Ok.... It is the small RAM problem again. SOLUTION:

free  
dd if=/dev/zero of=/var/swap.img bs=1024k count=1000  
mkswap /var/swap.img  
swapon /var/swap.img  
free

And then, install again:

# in case you've installed and failed
npm cache clean  
rm -rf /var/www/ghost/node_modules  
# install
npm install --production

Starting Ghost

# firewall setting
firewall-cmd --permanent --add-port=2368/tcp  
firewall-cmd --reload  
# configure
vim config.js  
# and change 'host' to '0.0.0.0'
# change 'url' to 'your-domain/blog'
# start
npm start --production

Deploy with Nginx and pm2(run forever)

install nginx first

yum install nginx -y  
# enable and start nginx
systemctl enable nginx.service  
systemctl start nginx.service

configure to listen port 80. Edit file /etc/nginx/conf.d/your-domain-name.conf:

server {  
    listen 80;
    server_name your-domain-name.com;
    location ^~ /blog {
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   Host      $http_host;
        proxy_pass         http://127.0.0.1:2368;
    }
}

restart nginx and open port 80 in firewall:

# firewall setting
firewall-cmd --permanent --add-service=http  
# if you don't need testing
# firewall-cmd --permanent --remove-port=2368/tcp
firewall-cmd --reload  
# restart 
systemctl restart nginx.service

run forever

# install pm2
npm install pm2 -g  
# run 
cd /var/www/ghost

Extra functions

Highlighting code blocks

PRISM.js Full-guide

First, download prism.js from the website (select your favourate languages =-=).

Place the files in the proper assets folders in your theme - content/themes/<theme-name>/assets/js/prism.js and content/thems/<theme-name>/assets/css/prism.css

Open content/themes/<theme-name>/default.hbs file and add <link> tag in the head for the style.

{{! Styles'n'Scripts }}
...
<link rel="stylesheet" type="text/css" href="{{asset "css/prism.css"}}" />  
...

and a <script> tag before the closing <body> tag

    ...
    <script type="text/javascript" src="{{asset "js/prism.js"}}"></script>
</body>

Then, you just need to restart you Ghost app.

LaTeX support

Use MathJax (CDN) .

Add a <script> tag before the closing tag

    ...
    <script type="text/javascript" src="//cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
</body>

Then, you just need to restart you Ghost app.
