Experimental thinking

The first step is installation and operation control.

Step 2 profile adjustment

The third step is status statistics and virtual host

The fourth step is LNMP construction

Step 5 LNMP platform deployment (launch) web application (website project)

two。 Experimental environment:

Overview of host OS IP address software description

Ctos6-1 Centos6.5 192.168.200.254 ftp and yum sources provide the underlying environment

Ctos6-2 Centos6.5 192.168.200.202 Nginx, mysql, php Nginx website

3. Key content:

Key content 1: what is nginx:

Lightweight HTTP service software, a web service software specially used to deal with static pages with stability, high efficiency, low consumption and high concurrent connection processing ability.

Key content 2: installation and operation control:

1. Download software-> install dependency packages (support software) to create users and groups-> install

two。 Operation control:

Nginx-t # # check the configuration

Nginx # # launch

Killall-s signal nginx # # signal has HUP overload configuration, QUIT exits, KILL kills

Key content 3: configuration file: / usr/local/nginx/conf/nginx.conf

1. Basic format:

Vi / usr/local/nginx/conf/nginx.conf

:% g / ^ $/ d # # Delete blank lines

:% g _

Configuration item format: key valu

Configuration includes: global configuration, events O event configuration (events {configuration item}), HTTP configuration (http {server {location {}}) http configuration can have multiple server configurations, server configuration can have multiple location configurations.

: wq

two。 Important configuration items:

Domain name of Server_name website

Location / {

Root html; # # the root directory of the website

Index index.html; # # specify the default home page

}

Key content 4: access status statistics and virtual hosts:

1. Access status: nginx built-in HTTP_STUB_STATUS module

Enabling this feature requires two steps: one is to compile and install is to specify-- with-http_stub_status_module, and the other is to modify the configuration file.

two。 Virtual hosts: nginx supports virtual hosts (port, ip, domain name)

1) nginx implements virtual host: one virtual host, one server {different listening address, domain name, port, log location, web page root directory}

2) commonly used virtual hosts are domain name-based virtual hosts. When configuring multiple virtual machines, you only need to add multiple domain name resolution and set multiple server {} configurations.

Key content 5: LNMP architecture and application deployment: nginx handles static pages, php-fpm deals with dynamic pages

1. Install MySQL database: compile, install, optimize, adjust, initialize the database to start the mysql service

two。 Install php: compile and install (note-- php-fpm enables php support) adjust to add zendguardloader after installation

3. Configure php-fpm (nginx supports php environment): first, create a php-fpm listening TCP/9000 port; second, add nginx to forward php requests to port 9000.

1) create a php-fpm configuration file:

Vi / usr/local/php5/etc/php-fpm.conf # # fpm configuration file

[global] # # Global configuration

Pid = run/php-fpm.pid

[www] # # website configuration

Listen = 127.0.0.1 9000 # # listening ip: Port

User = nginx # # user must be a user of the nginx process

Group = nginx

Pm = dynamic

Pm.max_children = 50 # # number of processes started at startup

Pm.start_servers= 20 # # minimum number of idle processes

Pm.min_spare_servers = 5 # # minimum number of idle processes

Pm.max_spare_servers = 35 # # maximum number of processes

: wq

2) configure nginx to support PHP parsing: choose one of the two ways

Method 1: proxy mode (forwarding php requests to other hosts that can resolve php) (used in the cluster)

Server {

Location ~ .php ${proxy_pass http://php parsing host ip: Port}

}

Method 2: call the php-fpm process (for stand-alone use)

Server {

Location ~ .php ${# # matches the request of php in URL

Root html; # # Web page root directory

Fastcgi_pass 127.0.0.1 9000; # # specify fpm snooping address and port

Fastcgi_index index.php; # # specify the php home page file

Include fastcgi.conf; # # introducing fastcgi.conf configuration

}

}

4. Publish php application (code online): download the program code (web page project) and extract and copy it to the root directory of the web page to create a database and authorize web page initialization and access.

three。 Project experiment steps (operation screenshot or operation command)

1. Installation and operation control:

1) install nginx:192.168.200.202
