redis linux-集群配置流程

来源：互联网发布：js 写cookie 编辑：程序博客网时间：2024/05/18 00:56

一。配置修改

1.在/usr/local/redis-3.2.7下新建目录

cluster/6379
....
cluster/6384
由于redis集群需要3个master所以最少要6个服务所以需要6个文件夹
2.在每个目录下拷贝redis.conf

3.在redis linux-单个配置流程配置基础上修改/usr/local/redis-3.2.7/cluster/6379/redis.conf

logfile "/usr/local/redis-3.2.7/cluster/6379/redis-6379.log"

dir "/usr/local/redis-3.2.7/cluster/6379/"

721行：cluster-enabled yes
729行: cluster-config-file nodes-6379.conf
735行：cluster-node-timeout 5000

二。redis集群需要使用ruby，安装ruby

yum -y install zlib ruby rubygems

安装ruby的redis
gem install redis

升级ruby安装的软件
gem update --system
gem update

查看ruby安装的软件的结合
gem list

三。启动所有redis服务

./redis-server /usr/local/redis-3.2.7/cluster/6379/redis.conf

......

./redis-server /usr/local/redis-3.2.7/cluster/6384/redis.conf

四.修改集群密码

打开：/usr/lib64/ruby/gems/1.8/gems/redis-3.3.3/lib/redis/client.rb

修改password为设置的密码

四。执行./redis-trib.rb create --replicas 1 ip:6379 ...... ip:6384

如果成功会显示如下：

五：错误处理

1.Node XXX:6380 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

处理方法:登录到对应server ./redis-cli -h 120.77.61.47 -p 6380

清除数据：flashdb

2.大部分启动问题可以删除/usr/local/redis-3.2.7/cluster/6379中除去redis.conf其他所有文件再启动

六。spring-data-redis配置

redis-cluster.properties

#JedisPoolConfig的参数
#最大连接数
redis.pool.maxTotal=30
#最大空闲时间
redis.pool.maxIdle=10
#每次最大连接数
redis.pool.numTestsPerEvictionRun=1024
#释放扫描的扫描间隔
redis.pool.timeBetweenEvictionRunsMillis=30000
#连接的最小空闲时间
redis.pool.minEvictableIdleTimeMillis=1800000
#连接控歘按时间多久后释放，当空闲时间>该值且空闲连接>最大空闲连接数时直接释放
redis.pool.softMinEvictableIdleTimeMillis=10000
#获得链接时的最大等待毫秒数，小于0：阻塞不确定时间，默认-1
redis.pool.maxWaitMillis=1500
#在获得链接的时候检查有效性，默认false
redis.pool.testOnBorrow=true
#在空闲时检查有效性，默认false
redis.pool.testWhileIdle=true
#连接耗尽时是否阻塞，false报异常，true阻塞超时,默认true
redis.pool.blockWhenExhausted=false
#RedisClusterConfiguration配置
redis.maxRedirects=5
#密码
redis.password=mju76yhN
#主机和端口号
redis.host1=120.77.61.XX
redis.port1=6379
redis.host2=120.77.61.XX
redis.port2=6380
redis.host3=120.77.61.XX
redis.port3=6381
redis.host4=120.77.61.XX
redis.port4=6382
redis.host5=120.77.61.XX
redis.port5=6383
redis.host6=120.77.61.XX
redis.port6=6384
