一、配置数据库

create database seata;use seata;-- -------------------------------- The script used when storeMode is 'db' ---------------------------------- the table to store GlobalSession dataCREATE 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 dataCREATE 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 dataCREATE 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=TCPtransport.server=NIOtransport.heartbeat=truetransport.enableClientBatchSendRequest=falsetransport.threadFactory.bossThreadPrefix=NettyBosstransport.threadFactory.workerThreadPrefix=NettyServerNIOWorkertransport.threadFactory.serverExecutorThreadPrefix=NettyServerBizHandlertransport.threadFactory.shareBossWorker=falsetransport.threadFactory.clientSelectorThreadPrefix=NettyClientSelectortransport.threadFactory.clientSelectorThreadSize=1transport.threadFactory.clientWorkerThreadPrefix=NettyClientWorkerThreadtransport.threadFactory.bossThreadSize=1transport.threadFactory.workerThreadSize=defaulttransport.shutdown.wait=3service.vgroupMapping.storage-service-group=defaultservice.vgroupMapping.order-service-group=defaultservice.default.grouplist=127.0.0.1:8091service.enableDegrade=falseservice.disableGlobalTransaction=falseclient.rm.asyncCommitBufferLimit=10000client.rm.lock.retryInterval=10client.rm.lock.retryTimes=30client.rm.lock.retryPolicyBranchRollbackOnConflict=trueclient.rm.reportRetryCount=5client.rm.tableMetaCheckEnable=falseclient.rm.sqlParserType=druidclient.rm.reportSuccessEnable=falseclient.rm.sagaBranchRegisterEnable=falseclient.tm.commitRetryCount=5client.tm.rollbackRetryCount=5store.mode=dbstore.file.dir=file_store/datastore.file.maxBranchSessionSize=16384store.file.maxGlobalSessionSize=512store.file.fileWriteBufferCacheSize=16384store.file.flushDiskMode=asyncstore.file.sessionReloadReadSize=100store.db.datasource=druidstore.db.dbType=mysqlstore.db.driverClassName=com.mysql.cj.jdbc.Driverstore.db.url=jdbc:mysql://localhost:3306/seata?useUnicode=truestore.db.user=gueststore.db.password=123456store.db.minConn=5store.db.maxConn=30store.db.globalTable=global_tablestore.db.branchTable=branch_tablestore.db.queryLimit=100store.db.lockTable=lock_tablestore.db.maxWait=5000server.recovery.committingRetryPeriod=1000server.recovery.asynCommittingRetryPeriod=1000server.recovery.rollbackingRetryPeriod=1000server.recovery.timeoutRetryPeriod=1000server.maxCommitRetryTimeout=-1server.maxRollbackRetryTimeout=-1server.rollbackRetryTimeoutUnlockEnable=falseclient.undo.dataValidation=trueclient.undo.logSerialization=jacksonserver.undo.logSaveDays=7server.undo.logDeletePeriod=86400000client.undo.logTable=undo_logclient.log.exceptionRate=100transport.serialization=seatatransport.compressor=nonemetrics.enabled=falsemetrics.registryType=compactmetrics.exporterList=prometheusmetrics.exporterPrometheusPort=9898

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: defaultseata:    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

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

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