This article mainly introduces the method of installing nodejs and realizing Nginx reverse proxy server under ubuntu, the content is detailed and easy to understand, the operation is simple and fast, and it has certain reference value. I believe you will get something after reading this article on the method of installing nodejs and realizing Nginx reverse proxy server under ubuntu. Let's take a look.

one。 New version of nodejs installation

Nvm (node version Manager) is highly recommended here, and other installations are more or less problematic.

The specific steps are as follows:

1. Download nvm through the git instruction

Execute the instructions as follows, and we download nvm to / root/git/ (remember to install git first):

[root@vm-22-180 vm-22 ubuntu] # vm-22 root [root @ vm-22-180 Murray ubuntu] # cd git [root @ vm-22-180 murubuntu] # git clone https://github.com/creationix/nvm.git

two。 Configure environment variables

Here is to modify the .bashrc file. If you don't know its location, you can go back to the root directory and execute it.

# find. -name "* .bashrc"-print

To search and get results:

Then modify the. / etc/skel/.bashrc file through vim (although I personally made the same changes in all three files above), adding the following two lines at the beginning of the file:

Export nvm_nodejs_org_mirror= https://npm.taobao.org/mirrors/nodesource ~ / git/nvm/nvm.sh

The first line is to modify the nvm image path to Ali, and the second line is to add nvm to the system environment.

Execute the instructions to make the configuration take effect after saving:

# source .bashrc

3. Install nodejs directly with nvm

Execute instruction

# nvm install node

You can install the new version of nodejs. After the installation is successful, the latest version of node is installed on the server:

two。 Install nginx

Like node, it is not recommended to install in the form of apt-get/aptitude. It is recommended to compile and install it with open source code.

1. Rely on installation and download

Ensure that gcc-c++ and libpcre3-dev are installed:

# aptitude install gcc-c++ libpcre3-dev

Then we navigate to / home/ubuntu to download some dependent packages and extract them to this folder:

# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.36.tar.gz#wget http://prdownloads.sourceforge.net/libpng/zlib-1.2.8.tar.gz#wget https://www.openssl.org/source/openssl-1.1.0c.tar.gz#tar-xzvf pcre-8.36.tar.gz#tar-xzvf zlib-1.2.8.tar.gz#tar-xzvf openssl-1.1.0c.tar.gz

Here we download the pcre/zlib/openssl that the nginx module depends on, and the download addresses of the compressed packages are found in their corresponding official websites.

It is important to note that pcre should not download anything that uses pcre2, otherwise it will cause an error in the nginx compilation process:

It is recommended to use the pcre-8.36 version provided in the above code snippet.

Note that if the download speed on the terminal is too slow, it is recommended to download it locally with Xunlei, and then synchronize the files to the CVM through filezilla.

two。 Download and extract nginx

First go to the nginx official website to find the latest source package download path (as of this article, the stable version is http://nginx.org/download/nginx-1.10.2.tar.gz), and then download it (I personally download it to the / root path):

[root@vm-22-180 Murubuntu] # CD [root @ vm-22-180MUBUUTU] # pwd/ root [root @ vm-22-180MUBUBUUTU] # wget http://nginx.org/download/nginx-1.10.2.tar.gz

Then extract the package and go to the folder / nginx-1.10.2:

[root@vm-22-180MUBUTU] # tar-xzvf nginx-1.10.2.tar.gz [root@vm-22-180MUBUBUTU] # cd nginx-1.10.2

3. Compile and install

Execute the following three instructions in order:

#. / configure-prefix=/home/ubuntu/nginx-with-pcre=/home/ubuntu/pcre-8.36-with-zlib=/home/ubuntu/zlib-1.2.8-with-openssl=/home/ubuntu/openssl-1.1.0c#make#make install

Their functions are to generate c source files and makefile files, generate binaries, and install nginx to a specified directory (/ home/ubuntu/nginx).

Note that the parameters after the. / configure directive specify the installation directory of nginx and the address of the related dependent modules, respectively.

three。 Start nginx

Execution

# / home/ubuntu/nginx/sbin/nginx

The nginx service can be started directly, which can be executed anywhere:

Wget http://127.0.0.1

Can be downloaded to an index.html:

At this point, we can directly access the public network ip address of the CVM and see the default page:

Be careful! If the page cannot be accessed through the public network ip, make sure that all ports are allowed to access the security group in which the CVM belongs.

four。 Execute a node service and implement a reverse proxy through nginx configuration

Here we simply implement a node page that listens to port 3000.

Let's write an index.js file locally to play with:

Const http = require ('http'); const server = http.createserver ((req, res) = > {res.statuscode = 200 content-type', res.setheader (' content-type', 'text/plain'); res.end (' hello world\ n');}); server.listen (3000, () = > {console.log (`setheader);})

If you execute node index, visiting http://localhost:3000/ will have the output of "hello world":

Then we put this file on the cloud host.

Since I'm already on github, readers can download the file directly with the following instructions:

# git clone https://github.com/vajoy/node-test.git

P.s. I personally downloaded it to the "/ root/node-project/" folder, and the instructions to execute node are:

# node / root/node-project/node-test/cp1/index

Ok, let's first modify the nginx configuration. If you forget where the nginx is configured, you can execute this instruction to determine:

# / home/ubuntu/nginx/sbin/nginx-t

The nginx for this article is installed under / home/ubuntu, so its configuration file path is "/ home/ubuntu/nginx/conf/nginx.conf". Let's edit it like this (plus the code in the red box):

This means that when a request path is "/ hello", nginx proxies the request to port 3000 of the server (that is, the port on which node listens).

five。 Restart nginx and node

Don't forget two things when you get to this point-- 1. We have not restarted the nginx service after modifying the nginx configuration; 2. We haven't run the node service on the cloud host yet (just once on the local computer above).

So we execute the following instructions respectively (restart nginx+ and run node):

# / home/ubuntu/nginx/sbin/nginx-s reload#node / root/node-project/node-test/cp1/index

At this point, you can directly see the content of the page that node is running when you directly visit the http:// public network ip/hello:
