结果是
Starting mongod (via systemctl): Job failed. See system journal and 'systemctl status' for details. [FAILED]

How to install mongodb and mongodb-server on fedora linux (verified on f16 & f17). All commands are intended to be run in a su session.
如何在 fedora linux 上安装 mongodb 和 mongodb-server（在 f16 和 f17 上验证）。所有命令都旨在在 su 会话中运行。
1) make sure you have no mongodb installation lying around
1）确保你没有安装mongodb
# yum erase mongodb
# yum erase mongo-10gen (if it is installed)
2) install from fedora yum repository
2) 从 fedora yum 存储库安装
# yum --disablerepo=* --enablerepo=fedora,updates install mongodb mongodb-server
3) start mongod (mongodb daemon)
3）启动mongod（mongodb守护进程）
# systemctl start mongod.service
4) verify mongod is running
4) 验证 mongod 正在运行
# systemctl status mongod.service
# tail /var/log/mongodb/mongodb.log
# nmap -p27017 localhost
or running client
或运行客户端
# mongo
MongoDB shell version: 2.0.2
connecting to: test
> db.test.save( { a: 1 } )
> db.test.find()
{ "_id" : ObjectId("4fdf28f09d16204d66082fa3"), "a" : 1 }
5) customize configuration
5）自定义配置
# vim /etc/mongodb.conf
# systemctl restart mongod.service
6) make mongodb service automatically start at boot
6）让mongodb服务开机自动启动
# systemctl enable mongod.service
Update for Fedora 18
Fedora 18 更新
When started for the first time by systemd on a slow or loaded machine, mongod service might timeout before finishing its initialization, with systemd flagging the service as failed.
当 systemd 在缓慢或加载的机器上第一次启动时，mongod 服务可能会在完成初始化之前超时，systemd 会将服务标记为失败。
Symptoms:
症状：
# journalctl -xn
-- Unit mongod.service has begun starting up.
10:38:43 local mongod[24558]: forked process: 24560
10:38:43 local mongod[24558]: all output going to: /var/log/mongodb/mongodb.log
10:40:13 local systemd[1]: mongod.service operation timed out. Terminating.
10:40:13 local systemd[1]: Failed to start High-performance, schema-free document-oriented database.
-- Subject: Unit mongod.service has failed
Very easy cure, restart the service:
很容易治愈，重启服务：
# systemctl restart mongod.service
this should finish the initialization successfully and leave the daemon in running state.
这应该成功完成初始化并使守护程序处于运行状态。

I just had the same issue and in my case it was caused by installing mongodb following instructions of some websites using non-official repo. If you have the same issue and the answer above are not solving your problem, try uninstalling "mongodb-org" package and reinstalling it following the instructions of the official documentation : https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/
我刚刚遇到了同样的问题，在我的情况下，它是由使用非官方 repo 的某些网站的说明安装 mongodb 引起的。如果您有同样的问题并且上面的答案没有解决您的问题，请尝试按照官方文档的说明卸载“mongodb-org”包并重新安装：https: //docs.mongodb.com/manual/tutorial/install -mongodb-on-red-hat/
Remainder to uninstall package in fedora:
在 Fedora 中卸载软件包的剩余部分：
sudo dnf remove <package-name>
