    @b247_eu @rmdes I have pushed changes to the memcached branch. It removed redis addon and adds memcached instead. https://git.cloudron.io/cloudron/php7.3-postgres-app/-/commit/12c40aba6a3f05ad245290882fef9743bafed7c5

    One you install the app, memcached is running on port 11211 on localhost. You can test this with:

    root@a95330af-2470-45e7-a7cb-fe170bd184ed:/app/data# echo "stats settings" | nc localhost 11211
    STAT maxbytes 67108864
    STAT maxconns 1024
    STAT tcpport 11211
    STAT udpport 0
    STAT inter 127.0.0.1
    STAT verbosity 0
    STAT oldest 0
    STAT evictions on
    STAT domain_socket NULL
    STAT umask 700
    STAT growth_factor 1.25

        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.

              @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).

                            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 !
