Redis 集群单机安装和多服务器安装过程(一)
作者:互联网
本次安装的是编辑版的redis,分别从单机安装和多服务器安装全过程,不论是单机还是多机安装都需要进行如下操作,安装redis,下载地址:Redis
1.创建安装目录
cd /app/cmw
mkdir redis
cd redis
2.解压安装包
tar -xvzf redis-6.2.6.tar.gz
cd redis-6.2.6
3.授予src目录下文件执行权限
chmod +x -R src
4.安装redis
make MALLOC=libc
make install
2.单机安装三主三从
1.创建集群文件夹
cd /app/cmw/redis
mkdir cluster
cd cluster
2.创建配置、数据、日志目录
mkdir -p data conf logs scripts
3.创建节点7001配置文件
cd conf
vi redis-7001.conf
在该配置文件中输入如下信息
port 7001
daemonize yes
dir "/app/cmw/redis/cluster/data"
logfile "/app/cmw/redis/cluster/logs/7001.log"
#dbfilename不能配置为路径
dbfilename "dump-7001.rdb"
cluster-enabled yes
cluster-config-file nodes-7001.conf
#是否需要每个节点都可用,集群才算可用,关闭
cluster-require-full-coverage no
4.复制节点7001到7002、7003、7004、7005、7006
sed "s/7001/7002/g" redis-7001.conf >redis-7002.conf
sed "s/7001/7003/g" redis-7001.conf >redis-7003.conf
sed "s/7001/7004/g" redis-7001.conf >redis-7004.conf
sed "s/7001/7005/g" redis-7001.conf >redis-7005.conf
sed "s/7001/7006/g" redis-7001.conf >redis-7006.conf
5.启动redis服务
redis-server redis-7001.conf
redis-server redis-7002.conf
redis-server redis-7003.conf
redis-server redis-7004.conf
redis-server redis-7005.conf
redis-server redis-7006.conf
后续启动可以写一个批量启动的脚本,放在文档末尾
6.构建集群
redis-cli -p 7001 cluster meet 192.168.245.135 7002
redis-cli -p 7001 cluster meet 192.168.245.135 7003
redis-cli -p 7001 cluster meet 192.168.245.135 7004
redis-cli -p 7001 cluster meet 192.168.245.135 7005
redis-cli -p 7001 cluster meet 192.168.245.135 7006
查看节点以及结果
redis-cli -p 7001 cluster nodes

7.设置主从关系将7001:7004、7002:7005、7003:7006做为主:从关系节点
redis-cli -p 7004 cluster replicate 4228b57d5a303fabcf992bf2a11acd5ba644d289
redis-cli -p 7005 cluster replicate fe9d495d0c1d4164897d919478b3532ea3e4617b
redis-cli -p 7006 cluster replicate 0945ef9ecaeb9ab46e8622eb68d4457f94f9c58d
查看节点信息 redis-cli -p 7001 cluster nodes
4228b57d5a303fabcf992bf2a11acd5ba644d289 192.168.245.134:7001@17001 myself,master - 0 1641293323000 12 connected

8.编写脚本分配slots(槽点)
cd /app/cmw/redis/cluster/scripts
vi addslots.sh
start=$1
end=$2
port=$3
for slot in `seq ${start} ${end}`
do
redis-cli -p ${port} cluster addslots ${slot}
done
echo ${port} slots ${start} - ${end} done
执行脚本
sh addslots.sh 0 5460 7001
sh addslots.sh 5461 10922 7002
sh addslots.sh 10923 16383 7003
9.验证槽点分配情况
redis-cli -p 7001 cluster slots
#显示如下,证明成功
