    fi

4.修改config.txt配置文件  
修改config.txt

注意：大多数小伙伴只需要修改以下几个参数，其他参数可暂时不改

#tx_group：自定义名字，很重要，与项目配置文件的tx-service-group一一对应
    service.vgroupMapping.tx_group=default
    #seata的ip+端口
    service.default.grouplist=192.168.2.64:8091
    
    # 修改存储模式为数据库存储
    store.mode=db
    # 指定数据库为mysql，其他数据库类型根据自身情况修改
    store.db.dbType=mysql
    # 指定引擎，mysql8以下为com.mysql.jdbc.Driver，mysql8为com.mysql.cj.jdbc.Driver
    store.db.driverClassName=com.mysql.cj.jdbc.Driver
    store.db.url=jdbc:mysql://{ ip}:3306/{ db_name}?useUnicode=true
    store.db.user={ db_user}
    store.db.password={ db_password}

5.将修改好的config.txt配置添加到nacos配置中心

将config.txt文件放到nacos-config.sh文件所在目录的上一级目录（nacos-config.sh不作任何修改）
    
    sh nacos-config.sh -h { nacos服务的ip} -u { nacos用户名} -w { nacos密码}

6.编写registry.conf  
docker-compose.yml配置文件需要

这个文件的目的就是配置seata-server服务从nacos上读取第3步上传上去的配置，并且把自己注册到nacos的服务列表中去

registry { 
      # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
      # 指定注册中心为nacos
      type = "nacos"
    
      nacos { 
        serverAddr = "{nacos服务的ip}:{nacos服务的端口}"
        namespace = ""
        cluster = "default"
        username="{username}"
        password="{password}"
      }
    }
    
    config { 
      # file、nacos 、apollo、zk、consul、etcd3
      type = "nacos"
    
      nacos { 
        serverAddr = "{nacos服务的ip}:{nacos服务的端口}"
        namespace = ""
        username="{username}"
        password="{password}"
      }
    }

7.准备初始化数据库  
创建第三步配置的数据库，执行下列sql

-- the table to store GlobalSession data
    drop table if exists `global_table`;
    create table `global_table` (
      `xid` varchar(128)  not null,
      `transaction_id` bigint,
      `status` tinyint not null,
      `application_id` varchar(32),
      `transaction_service_group` varchar(32),
      `transaction_name` varchar(128),
      `timeout` int,
      `begin_time` bigint,
      `application_data` varchar(2000),
      `gmt_create` datetime,
      `gmt_modified` datetime,
      primary key (`xid`),
      key `idx_gmt_modified_status` (`gmt_modified`, `status`),
      key `idx_transaction_id` (`transaction_id`)
    );
    
    -- the table to store BranchSession data
    drop table if exists `branch_table`;
    create table `branch_table` (
      `branch_id` bigint not null,
      `xid` varchar(128) not null,
      `transaction_id` bigint ,
      `resource_group_id` varchar(32),
      `resource_id` varchar(256) ,
      `lock_key` varchar(128) ,
      `branch_type` varchar(8) ,
      `status` tinyint,
      `client_id` varchar(64),
      `application_data` varchar(2000),
      `gmt_create` datetime,
      `gmt_modified` datetime,
      primary key (`branch_id`),
      key `idx_xid` (`xid`)
    );
    
    -- the table to store lock data
    drop table if exists `lock_table`;
    create table `lock_table` (
      `row_key` varchar(128) not null,
      `xid` varchar(96),
      `transaction_id` long ,
      `branch_id` long,
      `resource_id` varchar(256) ,
      `table_name` varchar(32) ,
      `pk` varchar(36) ,
      `gmt_create` datetime ,
      `gmt_modified` datetime,
      primary key(`row_key`)
    );

8.启动seata-server服务

docker-compose up -d

9、查看nacos服务里是否启动成功
