1.4.2

启动

通过环境变量SEATA_CONFIG_NAME指定配置文件位置/root/seata-config/registry.conf

docker run --name seata-server \ -p 8091:8091 \ -e SEATA_CONFIG_NAME=file:/root/seata-config/registry \ -v /User/seata/config:/root/seata-config \ seataio/seata-server配置文件
实现高可用需要依赖注册中心，配置中心，数据库

registry.conf

registry { type = "nacos" nacos { application = "seata-server" serverAddr = "192.168.199.2" namespace = "test" group = "SEATA_GROUP" cluster = "default" username = "" password = "" }}config { type = "nacos" nacos { serverAddr = "192.168.199.2" namespace = "test" group = "SEATA_GROUP" username = "" password = "" }}NACOS配置
注：使用nacos配置，需要在对应分组(SEATA_GROUP)下针对配置项目逐条配置文本值，而不是创建包含所有配置的properties文件，可以使用官方源码中的

全部可用配置

1. 使用数据库
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://192.168.199.2:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root

store.db.password=123456

创建数据库-- -------------------------------- 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(128), `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;异常处理

1. 客户端报错 Data too long for column ‘application_id'
io.seata.core.exception.TmTransactionException: TransactionException[begin global request failed. xid=null, msg=Data truncation: Data too long for column ‘application_id' at row 1]

seata数据库global_table.application_id字段默认长度为varchar(32)，如果客户端应用ID超长则报此错

手动修改字段类型增加长度即可
