# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
2.下载MongoDB 到/usr/loca/

# cd /usr/local/cd /usr/local/
# cd /usr/local/wgethttps://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.0.7.tgz
3.解压并创建数据库的存储及日志目录：

# tar -zxvf mongodb-linux-x86_64-rhel62-3.0.7.tgz
# mkdir -p mogodb/{data,logs}
# cd mogodb/
# ls
bindataGNU-AGPL-3.0logsREADMETHIRD-PARTY-NOTICES
# cd logs/
# touch mongodb.log
4.建立配置文件

# vi /usr/local/mongodb/bin/mongodb.conf
dbpath=/usr/local/mongodb/data
logpath=/usr/local/mongodb/logs/mongodb.log
port=27017
fork=true
nohttpinterface=true
5.启动MongoDB

# /usr/local/mongodb/bin/mongod --bind_ip localhost -f /usr/local/mongodb/bin/mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 1449
child process started successfully, parent exiting
6.设置开机自启动MongoDB

# echo "/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf"
/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf
7.测试：
(1)进入Mongodb的shell模式：

# ps -ef |grep mongo
root 1505 10 18:37 ? 00:00:03 /usr/local/mongodb/bin/mongod --bind_ip localhost -f /usr/local/mongodb/bin/mongodb.conf
root 1544 13240 18:45 pts/2 00:00:00 grep mongo
# kill 1505
注意：这个地方不能使用kill -9 pid，这样会导致数据丢失，同时mongodb还可能会报错。如果使用kill -9 pid的方式关闭mongodb，并且mongodb不能正常启动，则需删除mongod.lock文件
[root@test2 bin]# kill rm -rf /usr/local/mongodb/data/mongod.lock
[root@test2 bin]# /usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf
