1、下载redis3.2.3

wget http://download.redis.io/releases/redis-3.2.3.tar.gz

tar -zxvf redis-3.2.3.tar.gz

cd redis-3.2.3

make

make test //检查一下 看有没有问题

make install

安装完之后,会在src目录下生成几个可执行文件,分别是mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server。其中redis-server是启动Redis服务的,redis-cli是进入Redis客户端的。

mkdir etc

mkdir bin

mv redis.conf etc/

mv sentinel.conf etc/

mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-sentinel redis-server redis-trib.rb redis-cli ../bin

cp -R /usr/local/jenkins/redis/redis-3.2.3 /usr/local/jenkins/redis/redis-master-3.2.3

cp -R /usr/local/jenkins/redis/redis-3.2.3 /usr/local/jenkins/redis/redis-slave-3.2.3

2、配置主从redis

cd  /usr/local/jenkins/redis/redis-master-3.2.3/etc/

cp redis.conf master.conf

cd  /usr/local/jenkins/redis/redis-slave-3.2.3/etc/

cp redis.conf slave_6380.conf

cp redis.conf slave_6381.conf

mkdir  /usr/local/jenkins/redis/redis-master-3.2.3/logs

mkdir  /usr/local/jenkins/redis/redis-master-3.2.3/run

mkdir  /usr/local/jenkins/redis/redis-slave-3.2.3/logs

mkdir  /usr/local/jenkins/redis/redis-slave-3.2.3/run

修改主配置文件master.conf

port 6379

pidfile /usr/local/jenkins/redis/redis-master-3.2.3/run/redis_6379.pid

# slaveof <masterip> <masterport>

logfile "/usr/local/jenkins/redis/redis-master-3.2.3/logs/redis.master.log"

requirepass 123456

daemonize yes

bind 0.0.0.0

masterauth 123456

 

修改从配置文件slave_6380.conf(slave_6381.conf)

port 6380

pidfile /usr/local/jenkins/redis/redis-slave-3.2.3/run/redis_6380.pid

slaveof 127.0.0.1 6379

logfile "/usr/local/jenkins/redis/redis-slave-3.2.3/logs/redis.slave6380.log"

requirepass 123456

daemonize yes

bind 0.0.0.0

masterauth 123456

 

3、启动redis

./redis-server /usr/local/jenkins/redis/redis-master-3.2.3/etc/master.conf 

 

 

./redis-server /usr/local/jenkins/redis/redis-slave-3.2.3/etc/slave_6380.conf 

./redis-server /usr/local/jenkins/redis/redis-slave-3.2.3/etc/slave_6381.conf

 

 

主redis打印的日志

 

 

 

 

 

启动哨兵

 ./redis-sentinel /usr/local/jenkins/redis/redis-slave-3.2.3/etc/sentinel_26379.conf

 ./redis-sentinel /usr/local/jenkins/redis/redis-slave-3.2.3/etc/sentinel_26380.conf

 ./redis-sentinel /usr/local/jenkins/redis/redis-slave-3.2.3/etc/sentinel_26381.conf

 

sentinel_26379.conf配置文件

port 26379

dir /usr/local/jenkins/redis/redis-sentinel-3.2.3/tmp26379

daemonize yes

logfile "/usr/local/jenkins/redis/redis-sentinel-3.2.3/logs/redis.sentinel26379.log"

sentinel monitor mymaster 192.168.1.135 6379 1

sentinel auth-pass mymaster 123456

sentinel down-after-milliseconds mymaster 30000

sentinel parallel-syncs mymaster 1

sentinel failover-timeout mymaster 180000

 

 

查看信息:

redis-cli -h 127.0.0.1 -p 6379 -a 123456 info replication

redis-cli -h 127.0.0.1 -p 6380 -a 123456 info replication

 

用redis-cli工具登录其中一个哨兵

./redis-cli -p 26379

连接成功后运行如下命令

sentinel master mymaster

 

4、测试

登录主redis

 ./redis-cli -h 127.0.0.1 -p 6379 -a 123456

set name zhangsan

set addr shanghai

set curTime 2016-07-11

登录从reids

./redis-cli -h 127.0.0.1 -p 6380

get name

get addr

get curTime

5、测试主redis宕机,切换从reids为主

关闭主redis

./redis-cli  -h 127.0.0.1 -p 6379 -a 123456 shutdown

切换从reids为主reids

./redis-cli -p 6380 -a 123456 slaveof NO ONE

测试从redis是否切换从主redis是否成功

./redis-cli -h 127.0.0.1 -p 6380 -a 123456

set name zhangsan
