Tor downloaded in centOS 7 but is failing to start and giving an error mesage that is "Failed to parse/validate config: Failed to bind one "
 

I added following repos in etc/yum.repos.d/tor.repo:

[Tor]
name=Tor Project Repo
baseurl=http://deb.torproject.org/torproject.org/rpm/el/6/$basearch/
gpgcheck=1
enabled=1
gpgkey=http://deb.torproject.org/torproject.org/rpm/RPM-GPG-KEY-torproject.org.asc

then i downloaded tor by:

[root@dhcppc29 tor]# yum install tor

it downloaded and installed successfully but it is not working and following is the output

Jan 20 18:14:01.224 [warn] Before Tor can create a control socket in "/run/tor/control", the directory "/run/tor" needs to exist, and to be accessible only by the user and group account that is running Tor. (On some Unix systems, anybody who can list a socket can connect to it, so Tor is being careful.)

Please help

This is the part that's relevant Did you start Tor as root? Start it as a regular user instead
