多个PHP-FPM虚拟主机的最小Docker Nginx配置

Question

我需要升级一些仍然运行PHP5.6的非常旧的PHP站点，因为我有其他运行PHP7和PHP8的站点，我想我应该利用Docker来实现这一点。

我使用的是hub的默认Docker PHP-FPM和Nginx图像。码头工人。通用域名格式。

我在Ubuntu20下的Docker for Windows和WSL2上运行这个。如果您也在Windows 10上，下面是我能找到的关于使用Docker for PHP开发设置WSL2以完美工作的最佳指南。

Dockerfile文件

FROM nginx

COPY nginx.conf /etc/nginx/nginx.conf
COPY site1.conf /etc/nginx/conf.d/site1.conf
COPY site2.conf /etc/nginx/conf.d/site2.conf

nginx.conf

这是 /etc/nginx/nginx.confnginx官方图像中的默认值，除了两行。

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    # added this once some other SO posts suggested it for multiple server_name directives
    server_names_hash_bucket_size 64;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

    # had to add this, the default nginx.conf in the docker image doesn't include sites-enabled
    include /etc/nginx/sites-enabled/*.conf;
}

server {
    listen         80 default_server;
    listen         [::]:80 default_server;
    server_name    example1.com www.example1.com;
    root           /var/www/example1.com;
    index          index.html;

    location / {
        try_files $uri $uri/ =404;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

}

地点2。形态

server {
    listen         80;
    listen         [::]:80;
    server_name    example2.com www.example2.com;
    root           /var/www/example2.com;
    index          index.html;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

目录结构

/home/me/nginx-test/Dockerfile
/home/me/nginx-test/site1/index.html
/home/me/nginx-test/site1/test.php
/home/me/nginx-test/site2/index.html
/home/me/nginx-test/site2/test.php

把<代码>

/etc/hosts

127.0.0.1  example1.com
127.0.0.1  example2.com

这是我的方法来站起来测试一切。

$ cd ~/nginx-test
$ docker pull nginx
$ docker pull php:5.6.40-fpm
$ docker build -t web:test .
$ docker run --name php -v /home/me/nginx-test/site1:/var/www/example1 -v /home/me/nginx-test/site2:/var/www/example2 -d php:5.6.40-fpm
$ docker run --name test -p 80:80 -v /home/me/nginx-test/site1:/var/www/example1 -v /home/me/nginx-test/site2:/var/www/example2 --link php:php -d web:test

请注意，您必须首先启动php容器，并将其命名为php，以便当您启动Web容器并将其链接到php容器时，它可以找到它。这也是需要的fastcgi_passphp： 9000指令在两个nginx配置文件。

docker ps-a

$ docker ps -a
CONTAINER ID   IMAGE            COMMAND                  CREATED          STATUS         PORTS                NAMES
37edb342d7b2   web:test         "/docker-entrypoint.…"   5 seconds ago    Up 4 seconds   0.0.0.0:80->80/tcp   test

现在，当我浏览到http://example1.com和http://example2.com我将列出相应的索引。html页面。

现在为了使grep日志更容易一点，让我们将$server_name添加到nginx.conflog_format。有关nginx变量的官方列表的更多详细信息。

nginx。形态编辑，第16行

    log_format  main  '$remote_addr - $remote_user [$time_local] "$server_name $request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

拆毁重建

$ docker stop test && docker rm test && docker stop php && docker rm php
$ docker build -t web:test .
$ docker run --name php -v /home/me/nginx-test/site1:/var/www/example1 -v /home/me/nginx-test/site2:/var/www/example2 -d php:5.6.40-fpm

下面是一些更详细的诊断信息。

卷增加了吗？

$ docker exec -it test bash
root@37edb342d7b2:/# cd /var/www/example1
root@37edb342d7b2:/var/www/example1# ls
index.html  test.php

是的。

在两个容器里？

$ docker exec -it php bash
root@45ac2fb3d1d4:/var/www/html# ls -la /var/www/example2
