Foreword:

My version is 2.6.9. I have the master and follower of auth. I haven't found it for a long time on the Internet. Finally, I found a way to be the master and follower on the official website. It's actually very simple.

If you are a master and slave with verification, then you need to use keyFile verification, according to the official.

When running with authorization enabled, in master-slave deployments configure a keyFile so that slave mongod instances 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, which is very simple (but it hurts if we don't know)

1. You can use openssl to generate a random key

Openssl rand-base64 741 > > key1

[root@localhost data2] # openssl rand-base64 741

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

[root@localhost mongodb] # ll

Total 76

Drwxr-xr-x. 2 root root 4096 May 5 01:20 bin

-rw-r--r--. 1 1046 1046 34520 Mar 23 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

3. Modify the configuration file of mongodb.conf, remove the comments on keyFile options, and fill in the current key1 path.

KeyFile=/usr/local/services/mongodb/key1

4. You can start to be the master and follower now.

1) modify the slave mongodb.conf configuration file

Master=false

Slave=true

Source= main library IP

Slavedelay=60

Autoresync=true

2) start the slave library
