centos7部署redis_3.2.9 cluster部署（三主三从

1，虚拟机环境

应用的Linux环境曾经版本：

Centos 7 64位零碎

主机ip ：

192.168.56.180

192.168.56.181

192.168.56.182

每台服务器是1主1从，试验3台服务器课成为3主3从。

Redis装置的我的项目目录，日志，配置文件等都寄存在/ root / svr /目录下。

2，下载相干的安装包以及解压

首先在192.168.56.180机器操作：

cd /data/work/wget http://download.redis.io/releases/redis-3.2.9.tar.gztar -zxvf redis-3.2.9.tar.gz

3，装置

在/data/work/redis-3.2.9/目录下执行：

make && make install PREFIX = / data / work / redis-3.2.9

4，配置信息

创立性能配置，日志日志，数据所在的文件夹：

cd /data/work/redis-3.2.9/`mkdir cluster-conf`mkdir -pv /data/work/redis-3.2.9/logs
 创立可用端口文件夹：
cd cluster-confmkdir 7777mkdir 8888
 配置复制文件到/数据/工作/redis-3.2.9/cluster-conf/7777目录下：
cp /data/work/redis-3.2.9/redis.conf  /data/work/redis-3.2.9/cluster-conf/7777
  • 批改7777目录下redis.conf（主）配置文件：
bind 192.168.56.181 127.0.0.1protected-mode yesmasterauth "xxxxx"requirepass "xxxxx"port 8888tcp-backlog 511timeout 0tcp-keepalive 300daemonize yessupervised nopidfile /data/work/redis-3.2.9/cluster-conf/8888/redis_8888.pidloglevel noticelogfile "/data/work/redis-3.2.9/logs/redis_8888.log"databases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbdir ./slave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100maxclients 100000appendonly noappendfilename "appendonly.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000cluster-enabled yescluster-config-file /data/work/redis-3.2.9/cluster-conf/8888/nodes-8888.confslowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes
  • 群集配置文件/data/work/redis-3.2.9/cluster-conf/8888/redis.conf (从)
bind 192.168.56.181 127.0.0.1protected-mode yesmasterauth "xxxxx"requirepass "xxxxx"port 8888tcp-backlog 511timeout 0tcp-keepalive 300daemonize yessupervised nopidfile /data/work/redis-3.2.9/cluster-conf/8888/redis_8888.pidloglevel noticelogfile "/data/work/redis-3.2.9/logs/redis_8888.log"databases 16save 900 1save 300 10save 60 10000stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbdir ./slave-serve-stale-data yesslave-read-only yesrepl-diskless-sync norepl-diskless-sync-delay 5repl-disable-tcp-nodelay noslave-priority 100maxclients 100000appendonly yesappendfilename "appendonly.aof"appendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbaof-load-truncated yeslua-time-limit 5000cluster-enabled yescluster-config-file /data/work/redis-3.2.9/cluster-conf/8888/nodes-8888.confslowlog-log-slower-than 10000slowlog-max-len 128latency-monitor-threshold 0notify-keyspace-events ""hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-size -2list-compress-depth 0set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64hll-sparse-max-bytes 3000activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-rewrite-incremental-fsync yes

5，应用scp复制装置和配置好的redis复制到其余服务器上

曾经在192.168.56.180机器配置好，复制到181和182机器

在两台新机器上创立文件夹

scp -r /data/work/redis-3.2.9 [root@192.168.56.181](mailto:root@192.168.56.181):/data/work/`#输出181机器明码即可传输数据。`scp -r /data/work/redis-3.2.9 [root@192.168.56.182](mailto:root@192.168.56.182):/data/work/``#输出182机器明码即可传输数据。`

6，启动3台机器的redis

3台机器执行启动形式：

/data/work/redis-3.2.9/bin/redis-server /root/svr/redis-3.2.9/cluster-conf/7777/redis.conf &/data/work/redis-3.2.9/bin/redis-server /root/svr/redis-3.2.9/cluster-conf/8888/redis.conf &

 查看状态是否：

ps -ef|grep redis

7，装置ruby2.4.0

gpg2 --recv键409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB`yum -y update nss`curl -sSL [https://get.rvm.io](https://get.rvm.io/) | bash -s稳固源/etc/profile.d/rvm.shrvm装置2.4.0rvm应用2.4.0gem install redisyum install rubygems

8，发明实力

/data/work/redis-3.2.9/src/redis-trib.rb create --replicas 1 192.168.56.180:7777 192.168.56.180:8888 192.168.56.181:7777 192.168.56.181:8888 192.168.56.182:7777 192.168.56.182:8888

无奈创立，提醒错误信息：

>>> Creating cluster[ERR] Sorry, can't connect to node 192.168.56.180:7777
批改配置文件redis.conf的权限设置平安明码（明码自定义设置）

  • 设置明码之后如果须要应用redis-trib.rb的各种命令
如：./redis-trib.rb check 127.0.0.1:7000，则会报错ERR] Sorry, can’t connect to node 127.0.0.1:7000解决办法：vim /usr/local/rvm/gems/ruby-2.3.3/gems/redis-4.0.0/lib/redis/client.rb，而后批改passordfind / -name client.rbvim /usr/local/rvm/gems/ruby-2.4.0/gems/redis-4.2.5/lib/redis/client.rb1 # frozen_string_literal: true..18 connect_timeout: nil,19 timeout: 5.0,20 password: "xxxxx", #######批改这里的明码（每台机器做同样的操作）**留神：client.rb门路能够通过find命令查找：find / -name 'client.rb'**带明码拜访集群/data/work/redis-3.2.9/bin/redis-cli -c -p 8888 -a xxxxx >>> Performing Cluster Check (using node 127.0.0.1:7777)M: d8xxxefxxxxxxxxxxxxxxxxxx2 127.0.0.1:7777slots: (0 slots) master0 additional replica(s)[OK] All nodes agree about slots configuration.
