Conexion fallida usando LSMCD con Apache

    Hi guys,
    I am configuring the W3 Total Cache plugin on my hosting which has the following features:

    – Web server: Apache
    – LSMCD (MemcacheD from LiteSpeed)

    I’m having trouble authenticating (SASL enabled). I have entered the data requested (Object cache configuration > advanced configuration):

    • Memcached hostname:port / IP:port
    • I activate the checkbox: “Persistent connection”
    • Memcached username: Here I enter my username (SASL)
    • Memcached password: Here I enter my password (SASL)

    When I press the “test” button, the connection failed message appears. And I get the following message:

    “The following memcached servers are not responding or not running:

    • Database Cache: 127.0.0.1:11211.
    • Object Cache: 127.0.0.1:11211.
    • Page Cache: 127.0.0.1:11211.

    This message will automatically disappear once the issue is resolved.”

    I have checked with my hosting service to see if they are blocking connections and they responded that they did not apply any type of blocking.

    What could be happening?

    Hello @alexnoxx

    Thank you for reaching out and I am happy to help!

    Check the service at the CLI/SSH: memcached-tool 127.0.0.1:11211 display and memcached-tool 127.0.0.1:11211 stats.

    telnet 127.0.0.1 11211

    should communicate with memcache and respond to status commands etc

    Look if the service is running: ps afux | grep memc

    restart the service if needed (as root/sudo): service memcached restart.

    Please also restart your server if needed.

    Thanks!

    Dear,
    I have proceeded to carry out the requested tests. I have created the following code to demonstrate that the authentication is successful:

    file t.php:
    https://www.interplastsa.com.ar/t.php

    <?php
$mem_var = new Memcached();
$mem_var->setOption(Memcached::OPT_BINARY_PROTOCOL, true);
$mem_var->setOption(Memcached::OPT_COMPRESSION, false);
$mem_var->setSaslAuthData('interplast01', 'xxx');
$mem_var->addServer("127.0.0.1", 11211);
$response = $mem_var->get("SampleKey");
if ($response) {
 echo "get(SampleKey) => " . $response;
} else if ($mem_var->getResultCode() == Memcached::RES_NOTFOUND) {
 echo "Adding a key/value: SampleKey/SampleValue";
 $mem_var->set("SampleKey", "SampleValue") or 
 die("SampleKey Couldn't be Created: '( " . $mem_var->getResultMessage() . 
   " )' ");
} else die ("Error in get: " . $mem_var->getResultCode() . ": " . 
      $mem_var->getResultMessage());
?>

    The answer obtained is:

    get(SampleKey) => SampleValue

    With this test we demonstrate that the authentication is carried out successfully. But it still doesn’t connect memcached:

    Hello @alexnoxx

    Thank you for your feedback.
    Can you please check if the memcached php extension is installed?

    Thanks!

    Dear,
    If the memcached php extension was not installed, the test code presented above would not work (t.php):
    https://www.interplastsa.com.ar/t.php

    In the code cited above it is observed:

    $mem_var = new Memcached();
    The extension is installed and my hosting provider is not applying any blocking.

    Diego
