redis5 集群部署

1 服务器分配

服务器三台：192.168.0.36、192.168.0.37、192.168.0.38

2 上传安装包至第一台服务器/u01目录,并安装

cd /u01
tar xzf redis-5.0.6.tar.gz
cd redis-5.0.6
make
mkdir -p conf/6379
mkdir -p conf/6380

下载地址：https://download.redis.io/releases/

#若使用更高版本，安装后没有启动脚步，更换命令如下
make && make PREFIX=/redis/redis-7.4.1/ install

2 配置

2.1 配置6379节点

vim conf/6379/redis.conf

输入文件内容

#bind 127.0.0.1  注释掉
#需要不同服务器的节点连通，这个就要设置为 no
protected-mode no 
#设置后台运行redis
daemonize yes
#no，redis启动时会从rdb文件恢复数据,yes不会。
appendonly yes
port 6379
pidfile /u01/redis-5.0.6/run/redis_6379.pid
appendfilename "appendonly_6379.aof"
logfile "/u01/redis-5.0.6/log/redis_6379.log"
#不要密码就注释
requirepass password
#集群配置
cluster-enabled yes
cluster-node-timeout 5000
cluster-config-file nodes-6379.conf
#持久化配置
#dbfilename：持久化数据存储在本地的文件
dbfilename dump_6379.rdb
#dir：持久化数据存储在本地的路径，如果是./在/redis/redis-3.0.6/src下启动的redis-cli，则数据会存储在当前src目录下
dir /u01/redis-5.0.6/dbfile
#save时间，以下分别表示更改了1个key时间隔900s进行持久化存储；更改了10个key300s进行存储；更改10000个key60s进行存储。
save 900 1
save 300 10
save 60 10000

2.2 配置6380节点

vim conf/6380/redis.conf

输入文件内容

#bind 127.0.0.1  注释掉
#需要不同服务器的节点连通，这个就要设置为 no
protected-mode no 
#设置后台运行redis
daemonize yes
appendonly yes
port 6380
pidfile /u01/redis-5.0.6/run/redis_6380.pid
appendfilename "appendonly_6380.aof"
logfile "/u01/redis-5.0.6/log/redis_6380.log"
#不要密码就注释
requirepass password
#集群配置
cluster-enabled yes
cluster-node-timeout 5000
cluster-config-file nodes-6380.conf
#持久化配置
#dbfilename：持久化数据存储在本地的文件
dbfilename dump_6380.rdb
#dir：持久化数据存储在本地的路径，如果是./在/redis/redis-3.0.6/src下启动的redis-cli，则数据会存储在当前src目录下
dir /u01/redis-5.0.6/dbfile
#save时间，以下分别表示更改了1个key时间隔900s进行持久化存储；更改了10个key300s进行存储；更改10000个key60s进行存储。
save 900 1
save 300 10
save 60 10000

配置参考https://blog.youkuaiyun.com/ljl890705/article/details/51039015/

2.3 创建log、run目录

mkdir -p  /u01/redis-5.0.6/log
mkdir -p  /u01/redis-5.0.6/run
mkdir -p  /u01/redis-5.0.6/dbfile

3 将按照设置好的redis复制到另外两台服务器

cd /u01
scp -r redis-5.0.6 root@192.168.0.37:/u01
scp -r redis-5.0.6 root@192.168.0.38:/u01

4 在三台服务器上分别启动redis

/u01/redis-5.0.6/src/redis-server /u01/redis-5.0.6/conf/6379/redis.conf
/u01/redis-5.0.6/src/redis-server /u01/redis-5.0.6/conf/6380/redis.conf

5 执行创建集群

如果没有设置密码 删除 -a password

/u01/redis-5.0.6/src/redis-cli --cluster create --cluster-replicas 1 -a password 192.168.0.36:6379 192.168.0.37:6379 192.168.0.38:6379 192.168.0.36:6380 192.168.0.37:6380 192.168.0.38:6380

执行结果：
