Docker部署Seata与Nacos整合

Docker 部署 Seata 与 Nacos 整合

运行所使用的 demo项目地址

本文作者：FUNKYE(陈健斌),杭州某互联网公司主程。

前言

直连方式的 Seata 配置博客

Seata 整合 Nacos 配置博客

我们接着前几篇篇的基础上去配置 nacos 做配置中心跟 dubbo 注册中心.

准备工作

​ 1.安装 docker

yum -y install docker

​ 2.创建 nacos 与 seata 的数据库

​ 3.拉取 nacos 以及 seata 镜像并运行

docker run -d --name nacos -p 8848:8848 -e MODE=standalone -e MYSQL_MASTER_SERVICE_HOST=你的mysql所在ip -e MYSQL_MASTER_SERVICE_DB_NAME=nacos -e MYSQL_MASTER_SERVICE_USER=root -e MYSQL_MASTER_SERVICE_PASSWORD=mysql密码 -e MYSQL_SLAVE_SERVICE_HOST=你的mysql所在ip -e SPRING_DATASOURCE_PLATFORM=mysql -e MYSQL_DATABASE_NUM=1 nacos/nacos-server:latest

docker run -d --name seata -p 8091:8091 -e SEATA_IP=你想指定的ip -e SEATA_PORT=8091 seataio/seata-server:1.4.2

Seata 配置

​ 1.由于 seata 容器内没有内置 vim,我们可以直接将要文件夹 cp 到宿主机外来编辑好了,再 cp 回去

docker cp 容器id:seata-server/resources 你想放置的目录

​ 2.使用如下代码获取两个容器的 ip 地址

docker inspect --format='{{.NetworkSettings.IPAddress}}' ID/NAMES

​ 3.nacos-config.txt 编辑为如下内容

transport.type=TCP
transport.server=NIO
transport.heartbeat=true
transport.enableClientBatchSendRequest=false
transport.threadFactory.bossThreadPrefix=NettyBoss
transport.threadFactory.workerThreadPrefix=NettyServerNIOWorker

详细参数配置请点此处

​ 4.registry.conf 编辑为如下内容

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    serverAddr = "nacos容器ip:8848"
    namespace = ""
    cluster = "default"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"

  nacos {
    serverAddr = "nacos容器ip:8848"
    namespace = ""
  }
}

​ 5.配置完成后使用如下命令,把修改完成的 registry.conf 复制到容器中,并重启查看日志运行

docker cp /home/seata/resources/registry.conf seata:seata-server/resources/
docker restart seata
docker logs -f seata

​ 6.运行 nacos-config.sh 导入 Nacos 配置

eg: sh ${SEATAPATH}/script/config-center/nacos/nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t 5a3c7d6c-f497-4d68-a71a-2e5e3340b3ca -u username -w password

具体参数释义参考：配置导入说明

​ 7.登录 nacos 控制中心查看

​ 如图所示便是成功了.

进行调试

​ 1.拉取博文中所示的项目,修改 test-service 的 application.yml 与 registry.conf

registry {
  type = "nacos"
  nacos {
    serverAddr = "宿主机ip:8848"
    namespace = ""
    cluster = "default"
  }
}
config {
  type = "nacos"
  nacos {
    serverAddr = "宿主机ip:8848"
    namespace = ""
    cluster = "default"
  }
}

server:
  port: 38888
spring:
  application:
      name: test-service
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://mysqlip:3306/test?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: root
    password: 123456
dubbo:
  protocol:
    threadpool: cached
  scan:
    base-packages: com.example
  application:
    qos-enable: false
    name: testserver
  registry:
    id: my-registry
    address:  nacos://宿主机ip:8848
mybatis-plus:
  mapper-locations: classpath:/mapper/*Mapper.xml
  typeAliasesPackage: org.test.entity
  global-config:
    db-config:
      field-strategy: not-empty
      id-type: auto
      db-type: mysql
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    auto-mapping-unknown-column-behavior: none

​ 2.把修改完成的 registry.conf 复制到 test-client-resources 中,并修改 application

spring:
  application:
     name: test
  datasource:
     driver-class-name: com.mysql.cj.jdbc.Driver
     url: jdbc:mysql://mysqlIp:3306/test?userSSL=true&useUnicode=true&characterEncoding=UTF8&serverTimezone=Asia/Shanghai
     username: root
     password: 123456
  mvc:
    servlet:
      load-on-startup: 1
  http:
    encoding:
            force: true
            charset: utf-8
            enabled: true
    multipart:
      max-file-size: 10MB
      max-request-size: 10MB
dubbo:
  registry:
    id: my-registry
    address:  nacos://宿主机ip:8848
  application:
    name: dubbo-demo-client
    qos-enable: false
server:
  port: 28888
  max-http-header-size: 8192
  address: 0.0.0.0
  tomcat:
    max-http-post-size: 104857600

​ 4. 在每个所涉及的 db 执行 undo_log 脚本.

CREATE TABLE IF NOT EXISTS `undo_log`
(
    `branch_id`     BIGINT       NOT NULL COMMENT 'branch transaction id',
    `xid`           VARCHAR(128) NOT NULL COMMENT 'global transaction id',
    `context`       VARCHAR(128) NOT NULL COMMENT 'undo_log context,such as serialization',
    `rollback_info` LONGBLOB     NOT NULL COMMENT 'rollback info',
    `log_status`    INT(11)      NOT NULL COMMENT '0:normal status,1:defense status',
    `log_created`   DATETIME(6)  NOT NULL COMMENT 'create datetime',
    `log_modified`  DATETIME(6)  NOT NULL COMMENT 'modify datetime',
    UNIQUE KEY `ux_undo_log` (`xid`, `branch_id`)
) ENGINE = InnoDB
  AUTO_INCREMENT = 1
  DEFAULT CHARSET = utf8 COMMENT ='AT transaction mode undo table';

​ 5.依次运行 test-service,test-client.

​ 6.查看 nacos 中服务列表是否如下图所示
