Docker + Nginx + PHP 訪問403，404問題

問題描述

搭建好docker nginx php后，瀏覽器訪問時，始終顯示404或403問題，卡了半天，因此記錄下解決方法和程序，希望能幫到讀者少踩坑，截圖如下：

曲折的排查

排查程序真的很曲折，剛開始以為是docker容器沒配置好，檔案映射沒映射好，各種折騰沒行，容器刪了又裝，裝了又刪，docker日志看了，也看不出問題，各種百度，方法各異都沒有解決問題，

問題原因

折騰到最后，目光轉移到 nginx.conf 上來了，果不其然就是，NGINX 的配置沒有配置好，

我這里主要是這三點導致的：

1. index.php 沒有配置
2. fastcgi_pass 沒有用容器名
3. fastcgi_param SCRIPT_FILENAME 路徑問題

解決方法

我這里php容器用的是官網的鏡像，實際中可能與我這邊不一樣，根據實際情況調整，這里只是提供一個思路，

貼上我修改后的組態檔：

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 $fastcgi_path_info;
       fastcgi_param  CI_ENV "local_dev";
       include        fastcgi_params;
       fastcgi_split_path_info ^(.+\.php)(.*)$;
       # 隱藏index.php需開啟
       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

最后貼上我的 docker-compose.yaml 檔案，希望能幫助到你，
