]...

        To assign environment variables (e.g., CC, CFLAGS...), specify them as
        VAR=VALUE.  見下文描述的一些有用的變量

        在括號中指定選項的默認值。

        Configuration:
          -h, --help              顯示這個幫助並退出
              --help=short        特定於這個包顯示選項
              --help=recursive    顯示全部包含包的短時間幫助
          -V, --version           顯示版本信息並退出
          -q, --quiet, --silent   不打印「檢查…的消息
              --cache-file=FILE   緩存中測試結果文件(禁用)
          -C, --config-cache      alias for `--cache-file=config.cache'
          -n, --no-create         不建立輸出文件
              --srcdir=DIR        find the sources in DIR [configure dir or `..']

        Installation directories:
          --prefix=PREFIX         install architecture-independent files in PREFIX
                                  [/usr/local]
          --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                                  [PREFIX]

        By default, `make install' will install all the files in
        `/usr/local/bin', `/usr/local/lib' etc.  You can specify
        an installation prefix other than `/usr/local' using `--prefix',
        for instance `--prefix=$HOME'.

        For better control, use the options below.

        Fine tuning of the installation directories:
          --bindir=DIR            user executables [EPREFIX/bin]
