Installing and anchoring NGINX, MySQL and PHP-PFM (CentOS, Red Hat)

To start we need to install the repository Atomic because this store is a PHP MySQL 5.4 and 5.5

Is it simply enough:
#wget-q-O-http://www.atomicorp.com/installers/atomic.sh | sh

Next set of MySQL (currently valid version 5.5, you can verify the command yum info mysql)

#yum install mysql * 5.5 *

Next put the PHP (currently valid version 5.4, you can verify the command yum info php)

#yum install php * 5.4 *

Next, put Nginx

#yum install nginx

Next put the handler php-fpm

#yum install php-fpm

Configure NGINX (/etc/nginx/nginx.conf):

user nginx;
worker_processes 1;

error_log/var/log/nginx/error.log;
PID/var/run/nginx.pid;

events {
worker_connections 2000;
}

http {

‘ “$request” $status $bytes _sent ‘
‘ “_referer” $http “$http _user_agent” ‘
“” $gzip _ratio “‘;

log_format download ‘ $remote _addr-$remote _user [$time _local] ‘
‘ “$request” $status $bytes _sent ‘
‘ “_referer” $http “$http _user_agent” ‘
“” $http “” $sent _http_content_range _range “‘;
