After running the repair I was able to start the mongod proccessor but as root, which meant that service mongod start would not work. To repair this issue, I needed to make sure that all the files inside the database folder were owned and grouped to mongod. I did this by the following:

1. Check the file permissions inside your database folder
   1. note you need to be in your dbpath folder mine was /var/lib/mongo
      I went to cd /var/lib
   2. I ran ls -l mongo
2. This showed me that databases were owned by root, which is wrong. I ran the following to fix this: chown -R mongod:mongod mongo. This changed the owner and group of every file in the folder to mongod. (If using the mongodb package, chown -R mongodb:mongodb mongodb
   )

I hope this helps someone else in the future.

mongodb不能以服務方式正常啟動,而可以用shell的方式啟動的解決辦法
