之前写过一套基于redis-4.0.6版本的测试集群部署

https://www.cnblogs.com/mrice/p/10730309.html

最近生产环境需要部署一套redis-5.0.5版本集群；

环境:

服务器：6台

操作系统:Red Hat Enterprise Linux Server release 7.4

redis:redis-5.0.5

ruby:ruby-2.0.0 (redis-3.3.5.gem)

一、基础安装

1、安装好ruby

2、安装redis-3.3.5.gem

gem install redis-3.3.5.gem

3、修改系统变量

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf
echo 511 > /proc/sys/net/core/somaxconn
sysctl -p

二、redis安装

1、安装redis

压缩安装包后

make && make install

2、配置redis

从安装文件中复制一份redis.conf,下面是配置文件内容,红色字体大家需要注意一下。

bind 10.20.1.56  //修改绑定地址
protected-mode yes
port 6379   //可修改自己规则端口,但集群状态下需要注意,集群使用端口会在此端口上增加10000，所以redis自身端口+10000不能超过65535。
tcp-backlog 511
timeout 0
tcp-keepalive 300
daemonize yes
supervised no
pidfile /mrice/redis-cluster/redis-6379/redis_6379.pid  //pid存放位置
loglevel notice
logfile "/mrice/redis-cluster/redis-6379/logs/redis_6379.log"
databases 16
always-show-logo yes
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
dir "/mrice/redis-cluster/redis-6379/data"  //数据存放目录
replica-serve-stale-data yes
replica-read-only yes
repl-diskless-sync no
repl-diskless-sync-delay 5
repl-disable-tcp-nodelay no
replica-priority 100
requirepass mrice   //增加认证
masterauth mrice   //主从复制时认证密码
lazyfree-lazy-eviction no
lazyfree-lazy-expire no
lazyfree-lazy-server-del no
replica-lazy-flush no
appendonly no
appendfilename "appendonly.aof"
appendfsync everysec
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
aof-load-truncated yes
aof-use-rdb-preamble yes
lua-time-limit 5000
cluster-enabled yes //开启集群功能
cluster-config-file /mrice/redis-cluster/redis-6379/logs/nodes.conf  //集群状态
slowlog-log-slower-than 10000
slowlog-max-len 128
latency-monitor-threshold 0
notify-keyspace-events ""
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-size -2
list-compress-depth 0
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
hll-sparse-max-bytes 3000
stream-node-max-bytes 4096
stream-node-max-entries 100
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit replica 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10
dynamic-hz yes
aof-rewrite-incremental-fsync yes
rdb-save-incremental-fsync yes

3、配置文件修改完后，启动redis服务

redis-server redis.conf

4、建立集群

这里注意的是以之前版本不同的是,通过redis-cli 来完成。

redis-cli --cluster create 10.20.1.51:6379 10.20.1.52:6379 10.20.1.53:6379 10.20.1.54:6379 10.20.1.55:6379 10.20.1.56:6379 --cluster-replicas 1 -a mrice

Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
