IMPORTANT – At the writing of this post, this would only work on Ghost version 1.0.0.

Getting Started

Note that through out the document, I will stick to Ubuntu 18.04 OS version.

Step 01 — Install WordPress plugin that allow to back up the existing post metadata

• http://sitea.com/wp-admin -> plugins -> Add new
• Search “ghost”

Step 02 — Download the Ghost compatible JSON that has got the enough metadata 

• Tools -> Export to Ghost >
• Then click “Download Ghost File” and this will save a JSON containing all the metadata that required to spin up the equivalent Ghost instance.

Step 03 — Export Images that are part of the existing WordPress site.

• This step involves coping all the directory & files that are belongs to WEB site’s root Directory -> wp-content -> uploads. For example /var/www/html/siteA/wp-content/uploads/.
• To make a copy against all these data, you can use;
  • WInSCP from windows systems / SCP from Linux => SSH service should be running on the server that host the existing wordpress site.
  • FTP file transfer client => FTP service should be running on the server that host the existing wordpress site
  • Or check you cPannel options that probably support this.

Step 05 — Import the downloaded images into Ghost instance

• First, upload all the downloaded files & folders at step 03 into your new Ghost instances. These data should go under /var/www/ghostName/content/images/
• Now we need to make some changes to the Json that we downloaded in step02. Replace wp-content/uploads with content/images by executing the following command.
  # sed -i.bak -e ‘s|wp-content\\/uploads|content\\/images|g’ downloadGhostInstance.json
• Browse http://siteA.com/ghost/settings/labs/ and Click on “Choose File” and select the JSON file that we just updated, and click “Import“

Step 06 — Setting up the necessary permissions. 

# chown -R ghost:ghost /var/www/ghost/content/images

The post Migrate word-press site to Ghost instances appeared first on Linux Windows and android Tutorials.

Core areas that we will be working on:

• Make a copy of the existing Ghost instance and tweak some setting to host new blog
• Add additional VirtualHost on nginx to host the new domain – newblog.osradar.com
• Manage separate DB within MySQL to host the new blog
• Create systemD unit files to manage each blog

Getting Started

Note that through out the document, I will stick to Ubuntu 18.04 OS version.

# cd /var/www/
# cp -pr ghost ghost-new
# cd /var/www/ghost-new/system/files/
# mv blog.osradar.com.conf newblog.osradar.com.conf

Step 02 — Create new VirtualHost

# cd /etc/nginx/sites-available/
# ln -s /var/www/ghost-new/system/files/newblog.osradar.com.conf newblog.osradar.com.conf
# cd /etc/nginx/sites-enabled/
# ln -s /etc/nginx/sites-available/newblog.osradar.com.conf newblog.osradar.com.conf

# vim /etc/nginx/sites-enabled/newblog.osradar.com.conf

server {
    listen 80;
    listen [::]:80;

    server_name newblog.osradar.com;
    root /var/www/ghost-new/system/nginx-root;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://127.0.0.1:2369;
        
    }

    location ~ /.well-known {
        allow all;
    }

    client_max_body_size 50m;
}

Step 03 — Manage new MySQL DB

# mysql -uroot -p

mysql> create database new_blog_osradar;
mysql> GRANT ALL ON new_blog_osradar.* TO root@'localhost'
mysql> flush privileges;

new_blog_osradar => is a new database to host the new blog

# grep database /var/www/ghost/config.production.json

  "database": {
      "database": "ghost_production"

ghost_production => is the database name for the existing Ghost instance. Lets back it up and restore with the newly created DB.

# mysqldump -uroot -p --no-data ghost_production > backup.sql
# mysql -uroot -p new_blog_osradar<backup.sql

Lets change the  required configuration in the new instance of Ghost

# vim /var/www/ghost-new/config.production.json

{
  "url": "http://newblog.osradar.com",
  "server": {
    "port": 2369,
    "host": "127.0.0.1"
  },
  "database": {
    "client": "mysql",
    "connection": {
      "host": "localhost",
      "user": "root",
      "password": "password",
      "database": "new_blog_osradar"
    }
  },

Step 04 — Create new SystemD unit file

# cd /etc/systemd/system/
# cp ghost_blog-osradar-com.service ghost_newblog-osradar-com.service
# vim ghost_newblog-osradar-com.service

[Unit]
Description=Ghost systemd service for blog: newblog-osradar-com
Documentation=https://docs.ghost.org

[Service]
Type=simple
WorkingDirectory=/var/www/ghost-new
User=999
Environment="NODE_ENV=production"
ExecStart=/usr/local/bin/node /usr/local/bin/ghost run
Restart=always

[Install]
WantedBy=multi-user.target

That’s it. Now its all about setting up DNS records from different domains to map the single IP address that we have on our system. So, when browse from http://blog.osradar.com to http://newblog.osradar.com Nginx will take care the routing in between domains.

The post Multiple Ghost Instances on a Single Server appeared first on Linux Windows and android Tutorials.

What.?

Built on NodeJS, its a same kind of Content Management System as “WordPress”, but intention is more biased on blogs rather hosting common web site content. Ghost uses MySQL as a backend data store as does in WordPress, though when it comes to creating posts Ghost uses “Markdown” rather than visual WYSIWYG. Yes, both platforms are open source and free to download.

Getting Started

Note that through out the document, I will stick to Ubuntu 18.04 OS version.

Step 01 — Required Package Installation

# apt-get update

# apt-get install -y nginx mariadb-server

Step 02 — Create standard user which Ghost CMS can be used with

# useradd --home-dir /home/blog -m --shell /bin/bash blog

# usermod -aG sudo blog
# passwd blog

Step 03 — Modify mysql default configuration

# sudo mysql

MariaDB [(none)]> UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE user = 'root' AND plugin = 'unix_socket';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> exit

# sudo mysql_secure_installation

while going through the interactive mysql configuration, make sure to set the mysql root password.

Step 04 — NodeJS Installation

# curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash
# apt-get install -y nodejs

Optionally, you can install specific nodeJS version by

# apt-get install npm
# npm install n -g
# n latest or # n 6.9.1
# node -v

Step 05 — Ghost installation

Install ghost-cli

# sudo npm install ghost-cli@latest -g

OR need a specific version do;
# sudo npm install ghost-cli@1.0.0 -g

Create directory structure to host the Ghost instance

# sudo mkdir -p /var/www/ghost
# sudo chown blog.blog /var/www/ghost
# sudo chmod 775 /var/www/ghost

Install the ghost instance

# cd /var/www/ghost/
# ghost install
OR
# ghost install 1.0.0

? Enter your blog URL: https://blog.osradar.com
? Enter your MySQL hostname: localhost
? Enter your MySQL username: root
? Enter your MySQL password: [hidden]
? Enter your Ghost database name: ghost_prod
? Do you wish to set up "ghost" mysql user? Yes
? Do you wish to set up Nginx? Yes
? Do you wish to set up SSL? Yes
? Do you wish to set up Systemd? Yes
? Do you want to start Ghost? Yes

Step 06 — Make sure responsible daemons are up & running

# systemctl status mariadb.service
# systemctl status nginx.service
# systemctl status ghost_blog-osradar-com.service

In the up coming posts, I will be working on..

• Multiple Ghost environment on a single server
• Migrate word-press site to Ghost instances
