阿里云环境迁移记录 - Redis集群搭建

Redis集群须要至少6个节点，3主3从，因为服务器资源有些，这里使用3台机器6个端口实现。

Part1 redis依赖安装

#########################

1. yum install gcc

2. tcl安装

   wget http://downloads.sourceforge.net/tcl/tcl8.6.1-src.tar.gz
   rsync -e 'ssh -p 20462' tcl8.6.1-src.tar.gz root@172.36.27.72:/opt/install/
   rsync -e 'ssh -p 20462' tcl8.6.1-src.tar.gz root@172.36.27.72:/opt/install/
   sudo tar xzvf tcl8.6.1-src.tar.gz -C /usr/local/
   cd /usr/local/tcl8.6.1/unix/
   ./configure
   make && make install

3. ruby安装

   wget http://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.5.tar.gz
   rsync -e 'ssh -p 20462' ruby-2.3.5.tar.gz root@172.36.27.71:/opt/install/
   rsync -e 'ssh -p 20462' ruby-2.3.5.tar.gz root@172.36.27.72:/opt/install/
   tar -xvf ruby-2.3.5.tar.gz
   cd ruby-2.3.5
   ./configure  --prefix=/opt/ruby
   make && make install
   ln -s /opt/ruby/bin/ruby /usr/bin/ruby
   ln -s /opt/ruby/bin/gem /usr/bin/gem

4. rubygem安装

   wget http://rubygems.org/downloads/redis-4.0.1.gem
   rsync -e 'ssh -p 20462' redis-4.0.1.gem root@172.36.27.71:/opt/install/
   rsync -e 'ssh -p 20462' redis-4.0.1.gem root@172.36.27.72:/opt/install/
   gem install -l redis-4.0.1.gem

5. yum -y install zlib-devel

   进入ruby源码文件夹,安装ruby自身提供的zlib包
   cd ruby-2.3.5/ext/zlib
   ruby ./extconf.rb
   make
   make install

Part2 redis下载安装

#########################

wget http://download.redis.io/releases/redis-4.0.0.tar.gz
tar xzf redis-4.0.0.tar.gz
cd redis-4.0.0
#make（make MALLOC=libc）
cd src/        
make test 
make install

Part3 redis集群搭建

#########################
redis集群的最小单元是3主3从，即6个节点，这里咱们用三台物理机，6个端口实现，
三主:6239
三从:6339
host1: 172.36.27.72
host2: 172.36.27.71
host1: 172.36.27.70

分别在3台机器上建立端口目录:

mkdir -p /data/redis-cluster/logs
mkdir -p /data/redis-cluster/{6239,6339}
mkdir -p /data/redis-cluster/{6239,6339}
mkdir -p /data/redis-cluster/{6239,6339}

copy配置文件并修改

cp /opt/install/redis-4.0.0/redis.conf /data/redis-cluster/6239/node_6239.conf
cp /opt/install/redis-4.0.0/redis.conf /data/redis-cluster/6339/node_6339.conf

vim node_6239.conf

bind 0.0.0.0
port 6239
daemonize yes
pidfile /var/run/redis_6239.pid
logfile "/data/redis-cluster/logs/6239.log"
dir /data/redis-cluster/6239/
cluster-enabled yes
cluster-config-file  cluster-node-6239.conf
cluster-node-timeout 15000
masterauth Password
requirepass Password

vim node_6339.conf

bind 0.0.0.0
port 6339
daemonize yes
pidfile /var/run/redis_6339.pid
logfile "/data/redis-cluster/logs/6339.log"
dir /data/redis-cluster/6339/
cluster-enabled yes
cluster-config-file cluster-node-6339.conf
cluster-node-timeout 15000
masterauth Password
requirepass Password

#vim编辑替换
:%s/6239/6339/g

#启动3台服务器上的6个redis节点，建立集群，每一个节点一个副本

redis-server /data/redis-cluster/6239/node_6239.conf
redis-server /data/redis-cluster/6339/node_6339.conf

cd /opt/install/redis-4.0.0
./redis-4.0.0/src/redis-trib.rb create  --replicas 1 172.36.27.72:6239  172.36.27.72:6339 172.36.27.71:6239  172.36.27.71:6339 172.36.27.70:6239  172.36.27.70:6339

##检查集群完整性

cd /opt/install/redis-4.0.0
./src/redis-trib.rb check 172.36.27.72:6339

##登陆查看集群状态

redis-cli -h 172.36.27.72 -p 6239 -a Password
> cluster info

##redis重启
//中止某个节点服务

redis-cli  -h 172.36.27.71 -p 6239 -a Password shutdown 
redis-cli  -h 172.36.27.70 -p 6339 -a Password shutdown

//启动某个节点服务

redis-server /data/redis-cluster/6239/node_6239.conf 
redis-server /data/redis-cluster/6339/node_6339.conf

###动态修改密码写入文件

redis-cli -h 172.36.27.70 -p 6239 -c
config set masterauth xxx
config set requirepass xxx
config rewrite

###spring boot整合配置

spring.redis.database=0
spring.redis.cluster.nodes=172.36.27.72:6239,172.36.27.72:6339,172.36.27.71:6239,172.36.27.71:6339,172.36.27.70:6239,172.36.27.70:6339
spring.redis.password=Password
spring.redis.pool.max-active=8  
spring.redis.pool.max-wait=-1  
spring.redis.pool.max-idle=8  
spring.redis.pool.min-idle=0  
spring.redis.timeout=0
