Sekurang-kurangnya harus ada tiga nod dalam kelompok dan setiap nod mempunyai nod sandaran. 6 pelayan diperlukan.
Jika syarat terhad, anda boleh membina kluster teragih pseudo Langkah berikut adalah untuk membina kluster redis dengan 6 nod pada pelayan Linux.
Direktori baharu: mkdir /usr/local/redis-cluster
wget http://download.redis.io/releases/redis-5.0.0.tar.gz tar xzf redis-5.0.0.tar.gz cd redis-5.0.0 make make install prefix=/usr/local/redis
/root/software/redis/redis-cluster-conf/7001/redis.confSesetengah operasi Perintah adalah untuk rujukan sahaja:/root/software/redis /redis-cluster-conf/ 7002/redis.conf
/root/software/redis/redis-cluster-conf/7003/redis.conf
/root/software/redis/redis-cluster-conf/7004 /redis.conf
/root/software/redis/redis-cluster-conf/7005/redis.conf
/root/software/redis/redis-cluster-conf/7006/redis.conf
cp redis.conf /usr/local/redis/bin cd /usr/local/redis/ cp -r bin ../redis-cluster/redis01 cd /usr/local/redis-cluster/redis01 rm dump.rdb #删除快照 vim redis.confKandungan fail konfigurasi ialah:
port 7001 #端口 cluster-enabled yes #启用集群模式 cluster-config-file nodes.conf cluster-node-timeout 5000 #超时时间 appendonly yes daemonize yes #后台运行 protected-mode no #非保护模式 pidfile /var/run/redis_7001.pid bind 172.20.10.7 #127.0.0.1改为本机ip地址,可用ifconfig查看ipPort dan pidfile perlu dilaraskan mengikut folder. Buat baki 5 kejadian:
[root@master redis-cluster]# cp -r redis01/ redis02 [root@master redis-cluster]# cp -r redis01/ redis03 [root@master redis-cluster]# cp -r redis01/ redis04 [root@master redis-cluster]# cp -r redis01/ redis05 [root@master redis-cluster]# cp -r redis01/ redis06Ubah suai port dan pidfile di bawah redis.conf masing-masing redis02 ~ redis06
Buat fail kelompok dan mulakan enam redis pada masa yang sama
vim startall.sh
Tambah kandungan berikut:
cd redis01 ./redis-server redis.conf cd .. cd redis02 ./redis-server redis.conf cd .. cd redis03 ./redis-server redis.conf cd .. cd redis04 ./redis-server redis.conf cd .. cd redis05 ./redis-server redis.conf cd .. cd redis06 ./redis-server redis.conf cd ..
dan kemudian laksanakan
untuk menjadikan menjadi fail boleh laku chmod u+x start-all.sh
start-all.sh
dan mulakannya dalam direktori semasa:
./startall.sh

ps aux|grep redis

chmod u+x shutdown.sh
Rasmi: /usr/local/redis-cluster/redis-cli -a xxx -c -h 192.168.5.100 -p 8001
Petua: - kata laluan pelayan akses, -c bermaksud mod kluster, -h Nyatakan alamat ip, -p menentukan nombor port
