Redis Master-Slave deployment

Master:192.168. 30.131 Slave01: 192.168. 30.132 SLAVE02: 192.168. 30.134

1) Download the package

Used here: redis-3.0.3.tar.gz

2) Redis Installation

TARZXF redis-3.0. 3 . TAR.GZMV Redis-3.0. 3  /data/rediscd  /data/redismake&& make installmkdir  /data/redis _6379

3) Redis Configuration

Locate the configuration file/data/redis/redis.conf

Modify the following content:

daemonize  No change to Yes #启动后台运行dir. /change to/data/  redis_6379   #数据目录slaveof192.168.  30.131  6379   #同步master, set this parameter only from the

4) Redis Boot

Cp/data/redis/util/redis_init_scriptetc/init.d/redis

and modified as follows:

Conf=/data/redis/redis.conf

Pidfile=/var/run/redis.pid

Serviceredis start

5) Redis Master-Slave test

Redis-cli

127.0.0.1:6379>set name Yang

Ok

127.0.0.1:6379>get Name

"Yang"

Summary: Disadvantage for single point of failure

Redis Sentinel Deployment

Architecture diagram:

Modify the file/data/redis/sentinel.conf as follows:

Sentialmontinelmymastar 192.168.30.131 2

The format is as follows:

Sentialmontinel Monitor Host name (optionally defined) main data IP port number quorum value

Quorum value calculation method: Sentinel node number/2+1

Summary: Solve the single point of failure, the disadvantage is that each database still has all the data in the cluster, resulting in the total data storage of the cluster is limited to the smallest available storage memory database node, the formation of cask effect.

/data/redis/src/redis-sentinel/data/redis/sentinel.conf

Redis Persistence

Two types of persistence: Rdb and AoF

RDB: The specified rule "timed" stores the in-memory data on the hard disk;

AOF: The command itself is recorded after each execution of the command.

RDB settings (enabled by default):

Automatic snapshots based on configuration rules

User executes save or bgsave command

Execute Flushall command

When performing replication (master-slave)

AOF settings:

Turn on the appendonly parameter

Specify save file Appendfilename parameter
