一.下载seata-server

基于我们的项目采用的是

1.spring-cloud Hoxton.RELEASE
2.spring-cloud-alibaba 2.1.1RELEASE

所以seata版本采用0.9.0版本,下载seata-service,并在linux 上部署AT模式

https://github.com/seata/seata/releases/tag/v0.9.0

版本选择

二.修改seata-server配置文件

在seata-service文件夹中修改\seata\conf\registry.conf 与 \seata\conf\file.conf 2个文件

2.1.registry.conf文件

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"   #注册中心采用nacos

  nacos {
    serverAddr = "172.18.44.112:8848"
    namespace = ""
    cluster = "default"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "file"  #配置中心直接使用file模式

  file {
    name = "file.conf"
  }
}

2.2file.conf文件(存储方式采用db->58行,并且修改db信息->82~85行)

transport {
  # tcp udt unix-domain-socket
  type = "TCP"
  #NIO NATIVE
  server = "NIO"
  #enable heartbeat
  heartbeat = true
  #thread factory for netty
  thread-factory {
    boss-thread-prefix = "NettyBoss"
    worker-thread-prefix = "NettyServerNIOWorker"
    server-executor-thread-prefix = "NettyServerBizHandler"
    share-boss-worker = false
    client-selector-thread-prefix = "NettyClientSelector"
    client-selector-thread-size = 1
    client-worker-thread-prefix = "NettyClientWorkerThread"
    # netty boss thread size,will not be used for UDT
    boss-thread-size = 1
    #auto default pin or 8
    worker-thread-size = 8
  }
  shutdown {
    # when destroy server, wait seconds
    wait = 3
  }
  serialization = "seata"
  compressor = "none"
}
service {
  #vgroup->rgroup
  vgroup_mapping.my_test_tx_group = "default"  
#注意这里的名称与客户端yml文件中的spring-cloud-alibaba-seata-tx-service-group 的值一致
  #only support single node
  default.grouplist = "172.18.44.110:8091" #采用service端服务器的ip
  #degrade current not support
  enableDegrade = false
  #disable
  disable = false
  #unit ms,s,m,h,d represents milliseconds, seconds, minutes, hours, days, default permanent
  max.commit.retry.timeout = "-1"
  max.rollback.retry.timeout = "-1"
}

client {
  async.commit.buffer.limit = 10000
  lock {
    retry.internal = 10
    retry.times = 30
  }
  report.retry.count = 5
  tm.commit.retry.count = 1
  tm.rollback.retry.count = 1
}

## transaction log store
store {
  ## store mode: file、db
  mode = "db"   #采用db储存信息

  ## file store
  file {
    dir = "sessionStore"

    # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
    max-branch-session-size = 16384
    # globe session size , if exceeded throws exceptions
    max-global-session-size = 512
    # file buffer size , if exceeded allocate new buffer
    file-write-buffer-cache-size = 16384
    # when recover batch read size
    session.reload.read_size = 100
    # async, sync
    flush-disk-mode = async
  }

  ## database store
  db {
    ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
    datasource = "dbcp"
    ## mysql/oracle/h2/oceanbase etc.
    db-type = "mysql"
    driver-class-name = "com.mysql.jdbc.Driver"     #db的连接信息
    url = "jdbc:mysql://127.0.0.1:3306/seata"
    user = "root"
    password = "root"
    min-conn = 1
    max-conn = 3
    global.table = "global_table"
    branch.table = "branch_table"
    lock-table = "lock_table"
    query-limit = 100
  }
}
lock {
  ## the lock store mode: local、remote
  mode = "remote"

  local {
    ## store locks in user's database
  }

  remote {
    ## store locks in the seata's server
  }
}
recovery {
  #schedule committing retry period in milliseconds
  committing-retry-period = 1000
  #schedule asyn committing retry period in milliseconds
  asyn-committing-retry-period = 1000
  #schedule rollbacking retry period in milliseconds
  rollbacking-retry-period = 1000
  #schedule timeout retry period in milliseconds
  timeout-retry-period = 1000
}

transaction {
  undo.data.validation = true
  undo.log.serialization = "jackson"
  undo.log.save.days = 7
  #schedule delete expired undo_log in milliseconds
  undo.log.delete.period = 86400000
  undo.log.table = "undo_log"
}

## metrics settings
metrics {
  enabled = false
  registry-type = "compact"
  # multi exporters use comma divided
  exporter-list = "prometheus"
  exporter-prometheus-port = 9898
}

support {
  ## spring
  spring {
    # auto proxy the DataSource bean
    datasource.autoproxy = false
  }
}

三.建表

3.1.seata数据库

创建seata数据库 sql位置 /seata/conf/db_store.sql

3.2.undo_log表

业务数据库中建立此表 sql位置 /seata/conf/db_undo_log.sql

如果没有找到相应脚本,可以去官网找一下,这里列出我找到的mysql版本
db_store
undo_log

四.部署

解压 tar zxf seata-server-0.9.0.tar.gz
进入/seata/bin
启动服务端 /seata/bin# sh seata-server.sh

服务端启动信息 客户端连接信息

至此
