Adjust File permissions and ownership for extracted TaskBoard software files.

# chown -R apache:apache /var/www/html/taskboard
# chmod -R 775 /var/www/html/taskboard

Edit .htaccess file by using vim text editor.

# vi /var/www/html/taskboard/api/.htaccess

Locate and comment following four directives in this file.

#php_value upload_max_filesize 80M
#php_value post_max_size 100M
#php_value file_uploads On
#php_value memory_limit 256M

Create a Apache configuration file to deploy TaskBoard application. You can use vim text editor again.

# vi /etc/httpd/conf.d/taskboard.conf

Add following directives in this file.

<VirtualHost *:80>
    ServerAdmin admin@centlinux.com
    DocumentRoot "/var/www/html/taskboard"
    ServerName taskboard-01.centlinux.com
    <Directory "/var/www/html/taskboard">
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog "/var/log/httpd/taskboard-error_log"
    CustomLog "/var/log/httpd/taskboard-access_log" combined
</VirtualHost>

Test Apache configuration for any possible Syntax error.

# httpd -t
Syntax OK

Restart Apache service by using following command.

# systemctl restart httpd.service

Configure Linux Firewall for TaskBoard:

To make your TaskBoard application accessible across the network, you have to Allow http service in Linux firewall.

# firewall-cmd --permanent --add-service=http
success
# firewall-cmd --reload
success

Configure SELinux for TaskBoard:

For proper functioning of TaskBoard application, you have to allow write privileges in /var/www/html/taskboard/api directory.

Apache user already has the write privilege on api directory. But the SELinux is blocking it.

You can either Disable SELinux (not recommended) or you can add a SELinux fcontext to allow Apache user to write in this directory.

# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/taskboard/api(/.*)?'
# restorecon -RF /var/www/html/taskboard/api

Access TaskBoard Application:

Open URL http://taskboard-01.centlinux.com in a web browser.

You have reached at the dashboard of TaskBoard application.

Conclusion:

In this article, you have successfully installed TaskBoard software on CentOS / Red Hat Enterprise Linux (RHEL) 8.
