Install LAMP Server<\/h2>\n
OSSN runs on the web server, written in PHP and uses MariaDB for the database. So, you will need to install Apache, PHP, and MariaDB to your system. OSSN does not support PHP 7.2 yet, so we will install PHP 7.1 from Ondrej repository.<\/p>\n
You can add the repository with the following command:<\/p>\n
sudo add-apt-repository ppa:ondrej\/php<\/code><\/pre>\nOnce the repository is added, install Apache, MariaDB, PHP, and all required PHP libraries by running the following command:<\/p>\n
sudo apt-get install apache2 mariadb-server php7.1 php7.1-mysql php7.1-curl php7.1-json php7.1-cgi libapache2-mod-php7.1 php7.1-mcrypt php7.1-xmlrpc php7.1-gd php7.1-mbstring php7.1 php7.1-common php7.1-xmlrpc php7.1-soap php7.1-xml php7.1-intl php7.1-cli php7.1-ldap php7.1-zip php7.1-readline php7.1-imap php7.1-tidy php7.1-recode php7.1-sq php7.1-intl wget unzip -y<\/code><\/pre>\nOnce all the packages are installed, start Apache and MariaDB service and enable them to start on boot time with the following command:<\/p>\n
sudo systemctl start apache2Configure Database<\/h2>\n
By default, MariaDB installation is not secured. You can secure it by running the following script:<\/p>\n
sudo mysql_secure_installation<\/code><\/pre>\nAnswer all the questions as shown below:<\/p>\n
Enter current password for root (enter for none): Set root password? [Y\/n]: N Remove anonymous users? [Y\/n]: Y Disallow root login remotely? [Y\/n]: Y Remove test database and access to it? [Y\/n]: Y Reload privilege tables now? [Y\/n]: Y \n<\/pre>\n
Once the MariaDB is secured, log in to MariaDB shell:<\/p>\n
mysql -u root -p<\/code><\/pre>\nEnter your root password and press Enter, then create a database and user with the following command:<\/p>\n
MariaDB [(none)]> CREATE DATABASE ossndb;Next, grant privileges to the OSSN database with the following command:<\/p>\n
MariaDB [(none)]> GRANT ALL PRIVILEGES ON ossndb.* TO 'ossn'@'localhost' IDENTIFIED BY 'password';<\/code><\/pre>\nReplace ‘password’ with a secure password in the above SQL command and note it down, we need it later during OSSN installation. Next, you will need to run the FLUSH PRIVILEGES command so that the privileges table will be reloaded by MySQL and we can use new credentia$<\/p>\n
MariaDB [(none)]> FLUSH PRIVILEGES;<\/code><\/pre>\nNext, exit from the MariaDB console with the following command:<\/p>\n
MariaDB [(none)]> EXIT;<\/code><\/pre>\nInstall OSSN<\/h2>\n
First, download the latest version of the OSSN with the following command:<\/p>\n
cd \/tmpAfter downloading, unzip the downloaded file with the following command:<\/p>\n
unzip build.zip<\/code><\/pre>\nNext, copy the extracted directory to the Apache root directory, create a data directory for OSSN and give proper permissions with the following command:<\/p>\n
sudo cp -r ossn \/var\/www\/html\/Next, create an Apache configuration file for OSSN with the following command:<\/p>\n
sudo nano \/etc\/apache2\/sites-available\/ossn.conf<\/code><\/pre>\nAdd the following lines:<\/p>\n
<VirtualHost *:80> ServerAdmin [email\u00a0protected]<\/a> DocumentRoot \/var\/www\/html\/ossn ServerName example.com \n <Directory \/var\/www\/html\/ossn\/> Options FollowSymlinks AllowOverride All Require all granted <\/Directory> \n ErrorLog ${APACHE_LOG_DIR}\/ossn_error.log CustomLog ${APACHE_LOG_DIR}\/ossn_access.log combined \n \n<\/VirtualHost> \n<\/pre>\n
Replace the domain name example.com with your own domain name. Save and close the file, then enable virtual host file and Apache rewrite module with the following command:<\/p>\n
sudo a2ensite ossn.confFinally, restart Apache to apply all the changes:<\/p>\n
sudo systemctl restart apache2<\/code><\/pre>\nOSSN will try to access itself by HTTP on the server to check mod_rewrite, this requires that the domain which you use for the installation in the virtual host file\u00a0\/etc\/apache2\/sites-available\/ossn.conf exists in DNS. If you are using a non-existing domain like I’ll do it here with example.com, then this domain needs to be configured in the \/etc\/hosts file of the server like this:<\/span><\/p>\n
nano \/etc\/hosts<\/span><\/code><\/pre>\nthe file should contain a line starting with the IP of the server, followed by the domain name. Example:<\/span><\/p>\n
192.168.1.100 example.com www.example.com<\/code><\/pre>\nSave the hosts file. Otherwise, you will get an error “MOD_REWRITE REQUIRED”.<\/p>\n
