mac上，用源码安装Leanote

Leanote是用go+Mongodb搭建的。
you could also use go getto download the Leanote package. As go get will call the git and mercurial commands, you need to install them first.
To Install git:
$> sudo apt-get install git-core mercurial openssh-server openssh-client
Then Fetch Revel, Leanote and related dependencies:
$> go get github.com/revel/cmd/revel
$> go get github.com/leanote/leanote/app
It may take a while to download these files, please be patient. The source code of Leanote is stored in /home/user1/gopackage/src/github.com/leanote/leanote.

Install Mongodb

Download Mongodb and configure

You could download a more up-to-date version from the official site of Mongodb. Or, you could use the following links to get the versions that are validated to be working by the developers.
Fast download:
Save the file to /home/user1, then extract it:
$> cd /home/user1
$> tar -xzvf mongodb-linux-x86_64-3.0.1.tgz/
To make sure that you can reference the Mongodb command from anywhere, configure its environment variable by adding the following line to your ~/bash_profile or /etc/profile (make sure you type in the correct username and version strings):
export PATH=$PATH:/home/user1/mongodb-linux-x86_64-3.0.1/bin
Again to make your modification take effect:
$> source /etc/profile

Test Mongodb installation

To verify the installation of Mongodb, make a new folder (e.g. data) under /home/user1 to store data:
$> mkdir /home/user1/data
Then start the Mongodb database server. You might want it to run in the background, so append & to the end:
$> mongod --dbpath /home/user1/data &
Now Mongodb is up and running, you can open a new terminal (or in the same terminal session if you have mongod run in the background) and launch it:
$> mongo
> show dbs
Should no error pops up, your Mongodb installation is complete, let's import initial data to Mongodb.

Import initial c data

Leanote's initial data is stored in /home/user1/gopackage/src/github.com/leanote/leanote/mongodb_backup/leanote_install_data
Open a terminal and paste in the following command to import initial data.
$> mongorestore -h localhost -d leanote --dir /home/$USER/gopackage/src/github.com/leanote/leanote/mongodb_backup/leanote_install_data/
Now Mongodb has created a leanote database, you can have a peek into it, for instance query how many tables leanote database has:
$> mongo
> show dbs 
leanote 0.203125GB
local 0.078125GB
Tell mongodb to use our newly created leanote database:
> use leanote 
switched to db leanote
Bit more playing around:
> show collections # a collection in Mongodb is a table in mysql
files
has_share_notes
note_content_histories
note_contents
notebooks
...
The initial users table has two accounts:
user1 username: admin, password: abc123 (administrator who can manage Leanote)
user2 username: demo@leanote.com, password: demo@leanote.com (just for demonstration)

Configure Leanote

The configuration of Leanote is controlled by this file: /home/user1/gopackage/src/github.com/leanote/leanote/conf/app.conf.
One setting that you are strongly suggested to modify is app.secret, please change arbitrary number of digits of the string to something different, but keeping the string length unchanged. This is to avoid potential security issues.
Other optional changes you can make includes db.username, db.password (more on these in the Trouble Shooting section) and etc..

Run Leanote

If you have successfully come to this stage, there is just one more step to go.
Make sure the Mongodb is still up and running, and your 9000 port (the default port, which can be changed later) is open. Then run:
$> revel run github.com/leanote/leanote
Note that if you are using revel 0.12 or above, please refer to this post
Congratulations, now fire up you browser and enter http://localhost:9000 (or http://IP_ADDRESS_OF_SERVER:9000) into the address bar. Voilà! Welcome to Leanote and happy note-taking!

Attention!

Please note that you run Mongodb with no auth option which mentioned in this paper, if your server is exposed to the internet, anyone can access and modify and delete it!!!!!! So it's very dangerous to run Mongodb in this way. You must add user and password to Mongodb and run it with auth option. Please see How to add new users to mongodb database?

Trouble shooting

If you encounter issues or want to know more about Leanote's configurations, refer to the FAQ page.
