解压
# tar -zxvf redis-4.0.8.tar.gz -C /usr/local

创建集群配置文件夹
# mkdir -p /usr/local/redis/cluster-conf/7001
# mkdir -p /usr/local/redis/cluster-conf/7002
# cp /usr/local/redis/redis.conf /usr/local/redis/cluster-conf/7001
# cp /usr/local/redis/redis.conf /usr/local/redis/cluster-conf/7002


修改集群配置
vim /usr/local/redis/cluster-conf/7001/redis.conf

port 7001
daemonize yes
/var/run/redis-7001.pid
logfile "/usr/local/redis/cluster-conf/7001/redis.log"
dir /usr/local/redis/cluster-conf/7002/
cluster-enabled yes
cluster-config-file /usr/local/redis/cluster-conf/7001/nodes.conf
cluster-node-timeout 15000
appendonly yes
bind 0.0.0.0


vim /usr/local/redis/cluster-conf/7002/redis.conf

port 7002
daemonize yes
pidfile /var/run/redis-7002.pid
logfile "/usr/local/redis/cluster-conf/7002/redis.log"
dir /usr/local/redis/cluster-conf/7002/
cluster-enabled yes
cluster-config-file /usr/local/redis/cluster-conf/7002/nodes.conf
cluster-node-timeout 15000
appendonly yes
bind 0.0.0.0


远程拷贝redis
scp -r /usr/local/redis/ root@192.168.241.102:/usr/local/
scp -r /usr/local/redis/ root@192.168.241.103:/usr/local/


安装依赖
yum install -y gcc tcl ruby rubygems


安装redis
make install PREFIX=/usr/local/redis


错误
redis编译报致命错误：jemalloc/jemalloc.h：没有那个文件或目录

make MALLOC=libc


redis requires Ruby version >= 2.2.2的报错

启动服务
/usr/local/redis/bin/redis-server /usr/local/redis/cluster-conf/7001/redis.conf &
/usr/local/redis/bin/redis-server /usr/local/redis/cluster-conf/7002/redis.conf &




gem 安装 redis ruby 接口
# gem install redis


创建集群
# /usr/local/redis/src/redis-trib.rb create --replicas 1 192.168.241.101:7001 192.168.241.102:7001 192.168.241.103:7001 192.168.241.101:7002 192.168.241.102:7002 192.168.241.103:7002




查看节点信息
# /usr/loca/redis/bin/redis-cli -c -p 7001
127.0.0.1:7001> cluster nodes




配置选项选项值说明
daemonizeyes是否作为守护进程运行
pidfile/var/run/redis-7001.pid如以后台进程运行，则需指定一个pid 默认为/var/run/redis.pid
port7001监听端口，默认为6379注意：集群通讯端口值默认为此端口值+10000,如17111
cluster-config-file/usr/local/redis/cluster-conf/7001/nodes.conf集群配置文件(启动自动生成)，不用人为干涉
cluster-node-timeout15000节点互连超时时间。毫秒
appendonlyyes启用aof持久化方式
diryes打开redis集群
cluster-enabled/usr/local/redis/cluster-conf/7001节点数据持久化存放目录
