Deploying Wordpress

Setup Details

Container hostname: apache Network: 10.0.3.0/24 IP Address : 10.0.3.233 Subnet Mask: 255.255.255.0 Gateway: 10.0.3.1 DNS: 8.8.8.8 Container: Ubuntu 18.04 sudo user: kedar User PC Details PC type: Desktop OS: Ubuntu Desktop IP Address: 172.16.162.65 sudo user:kedar

SSH into the webserver

Webserver is a container having an ip adress of 10.0.3.233 and is a private IP address. This container is not reachable from any machine except the host server (infrabase1). To be able to access the webserver from any machine on the network that is able to reach the host (infrabase1) server, two things have been done

• For ssh access from User PC (Details mentioned in Infobox on the right, top corner), iptables have been used on host server (infrabase1) for port forwarding. The rule ensures that any request on the host (infrabase1 server), on port number 61300 will be port forwarded to 10.0.3.233 on port number 22.

sudo iptables -t nat -A PREROUTING -p tcp -i eno1 --dport 61300 -j DNAT --to-destination 10.0.3.233:22
sudo iptables -t nat -A PREROUTING -p tcp -i eno1 --dport 61301 -j DNAT --to-destination 10.0.3.137:22
sudo iptables-save
sudo service netfilter-persistent save

If an error is observed while executing the last two commands, install the below two packages and execute the above commands again

sudo apt install netfilter-persistent iptables-persistent

The second iptable rule is for port forwarding for the database server.

• For http access - This is required because wordpress sites will be served on port 80 on the webserver container. Nginx web server has been installed on host server (inrabase1) and is configured as a reverse proxy. This ensures that any port 80 request that hits the infrabase1 server will be redirected to the webserver container ip. Since the webserver container is running an apache webserver, depending on the header and configured virtual hosts, apache on webserver container will serve the necessary website. Nginx configuration as a reverse proxy can be found here.

Prep the webserver

• Log into the webserver. In this case the host name of the webserver is apache.

ssh kedar@10.0.3.233:61300
sudo apt install apache2 php7.2 php7.2-curl php7.2-gd php7.2-intl php7.2-json php7.2-mbstring php7.2-mysql php7.2-soap php7.2-xml php7.2-zip libapache2-mod-php7.2 rsync nano openssl
sudo systemctl status apache2

Database Creation

Assuming mariadb database has been installed on the db server (hostname is db1) run the following commands

sudo mysql -u root -p
CREATE DATABASE connect;
GRANT ALL PRIVILEGES ON connect.* TO "connect"@"%" IDENTIFIED BY "123456";
FLUSH PRIVILEGES;
quit;

Download Wordpress

wget https://wordpress.org/latest.tar.gz
tar -zxvf latest.tar.gz

Deploy Wordpress

• Create a folder in /var/www/html directory

cd /var/www/html
sudo mkdir connect

• Change the owner of the folder to be www-data

sudo chown -R www-data:www-data /data

• Create virtual host for the website

cd /etc/apache2/sites-available
sudo a2dissite 000-default.conf
sudo cp 000-default.conf connect.conf
sudo nano connect.conf

Add the below configuration in the connect.conf file

<VirtualHost connect.networked.com:80>
	ServerAdmin		admin@networked.com
	ServerName		connect.networked.com
	ServerAlias		connect
    DocumentRoot    /var/www/html/connect/

	ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
