This is the second part of my tutorial about how to install Pagekit CMS on CentOS 7.4.

In the previous tutorial, we have set up a LAMP stack and other required packages for Pagekit. In the second part of the tutorial, we will install Pagekit on our Alibaba Cloud Elastic Compute Service (ECS) instance.

But before doing that, we will need to configure our domain. We will also secure the domain with Let's Encrypt (SSL). After that, we will create a database and then finally install Pagekit CMS on our ECS instance.

Configure Domain

If you bought your domain from Alibaba Cloud, it will automatically set up DNS records. You will only be required to add the domain to Alibaba Cloud DNS. In this case, if you have already registered the domain from any other registrar, you will need to add that domain in Alibaba Cloud DNS and update its nameserver records on your registrar account. Once your DNS records are propagated, check them from intodns.com.

To setup domain name bought from a third party, follow the steps below:

1. Login to your Alibaba Cloud account and click on Alibaba Cloud DNS (available in left sidebar of your dashboard). Click Add Domain Name.
2. You will see a popup form. Now, type your complete domain name with TLD (in my case imarslan.com) and click Confirm.
3. Now your domain has been added to Alibaba Cloud DNS. You need to configure our domain. Click on Configure, right below the Add Domain Name button.
4. If you bought domain from Alibaba Cloud, your all nameservers would be configured already. If you bought it from some other registrar, Alibaba Cloud DNS configuration page will detect it and provide your information for changing nameservers.

1. Now add A record and its value will be the IP address of your ECS instance as shown below.

1. You can skip this step if you bought a domain from Alibaba Cloud. If you bought a domain from a third party, you will need to visit the domain registrar's website. The steps differ according to the registrar.
2. Now go back to Alibaba Cloud DNS page and click Add Record button to add records, after adding save them. To get records details, you can use intodns.com.

Create Virtual Host

1. Once your nameservers are updated, you can set up a virtual host to point your domain on your Alibaba Cloud ECS IP Address. To set up a virtual host on your ECS, execute the following command. Replace imarslan.com with your domain name. # sudo nano /etc/httpd/conf.d/imarslan.com.conf
   
2. Write or copy and paste the following text in the opened file. Replace imarslan.com and www.imarslan.com with your own domain name and itsaareez@example.com with your email address.

   <VirtualHost *:80>
     # Admin email, Server Name (domain name), and any aliases
     ServerAdmin itsaareez@example.com
     ServerName  imarslan.com
     ServerAlias www.imarslan.com
   
     # Index file and Document Root (where the public files are located)
     DirectoryIndex index.html index.php
     DocumentRoot /var/www/html/
     # Log file locations
     LogLevel warn
     ErrorLog  /var/www/html/error.log
     CustomLog /var/www/html/access.log combined
   </VirtualHost>

   After adding the text, use Ctrl + X, then press 'Y', then hit Enter key to save the file.
3. Now restart your Apache Server to load the changes by using the following command # sudo systemctl restart httpd
   
4. After setting up the virtual host, you can access your website by accessing your domain. In my case, I used www.imarslan.com to access my website. Note: The above configurations of the virtual host are for HTTP protocol. To set up an HTTPS protocol, you will have to install SSL. To install SSL and allow HTTPS to provide a secured experience to your users, you will need to install Let's Encrypt. Let's Encrypt will provide you free SSL for your domain.

Install Git

1. To begin installation of Let's Encrypt from GitHub repository, you will need to install Git. Execute the following command to install Git. # sudo yum install git
   
2. You will be asked "Is this ok?", enter 'y' and hit Enter key.

Configure Let's Encrypt SSL

1. For installation of Let's Encrypt SSL, you will have to stop your Apache Server. Use the command below to stop apache server. Remember, Certbot uses port 80 to get SSL certificate. Apache server uses same port 80. So, to avoid conflict, Apache server must be stopped until you get SSL certificate issued. # sudo systemctl stop httpd
   
2. You will get a clone of Let's Encrypt from official GitHub repository that will be installed in /opt/letsencrypt. To clone, type the following command and hit Enter. # sudo git clone https://github.com/letsencrypt/letsencrypt /opt/letsencrypt
   
3. Now navigate to /opt/letsencrypt by executing the command: # cd /opt/letsencrypt
   
4. Now create your SSL certificate. Let's Encrypt performs challenges for Domain Validation on the basis of which Certificate Authority (CA) will authenticate your domain. On validation, you will be issued a SSL certificate by CA. To create SSL certificate for your domain using Let's Encrypt, use the following command: # sudo -H ./letsencrypt-auto certonly --standalone -d imarslan.com -d www.imarslan.comNote: Remember to replace imarslan.com with your own domain name.
5. Now you will be prompted to write your email address. Type your email and hit Enter.
6. You will be asked to agree with terms. Type A and hit Enter to proceed.
7. Now when you will have to setup virtual host again to make it compatible with HTTPS. You will also want to stop people accessing your website without SSL. For this purpose, you may force SSL and every user will be redirected to secured website via HTTPS. For this purpose, execute the command below: # sudo nano /etc/httpd/conf.d/imarslan.com.conf
   
8. After executing the above command, a file will be opened. Copy the text below to this opened file.

   <IfModule mod_ssl.c>
       <VirtualHost *:443>
   
           ServerName imarslan.com
           ServerAdmin itsaareez@example.com
           ServerAlias www.imarslan.com
   
   
           SSLEngine on
           SSLCertificateFile /etc/letsencrypt/live/imarslan.com/cert.pem
           SSLCertificateKeyFile /etc/letsencrypt/live/imarslan.com/privkey.pem
           SSLCertificateChainFile /etc/letsencrypt/live/imarslan.com/chain.pem
   
   
           DirectoryIndex index.html index.php
            DocumentRoot /var/www/html/
            # Log file locations
           LogLevel warn
            ErrorLog  /var/www/html/error.log
           CustomLog /var/www/html/access.log combined
   
       </VirtualHost>
   </IfModule>
   
   <VirtualHost *:80>
     # Admin email, Server Name (domain name), and any aliases
     ServerAdmin itsaareez@example.com
     ServerName  imarslan.com
     ServerAlias www.imarslan.com
   
     Redirect permanent / https://www.imarslan.com/
     # Log file locations
     LogLevel warn
     ErrorLog  /var/www/html/error.log
     CustomLog /var/www/html/access.log combined
   </VirtualHost>

   Replace imarslan.com with your domain name. This above code will force SSL and all of the traffic will be redirected to HTTPS version of the website.

Create Database

1. Use MariaDB shell to login as root user and execute the following command: # sudo mysql -u root -p
   
2. Now the command prompt will ask you to enter password for user 'root'. Enter the password and hit enter key, you will be prompted to MariaDB command prompt.
3. To create the database and user for this database for your PageKit CMS, use the following query:

   CREATE DATABASE pk_db CHARACTER SET utf8 COLLATE utf8_general_ci;
   CREATE USER 'pk_db'@'localhost' IDENTIFIED BY 'SecurePassword';
   GRANT ALL PRIVILEGES ON pk_db.* TO 'pk_db'@'localhost';
   FLUSH PRIVILEGES;
   EXIT;

   where pk_db can be changed to your desired name.

Install PageKit CMS Files

1. To begin the installation of PageKit CMS, navigate to directory cd /var/www/html/because in Apache Server, we use this as web-directory. Note: In case, if you get any error like 'No such directory or file', then create htmldirectory. To do so, navigate to cd /var/www and execute the following command to create html directory and type cd html and hit enter. # sudo mkdir html
   
2. Now use the following command to get PageKit CMS package for installation. The following command will fetch the latest version of PageKit CMS from its official website. # sudo wget http://pagekit.com/api/download/latest -O pagekit.zip
   
3. Now you will have to list the files in the directory to see files & folders. To list the files in current directory, use the command: # ls -li

1. Downloaded PageKit CMS is saved in compressed form as pagekit.zip. Now you will have to unzip the compressed zip folder as listed when executed ls -li command. To do so, use the command: # sudo unzip pagekit.zip
   
2. Change the owner of files to avoid permissions issues. This will allow apache to access files of CMS without any issue. Execute command below: # sudo chown -R apache:apache /var/www/html
   
3. After performing the above steps, restart Apache to reload the latest configurations using the command: # sudo systemctl restart httpd
