问题
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:~$
mayank@DC050:~$ renderd -f -c /usr/local/etc/renderd.conf

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

回答1:
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.
回答2:
Looks like there is a syntax error in your renderd.conf file. Just remove the trailing semicolon in renderd.conf at;[renderd02]
The Trailing semicolon suggests comments. So unless you have commented that out, there should not be a semicolon in front of it.
回答3:
All the tips I've found here are correct. But I needed also to replace in /usr/local/etc/renderd.conf this:
;** config options used by mod_tile, but not renderd **
into this:
;xxx=** config options used by mod_tile, but not renderd **
Looks like semicolon is treated as a comment, but the string that is after it still needs to apply to key=value formula, otherwise you get"
iniparser: syntax error in /usr/local/etc/renderd.conf
Or you may also remove that entire line (actually two lines, since it occurs there twice), since it is a comment anyway.
回答4:
it's permission error, just run:
renderd -f -c /usr/local/etc/renderd.conf
