[Tile-serving] renderd eroor

[Josef Schugt]

Hi,

IIRC that occurs when renderd.sock is not found; I had this issue, too.
So maybe my installation notes help (renderman is the user that I use
for tile generation stuff, software is installed under /usr/local rather
than /usr as I built everything from source). Note that that for some
odd reason I didn't manage to find, /run/renderd (or /var/run/renderd if
you are on an old system) vanishes at reboot.

## Run `renderd` in the Background

Apply the following changes to `~/src/mod_tile/debian/renderd.init`

Firstly change

    RUNASUSER=www-data

to

    RUNASUSER=renderman

secondly

    DAEMON=/usr/bin/$NAME

to

    DAEMON=/usr/local/bin/$NAME

thirdly

    DAEMON_ARGS=""

to

    DAEMON_ARGS="-c /usr/local/etc/renderd.conf"

forthly

    PIDSOCKDIR=/var/run/$NAME

to

    PIDSOCKDIR=/run/$NAME

and finally

    [ -r /etc/default/$NAME ] && . /etc/default/$NAME

to

    [ -r /usr/local/etc/$NAME ] && . /usr/local/etc/$NAME

After the block in which variables are initialized add

*    [ -d "$PIDSOCKDIR" ] || mkdir -p $PIDSOCKDIR && chown $RUNASUSER
$PIDSOCKDIR*

then copy the file to `/etc/init.d/renderd` and make that copy executable:

    sudo cp ~/src/mod_tile/debian/renderd.init /etc/init.d/renderd
    sudo chmod u+x /etc/init.d/renderd


then create `/lib/systemd/system/renderd.service` containing

    [Unit]
    Description=renderd
    After=multi-user.target
    Requires=multi-user.target
    
    [Service]
    Type=simple
    User=root
    PIDFile=/run/renderd/renderd.pid
    ExecStart=/etc/init.d/renderd start

    
    [Install]
    WantedBy=multi-user.target



make sure that `/run/renderd` exists and (including its contents) is
owned by
**renderman**

    sudo test -d /run/renderd || sudo mkdir /run/renderd
    sudo chown -R renderman /run/renderd

and finally

    sudo systemctl start renderd
    sudo systemctl enable renderd
    sudo systemctl restart apache2

Annuntio vobis gaudium magnum: habemus tile server. Let's set up a small
testing page for it. First we find out the region covered by our data,
then we
use Leaflet to show the map.

HTH,

Josef Schugt
