[Openwrt Project Development Note]:php+nginx installation (vii)

In the previous section, we have built the MySQL database, so in this section, I mainly explain the installation of PHP, as well as the PHP operating environment Nginx installation. Reference (http://www.right.com.cn/forum/thread-89216-1-1.html)

One, PHP installation

1. Install the PHP package.

OPKG Update
opkg Install php5 php5-mod-apc opkg install php5  opkg install php5  opkg install php5-mod- C6>PHP5

In the list above, I have installed a lot of PHP extension support, these packages can be added according to their own needs, not all of the PHP expansion pack needs to be installed.

Here, I cite a few more important extensions:

php5: This needless to say, PHP's main framework package, the software does not install, the following other packages are useless.

PHP5-MOD-APC: Alternative PHP cache (APC) is a valid open source Cache tool for PHP that caches opcode PHP intermediate codes. By installing APC, you can greatly speed up website access.

php5-mod-mysql / php-mod-pdo / php5-mod-pdo-mysql: These are necessary to use MySQL.

php5-mod-cgi/php5-mod-fastcgi: The key to web interaction.

php5-mod-xml: XML parsing

Php5-mod-json: JSON support

If you feel that you have enough space, you can install all PHP5-related packages once and for all (not recommended):

opkg updateopkg Install php5*

2. Configure PHP

After the installation of the PHP package, a php.ini file is generated in/etc, which is the PHP configuration file. We can make the necessary configuration according to our own needs. Modify PHP.ini:

Short_open_tag =on#如果php显示 ' not found ', the following line is commented #doc_root="/mnt/sda3/www" #在Dynamic The extension section, remove the annotations for the extensions we need to add ";"extension=ctype.soextension=curl.soextension=gd.soextension=mbstring.soextension=mcrypt.soextension=mysql.soextension=pdo.soextension=pdo_mysql.soextension=session.soextension=sockets.soextension=tokenizer.soextension=Xml.so[date]#修改时区date.timezone= asia/Chongqing[mysql]#修改MySQL的设置mysql.default_socket= /var/run/mysqld.sock

Tips: When you modify the time zone, you need to add zoneinfo, that is, the package zoneinfo-asia.opkg and zoneinfo-core.opkg mentioned earlier, if you do not add support, after the change will be an error.

I use the backfire inside is not with the above two packages.

Second, Nginx installation

1. Installing the Nginx Package

opkg updateopkg Install Nginx

2. Modify Nginx configuration file (/etc/nginx.conf)

Preparatory work:

(1) Create an nginx working directory:

Mkdir/mnt/sda3/www

(2) Add Nginx Users and user groups:

Opkg Install Shadow-useradd Shadow-groupadd

#添加用户组
Groupadd www
#添加用户到用户组www
Useradd-g www www
#将Nginx的工作目录绑定到www用户
Chown-r www:www/mnt/sda3/www

(3) Modify Nginx configuration file (/etc/nginx/nginx.conf):

The original Nginx configuration file is somewhat complex and splits it into different configuration files according to different functions:

User www www;#set user and user nameworker_processes1;#number of threads allowedPID/var/run/nginx.pid;#specify where the PID is storederror_log/var/Log/nginx_error.Log;#Specify the location of the Error.logEvents { UseEpoll; Worker_connections1024x768;#Specify the maximum number of connections}http {include MIME.types; Default_type Application/octet-stream; Access_log/var/Log/nginx/access.LogMain#Access.log Logsendfile on;    Tcp_nopush on; #keepalive_timeout 0;Keepalive_timeout $;    gzip on; Include Vhost. conf;#Server configuration file}

(4) Create the host configuration file under the/ect/nginx folder: vhost.conf

server {Listen       8000;#the original httpd monitoring Systemserver_name localhost; Root/mnt/sda3/www;#working directory of the website    Index  Index. htmlIndex. htmIndex. PHP Default.PHP; #Redirect Server error pages to the static page/50x.htmlError_page - 502 503 504/50x.html;#error page RedirectionLocation =/50x.HTML {root HTML; }    #Pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000Location ~\.php$ {#passing PHP scripts to FastcgiserverFastcgi_pass127.0.0.1:9000;#FastCGI's serverFastcgi_indexIndex.PHP; Fastcgi_param Script_filename/mnt/sda3/www/$fastcgi _script_name;#parameters of the fastcgiInclude Fastcgi_params;#fastcgi specific configuration files    }}

(5) fastcgi specific configuration:/etc/nginx/fastcgi_param

#resolves an issue with file type resolution errorsif($request _filename~* (.*)\.PHP) {Set$php _url$1;}if(!-E$php _url.PHP) {        return 403;} Fastcgi_param query_string$query _string; Fastcgi_param Request_method$request _method; Fastcgi_param Content_Type$content _type; Fastcgi_param content_length$content _length; Fastcgi_param Script_name$fastcgi _script_name;#the parameters in the following comment: The script name, and its settings need to be noted. Pro-Test effective #fastcgi_param script_filename$document _root/$fastcgi _script_name; Fastcgi_param Script_filename/mnt/sda3/www/$fastcgi _script_name; Fastcgi_param Request_uri$request _uri; Fastcgi_param Document_uri$document _uri; Fastcgi_param Document_root$document _root; Fastcgi_param Server_protocol$server _protocol; Fastcgi_param gateway_interface CGI/1.1; Fastcgi_param server_software nginx/$nginx _version; Fastcgi_param remote_addr$remote _addr; Fastcgi_param Remote_port$remote _port; Fastcgi_param server_addr$server _addr; Fastcgi_param Server_port$server _port; Fastcgi_param server_name$server _name;#PHP only, required if PHP is built with--enable-force-cgi-redirectFastcgi_param Redirect_status $;

(6) Open Nginx Service:

The opening of the Nginx service is a bit of a hassle. The first thing to do is open the FASTCGI service:

127.0. 0.1 9000 2 -f/usr/bin/php-cgi

If you want to boot up, place the above instruction under the/etc/rc.local script

If you have exit 0 in Rc.local, remember to comment it out, or you won't start listening on port 9000. This problem has been a long time ...

Open Nginx Service

/etc/init.d/nginx enable/etc/init.d/nginx start

Third, Nginx+php+mysql test

Under the/mnt/sda3/www folder, place the following files for testing:

When testing, remember to combine nginx log files:

/var/log/nginx/acesss. log/var/log/nginx/error. Log

1, index.html (test nginx service is normal open)

<!DOCTYPE HTML><HTMLLang= "en"><Head>    <MetaCharSet= "UTF-8">    <title>This is a test file</title></Head><Body>    <span>This is a HTML file</span></Body></HTML>

Show Results:

2. index.php (used to test whether the fastcgi is working properly)

<? php    phpinfo (); ?>

Show Results:

3.1.php (test file name is interpreted as normal)

<? PHP     Echo Date ("Y-m-d h:i:s",Time());? >

V. Problems encountered, and solutions

1. Question: When testing whether the fastcgi is working, the page displays "No input file specified".

Solution: Looking for a variety of solutions on the Web, I will write some of my useful articles and share them with you:

(1) Fastcgi_param script_filename/scripts$fastcgi_script_name; Switch

Fastcgi_param script_filename $document _root$fastcgi_script_name; #经测试无效.

Then change: Fastcgi_param script_filename /mnt/sda3/www/$fastcgi _script_name; #/mnt/sda3/www The working directory for the site

(2) fastcgi:9000 port does not open properly

Use the following command:

Netstat-ant |grep 9000

Port 9000 is not turned on. This means that the FASTCGI service is not turned on. Open manually:

127.0. 0.1 9000 2 -f/usr/bin/php-cgi

The pro-test is effective.

The Ok:nginx+php+mysql development environment was successfully ported to the OpenWrt platform.
