多个容器设置问题

支持 安装
1

大家好！在尝试配置多站点设置但彻底失败后，我最终采用了三个独立的容器：一个用于我当前的论坛，另外两个用于归档论坛。我选择了 socket 模式，成功让 NGINX 运行起来，并且 按照这些指南配置了 Let’s Encrypt。

我为归档论坛分配了一个 Unicorn 进程，当前论坛也只有一个，但我现在产生了一个疑问：我真的可以这样开箱即用吗？所有容器都在运行 Redis 和 Sidekiq，这是否会导致严重的冲突？或者我是否应该以某种方式将两个归档容器与第一个容器关联起来，以此类推？因为现在在执行恢复后，我收到了以下错误信息：

哎呀
驱动此讨论论坛的软件遇到了意外问题。对于造成的不便，我们深表歉意。

有关该错误的详细信息已被记录，并生成了自动通知。我们将对此进行检查。

无需进一步操作。不过，如果错误情况持续存在，您可以通过在网站的反馈类别中发布讨论主题来提供额外细节，包括重现错误的步骤。

我从 多站点主题 中了解到，进行多站点配置时应该有两个独立的容器，但我始终不太明白“数据容器”和“Web 容器”具体指什么。这是否意味着只有数据容器使用 SQL，而 Web 容器使用 Redis 和 Sidekiq，还是另有含义？

我学东西很快，对这方面也略知一二，但确实不能说我是一名系统管理员。

建议采用以下架构：一个容器运行 Redis 和 PostgreSQL，另一个容器运行 Web 服务器。如果您需要两个 Web 容器，则还需额外配置一个外部的 Nginx 反向代理来转发请求到这些 Web 容器。不过，部署单个多站点服务器会更加简便。

我在 /etc/nginx/sites-available/default 中有如下配置：

server {

        server_name www.uskojarukous.fi uskojarukous.fi nyforum.uskojarukous.fi;

        location /errorpages/ {
                alias /var/www/errorpages/;
        }

        location / {
                proxy_pass http://unix:/var/discourse/shared/nyforum/nginx.http.sock:;
                proxy_set_header Host $http_host;

其中至少有两个论坛运行正常……
