memcached server and php-memcached

[rmdes]

Alright install ran smoothly, now just waiting for feedback from the devs.

[rmdes]

When I test echo "stats settings" | nc localhost 11211 on the web terminal I get :
localhost [127.0.0.1] 11211 (?) : Connection refused

Do I need to make this test under a specific user perhaps ?

@rmdes Can you check if memcached is running at all (just to make sure you selected the correct branch when building). You can do this with supervisorctl status.

root@dfa78176-bd47-44ed-9d07-3e66265886b7:/app/data# supervisorctl status
apache2                          RUNNING   pid 22, uptime 0:00:15
cron                             RUNNING   pid 21, uptime 0:00:15
memcached                        RUNNING   pid 20, uptime 0:00:15
root@dfa78176-bd47-44ed-9d07-3e66265886b7:/app/data# echo "stats settings" | nc localhost 11211

@girish I have

root@659d2867-1273-4c51-b7e7-765edf705c2d:/app/data# supervisorctl status
apache2                          RUNNING   pid 19, uptime 1 day, 22:13:15
cron                             RUNNING   pid 18, uptime 1 day, 22:13:15

@girish I think I did selected the correct branch, because when I do git branch I have this

And I did the build and the install from this branch.

I probably did something wrong tho since memcached is not even running and the test put in place by the devs goes like this :
Fatal error: Uncaught Error: Class 'Memcached' not found in /app/data/public/index.php:24 Stack trace: #0 {main} thrown in /app/data/public/index.php on line 24

if (!$connection = pg_connect ("host=".getenv("CLOUDRON_POSTGRESQL_HOST")." dbname=". getenv("CLOUDRON_POSTGRESQL_DATABASE") ." user=" . getenv("CLOUDRON_POSTGRESQL_USERNAME")." password=" .getenv("CLOUDRON_POSTGRESQL_PASSWORD") ."")) {
    $error = error_get_last();
    echo "Connection to the PostgreSQL database failed. Error was: ". $error['message']. "\n";
} else {
    echo "Connected to the PostgreSQL database.\n";
}

print_r(get_loaded_extensions());

$memcached = new Memcached();
$memcached->addServer('172.18.0.158', 11211);

phpinfo();
exit;

?>

[rmdes]

I got this from the devs of the custom web app :

So far: postgresql and memcached servers available - OK;
Missing: php-memcached extension (so I can't make use of the memcached server capabilities within a php script) - not OK

Please also don't forget about nginx x-accel, can you add an entry to the nginx conf file for that?

---

Not sure how to proceed

[rmdes]

by inspecting php.ini in the container, I went to the extension section and added
extension=memcache

Aug 31 14:29:58 PHP Warning: PHP Startup: Unable to load dynamic library 'memcache' (tried: /usr/lib/php/20180731/memcache (/usr/lib/php/20180731/memcache: cannot open shared object file: No such file or directory), /usr/lib/php/20180731/memcache.so (/usr/lib/php/20180731/memcache.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

So does this mean the memcache server is not properly installed ?

[girish]

I think the image you are using is wrong. php-memcached is also installed in the same patch as memcached itself - https://git.cloudron.io/cloudron/php7.3-postgres-app/-/commit/12c40aba6a3f05ad245290882fef9743bafed7c5#6651ddff6eb82c840ced7c1dddee15c6e1913dd4_8_7

Can you tell me the command you used to build and update the image? Also, what is the CLI version ? It should be 4.5.2.

$ cloudron --version
4.5.2

[rmdes]

@girish I'm on 4.5.2
the command I used after git clone
was cloudron build --local
then cloudron install
and that's it..

[girish]

@rmdes Can you try cloudron exec and then check if /etc/supervisor/conf.d/memcache.conf exists? Otherwise, you are not using the correct build (not sure where the problem could be though).

[rmdes]

@rmdes said in memcached server and php-memcached:

supervisorctl status

Yay!!!!

[rmdes]

Not sure what happened to my original git clone folder but by downloading the zip file from the memcache branch and then doing cloudron build --local & cloudron install I got it working !

[rmdes]

@girish said in memcached server and php-memcached:

/etc/supervisor/conf.d/memcache.conf

Confirm this exists now
