Specific steps for installation and configuration of nginx+php+mysql based on ubuntu_PHP tutorial

1、更新

1	sudo apt-get update

2、安装nginx

1	sudo apt-get intsall nginx

Ubuntu安装之后的文件结构大致为:
* 所有的配置文件都在/etc/nginx下,并且每个虚拟主机已经安排在了/etc/nginx/sites-available下
*程序文件在/usr/sbin/nginx * 日志放在了/var/log/nginx中
*并已经在/etc/init.d/下创建了启动脚本nginx
* 默认的虚拟主机的目录设置在了/var/www/nginx-default

下面可以启动nginx来看看效果(请确保80端口没有其他服务在使用):

1	sudo /etc/init.d/nginx start

#或者简单的

1	service nginx start

然后打开浏览器,查看http://localhost/ 看看是否看到了”Welcome to nginx!” 如果看到了,说明安装成功.
当然,基本上,这块儿都不会出问题. 如果运行不成功,可以先

1	sudo killall apache2

杀掉apache进程
3、安装php

sudo apt-get install php5 php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-pspell php5-recode php5-snmp php5-tidy php5-xmlrpc php5-sqlite php5-xsl

 

4、安装spawn-fcgi
为什么要安装spawn-fcgi呢,它用来控制php-cgi进程,以防止进程崩溃或是单进程的效率太低.
网上很多人都说要使用spawn-fcgi必须得安装lighttpd,实际上不必要,可以直接安装spawn-fcgi
运行:

1	sudo apt-get install spawn-fcgi

5、配置
接下来就是最让人头疼的配置.
配置Nginx和spawn-fcgi配合运行
(1).在/etc/nginx/fastcgi_params 文件最后,加入一行,可以用

1	sudo vi /etc/nginx/fastcgi_params

加入此行:

1	fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

(2).另外需要在PHP-CGI的配置文件(Ubuntu 上此配置文件位于/etc/php5/cgi/php.ini)中,找到cgi.fix_pathinfo选项,修改为:

1	cgi.fix_pathinfo=1;

这样php-cgi方能正常使用SCRIPT_FILENAME这个变量.
(3).打开/etc/nginx/sites-available/default文件在

1 2 3

server { listen 80; server_name localhost;

下面添加web根目录的绝对地址,这里是使用的是nginx的默认地址

1	root /var/www/nginx-default

即root和server_name同级这段即相当于apache的默认目录
如果没有这个的话,容易在执行php 文件的时候,会提示”No input file specified”.
我就曾在此绕了好大个圈子才发现问题.然后修改

1 2 3 4 5 6

#location ~ .php$ { #fastcgi_pass 127.0.0.1:9000; #fastcgi_index index.php; #fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; #includefastcgi_params; #}

修改成

1 2 3 4

location ~ .php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;

include /etc/nginx/fastcgi_params; #包含fastcgi的参数文件地址
6、开始fast_cgi进程

1、sudo /usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

7、设置开机启动fastcgi进程并启动

1	sudo vi /etc/rc.local

添加下一行

1	/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

如果打开php文件出现:No input file specified请检查php.ini的配置中

1	cgi.fix_pathinfo=1

1

doc_root=

还有,每个虚机要根据自己不同的虚机设置不同的目录,要保证这个路径正确.
检查/etc/nginx/sites-available下的配置文件中,server内包含 root 及地址 而非location内的root
启动

1	fast-cgisudo /usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

The meaning of the parameters is as follows
* -f Specify the execution program location of the process that calls FastCGI,according to Specific settings for PHP installed on the system
* -a is bound to the address addr
* -p bind to portport
* -s bind to path of unix socketpath
* -C Specifies the number of processes generated by FastCGI, Defaults to 5 ( only for PHP)
* -PSpecifies the of the spawned process PIDFile path
* -u and -g FastCGIWhat identity to use(-u User -g User Group)Run, Ubuntu You can use www-data, and other configurations according to the situation , such as nobody, apache, etc. Now you can put a probe in the root directory of web or phpTested the file
8, installedmysql

1	sudo apt-get install mysql-server mysql-client

1

sudo apt-get install mysql-server mysql-client

You will be prompted to enter the Rootuser password ,
in order to start .

1	sudo /etc/init.d/mysql start

MySQL

1	sudo /etc/init.d/mysql start

Test

1	mysql -uroot -p

mysql

whether the service is normal

:Run

1

1	show databases;

mysql -uroot -p

Entermysqlpassword

1	show databases;
