Build NGINX+MYSQL+PHP-FPM site under Ubuntu

Overview

Nginx ("Engine X") is a high-performance HTTP and reverse proxy server, also a IMAP/POP3/SMTP proxy server. Nginx has the advantage of being able to handle a large number of static page requests with low memory efficiency.

You can refer to the following: three major web server comparison analysis (Apache, Lighttpd,nginx)

PHP-FPM is a patch written for the PHP kernel to handle the start, stop, and restart of fastcgi processes as needed. A bit is:

1. Low memory usage (because Nginx does not load the entire PHP environment when running alone).
2. Easily manage user permissions (because PHP can manage different users in your server process).
3. When PHP crashes, Nginx can run as usual.

NGINX+PHP-FPM can use less memory than apache+php_mod, carrying a high load.

installation

Installation of 1.nginx

wget Http://nginx.org/keys/nginx_signing.key
Apt-key Add Nginx_signing.key

echo "Deb http://nginx.org/packages/ubuntu/ trusty nginx" >>/etc/apt/sources.list

echo "Deb-src http://nginx.org/packages/ubuntu/ trusty nginx" >>/etc/apt/sources.list
Depending on the version of Ubuntu, Trusty will be replaced by other
Apt-get Update
Apt-get Install Nginx

If you have any questions, please refer to the official website documentation: Nginx installation method

The installation process encountered a problem

Chown:invalid group: ' Nginx:adm ', means no group ADM,Groupadd adm after apt-get install Nginx

Installation of 2.PHP-FPM

Apt-get Install PHP5-FPM

Netstat-anop

Indicates that the installed Nginx and PHP-FPM have been started

3. Modify Nginx and PHP-FPM configuration

Reference Zhang Daniel written Nginx 0.8.x + PHP 5.2.13 (FastCGI) build 10 times times more than Apache Web Server (6th edition)

Restart PHP-FPM and Nginx after configuration modification

Service PHP5-FPM Reload

Service Nginx Reload

Service PHP5-FPM Reload failed, so I ps-aux | grep PHP finds the PHP5-FPM process number, kills it, and then service PHP5-FPM start restarts FPM

After modifying the Nginx configuration, restart the error

Nginx: [Warn] the "log_format" directive May is used only on "HTTP" level in/etc/nginx/nginx.conf:84

"Log_format" misplaced location should not be placed on the server node, should be placed in the HTTP node, adjusted to restart the good

Installation of 4.mysql

Like Nginx and PHP5-FPM, the process is relatively smooth, not much talk

pressure test

Server configuration approximately Digitalocean vps,512m memory, stress test indicates that 800 concurrent can process 1888 requests per minute, 30 requests will fail

Also check server memory and CPU consumption, OK

Command reference:
