Redis Configuration Password Authentication

Redis Configuration Password

1. Configuring with configuration Files
The Yum-style installation of Redis profiles is typically in/etc/redis.conf, which opens the configuration file to find

?

1	#requirepass foobared

Remove the comment before the line, and change the password to the desired password, save the file

?

1	requirepass myRedis

Restart Redis

?

1234	sudo service redis restart#或者sudo service redis stopsudo redis-server /etc/redis.conf

This is the time to try to log in to Redis and find that it is possible to mount, but the specific command is prompt operation is not allowed

?

redis-cli -h 127.0.0.1 -p 6379redis 127.0.0.1:6379>redis 127.0.0.1:6379> keys *(error) ERR operation notpermittedredis 127.0.0.1:6379> select 1(error) ERR operation notpermittedredis 127.0.0.1:6379[1]>

Try to log in with a password and execute a specific command to see that it can be executed successfully

redis-cli -h 127.0.0.1 -p 6379 -a myRedisredis 127.0.0.1:6379> keys *1) "myset"2) "mysortset"redis 127.0.0.1:6379> select1OKredis 127.0.0.1:6379[1]> config get requirepass1) "requirepass"2) "myRedis"

2. Configure through the command line

?

redis 127.0.0.1:6379[1]> config setrequirepass my_redisOKredis 127.0.0.1:6379[1]> config get requirepass1) "requirepass"2) "my_redis"

No need to restart Redis
Using the old password configured in the configuration file in the first step to sign in to Redis, you will find that the original password is not available and the operation is rejected

?

123	redis-cli -h 127.0.0.1 -p 6379 -a myRedisredis 127.0.0.1:6379> config get requirepass(error) ERR operation notpermitted

Log in to Redis with the modified password to perform the appropriate action

?

1234	redis-cli -h 127.0.0.1 -p 6379 -a my_redisredis 127.0.0.1:6379> config get requirepass1) "requirepass"2) "my_redis

Try to restart Redis, log in to Redis with the newly configured password, discover that the new password is invalid, and Redis re-uses the password in the configuration file

?

sudo service redis restartStopping redis-server:                                     [  OK  ]Starting redis-server:                                     [  OK  ]redis-cli -h 127.0.0.1 -p 6379 -a my_redisredis 127.0.0.1:6379> config get requirepass(error) ERR operation not permittedredis-cli -h 127.0.0.1 -p 6379 -a myRedisredis 127.0.0.1:6379> config get requirepass1) "requirepass"2) "myRedis"

In addition to setting a password with the-a parameter at login, you can log in without specifying a password and authenticate before performing the operation.

3.master configured the password, slave how to configure

If master is configured with a password, slave must also configure the appropriate password parameters otherwise it will not be able to replicate normally.
Locate the following line in the config file in slave, remove the comment, and change the password
