https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=22217 Bug ID: 22217 Summary: error "Connection to the memcached servers '__MEMCACHED_SERVERS__' failed" during install Change sponsored?: --- Product: Koha Version: 18.11 Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P5 - low Component: Installation and upgrade (command-line installer) Assignee: koha-bugs@lists.koha-community.org Reporter: giuseppe.ciaccio@unige.it QA Contact: testopia@bugs.koha-community.org Target Milestone: --- I'm trying to install Koha on a fresh Debian 9.7 32-bit, following the instructions at https://wiki.koha-community.org/wiki/Koha_on_Debian . I work as root so I have all privileges. One of the installation steps consists of editing file /etc/koha/koha-sites.conf . Inside koha-sites.con, I find the following row: USE_MEMCACHED="yes" 1.1) start memcached in the localhost (this action is not reported in the instructions but is needed): root@myhost:~# service memcached start 1.2) ensure that memcached is indeed active and listening at port 11211 root@myhost:~# ps ax PID TTY STAT TIME COMMAND ... 16908 ? S 0:00 /usr/sbin/apache2 -k start 16909 ? S 0:00 /usr/sbin/apache2 -k start 16910 ? S 0:00 /usr/sbin/apache2 -k start 16920 ? Ssl 0:00 /usr/bin/memcached -m 64 -p 11211 -u memcache -l 127. ... 1.3) proceed with install procedure, get worrying error messages root@myhost:~# koha-create --create-db mylibrary Koha instance is empty, no staff user created. [ ok ] Starting Koha indexing daemon for mylibrary:. root@myhost:~# koha-translate --install it-IT Connection to the memcached servers '__MEMCACHED_SERVERS__' failed. Are the unix socket permissions set properly? Is the host reachable? If you ignore this warning, you will face performance issues Connection to the memcached servers '__MEMCACHED_SERVERS__' failed. Are the unix socket permissions set properly? Is the host reachable? If you ignore this warning, you will face performance issues Use of uninitialized value $pref_name in concatenation (.) or string at /usr/share/koha/misc/translator/LangInstaller.pm line 197. Use of uninitialized value $pref_name in concatenation (.) or string at /usr/share/koha/misc/translator/LangInstaller.pm line 239. 1.4) at this point, try not to use memcached and repeat the koha-translate step, get same error as before root@myhost:~# vi /etc/koha/koha-sites.conf ...set USE_MEMCACHED="no" root@myhost:~# koha-translate --update it-IT Connection to the memcached servers '__MEMCACHED_SERVERS__' failed.

So it seems that I) the language installer tries to connect to memcached, no matter the value of USE_MEMCACHED II) the language installer fails to connect to memcached even if the daemon is up and listening to the right port. -- You are receiving this mail because: You are the assignee for the bug.
