这个东东整了我2天多。。我有点无语。。本来就很简单的东西。。有点无辜。开发还是本地搞环境好，问题少😂
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
这边主要是把相关配置上传到nacos中，方便seata-center读取
下载nacos-config.sh和config.txt
修改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 transport.server=NIO transport.heartbeat=true transport.enableClientBatchSendRequest=false transport.threadFactory.bossThreadPrefix=NettyBoss transport.threadFactory.workerThreadPrefix=NettyServerNIOWorker transport.threadFactory.serverExecutorThreadPrefix=NettyServerBizHandler transport.threadFactory.shareBossWorker=false transport.threadFactory.clientSelectorThreadPrefix=NettyClientSelector transport.threadFactory.clientSelectorThreadSize=1 transport.threadFactory.clientWorkerThreadPrefix=NettyClientWorkerThread transport.threadFactory.bossThreadSize=1 transport.threadFactory.workerThreadSize=default transport.shutdown.wait=3 service.vgroupMapping.storage-service-group=default service.vgroupMapping.order-service-group=default service.default.grouplist=127.0.0.1:8091 service.enableDegrade=false service.disableGlobalTransaction=false client.rm.asyncCommitBufferLimit=10000 client.rm.lock.retryInterval=10 client.rm.lock.retryTimes=30 client.rm.lock.retryPolicyBranchRollbackOnConflict=true client.rm.reportRetryCount=5 client.rm.tableMetaCheckEnable=false client.rm.sqlParserType=druid client.rm.reportSuccessEnable=false client.rm.sagaBranchRegisterEnable=false client.tm.commitRetryCount=5 client.tm.rollbackRetryCount=5 store.mode=db store.file.dir=file_store/data store.file.maxBranchSessionSize=16384 store.file.maxGlobalSessionSize=512 store.file.fileWriteBufferCacheSize=16384 store.file.flushDiskMode=async store.file.sessionReloadReadSize=100 store.db.datasource=druid store.db.dbType=mysql store.db.driverClassName=com.mysql.cj.jdbc.Driver store.db.url=jdbc:mysql://localhost:3306/seata?useUnicode=true store.db.user=guest store.db.password=123456 store.db.minConn=5 store.db.maxConn=30 store.db.globalTable=global_table store.db.branchTable=branch_table store.db.queryLimit=100 store.db.lockTable=lock_table store.db.maxWait=5000 server.recovery.committingRetryPeriod=1000 server.recovery.asynCommittingRetryPeriod=1000 server.recovery.rollbackingRetryPeriod=1000 server.recovery.timeoutRetryPeriod=1000 server.maxCommitRetryTimeout=-1 server.maxRollbackRetryTimeout=-1 server.rollbackRetryTimeoutUnlockEnable=false client.undo.dataValidation=true client.undo.logSerialization=jackson server.undo.logSaveDays=7 server.undo.logDeletePeriod=86400000 client.undo.logTable=undo_log client.log.exceptionRate=100 transport.serialization=seata transport.compressor=none metrics.enabled=false metrics.registryType=compact metrics.exporterList=prometheus metrics.exporterPrometheusPort=9898
上传配置到nacos
注意点是config.txt放在conf目录外边，nacos-config放在conf文件夹下面
打开nacos-config.sh能看到几个参数，不指定的话就是默认的
./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，正常自己服务和项目都是本地的话照着官方文档基本就OK了
下载最新的二进制安装包
解压
unzip xxx -d /opt
修改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，一定要指明公网IP地址，不然默认客户端拿到的是内网IP，是访问不到的
./bin/seata-server.sh -h 公网ip（和项目同网就不用指定了）
四、配置项目
依赖
compile('com.alibaba.cloud:spring-cloud-starter-alibaba-seata') • 1
yml配置
这边截取了部分相关配置
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

这种比较简单，只需要在nacos上新增一个对应的配置就可以了，配置内容就是这个dataid和group，值是default
