redis3.2集群搭建

Posted 2020-11-06

在一台机器上搭建redis集群 redis版本3.2

我这也是需要搭建然后网上找文档然最后总结的
参考:https://blog.csdn.net/u012042021/article/details/72818759

1,解压源码包安装redis

#安装需要的一些包
yum install ruby rubygem openssl 

#此步安装时候，是没有输出的，只要不报错慢慢等待就好了或者加 -V 参数看过程
gem install redis --version 3.0.0

#解压安装
tar xf redis-3.2.9.tar.gz
cd redis-3.2.9
make
make install PREFIX=/usr/local/redis #把编译好的redis命令安装到这个目录下面

2，配置redis节点；redis3.x 最少需要6个节点[3主3从的模式]</p>

#配置节点目录
mkdir -p /opt/redis/ && cd /opt/redis
mkdir 7000 7001 7002 7003 7004 7005
cp -rf /usr/local/redis/bin 7000
cp -rf /usr/local/redis/bin 7001
cp -rf /usr/local/redis/bin 7002
cp -rf /usr/local/redis/bin 7003
cp -rf /usr/local/redis/bin 7004
cp -rf /usr/local/redis/bin 7005

#节点配置文件
cd /opt/redis/7000
vim redis.conf
bind 192.168.16.186 127.0.0.1 #这里可以多个ip用空格分开
port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-require-full-coverage no
appendonly yes
pidfile /var/run/redis_7000.pid
logfile /var/log/redis/redis_7000.log
dbfilename dump_7000.rdb
appendfilename "appendonly_7000.aof"
其他几个节点的配置文件和这个一样就行，需要注意需要改动对应端口和一些文件名称

#创建日志目录
mkdir /var/log/redis

#启动各节点
cd /opt/redis/7000
./bin/redis-server ./redis.conf
cd /opt/redis/7001
./bin/redis-server ./redis.conf
cd /opt/redis/7002
./bin/redis-server ./redis.conf
cd /opt/redis/7003
./bin/redis-server ./redis.conf
cd /opt/redis/7004
./bin/redis-server ./redis.conf
cd /opt/redis/7005
./bin/redis-server ./redis.conf

3,创建集群

#进去源码包目录下src目录下面，执行集群创建
cd redis-3.2.9/src/
./redis-trib.rb create --replicas 1 192.168.16.186:7000 192.168.16.186:7001 192.168.16.186:7002 192.168.16.186:7003 192.168.16.186:7004 192.168.16.186:7005

2台机器搭建集群
每台3个节点；配置大同小异这里就不在贴出过程了
1，同样道理安装不变，配置节点每台为3个就行，2台机器6个节点即可；端口一样不一样都可以
2，配置文件bind的IP地址修改，两台机器要互通
3，创建集群时在2台机器任意一台即可，注意节点地址和端口的变化
