Seata安装-修改配置文件
下载编译好的文件压缩包以后，主要修改Conf文件夹中的配置文件，使用Nacos服务注册以及配置管理。看要修改的注释
seata:
config:
# support: nacos, consul, apollo, zk, etcd3
type: nacos #修改成nacos配置管理
nacos:
server-addr: 127.0.0.1:8848
namespace: 6f64d848-9358-4630-baf4-0d315b8b8ed1 #命名空间这里填写nacos生成的id
group: SEATA_GROUP #设一个组
username: nacos #nacos用户名
password: nacos #nacos密码
data-id: seataServer.properties #nacos新建的配置文件的data-id
registry:
# support: nacos, eureka, redis, zk, consul, etcd3, sofa
type: nacos
preferred-networks: 192.168.* #允许注册的IP地址头
nacos:
application: seata-server
server-addr: 127.0.0.1:8848
group: SEATA_GROUP #注册组
namespace: 6f64d848-9358-4630-baf4-0d315b8b8ed1 #命名空间这里填写nacos生成的id
cluster: default
username: nacos #nacos用户名
password: nacos #nacos密码
配置文件也可按application.example.yml实例中的配置设置，注意不要用tab替代4个空格
配置Nacos服务
可查看Spring Cloud Alibaba 容器化部署最佳实践 | 本地部署版本 | Nacos组件安装 安装Nacos。
创建seata配置
在Nacos新建命名空间。
新建配置
不管其他提示直接发布
配置文件填下面填的是如下内容，主要修改MySQL的配置项

安装数据库
把seata-server-1.5.2\seata\script\server\db文件夹中的MySQL数据库文件导入seata数据库中。注意是utf8mb4模式
启动Seata服务
window下运行seata-server.bat文件或者使用如下快捷脚本，修改成自己的路径
Set ws = CreateObject("Wscript.Shell")
ws.run "cmd /k d:&cd seata-server-1.5.2\seata\bin&seata-server.bat"
显示如下内容即表示配置成功。
