Mercurial is a free, distributed source control management tool. This tutorial covers how to install Mercurial on the Mac OS and clone the Fab Academy archive.
You need to download and install Mercurial (there is an installer)l: http://mercurial.selenic.com/
You need to put key files (academy and academy.pub) where Mercurial can find them.
Open terminal (On Mac OS: from the Finder menu > Go > Utilities > Terminal)
You will be in your home directory by default. Your prompt with look something like::
MyComputerName:~ myhomedirectoryname$
Where "MyComputerName" is the name of your hard disk and the "myhomedirectoryname is the username you created to login to Mac OS.
Type the following text into the terminal after the prompt:
ls ~/.ssh
You system will ask you for a password - type in the password you use as an adminstrator on your Mac (this is the same password you use to log into your computer).
mkdir ~/.ssh
Within the .ssh directory you need to create another directory called keys.
To do this type:
mkdir ~/.ssh/keys
Download the keys that your instructor sent you in an email. They are named academy and academy.pub. You will need to place them in the keys directory. To do this, save the key files to your desktop from the email.
Change your location in the terminal by moving to the Desktop folder.
Type:
cd ~/Desktop
You need to move both of the keys from your desktop to the keys directory that you created earlier.
Type:
mv academy ~/.ssh/keysThen type:
mv academy.pub ~/.ssh/keys
Both keys are now located in the .ssh directory. You can check to see by typing: ls -l ~/.ssh/keys to list the contents of the directory. You should see that academy and academy.pub are listed.
You need to set permissions for your private key so that only you have read/write access to them.
Type:
chmod 600 ~/.ssh/keys/academy
chmod 644 ~/.ssh/keys/academy.pub
You will need to set the port that ssh uses to access fabacademy.org. You can do this by creating and editing a config file within your .ssh directory.
To open the file with the nano text editor, type:
nano config
The nano text editor will open in the terminal window.
Add the following text to the empty file:
host fabacademy.org port 846
To save the file:
- press [control]+O to save the file (then the enter key)
- press [control]+X to exit the editor
Do not add any extension to the file.
Now we need to move it to the .ssh directory.
Type:
mv config ~/.ssh/keys
Now we need to clone the archive for you region: na=North America, sa=South America, eu=Europe, as=Asia, af=Africa. Ask your Local Instructor or Remote Guru what archive to clone. In this example we are copying the North American (na) repository.
For convenience, we will clone it to the desktop.
Copy the text and paste it into the terminal:
hg clone -e "ssh -i ~/.ssh/keys/academy" ssh://hg@fabacademy.org/academy.2015/Web/na academy.2015
If you are cloning for the first time, you may be told that the "authenticity of the host cannot be established" and are given the option to type "yes" or "no".
Type "yes"
You should see the following response (or a similar response) in the terminal as the archive is cloned. Success!
requesting all changes adding changesets adding manifests adding file changes added 10 changesets with 119 changes to 112 files updating to branch default 111 files updated, 0 files merged, 0 files removed, 0 files unresolved
Next, clone the tutorials archive so you can edit and add to the tutorials as we go along. The tutorials are in the /doc archive:
hg clone -e "ssh -i ~/.ssh/keys/academy" ssh://hg@fabacademy.org/academy.2015/Web/doc academy.2015.tutorials
Now you need to edit your arcive's personal configuration file. To do this you need to move into the archive folder that you just created on the desktop. It is called academy.2015
Type:
cd academy.2015
You are now within the academy.2015 directory.
To edit your archive's personal configuration file (called hgrc) to reflect your name and email we need to open the file in a editior:
Type:
nano .hg/hgrc
A text editor will open inside of the terminal window. This text should already be in the file:
[paths]
default = ssh://hg@fabacademy.org/academy.2015/Web/na
[ui] username = First Last <user@machine.domain> ssh = ssh -p 846 -i ~/.ssh/keys/academy -C [hooks] changegroup = hg update >&2
To save the file:
- press [control]+O to save the file (then the enter key)
- press [control]+X to exit the editor
Now try updating your archive by typing:
hg pull
you should see a response like this:
pulling from ssh://hg@fabacademy.org/academy.2015/Web/na searching for changes no changes found
Congratulations! You have been successful and you can now work with the archive. Look over the Mercurial basics and resources page.
However, if you get a response like this:
pulling from ssh://hg@fabacademy.org/academy.2015/Web/na
searching for changes
adding changesets
adding manifests
adding file changes
added 1 changesets with 2 changes to 2 files
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
(run 'hg update' to get a working copy)
Type "hg update", now you are successful.
remote: ssh: connect to host fabacademy.org port 22: Connection refused abort: no suitable response from remote hg!
Then you forgot to edit the config file (see step 6)
