Redis Cluster Setup Password detailed

Precautions:

1. If you are building a cluster using the REDIS-TRIB.RB tool, do not configure the password before the cluster is built, and set the password by the config set + config rewrite command on a per machine basis.

2. If the password is set for the cluster, then both Requirepass and Masterauth need to be set, otherwise, when the master-slave switch occurs, it will encounter authorization problem, can simulate and observe the log

3. Each node must have the same password, or redirected will fail

1. config set masterauth  abc  

2. config set requirepass abc  

3. config rewrite  

After setting the password, redis-trib.rb check 192.168.0.107:6379

After setting the password, redis-trib.rb check 192.168.0.107:6379 the error connection is not on the instance, the workaround:

Vim/usr/lib/ruby/gems/1.8/gems/redis-3.3.0/lib/redis/client.rb

Class Redis
Class Client

DEFAULTS = {
: url = = Lambda {env["Redis_url"]},
: scheme = "Redis",
: host = "127.0.0.1",
:p ort = 6379,
:p ath = nil,
: Timeout = 5.0,
:p assword = "Gh*8pass",
:d B = 0,
:d river = nil,
: id = nil,
: tcp_keepalive = 0,
: reconnect_attempts = 1,
: Inherit_socket = False
}

Modify the default password to do it.
