how to install Separate memcache server on ubuntu and Use from other server ?

Hi!

You are on the correct path. Once you’ve configured memcached to listen on the private IP address, you need to configure PHP to connect to that IP address for memcached.

Open /etc/php5/fpm/php.ini in your favorite text editor and update the following settings:

session.save_handler = memcache
session.save_path = 'tcp://10.1.1.1:11211'

Finally, restart php5-fpm so that the changes take effect:

sudo service php5-fpm restart

If you still get a 500 error after doing that, check nginx’s error logs (which is where php5-fpm’s errors should go) and see if there are any details in there:

sudo tail -20 /var/log/nginx/error.log

hey @kamaln7 thanks for response , yes i have checked the php based web server’s error logs , that says 2016/04/29 05:01:28 [error] 4355#0: *494 FastCGI sent in stderr: "PHP message: PHP Fatal error: Class 'Memcached' not found in /var/www/test.php .

So when i install memcached on web server apt-get install php5-memcached , & added in php.ini extension = memcached.so , than php web server start connected to remotely memcached server , now everything works fine ,

So is this right way to connect other server ? do we have too install memcached in web server ?
