系统环境
docker desktop for windows v4.23.0
nacos、mysql、seata三者都在bridge网络中
docker run -itd \ -e MODE=standalone -e NACOS_SERVER_PORT=8848 -p 8848:8848 --name=nacos_standalone nacos/nacos-server:v2.3.0
docker run -itd \ -e MYSQL_ROOT_PASSWORD=1009 -p 3306:3306 --name=mysql_itcast mysql:5.7
$ docker network inspect bridge
假设这里nacos是172.17.0.3,mysql是172.17.0.2
ipconfig /all
这里假设宿主机ip为192.168.1.102
之后遇到上述三个ip,记得写成自己的
在mysql_itcast中新建seata数据库,然后导入以下脚本
-- -------------------------------- 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_status_gmt_modified` (`status` , `gmt_modified`), KEY `idx_transaction_id` (`transaction_id`) ) ENGINE = InnoDB DEFAULT CHARSET = utf8mb4; -- 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 = utf8mb4; -- the table to store lock data CREATE TABLE IF NOT EXISTS `lock_table` ( `row_key` VARCHAR(128) NOT NULL, `xid` VARCHAR(128), `transaction_id` BIGINT, `branch_id` BIGINT NOT NULL, `resource_id` VARCHAR(256), `table_name` VARCHAR(32), `pk` VARCHAR(36), `status` TINYINT NOT NULL DEFAULT '0' COMMENT '0:locked ,1:rollbacking', `gmt_create` DATETIME, `gmt_modified` DATETIME, PRIMARY KEY (`row_key`), KEY `idx_status` (`status`), KEY `idx_branch_id` (`branch_id`), KEY `idx_xid` (`xid`) ) ENGINE = InnoDB DEFAULT CHARSET = utf8mb4; CREATE TABLE IF NOT EXISTS `distributed_lock` ( `lock_key` CHAR(20) NOT NULL, `lock_value` VARCHAR(20) NOT NULL, `expire` BIGINT, primary key (`lock_key`) ) ENGINE = InnoDB DEFAULT CHARSET = utf8mb4; INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('AsyncCommitting', ' ', 0); INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryCommitting', ' ', 0); INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0); INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);
访问Nacos网页,一般是http://localhost:8848/nacos/,新建一个配置seataServer.properties
具体内容如下:
store.mode=db #-----db----- store.db.datasource=druid store.db.dbType=mysql # 需要根据mysql的版本调整driverClassName # mysql8及以上版本对应的driver:com.mysql.cj.jdbc.Driver # mysql8以下版本的driver:com.mysql.jdbc.Driver store.db.driverClassName=com.mysql.jdbc.Driver store.db.url=jdbc:mysql://172.17.0.2:3306/seata?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false store.db.user= root store.db.password=1009 # 数据库初始连接数 store.db.minConn=1 # 数据库最大连接数 store.db.maxConn=20 # 获取连接时最大等待时间 默认5000,单位毫秒 store.db.maxWait=5000 # 全局事务表名 默认global_table store.db.globalTable=global_table # 分支事务表名 默认branch_table store.db.branchTable=branch_table # 全局锁表名 默认lock_table store.db.lockTable=lock_table store.db.distributedLockTable=distributed_lock # 查询全局事务一次的最大条数 默认100 store.db.queryLimit=100 # undo保留天数 默认7天,log_status=1(附录3)和未正常清理的undo server.undo.logSaveDays=7 # undo清理线程间隔时间 默认86400000,单位毫秒 server.undo.logDeletePeriod=86400000 # 二阶段提交重试超时时长 单位ms,s,m,h,d,对应毫秒,秒,分,小时,天,默认毫秒。默认值-1表示无限重试 # 公式: timeout>=now-globalTransactionBeginTime,true表示超时则不再重试 # 注: 达到超时时间后将不会做任何重试,有数据不一致风险,除非业务自行可校准数据,否者慎用 server.maxCommitRetryTimeout=-1 # 二阶段回滚重试超时时长 server.maxRollbackRetryTimeout=-1 # 二阶段提交未完成状态全局事务重试提交线程间隔时间 默认1000,单位毫秒 server.recovery.committingRetryPeriod=1000 # 二阶段异步提交状态重试提交线程间隔时间 默认1000,单位毫秒 server.recovery.asynCommittingRetryPeriod=1000 # 二阶段回滚状态重试回滚线程间隔时间 默认1000,单位毫秒 server.recovery.rollbackingRetryPeriod=1000 # 超时状态检测重试线程间隔时间 默认1000,单位毫秒,检测出超时将全局事务置入回滚会话管理器 server.recovery.timeoutRetryPeriod=1000
宿主机新建一个application.yml文件,内容如下
server: port: 7091 spring: application: name: seata-server logging: config: classpath:logback-spring.xml file: path: ${user.home}/logs/seata extend: logstash-appender: destination: 127.0.0.1:4560 kafka-appender: bootstrap-servers: 127.0.0.1:9092 topic: logback_to_logstash console: user: username: seata password: seata seata: config: # support: nacos, consul, apollo, zk, etcd3 type: nacos nacos: server-addr: 172.17.0.3:8848 namespace: group: DEFAULT_GROUP username: nacos password: nacos data-id: seataServer.properties registry: # support: nacos, eureka, redis, zk, consul, etcd3, sofa type: nacos nacos: application: seata-tc-server server-addr: 172.17.0.3:8848 group: DEFAULT_GROUP namespace: # tc集群名称 cluster: SH username: nacos password: nacos # server: # service-port: 8091 #If not configured, the default is '${server.port} + 1000' security: secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017 tokenValidityInMilliseconds: 1800000 ignore: urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login
然后用以下命令运行seata容器
docker run --name seata-server \ -itd \ -p 8091:8091 \ -p 7091:7091 \ -e STORE_MODE=db \ -e SEATA_IP="192.168.1.102" \ -e SEATA_PORT=8091 \ -v "path/to/application.yml:/seata-server/resources/application.yml" \ seataio/seata-server:2.0.0
访问Seata网页,这里是http://192.168.1.102:7091/,输入两个seata后进入系统。
Nacos网页上查看Seata服务详情,ip为宿主机ip,不要是docker容器内网ip就行。
com.alibaba.cloud spring-cloud-starter-alibaba-seata seata-spring-boot-starter io.seata io.seata seata-spring-boot-starter 1.4.2
seata: registry: type: nacos nacos: # tc server-addr: localhost:8848 namespace: "" group: DEFAULT_GROUP application: seata-tc-server # tc服务在nacos中的服务名称 cluster: SH username: nacos password: nacos tx-service-group: seata-demo # 事务组,根据这个获取tc服务的cluster名称 service: vgroup-mapping: # 事务组与TC服务cluster的映射关系 seata-demo: SH
启动微服务后,除了可以看微服务的日志外,还可以看Seata容器日志,出现类似以下日志即为正常
2023-12-30 21:37:35 digest=seata-demo,192.168.222.1,1703943453643 2023-12-30 21:37:35 timestamp=1703943453643 2023-12-30 21:37:35 authVersion=V4 2023-12-30 21:37:35 vgroup=seata-demo 2023-12-30 21:37:35 ip=192.168.222.1 2023-12-30 21:37:35 '},channel:[id: 0x7f82356a, L:/172.17.0.4:8091 - R:/172.17.0.1:35092],client version:2.0.0 2023-12-30 21:37:36 21:37:36.389 INFO --- [rverHandlerThread_1_6_500] [rocessor.server.RegRmProcessor] [ onRegRmMessage] [] : RM register success,message:RegisterRMRequest{resourceIds='jdbc:mysql://localhost:3306/seata_demo', version='2.0.0', applicationId='order-service', transactionServiceGroup='seata-demo', extraData='null'},channel:[id: 0x3a9f4e29, L:/172.17.0.4:8091 - R:/172.17.0.1:35096],client version:2.0.0
网上看到以下各种方法均无效
以下方法有效
一开始为了图方便,给Nacos用过host网络,结果容器程序运行正常,打不开网页,玄学的一批。
也给Seata使用host网络,为了配置文件里面不用自己手动查询nacos和mysql的ip,结果然并卵。
这个是因为很多文档,都只有3张表,少了一张。
官方文档说store.db.distributedLockTable是 1.5.1版本新增的参数。
https://seata.io/zh-cn/docs/user/configurations
但是很多文档和博客,都只有3张表,第4张在哪里呢?
在这里
https://seata.io/zh-cn/docs/ops/deploy-by-docker-compose.html
里面写到nacos注册中心,db存储时会提供 [建表脚本]
以及最后最重要的是,要在Nacos配置中心配置seataServer.properties时,要多加一行
store.db.distributedLockTable=distributed_lock
这点在官网文档都没有提及。
具体参考这个Issue
