          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
            STAT maxbytes 67108864

                @girish I think I did selected the correct branch, because when I do git branch I have this
                10a6b05b-62a2-454e-b2f7-d4d25f997c9b-image.png

                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;
                
                ?>

                  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

                    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 ?

                      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

                        @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..

                          @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 said in memcached server and php-memcached:

                            supervisorctl status

                            Yay!!!!

                              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 !

                                Confirm this exists now 🙂
