在win10系统下,如何配置Spring Cloud alibaba Seata以及出现问题时怎么解决

在win10系统下,如何配置Spring Cloud alibaba Seata以及出现问题时怎么解决

实战开始

先看报错问题：

config.txt: No such file or directory

=========================================================================

Complete initialization parameters, total-count:0 , failure-count:0

=========================================================================

Init nacos config finished, please start seata-server.

去nacos中，配置文件一个也没有加到到自己的匿名空间里。慢慢听我讲

客官先别急，喝杯茶。

分布式事务seata要与nacos服务注册与发现紧密使用。

nacos官方下载安装包：https://github.com/alibaba/nacos/releases

seata官方下载安装包：https://github.com/seata/seata/releases

seata官网：http://seata.io/zh-cn/

下载自己喜欢的版本，我下载的是1.4.0

第二步：创建数据库

下载维护seata事务信息的mysql.sql

-- the table to store GlobalSession data

use seata;

drop table if exists `seata.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`)

);

还需要下载：两个文件config.txt、nacos-config.sh 这里我就不给下载链接了，直接复制就好

nacos-config.sh 这个文件不需要改动

看我文件路径：

一定记得把config.txt 放在 seata目录的上级目录

解决问题：

是因为没有找到那config.txt文件（注意文件路径。nacos-config.sh这个文件的上级目录中即可）

双击：nacos-config.sh这个文件

或者在git执行命令：

sh nacos-config.sh -h 192.168.0.104 -p 8848 -g SEATA_GROUP -t 9704bb45-3e8b-479d-b491-f0f77765e2df

再去查看nacos中的配置列表：

启动seata服务

修改两个文件：

registry.conf 注意两个地方

启动seata服务：

查看nacos属于自己的匿名空间：

服务列表：
