[How to]Install Nginx on Linux Centos 6.5 / 6.6


When this tutorial written, latest stable version of nginx is 1.6.2, and the latest nginx mainline version is 1.7.10. But, when it comes to centos, “If it ain’t broke, don’t fix it“, so I choose a stable one. Here is the code.

yum update -y
sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
cd /etc/yum.repos.d
curl -O http://rpms.famillecollet.com/enterprise/remi.repo

touch /etc/yum.repos.d/nginx.repo
echo "[nginx]" >> /etc/yum.repos.d/nginx.repo
echo "name=nginx repo" >> /etc/yum.repos.d/nginx.repo
echo "baseurl=http://nginx.org/packages/centos/6/\$basearch/" >> /etc/yum.repos.d/nginx.repo
echo "gpgcheck=0" >> /etc/yum.repos.d/nginx.repo
echo "enabled=1" >> /etc/yum.repos.d/nginx.repo

yum install -y nginx
service nginx restart

To make sure it’s installed :

..[$] <()> netstat -ntpl
Active Internet connections (only servers)

Right now I implement on Digitalocean (it has referral link) because it’s fast and easy to deploy, my favorite feature is snapshot. I usually using the smallest one ($5 / month), when it goes well in the smallest one, it will be better on the bigger one.

A few words on sailsjs awesome nodejs framework

Sailsjs make it easy to build custom, enterprise-grade Node.js apps.

So, recently I watch this video. And I think it is really worth to try, really awesome do everything that simple, like create a REST API, it use ORM.

I think I will use leafletjs, since it use openstreetmap. I’m still working on it, I will share when it’s done.

Here is the awesome video :
