Installing Gearman on OSX Yosemite (usually)

1 Comment

logo

Another round of Gearman installs, following the update to OSX Yosemite. (Updated 12-AUG-2015)

Here is your guide to getting it done!

Make sure you have XCode developer tools

First step is to make sure you have the Command Line developer tools installed. To do this, or verify that it’s already done, while logged in as a non-root user, type:

xcode-select –install

A system dialog box should open up and request that you grant it permission to perform the command line install. Follow the steps and instructions in the dialogs to complete this step.

Collected the Packages

You will need the following packages

  • libevent
  • boost
  • gearmand

libevent

The latest version can be acquired here: http://libevent.org/

Unpack and compile

gunzip libevent-2.0.22-stable.tar.gz

tar xvf libevent-2.0.22-stable.tar

./configure

make install

boost

The latest version can be acquired here:
http://www.boost.org/users/download/

Unpack and compile

gunzip boost_1_58_0.tar.gz

tar xvf boost_1_58_0.tar

./bootstrap.sh

./b2 –a –build-type=complete –layout=versioned

Note: these paths reported by b2 during build are important to save:

The Boost C++ Libraries were successfully built!

The following directory should be added to compiler include paths:

/opt/boost_1_58_0

The following directory should be added to linker library paths:

/opt/boost_1_58_0/stage/lib

Gearman

The latest code can be acquired here: https://launchpad.net/gearmand

It is possible that the compiler won’t find libevent so the following environment variables may need to be set:

export CPPFLAGS=’-I/opt/boost_1_58_0′
export LDFLAGS=’-L/opt/boost_1_58_0/stage/lib’

Unpack and compile

gunzip gearmand-1.1.12.tar.tgz

tar xvf gearmand-1.1.12.tar

./configure –with-boost –with-boost-libdir=/opt/boost_1_58_0/stage/lib –prefix=/opt –with-sanitize –enable-fast-install –with-gnu-ld –enable-ssl

make && make install

At this point, you should be up and running!

Installing Gearman PHP components for OSX

1 Comment

Locating the latest PHP Components

The Gearman.org page has links to the PHP code on the Downloads page, however the link is very old. The latest code is located at: http://pecl.php.net/package/gearman.

As of 23-OCT-2014, the current stable version is gearman-1.1.2.

I like to drop these files in my /opt directory, and work on them there and unball the package.

mv ~/Downloads/gearman-1.1.2.tgz /opt/.
tar xvzf gearman-1.0.2.tgz
cd gearman-1.0.2

Configuring for Build

The following commands prepared the PHP package to build on OSX Yosemite (10.10).

phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212

./configure
checking for grep that handles long lines and -e… /usr/bin/grep
checking for egrep… /usr/bin/grep -E
checking for a sed that does not truncate output… /usr/bin/sed
[…]
appending configuration tag “CXX” to libtool
configure: creating ./config.status
config.status: creating config.h

Building the Library

Next step is to run the compile and install the built objects:

make
/bin/sh /opt/gearman-1.1.2/libtool –mode=compile cc -I. -I/opt/gearman-1.1.2 -DPHP_ATOM_INC -I/opt/gearman-1.1.2/include -I/opt/gearman-1.1.2/main -I/opt/gearman-1.1.2 -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM -I/usr/include/php/Zend -I/usr/include/php/ext -I/usr/include/php/ext/date/lib -I/usr/local/include -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -Wall -c /opt/gearman-1.1.2/php_gearman.c -o php_gearman.lo
mkdir .libs
[…]
Build complete.
Don’t forget to run ‘make test’.

make install
Installing shared extensions: /usr/lib/php/extensions/no-debug-non-zts-20121212/

Telling PHP about gearman

You will need to identify your relevant php.ini file, and edit it, letting PHP know where the library file are located.

Typically under OSX, this file does not exist, and it must be created.

Edit the file:

vi /etc/php.ini

Either way, make sure these two lines are in the file:

Add these lines:

include_path=.:/mnt/crawler
extension=gearman.so

DONE

At this point you should be able to reference Gearman library in your PHP code.

These lines of code, should not throw an error:

$client = new GearmanClient(); // instance
$worker = new GearmanWorker(); // instance

Install Gearman + Gearman-PHP on AWS ec2

1 Comment

The fun and games continue!! As with every Gearman implementation I’ve done, there are trick for each environment. Here are the Cliff Notes (originally sourced from [Planet MySQL page] with my own twist) for getting Gearman setup on an Amazon Web Services (AWS) EC2 (Elastic Computing 2) node running the default AWS distribution. As always, your experience may vary.

Install required libraries

First, get all the required libraries installed using yum:

[ec2-user@]$ sudo yum install -y gcc
[ec2-user@]$ sudo yum install -y gcc-c++
[ec2-user@]$ sudo yum install -y gperf
[ec2-user@]$ sudo yum install -y boost
[ec2-user@]$ sudo yum install -y boost-devel
[ec2-user@]$ sudo yum install -y memcached
[ec2-user@]$ sudo yum install -y libuuid
[ec2-user@]$ sudo yum install -y libuuid-devel
[ec2-user@]$ sudo yum install -y libevent-devel
[ec2-user@]$ sudo yum install -y php-devel
[ec2-user@]$ sudo yum install -y php-xml

Compile Gearmand from Source

Very straight forward config and build.

[ec2-user@]$ cd gearmand-1.1.9
[ec2-user@]$ sudo ./configure --with-boost=/usr/include --prefix=/usr
[ec2-user@]$ sudo make
[ec2-user@]$ sudo make install

Compile Gearman PHP Library from Source

Fairly simple build, but you must first phpize.

[ec2-user@]$ cd gearman-1.1.1
[ec2-user@]$ sudo phpize
[ec2-user@]$ sudo ./configure --prefix=/usr
[ec2-user@]$ sudo make
[ec2-user@]$ sudo make install

Run ldconfig to Reload Dynmaic Library Cache

If you don’t run ldconfig, you’re going to get errors when you edit the php.ini file (last step).


bad:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gearman.so' - libgearman.so.8: cannot open shared object file: No such file or directory in Unknown on line 0
[ec2-user@]$ sudo ldconfig

Edit the PHP ini file

This is the last step.

finding location of your php.ini file
[ec2-user@]$ php -i | grep php.ini
Configuration File (php.ini) Path => /etc
Loaded Configuration File => /etc/php.ini

Edit your config file, adding these lines:

[ec2-user@]$ sudo vi /etc/php.ini
[Gearman]
; Add Gearman shared object to config
extension="gearman.so"

Now your install is complete!!
