搭建Nginx+PHP环境

一. 源码包编译安装部署web服务器

1.安装nginx必须的依赖包

[root@test01 ~]# yum -y install gcc openssl-devel pcre-devel zlib-devel

2.安装编译nginx，目前系统测试环境为CentOS6.3 软件版本为nginx-1.2.6

[root@test01 ~]# useradd nginx -s /sbin/nologin

[root@test01 ~]# tar zxvf nginx-1.2.6.tar.gz

[root@test01 ~]# cd nginx-1.2.6

[root@test01 nginx-1.2.6]# ./configure --user=nginx --group=nginx--prefix=/usr/local/nginx/ --with-http_stub_status_module--with-http_ssl_module

// --with-http_stub_status_module 安装允许状态模块

// --with-http_ssl_module 安装ssl模块

[root@test01 ~]# /usr/local/nginx/sbin/nginx -v //查看Nginx的相关环境配置信息是否正确

nginx version: nginx/1.2.6

[root@test01 ~]#

[root@test01 nginx-1.2.6]# make & make install //编译安装过程略

3.通过nginx自身脚本机器nginx服务器,并通过各种命令查看是否启动成功

[root@test01 ~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf // -c指向nginx主配置文件

[root@test01 ~]# lsof -i :80 //查看nginx进程号及运行情况

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

nginx 21910 root 9u IPv4 262148 0t0 TCP*:http (LISTEN)

nginx 21911 nginx 9u IPv4 262148 0t0 TCP*:http (LISTEN)

[root@test01 ~]# ps -ef | grep nginx //查看nginx进程号及运行情况

root 21910 1 0 10:41 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c/usr/local/nginx/conf/nginx.conf

nginx 21911 21910 0 10:41 ? 00:00:00 nginx:worker process

root 21957 21755 0 10:42 pts/0 00:00:00 grep nginx

[root@test01 ~]# netstat -nltp | grep 80 //查看nginx进程监听端口

[root@test01 ~]# netstat -an |grep 80

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

4.通过windows服务器IE浏览器测试

扩展知识:

1）设置nginx开机自动启动，将nginx启动命令添加到/etc/rc.local

[root@test01 ~]# echo "/usr/local/nginx/sbin/nginx -c/usr/local/nginx/conf/nginx.conf" >> /etc/rc.local

[root@test01 ~]# cat /etc/rc.local | grep nginx

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

2）通过设置System V 脚本，使用server命令启动nginx服务

[root@test01 init.d]# vim nginx //在/etc/init.d/下创建nginx启动脚本文件

#!/bin/sh

#

# nginx - this script starts and stops the nginx daemon

#

# chkconfig: - 85 15

# description: Nginx is an HTTP(S) server, HTTP(S) reverse \

# proxy and IMAP/POP3 proxy server

# processname: nginx

# config: /etc/nginx/nginx.conf

# config: /etc/sysconfig/nginx

# pidfile: /var/run/nginx.pid

# Source function library.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ "$NETWORKING" = "no" ] && exit 0

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

prog=$(basename $nginx)

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

[ -f /etc/sysconfig/nginx ] && ./etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

start() {

[ -x $nginx ] || exit 5

[ -f $NGINX_CONF_FILE ] || exit 6

echo -n $"Starting $prog: "

daemon $nginx -c $NGINX_CONF_FILE

retval=$?

echo

[ $retval -eq 0 ] && touch $lockfile

return $retval

}

stop() {

echo -n $"Stopping $prog: "

killproc $prog -QUIT

retval=$?

echo

[ $retval -eq 0 ] && rm -f $lockfile

return $retval

killall -9 nginx

}

restart() {

configtest || return $?

stop

sleep 1

start

}

reload() {

configtest || return $?

echo -n $"Reloading $prog: "

killproc $nginx -HUP

RETVAL=$?

echo

}

force_reload() {

restart

}

configtest() {

$nginx -t -c $NGINX_CONF_FILE

}

rh_status() {

status $prog

}

rh_status_q() {

rh_status >/dev/null 2>&1

}

case "$1" in

start)

rh_status_q && exit 0

;;

rh_status_q || exit 0

;;

;;

rh_status_q || exit 7

condrestart|try-restart)

echo $"Usage: $0{start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"

exit 2

esac

[root@test01 init.d]# chmod 755 nginx //修改脚本文件nginx的权限

[root@test01 init.d]# chkconfig --add nginx //将脚本文件加入chkconfig中

[root@test01 init.d]# chkconfig --level 35 nginx on //设置nginx开机在3和5级别自动启动

[root@test01 init.d]# chkconfig --list | grep nginx

nginx 0:off 1:off 2:off 3:on 4:off 5:on 6:off

测试nginx脚本文件是否能够正常使用

[root@test01 init.d]# /etc/init.d/nginx restart //重新启动

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

Stopping nginx: [ OK ]

Starting nginx: [ OK ]

[root@test01 init.d]# /etc/init.d/nginx reload //不间断服务平滑重启

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

Reloading nginx: [ OK ]

[root@test01 ~]# cat /usr/local/nginx/logs/nginx.pid //存储了nginx运行的进程号

15799

[root@test01 ~]# kill -HUP `cat /usr/local/nginx/logs/nginx.pid` //不间断服务重新启动nginx

[root@test01 init.d]# /etc/init.d/nginx stop

Stopping nginx: [ OK ]

[root@test01 init.d]# killall -9 nginx //结束nginx的全部经常

[root@test01 html]# pwd //安装nginx完成后，默认网站的路径

/usr/local/nginx/html

[root@test01 html]# ll //可以查看到默认网站为index.html，内容为以上测试内容。

二.安装php环境

nginx目前还不能直接支持php，必须先借助于fastcgi来驱动php。现在fastcgi较好的办法有2种，一个是spawn-fcgi，另外一个就是php-fpm，一般来说可能php-fpm更强大一点.

由于PHP5.3版本以后就自带php-fpm了，所以如果你用源码安装的话只需要enable fpm就可以了，下面来说说通过yum安装php-fpm

开始安装Nginx和PHP-FPM之前,你必须卸载系统中以前安装的Apache和PHP。用root登录输入下面的命令：

yum remove httpd* php*

增加额外资源库:

默认情况下，CentOS的官方资源是没有php-fpm的, 但我们可以从Remi的RPM资源中获得，它依赖于EPEL资源。我们可以这样增加两个资源库：

yum install yum-priorities –y

wget http://download.Fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

rpm -Uvh epel-release-6-8.noarch.rpm

rpm -Uvh remi-release-6.rpm

安装php,php-ftpm

yum --enablerepo=remi install php php-fpm

添加到系统自动运行

chkconfig --level 345 php-fpm on

PHP仅安装了核心模块，你很可能需要安装其他的模块，比如MySQL、 XML、 GD等等，你可以输入下列命令：

yum --enablerepo=remi install php-gd php-mysql php-mbstring php-xml php-mcrypt

第一次启动php-fpm，输入下列命令：

/etc/init.d/php-fpm start

三．配置PHP-FPM和Nginx

编辑Nginx的配置文件

vi /usr/local/nginx/conf/nginx.conf

修改如下：

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME/scripts$fastcgi_script_name;

include fastcgi_params;

}

配置fastcgi

vi /usr/local/nginx/conf/fastcgi_params

添加如下行：

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

添加php测试文件

vi /usr/local/nginx/html/index.php

添加以下内容：

<?php

phpinfo();

?>
