redis集群部署

Redis集群部署

1. 编译安装

# cd /usr/local/src/

# wget http://download.redis.io/releases/redis-5.0.0.tar.gz

# tar zxvf redis-5.0.0.tar.gz

# apt-get update && apt-get install -y gcc automake make# cd redis-5.0.0 && make && make install

# cp ./src/redis-server /usr/bin/

# cp ./src/redis-cli /usr/bin/

2. 创建服务启停脚本(如果需要)

# cp ./utils/redis_init_script /etc/init.d/redisd

# service redisd start

3. 创建目录及配置文件

# mkdir /tmp/redis-cluster/{7000,7001,7002,7003,7004,7005}/log -pv
 

# cp /usr/local/src/redis-5.0.0/redis.conf /data/redis-cluster/7000/redis.conf

# cd /data/redis-cluster/ && cat 7000/redis.conf

修改其他端口配置文件

# cp 7000/redis.conf 7001/

# cp 7000/redis.conf 7002/

# cp 7000/redis.conf 7003/

# cp 7000/redis.conf 7004/

# cp 7000/redis.conf 7005/

# sed -i 's/7000/7001/g' 7001/redis.conf

# sed -i 's/7000/7002/g' 7002/redis.conf

# sed -i 's/7000/7003/g' 7003/redis.conf

# sed -i 's/7000/7004/g' 7004/redis.conf

# sed -i 's/7000/7005/g' 7005/redis.conf

4. 调整下内存分配使用方式并使其生效

#此参数可用的值为0,1,2 

#0表示当用户空间请求更多的内存时，内核尝试估算出可用的内存 

#1表示内核允许超量使用内存直到内存用完为止

 #2表示整个内存地址空间不能超过swap+(vm.overcommit_ratio)%的RAM值

 echo "vm.overcommit_memory=1">>/etc/sysctl.conf

sysctl -p

5. 制作启动脚本

# cat start-redis-cluster.sh
#!/bin/bash
cd /data/redis-cluster
cd 7000 && /usr/bin/redis-server /data/redis-cluster/7000/redis.confcd 
../7001 && /usr/bin/redis-server /data/redis-cluster/7001/redis.confcd
 ../7002 && /usr/bin/redis-server /data/redis-cluster/7002/redis.confcd 
../7003 && /usr/bin/redis-server /data/redis-cluster/7003/redis.confcd
 ../7004 && /usr/bin/redis-server /data/redis-cluster/7004/redis.confcd
 ../7005 && /usr/bin/redis-server /data/redis-cluster/7005/redis.conf

6. 启动服务

# bash start-redis-cluster.sh

# ps -ef|grep redis

root     30192     1  0 06:54 ?        00:00:04 /usr/bin/redis-server 
0.0.0.0:7000 [cluster]

root     30194     1  0 06:54 ?        00:00:05 /usr/bin/redis-server 
0.0.0.0:7001 [cluster]

root     30201     1  0 06:54 ?        00:00:04 /usr/bin/redis-server 
0.0.0.0:7003 [cluster]

root     30206     1  0 06:54 ?        00:00:05 /usr/bin/redis-server 
0.0.0.0:7004 [cluster]

root     30211     1  0 06:54 ?        00:00:04 /usr/bin/redis-server 
0.0.0.0:7005 [cluster]

7. 创建集群

# redis-cli --cluster create 10.20.71.215:7000 10.20.73.204:7001 
10.20.71.67:7002 10.20.71.215:7003 10.20.73.204:7004 10.20.71.67:7005 --cluster-replicas 1 -a AuDdQdpuEZpXgNthP6CjYjPb

8. 查看集群信息

root@mgo-db01cn-t001:/usr/local/src/redis-5.0.0
# redis-cli -c -p 7000127.0.0.1:7000> auth AuDdQdpuEZpXgNthP6CjYjPb

OK

127.0.0.1:7000> cluster nodes

控制台信息显示: 当前集群中存在3个主节点和3个从节点，说明我们的集群已经搭建成功 至此，Redis Cluster集群就搭建完成了!

9. 测试数据

root@mgo-db01cn-t001:~# redis-cli -h 10.20.73.204 -p 7001

10.20.73.204:7001> auth AuDdQdpuEZpXgNthP6CjYjPb

OK

10.20.73.204:7001>

10.20.73.204:7001>

10.20.73.204:7001>

10.20.73.204:7001> 
set name shuke

OK

10.20.73.204:7001>

10.20.73.204:7001>

10.20.73.204:7001>

10.20.73.204:7001> get name

"shuke"

10. cluster saveconfig

将节点的配置文件保存到硬盘里面.

试一下：

127.0.0.1:7009> cluster saveconfig

OK

ok说明成功了,它会覆盖配置文件夹里的nodes.conf文件.这样做是为了某种情况下nodes文件丢失,这样就会生成一个最新的节点配置文件。

Tips :

1.如果想重新创建集群，需要登录到每个节点，执行flushdb，然后执行cluster reset，重启节点;
