VI. Redis sentinel deployment

Create a redis-sentinel directory

Mkdir-pv / app/codis/sentinel/ {27001pr 27002}

Configure the sentinel file

Vi / app/codis/sentinel/27001/sentinel-27001.conf

Bind 0.0.0.0

Protected-mode no

Port 27001

Dir / app/codis/sentinel/27001/

Vi / app/codis/sentinel/27002/sentinel-27002.conf

Bind 0.0.0.0

Protected-mode no

Port 27002

Dir / app/codis/sentinel/27002/

Start the sentinel service

Cp/app/gopkg/src/github.com/CodisLabs/codis/extern/redis-3.2.8/src/redis-sentinel/app/codis/bin/

/ app/codis/bin/redis-sentinel / app/codis/sentinel/27001/sentinel-27001.conf &

/ app/codis/bin/redis-sentinel / app/codis/sentinel/27002/sentinel-27002.conf &

7. Use codis-fe to manage codis cluster environment

1.codis-fe management interface

Http://172.16.40.131:18090

Add codis-proxy:

Use commands to add

[root@codis-02 bin] #. / codis-admin-- dashboard=127.0.0.1:18080-- create-proxy-x 127.0.0.1 purl 11080

Interface addition can also be used.

Add codis-server

NEW GROUP first

Add one master and two slaves

Add two groups

The above can also be added with commands.

Add redis-sentinel

Command increment

[root@codis-02bin] # / codis-admin-- dashboard=172.16.40.131:18080-- sentinel-add-- addr=172.16.40.131:27002

Assign slot

Slot: a data slot, a unit for slicing data between codis-server; it is recommended that data slots be evenly divided into multiple group

Add redis-sentinel to the codis-fe management interface and synchronize. After synchronization, the redis-sentinel configuration file will be updated.

Root@codis-02bin] # cat / app/codis/sentinel/27001/sentinel-27001.conf

Bind 0.0.0.0

Protected-mode no
