seata1.8安装部署

1.在nacos里面创建命名空间

 2.下载seata安装包

3.将下载的seata解压，找到seata/script/server/db目录下对应数据库的sql脚本，创建数据库

undo_log.sql

CREATE TABLE `undo_log` (
  `branch_id` bigint(20) NOT NULL COMMENT 'branch transaction id',
  `xid` varchar(128) NOT NULL COMMENT 'global transaction id',
  `context` varchar(128) NOT NULL COMMENT 'undo_log context,such as serialization',
  `rollback_info` longblob NOT NULL COMMENT 'rollback info',
  `log_status` int(11) NOT NULL COMMENT '0:normal status,1:defense status',
  `log_created` datetime(6) NOT NULL COMMENT 'create datetime',
  `log_modified` datetime(6) NOT NULL COMMENT 'modify datetime',
  UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`),
  KEY `ix_log_created` (`log_created`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='AT transaction mode undo table';

4.修改seata/conf目录下的application.yaml文件，其余配置按照原先的配置即可，需要修改的地方主要是seata处

server:
  port: 7091 

spring:
  application:
    name: seata-server


logging:
  config: classpath:logback-spring.xml
  file:
    path: ${user.home}/logs/seata
  extend:
    logstash-appender:
      destination: 127.0.0.1:4560
    kafka-appender:
      bootstrap-servers: 127.0.0.1:9092
      topic: logback_to_logstash

console:
  user:
    username: seata
    password: seata

seata:
  config:
    type: nacos #使用nacos作为配置中心
    nacos:
      server-addr: http://localhost:8848 #启动可能会出现Client not connected,current status:STARTING,那就将地址换成http://192.168.72.130:8848
      namespace: public #命名空间配置
      group: DEFAULT_GROUP #分组信息配置
      username: nacos #如果开启了nacos的验证功能则需要配置
      password: nacos
      data-id: seataServer.properties #nacos中的配置文件名称
  registry:
    type: nacos #使用nacos作为注册中心
    nacos:
      application: seata-server
      server-addr: http://localhost:8848 #出现Client not connected,current status:STARTING就配上http
      group: DEFAULT_GROUP
      namespace: public
      cluster: seatatest #此处注意,这的值要和nacos中的配置文件service.vgroupMapping.my_test_tx_group的值一样
      username: nacos
      password: nacos
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

nacos添加配置文件

#此处需要注意,这里的配置需要在nacos中新建一个配置文件，就叫service.vgroupMapping.my_test_tx_group文件里面值就是seatatest和前面的配置registry.nacos.cluster的值是一样的
service.vgroupMapping.my_test_tx_group=seatatest

7.启动seata,进入seata/bin目录，执行 sh seata-server.sh,浏览器访问http://ip:7091/
