Seata，一款开源的分布式事务解决方案，致力于提供高性能和简单易用的分布式事务服务。

Three roles in Seata Framework:

Transaction Coordinator(TC): Maintain status of global and branch transactions, drive the global commit or rollback.

Transaction Manager(TM): Define the scope of global transaction: begin a global transaction, commit or rollback a global transaction.

Resource Manager(RM): Manage resources that branch transactions working on, talk to TC for registering branch transactions and reporting status of branch transactions, and drive the branch transaction commit or rollback.

一、在Linux上安装seata

安装Seata，存储模式使用MySQL，服务发现和配置使用Nacos。

1.下载Seata

版本：v1.6.0

发布日期：Dec 17, 2022

下载地址：wget https://github.com/seata/seata/releases/download/v1.6.0/seata-server-1.6.0.tar.gz

下载包：seata-server-1.6.0.tar.gz

2.解压Seata

解压命令：tar -zxvf seata-server-1.6.0.tar.gz -C /opt/seata-1.6.0

解析：把seata-server-1.6.0.tar.gz解压到/opt/seata-1.6.0。在seata下的目录。bin目录是启动脚本。conf目录是配置文件。ext目录下是skywalking插件相关内容。lib目录是全量jar包。logs目录是日志包。script目录是脚本目录。target目录是seata-server.jar包。

3.初始化数据库脚本

本例存储模式使用MySQL数据库。

3.1创建数据库和用户

用户名/口令：hub_seata/12345678

数据库名称：hub_seatadb

登录控制台：mysql -u root -p

在MySQL命令行控制台执行脚本。

USE mysql;
CREATE DATABASE hub_seatadb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER hub_seata@'%' IDENTIFIED BY '12345678';
GRANT ALL ON hub_seatadb.* TO 'hub_seata'@'%' IDENTIFIED BY '12345678';
FLUSH PRIVILEGES;

3.2初始化seata数据库

脚本目录：/opt/seata-1.6.0/script/server/db/mysql.sql

初始化表：branch_table、distributed_lock、global_table、lock_table。

4.启动Nacos

启动脚本目录：/opt/nacos-2.1.1/bin

4.1启动Nacos

启动命令：sh startup.sh -m standalone

地址：http://127.0.0.1:18848/nacos

用户名/口令：nacos/nacos

4.2创建seata命名空间

命名空间名称：hub_seata

命名空间ID：142eba5f-a7b5-4a83-85bb-663c582c8ef1

5.配置seata

在/opt/seata-1.6.0/conf目录下，application.example.yml是配置文件的模板，包含全量配置。application.yml是应用启动时加载配置，根据实际情况按需从application.example.yml中拷贝添加就行

5.1修改application.yml配置

修改文件：/opt/seata-1.6.0/conf/application.yml

修改内容：

server:
  port: 7091
spring:
  application:
    name: seata-server
logging:
  config: classpath:logback-spring.xml
  file:
    path: ${user.home}/logs/seata

      cluster: default

    mode: db
    db:

      user: hub_seata

    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

5.2在Nacos新建seataServer.properties

5.2.1页面配置

在Nacos页面中，选择

命名空间：hub_seata。命名空间ID：142eba5f-a7b5-4a83-85bb-663c582c8ef1。创建配置seataServer.properties。

Data ID：seataServer.properties。

Group：SEATA_GROUP

配置格式：Properties

配置内容：从/opt/seata-1.6.0/script/config-center\config.txt文件中拷贝需求的配置。

本例从config.txt摘取的配置修改过的配置。

service.vgroupMapping.hub_tx_group=default
store.mode=db
store.lock.mode=db
store.session.mode=db
store.publicKey=123456
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://192.168.19.203:3306/hub_seatadb?useUnicode=true&rewriteBatchedStatements=true
store.db.user=hub_seata
store.db.password=12345678

解析：config.txt配置内容在源码包../seata-1.6.0/config/seata-config-core/src/main/resources/config.txt和安装包/opt/seata-1.6.0/script/config-center/config.txt两处位置都可以找到。

5.2.2配置生效

在Nacos中配置已经生效。

6启动seata

6.1启动seata

操作目录：/opt/seata-1.6.0/bin

启动命令：sh seata-server.sh

6.2查看seata日志

日志：/opt/seata-1.6.0/logs/start.out

命令：tail -f -n 300 /opt/seata-1.6.0/logs/start.out

6.3查看seata已注册

在Nacos已经注册了seata-server服务。

7基于普通用户使用seata

在启动seata时，不使用root用户直接启动，建议使用普通用户。

改变安装目录赋权给一个普通用户就可以。

7.1创建普通用户操作

创建用户命令：useradd learn

修改密码命令：passwd

解析：在执行passwd时，提示输入密码。可以查看用户信息：cat /etc/passwd。

7.2普通用户信息

用户名称/口令：learn/12345678

7.3把seata的安装目录赋权给普通用户

命令：chown -R learn:learn /opt/seata-1.6.0

7.4启动seata

切换用户：su learn

操作目录：/opt/seata-1.6.0/bin

启动命令：sh seata-server.sh

8.使用nacos-config.sh脚本加载配置

使用nacos-config.sh脚本加载config.txt配置到nacos。

脚本目录：/opt/seata-1.6.0/script/config-center/nacos

命令：sh nacos-config.sh -h 192.168.19.203 -p 18848 -g SEATA_GROUP -t 142eba5f-a7b5-4a83-85bb-663c582c8ef1 -u nacos -w nacos

解析：本例没有使用这种方式。

二、在Windows上安装seata

安装Seata，存储模式使用MySQL，服务发现和配置使用Nacos。

1.下载Seata

版本：v1.6.0

发布日期：Dec 17, 2022

下载地址：https://github.com/seata/seata/releases/download/v1.6.0/seata-server-1.6.0.zip

下载包：seata-server-1.6.0.zip

2.解压Seata

seata-server-1.6.0.zip包解压到D:\dev\hub\ali\seata-1.6.0。

在seata-1.6.0下的目录。bin目录是启动脚本。conf目录是配置文件。ext目录下是skywalking插件相关内容。lib目录是全量jar包。logs目录是日志包。script目录是脚本目录。target目录是seata-server.jar包。

3.初始化数据库脚本

本例存储模式使用MySQL数据库。

3.1创建数据库和用户

用户名/口令：hub_seata/12345678

数据库名称：hub_seatadb

FLUSH PRIVILEGES;

3.2初始化seata数据库

脚本目录：seata\script\server\db\mysql.sql

初始化表：branch_table、distributed_lock、global_table、lock_table。

4.启动Nacos

启动脚本目录：D:\dev\hub\ali\nacos-2.1.1\nacos\bin

4.1启动Nacos

启动命令：sh startup.sh -m standalone

地址：http://192.168.19.203:18848/nacos

用户名/口令：nacos/nacos

4.2创建seata命名空间

命名空间名称：hub_seata

命名空间ID：142eba5f-a7b5-4a83-85bb-663c582c8ef1

5.配置seata

在..\seata\conf目录下，application.example.yml是配置文件的模板，包含全量配置。application.yml是应用启动时加载配置，根据实际情况按需从application.example.yml中拷贝添加就行
