MongoDB does have authentication (auth) of master and slave

Objective:

My version is 2.6.9, has Auth's master and slave, found in the internet for a long time have not found, finally found in the official online method, in fact very simple

If you do have a verified master-slave, then need to use the KeyFile verification, the official said

When running withauthorizationenabled, in Master-slavedeployments Configure a keyFileSo that slave mongodinstances can authenticate and communicate with the master mongod instance.

To enable authentication and configure the keyFile Add the following option to your configuration file:

Keyfile=/srv/mongodb/keyfile

So we need to configure KeyFile, the configuration is very simple (but if you don't know the egg hurts)

1. You can use OpenSSL to generate a random key

OpenSSL rand-base64 741 >>key1

2. Place key in the MongoDB directory and set 0600 permissions

[email protected] mongodb]# ll
Total 76
Drwxr-xr-x. 2 root root 4096 May 5 01:20 bin
-rw-r--r--. 1 1046 1046 34520 Mar 07:49 gnu-agpl-3.0
-RW-------. 1 root root 1004 May 6 04:43 Key1
-rw-r--r--. 1 root root 1620 May 6 04:55 mongodb.conf

-rw-r--r--. 1 1046 1046 17793 Mar 07:49 third-party-notices

3, modify the mongodb.conf configuration file, remove the KeyFile option Comment, and fill in the current Key1 path

Keyfile=/usr/local/services/mongodb/key1

4. Now it's time to start

1) Modify the mongodb.conf configuration file from the library

Master=false

Slave=true

source= Main Library IP

Slavedelay=60

Autoresync=true

2) Start from library
