Docker搭建Nacos1.4+Seata1.4+MySQL8

1. 运行nacos容器

docker run -d --name nacos -e MODE=standalone -p 8848:8848 nacos/nacos-server:1.4.0

2. 运行seata容器

docker run -d --name seata -p 8091:8091 seataio/seata-server:1.4.0

3. copy配置文件

mkdir ~/seata-config
docker cp seata:/seata-server/resources  ~/seata-config

4. 删除容器

docker rm -f seata

5. 修改配置文件注册进nacos，配置文件位置： ~/seata-config/registry.conf。若指定命名空间则配置文件进行相应调整，注意namespace的值为命名空间ID

registry {
  type = "nacos"
  loadBalance = "RandomLoadBalance"
  loadBalanceVirtualNodes = 10

  nacos {
    application = "seata-server"
    # 写自己的ip:port
    serverAddr = "localhost:8848"
    group = "SEATA_GROUP"
    # 这里替换自己的namespace ID
    namespace = "seata"
    username = "nacos"
    password = "nacos"
  }
}
config {
  type = "nacos"

  nacos {
    serverAddr = "localhost:8848"
    namespace = "seata"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
}

6. 到github的seata源码库弄来两个文件，config.txt 、nacos/nacos-config.sh

https://github.com/seata/seata/tree/develop/script/config-center

7. 配置文件位置如下

/root/seata-config/nacos-seata/config.txt
/root/seata-config/nacos-seata/nacos/nacos-config.sh

8. 修改config.txt

# 这里值随意，但需与客户端保持一致
service.vgroupMapping.my_test_tx_group=fps_tx_group

store.db.driverClassName=com.mysql.cj.jdbc.Driver
# 这里替换自己的mysql地址
store.db.url=jdbc:mysql://localhost:3306/seata?characterEncoding=utf8&useSSL=false&serverTimezone=UTC
store.db.user=root
store.db.password=root

9. 执行 .sh 文件，将seata配置推送到nacos

cd /root/seata-config/nacos-seata/nacos
bash nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t seata -u nacos -w nacos

10. nacos配置列表

seata配置成功推送至nacos

11. seata服务端，建立seata库，运行sql

https://github.com/seata/seata/blob/develop/script/server/db/mysql.sql

12. 运行seata容器并将配置文件挂载出来

# 这里替换自己的ip
docker run  -d --name seata -p 8091:8091  -e SEATA_IP=127.0.0.1 -e SEATA_CONFIG_NAME=file:/seata-server/resources/registry  -v ~/seata-config:/seata-server/resources seataio/seata-server:1.4.0

13. 查看seata容器日志

docker logs -f seata

14. nacos服务列表

seata服务成功注册至nacos

本案例操作系统为Ubuntu20.04，nacos为单例模式，未使用mysql进行持久化，集群及mysql使用详见官网
