Redis集群安装

Redis集群安装文档

---

安装java环境

rpm -ivh jdk-8u112-linux-x64.rpm 

配置环境变量

JAVA_HOME=/usr/java/jdk1.8.0_112JRE_HOME=/usr/java/jdk1.8.0_112/jrePATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/binexport JAVA_HOME JRE_HOME

安装redis

• 下载redis并解压

cd /cluster/redis/mkdir downloadcd download/wget http://download.redis.io/releases/redis-3.2.5.tar.gz

• 创建redis所需的目录

mkdir redis_clustermkdir redis_cluster/datamkdir redis_cluster/logmkdir redis_cluster/conf

• 编译源码

cd /cluster/redis/download/redis-3.2.5makemake install PREFIX=/cluster/redis/redis_cluster/redis-3.2.5mkdir /cluster/redis/redis_cluster/data/6379mkdir /cluster/redis/redis_cluster/data/6380

• 添加conf文件
  6379 如下示例

vim /cluster/redis/redis_cluster/data/6379/redis-6379.conf port 6379bind 10.1.33.102cluster-enabled yescluster-config-file nodes-6379.confcluster-node-timeout 5000appendonly yesdaemonize yespidfile /var/run/redis-6379.piddir /cluster/redis/redis_cluster/data/6379dbfilename dump-6379.rdbappendfilename appendonly-6379.aoflogfile /cluster/redis/redis_cluster/log/redis-6379.log

6380 如下示例

port 6380bind 10.1.33.102cluster-enabled yescluster-config-file nodes-6380.confcluster-node-timeout 5000appendonly yesdaemonize yespidfile /var/run/redis-6380.piddir /cluster/redis/redis_cluster/data/6380dbfilename dump-6380.rdbappendfilename appendonly-6380.aoflogfile /cluster/redis/redis_cluster/log/redis-6380.log

• 安装集群环境

sudo yum -y install ruby ruby-devel rubygems rpm-build sudo gem install rediscp /cluster/redis/download/redis-3.2.5/src/redis-trib.rb /cluster/redis/redis_cluster/redis-3.2.5/bin/

• 启动redis

./redis-3.2.5/bin/redis-server conf/redis-6379.conf./redis-3.2.5/bin/redis-server conf/redis-6380.conf

• 创建redis cluster

  ./redis-3.2.5/bin/redis-trib.rb create --replicas 1 10.1.33.102:6379 10.1.33.103:6379 10.1.33.105:6379 10.1.33.102:6380 10.1.33.103:6380 10.1.33.105:6380

• 出现错误 Connection timed out

/usr/lib/ruby/gems/1.8/gems/redis-3.3.2/lib/redis/connection/ruby.rb:111:in `_write_to_socket': Connection timed out (Redis::TimeoutError) 

原因防火墙问题，需要彻底关闭防火墙

iptables -F/etc/init.d/iptables stopchkconfig iptables offiptables-save

重装gem到低版本

gem listsudo gem uninstall redis --version 3.3.2sudo gem install redis --version 3.0.0

• 启动redis集群

./redis-3.2.5/bin/redis-server conf/redis-6379.conf./redis-3.2.5/bin/redis-server conf/redis-6380.confps -ef|grep redis./redis-3.2.5/bin/redis-server conf/redis-6381.conf./redis-3.2.5/bin/redis-server conf/redis-6382.confps -ef|grep redis./redis-3.2.5/bin/redis-server conf/redis-6383.conf./redis-3.2.5/bin/redis-server conf/redis-6384.confps -ef|grep redis./redis-3.2.5/bin/redis-trib.rb create --replicas 1 10.1.33.102:6379 10.1.33.103:6381 10.1.33.105:6383 10.1.33.102:6380 10.1.33.103:6382 10.1.33.105:6384

• 常用操作
  查看哪些端口的节点是master，哪些端口的节点是slave

./redis-3.2.5/bin/redis-trib.rb check 10.1.33.105:6384

启动client

./redis-3.2.5/bin/redis-cli -c -h 10.1.33.102 -p 6379

使用info 或者 info replication查看本redis的信息
