4. Monitoring page

5. Use the command line to allow flush

The installation program is convenient, but you will find that once the installation is complete, the flush option is not reconfigured on the management interface. If the flush option is not enabled during installation, however, what should I do if I want to enable it after the installation is complete?

Couchbase provides a powerful command line interface that supports couchbae-CLI to support command line management. This command is located in the \ couchbase \ Server \ bin folder in the couchbase installation directory.

To enable flush, we modify the configuration parameters of a bucket. We need to use the bucket-edit command and use -- bucket to specify the bucket for configuration modification. -- enable-flush = 1 indicates that the configuration is enabled, = 0: the display is disabled. The remaining parameters are the Administrator's account and password.

>couchbase-cli bucket-edit --bucket=default --enable-flush=1 -c 127.0.0.1  -u Administrator -p 123456

If it succeeds, the server returns a description

SUCCESS: bucket-edit

If the configuration is successful, you can call flush on the client. However, if the server is busy and cannot respond for a long time, an exception will be thrown, but it is not the 400 that has not enabled flush, but 503.

 

In addition, the generated configuration file is located in the D: \ couchbase \ Server \ var \ Lib \ couchbase \ config folder, and the file name is config. dat. This is a binary file and cannot be edited directly. It must be generated using a tool.

If you use the command line flush, you can use the bucket-flush command. Use -- bucket to specify the target.

D:\Couchbase\Server\bin>couchbase-cli bucket-flush --bucket=default -c 127.0.0.1:8091 --force -u Administrator -p 123456

The returned result is as follows.

Database data will be purged from disk ...SUCCESS: bucket-flush

 

6. the. NET client refreshes the cache.

The original flushall method has expired and needs to be managed using the couchbaecluster class in the couchbase. Management namespace.

Couchbase.Management.CouchbaseCluster cluster    = new Couchbase.Management.CouchbaseCluster("couchbase");cluster.FlushBucket("default");

 

 

Good luck!
