一、简介

本文主要描述Nacos及Seata在Windows环境下环境搭建

下载相关软件：

Nacos-1.1.4
Seata-0.9.0

二、安装

2.1安装Nacos

解压nacos-server-1.1.4.zip，进入nacos/bin，双击运行startup.cmd，如果是在Linux下，则sh startup.sh -m standalone 在浏览器打开Nacos web 控制台：http://localhost:8848/nacos/index.html，输入nacos的账号和密码，分别为nacos：nacos

2.2安装Seata

解压seata-server-0.9.0.zip，进入seata/conf，修改registry.conf配置

目前seata支持如下的file、nacos 、apollo、zk、consul的注册中心和配置中心。这里使用nacos。将type改为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的命名空间默认为public
cluster="default" #集群设置未默认 default

修改conf/nacos-config.txt配置

transport.type=TCP transport.server=NIO transport.heartbeat=true transport.thread-factory.boss-thread-prefix=NettyBoss transport.thread-factory.worker-thread-prefix=NettyServerNIOWorker transport.thread-factory.server-executor-thread-prefix=NettyServerBizHandler transport.thread-factory.share-boss-worker=false transport.thread-factory.client-selector-thread-prefix=NettyClientSelector transport.thread-factory.client-selector-thread-size=1 transport.thread-factory.client-worker-thread-prefix=NettyClientWorkerThread transport.thread-factory.boss-thread-size=1 transport.thread-factory.worker-thread-size=8 transport.shutdown.wait=3 service.vgroup_mapping.my_test_tx_group=default service.enableDegrade=false service.disable=false service.max.commit.retry.timeout=-1 service.max.rollback.retry.timeout=-1 client.async.commit.buffer.limit=10000 client.lock.retry.internal=10 client.lock.retry.times=30 client.lock.retry.policy.branch-rollback-on-conflict=true client.table.meta.check.enable=true client.report.retry.count=5 client.tm.commit.retry.count=1 client.tm.rollback.retry.count=1 store.mode=db store.file.dir=file_store/data store.file.max-branch-session-size=16384 store.file.max-global-session-size=512 store.file.file-write-buffer-cache-size=16384 store.file.flush-disk-mode=async store.file.session.reload.read_size=100 store.db.datasource=dbcp store.db.db-type=mysql store.db.driver-class-name=com.mysql.jdbc.Driver store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true store.db.user=root store.db.password=root store.db.min-conn=1 store.db.max-conn=3 store.db.global.table=global_table store.db.branch.table=branch_table store.db.query-limit=100 store.db.lock-table=lock_table recovery.committing-retry-period=1000 recovery.asyn-committing-retry-period=1000 recovery.rollbacking-retry-period=1000 recovery.timeout-retry-period=1000 transaction.undo.data.validation=true transaction.undo.log.serialization=jackson transaction.undo.log.save.days=7 transaction.undo.log.delete.period=86400000 transaction.undo.log.table=undo_log transport.serialization=seata transport.compressor=none metrics.enabled=false metrics.registry-type=compact metrics.exporter-list=prometheus metrics.exporter-prometheus-port=9898 support.spring.datasource.autoproxy=false

这里主要修改了如下几项：

store.mode :存储模式默认file 这里我修改为db 模式，并且需要三个表global_table、branch_table和lock_table store.db.driver-class-name：默认没有，会报错。添加了 com.mysql.jdbc.Driver store.db.datasource=dbcp ：数据源 dbcp store.db.db-type=mysql : 存储数据库的类型为mysql store.db.url=jdbc:mysql://127.0.0.1:3306/seata?useUnicode=true #修改为自己的数据库url、port、数据库名称 store.db.user=root :数据库的账号 store.db.password=123456 :数据库的密码

db模式下的所需的三个表的数据库脚本位于seata\conf\db_store.sql

将Seata配置添加到Nacos中

Windows（需要安装Python环境）下运行：python nacos-config.py localhost Linux下运行：sh ./seata-server.sh
