这个东东整了我 2 天多。。我有点无语。。原本就很简略的货色。。有点无辜。开发还是本地搞环境好，问题少????

seata/seata

Seata 是什么

一、配置数据库 

create database seata;
use seata;
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`
(`xid`                       VARCHAR(128) NOT NULL,
    `transaction_id`            BIGINT,
    `status`                    TINYINT      NOT NULL,
    `application_id`            VARCHAR(32),
    `transaction_service_group` VARCHAR(32),
    `transaction_name`          VARCHAR(128),
    `timeout`                   INT,
    `begin_time`                BIGINT,
    `application_data`          VARCHAR(2000),
    `gmt_create`                DATETIME,
    `gmt_modified`              DATETIME,
    PRIMARY KEY (`xid`),
    KEY `idx_gmt_modified_status` (`gmt_modified`, `status`),
    KEY `idx_transaction_id` (`transaction_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS `branch_table`
(
    `branch_id`         BIGINT       NOT NULL,
    `xid`               VARCHAR(128) NOT NULL,
    `transaction_id`    BIGINT,
    `resource_group_id` VARCHAR(32),
    `resource_id`       VARCHAR(256),
    `branch_type`       VARCHAR(8),
    `status`            TINYINT,
    `client_id`         VARCHAR(64),
    `application_data`  VARCHAR(2000),
    `gmt_create`        DATETIME(6),
    `gmt_modified`      DATETIME(6),
    PRIMARY KEY (`branch_id`),
    KEY `idx_xid` (`xid`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(`row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(96),
    `transaction_id` BIGINT,
    `branch_id`      BIGINT       NOT NULL,
    `resource_id`    VARCHAR(256),
    `table_name`     VARCHAR(32),
    `pk`             VARCHAR(36),
    `gmt_create`     DATETIME,
    `gmt_modified`   DATETIME,
    PRIMARY KEY (`row_key`),
    KEY `idx_branch_id` (`branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8;

二、配置 nacos

这边次要是把相干配置上传到 nacos 中，不便 seata-center 读取

下载 nacos-config.sh 和 config.txt

seata/seata

批改 config.txt

数据库是 8.0 以上的话，驱动得换成 com.mysql.cj.jdbc.Driver

nsport.type=TCP

上传配置到 nacos

留神点是 config.txt 放在 conf 目录外边，nacos-config 放在 conf 文件夹上面

关上 nacos-config.sh 能看到几个参数，不指定的话就是默认的

ring4all.com/FgE8jEIti9gdI3_TPnrBsKz8dA90)

./nacos-config.sh -h loclahost -p 8848 -g SEAT_GROUP

三、配置 seata-center

这个 seata-center 是配置在阿里云 ECS 上的，所以有很多问题，失常本人服务和我的项目都是本地的话照着官网文档根本就 OK 了

下载最新的二进制安装包

下载核心

解压 

unzip xxx -d /opt

批改 conf/register.conf

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

  nacos {
    application = "seata-server"
    serverAddr = "localhost:8848"
    group = "SEATA_GROUP"
    namespace = "public"
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
  eureka {
    serviceUrl = "http://localhost:8761/eureka"
    application = "default"
    weight = "1"
  }
  redis {
    serverAddr = "localhost:6379"
    db = 0
    password = ""cluster ="default"
    timeout = 0
  }
  zk {
    cluster = "default"
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""password =""
  }
  consul {
    cluster = "default"
    serverAddr = "127.0.0.1:8500"
  }
  etcd3 {
    cluster = "default"
    serverAddr = "http://localhost:2379"
  }
  sofa {
    serverAddr = "127.0.0.1:9603"
    application = "default"
    region = "DEFAULT_ZONE"
    datacenter = "DefaultDataCenter"
    cluster = "default"
    group = "SEATA_GROUP"
    addressWaitTime = "3000"
  }
  file {name = "file.conf"}
}

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

  nacos {
    serverAddr = "localhost:8848"
    namespace = "public"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
  consul {serverAddr = "127.0.0.1:8500"}
  apollo {
    appId = "seata-server"
    apolloMeta = "http://192.168.1.204:8801"
    namespace = "application"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""password =""
  }
  etcd3 {serverAddr = "http://localhost:2379"}
  file {name = "file.conf"}
}

启动

这边有个坑，肯定要指明公网 IP 地址，不然默认客户端拿到的是内网 IP，是拜访不到的 

 ./bin/seata-server.sh -h 公网 ip（和我的项目同网就不必指定了）

四、配置我的项目

依赖 

compile('com.alibaba.cloud:spring-cloud-starter-alibaba-seata')

yml 配置

这边截取了局部相干配置 

spring:
    cloud:
        nacos:
            discovery:
                server-addr: ${dev.nacos.host}:${dev.port.nacos}
        alibaba:
            seata:
                tx-service-group: default
seata:
    registry:
        type: nacos
        nacos:
            server-addr: ${dev.nacos.host}:${dev.port.nacos}
            namespace:
    config:
        type: nacos
        nacos:
            server-addr: ${dev.nacos.host}:${dev.port.nacos}
            namespace:

五、常见问题

没有找到服务

这种比较简单，只须要在 nacos 上新增一个对应的配置就能够了，配置内容就是这个 dataid 和 group，值是 default
