I get an error saying socket bind failed for: /var/run/renderd/renderd.sock if i am a regular user else everything works fine?

I am trying to manually build a map server as per instructions on switch2osm.org. I have configured everything. I have a database mayank owned by user mayank and I am trying to use renderd but i get this error socket bind failed for: /var/run/renderd/renderd.sock. Now if i switch to root and do the same it runs perfectly no direct permission issues because i have changed the owner for the directories recursively. But there might be some intermediate permission issues. I can not run it as root since I am using psql and my owner for the database mayank is my user mayank and this results in no tiles being renderd. And i don't want to reinstall my os but seriously understand the reason for this problem. Please help I am new to openstreetmaps and Linux. Below is the exact codes for my process:

mayank@DC050:~$ renderd
socket bind failed for: /var/run/renderd/renderd.sock
mayank@DC050:~$ sudo renderd
sudo: /var/lib/sudo owned by uid 1000, should be uid 0
[sudo] password for mayank: 
mayank@DC050:~$

Below is as root but no tiles are generated by this process probably because of the database thing

I came across almost the same problem you had. As far as i see there may be two causes behind this. Try run again with

sudo -u 'username' renderd -f -c /usr/local/etc/renderd.conf

after applying one of suggested solutions. Substitute 'username' for name of user running renderd:

Cause #1 missing writing rights

You probably have no writing rights to /var/run/renderd/renderd.sock file.

Solution for you would be changing owner of the directory :

sudo chown 'username' /var/run/renderd

and / or changing owner of the file by typing

sudo chown 'username' /var/run/renderd/renderd.sock

,where 'username' stands for user which will be runnning renderd.

Cause #2 missing directory

I have got almost identical error message as you.

In my case I was missing the /var/run/renderd directory. Solution in my case was creating /var/run/renderd directory and then changing its owner:

sudo mkdir /var/run/renderd
sudo chown 'username' /var/run/renderd

,where 'username' is user, which will be runnng renderd.
