Mongod Service start exits with code 100
提问by Jankapunkt
Problem
问题
My mongo service does not start anymore:
我的 mongo 服务不再启动：
root@machine ~ # service mongod start
root@machine ~ # service mongod status
● mongod.service - High-performance, schema-free document-oriented database
Loaded: loaded (/lib/systemd/system/mongod.service; enabled; vendor preset: enabled)

Where exit code 100 is blurry defined as:
退出代码 100 的模糊定义为：
Returned by mongod when the process throws an uncaught exception.
当进程抛出未捕获的异常时由 mongod 返回。
What I did
我做了什么
First, I have installed my mongodb (3.4.7) on Ubuntu 16.04.2 LTS via the official guide.
首先，我已经通过官方指南在 Ubuntu 16.04.2 LTS 上安装了我的 mongodb (3.4.7) 。
Starting and stopping the service worked fine. So I continued to enable authentication (again via the official guide).
启动和停止服务工作正常。所以我继续启用身份验证（再次通过官方指南）。
Then I added the service to be able to run on server startup.
然后我添加了能够在服务器启动时运行的服务。
root@machine ~ # systemctl enable mongod.service
mongod.conf
mongod.conf
I also edited my config file, which is passed a yaml linter:
我还编辑了我的配置文件，它传递了一个 yaml linter：
# Where and how to store data.
storage:
dbPath: /var/lib/mongodb
journal:
enabled: true
# engine: mmapv1
# mmapv1:
# wiredTiger:
# where to write logging data.
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
# network interfaces
net:
port: 27017
bindIp: 127.0.0.1
#processManagement:
security:
authorization: enabled
The ownership of the file is
该文件的所有权是
root@machine ~ # ls -la /etc/ | grep mongo
-rw-r--r-- 1 root root 599 Aug 15 11:42 mongod.conf
DbPath
数据库路径
I know there are issues with the dbpath so this is what /var/lib/mongodbhas in terms of ownership:
我知道 dbpath 存在问题，所以这就是/var/lib/mongodb所有权方面的问题：
root@ machine ~ # ls -la /var/lib/ | grep mongo
drwxr-xr-x 4 mongodb mongodb 4096 Aug 15 11:54 mongodb
Service List
服务清单
When listing all services via service --status-allthere is no entry for any mongo related service.
通过列出所有服务时，service --status-all没有任何 mongo 相关服务的条目。
Somebody has a clue what could cause the issue?
有人知道可能导致问题的原因吗？
UPDATE
更新
As suggested I ran the following command (with a slight modification):
按照建议，我运行了以下命令（稍作修改）：
root@machine ~ /usr/bin/mongod --verbose --config /etc/mongod.conf &
[1] 28495
When I get it right, this is a direct execute of the binary. This allows me now to at least login into mongo shell:
当我做对了，这是二进制文件的直接执行。这让我现在至少可以登录到 mongo shell：
root@machine ~ # mongo
MongoDB shell version v3.4.7
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.4.7
>
However, the service status is still remaining failed with exit code 100.
但是，服务状态仍然保持失败，退出代码为 100。

You may still have some problems with the permissions in your data directory. Especially if you have run mongod from the terminal to start with.
您的数据目录中的权限可能仍然存在一些问题。特别是如果您从终端运行 mongod 开始。
I find that the data files are created under root not the mongodb user when you run from the terminal. To fix ..
我发现当您从终端运行时，数据文件是在 root 下创建的，而不是在 mongodb 用户下创建的。修理 ..

Try this!

Remove the mongod.lockfile under 'dbath', and it should start without issues.
删除 下的mongod.lock文件'dbath'，它应该可以正常启动。
