Install Sharedance on CentOS/RHEL
So as to store the information, Sharedance needs an unfilled registry regardless. As a matter of course, it will pick/tmp/sharedance, however you’re unequivocally urged to change this. In case you’re not wanting to store gigantic information and on the off chance that you require great pace, utilize a memory filesystem like tmpfs (Linux/Solaris) or mfs (BSD). As huge amounts of documents can be made in this index, a cutting edge filesystem like ReiserFS or UFS+dirhash is emphatically prescribed.
SERVER IP: 192.168.1.5
SESSION DIRECTORY: /VAR/SHAREDANCE
WEBSERVER #1: 192.168.1.11
WEBSERVER #2: 192.168.1.12
Step 1: We will utilize RPMforge to make our life simpler.
# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt # rpm -Uhv http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
Step 2: Introduce Sharedance utilizing yum.
# yum install sharedance -y
Step 3: I need Sharedance to listen to the primary IP and store close ought to be 6 hours. Open /etc/sysconfig/sharedance bvia text editor and verify you have taking after line.
You can use taking after order to check the complete rundown of alternatives accessible.
# sharedanced --help
Step 4: Verify it is auto begin on boot and begin the Sharedance service.
# chkconfig sharedance on # service sharedance start
Step 5: You can check in the process list this 2 courses of action ought to exist and listening to port 1042.
# ps aux | grep sharedanced
496 2621 0.0 0.0 111520 568 ? Ss 11:44 0:00 sharedanced [SERVER] 496 2622 0.0 0.0 111520 352 ? SN 11:44 0:00 sharedanced [CLEANUP]
# netstat -tulpn | grep sharedanced tcp 0 0 192.168.0.171:1042 0.0.0.0:* LISTEN 2621/sharedanced [SERVER]
To allow firewall rules in iptables for Sharedance port:
# iptables -I INPUT -p tcp --dport 1042 -j ACCEPT
Step 6:We have to duplicate the PHP session handler and sharedance PHP record gave by Sharedance which is situated under/usr/share/doc/sharedance-0.6/php/ direcotry to all web group hubs so they can prepend in the php.ini. I will duplicate them to /ect/php.d registry in all hubs.
# cd /usr/share/doc/sharedance-0.6/php/ # scp session_handler.php sharedance.php 192.168.1.11:/etc/php.d/ # scp session_handler.php sharedance.php 192.168.1.12:/etc/php.d/
Step 1: Change the php.ini value of your server as below:
auto_prepend_file = /etc/php.d/session_handler.php session.save_handler = user
Step 2: Alter /etc/php.d/ session_handler.php utilizing content manager and verify the first line contain the IP location of Sharedance server.
Step 3: Restart Apache web server to apply the changes:
# service httpd restart
I download this document: http://blog.secaserver.com/documents/session.tar.gz and execute it from the web server to get taking after result.
We should see the same session ID exist in Sharedance session directory at /var/lib/sharedance:
# ls -al | grep tqsncjk23k78cqwerm747n4b1eq5l4 -rw------- 1 sharedance sharedance 24 Aug 1 12:17 tqsncjk23k78cqwerm747n4b1eq5l4
