Could not establish Memcached connection

Question

I'm trying to create a connection from my PHP application to Memcache, however I keep getting the error 'Could not establish Memcached connection'.

Here's my package version information

Laravel Version: 5.0.32
PHP Version:5.4.39-0+deb7u2
Database Driver & Version:mysql Ver 14.14 Distrib 5.5.31
Server&Version :Debian:7.1.
-memcached:1.4.13-0.2
-php5-memcached:2.0.1-6

I have ensured that memcached is running, as executing service memcached status yields "memcached is running".

I have two servers where my project is deployed:

• ubuntu, with memcached:2.1.0 installed
• debian, with memcached:2.0.1 installed

Is there a version conflict?

Answer 1

Fixed by myself. My solution as follow: 1.delete memcache file and apc file in config dir 2.restart php5-fpm and memcached service. Although issue is fixed, but I'm still not figure out why it was triggered. This issue only occurs on the server with Debian os installed rather than the other server which with ubuntu os installed. Hope help somebody~

我用sudo apt-get install memcached sudo service memcached status sudo service memcached start解决了这个问题sudo apt-get install memcached sudo service memcached status sudo service memcached start

You need to first install memcached :

sudo apt install memcached

Then you need to start it :

sudo service memcached start

After that it will connect. I resolve it by above step in my case.
