redis主從配置

一、下載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 //檢查一下 看有沒有問題
make install

安裝完以後，會在src目錄下生成幾個可執行文件，分別是mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server。其中redis-server是啓動Redis服務的，redis-cli是進入Redis客戶端的。

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

二、配置主從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

修改從配置文件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

三、啓動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打印的日誌

啓動哨兵

./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工具登陸其中一個哨兵

./redis-cli -p 26379

鏈接成功後運行以下命令

sentinel master mymaster

四、測試
登陸主redis

./redis-cli -h 127.0.0.1 -p 6379 -a 123456
set name zhangsan
set addr shanghai
set curTime 2016-07-11

登陸從reids

./redis-cli -h 127.0.0.1 -p 6380
get name
get addr
get curTime

五、測試主redis宕機，切換從reids爲主
關閉主redis

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

切換從reids爲主reids

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

測試從redis是否切換從主redis是否成功

./redis-cli -h 127.0.0.1 -p 6380 -a 123456
set name zhangsan
