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-安装包:https://github.com/alibaba/nacos/releases
seata官方-安装包:https://github.com/seata/seata/releases
seata官网:http://seata.io/zh-cn/
-自己喜欢的版本,我-的是1.4.0
第二步:创建数据库
-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-:两个文件config.txt、nacos-config.sh 这里我就不给-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:
