Tirex permissions problem

Question

I'm trying to run an instance of the OpenArdenneMap on my Ubuntu 16.04 server. The tirex systemd units run as user "osm", which also owns the pgsql database. Nevertheless I'm getting a permissions error.

/var/lib/mod_tile/ard is correctly owned by "osm" (and now even 777): drwxrwxrwx 2 osm osm 4096 Jun 25 01:22 .

Jun 25 01:55:28 host tirex-backend-manager[15979]: tirex-backend-mapnik[17153]: cannot add /etc/tirex/renderer/osm/osm.conf
Jun 25 01:55:28 host tirex-backend-mapnik[17153]: cannot add /etc/tirex/renderer/osm/osm.conf

Jun 25 01:55:28 host tirex-backend-manager[15979]: Cannot load any Mapnik styles

These are my tirex config files:

name=osm
tiledir=/var/lib/mod_tile/ard
maxz=18
fontdir=/usr/share/fonts/truetype
font_dir_recurse=1
mapfile=/home/osm/OpenArdenneMap/cartoCSS/OpenArdenneMap.xml

name=osm
path=/usr/lib/tirex/backends/mapnik
port=9331
procs=5
debug=1
plugindir=/usr/lib/mapnik/3.0/input
fontdir=/usr/share/fonts/truetype
fontdir_recurse=1

What have I overlooked?

----------------------------------- Edit ---

I've now changed the plugindir into plugindir=/usr/lib/mapnik/3.0/input but the error remains.

Answer 1

postgis.input is okay

Cannot open master UNIX domain socket: Permission denied
ls -la /usr/lib/mapnik/3.0/input/postgis.input 
-rwxr-xr-x 1 osm osm 253000 Dec  3  2015 /usr/lib/mapnik/3.0/input/postgis.input

The user is allowed to create the file /var/lib/tirex/modtile.sock

But still I'm getting this when running tirex-master:

Cannot open master UNIX domain socket: Permission denied

My server doesn't contain sensitive data: I would even be ready to give away my login to some expert!

Yes, this solved my issue.

I've then launched tirex-batch -p 50 map=osm bbox=5.9654,50.3627,9.514,52.5061 z=0,9

A few metatiles were generated, but most timed out:

Jun 25 17:52:33 host tirex-master[10737]: Job with id=1529937746_33410336 timed out on rendering list (map=osm z=0 x=0 y=0)
Jun 25 18:02:53 host tirex-master[10737]: Job with id=1529937746_36479432 timed out on rendering list (map=osm z=3 x=0 y=0)
Jun 25 18:02:53 host tirex-master[10737]: Job with id=1529937746_36454544 timed out on rendering list (map=osm z=2 x=0 y=0)

(The map still doesn't load in Leaflet.)

If you don't have fast disks you MUST increase the backend_manager_alive_timeout and master_rendering_timeout in tirex.conf (e.g. to 59 and 60 respectively). Also the syntax for zoom levels in tirex-batch is z=0-9 not z=0,9.
