Windows下搭建Nacos及Seata

一、簡介

本文主要描述Nacos及Seata在Windows環境下環境搭建

下載相關軟件：

• Nacos-1.1.4
• Seata-0.9.0

二、安裝

2.1安裝Nacos

解壓nacos-server-1.1.4.zip，進入nacos/bin，雙擊運行startup.cmd，如果是在Linux下，則sh startup.sh -m standalone
在瀏覽器打開Nacos web 控制台：http://localhost:8848/nacos/index.html，輸入nacos的賬號和密碼，分別為nacos：nacos

2.2安裝Seata

解壓seata-server-0.9.0.zip，進入seata/conf，修改registry.conf配置

目前seata支持如下的file、nacos 、apollo、zk、consul的注冊中心和配置中心。這里使用nacos。將type改為nacos

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    serverAddr = "localhost"
    namespace = "public"
    cluster = "default"
  }
  eureka {
    serviceUrl = "http://localhost:8761/eureka"
    application = "default"
    weight = "1"
  }
  redis {
    serverAddr = "localhost:6379"
    db = "0"
  }
  zk {
    cluster = "default"
    serverAddr = "127.0.0.1:2181"
    session.timeout = 6000
    connect.timeout = 2000
  }
  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 = "file"

  nacos {
    serverAddr = "localhost"
    namespace = "public"
    cluster = "default"
  }
  consul {
    serverAddr = "127.0.0.1:8500"
  }
  apollo {
    app.id = "seata-server"
    apollo.meta = "http://192.168.1.204:8801"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    session.timeout = 6000
    connect.timeout = 2000
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

• serverAddr="localhost" #nacos 的地址
• namespace="public" #nacos的命名空間默認為public
• cluster="default" #集群設置未默認 default

修改conf/nacos-config.txt配置

這里主要修改了如下幾項：

store.mode :存儲模式 默認file 這里我修改為db 模式 ，並且需要三個表global_table、branch_table和lock_table
store.db.driver-class-name： 默認沒有，會報錯。添加了 com.mysql.jdbc.Driver
store.db.datasource=dbcp ：數據源 dbcp
store.db.db-type=mysql : 存儲數據庫的類型為mysql
store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true #修改為自己的數據庫url、port、數據庫名稱
store.db.user=root :數據庫的賬號
store.db.password=123456 :數據庫的密碼

db模式下的所需的三個表的數據庫腳本位於seata\conf\db_store.sql

將Seata配置添加到Nacos中

Windows（需要安裝Python環境）下運行：python nacos-config.py localhost
Linux下運行：sh ./seata-server.sh

程序執行成功會顯示

init nacos config finished, please start seata-server

啟動Seata

seata-server.bat（win環境）或seata-server.sh（linux環境）

Windows:

seata-server.bat -p 9200 -h 127.0.0.1 -m db

Linux:

sh ./seata-server.sh -p 9200 -h 127.0.0.1 -m db

相關說明：p為端口，h為注冊服務的ip，m為采用數據庫記錄模式。
