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：
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

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
程序执行成功会显示
init nacos config finished, please start seata-server
启动Seata
seata-server.bat（win环境）或seata-server.sh（linux环境）
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
相关说明：p为端口，h为注册服务的ip，m为采用数据库记录模式。
