先介绍安装 Gearman。
1.先安装依赖库
# yum install -y boost-devel gperf libevent-devel libuuid-devel
2.下载 Gearman
下载：
# wget https://launchpad.net/gearmand/1.2/1.1.12/+download/gearmand-1.1.12.tar.gz
解压：
# tar -xzvf gearmand-1.1.12.tar.gz
3.配置 Gearman
# cd gearmand-1.1.12
# pwd
/data/gearmand-1.1.12
# ./configure
...
checking for boostlib >= 1.39... configure: We could not detect the boost libraries (version 1.39 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option. If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.
configure: error: could not find boost
如果出现上面错误，先检查当前安装的Boost版本是否 >= 1.39，如果版本低，就需要安装高版本的Boost。
如果已经安装了Boost，就先卸载再安装；如果版本 >= 1.39，也出现上面错误，也卸载再安装。
安装Boost：
# yum install boost
# yum install boost-devel
# yum install boost-doc
再执行配置：
# ./configure
4.编译 Gearman
# pwd
/data/gearmand-1.1.12
# make
...
CXX util/gearmand_hostile_gearmand-daemon.o
CXX util/gearmand_hostile_gearmand-pidfile.o
CXX libtest/gearmand_hostile_gearmand-cpu.o
CXXLD gearmand/hostile_gearmand
/usr/bin/ld: cannot find -lmysqlclient
collect2: ld returned 1 exit status
make[1]: *** [gearmand/hostile_gearmand] Error 1
make[1]: Leaving directory `/data/backup/gearmand-1.1.12'
make: *** [all] Error 2
如果出现上面错误，就先查找 mysqlclient 库文件所在目录：
# find / -name *mysqlclient*
/usr/lib64/mysql/libmysqlclient.a
/usr/lib64/mysql/libmysqlclient_r.a
如上找到mysqlclient 库文件，就在/usr/lib/目录下建两个软链接：
# ln -s /usr/lib64/mysql/libmysqlclient.a /usr/lib/libmysqlclient.a
# ln -s /usr/lib64/mysql/libmysqlclient_r.a /usr/lib/libmysqlclient_r.a
如果没找到 mysqlclient 库文件，就需要安装 MySQL Client 了。
再执行编译：
# make
5.安装 Gearman
# pwd
/data/gearmand-1.1.12
# make install
随意进入其他目录执行 gearman，检查安装是否成功：
# gearman
gearman Error in usage(No Functions were provided).
Client mode: gearman [options] [<data>]
Worker mode: gearman -w [options] [<command> [<args> ...]]
Common options to both client and worker modes.
-f <function> - Function name to use for jobs (can give many)
-h <host> - Job server host
-H - Print this help menu
-v - Print diagnostic information to stdout(false)
-p <port> - Job server port
-t <timeout> - Timeout in milliseconds
-i <pidfile> - Create a pidfile for the process
-S - Enable SSL connections
Client options:
-b - Run jobs in the background(false)
-I - Run jobs as high priority
-L - Run jobs as low priority
-n - Run one job per line(false)
-N - Same as -n, but strip off the newline(false)
-P - Prefix all output lines with functions names
-s - Send job without reading from standard input
-u <unique> - Unique key to use for job
Worker options:
-c <count> - Number of jobs for worker to run before exiting
-n - Send data packet for each line(false)
-N - Same as -n, but strip off the newline(false)
-w - Run in worker mode(false)
#
出现上面显示，说明安装 Gearman 成功了。
启动与停止 Gearman 服务：
1.启动 Gearman
# gearmand -d --log-file=/data/gearman/logs/gearmand.log
log-file 参数指定日志文件。
2.停止 Gearman
# gearadmin --shutdown
下面讲配置使用 Gearman 的 PHP 扩展环境。
1.先安装PHP拓展环境
下载 gearman-1.1.2.tgz（注意，这个 gearman-1.1.2.tgz 与前面的 gearmand-1.1.12.tar.gz 不同）：
# wget http://pecl.php.net/get/gearman-1.1.2.tgz
（下载列表地址：http://pecl.php.net/package/gearman）
# tar -zxvf gearman-1.1.2.tgz
配置：
# cd gearman-1.1.2
# phpize
如果出现“phpize: command not found”，就安装PHP ：
# yum install php php-devel
然后再执行：
# phpize
Configuring for:
PHP Api Version: 20090626
Zend Module Api No: 20090626
Zend Extension Api No: 220090626
# ./configure
编译安装：
# make
# make install
Installing shared extensions: /usr/lib64/php/modules/
出现如上提示，说明安装成功， 在 /usr/lib64/php/modules/ 目录下有 gearman.so 文件。
2.在php.ini文件中加入Gearman配置
在配置前，先编写个php程序测试下，程序很简单，就是打印 Gearman 版本。
# cd /data/test
# vi test.php
<?php
print gearman_version() . "\n";
?>
然后执行程序看什么结果：
# php test.php
PHP Fatal error: Call to undefined function gearman_version() in /data/test/test.php on line 2
调用了未定义的 gearman_version 函数。
下面加上配置后再运行程序看看。
先找到php.ini文件：
# find / -name php.ini
/etc/php.ini
# cd /etc
为把配置加入适当的位置，先查找文件中 extension 单词出现的位置：
# more php.ini | grep extension
; Directives are variables used to configure PHP or PHP extensions.
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.
; leading '/'. You must also specify the file extension being used including
; Directory in which the loadable extensions (modules) reside.
; http://www.php.net/manual/en/ini.core.php#ini.extension-dir
; extension_dir = "./"
; If you wish to have an extension loaded automatically, use the following
; extension=modulename.extension
; extension=msql.so
; extension=/path/to/extension/msql.so
; If you only provide the name of the extension, PHP will look for it in its
; default extension directory.
; Note: packaged extension modules are now loaded via the .ini files
;sqlite3.extension_dir =
; Sets the directory name where SOAP extension will put cache files.
#
加入配置：
# vi php.ini
extension=gearman.so
位置：
再执行程序：
# php test.php
1.1.12
到此，使用 Gearman 的 PHP 扩展环境配置完成。
