基于路由器的博客：（二）搭建nginx+php+mysql环境

上一步已经把HG255D的系统刷为OpenWrt，将环境搭建起来就可以上传博客的安装包了
先上一个php探针

1.安装软件（我的固件已经将nginx、php编译进去了，这一步只需安装mysql、spawn和shadow相关的软件）

opkg update

opkg install block-mount #自动挂载U盘
opkg install mysql-server 
opkg install spawn-fcgi zoneinfo-core zoneinfo-asia
opkg install shadow-groupadd shadow-useradd

2.创建账户、数据库文件夹等

groupadd www
useradd -g www www
mkdir /mnt/sda1/web #确保挂载了U盘
chown -R www:www /mnt/sda1/web
mkdir -p /mnt/sda1/data /mnt/sda1/data/mysql /mnt/sda1/data/tmp
3.修改/etc/my.cnf
datadir                = /mnt/sda1/data/mysql/
tmpdir                = /mnt/sda1/data/tmp/

4.启动mysql

/etc/init.d/mysqld start

5.输入如下命令创建mysql的密码（记住账户密码）

/usr/bin/mysqladmin -u root password 123456

6.登陆数据库

mysql -u root -p

7.连接上mysql,创建数据库（aaaa随意写，记住即可，安装博客时需要填）

create database aaaa
\g

8.退出mysql

quit

9.修改/etc/nginx/nginx.conf

user www www;
worker_processes  1;
pid        /var/run/nginx.pid;
error_log  /var/log/nginx_error.log;
events {
        use epoll;
        worker_connections  1024;
}

http {
        include mime.types;
        default_type application/octet-stream;
        sendfile on;
        tcp_nopush on;
        #keepalive_timeout 0;
        keepalive_timeout 65;
        gzip on;
        access_log   off;
    
        include       vhost.conf;
}

10.修改/etc/nginx/fastcgi_params，解决Nginx文件类型错误解析漏洞

if ($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;
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 was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

11.添加/etc/nginx/vhost.conf（端口需要修改成80以外的端口，我这里设置成82）

server {
        listen       82;
        server_name  localhost;
        root  /mnt/sda1/web;
        index  index.html index.htm index.php default.php;
        error_page   500 502 503 504  /50x.html;

        location = /50x.html {
        root html;
        }

        location ~* ^.+\.php(\/.*)*$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

12.修改/etc/php.ini

short_open_tag = on
#doc_root = "/mnt/www" 

extension=ctype.so
extension=curl.so
extension=gd.so
extension=mbstring.so
extension=mcrypt.so
extension=mysql.so
extension=pdo.so
extension=pdo_mysql.so
extension=session.so
extension=sockets.so
extension=tokenizer.so
extension=xml.so

[Date]
date.timezone = Asia/Shanghai

[MySQL]
mysql.default_socket = /var/run/mysqld.sock

13.启动spawn-fcgi（如需开机自动运行，可将命令添加到/etc/rc.local）

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 2 -f /usr/bin/php-cgi

14.启动nginx

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

接着就可以上传类似emlog、TypeCho等博客安装程序了
