Hi,
are you using memcached unix socket ?
make sure your PHP user has permission to read/write to that socket file
Best regards,
Hi @xorred ,
May I know if this is a cloud image launched from marketplace?
If so, the default object cache has set to use unix socket, so check the port command may not help. Please consider to Method Redis, Host set to /var/run/redis/redis-server.sock and Port set to 0.
Best,
Eric

@qtwrk – can you please clarify how I could make sure of that besides the ls -lah, showing the right permissions, same as the webserver and Memcached ‘-u’ user switch? Is there a test I could run?
@eric780217 thanks, Redis works, but I would really like to use Memcached.

Hi,
please create a php file with code
<?php
$mem = new Memcached();
#$mem->addServer("127.0.0.1", 11211);
$mem->addServer('/var/www/memcached.sock',0);
//$mem->connect("127.0.0.1", 11211);
$mem->set('key1', 'This is first value', 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val ."<br />";
$mem->replace('key1', 'This is replace value', 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "<br />";
$arr = array('aaa', 'bbb', 'ccc', 'ddd');
$mem->set('key2', $arr, 60);
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "<br />";
$mem->delete('key1');
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "<br />";
$mem->flush();
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "<br />";
$mem->close();
replace /var/www/memcached.sock to your actual path if it’s different , then access this file via browser, and post what it outputs.

Get key1 value:
Get key1 value:
Get key2 value: Array ( [0] => aaa [1] => bbb [2] => ccc [3] => ddd )
Get key1 value:
Get key2 value:
This is the file’s output.

Hi,
it should output like this
Get key1 value: This is first value
Get key1 value: This is replace value
Get key2 value: Array ( [0] => aaa [1] => bbb [2] => ccc [3] => ddd )
Get key1 value:
Get key2 value:
what’s permission on that memcached.sock file ? and PHP user ?

php user is www-data
permissions on the sock file:
srwxrwx— 1 www-data www-data 0 Aug 18 16:27 memcached.sock

Thought to share the memcached conf here: (ps. I *JUST* changed the port to 0, figured out 11211 was wrong. Output of the test file is still the same…
# memcached default config file
# 2003 - Jay Bonci <[email protected]>
# This configuration file is read by the start-memcached script provided as
# part of the Debian GNU/Linux distribution.
# Run memcached as a daemon. This command is implied, and is not needed for the
# daemon to run. See the README.Debian that comes with this package for more
# information.

# Be verbose
-v
# Be even more verbose (print client commands as well)

# Start with a cap of 64 megs of memory. It's reasonable, and the daemon default
# Note that the daemon will grow to this size, but does not start out holding this much
# memory
-m 128
# Default connection port is 11211
-p 0
# Run the daemon as root. The start-memcached will default to running as root if no
# -u command is present in this config file
-u www-data
# Specify which IP address to listen on. The default is to listen on all IP addresses
# This parameter is one of the only security measures that memcached has, so make sure
# it's listening on a firewalled interface.

Also, changed your code to reflect a socket connection and now it works (seems to)
$mem = new Memcached();
#$mem->addServer("127.0.0.1", 0);
$mem->addServer('/var/www/memcached.sock',0);
//$mem->connect("/var/www/memcached.sock", 0);
$mem->set('key1', 'This is first value', 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val ."<br />";
$mem->replace('key1', 'This is replace value', 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "<br />";
$arr = array('aaa', 'bbb', 'ccc', 'ddd');
$mem->set('key2', $arr, 60);
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "<br />";
$mem->delete('key1');
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "<br />";
$mem->flush();
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);

So you got the test script working with memcached socket now ?

yep. Overall I think this thread can be closed. Thanks a LOT for your help so far!
