Nginx is a web server. It can act as a reverse proxy server, as well as a load balancer and an HTTP cache. There was a need for an nginx reverse proxy (RP), so found a set of instructions that worked. However, after implementing those instructions, and getting everything configured, it was a determined a newer version of Nginx was required for additional configuration options. It turns out that the upgrade would be easier than expected. Hopefully, this guide will assist those whom may have already installed Nginx, but needed to upgrade it, without wanted to compile source.
This will install Nginx 1.0.15.
yum install -y epel-release yum install -y nginx chkconfig nginx on service nginx start lokkit -s http -s https
This will upgrade Nginx to 1.8.1.
cd /opt wget http://nginx.org/packages/centos/6/x86_64/RPMS/nginx-1.8.1-1.el6.ngx.x86_64.rpm yum update nginx-1.8.1-1.el6.ngx.x86_64.rpm
yum update http://nginx.org/packages/centos/6/x86_64/RPMS/nginx-1.8.1-1.el6.ngx.x86_64.rpm
When complete, check the version.
nginx -v nginx version: nginx/1.8.1
