docker-compose 部署 Seata整合nacos,Postgresql 为DB存储

环境

详情环境可参考
https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E

我这里

<spring.cloud.alibaba-version>2021.1</spring.cloud.alibaba-version>

所有选择seata版本为 1.3.0

docker-compose 部署seata

前提：已经安装好nacos和postgresql

1. 创建好数据库 名称：seata
   执行以下sql:

-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS public.global_table
(xid                       VARCHAR(128) NOT NULL,transaction_id            BIGINT,status                    SMALLINT     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                TIMESTAMP(0),gmt_modified              TIMESTAMP(0),CONSTRAINT pk_global_table PRIMARY KEY (xid)
);CREATE INDEX idx_status_gmt_modified ON public.global_table (status, gmt_modified);
CREATE INDEX idx_transaction_id ON public.global_table (transaction_id);-- the table to store BranchSession data
CREATE TABLE IF NOT EXISTS public.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            SMALLINT,client_id         VARCHAR(64),application_data  VARCHAR(2000),gmt_create        TIMESTAMP(6),gmt_modified      TIMESTAMP(6),CONSTRAINT pk_branch_table PRIMARY KEY (branch_id)
);CREATE INDEX idx_xid ON public.branch_table (xid);-- the table to store lock data
CREATE TABLE IF NOT EXISTS public.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         SMALLINT     NOT NULL DEFAULT 0,gmt_create     TIMESTAMP(0),gmt_modified   TIMESTAMP(0),CONSTRAINT pk_lock_table PRIMARY KEY (row_key)
);comment on column public.lock_table.status is '0:locked ,1:rollbacking';
CREATE INDEX idx_branch_id ON public.lock_table (branch_id);
CREATE INDEX idx_xid ON public.lock_table (xid);
CREATE INDEX idx_status ON public.lock_table (status);CREATE TABLE distributed_lock (lock_key     VARCHAR(20)  NOT NULL,lock_value        VARCHAR(20)  NOT NULL,expire       BIGINT       NOT NULL,CONSTRAINT pk_distributed_lock_table PRIMARY KEY (lock_key)
);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);

其他的sql可以参考:
https://github.com/seata/seata/tree/develop/script/server/db

服务器层级结构:

2.先运行一个seata容器,目的为了把seata相关的配置文件拷贝处理，方便后续使用

docker run --name seata-server -p 8091:8091 -d  seataio/seata-server:1.3.0

docker cp seata-server:/seata-server /opt/seata/resources

3.然后将该容器删除

docker stop seata-server

docker rm  seata-server

4, 修改后的file.conf

## transaction log store, only used in seata-server
store {## store mode: file、db、redismode = "db"## file store propertyfile {## store location dirdir = "sessionStore"# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptionsmaxBranchSessionSize = 16384# globe session size , if exceeded throws exceptionsmaxGlobalSessionSize = 512# file buffer size , if exceeded allocate new bufferfileWriteBufferCacheSize = 16384# when recover batch read sizesessionReloadReadSize = 100# async, syncflushDiskMode = async}## database store propertydb {## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.## datasource = "druid"## mysql/oracle/postgresql/h2/oceanbase etc.dbType = "postgresql"driverClassName = "org.postgresql.Driver"url = "jdbc:postgresql://101.35.249.216:5432/seata"user = "root"password = "root"minConn = 5maxConn = 30globalTable = "global_table"branchTable = "branch_table"lockTable = "lock_table"queryLimit = 100maxWait = 5000}## redis store propertyredis {host = "127.0.0.1"port = "6379"password = ""database = "0"minConn = 1maxConn = 10queryLimit = 100}}

修改细节如下图:

修改后的registry.conf：

registry {# file 、nacos 、eureka、redis、zk、consul、etcd3、sofatype = "nacos"nacos {application = "seata-server"serverAddr = "nacos.carbonease.cn:80"group = "SEATA_GROUP"namespace = "cfa514ed-1caf-4d2b-8645-8dbee0f3933f"cluster = "default"username = "nacos"password = "Carbonease@2022"}eureka {serviceUrl = "http://localhost:8761/eureka"application = "default"weight = "1"}redis {serverAddr = "localhost:6379"db = 0password = ""cluster = "default"timeout = 0}zk {cluster = "default"serverAddr = "127.0.0.1:2181"sessionTimeout = 6000connectTimeout = 2000username = ""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"}

}

修改细节如下图:


/opt/seata目录下创建 config.txt

修改内容如下:

在 /opt/seata 下创建 scrip目录
在scrip目录下 创建脚本 nacos-config.sh
nacos-config.sh内容如下:

fi

修改sh文件的权限

chmod +x nacos-config.sh

将配置文件推送至Nacos:

bash ./nacos-config.sh -h nacos.carbonease.cn  -p 80  -g SEATA_GROUP -t cfa514ed-1caf-4d2b-8645-8dbee0f3933f

命令格式：

sh nacos-config.sh -h  Nacos地址  -p nacos端口号 -g SEATA_GROUP（此处是配置文件的分组名称，可以不改） -t 在nacos配置的seata命名空间ID

推送成功

创建 docker-compose.yml 文件

version: "3"
services:seata-server:image: seataio/seata-server:1.3.0container_name: seata-serverhostname: seata-serverports:- "8091:8091"environment:- SEATA_PORT=8091- STORE_MODE=db- SEATA_IP=101.35.249.216 ##将此处的IP替换为docker宿主机的IPrestart: 'no'volumes:- "/usr/share/zoneinfo/Asia/Shanghai:/etc/localtime"        #设置系统时区- "/usr/share/zoneinfo/Asia/Shanghai:/etc/timezone"  #设置时区- "./resources:/seata-server/resources"

启动

docker-compose up -d

成功注册上nacos!

springCloud项目整合:

pom文件：

    <!-- seata分布式事务--><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-seata</artifactId><exclusions><exclusion><groupId>io.seata</groupId><artifactId>seata-spring-boot-starter</artifactId></exclusion></exclusions></dependency><dependency><groupId>io.seata</groupId><artifactId>seata-spring-boot-starter</artifactId><version>1.3.0</version></dependency>

客户端和服务端的版本一定要一致，否则可能出现

no available service 'default' found, please make sure registry config correct

yml文件中:

seata:application-id: ${spring.application.name}enabled: truetx-service-group: my_test_tx_group #此处的配置来源于上述步骤中config.txt中的service.vgroupMapping.my_test_tx_group=defaultregistry:type: nacosnacos:server-addr: nacos.carbonease.cn:80 #nacos的连接地址namespace: cfa514ed-1caf-4d2b-8645-8dbee0f3933f      #在nacos中创建的seata命名空间IDgroup: SEATA_GROUP #seata配置的分组名称cluster: defaultusername: nacospassword: Carbonease@2022config:type: nacosnacos:server-addr: nacos.carbonease.cn:80 #nacos的连接地址namespace: cfa514ed-1caf-4d2b-8645-8dbee0f3933f #在nacos中创建的seata命名空间IDgroup: SEATA_GROUP #seata配置的分组名称username: nacospassword: Carbonease@2022service:vgroup-mapping:my_test_tx_group: default #此处的配置来源于上述步骤中config.txt中的service.vgroupMapping.my_test_tx_group=default#注意：此处的my_test_tx_group需要和上面seata.tx-service-group以及config.txt中的配置对应

jdk8以上的需要设置启动参数:

--add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.lang.reflect=ALL-UNNAMED 

否则可能出现:

Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @9d5509a

然后，服务所涉及到的数据库需要加上日志表：

-- 日志表
CREATE TABLE IF NOT EXISTS public.undo_log
(id            BIGINT   NOT NULL,branch_id     BIGINT   NOT NULL,xid           VARCHAR(100) NOT NULL,context       VARCHAR(128) NOT NULL,rollback_info bytea     NOT NULL,log_status    INT          NOT NULL,log_created   TIMESTAMP(6)     NOT NULL,log_modified  TIMESTAMP(6)     NOT NULL,CONSTRAINT pk_undo_log PRIMARY KEY (id)
);
CREATE SEQUENCE undo_log_id_seq START 1;

最后:
服务A 调用 服务B
在服务A的Service上加注解

@GlobalTransactional(rollbackFor = Exception.class)

服务B是Service上加注解

@Transactional(rollbackFor = Exception.class)

大功告成!!
