使用Nginx代替Openwrt中的uhttpd，并支持php

​ 在之前介绍过Openwrt部署typecho博客：Openert部署typecho博客，用的是默认的uhttpd，挺方便小巧；但是也有不足，就是性能很差，兼容性也不好，于是就萌生了使用Nginx代替uhttpd的想法。
于是需求就很明确了：

  1. 用Nginx实现Openwrt原本的uci界面
  2. 用Nginx实现Openwrt实现Typecho的php页面

现在Nginx已经集成在opkg源了，可以直接安装，安装之前先将uhttpd停用一下

1
/etc/init.d/uhttpd stop && /etc/init.d/uhttpd disable

也将之前uhttpd使用的php8-fastcgi停用一下

1
2
/etc/init.d/php8-fastcgi stop && /etc/init.d/php8-fastcgi disable
#并将/etc/config/php8-fastcgi里面的option enabled 1改成option enabled 0

停用完之后，安装Nginx涉及的包，如下：

uwsgi
uwsgi-syslog-plugin
uwsgi-cgi-plugin
uwsgi-luci-support
nginx-util
nginx-ssl-util
nginx-ssl
nginx
nginx-mod-luci
libopenssl-conf
openssl-util
nginx-mod-luci-ssl
luci-ssl-nginx
php8-fastcgi
php8-fpm

由于Nginx默认是不支持uci的，所以需要用uwsgi作为转发
装好之后，直接就可以访问Openwrt的uci界面了，接着就是折腾php这一块
1.先修改/etc/php8-fpm.d/www.conf，将chdir = / 改成 chdir = /www （注意/www是Typecho目录，这个看实际情况）
2.建立/etc/nginx/fastcgi_params文件，并放入以下内容

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;

3.新建/etc/nginx/conf.d/php.locations文件，并放入以下内容

此处解释一下，location ~ [^/].php(/|$)项是为了手动输入/www下多层目录的php文件，location = /blog/项是为了输入域名/blog后默认打开/blog下的index.php,location = /blog/admin项也是雷同
3.修改/etc/config/nginx文件，下面是我的配置，仅供参考

config main global
        option uci_enable 'true'

config server '_lan'
        #list listen '433 ssl default_server'
        #list listen '[::]:433 ssl default_server'
        option server_name '_lan'
        list include 'restrict_locally'
        list include 'conf.d/*.locations'
        option uci_manage_ssl 'self-signed'
        option ssl_certificate '/etc/nginx/conf.d/_lan.crt'
        option ssl_certificate_key '/etc/nginx/conf.d/_lan.key'
        option ssl_session_cache 'shared:SSL:32k'
        option ssl_session_timeout '64m'
        option access_log 'off; # logd openwrt'

config server '_redirect2ssl'
        list listen '80'
        list listen '[::]:80'
        option server_name '_redirect2ssl'
        option return '302 https://$host$request_uri'

config server '_redirect2ssl'
        list listen '90'
        list listen '[::]:90'
        option server_name '_redirect2ssl'
        option return '302 https://$host:433$request_uri'

解释：由于Openwrt的nginx启动脚本强制从/etc/config/nginx加载后转化成/var/lib/nginx/uci.conf，无法更改太多东西，所以/etc/config/nginx仅改一下端口、强制http转https，因为运营商默认屏蔽80\443端口，只能改其他端口
4.新建/etc/nginx/conf.d/new.conf,并放入以下内容：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
server { #see uci show 'nginx._lan'
    listen 433 ssl default_server;
    listen [::]:433 ssl default_server;
    server_name wangyougx_com;
    include restrict_locally;
    include conf.d/*.locations;
    ssl_certificate /etc/nginx/conf.d/wangyougx_com.crt;
    ssl_certificate_key /etc/nginx/conf.d/wangyougx_com.key;
    ssl_session_timeout 10m;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE; 
    ssl_prefer_server_ciphers on;
    include mime.types;
}

解释：如果你的域名已有证书，就填入，切记不要试图修改Nginx默认的_lan.crt！没用的；

操作到这里，基本算完成了，接下来重启以下服务：

1
2
3
/etc/init.d/uwsgi restart 
/etc/init.d/php8-fpm restart 
/etc/init.d/nginx restart

附加建议：
1.建议将/etc/uwsgi/emperor.ini 内的vassal-set项目改成vassal-set = die-on-idle=false(进程不休眠重启)
2.通过logread命令查看日志，会发现提示/www/favicon.ico文件不存在，这个是网页标签图标，可不理会，也可以找个喜欢的图标放进去即可。
