tar -zxvf redis-4.0.2.tar.gz

cd redis-4.0.2

make && make install

vi redis.conf

修改 daemonize yes

cd /usr/local/

mkdir redis_cluster

mkdir 7000 7001 7002

cp /data/software/redis-4.0.2/redis.conf ./redis_cluster/7000/

//拷贝到7001目录

cp /data/software/redis-4.0.2/redis.conf ./redis_cluster/7001/

//拷贝到7002目录

cp /data/software/redis-4.0.2/redis.conf ./redis_cluster/7002/

分别修改3个配置文件

daemonize yes //redis后台运行

pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7002,7003

port 7000 //端口7000,7002,7003

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 7000,7001,7002

cluster-node-timeout 5000 //请求超时设置5秒够了

appendonly yes

启动6个节点

cd /usr/local

redis-server redis_cluster/7000/redis.conf

redis-server redis_cluster/7001/redis.conf

redis-server redis_cluster/7002/redis.conf

redis-server redis_cluster/7003/redis.conf

redis-server redis_cluster/7004/redis.conf

redis-server redis_cluster/7005/redis.conf

cd /data/software/redis-4.0.10/src/

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

./redis-cli

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<IScheduleServiceFeignClient> {

@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

-------------------reids集群搭建

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/redis.conf /usr/local/myRedis/redis-cluster/7000

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

可以查看 https://blog.csdn.net/xiaoguaihu12/article/details/56845473

7000目录下到其兄弟目录下（7001-7005）

cp * /usr/local/myRedis/redis-cluster/7001

启动6个redis

//分配主从

./redis-trib.rb create --replicas 1 30.23.13.36:7000 30.23.13.36:7001 30.23.13.36:7002 30.23.13.36:7003 30.23.13.36:7004 30.23.13.36:7005

//连接集群某一个节点即可

redis-cli -c -h 30.23.13.36 -p 7003

redis-cli -c -h 30.23.8.8 -p 7000

//启动

cd /usr/local/myRedis/redis-cluster/7000

./redis-server ./redis.conf

cd /usr/local/myRedis/redis-cluster/7001

./redis-server ./redis.conf

cd /usr/local/myRedis/redis-cluster/7002

./redis-server ./redis.conf

cd /usr/local/myRedis/redis-cluster/7003

./redis-server ./redis.conf

cd /usr/local/myRedis/redis-cluster/7004

./redis-server ./redis.conf

cd /usr/local/myRedis/redis-cluster/7005

./redis-server ./redis.conf

//关闭或kill -9 进程Id 通过pkill -9 redis杀死reids 进程之后，重新启动各个节点，集群自动创建成功（杀死之前的集群状态）

注意：前提是不要清空nodes.conf文件

//gc

cd /usr/local/myRedis/redis-cluster/7000
