centos7.3安装redis4.0.8主3从集群

配置域名

192.168.241.101 paascloud-redis-001
192.168.241.102 paascloud-redis-002

下载

1	wget http://download.redis.io/releases/redis-4.0.8.tar.gz

解压

1 2	# tar -zxvf redis-4.0.8.tar.gz -C /usr/local # mv redis-4.0.8 redis

创建集群配置文件夹

1 2 3 4

# 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

1 2 3 4 5 6 7 8 9 10

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

1 2 3 4 5 6 7 8 9 10

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

1 2	scp -r /usr/local/redis/ [email protected]:/usr/local/ scp -r /usr/local/redis/ [email protected]:/usr/local/

安装依赖

1	yum install -y gcc tcl ruby rubygems

安装redis

1	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

1	make MALLOC=libc

• redis requires Ruby version >= 2.2.2的报错

1	http://blog.csdn.net/liu_zhaoming/article/details/79354420

启动服务

1 2	/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

1	# gem install redis

创建集群

1	# /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

1 2	# /usr/loca/redis/bin/redis-cli -c -p 7001 127.0.0.1:7001> cluster nodes

这里写图片描述

配置选项	选项值	说明
daemonize	yes	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
port	7001	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-timeout	15000	节点互连超时时间。毫秒
appendonly	yes	启用aof持久化方式
dir	yes	打开redis集群
cluster-enabled	/usr/local/redis/cluster-conf/7001	节点数据持久化存放目录
