1 Installing PHP 192.168.239.140/192.168.239.144

Do these preparations before installing (install the base environment)

yum-y Groupinstall "Development Tools" "Development Libraries"

Yum Install-y epel-release

Download PHP source package to/USR/LOCAL/SRC CD/USR/LOCAL/SRC

Unzip the CD directory Useradd-s/sbin/nologin php-fpm

Make && make install

CP php.ini-development/usr/local/php-fpm/etc/php.ini copy configuration file

CP SAPI/FPM/INIT.D.PHP-FPM/ETC/INIT.D/PHP-FPM Copy startup script

Mv/usr/local/php-fpm/etc/php-fpm.conf.default/usr/local/php-fpm/etc/php-fpm.conf

>/usr/local/php-fpm/etc/php-fpm.conf

Vim!$ Add the following configuration

[Global]

PID =/usr/local/php-fpm/var/run/php-fpm.pid
Error_log =/usr/local/php-fpm/var/log/php-fpm.log

[www]
Listen = 192.168.239.140:9000 (IP is php native IP or 0.0.0.0, cannot be 127.0.0.1)

chmod 755/etc/init.d/php-fpm

/ETC/INIT.D/PHP-FPM start NETSTAT-LNPT See if there is a listening 192.168.239.140:9000

Mkdir-p/tmp/tmp

vim/tmp/tmp/index.php Create the dynamic test file, write the following

Dongtaiqingqiu 1

2. The second installation of PHP (the installation and compilation are unchanged, the configuration file IP changed to 192.168.239.144:9000 last index.php Dongtaiqingqiu 1 to DONGTAIQINGQIU2)

3. Installing Nginx

Download source package to/usr/local/src CD/USR/LOCAL/SRC

wget http://nginx.org/download/nginx-1.6.2.tar.gz

Unzip the CD to extract the directory

Yum Install-y pcre-devel

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

Make

Make install

4. Writing Nginx Startup scripts

Vim/etc/init.d/nginx Add the following configuration

#!/bin/bash

# Chkconfig:-30 21

# Description:http Service.

# Source Function Library

. /etc/init.d/functions

# Nginx Settings

Nginx_sbin= "/usr/local/nginx/sbin/nginx"

nginx_conf= "/usr/local/nginx/conf/nginx.conf"

Nginx_pid= "/usr/local/nginx/logs/nginx.pid"

Retval=0

Prog= "Nginx"

Start () {

Echo-n $ "Starting $prog:"

Mkdir-p/dev/shm/nginx_temp

Daemon $NGINX _sbin-c $NGINX _conf

Retval=$?

Echo

Return $RETVAL

}

Stop () {

Echo-n $ "Stopping $prog:"

Killproc-p $NGINX _pid $NGINX _sbin-term

Rm-rf/dev/shm/nginx_temp

Retval=$?

Echo

Return $RETVAL

}

Reload () {

Echo-n $ "Reloading $prog:"

Killproc-p $NGINX _pid $NGINX _sbin-hup

Retval=$?

Echo

Return $RETVAL

}

Restart () {

Stop

Start

}

Configtest () {

$NGINX _sbin-c $NGINX _conf-t

return 0

}

Case "$" in

Start

Configtest)

Configtest

;;

*)

echo $ "Usage: $ {start|stop|reload|restart|configtest}"

Retval=1

Esac

Exit $RETVAL

After saving, execute

chmod A+x/etc/init.d/nginx or chmod 755! $ Modify Permissions

Service Nginx Start-up Nginx

5. Configuring the Reverse Proxy

>/usr/local/nginx/conf/nginx.conf

vim/usr/local/nginx/conf/nginx.conf Add the following configuration

User nobody nobody;

Worker_processes 2;

Error_log/usr/local/nginx/logs/nginx_error.log Crit;

Pid/usr/local/nginx/logs/nginx.pid;

Worker_rlimit_nofile 51200;

Events

{

Use Epoll;

Worker_connections 6000;

}

http

{

Include Mime.types;

Default_type Application/octet-stream;

Server_names_hash_bucket_size 3526;

Server_names_hash_max_size 4096;

Log_format combined_realip ' $remote _addr $http _x_forwarded_for [$time _local] '

Client_max_body_size 10m;

Client_body_buffer_size 256k;

Client_body_temp_path/usr/local/nginx/client_body_temp;

Proxy_temp_path/usr/local/nginx/proxy_temp;

Fastcgi_temp_path/usr/local/nginx/fastcgi_temp;

Fastcgi_intercept_errors on;

Tcp_nodelay on;

gzip on;

Gzip_min_length 1k;

Gzip_buffers 4 8k;

Gzip_comp_level 5;

Gzip_http_version 1.1;

Gzip_types text/plain application/x-javascript text/css text/htm application/xml;

Include vhosts/*.conf;

}

Configure agents

Mkdir/usr/local/nginx/conf/vhosts

vi/usr/local/nginx/conf/vhosts/php.conf Add the following configuration

Upstream Mysvr {

#weigth参数表示权值, the higher the weight, the greater the chance of being assigned.

Server 192.168.239.144:9000 weight=2;

Server 192.168.239.140:9000 weight=1;

}

Server

{

Listen 80;

server_name www.q.com;

Index index.html index.htm index.php;

root/usr/local/nginx/html;

Location ~ \.php$ {

Include Fastcgi_params;

Fastcgi_pass Mysvr;

Fastcgi_index index.php;

Fastcgi_param Script_filename/tmp/tmp$fastcgi_script_name;

}

}

/usr/local/nginx/sbin/nginx-t Detection configuration file

/usr/local/nginx/sbin/nginx-s Reload (direct reload configuration, no restart required)

vim/usr/local/nginx/html/1.html Create a static test file, write

Jingtaifangwen

Set Local resolution

Modify Windons hosts (address c:\windows\system32\drivers\etc\hosts) Notepad to open, add a line to the bottom of the configuration

192.168.239.136 www.q.com

Testing: It is best to use Google Chrome (shown below for agent success)

Access to the www.q.com display is the Nginx default page

Accessing the Jingtaifangwen displayed by www.q.com/.html

Access www.q.com/index.php multiple refreshes several times will show Dongtaifangwen1 once dongtaifangwen2 two times

Read this article there are any errors and do not understand, please leave a message, the landlord will promptly deal with, or contact qq:363138642, add reasons for the remarks, thank you!!!!!
