1、配置中心

  使用nacos来做配置中心

1.1 nacos的命名空间

可以使用命名空间，来对远程配置文件进行分组。这样可以更好的分类。

点击下面切换到刚创建的命名空间

 把一些公共配置抽离出来，比如mysql的连接

 

 1.2 添加配置

新建bootstrap.properties

#服务名
spring.application.name=springcloud-good
#制定nacos服务地址
spring.cloud.nacos.config.server-addr=localhost:81
#指定主文件名
spring.cloud.nacos.config.name=?
#指定文件类型
spring.cloud.nacos.config.file-extension=properties
#指定命名空间
spring.cloud.nacos.config.namespace=41a97032-c17b-4c51-b159-6659a3f1e362
#指定文件id
spring.cloud.nacos.config.extension-configs[0].data-id=db.properties
#指定分组
spring.cloud.nacos.config.extension-configs[0].group=DEFAULT_GROUP
#是否每次修改刷新
spring.cloud.nacos.config.extension-configs[0].refresh=true

然后开启nacos服务，并打开项目就可以看到已经加载远程配置文件了

2、 链路追踪

2.1、zipkin + sleuth链路追踪

2.1.1、添加依赖

zipkin集成了 sleuth不需要再导他的包了 微服务中加到父工程中，其他子模块都可以共享

    
        org.springframework.cloud
        spring-cloud-starter-zipkin
    

2.1.2、修改application.properties

每个模块添加该配置

#zipkin服务地址

spring.zipkin.base-url=http://127.0.0.1:9411/

#不被nacos服务注册

spring.zipkin.discovery-client-enabled=false

#保存日志文件的百分比 1.0即100%

spring.sleuth.sampler.probability=1.0

2.1.3、日志持久化

下载zipkin-server

Central Repository: io/zipkin/zipkin-server

注意:2.12.9版本的跟mysql8.0可能不太兼容

持久化到MySQL

执行zipkin-server

java -jar zipkin-server-2.21.0-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=127.0.0.1 --MYSQL_TCP_PORT=3306 --MYSQL_DB=zipkin --MYSQL_USER=root --MYSQL_PASS=123456

 2.2、skywalking链路追踪

2.2.1 下载skywalking

https://download.csdn.net/download/qq_41720578/86438365

2.2.2 修改储存方式

config目录下的application.yml

storage:
  selector: ${SW_STORAGE:mysql}

#修改mysql链接地址 和密码账号

mysql:
    properties:
      jdbcUrl: ${SW_JDBC_URL:"jdbc:mysql://localhost:3306/swtest?serverTimezone=Asia/Shanghai"}
      dataSource.user: ${SW_DATA_SOURCE_USER:root}
      dataSource.password: ${SW_DATA_SOURCE_PASSWORD:123}
      dataSource.cachePrepStmts: ${SW_DATA_SOURCE_CACHE_PREP_STMTS:true}
      dataSource.prepStmtCacheSize: ${SW_DATA_SOURCE_PREP_STMT_CACHE_SQL_SIZE:250}
      dataSource.prepStmtCacheSqlLimit: ${SW_DATA_SOURCE_PREP_STMT_CACHE_SQL_LIMIT:2048}
      dataSource.useServerPrepStmts: ${SW_DATA_SOURCE_USE_SERVER_PREP_STMTS:true}
    metadataQueryMaxSize: ${SW_STORAGE_MYSQL_QUERY_MAX_SIZE:5000}
    maxSizeOfArrayColumn: ${SW_STORAGE_MAX_SIZE_OF_ARRAY_COLUMN:20}
    numOfSearchableValuesPerTag: ${SW_STORAGE_NUM_OF_SEARCHABLE_VALUES_PER_TAG:2}

进入bin目录运行脚本startuo.bat

然后再启动项目时，配置启动参数。

-Dskywalking.agent.service_name=springcloud-good#服务名
-Dskywalking.collector.backend_service=localhost:11800#日志端口号
