01-创建application.yaml文件

代码语言：txt复制
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: admin
    password: admin
seata:
  config:
     support: nacos 、 consul 、 apollo 、 zk  、 etcd3
    type: nacos
    nacos:
      server-addr: http:// 127.0.0.1:8848
      namespace:
      group: SEATA_GROUP
      username:
      password:
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      data-id: seataServer.properties
  registry:
     support: nacos 、 eureka 、 redis 、 zk  、 consul 、 etcd3 、 sofa
    type: nacos
    preferred-networks: 30.240.*
    nacos:
      application: seata-server
      server-addr: http:// 127.0.0.1:8848
      group: SEATA_GROUP
      namespace:
      cluster: default
      username:
      password:
      ##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

02-在application.yml旁边建立Dockerfile文件

代码语言：txt复制
FROM seataio/seata-server:1.5.0
ADD application.yml  /seata-server/resources/application.yml

03-执行docker命令构建镜像

代码语言：txt复制
 docker build -t seata-server:1.5.0 .

04-启动nacos服务

代码语言：txt复制
docker run --name docker-quick -e MODE=standalone -p 8848:8848 -p 9848:9848 -d nacos/nacos-server:v2.0.4

05-使用数据库方式启动nacos(上下两种任选1种)

代码语言：txt复制
docker run -d -p 8848:8848 -p 9848:9848 -e PREFER_HOST_MODE=hostname  -e MODE=standalone -e SPRING_DATASOURCE_PLATFORM=mysql -e MYSQL_SERVICE_HOST=127.0.0.1 -e MYSQL_SERVICE_PORT=3306 -e MYSQL_SERVICE_USER=root -e MYSQL_SERVICE_PASSWORD=root -e MYSQL_SERVICE_DB_NAME=nacos_db --name nacos-standalone nacos/nacos-server

06-在配置列表中添加seata数据库配置

代码语言：java复制
 存储模式
store.mode=db

store.db.datasource=druid
store.db.dbType=mysql
 需要根据mysql的版本调整driverClassName
 mysql8及以上版本对应的driver：com.mysql.cj.jdbc.Driver
 mysql8以下版本的driver：com.mysql.jdbc.Driver
store.db.driverClassName=com.mysql.jdbc.Driver
 注意根据生产实际情况调整参数host和port
store.db.url=jdbc:mysql://127.0.0.1:3306/seata_db?rewriteBatchedStatements=true&useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false
 数据库用户名
store.db.user=root
 用户名密码
store.db.password=root
 微服务里配置与这里一致
service.vgroupMapping.default_tx_group=default

07-在数据库添加数据表

代码语言：txt复制
---- The script used when storeMode is 'db' ----
-- the table to store GlobalSession data --
CREATE TABLE IF NOT EXISTS `global_table`

    PRIMARY KEY (`row_key`),
    KEY `idx_status` (`status`),
    KEY `idx_branch_id` (`branch_id`),
    KEY `idx_xid_and_branch_id` (`xid` , `branch_id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8mb4;

CREATE TABLE IF NOT EXISTS `distributed_lock`
(
    `lock_key`       CHAR(20) NOT NULL,
    `lock_value`     VARCHAR(20) NOT NULL,
    `expire`         BIGINT,
    primary key (`lock_key`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8mb4;

INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('AsyncCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryCommitting', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('RetryRollbacking', ' ', 0);
INSERT INTO `distributed_lock` (lock_key, lock_value, expire) VALUES ('TxTimeoutCheck', ' ', 0);
