[Docs: Install from Package Guide] have to modify webserver redis local configuration

[studioego]

Main idea

In the Installation Guides > Install from Packages > Install Backend.AI Webserver > Local configuration, I found wrong redis configurations.

The redis configurations in the halfstack.conf of "main" repo and the webserver.conf in the Install from Package Guide example are different.

Redis configurations in the halfstack.conf of the main repo

[session]

[session.redis]
addr = "localhost:8111"
# password = "mysecret"
# service_name = "mymaster"
# sentinel = "127.0.0.1:9503,127.0.0.1:9504,127.0.0.1:9505"

[session.redis.redis_helper_config]
# socket_timeout = 5
# socket_connect_timeout = 2
# reconnect_poll_timeout = 0.3

max_age = 604800  # 1 week
flush_on_startup = false
login_block_time = 1200  # 20 min (in sec)
login_allowed_fail_count = 10
max_count_for_preopen_ports = 10

Redis configurations in the webserver.conf of the Install from Package Guide

[session]
redis.host = "bai-m1"
redis.port = 8110
redis.db = 5
redis.password = "develove"
max_age = 604800  # 1 week
flush_on_startup = false
login_block_time = 1200  # 20 min (in sec)
login_allowed_fail_count = 10
max_count_for_preopen_ports = 10

If you run the following Redis configurations in the webserver.conf of Install from Package Guide, you get some error messages.

(.venv) bai@dhsung:~/webserver$ python -m ai.backend.web.server -f ${HOME}/.config/backend.ai/webserver.conf

During handling of the above exception, another exception occurred:

As a result, you have to apply the redis configuration of the halfstack.conf of the main repo to run the webserver.
