Anchor CMS is a super-simple and extremely lightweight, free and open source Content Management System (CMS) Blog Engine that supports editing content in Markdown or HTML, and is fully i18n compatible out of the box. Creating and modifying themes is as easy as writing some very simple PHP and HTML/CSS, so there are no new templating languages to learn. Anchor CMS weighs in at only 250KB (compressed) so it is the perfect solution for web developers and bloggers who are tired of bloatware and just want a simple and minimalist blogging engine that gets the job done without any extra complications.

In this tutorial we are going to install Anchor CMS on a Debian 9 LAMP VPS using Apache web server, PHP 7.1, and a MariaDB database.

Prerequisites

• A clean Vultr Debian 9 server instance with SSH access

Step 1: Add a Sudo User

We will start by adding a new sudo user.

First, log into your server as root:

ssh root@YOUR_VULTR_IP_ADDRESS

The sudo command isn't installed by default in the Vultr Debain 9 server instance, so we will first install sudo:

apt-get -y install sudo

Now add a new user called user1 (or your preferred username):

adduser user1

When prompted, enter a secure and memorable password. You will also be prompted for your "Full Name" and some other details, but you can simply leave them blank by pressing Enter.

Now check the /etc/sudoers file to make sure that the sudoers group is enabled:

visudo

Meklējiet šādu sadaļu:

%sudo        ALL=(ALL:ALL)       ALL

Šī rinda mums norāda, ka lietotāji, kas ir grupas dalībnieki, sudovar izmantot sudokomandu, lai iegūtu rootprivilēģijas. Pēc noklusējuma tas netiks komentēts, lai jūs varētu vienkārši iziet no faila.

Tālāk mums ir nepieciešams, lai pievienotu user1pie sudogrupas:

usermod -aG sudo user1

Mēs varam pārbaudīt user1dalību grupā un pārbaudīt, vai usermodkomanda strādāja ar groupskomandu:

groups user1

Tagad izmantojiet sukomandu, lai pārslēgtos uz jauno sudo lietotāja user1kontu:

su - user1

Komandu uzvedne tiks atjaunināta, norādot, ka tagad esat pieteicies user1kontā. To var pārbaudīt ar whoamikomandu:

whoami

Tagad restartējiet sshdpakalpojumu, lai jūs varētu pieteikties, izmantojot sshjauno tikko izveidoto lietotāja kontu, kas nav root sudo:

sudo systemctl restart sshd

Exit the user1 account:

exit

Exit the root account (which will disconnect your ssh session):

exit

You can now ssh into the server instance from your local host using the new non-root sudo user user1 account:

ssh user1@YOUR_VULTR_IP_ADDRESS

If you want to execute sudo without having to type a password every time, then open the /etc/sudoers file again, using visudo:

sudo visudo

Edit the section for the sudo group so that it looks like this:

%sudo   ALL=(ALL) NOPASSWD: ALL

Please note: Disabling the password requirement for the sudo user is not a recommended practice, but it is included here as it can make server configuration much more convenient and less frustrating, especially during longer systems administration sessions. If you are concerned about the security implications, you can always revert the configuration change to the original after you finish your administration tasks.

Whenever you want to log into the root user account from within the sudo user account, you can use one of the following commands:

sudo -i
sudo su -

You can exit the root account and return back to your sudo user account any time by simply typing the following:

exit

Step 2: Update Debian 9 System

Before installing any packages on the Debian server instance, we will first update the system.

Pārliecinieties, vai esat pieteicies serverī, izmantojot sudo lietotāju, kas nav root lietotājs, un palaidiet šādas komandas:

sudo apt-get update
sudo apt-get -y upgrade

3. darbība. Instalējiet Apache tīmekļa serveri

Instalējiet Apache tīmekļa serveri:

sudo apt-get -y install apache2 

Pēc tam izmantojiet systemctlkomandu, lai palaistu un iespējotu Apache automātisku izpildi sāknēšanas laikā:

sudo systemctl enable apache2
sudo systemctl start apache2

Pārbaudiet savu Apache noklusējuma vietnes konfigurācijas failu, lai nodrošinātu, ka DocumentRootdirektīva norāda uz pareizo direktoriju:

sudo vi /etc/apache2/sites-enabled/000-default.conf 

DocumentRootKonfigurācijas opcija izskatīsies šādi:

DocumentRoot "/var/www/html"

Tagad mums ir jāiespējo mod_rewriteApache modulis, lai nodrošinātu, ka jūsu Apache noklusējuma vietnes konfigurācijas fails joprojām ir atvērts, un pievienojiet šādas DirectoryApache direktīvas tieši pirms noslēdzošā </VirtualHost>taga, lai jūsu konfigurācijas faila beigas izskatītos šādi:

    <Directory /var/www/html/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

Vissvarīgākā iepriekš norādītā direktīva ir AllowOverride All.

Now save and exit the file, and enable the mod_rewrite Apache module:

sudo a2enmod rewrite

We will restart Apache at the end of this tutorial, but restarting Apache regularly during installation and configuration is certainly a good habit, so let's do it now:

sudo systemctl restart apache2

Step 4: Install PHP 7.0

We can now install PHP 7.0 along with all of the necessary PHP modules required by Anchor CMS:

sudo apt-get -y install php php-gd php-mbstring php-common php-mysql php-imagick php-xml libapache2-mod-php php-curl php-tidy php-zip

Step 5: Install MariaDB (MySQL) Server

Debian 9 defaults to using MariaDB database server, which is an enhanced, fully open source, community developed, drop-in replacement for MySQL server.

Install MariaDB database server:

sudo apt-get -y install mariadb-server

Start and enable MariaDB server to execute automatically at boot time:

sudo systemctl enable mariadb
sudo systemctl start mariadb    

Secure your MariaDB server installation:

sudo mysql_secure_installation

The root password will be blank, so simply hit enter when prompted for the root password.

When prompted to create a MariaDB/MySQL root user, select "Y" (for yes) and then enter a secure root password. Simply answer "Y" to all of the other yes/no questions as the default suggestions are the most secure options.

Step 6: Create Database for Anchor CMS

Log into the MariaDB shell as the MariaDB root user by running the following command:

sudo mariadb -u root -p

To access the MariaDB command prompt, simply enter the MariaDB root password when prompted.

Run the following queries to create a MariaDB database and database user for Anchor CMS:

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

You can replace the database name anchor_db and username anchor_user with something more to your liking, if you prefer. Also, make sure that you replace "UltraSecurePassword" with an actually secure password.

Step 7: Install Anchor CMS Files

Change your current working directory to the default web directory:

cd /var/www/html/

If you get an error message saying something like 'No such file or directory' then try the following command:

cd /var/www/ ; sudo mkdir html ; cd html

Your current working directory should now be: /var/www/html/. You can check this with the pwd (print working directory) command:

pwd

Now use wget to download the Anchor CMS installation package:

sudo wget https://github.com/anchorcms/anchor-cms/archive/0.12.3a.zip

Please note: You should definitely check for the most recent version by visiting the Anchor CMS download page.

List the current directory to check that you have successfully downloaded the file:

ls -la

Remove index.html:

sudo rm index.html

Change ownership of the web files to avoid any permissions problems:

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

Restart Apache again:

sudo systemctl restart apache2

Step 8: Install and Run Composer

Anchor CMS requires us to use composer to download some plugins so we first need to install composer:

sudo apt-get -y install composer

Now make sure you are in the webroot directory:

cd /var/www/html

Run composer using the www-data user:

sudo -u www-data composer install -d /var/www/html/

You should see some warning messages from composer about not being able to write to the cache, but don't worry too much about that as everything should still install just fine.

We're now ready to move on to the final step.

Step 9: Complete Anchor CMS Installation

It's time to visit the IP address of your server instance in your browser, or if you've already configured your Vultr DNS settings (and given it enough time to propagate) you can simply visit your domain instead.

To access the Anchor CMS installation page, enter your Vultr instance IP address into your browser address bar, followed by /index.php:

http://YOUR_VULTR_IP_ADDRESS/index.php

Most of the installation options are self explanatory, but here are a few pointers to help you along:

1. On the Anchor CMS landing page, simply click on the Run the installer button to start the installation process.

2. Select your Language and Timezone and click on the Next Step button.

3. On the Database Details page, enter the following database values:

   Database Host:          localhost
   Port:                   3306
   Username:               anchor_user
   Password:               UltraSecurePassword
   Database Name:          anchor_db
   Table Prefix:           anchor_
   Collation:              utf8_unicode_ci
   

   Click Next Step to continue.

4. On the Site metadata page, enter the following details:

   Site Name:              <your site name>
   Site Description:       <a site description>
   Site Path:              /
   

   Click Next Step to continue.

5. Next enter appropriate admin login details:

   Username:               admin   
   Email Address:          <admin email address>
   Password:               <admin password>
   

6. Click on the Complete button to finalize the installation.

You will see a bright green page with the message Install complete!.

To access the admin section simply click on the Visit your admin panel button and enter your username and password. If you aren't redirected to the admin login page, you can enter the admin address manually:

http://YOUR_VULTR_IP_ADDRESS/admin/panel

For security reasons, make sure you delete the /install/ directory from the webroot directory:

sudo rm -rf ./install/

You are now ready to start adding your content and configuring the look and feel of your site. Make sure you check out the Anchor CMS documentation for more information about how to build and configure your site.
