Re: Websocket 200 error
The redis issue solved, by revising redis configuration: config set
stop-writes-on-bgsave-error no
And the redis server can be restarted.

Re: Websocket 200 error
I am guessing maybe there is an issue with the redis-server? *The log I
received from Daphne*:
2019-02-18 21:07:54,543 ERRORError trying to receive messages: Error
running script (call to f_3640886a0c8901ca9188f5f7a5f7a346145b9c5f):
@user_script:3: @user_script: 3: -MISCONF Redis is configured to save RDB
snapshots, but is currently not able to persist on disk. Commands that may
modify the data set are disabled. Please check Redis logs for details about
the error.
So I check *redis log*:
[1418] 18 Feb 16:09:27.071 * 1 changes in 900 seconds. Saving...
[1418] 18 Feb 16:09:27.072 * Background saving started by pid 2834
[2834] 18 Feb 16:09:27.073 # Failed opening .rdb for saving: Permission
denied
[1418] 18 Feb 16:09:27.172 # Background saving error
I searched ways to solve the problem and set the permission of .rdb to 777.
But still has this error in redis log.
I also find I cannot shutdown and restart redis.
When I type redis-server in the command line, the log info:
[2892] 18 Feb 16:14:32.457 # Warning: no config file specified, using the
default config. In order to specify a config file use redis-server
/path/to/redis.conf
[2892] 18 Feb 16:14:32.459 # Unable to set the max number of files limit to
10032 (Operation not permitted), setting the max clients configuration to
3984.

bind: Address already in use
