kopano-search start up error

genesis74

did you try to connect to kopano-server via socket?

search.cfg:

server_socket = file:///var/run/kopano/server.sock

nickh

I’ve just tried enabling it and enabling server_pipe_name = /var/run/kopano/server.sock in server.cfg (which I assume had to be done at the same time) and then restarting but it made no difference.

check the rights on var/run/kopano/server.sock
i’ll bet its root:root and your running kopano:kopano

nickh

Everything in /var/run/kopano is kopano:kopano including server.sock and search.sock

Looking at the users I see:

[root@microserver ~]# kopano-cli --list-users
User list for Default (4):

I have only created 2, test1 and test3. Should the others (especially testusertestuser) be there?

Hi @nickh,

it’s been some time we discussed this topic. Did you solve your issue? If not, you might want to check if max_allowed_packet parameter in mysqld.cnf is increased as supposed in Kopano Wiki.

nickh

Unfortunately mine is already 32M.

genesis74

@nickh, is your kopano-server connecting to the mysql-server via TCP or socket?

nickh

TCP on port 3308 (non-standard) and it is a MariaDB server.

genesis74

@nickh, you could also try to connect to the database server via socket (i.e. in server.cfg: mysql_socket = /var/run/mysqld/mysqld.sock) if both are on the same machine. The combination of rising max_allowed_packet and using the mysql_socket solved the issue on my system (Ubuntu 18.04).

nickh

Brilliant. MariaDB is running in a sandbox on port 3308 and it means its socket file is different from standard (/var/lib/system-mysql/mysql.sock). That sorted it.

Thanks.

nickh

Hmm. It looks like it always happens if you stop/restart kopano-server while kopano-search is running. This means you have to stop kopano-search before stopping kopano-server and start it after starting kopano-server. This is not very workable.

Either the unit files need to be linked by dependencies or the two processes need to be run with a single command. It can be scripted but messy. For a condrestart you’d get something like:

#!/bin/sh

set SEARCH-RESTART=""
systemctl is-active kopano-search -q
if [ $? -eq 0 ]; then
    systemctl stop kopano-search
    set SEARCH-RESTART='yes'
fi
systemctl condrestart kopano-server
if [ -n "$SEARCH-RESTART" ]; then
    systemctl start kopano-search
fi

A restart would be similar.

I always do it that way because if I stop kopano-server I always get errors in search.log like (I cut the long part)

MAPI.Struct.MAPIErrorNotFound: MAPI error 8004010F (MAPI_E_NOT_FOUND)

I did not find any recommendation in the docs but I think kopano-server should always be the last to be stopped and the first to be startet (even though kopano-server logs

[error  ] Error while connecting to search on "file:///var/run/kopano/search.sock"

when kopano-search ist not running. Which is obvious ;-)
