Gearman, Memcached, PHP Gearman PECL
This a short Tutorial on Howto Install Gearman with libdrizzel, libmemcached and the Gearman PHP PECL Extension on Debian. It also works on Ubuntu, you just have to use the sudo wrapper.
I presume you have a complete LAMP Stack, gcc, g++ and make installed.
Installing required libs
apt-get install memcached php5-memcache php5-dev
apt-get install libevent-dev uuid-dev autoconf
Getting the Files you need
wget http://launchpad.net/gearmand/trunk/0.11/+download/gearmand-0.11.tar.gz
wget http://launchpad.net/libdrizzle/trunk/0.7/+download/libdrizzle-0.7.tar.gz
wget http://launchpad.net/libmemcached/1.0/0.38/+download/libmemcached-0.38.tar.gz
Note: I know that there is Gearman 0.12, but this currently doesn’t work with the PHP PECL Client.

Installing libdrizzle
tar -xzvf libdrizzle-0.7.tar.gz
cd libdrizzle-0.7
./configure
make
make install
Installing libmemcached
tar -xzvf libmemcached-0.38.tar.gz
cd libmemcached-0.38
./configure
make
make install
Installing Gearmand
tar -xzvf gearmand-0.11.tar.gz
cd gearmand-0.11
./configure
make
make install
Installing PHP Gearman PECL Extension
pecl install --force gearman
Loading PECL Extension
nano /etc/php5/apache2/php.ini
Look for the Dynamic Extensions Section and add
extension=gearman.so
After that the Webserver must be restarted.
Starting the gearmand Deamon
/usr/local/sbin/gearmand --pid-file=/var/run/gearman.pid --log-file=/var/log/gearman.log --job-retries=3 -d -u root
Starting the gearmand Deamon (with libdrizzle)
/usr/local/sbin/gearmand --pid-file=/var/run/gearman.pid --log-file=/var/log/gearman.log --job-retries=3 -d -u root -q libdrizzle --libdrizzle-host=127.0.0.1 --libdrizzle-user=gearman --libdrizzle-password=mysqlpasswd --libdrizzle-db=gearman --libdrizzle-table=gearman_queue --libdrizzle-mysql
Note: If the MySQL settings are no correct, the Deamon will not start and also not throw an exception. So if you are using libdrizzle and the server does not start, check your mysql settings!
Troubleshooting
gearmand doesn’t start complaining about missing shared objects (.so)
Check your library include path.
nano /etc/ld.so.conf.d/libc.conf
this should look like this:
# libc default configuration
/usr/local/lib
Then try
libconf
fixed it for me :).
