配置文件:

php容器的镜像vphp:7.3-fpm是使用php官方的php:7.3-fpm镜像仅添加了一个nginx的用户和组制作的

目录结构

宿主机:
wordpress:/opt/html/wordpress html文件夹权限777

报错详情:

nginx:

2021/03/09 13:17:34 [error] 28#28: *3 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.0.117, server: localhost, request: "GET /wp-admin/install.php HTTP/1.1", upstream: "fastcgi://172.22.0.3:9000", host: "192.168.0.179:8080"

php-fpm:

172.22.0.4 -  09/Mar/2021:13:13:56 +0000 "GET /index.php" 404
172.22.0.4 -  09/Mar/2021:13:17:34 +0000 "GET /wp-admin/install.php" 404

访问http://宿主机IP:8080/wp-admin/install.php，网页报错File not found.
访问http://宿主机IP:8080/index.html，正常显示提前准备的html

基本上能百度/Google到的方法都试了,每次都是这个报错,但是访问html文件没问题

求助大牛！

Answer 1

docker-compose 里挂载卷的时候，nginx里

    - /opt/html/:/usr/share/nginx/html

php里

    - /opt/html/:/var/www/html

猜测是不是同一个目录挂载了两次，你可以把nginx的这一行去掉再试试

Answer 2

这一段里面的 目录是不是写错了？和 root指令不一致。

 location ~.php$ {
        root `/usr/share/nginx/html/`;
        fastcgi_pass php-fpm01:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
        include fastcgi_params;

Answer 3

先去 php-fpm01 容器中看目录是否映射到里面

Answer 4

问题已经解决了，两个点：
1.nginx里配置php的那一段配置

fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

要改为

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

2.php配置文件www.conf中

listen = 127.0.0.1:9000

改为

listen = 9000
