##Using Gearman and other tools

###1. Gearman Server

1. Start the gearmand daemon by running sudo service gearmand start.
2. This will start the daemon on port number 4730 by default
3. You can verify by telnet 127.0.0.1 4730.

###2. Gearman Manager

1. Start the gearman manager daemon by running sudo service gearman-manager start.
2. By default, it will launch 3 workers for each of the functions fetch_url and reverse_string. These workers are located in ${GEARMAN_MANAGER_DOWNLOAD_DIR}/GearmanManager/lib/pecl-workers as specified in GLOBAL
3. The conf file for gearman manager is located in GEARMAN_MANAGER_CONF in GLOBAL
4. You can check if the workers are launched by the following command

telnet 127.0.0.1 4730 Once you are connected run status command. The output should be following:

status
reverse_string	0	0	3
fetch_url	    0	0	3

The same can also be seen through gearmanui

###3. Gearman UI

1. Once, you have followed the post installation steps, check the config file in ${GEARMAN_UI_DIR}/gearmanui/config.yml - refer GLOBAL. By default the UI points to gearman server on localhost.
2. Once you hit the url in the browser, you should be able to see the same thing as the telnet interface.

1. Add init scripts for gearmand and gearman-manager.
2. Replace yum update with only the needed packages.
