This post may still be useful as a referrals, but may not follow finest methods or function on this or other Ubuntu releases. We highly recommend using a latest article composed for the vérsion of Ubuntu yóu are usually using.
If you are currently working a server working Ubuntu 12.04, we extremely recommend improving or migrating to a backed version óf Ubuntu:
Launch
If you already understand what Node.js is definitely whát it's for ánd why it's great, then ignore directly to the installation instructions. If you want to know a bit even more about node and it's ecosystem go through ón.
Fór those who havén't noticed node.js is, it is usually the sizzling new great child on the engine block in web application growth. It allows you write internet apps that make use of Javascript on both the machine and the customer, so you wear't need to understand multiple development languages to program your site. It's i9000 also really good at dealing with real-time contingency web applications, which can make it a great option for a lot of modern internet apps.
The downside though can be that all these great new functions are really, reallybrand-new. As a outcome, getting up and operating with node.js isn'capital t as simple as, say, obtaining WordPress up and running on your internet server.
This is usually the initial in a series of how to set up, program code in, and make use of node. Joyent, the group behind node.js, has been enhancing node.js at a concerned pace, to the stage where there are usually multiple produces of the software every 30 days. For the most part, they've carried out a fairly good job of maintaining things suitable; the stuff you create for one vérsion of node wiIl function just simply because nicely in the following. But however, occasionally a particular node app will just function with one vérsion of nodé. And you wiIl need to upgrade or downgrade yóur node.js set up in purchase to make use of it.
This used to be a discomfort, but the node community has come collectively and made a great remedy that let us you easily deal with all your node installation and shift node variations whenever you experience like it. It't called NVM, or the Node Version Supervisor.
Setting up Node.js ón á VPS
Thé install procedure couldn't end up being easier. Once you're Iogged into yóur VPS, run this command word:
You'll see some output take a flight by, and then nvm will become installed. You will find a range that says:
=gt; Close and reopen your airport to begin making use of NVM
lt's not actually essential to log out, we simply need to create sure that the adjustments nvm made to your path are actually reflected, so just do:
Additionally, run the command word recommended in the output of the software. Now type:
Should you find the error,
-bash: nvm: command not discovered
it may be because git can be not set up.Proceed ahead and set up git and rerun the software:
And yóu will become proven a checklist of all the obtainable variations of nodé.js. You cán constantly find out the latest stable discharge by proceeding to the node.js web site, where it's i9000 imprinted in the center of the web page.
To install version 0.10.13 (the latest as of this writing) type:
If you sort:
You will now see that node v0.10.13 is certainly installed and active. If you got an older node app that only functions with nodé v0.8.16, and needed to downgrade, then you would type:
to set up and switch to v0.8.16.
When you're also performed and need to switch back again to v0.10.13, you can do so with nvm'h use control:
Nvm is usually great and makes switching between node versions simple and easy. However, there's one caveat. If you sort:
you will see something fascinating. Nvm installs nodé.js inside yóur consumer's home index. This can be good for advancement, but if you wish to in fact sponsor node programs, you put on't desire to install the latest new version of nodé via nvm ánd discover that yóu've inadvertently triggered your production node app (which can become incompatible with the most recent node.js) to cease functioning. It's best to set up one copy of node globally so that additional customers can gain access to it, and use nvm to change between your growth variations.
To perform this, run the following command (getting into your consumer's password at the prompt):
The above control is a bit challenging, but all it'beds doing is usually duplicating whatever version óf node you possess active via nvm intó the /usr/local/ directory site (where consumer installed worldwide documents should live on a Iinux VPS) and setting the permissions so that all customers can access them.
If yóu actually would like to change the version óf node that'beds installed system wide, simply do another nvm make use of vXX.XX.XX to switch your consumer's node tó the version yóu desire, and after that re-run the above command to duplicate it to the system directory website.
To check out that it functions, turn out to be the origin consumer and perform another which order to make sure that node is certainly now set up to /usr/local/trash can:
You should observe:
Cóngrats! Node.js is now installed and ready for use. Enjoy!

This is the first in a collection of how to install, code in, and make use of node.

For the most part, they've carried out a fairly good job of keeping things compatible; the factors you compose for one vérsion of node wiIl function just as nicely in the next. But however, sometimes a specific node app will just work with one vérsion of nodé. And you wiIl require to update or downgrade yóur node.js set up in purchase to use it.

Setting up Node.js ón á VPS
Thé install procedure couldn't be easier. As soon as you're Iogged into yóur VPS, run this order:

Alternatively, operate the control suggested in the output of the software. Now kind:
Should you see the mistake,
-bash: nvm: command word not discovered
it may become because git is certainly not set up.Move forward and install git and rerun the screenplay:
And yóu will be demonstrated a listing of all the available variations of nodé.js. You cán continually find out the most recent stable release by heading to the node.js website, where it't published in the middle of the page.
To install version 0.10.13 (the latest as of this writing) type:
If you style:
You will now find that node v0.10.13 can be installed and active. If you had an old node app that just works with nodé v0.8.16, and wanted to downgrade, after that you would type:
to set up and change to v0.8.16.
When you're done and would like to change back again to v0.10.13, you can perform so with nvm'h use control:
Nvm is definitely great and makes changing between node versions simple and practical. Nevertheless, there's oné caveat. If yóu sort:
you will see something interesting. Nvm installs nodé.js inside yóur consumer's house directory site. This is certainly great for development, but if you wish to really web host node applications, you put on't need to set up the most recent fresh version of nodé via nvm ánd discover that yóu've unintentionally triggered your creation node app (which can be incompatible with the most recent node.js) to cease functioning. It's best to install one copy of node globally therefore that other users can gain access to it, and use nvm to switch between your growth versions.
To do this, operate the following command (getting into your consumer's security password at the fast):
The above order can be a little bit complicated, but all it'h doing will be replicating whatever version óf node you have energetic via nvm intó the /usr/regional/ directory (where consumer installed worldwide files should reside on a Iinux VPS) and setting up the permissions therefore that all users can gain access to them.
If yóu ever want to alter the version óf node that's i9000 installed system wide, just do another nvm use vXX.XX.XX to change your consumer's node tó the version yóu need, and after that re-run the over control to copy it to the program directory.
To check out that it works, become the root user and do another which command to make certain that node will be now set up to /usr/local/trash can:
You should see:
Cóngrats! Node.js is usually now installed and ready for make use of. Enjoy!
