集群规划：
基于6台服务器进行安装
第一章: 所有节点下载安装redis
1、#所有节点操作
yum install -y gcc automake autoconf libtool make
mkdir /application/ -p
wget https://download.redis.io/releases/redis-7.0.7.tar.gz
tar -xf redis-7.0.7.tar.gz -C /usr/local/
cd /usr/local/
mv redis-7.0.7 redis
make
2、#创建工作目录环境
mkdir /application/redis/{conf,data,logs,tmp} -p
3、编写配置文件
cd /application/redis/conf/
4、将以下配置写入redis.conf文件
bind 0.0.0.0
port 6379
loglevel notice
logfile "/application/redis/logs/redis.log"
pidfile /application/redis/tmp/redis.pid
daemonize yes
tcp-backlog 600
timeout 0
tcp-keepalive 0
# 集群相关配置
# 是否以集群模式启动
cluster-enabled yes
# 集群节点回应最长时间，超过该时间被认为下线
cluster-node-timeout 15000
# 生成的集群节点配置文件名，文件名需要修改
cluster-config-file nodes.conf
# 持久化配置
dir /application/redis/data
appendonly yes
appendfilename "appendonly.aof"
appendfsync everysec
no-appendfsync-on-rewrite yes
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 1024mb
aof-load-truncated yes
aof-rewrite-incremental-fsync yes
save 900 1
save 300 10
save 60 10000
dbfilename dump.rdb
rdbcompression yes
stop-writes-on-bgsave-error yes
rdbchecksum yes
# 安全配置
requirepass 1qaz@WSX
# 慢查询配置
slowlog-log-slower-than 1000000
slowlog-max-len 50
#参数优化
maxclients 10000
maxmemory 2G
maxmemory-policy allkeys-lru
maxmemory-samples 5
lua-time-limit 5000第二章：所有节点使用systemctl管理启动redis
1、所有节点写入服务配置文件
cat /usr/lib/systemd/system/redis.service
[Unit]
Description=redis
After=network-online.target syslog.target
[Service]
Type=forking
User=root
Group=root
ExecStart=/usr/local/redis/src/redis-server /application/redis/conf/redis.conf
ExecReload=/bin/kill -s HUP
ExecStop=/bin/kill -s QUIT
PrivateTmp=true
LimitNOFILE = 65536
LimitNPROC = 65536
PermissionsStartOnly=true
Restart=on-failure
RestartPreventExitStatus=1
[Install]
WantedBy=multi-user.target
2、所有节点启动redis
systemctl daemon-reload
systemctl enable --now redis.service第三章：集群生成操作
