Nginx is a very lightweight HTTP server written by Russians, Nginx, pronounced "engine X", is a high

Performance of HTTP and reverse proxy server, is also an IMAP/POP3/SMTP proxy server. Nginx is provided by

Russian Igor Sysoev developed for the second most visited Rambler.ru site in Russia.

Nginx is written in an event-driven (epoll) way, so it has very good performance and is also a very efficient inverse.

To agents, load balancing. However, Nginx does not support cgi mode, because it can reduce some of the programs it brings.

A loophole in the order. So you must use FastCGI to execute the PHP program.

Due to some advantages of Nginx itself, lightweight, open source and easy to use, more and more companies are using nginx as their own company.

Web application server, this article describes in detail the installation of nginx source code and optimizes the configuration of nginx.

I. Optimization of Nginx

1. Optimization before compilation and installation

Pre-compilation optimization is mainly used to modify the program name and so on, in order to change the source code hiding software name and version number.

Install dependent packages such as zlib-devel, pcre-devel, etc.

[root@bogon ~] # [root@bogon ~] # tar zxf nginx-1.14.0.tar.gz [root@bogon ~] # cd nginx-1.14.0/ [root@bogon nginx-1.14.0] # yum-y install openssl-devel pcre-devel

two。 Compile and install nginx

. / configure-- prefix=/usr/local/nginx1.14-- with-http_dav_module-- with-http_stub_status_module-- with-http_addition_module-- with-http_sub_module-- with-http_flv_module-- with-http_mp4_module-- with-pcre-- with-http_ssl_module-- with-http_gzip_static_module-- user=nginx-- group=nginxmake & & make install

3. Create the required users

[root@bogon nginx-1.14.0] # useradd nginx- s / sbin/nologin-M

4. Link command directory

[root@bogon nginx-1.14.0] # ln-s / usr/local/nginx1.14/sbin/nginx / usr/local/sbin/

5. Open nginx and view the port

Nginx

[root@bogon nginx-1.14.0] # netstat-anpt | grep 80

Tcp 0 0 0.0.0 0 master 80 0.0.0 0. 0. 0 master

6. Modify / usr/local/nginx1.14/conf/nginx.conf

7. Modify / etc/security/limits.conf

8. Check to see if it hasn't changed.

9. Log out and check again to see if it has changed.

10. Open nginx and check the changes of nginx

11. Visit nginx on the page

2. Deploy LNMP (deployment environment requirements: nginx and php are in one, and then another apache is enabled for hotlink protection)

1. Install php

Install libmcrypt and dependency packages first

Compile and install php

/ configure-- prefix=/usr/local/php5.6-- with-mysql=mysqlnd-- with-pdo-mysql=mysqlnd-- with-mysqli=mysqlnd-- with-openssl-- enable-fpm-- enable-sockets-- enable-sysvshm-- enable-mbstring-- with-freetype-dir-- with-jpeg-dir-- with-png-dir-- with-zlib-- with-libxml-dir=/usr-- enable-xml-- with-mhash-- with-mcrypt=/usr/local/ Libmcrypt-with-config-file-path=/etc-with-config-file-scan-dir=/etc/php.d-with-bz2-enable-maintainer-ztsmake & & make intall

Provide php profile

[root@bogon php-5.6.27] # cp php.ini-production / etc/php.ini

Provide scripts for php-fpm

Provide php-fpm configuration file and edit

Modify / usr/local/php5.6/etc/php-fpm.conf

Start php to view port 9000

/ etc/init.d/php-fpm start [root@bogon etc] # netstat-anpt | grep 9000tcp 00 0.0.0.0 netstat 9000 0.0.0.0 LISTEN

Modify / usr/local/nginx1.14/conf/nginx.conf

Create / usr/local/nginx1.14/html/index.php
