Now, you need to install PHP by making use of the following command.

root@linuxhelp1 /etc # eopkg install php -y
Following packages will be installed:
imap  libmcrypt  libzip  php  tidy-html5
Total size of package(s): 11.48 MB

 [✓] Updating manpages database                                         success

Once it is installed, you need to start the PHP FPM service in the following manner.

root@linuxhelp1 /etc # systemctl start php-fpm

And then, create PHP configuration file as follows.

root@linuxhelp1 /etc # vim /etc/httpd/conf.d/php.conf
And add the following to configure the file. 
[..]
LoadModule proxy_module lib64/httpd/mod_proxy.so
LoadModule proxy_fcgi_module lib64/httpd/mod_proxy_fcgi.so
< FilesMatch .php$> 
SetHandler " proxy:fcgi://127.0.0.1:9000" 
< /FilesMatch> 
< IfModule dir_module> 
DirectoryIndex index.php index.html
< /IfModule> 
[..]

Once it is done, you need to enable the PHP-FPM service.

root@linuxhelp1 /etc # systemctl enable php-fpm

And then, you need to check the status of your PHP service.

root@linuxhelp1 /etc # systemctl status php-fpm
● php-fpm.service - The PHP FastCGI Process Manager
   Loaded: loaded (/usr/lib/systemd/system/php-fpm.service  enabled  vendor preset: enabled)
   Active: active (running) since Fri 2018-02-23 05:33:51 IST  2min 16s ago
 Main PID: 2889 (php-fpm)
   Status: " Processes active: 0, idle: 2, Requests: 0, slow: 0, Traffic: 0req/sec" 
    Tasks: 3 (limit: 7372)
   CGroup: /system.slice/php-fpm.service
           ├─2889 php-fpm: master process (/etc/php/php-fpm.conf)
           ├─2890 php-fpm: pool www
           └─2891 php-fpm: pool www

Now, you should create a PHP file, so run the following command.

root@linuxhelp1 /etc # vim /var/www/index.php
And add the following in it. 
[..]
Welcome to PHP
[..]

You should now restart the Apache service and PHP-FPM.

root@linuxhelp1 /etc # systemctl restart httpd
root@linuxhelp1 /etc # systemctl restart php-fpm

Now, open the browser.

Type local IP address with index.php

Go to the PHP page.

With this, the installation of LAMP on Solus 3 comes to an end.
