无法在 docker 中启动 sphinxsearch

Question

我正在尝试 docker 化 Rails 应用程序。它使用 Sphinx 进行搜索，我无法通过 docker.运行。

这是我运行 docker-compose up 并尝试执行搜索时发生的情况：

web_1     | [1fd79fbf-2e77-4af5-90ad-ae3637ada807]   Sphinx Query (1.9ms)  SELECT * FROM `field_core` WHERE MATCH('soccer') AND `sphinx_deleted` = 0 ORDER BY `name` ASC LIMIT 0, 10000
web_1     | [1fd79fbf-2e77-4af5-90ad-ae3637ada807] Completed 500 Internal Server Error in 27ms (ActiveRecord: 3.0ms)
web_1     | [1fd79fbf-2e77-4af5-90ad-ae3637ada807] 
web_1     | ThinkingSphinx::ConnectionError (Error connecting to Sphinx via the MySQL protocol. Can't connect to MySQL server on '127.0.0.1' (111)):
web_1     |   app/controllers/fields_controller.rb:7:in `search'

这是 docker-compose run sphinx rake ts:index 的结果：

sh: 1: searchd: not found

The Sphinx start command failed:
  Command: searchd --pidfile --config "/app/config/development.sphinx.conf"
  Status:  127
  Output:  See above

There may be more information about the failure in /app/log/development.searchd.log.

docker-compose.yml:

version: '3'
services:
  db:
    image: circleci/mysql:5.7
    restart: always
    volumes:
      - mysql_data:/var/lib/mysql
    ports:
      - "3309:3309"
    expose:
      - '3309'

    command: rails server -p 3000 -b '0.0.0.0'
    ports:

    expose:
      - '3000'
    depends_on:
      - db

Docker 文件：

FROM ruby:2.4.1

RUN apt-get update && apt-get install -qq -y build-essential nodejs --fix-missing --no-install-recommends

RUN curl -s \
    http://sphinxsearch.com/files/sphinxsearch_2.3.2-beta-1~wheezy_amd64.deb \
    -o /tmp/sphinxsearch.deb \

WORKDIR /app

COPY Gemfile Gemfile.lock ./

RUN gem install bundler && bundle install --jobs 20 --retry 5

COPY . ./

EXPOSE 3000

CMD ["bundle", "exec", "rails", "server", "-b", "0.0.0.0"]

thinking_sphinx.yml:

development: &common
  min_infix_len: 1
  charset_table: "0..9, english, U+0021..U+002F"
  port: 9306
  address: sociaball_mysql_1
production:
  <<: *common

因此，rake 在 sphinx 容器中不可用，sphinx 脚本在应用程序的容器中不可用。我做错了什么？

Answer 1

当运行 rake 任务时，Thinking Sphinx 需要 Rails 应用程序的副本，因此您需要在 Sphinx 容器中拥有应用程序的副本。这将确保（一旦您捆绑了 gems）rake 存在于 Sphinx 容器中，其中也存在 Sphinx 二进制文件。

Answer 2

所以。

而不是运行 rake 任务，我只是直接在 sphinx 容器中执行它的操作。像这样：

docker-compose run --rm sphinx indexer \
--config "/etc/sphinxsearch/sphinxy.conf" --all --rotate

关于 500 错误。这是由 thinking_sphinx.yml 中的错误配置引起的。它应该指向带有 sphinx 而不是 db:

的远程主机

development: &common
  # ...
  address: sociaball_sphinx_1
