基于Docker的Seata1.4.2的Nacos2.0.3服务注册和配置管理

版本

Docker version: 20.10.7, build f0df350
Seata version: 1.4.2
Nacos version: 2.0.3
Mysql version: 8.0.25

容器制作

Docker Nacos 2.0.3容器制作并运行
Nacos 2.x需要多开两个端口 相关见Nacos 2.0.0 兼容性文档

docker run --name nacos-standalone-2.0.3 \ 
      -e MODE=standalone 
      -d 
      -p 8848:8848
      -p 9849:9849 
      -p 9848:9848 
      nacos/nacos-server:2.0.3

制作Seata Server容器之前 下载seata1.4.2的脚本及配置文件

seata 1.4.2

• /client 是客户端有关的一些配置及脚本文件
• /config-center 是要推送到配置中心的一些配置 这里使用nacos
• /logstash/config 日志相关
• /server 服务端相关的配置
  进入配置目录，向nacos推送配置 你可以先修改 本地目录/seata/script/config-center/config.txt的内容 然后再推送 也可以直接推送 后面在nacos里面改

cd 本地目录/seata/script/config-center/nacos
sh nacos-config.sh 127.0.0.1

推送完毕后可以在nacos中看到我们推送的配置

Nacos中的Seata Server配置

在本地目录中/seata/script/server/config/目录下 只保留 registry.conf 如果你喜欢yaml格式也可以只保留registry.yml
编辑registry.conf 这里注释以及用不到的配置项删除了

## https://github.com/seata/seata/blob/1.4.2/script/server/config/registry.conf
registry {
  type = "nacos"
  nacos {
    application = "seata-server"
    # 192.168.*.* macOS 可以通过 ifconfig | grep cast 查看
    serverAddr = "局域网IP:8848"
    group = "SEATA_GROUP"
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}
config {
  type = "nacos"
  nacos {
   serverAddr = "局域网IP:8848"
   group = "SEATA_GROUP"
   username = "nacos"
   password = "nacos"
  }
}

Docker Seata Server容器制作并运行 将刚才修改的registry.conf目录挂载到容器的/root/seta-config 具体见使用 Docker 部署Seata Server 的 "使用自定义配置" 内容

docker run --name seata-server-1.4.2 \
        -d -p 8091:8091 \
        -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \
        -v 本地目录/seata/script/server/config:/root/seata-config   \
        seataio/seata-server:1.4.2

如果将配置中store.mode=file改为store.mode=db
那么同时还需要在本地的MySQL新建一个seata数据库，并在该库下执行脚本mysql.sql脚本，再修改
store.db.url=jdbc:mysql://局域网IP:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=用户名
store.db.password=密码
