Apache web server installation is possible using the following command:

# pacman -S apache

Start the web server after each download:

# systemctl enable --now httpd

You must make sure that everything is working correctly. Go to http: //YOUR-SERVER-WEB-ADDRESS-OR-IP and you will see a page with an index / index. If you need to know your IP, run the command:

ip addr

The Apache configuration file is /etc/httpd/conf/httpd.conf. Although Apache is started by the root user, User http immediately switches to work on behalf of that user for security reasons. DocumentRoot “/srv/http” sets where it will search for web files. CustomLog “/var/log/httpd/access_log” common sets where Apache access, which is successful, will be logged. ErrorLog “/var/log/httpd / error_log” sets where access to Apache is that the error will be logged.

Disabling Indexes

If Apache is provided with a directory in which it does not find the index file with the extension that it has configured to use, it will automatically generate an index that shows the contents of the directory. To disable it, generate /etc/httpd/conf/httpd.conf., then inside <Directory “/srv/http”>, from Options, remove Indexes. After restarting, Apache will give you the following: “Access is denied!”. This error message appears if the file /srv/http/index.html does not exist.

Restart Apache

# systemctl restart httpd

Custom directories

By default, ~ /public_html/ the user directory will be shown at http: //YOUR-SERVER-WEB-ADDRESS-OR-IP/~ USERNAME/. But the http user must have executable bit access to the user’s directory and its public_html directory

$ mkdir ~/public_html
$ chmod o+x ~/
$ chmod o+x ~/public_html

Restart Apache

# systemctl restart httpd

Virtual Hosts

It is possible to host several domain names from one Apache web server at once and serve them with different content.
Create a folder to store your virtual host settings:

# mkdir /etc/httpd/conf/vhosts

Create a configuration file for each virtual host, for example /etc/httpd/conf/vhosts/YOUR-DOMAIN-NAME.com:

<VirtualHost *:80>
    ServerAdmin webmaster@YOUR-DOMAIN-NAME.com
    DocumentRoot "/srv/YOUR-DOMAIN-NAME.com"
    ServerName YOUR-DOMAIN-NAME.com
    ServerAlias YOUR-DOMAIN-NAME.com
    ErrorLog "/var/log/httpd/YOUR-DOMAIN-NAME.com-error_log"
    CustomLog "/var/log/httpd/YOUR-DOMAIN-NAME.com-access_log" common

    <Directory "/srv/YOUR-DOMAIN-NAME.com">
        Require all granted
    </Directory>
</VirtualHost>

Create a virtual host service directory:

# mkdir /srv/YOUR-DOMAIN-NAME.com

At the end of /etc/httpd/conf/httpd.conf., include each of these virtual host configuration files:

Include conf/vhosts/YOUR-DOMAIN-NAME.com

Restart Apache

# systemctl restart httpd

In order to install nginx you will need to enter the following command:

# pacman -S nginx-mainline

To start Nginx after each boot you need to enter:

# systemctl enable --now nginx

Then we check the functionality of Nginx. Visit http:// YOUR-SERVER-WEB-ADDRESS-OR-IP and you will see its welcome page. (Run ip addr if you need to know, find the IP address.)

Nginx configuration files are located in/etc/nginx, and its main file is nginx.conf. The string server.location.root/usr/share/nginx/html; sets where it will search for web files

Virtual host configuration

On a web server, you can host several domain names at once and serve them with different content and in different directions. You need to create a folder in order to store the settings of your virtual host

# mkdir /etc/nginx/sites-enabled

Next, you need to create a configuration file for each virtual host; Example: /etc/nginx/sites-enabled/EXAMPLE.COM and fill it with the following configuration:

server {
    listen 80;
    server_name EXAMPLE.COM;

    location / {
        root /usr/share/nginx/YOUR-DOMAIN-NAME.com;
        index  index.html index.htm;
    }
}

At the end of the http block /etc/nginx/nginx.conf, add the following line:

include sites-enabled/*;

Then you need to restart Nginx:

# systemctl restart nginx

Requests received by Nginx, EXAMPLE.COM will be processed by /usr/share/nginx/EXAMPLE.COM

Install Python 3.7 on your web server

On Nginx

To use Python 3.x (any version), you must enter the following:

# pacman -S uwsgi-plugin-python

Test python

In the appropriate test.py directory, the contents are listed below:

#-*- coding: utf-8 -*-
def wsgi_app(environment, start_response):
    import sys
    output = sys.version.encode('utf8')
    status = '200 OK'
    headers = [('Content-type', 'text/plain'),
               ('Content-Length', str(len(output)))]
    start_response(status, headers)
    yield output

application = wsgi_app

On Apache

Add /etc/httpd/conf/httpd.conf to the end or edit the corresponding configuration file and then add to the corresponding <VirtualHost> block:

WSGIScriptAlias /wsgi_app /srv/http/test.py

Restart Apache

# systemctl restart httpd

Follow the link in the browser http:// YOUR-SERVER-WEB-ADDRESS-OR-IP/wsgi_app and you can see a text page with all versions of Python and GCC.

Delete the test.py test file you just created and WSGIScriptAlias ​​in your Apache configuration.

On Nginx

Create the file /etc/uwsgi/wsgi_app.ini with the following contents:

[uwsgi]
socket = /run/uwsgi/wsgi_app.sock
uid = http
gid = http
plugins = python
chdir = /usr/share/nginx/html/
wsgi-file=test.py
callable = application

Start service uWSGI wsqi_app:

# systemctl start uwsgi@wsgi_app

You need to give Nginx permission to use uWSGI by editing /etc/nginx/nginx.conf, and for each server block that you want to test, add the following. Alternatively, if you use virtual hosts, edit the configuration file for each host:

location ~ \wsgi_app {
    root /usr/share/nginx/html/;
    include uwsgi_params;
    uwsgi_pass unix:/run/uwsgi/wsgi_app.sock;
}

Restart Nginx:

# systemctl restart nginx

Visit your web browser, http://YOUR-SERVER-WEB-ADDRESS-OR-IP/wsgi_app and you will see a test page with versions of Python and GCC.

Delete the test.py file you just created and the location block you just added /etc/nginx/nginx.conf to wsgi_app.

Restart Nginx

# systemctl restart nginx

Stop serving uWSGI wsgi_app:

# systemctl stop uwsgi@wsgi_app

In the final episode, you need to delete /etc/uwsgi/wsgi_app.ini, test files, who you created earlier.
