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

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/版本说明

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、redis
  mode = "db"

  ## 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 = "postgresql"
    driverClassName = "org.postgresql.Driver"
    url = "jdbc:postgresql://101.35.249.216:5432/seata"
    user = "root"
    password = "root"
    minConn = 5
    maxConn = 30
    globalTable = "global_table"
    branchTable = "branch_table"
    lockTable = "lock_table"
    queryLimit = 100
    maxWait = 5000
  }

  ## redis store property
  redis {
    host = "127.0.0.1"
    port = "6379"
    password = ""
    database = "0"
    minConn = 1
    maxConn = 10
    queryLimit = 100
  }

}

修改细节如下图:

修改后的registry.conf：

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "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 = 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"
  }
  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 = "nacos.carbonease.cn:80"
    namespace = "cfa514ed-1caf-4d2b-8645-8dbee0f3933f"
    group = "SEATA_GROUP"
    username = "nacos"
    password = "Carbonease@2022"
  }
  consul {
    serverAddr = "127.0.0.1:8500"
  }
  apollo {
    appId = "seata-server"
    apolloMeta = "http://192.168.1.204:8801"
    namespace = "application"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

修改细节如下图:

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:

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:1.3.0
    container_name: seata-server
    hostname: seata-server
    ports:
      - "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IP
    restart: '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>

            <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: true
  tx-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=default
  registry:
    type: nacos
    nacos:
      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ID
      group: SEATA_GROUP #seata配置的分组名称
      cluster: default
      username: nacos
      password: Carbonease@2022
  config:
    type: nacos
    nacos:
      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ID
      group: SEATA_GROUP #seata配置的分组名称
      username: nacos
      password: Carbonease@2022
  service:
    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!!
