docker部署seata1.6.0

Seata 是阿里巴巴开源的分布式事务中间件，解决微服务场景下面临的分布式事务问题。需要先搭建seata服务端然后与springcloud的集成以实现分布式事务控制的过程，项目中只需要在远程调用APi服务的方法上使用注解 @GlobalTransactional，就能实现跨模块事务回滚。

一、安装seata1.6.0

docker pull seataio/seata-server:1.6.0
# 启动容器
docker run -d --name seata-server -p 8091:8091 -p 7091:7091  seataio/seata-server:1.6.0
# 拷贝文件到宿主机目录/opt/seata/seata-server（这个目录需要先手动创建）
cd /opt
mkdir seata
cd /opt/seata
mkdir seata-server
docker cp seata-server:/seata-server/resources  /opt/seata/seata-server/
# 停止并删除容器
docker stop seata-server
docker rm seata-server
# 修改/opt/seata/seata-server/resources目录下的文件application.yml
# 重新启动容器
docker run -i -t -d --restart always --name seata-server \
-p 7091:7091 -p 8091:8091  \
-e SEATA_IP=192.168.124.11 \
-e SEATA_PORT=8091 \
-e TZ=Asia/Shanghai  \
-v /opt/seata/seata-server/resources:/seata-server/resources \
-v /etc/localtime:/etc/localtime \
seataio/seata-server:1.6.0

# -e SEATA_IP=[公网IP] 这个ip必须是公网ip，否则会访问失败

二、修改配置文件application.yml

修改控制台登录账号密码

console:
  user:
    username: seata11
    password: 123456

修改type=nacos
修改nacos连接的账号密码
修改数据库连接

三、nacos中创建配置文件seataServer.properties

在这里插入图片描述

seataServer.properties
修改service.vgroupMapping.mygroup=default


#For details about configuration items, see https://seata.io/zh-cn/docs/user/configurations.html

service.vgroupMapping.mygroup=default
#If you use a registry, you can ignore it
service.default.grouplist=192.168.124.11:8091

#For TCC transaction mode
tcc.fence.logTableName=tcc_fence_log
tcc.fence.cleanPeriod=1h

#Log rule configuration, for client and server
log.exceptionRate=100

#Transaction storage configuration, only for the server. The file, db, and redis configuration values are optional.
# 默认为file，一定要改为db，我们自己的服务启动会连接不到seata
store.mode=db
store.lock.mode=db
store.session.mode=db
#Used for password encryption

#These configurations are required if the `store mode` is `db`. If `store.mode,store.lock.mode,store.session.mode` are not equal to `db`, you can remove the configuration block.
# 修改mysql的配置

# 数据存储方式，db代表数据库
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://192.168.124.11:3306/seata_db?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false

server.enableParallelRequestHandle=false

#Metrics configuration, only for the server
metrics.enabled=false
metrics.registryType=compact
metrics.exporterList=prometheus
metrics.exporterPrometheusPort=9898

四、nacos中配置service.vgroupMapping.mygroup

在这里插入图片描述

五、项目中配置seata

bootstrap.yml中配置


seata:
  application-id: ${spring.application.name}
  #数据源代理模式使用AT模式(可以不用配置，seata默认使用AT模式)
  data-source-proxy-mode: AT
  tx-service-group: mygroup # 事务分组名称，要和服务端对应
  #事务群组（可以每个应用独立取名，也可以使用相同的名字），
  #要与服务端nacos配置seataServer.properties中service.vgroupMapping.mygroup=default中存在,
  #此处的mygroup名字可以自定义,与 tx-service-group: mygroup中的mygroup保持一致
  service:
    vgroup-mapping:
      mygroup: default
  enabled: false

  registry:
    type: nacos
    nacos:
      username: root
      password: 123456
      namespace: @nacos.config.namespace@
      server-addr: @nacos.server-addr@
      group: SEATA_GROUP
      #seata服务名
      application: seata-server

  config:
    type: nacos
    nacos:
      username: root
      password: 123456
      namespace: @nacos.config.namespace@
      server-addr: @nacos.server-addr@
      group: SEATA_GROUP
