I have installed mongodb and the PHP drivers on my UNIX server.
My question is how can I tell if mongodb is running? Is there a simple command-line query to check status? If I start it once from the shell will it keep running if I exit the shell (this doesn't seem to be the case)? How can I make the mongodb connection persistent and auto-start on server reboot?
I can run:
-bash-3.2$ su
Password:
[root@xxx]# cd /var/lib
[root@xxx]# ./mongodb-linux-i686-1.6.5/bin/mongod
./mongodb-linux-i686-1.6.5/bin/mongod --help
for help and startup options

If I open a seperate shell I can then then connect to mongodb:
-bash-3.2$ cd /var/lib
-bash-3.2$ ./mongodb-linux-i686-1.6.5/bin/mongo
MongoDB shell version: 1.6.5
connecting to: test
db.foo.find()
{ "_id" : ObjectId("4d63d7d3eb95985ab19c8feb"), "a" : 1 }
However if I close the initial shell I can't connect:
-bash-3.2$ cd /var/lib
-bash-3.2$ ./mongodb-linux-i686-1.6.5/bin/mongo
MongoDB shell version: 1.6.5
connecting to: test
