redis主从配置

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
