2.1、server版本：1.4.0 ps：我用的比较老 反正没有出现什么问题
2.2、client项目引入：
<--项目从nacos动态读取配置需要引入-->
3.1、seata 服务端版本：1.4.2
3.2、client项目引入：
进入服务器 使用 ：docker安装 seata
安装步骤：
1、使用docker 拉取 seata 镜像docker pull seataio/seata-server:1.4.2
2、启动镜像：docker run -d --name seata-server -e SEATA_IP=39.xx.xx.xx -e SEATA_PORT=8091 -p 8091:8091 seataio/seata-server:1.4.2
ps：
--name seata-server 注册到nacos的话，服务名称就是seata-server，个人理解相当于springboot 配置中的（spring.application.name=product）欢迎指正。
SEATA_IP=39.xx.xx.xx 服务器的外网ip
-e SEATA_PORT=8091 seata的服务端口
-p 8091:8091 宿主机与容器的端口映射
3、查看运行容器docker ps
红色框内 container id 后面拷贝会用到
ps：如果出现seata-server 代表启动成功
4、修改seata配置文件 4.1、拷贝容器内文件file.conf到容器外的/usr/local/seata径下docker cp 2177b74a2b84:/seata-server/resources/file.conf /usr/local/seata/file.conf
4.2、拷贝容器内文件registry.conf到容器外的/usr/local/seata径下docker cp 2177b74a2b84:/seata-server/resources/registry.conf /usr/local/seata/registry.conf
ps:将 seata的两个配置文件复制到宿主机文件里面-便于更改
4.3、进入 /usr/local/seata文件夹cd /usr/local/seata
5、更改 registry.conf 重点！！！是1.4.2版本更新的新东西（下面有需要修改的内容以及，各个属性的说明。我真是贴心.....）5.1、registry.conf文件全部内容：
registry { # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa type = "nacos" nacos { application = "seata-server" serverAddr = "xx.xx.xx.xx:8848" group = "test" namespace = "57b60655-ab37-48dd-9ab7-xx3c28aa8ab4" 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" aclToken = "" } 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 = "xx.xx.xx.xx:8848" namespace = "57b60655-ab37-48dd-9ab7-xx3c28aa8ab4" group = "test" username = "nacos" password = "nacos" dataId = "seataServer.properties" } consul { serverAddr = "127.0.0.1:8500" aclToken = "" } apollo { appId = "seata-server" ## apolloConfigService will cover apollometa apollometa = "http://192.168.1.204:8801" apolloConfigService = "http://192.168.1.204:8080" namespace = "application" apolloAccesskeySecret = "" cluster = "seata" } zk { serverAddr = "127.0.0.1:2181" sessionTimeout = 6000 connectTimeout = 2000 username = "" password = "" nodePath = "/seata/seata.properties" } etcd3 { serverAddr = "http://localhost:2379" } file { name = "file.conf" }}
registry.conf文件第一部分修改内容 registry.nacos属性说明：
registry.type =nacos 意思是将服务注册到nacos（registry.type指定nacos后就只设置registry.nacos中的属性就好了）
registry.nacos.application= "seata-server" seata在nacos中的服务名称
registry.nacos.serverAddr= ""xx.xx.xx.xx:8848" nacos的访问地址|端口
registry.nacos.group= "test" 下面有图
registry.nacos. namespace = "57b60655-ab37-48dd-9ab7-xxxc28aa8ab4" 下面有图
registry.nacos. cluster = "default" 默认就好了
registry.nacos.username = "nacos" nacos的登录账号
registry.nacos. password = "nacos" nacos的登录密码
---------------------------------------------------------------------------------------------------------------------
registry.conf文件第二部分修改内容 属性说明
config.type ="nacos" seata的配置从nacos读取，config.type ="nacos" 那就只设置config.nacos中的属性就好了
其他 参考registry.nacos (步骤5.1) 中的nacos配置
group = "test"
namespace = "57b60655-ab37-48dd-9ab7-853c28aa8ab4"
dataId = "seataServer.properties" 这个很重要 代表从nacos中
分组group = "test" ； 命名空间namespace = "57b60655-ab37-48dd-9ab7-853c28aa8ab4" seataServer.properties 配置中读取配置
6、更改 file.conf (后面有更改内容，以及说明)file.conf文件全部内容：
## transaction log store, only used in seata-serverstore { ## store mode: file、db、redis mode = "db" ## rsa decryption public key publicKey = "" ## file store property file { ## store location dir dir = "sessionStore" # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions maxBranchSessionSize = 16384 # globe session size , if exceeded throws exceptions maxGlobalSessionSize = 512 # file buffer size , if exceeded allocate new buffer fileWriteBufferCacheSize = 16384 # when recover batch read size sessionReloadReadSize = 100 # async, sync flushDiskMode = async } ## database store property db { ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc. datasource = "druid" ## mysql/oracle/postgresql/h2/oceanbase etc. dbType = "mysql" driverClassName = "com.mysql.cj.jdbc.Driver" ## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param url = "jdbc:mysql://xx.xx.xx.xx:3306/seata?useSSL=true&serverTimezone=GMT" user = "seata" password = "seata" minConn = 5 maxConn = 100 globalTable = "global_table" branchTable = "branch_table" lockTable = "lock_table" queryLimit = 100 maxWait = 5000 } ## redis store property redis { ## redis mode: single、sentinel mode = "single" ## single mode property single { host = "127.0.0.1" port = "6379" } ## sentinel mode property sentinel { masterName = "" ## such as "10.28.235.65:26379,10.28.235.65:26380,10.28.235.65:26381" sentinelHosts = "" } password = "" database = "0" minConn = 1 maxConn = 10 maxTotal = 100 queryLimit = 100 }}
根据个人理解 在registry.conf中的 registry.conf.type=nacos时 其实不用设置这个文件-仅仅个理解，没有去验证，也没有找到说明相关问题的文章。。。。。（得到了证实，只有registry.conf.type = file的时候才会读取这个文件）
---------------------------------------------------------------------------------------------------------
store.mode=db 意思是 seata在使用过程中开启事务时会产生临时数据以及回滚数据 使用数据库保存（ 设置了 store.mode=db之后 只设置store.db的属性就可以了）
store.db.datasource = "druid"
store.db.dbType = "mysql"
store.db. driverClassName = "com.mysql.cj.jdbc.Driver"
store.db.url = "jdbc:mysql://xx.xx.xx.xx:3306/seata?useSSL=true&serverTimezone=GMT"
xx.xx.xx.xx:3306/seata 替换成自己的数据库路径
store.db.user = "seata" 数据库账号
store.db. password = "seata" 数据库密码
其他的根据需要更改.......
注意：
store.db. driverClassName = "com.mysql.cj.jdbc.Driver" 我使用的数据库是mysql8如果使用mysql5的话 改成的 store.db. driverClassName = "com.mysql.jdbc.Driver"
-----------------------------------------------------------
7、将修改好的文件复制回docker容器内docker cp file.conf 2177b74a2b84:/seata-server/resources/file.confdocker cp registry.conf 2177b74a2b84:/seata-server/resources/registry.conf
8、上传seata配置文件到nacos上传配置这一步的目的说明：
docker中运行的 seata-server 会从nacos中读取配置 ，如果想修改seata的配置就从nacos修改，为了方便
创建配置时要与registry.conf文件中的
----------重点-------------
registry.conf.group = "test"；
registry.conf.namespace = ""57b60655-ab37-48dd-9ab7-xx3c28aa8ab4""；
dataId = "seataServer.properties"
值一定要 一 一对应起来
----------重点-------------
8.1、nacos和seata配置文件说明 8.2、seataServer.properties配置 8.3、 配置内容client.tm.defaultGlobalTransactionTimeout=60000client.tm.degradeCheck=falseclient.tm.degradeCheckAllowTimes=10client.tm.degradeCheckPeriod=2000client.tm.interceptorOrder=-2147482648store.mode=dbstore.lock.mode=dbstore.session.mode=filestore.publicKey=store.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://xx.xx.xx.xx.com:3306/seata?useSSL=true&serverTimezone=GMTstore.db.user=seatastore.db.password=seatastore.db.minConn=5store.db.maxConn=30store.db.globalTable=global_tablestore.db.branchTable=branch_tablestore.db.distributedLockTable=distributed_lockstore.db.queryLimit=100store.db.lockTable=lock_tablestore.db.maxWait=5000store.redis.mode=singlestore.redis.single.host=127.0.0.1store.redis.single.port=6379store.redis.sentinel.masterName=store.redis.sentinel.sentinelHosts=store.redis.maxConn=10store.redis.minConn=1store.redis.maxTotal=100store.redis.database=0store.redis.password=store.redis.queryLimit=100server.recovery.committingRetryPeriod=1000server.recovery.asynCommittingRetryPeriod=1000server.recovery.rollbackingRetryPeriod=1000server.recovery.timeoutRetryPeriod=1000server.maxCommitRetryTimeout=-1server.maxRollbackRetryTimeout=-1server.rollbackRetryTimeoutUnlockEnable=falseserver.distributedLockExpireTime=10000client.undo.dataValidation=trueclient.undo.logSerialization=jacksonclient.undo.onlyCareUpdateColumns=trueserver.undo.logSaveDays=7server.undo.logDeletePeriod=86400000client.undo.logTable=undo_logclient.undo.compress.enable=trueclient.undo.compress.type=zipclient.undo.compress.threshold=64klog.exceptionRate=100transport.serialization=seatatransport.compressor=nonemetrics.enabled=falsemetrics.registryType=compactmetrics.exporterList=prometheusmetrics.exporterPrometheusPort=9898tcc.fence.logTableName=tcc_fence_logtcc.fence.cleanPeriod=1hserver.session.branchAsyncQueueSize=5000server.session.enableBranchAsyncRemove=trueservice.vgroupMapping.default_tx_group=defaultservice.vgroupMapping.uat_tx_group=defaultservice.vgroupMapping.test_tx_group=defaultservice.vgroupMapping.prod_tx_group=default

这几个配置分别对应不同的项目环境使用的事务组；配置内容很重要

9、重启 seatadocker restart 2177b74a2b84
10、创建表 10.1、将你在file.conf的中设置的数据库中创建3张表CREATE TABLE `lock_table` ( `row_key` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `xid` varchar(96) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `transaction_id` mediumtext CHARACTER SET utf8 COLLATE utf8_general_ci NULL, `branch_id` mediumtext CHARACTER SET utf8 COLLATE utf8_general_ci NULL, `resource_id` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `table_name` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `pk` varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `gmt_create` datetime(0) NULL DEFAULT NULL, `gmt_modified` datetime(0) NULL DEFAULT NULL, PRIMARY KEY (`row_key`) USING BTREE) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '存储锁表' ROW_FORMAT = Dynamic;CREATE TABLE `global_table` ( `xid` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `transaction_id` bigint(20) NULL DEFAULT NULL, `status` tinyint(4) NOT NULL, `application_id` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `transaction_service_group` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `transaction_name` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `timeout` int(11) NULL DEFAULT NULL, `begin_time` bigint(20) NULL DEFAULT NULL, `application_data` varchar(2000) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `gmt_create` datetime(0) NULL DEFAULT NULL, `gmt_modified` datetime(0) NULL DEFAULT NULL, PRIMARY KEY (`xid`) USING BTREE, INDEX `idx_gmt_modified_status`(`gmt_modified`, `status`) USING BTREE, INDEX `idx_transaction_id`(`transaction_id`) USING BTREE) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '分支事务表' ROW_FORMAT = Dynamic;CREATE TABLE `branch_table` ( `branch_id` bigint(20) NOT NULL, `xid` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `transaction_id` bigint(20) NULL DEFAULT NULL, `resource_group_id` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `resource_id` varchar(256) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `lock_key` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `branch_type` varchar(8) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `status` tinyint(4) NULL DEFAULT NULL, `client_id` varchar(64) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `application_data` varchar(2000) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, `gmt_create` datetime(0) NULL DEFAULT NULL, `gmt_modified` datetime(0) NULL DEFAULT NULL, PRIMARY KEY (`branch_id`) USING BTREE, INDEX `idx_xid`(`xid`) USING BTREE) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '全局事务表' ROW_FORMAT = Dynamic;
10.2在你项目里连接的数据库中创建一张表CREATE TABLE `undo_log` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `branch_id` bigint(20) NOT NULL, `xid` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `context` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL, `rollback_info` longblob NOT NULL, `log_status` int(11) NOT NULL, `log_created` datetime(0) NOT NULL, `log_modified` datetime(0) NOT NULL, `ext` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL, PRIMARY KEY (`id`) USING BTREE, UNIQUE INDEX `ux_undo_log`(`xid`, `branch_id`) USING BTREE) ENGINE = InnoDB AUTO_INCREMENT = 5 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
三、项目内配置文件： 1、yml配置这是application-dev.yml
seata.service.vgroupMapping.default_tx_group: defaultseata.tx-service-group: default_tx_group 必须是一个值如果uat环境可以更改值--前提必须 seataServer.properties 文件内有这个值（8.3步骤后面红色说明！）seata.service.vgroupMapping.uat_tx_group: defaultseata.tx-service-group: uat_tx_group
#分布式事务 seata 配置seata: service: vgroupMapping: default_tx_group: default #default_tx_group分组名称必须要跟tx-service-group的值一样 #指定事务分组 分组必须在 nacos seataServer.properties配置中有 tx-service-group: default_tx_group config: type: nacos nacos: #nacos地址 serverAddr: xx.xx.xx.xx:8848 group: test namespace: 57b60655-ab37-48dd-9ab7-853c28aa8ab4 userName: nacos password: nacos #读取配置文件的 dataId 重要！！！！ dataId: "seataServer.properties" registry: type: nacos nacos: application: seata-server server-addr: xx.xx.xx.xx:8848 group: test namespace: 57b60655-ab37-48dd-9ab7-853c28aa8ab4 userName: nacos password: nacos
2、@GlobalTransactional 添加注解开启事务@RestController@RequestMapping("/locationTest")public class LocationTest { @RequestMapping("/testEmail") @UnLogin @GlobalTransactional public int testEmail() { System.out.println(1); return 1; }}
3、测试事务开启4、docker内seata日志文件打印正常
查看日志命令:docker logs 2177b74a2b84(容器id-container Id)
5、数据库配置的全局事务id保存作者说明：
