redis3.2集群搭建

redis 集群

在一臺機器上搭建redis集群 redis版本3.2

我這也是需要搭建然後網上找文檔然最後總結的
參考:https://blog.csdn.net/u012042021/article/details/72818759

1,解壓源碼包安裝redis

#安裝需要的一些包
yum install ruby rubygem openssl 

#此步安裝時候，是沒有輸出的，只要不報錯慢慢等待就好了或者加 -V 參數看過程
gem install redis --version 3.0.0

#解壓安裝
tar xf redis-3.2.9.tar.gz
cd redis-3.2.9
make
make install PREFIX=/usr/local/redis #把編譯好的redis命令安裝到這個目錄下面

2，配置redis節點；redis3.x 最少需要6個節點[3主3從的模式]</p>

#配置節點目錄
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

#節點配置文件
cd /opt/redis/7000
vim redis.conf
bind 192.168.16.186 127.0.0.1 #這裏可以多個ip用空格分開
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"
其他幾個節點的配置文件和這個一樣就行，需要註意需要改動對應端口和一些文件名稱

#創建日誌目錄
mkdir /var/log/redis

#啟動各節點
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,創建集群

#進去源碼包目錄下src目錄下面，執行集群創建
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臺機器搭建集群
每臺3個節點；配置大同小異這裏就不在貼出過程了
1，同樣道理安裝不變，配置節點每臺為3個就行，2臺機器6個節點即可；端口一樣不一樣都可以
2，配置文件bind的IP地址修改，兩臺機器要互通
3，創建集群時在2臺機器任意一臺即可，註意節點地址和端口的變化
