Docker + Nginx + PHP 访问403，404问题

Posted 2021-09-01 狂野小青年

问题描述

搭建好docker nginx php后，浏览器访问时，始终显示404或403问题，卡了半天，因此记录下解决方法和过程，希望能帮到读者少踩坑，截图如下：

曲折的排查

排查过程真的很曲折，刚开始以为是docker容器没配置好，文件映射没映射好，各种折腾没行。容器删了又装，装了又删，docker日志看了，也看不出问题，各种百度，方法各异都没有解决问题。

问题原因

折腾到最后，目光转移到 nginx.conf 上来了，果不其然就是，NGINX 的配置没有配置好。

 我这里主要是这三点导致的：

1. index.php 没有配置
2. fastcgi_pass 没有用容器名
3. fastcgi_param  SCRIPT_FILENAME 路径问题

解决方法

我这里php容器用的是官网的镜像，实际中可能与我这边不一样，根据实际情况调整，这里只是提供一个思路。

 贴上我修改后的配置文件：

server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    root /usr/share/nginx/html;

    location / {
        index  index.html index.htm index.php;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \\.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \\.php$ {
       fastcgi_pass   php:9000;
       fastcgi_index  index.php;
       #fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
       #fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
       fastcgi_param  SCRIPT_FILENAME /www/$fastcgi_script_name;
       fastcgi_param  SCRIPT_NAME $fastcgi_script_name;
       fastcgi_param  PATH_INFO $fastcgi_path_info;
       fastcgi_param  CI_ENV "local_dev";
       include        fastcgi_params;
       fastcgi_split_path_info ^(.+\\.php)(.*)$;
       # 隐藏index.php需开启
       fastcgi_param  PATH_TRANSLATED     $document_root$fastcgi_path_info;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\\.ht {
    #    deny  all;
    #}
}

 最后

最后贴上我的 docker-compose.yaml 文件，希望能帮助到你。
