-    Although the configurations in environment have higher priority than the configurations in config files, we recommend that you remove or modify the cache configuration in the following files to avoid ambiguity:：
+        ### Redis
+        REDIS_HOST=redis
+        REDIS_PORT=6379
+        REDIS_PASSWORD=
 
-    - `seafile.conf`: remove the `[memcached]` section
+        ### Memcached
+        MEMCACHED_HOST=memcached
+        MEMCACHED_PORT=11211
+        ```
 
-    - `seahub_settings.py`: remove the key `default` in variable `CACHES`
+    !!! tip "Optional but recommended modifications for further configuration files"
