debian 下安装切换apache到nginx,php5

1: 前言 以前debian作开发机server是apache，工作需要切换到nginx，有时候两个都要使用。作个简单的笔记。注意，本文仅仅是在debian 7（wheezy） 上。其它OS有其它OS的配置和安装，不能保证一致性。apache的安装配置就参考前面发的文章了。 2: 安装 nginx ph

 以前debian作开发机server是apache，工作需要切换到nginx，有时候两个都要使用。作个简单的笔记。注意，本文仅仅是在debian 7（wheezy） 上。其它OS有其它OS的配置和安装，不能保证一致性。apache的安装配置就参考前面发的文章了。

2:安装 nginx  php5-cgi php5-fpm spawn-fcgi 

#apt-get install nginx nginx-full nginx-common php5-cgi php5-fpm spawn-fcgi

3:配置各个的php.ini 

可以#cd /etc/php5 里面看见，

有

/etc/php5/apache2/php.ini   

/etc/php5/cgi/php.ini 

/etc/php5/cli/php.ini 

/etc/php5/fpm/php.ini 分别对应不同的php.ini 配置

#vim /etc/php5/cgi/php.ini  去掉cgi.fix-pathinfo=1 的注释

4:配置nginx.conf

在/etc/nginx/nginx.conf

把下面的复制进去, 或者你可以对比下修改

user www-data;
worker_processes 12;
pid /var/run/nginx.pid;

worker_rlimit_nofile 51200;

#	}
# 
#	server {
#		listen     localhost:143;
#		protocol   imap;
#		proxy      on;
#	}
#}

5: 配置default

在/etc/nginx/sites-available/default, 注意，下面我的配置文件写了两个 注释掉了  php5-cgi  的， 打开了php5-fpm的。 我这里用的是php5-fpm

如果你需要用spawn-fcgi，就需要php5-cgi 加########的那段。/home/www 是我的www目录。你可以对着改成你的www目录。root  /home/www 这里也是。 我打开了自动索引，autoindex这个。

# You may add here your
# server {
#	...
# }
# statements for each of your virtual hosts to this file

##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

6:启动

启动模式有几种，可以是spawn-fcgi 或者是php5-fpm  或者还是apache 

如果是自启动php-fpm ,

可以通过sysv-rc-conf 工具查看是否在开机启动里面 (#apt-get install sysv-rc-conf),  默认是在的

关掉spawn-fcgi 或者php5-fpm

spawn-fcgi

#netstat -anp | grep 9000

#killall -HUP php5-cgi

php5-fpm

#/etc/init.d/php5-fpm stop

如果想要spawn-fcgi 支持/etc/init.d/

开机自启动spawn-fcgi 模式

#vim /etc/rc.local 增加

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid -C 4

参数根据你机器性能来，我这里是测试机。

创建系统启动停止命令

#cd /etc/init.d/

#touch fastcgi

把下面的文件保存到刚才创建的fastcgi, 就可以支持 /etc/init.d/fastcgi start|stop|reload 等操作了

#!/bin/bash
# DESC: NGINX php5 FastCGI(spawn-fcgi) init shell script

PROVIDES=php5-cgi
LIGHTTPD_FCGI=/usr/bin/spawn-fcgi
SERVER_IP=127.0.0.1
SERVER_PORT=9000
SERVER_USER=www-data
SERVER_GROUP=www-data
PHP_CGI=/usr/bin/php5-cgi
KILLALL=/usr/bin/killall

. /lib/lsb/init-functions

cmd=$1

pcgi_start(){
	echo "Starting $PROVIDES..."
	$LIGHTTPD_FCGI -a $SERVER_IP -p $SERVER_PORT -u $SERVER_USER -g $SERVER_GROUP -f $PHP_CGI -C 15 -P /var/run/fastcgi-php.pid
	echo "Done."
}

pcgi_stop(){
	echo "Killing $PROVIDES..."
	$KILLALL $PROVIDES
	echo "Done."
}

pcgi_restart(){
	pcgi_stop
	pcgi_start
}

pcgi_status(){
	status_of_proc -p /var/run/fastcgi-php.pid "/usr/bin/php5-cgi" php5-cgi && exit 0 || exit $?
}

pcgi_help(){
	echo "Usage: $0 {start|stop|restart|status}"
}

case ${cmd} in
	[Ss][Tt][Aa][Rr][Tt]) pcgi_start;;
	[Ss][Tt][Oo][Pp]) pcgi_stop;;
	[Rr][Ee][Ss][Tt][Aa][Rr][Tt]) pcgi_restart;;
	[Ss][Tt][Aa][Tt][Uu][Ss]) pcgi_status ;;
	*)      pcgi_help ;;
esac

如果要停止php5-fpm切换到spawn-fcgi

#/etc/init.d/php5-fpm stop

编辑/etc/nginx/sites-available/default 把php5-fpm

#fastcgi_pass unix:/var/run/php5-fpm.sock;  

注释掉，打开php5-fcgi 那个

fastcgi_pass 127.0.0.1:9000;

保存

重启nginx 配置

#/etc/init.d/nginx reload

查看phpinfo

如果要停止掉php5-fpm 类似，如果要关掉nginx启用apache更简单了

#/etc/init.d/nginx stop

#/etc/init.d/apache2 restart

7: 如果需要配置多个不同的项目，可以在/etc/nginx/nginx.conf 里面的 

include /etc/nginx/sites-enabled/*; 这里改成其他的子配置文件，到时根据需求方便切换。然后/etc/init.d/nginx reload 就可以了

8: 如果想要apache和nginx都同时可以工作, 这里我们让nginx走80端口, apache走8080, 修改/etc/apache/ports.conf文件, 改80为8080, 同理还要修改/etc/apache/site-available/里面的虚拟主机的端口为8080

NameVirtualHost *:8080
Listen 8080

重启apache即可通过xxx.xxx.xxx.xxx:8080来访问了

9: 如果nginx 和php5-fpm 搭配的时候访问php页面报502, 检查/etc/php5/fpm/pool.d/www.conf 里面的配置,

比如, 因为我的www目录授权是给的tom, 所以这里要修改. 保存后重启fpm和nginx即可.

listen.owner = tom
listen.group = tom

listen = /var/run/php5-fpm.sock;

listen.allowed_clients = 127.0.0.1

10: 如果要关掉nginx和php的版本号显示, 防止别人来嗅探对应的版本的漏洞.

nginx在http那段, 把 server_tokens off; 开启 

并且把对应的/etc/nginx/fastcgi_params  删除掉$nginx_version

        fastcgi_param SERVER_SOFTWARE nginx;

然后去关掉所有的php的版本, 找到php.ini(cgi的,fpm的,cli的,apache的 一共有四份不同的php.ini对应不同的)

把下面的on关闭为off 重启对应的fpm/cgi/apache 和nginx服务器就可以了.

expose_php = Off

curl --head http://127.0.0.1/info.php 

会看不到nginx和php的版本信息了.
