redis5.0.7安裝及配置集群


1.安裝環境linux系統,時間2020年2月

2.官網下載https://redis.io/

3.解壓

tar -zxvf redis-5.0.7.tar.gz

4.配置文件

 1 //創建etc文件夾,bin文件夾
 2 [~]#cp redis.conf redis_copy.conf
 3 [~]#mv redis.conf ./etc/
 4 [~]#cd src
 5 [~]mv mkreleasehdr.sh   redis-check-aof redis-check-rdb redis-cli redis-server redis-trib.rb redis-benchmark ../bin/
 6 //創建8000-8005文件夾,在etc
 7 [~]#cd ../etc
 8 [~]#mkdir 8000
 9 [~]#mkdir 8001
10 [~]#mkdir 8002
11 [~]#mkdir 8003
12 [~]#mkdir 8004
13 [~]#mkdir 8005
14 [~]cp ../redis.conf ./8000/

4.1配置8000文件夾下的redis.conf,並復制到其他文件下

1 port 8000 //端口
2 bind 本機ip //默認ip為127.0.0.1 需要改為其他節點機器可訪問的ip 否則創建集群時無法訪問對應的端口,無法創建集群 ,或者注釋掉
3 daemonize yes //redis后台運行 
4 pidfile /var/run/redis_8000.pid //pidfile文件對應8000, 
5 cluster-enabled yes //開啟集群 把注釋#去掉 
6 cluster-config-file nodes_8000.conf //集群的配置 配置文件首次啟動自動生成 80002 把注釋#去掉 
7 cluster-node-timeout 15000 //請求超時 默認15秒,可自行設置  把注釋#去掉 
8 appendonly yes //aof日志開啟 有需要就開啟,它會每次寫操作都記錄一條日志

5.編寫啟動sh和停止sh

redis官網:The first example, that is, the cluster creation, will be shown using both redis-cli in Redis 5 and redis-trib in Redis 3 and 4. However all the next examples will only use redis-cli, 
since as you can see the syntax is very similar, and you can trivially change one command line into the other by using redis-trib.rb help to get info about the old syntax.
Important: note that you can use Redis 5 redis-cli against Redis 4 clusters without issues if you wish. 從5.0之后,可以不用ruby啟動集群,3,4還是要的。例如:
redis-cli --cluster create 127.0.0.1:7000 127.0.0.1:7001 \127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 \--cluster-replicas 1
//編寫一個簡單的startall.sh啟動
[~]#touch startall.sh
[~]#vim startall.sh
cd /home/software/redis-5.0.7/bin/
./redis-server ../etc/8000/redis.conf
./redis-server ../etc/8001/redis.conf
./redis-server ../etc/8002/redis.conf
./redis-server ../etc/8003/redis.conf
./redis-server ../etc/8004/redis.conf
./redis-server ../etc/8005/redis.conf
[~]#chmod +x startall.sh//給這個執行的權限
[~]#bash startall.sh
[~]#ps -aux | grep redis //查看啟動狀態
//編寫一個停止sh
[~]#touch shutdown-all.sh
[~]#vim shutdown-all.sh
bin/redis-cli -p 8000 shutdown
bin/redis-cli -p 8001 shutdown
bin/redis-cli -p 8002 shutdown
bin/redis-cli -p 8003 shutdown
bin/redis-cli -p 8004 shutdown
bin/redis-cli -p 8005 shutdown

6.創建集群

[~]#./redis-cli --cluster create 127.0.0.1:8000 127.0.0.1:8001 127.0.0.1:8002 127.0.0.1:8003 127.0.0.1:8004 127.0.0.1:8005 --cluster-replicas 1

7.測試

[~]#redis-cli -c -p 8000
[~]#cluster info
