這篇文章將為大家詳細(xì)講解有關(guān)redis集群Cluster模式如何部署,小編覺(jué)得挺實(shí)用的,因此分享給大家做個(gè)參考,希望大家閱讀完這篇文章后可以有所收獲。
一、Redis 集群模式搭建
redis集群部署分為三種:主從、哨兵(Sentinel)、集群(Cluster)。
前幾天由于新應(yīng)用上線,需要部署一套redis集群,現(xiàn)形成文檔,將部署過(guò)程進(jìn)行記錄。
環(huán)境介紹
ip | 軟件包 | 系統(tǒng)版本 |
10.1.112.248 | redis-4.0.11.tar.gz | CentOS Linux release 7.6.1810 (Core) |
10.1.112.249 | redis-4.0.11.tar.gz | CentOS Linux release 7.6.1810 (Core) |
1、目錄結(jié)構(gòu)
[root@localhost local]# pwd /usr/local [root@localhost local]# tree redis-cluster/ redis-cluster/ ├── redis-4.0.11-node1 │ ├── data │ └── logs ├── redis-4.0.11-node2 │ ├── data │ └── logs └── redis-4.0.11-node3 ├── data └── logs 9 directories, 0 files
2、下載解壓redis-4.0.11
mkdir /usr/local/software cd /usr/local/software && wget http://download.redis.io/releases/redis-4.0.11.tar.gz tar xf redis-4.0.11.tar.gz
3、安裝(兩臺(tái)服務(wù)器均安裝)
[root@localhost software]# pwd /usr/local/software [root@localhost software]# tar xf redis-4.0.11.tar.gz [root@localhost software]# cd redis-4.0.1 [root@localhost redis-4.0.11]# make install 出現(xiàn)如下截圖即可
4、準(zhǔn)備配置文件
[root@localhost redis-4.0.11]# cp src/redis-trib.rb /usr/local/bin/ [root@localhost redis-4.0.11]# cp redis.conf /usr/local/redis-cluster/redis-4.0.11-node1/ [root@localhost redis-4.0.11]# cp redis.conf /usr/local/redis-cluster/redis-4.0.11-node2/ [root@localhost redis-4.0.11]# cp redis.conf /usr/local/redis-cluster/redis-4.0.11-node3/ [root@localhost redis-4.0.11]# cp src/{redis-cli,redis-server} /usr/local/redis-cluster/redis-4.0.11-node1/ [root@localhost redis-4.0.11]# cp src/{redis-cli,redis-server} /usr/local/redis-cluster/redis-4.0.11-node2/ [root@localhost redis-4.0.11]# cp src/{redis-cli,redis-server} /usr/local/redis-cluster/redis-4.0.11-node3/ [root@localhost redis-4.0.11-node1]# grep -Ev "^#|^$" redis.conf bind 10.1.112.248 #領(lǐng)一臺(tái)服務(wù)器配置為10.1.112.249 protected-mode yes port 7000 #其他節(jié)點(diǎn)分別配置為7001/7002 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize yes supervised no pidfile /usr/local/redis-cluster/redis-4.0.11-node1/redis_7000.pid #其他節(jié)點(diǎn)配置為redis-4.0.11-node2/redis_7001.pid、redis-4.0.11-node3/redis_7002.pid loglevel notice logfile "/usr/local/redis-cluster/redis-4.0.11-node1/logs/redis_7000.log" #同上 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 /usr/local/redis-cluster/redis-4.0.11-node1/data #redis-4.0.11-node3/data、redis-4.0.11-node3/data slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 requirepass xxx lazyfree-lazy-eviction no lazyfree-lazy-expire no lazyfree-lazy-server-del no slave-lazy-flush no appendonly yes 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 no lua-time-limit 5000 cluster-enabled yes cluster-config-file nodes-7000.conf cluster-node-timeout 15000 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 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
5、分別啟動(dòng)3個(gè)節(jié)點(diǎn)(另一臺(tái)服務(wù)器同樣啟動(dòng))
cd /usr/local/redis-cluster/redis-4.0.11-node1 ./redis.server redis.conf cd /usr/local/redis-cluster/redis-4.0.11-node2 ./redis.server redis.conf cd /usr/local/redis-cluster/redis-4.0.11-node3 ./redis.server redis.conf 查看進(jìn)程 [root@localhost redis-4.0.11-node1]# ps -ef |grep redis root 6015 5673 0 17:52 pts/1 00:00:00 grep --color=auto redis weblogic 28246 1 0 Oct21 ? 00:01:14 ./redis-server 10.1.112.248:7000 [cluster] weblogic 28284 1 0 Oct21 ? 00:01:14 ./redis-server 10.1.112.248:7001 [cluster] weblogic 28301 1 0 Oct21 ? 00:02:25 ./redis-server 10.1.112.248:7002 [cluster] [root@localhost redis-4.0.11-node1]# ps -ef |grep redis root 6015 5673 0 17:52 pts/1 00:00:00 grep --color=auto redis weblogic 28246 1 0 Oct21 ? 00:01:14 ./redis-server 10.1.112.249:7000 [cluster] weblogic 28284 1 0 Oct21 ? 00:01:14 ./redis-server 10.1.112.249:7001 [cluster] weblogic 28301 1 0 Oct21 ? 00:02:25 ./redis-server 10.1.112.249:7002 [cluster]
6、使用 redis-trib.rb創(chuàng)建集群
[root@localhost redis-4.0.11-node1]# yum -y install ruby ruby-devel rubygems rpm-build [root@localhost redis-4.0.11-node1]# gem install redis Fetching: redis-4.1.3.gem (100%) ERROR: Error installing redis: redis requires Ruby version >= 2.3.0. 提示ruby版本過(guò)低。 升級(jí)ruby版本 [root@localhost redis-4.0.11-node1]# curl -L get.rvm.io | bash -s stable 按提示導(dǎo)入秘鑰,再次執(zhí)行"curl -L get.rvm.io | bash -s stable" [root@localhost redis-4.0.11-node1]# source /usr/local/rvm/scripts/rvm 查看可用的ruby版本并安裝 [root@localhost redis-4.0.11-node1]# rvm list known [root@localhost redis-4.0.11-node1]# rvm install 2.3.0 #這一步用時(shí)較長(zhǎng),耐心等待安裝完成。
7、安裝gem redis接口
rvm use 2.3.0 ruby --version gem install redis
8、安裝rubygems
yum install -y rubygems
至此,Ruby和運(yùn)行redis-trib.rb需要的環(huán)境安裝完成了,接下來(lái)使用redis-trib.rb創(chuàng)建集群
9、創(chuàng)建集群
redis-trib.rb create --replicas 1 10.1.112.248:7000 10.1.112.248:7001 10.1.112.248:7002 10.1.112.249:7000 10.1.112.249:7001 10.1.112.249:7002
10、查看集群狀態(tài)
[weblogic@geb-redis1 ~]$ redis-trib.rb check 10.1.112.248:7000 >>> Performing Cluster Check (using node 10.1.112.248:7000) M: 61d94b047e12679886991c7c6d225b471374a018 10.1.112.248:7000 slots:0-5460 (5461 slots) master 1 additional replica(s) S: a582b9d7784d2f1b2e6a20d5352a19062dc29d4a 10.1.112.248:7002 slots: (0 slots) slave replicates 0addc56bce940a659aa2ac4aa6d51677c1f2c523 M: 0addc56bce940a659aa2ac4aa6d51677c1f2c523 10.1.112.249:7000 slots:5461-10922 (5462 slots) master 1 additional replica(s) S: 087de17dafa03c361d87f7a4c4a5b2d7ce0555fc 10.1.112.249:7001 slots: (0 slots) slave replicates fd9f572038a7504e088dde150b89beb2bac39e3c M: fd9f572038a7504e088dde150b89beb2bac39e3c 10.1.112.248:7001 slots:10923-16383 (5461 slots) master 1 additional replica(s) S: 407d6ea2eb3725e142d2e5ae4e1eef4eee1a48ca 10.1.112.249:7002 slots: (0 slots) slave replicates 61d94b047e12679886991c7c6d225b471374a018 [OK] All nodes agree about slots configuration. >>> Check for open slots... >>> Check slots coverage... [OK] All 16384 slots covered.
11、整體目錄結(jié)構(gòu)
[root@geb-redis1 redis-cluster]# tree . ├── redis-4.0.11-node1 │ ├── data │ │ ├── appendonly.aof │ │ └── nodes-7000.conf │ ├── logs │ │ └── redis_7000.log │ ├── redis_7000.pid │ ├── redis-cli │ ├── redis.conf │ └── redis-server ├── redis-4.0.11-node2 │ ├── data │ │ ├── appendonly.aof │ │ └── nodes-7001.conf │ ├── logs │ │ └── redis_7001.log │ ├── redis_7001.pid │ ├── redis-cli │ ├── redis.conf │ └── redis-server └── redis-4.0.11-node3 ├── data │ ├── appendonly.aof │ └── nodes-7002.conf ├── logs │ └── redis_7002.log ├── redis_7002.pid ├── redis-cli ├── redis.conf └── redis-server 9 directories, 21 files [root@geb-redis2 redis-cluster]# tree . ├── redis-4.0.11-node1 │ ├── data │ │ ├── appendonly.aof │ │ └── nodes-7000.conf │ ├── logs │ │ └── redis_7000.log │ ├── redis_7000.pid │ ├── redis-cli │ ├── redis.conf │ └── redis-server ├── redis-4.0.11-node2 │ ├── data │ │ ├── appendonly.aof │ │ └── nodes-7001.conf │ ├── logs │ │ └── redis_7001.log │ ├── redis_7001.pid │ ├── redis-cli │ ├── redis.conf │ └── redis-server └── redis-4.0.11-node3 ├── data │ ├── appendonly.aof │ └── nodes-7002.conf ├── logs │ └── redis_7002.log ├── redis_7002.pid ├── redis-cli ├── redis.conf └── redis-server 9 directories, 21 files
12、部署過(guò)程中需要調(diào)整的系統(tǒng)參數(shù)
# echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf # echo "net.core.somaxconn = 2048" >> /etc/sysctl.conf # cat /etc/rc.local if test -f /sys/kernel/mm/transparent_hugepage/enabled; then echo never > /sys/kernel/mm/transparent_hugepage/enabled fi if test -f /sys/kernel/mm/transparent_hugepage/defrag; then echo never > /sys/kernel/mm/transparent_hugepage/defrag fi
