When you’re ready to get RainLoop installed on Ubuntu, follow the steps below:
Install Nginx HTTP Server
Nginx HTTP Server is probably the most popular web server, so install it since RainLoop needs it. To install Nginx HTTP on the Ubuntu server, run the commands below.
sudo apt update sudo apt install nginx
After installing Nginx, the commands below can be used to stop, start and enable the Nginx service to always start up with the server boots.
sudo systemctl stop nginx.service sudo systemctl start nginx.service sudo systemctl enable nginx.service
To test whether Nginx is installed, open your browser and browse to the server hostname or IP address. When you see that, then Nginx is working as expected.
http://localhost
Install PHP 7.2-FPM and Related Modules
PHP 7.2-FPM may not be available in Ubuntu default repositories. to install it; you will have to get it from third-party repositories.
Run the commands below to add the below third party repository to upgrade to PHP 7.2-FPM
sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php
Then update and upgrade to PHP 7.2-FPM
sudo apt update
Next, run the commands below to install PHP 7.2-FPM and related modules.
sudo apt install php7.2-fpm php7.2-common php7.2-curl php7.2-mbstring php7.2-xmlrpc php7.2-mysql php7.2-gd php7.2-xml php7.2-json php7.2-cli
After installing PHP 7.2, run the commands below to open Nginx’s PHP default config file.
sudo nano /etc/php/7.2/fpm/php.ini
Then make the changes on the following lines below in the file and save. The value below is an excellent setting to apply in your environment.
file_uploads = On allow_url_fopen = On short_open_tag = On memory_limit = 256M cgi.fix_pathinfo = 0 upload_max_filesize = 100M max_execution_time = 360 date.timezone = America/Chicago
After making the change above, save the file and closeout.
After installing PHP and related modules, you must restart Nginx to reload PHP configurations.
To restart Nginx, run the commands below
sudo systemctl restart nginx.service
To test PHP 7.2 settings with Nginx, create a phpinfo.php file in the Nginx root directory by running the commands below
sudo nano /var/www/html/phpinfo.php
Then type the content below and save the file.
<?php phpinfo( ); ?>
Save the file. Then browse to your server hostname followed by /phpinfo.php
http://localhost/phpinfo.php
You should see the PHP default test page.
Download and Configure RainLoop

After that, create the RainLoop directory and extract the download content there.
sudo mkdir /var/www/html/rainloop sudo unzip rainloop-community-latest.zip -d /var/www/html/rainloop
Next, configure the directory access permission for Nginx.
sudo chown -R www-data:www-data /var/www/html/rainloop/
sudo find /var/www/html/rainloop/ -type d -exec chmod 755 {} ;
sudo find /var/www/html/rainloop/ -type f -exec chmod 644 {} ;
When you’re done, run the commands below to create a rain loop Nginx configuration file.

root /var/www/html/rainloop;
index index.php index.html index.htm;
server_name example.com www.example.com;
client_max_body_size 100M;
location / {
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ^~ /data {

}
}
Save the file and exit.
Next, run the commands below to enable RainLoop virtual host and restart Nginx.
