gearman学习笔记

<?php
  搭建描述：
  . 在实际使用时应该是运行gearmand -d 的 server 一台. [要装gearmand,运行gearmand]

  . 处理worker的机器若干[要装gearmand 及php.so但gearmand不需要运行].

  . 下达任务client若干[要装gearmand 及php.so但gearmand不需要运行].

  . worker 与 client 不会直接通信,都是通过gearmand分发处理的.

 上面是一个同步请求的例子,其实gearman可以异步处理,把client端里的代码 do函数 换成 doBackground函数就可以了.

第一步：安装
wget https://launchpad.net/gearmand/1.2/1.1.12/+download/gearmand-1.1.12.tar.gz 

  遇到错误 ： 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..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.  见下文描述的一些有用的变量

        在括号中指定选项的默认值。

        Configuration:
          -h, --help              显示这个帮助并退出
              --help=short        特定于这个包显示选项
              --help=recursive    显示所有包含包的短期帮助
          -V, --version           显示版本信息并退出
          -q, --quiet, --silent   不打印“检查…的消息
              --cache-file=FILE   缓存中测试结果文件(禁用)
          -C, --config-cache      alias for `--cache-file=config.cache'
          -n, --no-create         不创建输出文件
              --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]
          --sbindir=DIR           system admin executables [EPREFIX/sbin]
