Install RainLoop in Arch Linux

Install RainLoop in Arch Linux

Once you have deployed Rainloop on your servers the only thing remaining to do is to access your Rainloop domain through a web browser and provide credentials for your enabled domain mail server.

This tutorial covers Rainloop webmail installation process on Arch Linux from both point of view configuration files for Apache and Nginx, using a virtual local domain configured through local hosts file, without a DNS server.

If you also need references on installing Rainloop on Debian and Red Hat systems visit the previous RainLoop Webmail article at.

  1. Install RainLoop Webmail on Debian and Red Hat based Systems

Requirements

For Nginx
  1. Install LEMP (Nginx, PHP, MySQL with MariaDB engine and PhpMyAdmin) in Arch Linux
  2. Create Virtual Hosts in Nginx Web Server
For Apache
  1. Install LAMP (Linux, Apache, MySQL/MariaDB, and PHP/PhpMyAdmin) in Arch Linux

Step 1: Create Virtual Hosts for Nginx or Apache

1. Assuming that you have configured your servers (Nginx or Apache) as described in upper presentations links, the first thing you need to do is to create a rudimentary DNS entry on local hosts file that points to Arch Linux system IP.

On Linux system edit /etc/hosts file and include your Rainloop virtual domain after localhost entry.

127.0.0.1	localhost.localdomain  localhost     rainloop.lan
192.168.1.33	rainloop.lan
Add Domain Host Entry

Add Domain Host Entry

On Windows system edit C:\Windows\System32\drivers\etc\hosts and add the following line at the bottom.

192.168.1.33       rainloop.lan

2. After you verify local domain using ping command, create the necessary Virtual Hosts and SSL configurations for Apache or Nginx.

Nginx Virtual Hosts

Create a file named rainloop.lan in /etc/nginx/sites-available/ path with the following configuration.

$ sudo nano /etc/nginx/sites-available/rainloop.conf

Add the following file content.

server {
    listen 80;
    server_name rainloop.lan;

    rewrite        ^ https://$server_name$request_uri? permanent;
    access_log /var/log/nginx/rainloop.lan.access.log;
    error_log /var/log/nginx/rainloop.lan.error.log;
    root /srv/www/rainloop/;

    # serve static files
    location ~ ^/(images|javascript|js|css|flash|media|static)/  {
     root    /srv/www/rainloop/;
     expires 30d;
    }

    location / {
        index index.html index.htm index.php;
                autoindex on;
                autoindex_exact_size off;
                autoindex_localtime on;
 }

 location ^~ /data {
  deny all;
}

    location ~ \.php$ {
        #fastcgi_pass 127.0.0.1:9000; (depending on your php-fpm socket configuration)
        fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
    }
 }

Then create the SSL equivalent file content.

$ sudo nano /etc/nginx/sites-available/rainloop-ssl.conf

Add the following file content.

server {
    listen 443 ssl;
    server_name rainloop.lan;

       ssl_certificate     /etc/nginx/ssl/rainloop.lan.crt;
       ssl_certificate_key  /etc/nginx/ssl/rainloop.lan.key;
       ssl_session_cache    shared:SSL:1m;
       ssl_session_timeout  5m;
       ssl_ciphers  HIGH:!aNULL:!MD5;
       ssl_prefer_server_ciphers  on;

    access_log /var/log/nginx/rainloop.lan.access.log;
    error_log /var/log/nginx/rainloop.lan.error.log;

   root /srv/www/rainloop/;

    # serve static files
    location ~ ^/(images|javascript|js|css|flash|media|static)/  {
      root    /srv/www/rainloop/;
      expires 30d;
    }

location ^~ /data {
  deny all;
}

    location / {
        index index.html index.htm index.php;
                autoindex on;
                autoindex_exact_size off;
                autoindex_localtime on;
 }

    location ~ \.php$ {
        #fastcgi_pass 127.0.0.1:9000; (depending on your php-fpm socket configuration)
        fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
    }
 }

On the next step generate Certificate file and Keys for SSL Virtual Host and add your virtual domain name (rainloop.lan) on Certificate Common Name.

$ sudo nginx_gen_ssl.sh
Generate Certificate and Keys

Generate Certificate and Keys

After the Certificate and SSL keys are generated, create Rainloop root webserver file path ( place where Rainloop PHP files reside), then enable Virtual Hosts and restart Nginx daemon to apply configurations.

$ sudo mkdir -p /srv/www/rainloop
$ sudo n2ensite rainloop
$ sudo n2ensite rainloop-ssl
$ sudo systemctl restart nginx
Create RainLoop Web Director

Create RainLoop Web Director

Apache Virtual Hosts

Create a new file named rainloop.conf in /etc/httpd/conf/sites-available/ with the following content.

$ sudo nano /etc/httpd/conf/sites-available/rainloop.conf

Add the following file content.

<VirtualHost *:80>
                ServerName rainloop.lan
                DocumentRoot "/srv/www/rainloop/"
                ServerAdmin you@example.com
                ErrorLog "/var/log/httpd/rainloop-error_log"
                TransferLog "/var/log/httpd/rainloop-access_log"

<Directory />
    Options +Indexes +FollowSymLinks +ExecCGI
    AllowOverride All
    Order deny,allow
    Allow from all
Require all granted
</Directory>

</VirtualHost>
Create Apache Virtual Host

Create Apache Virtual Host

Then create the SSL equivalent file content for Apache.

$ sudo nano /etc/httpd/conf/sites-available/rainloop-ssl.conf

Add the following file content.

<VirtualHost *:443>
                ServerName rainloop.lan
                DocumentRoot "/srv/www/rainloop/"
                ServerAdmin you@example.com
                ErrorLog "/var/log/httpd/rainloop-ssl-error_log"
                TransferLog "/var/log/httpd/rainloop-ssl-access_log"

SSLEngine on
SSLCertificateFile "/etc/httpd/conf/ssl/rainloop.lan.crt"
SSLCertificateKeyFile "/etc/httpd/conf/ssl/rainloop.lan.key"

<FilesMatch "\.(cgi|shtml|phtml|php)$">
    SSLOptions +StdEnvVars
</FilesMatch>

BrowserMatch "MSIE [2-5]" \
         nokeepalive ssl-unclean-shutdown \
         downgrade-1.0 force-response-1.0

CustomLog "/var/log/httpd/ssl_request_log" \
          "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %b"

<Directory />
    Options +Indexes +FollowSymLinks +ExecCGI
    AllowOverride All
    Order deny,allow
    Allow from all
Require all granted
</Directory>

</VirtualHost>

The next step is to create SSL Certificate file and Keys for SSL Virtual Host and add put your virtual domain name (rainloop.lan) on Certificate Common Name.

$ sudo apache_gen_ssl
Create SSL Certificate and Keys

Create SSL Certificate and Keys

Enter Organization Details

Enter Organization Details

After the Certificate and SSL keys are created, add Rainloop DocumentRoot path, then enable Virtual Hosts and restart Apache daemon to apply configurations.

$ sudo mkdir -p /srv/www/rainloop
$ sudo a2ensite rainloop
$ sudo a2ensite rainloop-ssl
$ sudo systemctl restart httpd
Enable Virtual Hosts

Enable Virtual Hosts

Step 2: Add necessary PHP Extensions

3. Whether you are using Apache or Nginx webserver, you need to enable the following PHP extensions on php.ini file and, also, include the new webserver DocumentRoot path to open_basedir directive.

$ sudo nano /etc/php/php.ini

Locate and uncomment the following PHP extensions.

extension=iconv.so
extension=imap.so
extension=mcrypt.so
extension=mssql.so
extension=mysqli.so
extension=openssl.so ( enables IMAPS and SMTP SSL protocols on mail servers)
extension=pdo_mysql.so

Also open_basedir statement should look like this.

open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/:/etc/webapps/:/srv/www/

4. After the php.ini file was modified restart your server than check phpinfo file to see if SSL protocols are enabled.

----------On Apache Web Server----------
$ sudo systemctl restart httpd
----------On Nginx Web Server----------
$ sudo systemctl restart nginx
$ sudo systemctl restart php-fpm
Check PHP Information

Check PHP Information

Step 3: Download and Install RainLoop Webmail

5. Now it’s time to download and extract Rainloop application from official website to Document Root directory but first install wget and unzip system utilities.

$ sudo pacman -S unzip wget

6. Download latest source package Rainloop zip archive using wget command or by using a browser to navigate to http://rainloop.net/downloads/.

$ wget http://repository.rainloop.net/v1/rainloop-latest.zip
Download RainLoop Package

Download RainLoop Package

7. After the download process finishes, extract Rainloop archive to Virtual Host Document Root path ( /srv/www/rainloop/ ).

$ sudo unzip rainloop-latest.zip -d  /srv/www/rainloop/
Extract Rainloop Archive

Extract Rainloop Archive

8. Then set the following permissions on application default path.

$ sudo chmod -R 755 /srv/www/rainloop/
$ sudo chown -R http:http /srv/www/rainloop/
Set Permission on RainLoop

Set Permission on RainLoop

Step 4: Configure Rainloop via Web Interface

9. Rainloop application can be configured in two ways: using a system shell of via browser. If you want to configure over terminal open and edit application.ini file located in /srv/www/rainloop/data/_data_da047852f16d2bc7352b24240a2f1599/_default_/configs/.

10. To access Admin Interface from browser, use the following URL address https://rainloop.lan/?admin, then provide the default application credentials.

User= admin
Password= 12345
Rainloop Web Interface

12. If you want to enable contacts login to MySQL database and create a new database with a privileged user on it, then provide database credentials on Contacts fields.

mysql -u root -p
create database if not exists rainloop;
create user rainloop_user@localhost identified by “password”;
grant all privileges on rainloop.* to rainloop_user@localhost;
flush privileges;
exit;
Enable Contacts in RainLoop

Enable Contacts in RainLoop

Enter Contact Database Details

Enter Contact Database Details

13. By default Rainloop provides Gmail, Yahoo and Outlook domains mail server configuration files, but you can add other mail server domains if you like.

For further configurations please visit official Rainloop documentation page at http://rainloop.net/docs/.

With Rainloop you can access mail servers from any device that has a browser as long as your server has Internet connectivity, the only minus of using Rainloop application in Arch Linux so far is the lack of poppassd plugin package needed to change email account password.
