Redis7.XCentos集群搭建

安装高版本Redis需要先安装Python3.x

下载

https://download.redis.io/redis-stable.tar.gz

部署

上传解压

tar -zxvf  redis-stable.tar.gz

编译安装

cd redis-stable
# 如果make出现异常，可以尝试make MALLOC=libc
make 
# 将redis安装到/usr/local/redis-stable目录下
make PREFIX=/usr/local/redis-stable install

创建6个节点的目录

# 创建日志目录
mkdir -p /usr/local/redis-cluster/{6379,6380,6381,6382,6383,6384}/log
# 创建配置文件目录
mkdir -p /usr/local/redis-cluster/{6379,6380,6381,6382,6383,6384}/config

写入配置文件(写入配置的时候请务必去掉注释)

# 6379节点配置文件
cat << EOF > /usr/local/redis-cluster/6379/config/redis.conf
protected-mode no
bind 0.0.0.0
port 6379 # 服务监听端口
daemonize yes # 后台启动
pidfile /usr/local/redis-cluster/6379/redis_6379.pid
masterauth test-cluster # 启动 redis 密码验证，主要是针对 master 对应的 slave 节点设置的，在 slave 节点数据同步的时候用到
requirepass test-cluster # redis密码，#启动 redis 密码验证，一定要 requirepass 和 masterauth 同时设置。对登录权限做限制，redis每个节点的requirepass可以是独立、不同的，但建议和 masterauth 设置成一样
appendonly yes # 开启持久化
dir /usr/local/redis-cluster/6379/ # AOF文件存放目录
appendfilename "appendonly.aof" #AOF文件名称（默认）
cluster-enabled yes # 启用集群
cluster-config-file "nodes.conf" # 关联集群的配置文件
cluster-node-timeout 5000 # 集群超时时间
cluster-require-full-coverage no # 只要有结点宕机导致 16384 个槽没全被覆盖，整个集群就全部停止服务，所以一定要改为 no
EOF

# 6380节点配置文件
cat << EOF > /usr/local/redis-cluster/6380/config/redis.conf
protected-mode no
bind 0.0.0.0
port 6380
daemonize yes
pidfile /usr/local/redis-cluster/6380/redis_6380.pid
masterauth test-cluster
requirepass test-cluster 
appendonly yes
dir /usr/local/redis-cluster/6380/
appendfilename "appendonly.aof" 
cluster-enabled yes
cluster-config-file "nodes.conf"
cluster-node-timeout 5000
cluster-require-full-coverage no
EOF

# 6381,6382,6383,6384配置文件参考上面的

分别启动redis

redis-server /usr/local/redis-cluster/6379/config/redis.conf
redis-server /usr/local/redis-cluster/6380/config/redis.conf
redis-server /usr/local/redis-cluster/6381/config/redis.conf
redis-server /usr/local/redis-cluster/6382/config/redis.conf
redis-server /usr/local/redis-cluster/6383/config/redis.conf
redis-server /usr/local/redis-cluster/6387/config/redis.conf

创建集群

redis-cli -a "test-cluster" --cluster create 192.168.137.10:6379 192.168.137.10:6380 192.168.137.10:6381 192.168.137.10:6382 192.168.137.10:6383 192.168.137.10:6384 --cluster-replicas 1

验证集群

redis-cli -h 192.168.137.10 -c -p 6380 -a "test-cluster"

集群查看相关命令

1.集群状态
redis-cli -h ip -p 6401 -a password cluster info
2.集群节点信息
redis-cli -h ip -p 6401 -a password cluster nodes
3.节点内存、cpu、key数量等信息（每个节点都需查看）
redis-cli -h ip -p 6401 -a password info
