Following commands solved for cent os

 Error starting mongod. /var/run/mongodb/mongod.pid exists

FIXED BY:

   rm /var/lib/mongo/mongod.lock
   chown -R mongod:mongod /var/log/mongodb/
   chown -R mongod:mongod /var/run/mongodb/
   chown -R mongod:mongod /var/lib/mongo/
   chmod 777 /var/run/mongodb/mongod.pid

   mongod --dbpath /var/lib/mongo

Answer 3

We need to create the temp dir location of pidfile /var/run/mongodb that's handled by systemd-tmpfiles. So, create a file /lib/tmpfiles.d/mongodb.conf as root:

lnx#> sudo su
lnx#> cd /lib/tmpfiles.d
lnx#> echo “d /var/run/mongodb 0755 mongod mongod” > mongodb.conf

Then reboot or run this command to activate that temp directory:

lnx#>sudo systemd-tmpfiles --create mongodb.conf

Start mongod service:

lnx#> sudo systemctl start mongod.service

Answer 4

I was having the same problem running mongodb 3.0.4 on OpenSuse 13.2, and I found that the mongod directory under /var/run was missing. If I created the directory manually it would disappear after a reboot.

I solved it by adding the following lines to my /etc/init.d/mongod startup script:

mkdir -p /var/run/mongod  
chown $MONGO_USER:$MONGO_GROUP /var/run/mongod

What worked for me on Fedora 20: we need to create the temp dir on every boot, and that's handled by systemd-tmpfiles. So, create a file /lib/tmpfiles.d/mongodb.conf and put one line in it:

d /var/run/mongodb 0755 mongod mongod

That seems to handle it on restarts; if you don't want to restart right away, you can execute that with:

sudo systemd-tmpfiles --create mongodb.conf

(See the man pages for systemd-tmpfiles)
