一、nacos
1、拉取docker镜像
1 docker pull nacos/nacos-server
2、启动镜像并编辑配置文件
// 启动容器 docker run -d -p 8848:8848 nacos/nacos-server // 进入容器 docker exec -it <container_id> bash // 修改配置文件 vim /home/nacos/conf/application.properties
3、配置文件如下：
spring.datasource.platform=mysql nacos.cmdb.dumpTaskInterval=3600 nacos.cmdb.eventTaskInterval=10 nacos.cmdb.labelTaskInterval=300 nacos.cmdb.loadDataAtStart=false db.num=1 db.url.0=jdbc:mysql://193.168.1.201:3306/nacos_config?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false db.user=<your db username> db.password=<your db password>
4、数据库配置，数据库名nacos_config

5、重启服务
docker restart <contain_id>
6、登录http://HOST:8848/nacos查看是否正常
7、保存镜像
docker commit <container_id> nacos-server:v1.0.0
8、删除原容器，启动新保存的镜像
docker stop <container_id> docker rm <container_id> docker run -d --restart=always -p 8848:8848 -e MODE=standalone nacos-server:v1.0.0
注意：nacos默认是使用cluster集群方式启动的，这里要指定MODE是standalone单机模式，否则会导致seata等服务注册不到nacos。
二、seata
1、拉取seata镜像
docker pull seataio/seata-server
2、运行seata镜像
docker run -d -p 8091:8091 seataio/seata-server
3、将seata容器中的配置文件拷贝出来（改完再同步进去）
docker cp <container_id>:/seata-server/resources/registry.conf ./
docker cp <container_id>:/seata-server/resources/file.conf ./
4、修改配置文件registry.conf
registry部分：说明seata服务注册在哪
config部分：说明seata服务的配置文件在哪，namespace是对应nacos中的命名空间（由于要导入很多seata配置，单独建一个）
5、修改配置文件file.conf（截取了部分）
store { ## lock&session store mode: file、db、redis lock { mode = "db" } session { mode = "db" } ## rsa decryption public key publicKey = "" ## 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://193.168.1.201:3306/seata_config?useUnicode=true&rewriteBatchedStatements=true&serverTimezone=GMT%2B8" user = "<your username>" password = "<your password>" minConn = 5 maxConn = 100 globalTable = "global_table" branchTable = "branch_table" lockTable = "lock_table" queryLimit = 100 maxWait = 5000 }
6、数据库配置，数据库名seata_config
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(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;
7、将配置文件导入容器
docker cp ./registry.conf <container_id>:/seata-server/resources docker cp ./file.conf <container_id>:/seata-server/resources
8、保存容器镜像
docker commit <container_id> seata-server:v1.0.0
9、导入seata配置到nacos（在github上clone一个seata，专门为了将配置导入nacos）
9.1 - 在seata根目录创建config.txt，内容如下：
transport.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.ygs-seata-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.tableMetaCheckerInterval=60000 client.rm.sqlParserType=druid client.rm.reportSuccessEnable=false client.rm.sagaBranchRegisterEnable=false client.tm.commitRetryCount=5 client.tm.rollbackRetryCount=5 client.tm.defaultGlobalTransactionTimeout=60000 client.tm.degradeCheck=false client.tm.degradeCheckAllowTimes=10 client.tm.degradeCheckPeriod=2000 store.mode=db store.publicKey= 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://193.168.1.201:3306/seata_config?useUnicode=true&rewriteBatchedStatements=true&serverTimezone=GMT%2B8 store.db.user=<your username> store.db.password=<your password> 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 store.redis.mode=single store.redis.single.host=127.0.0.1 store.redis.single.port=6379 store.redis.maxConn=10 store.redis.minConn=1 store.redis.maxTotal=100 store.redis.database=0 store.redis.password= store.redis.queryLimit=100 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 client.undo.onlyCareUpdateColumns=true server.undo.logSaveDays=7 server.undo.logDeletePeriod=86400000 client.undo.logTable=undo_log client.undo.compress.enable=true client.undo.compress.type=zip client.undo.compress.threshold=64k log.exceptionRate=100 transport.serialization=seata transport.compressor=none metrics.enabled=false metrics.registryType=compact metrics.exporterList=prometheus metrics.exporterPrometheusPort=9898
9.2 - 在conf目录下，创建nacos-config.sh

" else echo " init nacos config fail. " fi
9.3 - 执行导入命令（-t后面的ID是nacos中命名空间的ID）
./nacos-config.sh -h 193.168.1.201 -p 8848 -g SEATA_GROUP -t cc096f07-22cf-43e3-abcc-79666a72bef2 -u nacos -w nacos
导入成功后：
10、运行容器（注意一定要指定SEATA_IP，否则其他服务找不到，注册地址的IP）
docker run -d --restart=always -p 8091:8091 -e SEATA_IP=193.168.1.201 seata-server:v1.0.0
11、spring-boot配置：
seata: enabled: true application-id: ${spring.application.name} tx-service-group: ygs-seata-group enable-auto-data-source-proxy: true config: type: nacos nacos: server-addr: 193.168.1.201:8848 group : "SEATA_GROUP" namespace: "cc096f07-22cf-43e3-abcc-79666a72bef2" username: "nacos" password: "nacos" registry: type: nacos nacos: application: seata-server server-addr: 193.168.1.201:8848 group: "SEATA_GROUP" namespace: "" username: "nacos" password: "nacos"
需要注意tx-service-group这项，这项配置对应的是nacos导入的配置，里面的值是default。
