我已经在 WordPress 中设置了带有缓存的 nginx。
我正在使用https://wordpress.org/plugins/nginx-helper/，但是登录页面似乎被缓存了，而它不应该被缓存（因此显示登录栏）。
一些未登录（也没有任何 cookies/浏览器缓存）的访问者会看到登录栏（如果他们点击栏内的任何内容，它会将他们重定向到登录页面）。
此外，当我单击 WordPress 中的清除缓存按钮时，页面仍然显示为XCache HIT...真正清除的唯一方法是通过rm -rf /dev/shm/nginx。
我确实安装了以下模块：

该配置看起来非常熟悉 - 我将其大部分内容发布在另一个帖子中：）可惜它缺少一个重要部分。
location = /wp-login.php {
fastcgi_keep_conn on;
fastcgi_intercept_errors on;
fastcgi_pass php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
# No caching
more_clear_headers "Cache-Control";
add_header Cache-Control "private, max-age=0, no-cache, no-store";
more_clear_headers "Expires";
}
此外，Nginx Helper 无法清除缓存。我花了很长时间尝试让它工作，但就是不行。我无法获得Nginx 缓存插件也可以工作。
Nginx 缓存更新
来自评论中的@rafa：问题是 nginx-helper 的缓存文件路径硬编码为 /var/run/nginx-cache，而 OP 的配置指示缓存文件的路径为 /dev/shm/nginx。我只需将 fastcgi_cache_path 更改为“正确”路径，nginx-cache 就可以正常工作
