Redis advanced features 1

I. Security username and password)

Find requirepass in redis-conf and change it to requirepass *****.

There are two methods to use the password

1. Go to redis-cli and then auth ******

2. redis-cli-******

Ii. Master-slave Replication

1. The Master can have multiple Slave instances.

2. slave can be connected to the same master or slave.

3. master-slave replication does not block the master node. During data synchronization, the master node can continue to process requests.

4. Improve system scalability

Configure the redis-conf of slave and find the location:

650) this. width = 650; "title =" QQ20130921220701.png "src =" http://www.bkjia.com/uploads/allimg/131229/210453L62-0.png "alt =" 221520314.png"/>

To:

Slaveof192.168.88896379

Masterauth ******

Iii. Transaction Processing

Redis supports Simple transactions. After the multi command is started, the connection enters the transaction. Subsequent commands after the connection are not executed immediately, but are placed in the queue first. When the exec command is executed, redis executes commands in the queue sequentially.

The discard command clears the queue and rolls back the transaction.

However, it is worth noting that when an error occurs later, the executed command will not be rolled back.

For example:

650) this. width = 650; "title =" QQ20130921220701.png "alt =" 220742565.png" src = "http://www.bkjia.com/uploads/allimg/131229/210453C32-1.png"/>
