部署seata-server，使用nacos做配置中心和注册中心

1. 下载压缩包，解压

https://github.com/seata/seata/releases
我用的1.5.2版本

2. 建表

script/server/db目录下有建表sql

3. 改配置

config/application.yml

server:
  port: 7091

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: ${user.home}/logs/seata

#登录控制台用的账密
console:
  user:
    username: xxxx
    password: yyyy

#使用nacos做配置中心和注册中心
seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
        serverAddr: xx.xx.xx.xx:8848
        namespace: nnnnnnnnnn
        group: SEATA_GROUP #需要与前面创建的配置文件相对应
        username: uuuuu
        password: ppppp
        file-extension: yml
        dataId: seata-server.yml #需要与前面创建的配置文件相对应
  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    nacos:
        serverAddr: xx.xx.xx.xx:8848
        namespace: nnnnnnnnnn
        group: SEATA_GROUP
        username: uuuuu
        password: ppppp
        application: ${spring.application.name}
  #store:
    # support: file 、 db 、 redis
    #mode: file


  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

4. 添加nacos配置
