If an error is reported:

!!! WARNING The following tests failed:

* * [err]: Test replication partial resync: ok psync (diskless: yes, reconnect: 1) in tests/integration/replication-psync.tcl

Expected condition'[s-1 sync_partial_ok] > 0'to be true ([s-1 sync_partial_ok] > 0)

Change the tests/integration/replication-psync.tcl file:

Vi tests/integration/replication-psync.tcl

Change the number after the after in the code corresponding to the error report from 100 to 500. Personally, this parameter seems to be the number of milliseconds to wait.

As a high-speed memory key-value pair (Key-Value) database, Redis is widely used. If it is a remote connection, security must be taken into account. So how do you set up security for Redis?

Redis password management

one。 How to initialize the password for redis?

A total of 2 steps:

a. There is a parameter in the configuration file: requirepass this is the parameter to configure the redis access password.

Like requirepass test123.

b. Restart redis is required for the parameters in the configuration file to take effect. Vi / etc/redis.conf

two。 How do I configure a password without restarting redis?

a. Configure the password for requirepass in the configuration file (the password is still valid when redis is restarted).

# requirepass foobared

If it is modified to:

Requirepass test123

b. Enter redis to redefine parameters

View the current password:

[root@slaver251 redis-2.4.16] #. / src/redis-cli-p 6379

Redis 127.0.0.1 6379 > # p# paging title # e #

Redis 127.0.0.1 6379 > config get requirepass View password

1) "requirepass"

2) (nil)

Show that the password is empty

Then set the password:

Redis 127.0.0.1 6379 > config set requirepass test123

OK

Query the password again:

Redis 127.0.0.1 6379 > config get requirepass

(error) ERR operation not permitted

I made a mistake at this time!

Now all you need is password authentication.

Redis 127.0.0.1 6379 > auth test123

OK

Query the password again:

Redis 127.0.0.1 6379 > config get requirepass

1) "requirepass"

2) "test123"

The password has been changed.

When it is time to restart redis, the password will automatically take effect because the configuration parameters have been changed.

If the configuration parameter does not add a password, then the redis restart password will be equivalent to no setting.

three。 How do I log in to redis with a password?

a. Enter the password when you log in.

[root@slaver251 redis-2.4.16] #. / src/redis-cli-p 6379-a test123

Redis 127.0.0.1 6379 > # p# paging title # e #

Redis 127.0.0.1 6379 > config get requirepass

1) "requirepass"

2) "test123"

b. Log in before you verify:

[root@slaver251 redis-2.4.16] #. / src/redis-cli-p 6379

Redis 127.0.0.1 purl 6379 >

Redis 127.0.0.1 6379 > auth test123

OK

Redis 127.0.0.1 6379 > config get requirepass

1) "requirepass"

2) "test123"

Redis 127.0.0.1 purl 6379 >

four。 Master has a password, how to configure slave?

When master has a password to configure slave, the corresponding password parameters must also be configured accordingly. Otherwise, slave will not be able to copy normally.

The corresponding parameters are:

# masterauth

For example:

Masterauth mstpassword
