配置域名

192.168.241.101 paascloud-redis-001

192.168.241.102 paascloud-redis-002

192.168.241.103 paascloud-redis-003

下载

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

解压

# 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

# 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/ [email protected]:/usr/local/
scp -r /usr/local/redis/ [email protected]:/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
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		启用aof持久化方式
dir		打开redis集群
cluster-enabled	/usr/local/redis/cluster-conf/7001	节点数据持久化存放目录
