nginx configuration and installation tutorial

Nginx ("engine Nginx is powered by Igor Sysoev was developed for the second most visited Rambler.ru site in Russia. The first public version 0.1.0 was released on 2004year10month4day. It releases its source code under a BSD-like license and is known for its stability, rich feature set, sample configuration files, and low system resource consumption. 2011year6month1day,nginx 1.0.4released. Generally we need to install

pcre and zlib

first, the former is for rewritingrewrite, and the latter is for

gzip

compression.

1.Select the source code directory Selected directory /usr/local/

cd /usr/local/

2.Install the PCRE

library

cd /usr/local/

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.21.tar.gz

tar -zxvf pcre-8.21.tar.gz

cd pcre-8.21

./configure

make

make install

3.Install the zlib

library

cd /usr/local/

wget http://zlib.net/zlib-1.2.8.tar.gz

tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8

./configure

make

make install

4.Install ssl

cd /usr/local/

wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz

tar -zxvf openssl-1.0.1c.tar.gz

./config

make

make install

5.Install nginx

Nginx generally has two versions, namely the stable version and the development version. You can choose one of these two versions according to your purpose. The following is to install Nginx

into the

/usr/local/nginx directory Detailed steps below:

cd /usr/local/

wget http://nginx.org/download/nginx-1.2.8.tar.gz

tar -zxvf nginx-1.2.8.tar.gz

cd nginx-1.2.8

./configure --prefix=/usr/local/nginx

make

make install

--with-pcre=/usr/src/pcre-8.21 refers to the source code path of pcre-8.21

.

--with-zlib=/usr/src/zlib-1.2.7

refers to the source code path of

zlib-1.2.7 .

6.Start

Make sure that the system’s

80 port is not occupied by other programs.

/usr/local/nginx/sbin/nginx

Check whether the startup is successful:

netstat -ano|grep 80

If the result is entered, it means the startup is successful

Open the browser to access the

IP of this machine. If the browser displays Welcome to nginx!

, it means that

Nginx has been installed and run successfully.

7.Restart

/usr/local/nginx/sbin/nginx –s reload

8.Modify configuration file

cd /usr/local/nginx/conf

vi nginx.conf

9.Common nginx configuration

#nginxRun user and group

user www www;

#Start process

, is usually set to be equal to the number of

cpu worker_processes 4;

#Global error log and PIDfile

pid /var/run/nginx.pid;

error_log /var/log/nginx/error.log;
