篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Redisarm64架构，docker的Redis出现Failed to test the kernel for a bug that could lead to data corruption相关的知识，希望对你有一定的参考价值。

一、问题说明

在运行docker的redis镜像，log打印

# Failed to test the kernel for a bug that could lead to data corruption during background save. Your system could be affected, please report this error.
# Redis will now exit to prevent data corruption. Note that it is possible to suppress this warning by setting the following config: ignore-warnings ARM64-COW-BUG

翻译：

#无法测试内核是否存在可能导致后台保存期间数据损坏的错误。您的系统可能受到影响，请报告此错误。

#Redis现在将退出以防止数据损坏。请注意，可以通过设置以下配置来抑制此警告：忽略警告ARM64-COW-BUG

二、解决方法

解决方式很简单，日志已经提醒需要在redis.config中添加配置 

 ignore-warnings ARM64-COW-BUG

但是，容器都没启动成功，根本没法获取容器中的redis.conf文件。

因此，需要先在宿主机上配置好redis.conf，再映射进容器中

我们需要在redis官网找到对应redis版本的配置文件，版本可以在dockerHub上查

Redis configuration | RedisOverview of redis.conf, the Redis configuration filehttps://redis.io/docs/manual/config/

1、查找redis镜像使用的版本

2、在官网找到对应版本，复制进创建的redis.conf 

 3、然后将配置文件最后一行#ignore-warnings ARM64-COW-BUG的注释#去掉， 保存即可

4、然后重新运行redis容器

# 映射配置文件所在地址：  -v /docker_home/redis_home/conf:/usr/local/etc/redis
# 映射redis数据保存地址： -v/docker_home/redis_home/data:/data
# 使用配置文件：redis-server /usr/local/etc/redis/redis.conf
# 设置默认将数据保存到磁盘时间60秒：--save 60 1
# 映射6379端口：-p 6379:6379

docker run -v /docker_home/redis_home/conf:/usr/local/etc/redis -v/docker_home/redis_home/data:/data -p 6379:6379 -d --name redis redis redis-server /usr/local/etc/redis/redis.conf --save 60 1

 顺利运行

云原生一篇打通微服务架构，nacos + gateway + Redis + MySQL + docker

目录

一、前期准备

本项目暂定项目名GooReeyProject，SpringBoot + Vue构建，具体项目内容未定。

基本架构nacos、gateway、Linux、Redis、rabbitMQ、MySQL、docker、Vue。

1、安装MySQL5.7

2、安装nacos

我安装的是window版的nacos和MySQL，安装nacos时需要注意，要讲配置文件中的集群版改为单机版，才能启动！

3、安装Redis

二、创建父工程

我觉得主要是pom文件

<?xml version="1.0" encoding="UTF-8"?>

                </includes>
            </resource>
        </resources>
    </build>
</project>

三、创建gateway子工程

1、pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>GooReeyProject</artifactId>
        <groupId>com.guor</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
 
    <artifactId>02gateway</artifactId>
 
    <dependencies>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>
        <dependency>

            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
    </dependencies>
 
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
                <exclusions>
                    <exclusion>
                        <groupId>org.springframework.cloud</groupId>
                        <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <build>
        <finalName>gateway-$system.version</finalName>
    </build>
</project>

2、配置文件

spring:
  application:
    name: gateway
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
      config:
        server-addr: 127.0.0.1:8848
        file-extension: yml
        ext-config:
          - data-id: datasource-share-config.yml
            group: SHARE_GROUP
            refresh: true
          - data-id: log-share-config.yml
            group: SHARE_GROUP
            refresh: true

（1）gateway.yml

server:
  port: 8080
      
spring:
  application:
    name: gateway
    version: 1.0.0
  cloud:
    gateway:                      
      discovery:
        locator:
          enabled: true
          lowerCaseServiceId: true
          filters: 
            - StripPrefix=1     
      routes:
        - id: management
          uri: lb:management   # 服务端 service_id
          predicates:
            - Path=/management/**
          filters: 
            - name: Hystrix 
              args: 
                name: fallbackcmd
                fallbackUri: forward:/defaultFallback
        - id: demo
          uri: lb://demo
          predicates:
            - Path=/demo/**
            
hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: SEMAPHORE
          thread:
            timeoutInMilliseconds: 1500

（2）datasource-share-config.yml

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/blue?serverTimezone=UTC
    driverClassName: com.mysql.cj.jdbc.Driver
    username: root
    password: root
mybatis:
  typeAliasesPackage: com.guor.*.bean.**
  mapperLocations: classpath*:**/com/guor/**/dao/mapping/*Mapper.xml
  configuration:
    map-underscore-to-camel-case: true

（3）log-share-config.yml

logging: 
  path: logs
  level:
    root: info
    com.alibaba.nacos.client.naming: warn 
  file: 
    max-size: 20MB
    max-history: 30
  pattern: 
    file: "%d$LOG_DATEFORMAT_PATTERN:yyyy-MM-dd HH:mm:ss.SSS $LOG_LEVEL_PATTERN:%5p $PID:-  --- [%15.15t] %-40.40logger39 [%5.5line] : %m%n$LOG_EXCEPTION_CONVERSION_WORD:%wEx"
    console: "%d$LOG_DATEFORMAT_PATTERN:yyyy-MM-dd HH:mm:ss.SSS %clr($LOG_LEVEL_PATTERN:%5p) %clr($PID:- )magenta --- %clr([%15.15t])faint %clr(%-40.40logger39)cyan %clr([%5.5line])cyan : %m%n$LOG_EXCEPTION_CONVERSION_WORD:%wEx"

3、启动类

package com.guor;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.scheduling.annotation.EnableScheduling;
 
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@EnableDiscoveryClient
@EnableScheduling
@RefreshScope
public class GatewayApplication 
    public static void main(String[] args) 
        SpringApplication.run(GatewayApplication.class, args);
        System.out.println("hello world");

四、创建management管理模块

1、pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>GooReeyProject</artifactId>
        <groupId>com.guor</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
 
    <artifactId>03management</artifactId>
 
    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
        </dependency>
        <!--MySQL依赖 --&
