创建集群
yum -y install ruby ruby-devel rubygems rpm-build
gem install redis
(如果不能执行，则wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem 然后执行命令gem install -l ./redis-3.2.1.gem)
./redis-trib.rb create --replicas 1 30.12.53.134:7000 30.12.53.134:7001 30.12.53.134:7002 30.12.53.140:7003 30.12.53.140:7004 30.12.53.140:7005
进入redis
redis-cli -c -p 7000
cluster nodes
单机启动
cd bin
./redis-server /data/software/redis-4.0.2/redis.conf

1快捷键 ctrl shift f9 热部署 idea debug模式
springcloud 踩坑日志
2通过zuul 网关上传文件 会出现中文乱码，需要在uri网关前面加上zuul
3 feignclient调用 降级 异常日志处理
@Component
static class ScheduleServiceHystrixClientFallbackFactory implements FallbackFactory
@Override
public IScheduleServiceFeignClient create(Throwable cause) {
//log不要写在这里 否则启动的时候会报异常信息
return new IScheduleServiceFeignClient() {
@Override
public ServiceResultDTO saveSchedule(OpenScheduleDto openScheduleDto) {
logger.error("IScheduleServiceFeignClient 调用SERVICE-BASE服务失败{}", cause); //不要写在匿名内部内之前， 否则启动的时候会报异常信息，但是不影响启动
return ServiceResultDTO.build("ex", "调用服务进行待办推送服务出错!");
}
}
@EnableFeignClients(basePackages = {"com.qiye.ext.service","com.qiye.base.service"}) 这时候只扫描配置了包下@feigin注解上相关包的接口或类

1 安装 Gcc环境 yum install -y gcc g++ gcc-c++ make
解压redis路径 /data/software/redis-4.0.10/
集群配置路径 /usr/local/myRedis/redis-cluster

cp /data/software/redis-4.0.10/src/redis-server /usr/local/myRedis/redis-cluster/7000
vim redis.conf 每个redis下面的redis.conf的配置（以下是我的）：
port 7001 //端口7001,7002,7003
bind 本机ip //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访问对应的端口，无法创建集群，我直接注释掉了
daemonize yes //redis后台运行
pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7001,7002
cluster-enabled yes //开启集群 把注释#去掉
cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7001,7002,7003
cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置
appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志

经测试 spring定时器@Scheduled(cron=） 在集群模式下，运行代码内容时间起点是不一致的，有微小差距，微妙级别，导致定时器重复执行，后面
又趋于正常（可能是cpu是单核的吧，测试是在同一台机器
开某个服务部署2个节点），所以可能存在定时器重复执行，建议在定时器里处理业务代码的时候，休眠0.5毫秒或1秒，如果业务逻辑处理很快
再加上服务器存在的时间差，导致定时器重复执行。
