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:

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
