问题：按照官方指南所示安装了 Repo Here

启动 mongod 后出现冻结：

service mongod start
Starting mongod (via systemctl):

它像这样停止

添加日志信息

cat /var/log/mongo/mongod.log

运行过程：

ps aux | grep mongo

mongod   32320  0.2  0.2 451772 33772 ?        Sl   14:03   0:00 /usr/bin/mongod -f /etc/mongod.conf

我可以mongo在其他终端上运行，但是这个终端被冻结了，经过更长的时间我得到：

 service mongod start
Starting mongod (via systemctl):  Job for mongod.service failed. See 'systemctl status mongod.service' and 'journalctl -xn' for details.                                                          
                                                           [FAILED]

然后过程是这样的：

ps aux | grep mongo
root     15787  0.0  0.0 112664   928 pts/3    S+   14:10   0:00 grep --color=auto mongo
mongod   32320  0.2  0.2 452800 34316 ?        Sl   14:03   0:00 /usr/bin/mongod -f /etc/mongod.conf

但仍然可以使用mongo控制台。那failed部分呢？

journalctl -xn

正如其他答案已经说明的那样，问题是mongod.pidsystemd 在其他地方期望的文件。在软件包修复之前，我找到了解决这个问题的最佳方法，即更改 mongod 配置以在其中创建.pid文件/var/mongo（另一种可能性是更新 systemd 单元文件）。

首先，创建/var/mongo：

mkdir /var/mongo
chown mongod /var/mongo
chgrp mongod /var/mongo

像这样编辑/etc/mongod.conf和更新：

# location of pidfile
pidfilepath = /var/run/mongo/mongod.pid

确保mongod没有运行，现在它应该能够使用 systemctl 启动它：

systemctl start mongod

我发现了这个错误。这是 mongodb rpm 故障。Mongo 正在寻找，/var/run/mongo/mongod.pid路径是/var/run/mongodb/mongodb.pid. 希望他们能解决这个问题。至于现在在 fedora 18/19 中没有解决这个问题。

正如上面所说的

我发现了这个错误。这是 mongodb rpm 故障。Mongo 正在寻找 >/var/run/mongo/mongod.pid，路径是 /vat/run/mongodb/mongodb.pid。希望他们 > 会解决这个问题。至于现在在 fedora 18/19 中没有解决这个问题

所以你可以创建目录并以root身份/var/run/mongo复制到它：mongodb.pid

mkdir /var/run/mongo   
cp /var/run/mongodb/mongodb.pid /var/run/mongo/

我试过并且可以在 Fedora 19 中运行 mongodb
