Answer 1

step by step, centos 6.8

sudo kill $(sudo lsof -t -i:27017) 
rm -rf /tmp/mongodb-27017.sock
rm -f /var/lib/mongo/mongod.lock 
rm -f /var/run/mongodb/mongod.pid 
sudo service mongod start

open port 27017 and save changes

iptables -A INPUT -p tcp --dport 27017 -j ACCEPT
sudo service iptables sav
