安裝設置 {: #setup }

Docker ??

  • wordpress - Docker Hub #ril

    $ docker run --name some-wordpress --link some-mysql:mysql -d wordpress

    If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:

    $ docker run --name some-wordpress --link some-mysql:mysql -p 8080:80 -d wordpress

    Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.

    • The following environment variables are also honored for configuring your WordPress instance:

      • -e WORDPRESS_DB_HOST=... (defaults to the IP and port of the linked mysql container)

      • -e WORDPRESS_DB_USER=... (defaults to "root")

      • -e WORDPRESS_DB_PASSWORD=... (defaults to the value of the MYSQL_ROOT_PASSWORD environment variable from the linked mysql container)

        這是 container link 特有的效果 -- recipient container (WordPress) 會收到 source container (MySQL) 的環境變數。

      • -e WORDPRESS_DB_NAME=... (defaults to "wordpress")

      • -e WORDPRESS_TABLE_PREFIX=... (defaults to "", only set this when you need to override the default table prefix in wp-config.php)

      • -e WORDPRESS_AUTH_KEY=..., -e WORDPRESS_SECURE_AUTH_KEY=..., -e WORDPRESS_LOGGED_IN_KEY=..., -e WORDPRESS_NONCE_KEY=..., -e WORDPRESS_AUTH_SALT=..., -e WORDPRESS_SECURE_AUTH_SALT=..., -e WORDPRESS_LOGGED_IN_SALT=..., -e WORDPRESS_NONCE_SALT=... (default to unique random SHA1s) 這是做什麼的??

      • -e WORDPRESS_DEBUG=1 (defaults to disabled, non-empty value will enable WP_DEBUG in wp-config.php)

      • -e WORDPRESS_CONFIG_EXTRA=... (defaults to nothing, non-empty value will be embedded verbatim inside wp-config.php -- especially useful for applying extra configuration values this image does not provide by default such as WP_ALLOW_MULTISITE; see docker-library/wordpress#142 for more details)

    • If the WORDPRESS_DB_NAME specified does not already exist on the given MySQL server, it will be created automatically upon startup of the wordpress container, provided that the WORDPRESS_DB_USER specified has the necessary permissions to create it.

    • If you'd like to use an external database instead of a linked mysql container, specify the hostname and port with WORDPRESS_DB_HOST along with the password in WORDPRESS_DB_PASSWORD and the username in WORDPRESS_DB_USER (if it is something other than root):

      $ docker run --name some-wordpress -e WORDPRESS_DB_HOST=10.1.2.3:3306 \
    -e WORDPRESS_DB_USER=... -e WORDPRESS_DB_PASSWORD=... -d wordpress

    • When running WordPress with TLS behind a reverse proxy such as NGINX which is responsible for doing TLS termination, be sure to set X-Forwarded-Proto appropriately (see "Using a Reverse Proxy" in "Administration Over SSL" in upstream's documentation). No additional environment variables or configuration should be necessary (this image automatically adds the noted HTTP_X_FORWARDED_PROTO code to wp-config.php if any of the above-noted environment variables are specified).

      就 client --> https:// --> reverse proxy --> http:// --> WordPress 的關係及 X-Forwarded-Proto - HTTP | MDN 看來，reverse proxy 要在 X-Forwarded-Proto 記錄 client --> revere proxy 這一段真正的 protocol，因為 reverse proxy --> WordPress 這一段固定走 HTTP，若想知道 client 走的 protocol，就必須要取用 X-Forwarded-Proto header -- 猜想是用來產生 URL。
