2. mongo유저로 구성,관리되도록 환경 구성

2.1. 유저,디렉터리 준비(root)

[root@testvm1 db]# useradd mongo
[root@testvm1 db]# passwd mongo

[root@testvm1 db]# mkdir /db/mongo
[root@testvm1 db]# mkdir /data1/mongo

[root@testvm1 db]# mv /etc/mongod.conf /db/mongo/
[root@testvm1 db]# chown -R mongo. /db/mongo
[root@testvm1 db]# chown -R mongo. /data1/mongo

2.2. configuration file 수정(mongo user)

[mongo@testvm1 ~]$ vi /db/mongo/mongod.conf
# mongod.conf

#where to log

logappend=true

# fork and run in background
fork=true

#port=27017

dbpath=/data1/mongo

# location of pidfile
pidfilepath=/db/mongo/mongod.pid

# Listen to local interface only. Comment out to listen on all interfaces.
#bind_ip=127.0.0.1

...

2.3 startup

[mongo@testvm1 journal]$ mongod -f /db/mongo/mongod.conf
about to fork child process, waiting until server is ready for connections.
forked process: 3894
child process started successfully, parent exiting

2.4 shutdown

[mongo@testvm1 journal]$ mongod -f /db/mongo/mongod.conf --shutdown
killing process with pid: 3894

3. 간단 CRUD

3.1 insert, select

[mongo@testvm1 db]$ mongo
MongoDB shell version: 2.6.9
connecting to: test
