版本 V1.6.1

一、 简介

Server端存储模式（store.mode）现有file、db、redis三种（后续将引入raft,mongodb），file模式无需改动，直接启动即可，下面专门讲下db和redis启动步骤。
注： file模式为单机模式，全局事务会话信息内存中读写并持久化本地文件root.data，性能较高;

db模式为高可用模式，全局事务会话信息通过db共享，相应性能差些;（推荐）

redis模式Seata-Server 1.3及以上版本支持,性能较高,存在事务信息丢失风险,请提前配置合适当前场景的redis持久化配置.

二、下载

1、官网 https://seata.io/zh-cn/
2、参考文档：https://seata.io/zh-cn/blog/seata-quick-start.html
3、部署指南：https://seata.io/zh-cn/docs/ops/deploy-guide-beginner.html

三、建表（仅db）

全局事务会话信息由3块内容构成，全局事务–>分支事务–>全局锁，对应表global_table、branch_table、lock_table
当前版本支持 3大数据库：mysql、postgresql 、oracle。

1. 解压缩： seata-1.6.1.tar.gz
2. mysql初始化脚本：seata/script/server/db/mysql.sql

DROP DATABASE IF EXISTS `sxxc_seata`;

CREATE DATABASE  `sxxc_seata` DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

USE `sxxc_seata`;
-- -------------------------------- The script used when storeMode is 'db' --------------------------------
-- the table to store GlobalSession data
CREATE TABLE IF NOT EXISTS `global_table`

  DEFAULT CHARSET = utf8mb4;

-- the table to store lock data
CREATE TABLE IF NOT EXISTS `lock_table`
(
    `row_key`        VARCHAR(128) NOT NULL,
    `xid`            VARCHAR(128),

    `lock_key`       CHAR(20) NOT NULL,
    `lock_value`     VARCHAR(20) NOT NULL,
    `expire`         BIGINT,
    primary key (`lock_key`)
) ENGINE = InnoDB

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);

四、配置 seata server 参数

4.1、V1.4.2之前方式

1. 修改config.txt
config.txt位置： seata/seata/script/config-center/config.txt

#Log rule configuration, for client and server
log.exceptionRate=100

#Transaction storage configuration, only for the server. The file, db, and redis configuration values are optional.
store.mode=db
store.lock.mode=db
store.session.mode=db
#Used for password encryption
store.publicKey=""

#These configurations are required if the `store mode` is `db`. If `store.mode,store.lock.mode,store.session.mode` are not equal to `db`, you can remove the configuration block.
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://172.22.2.187:3306/sxxc_seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root

server.enableParallelRequestHandle=false

#Metrics configuration, only for the server
metrics.enabled=false
metrics.registryType=compact
metrics.exporterList=prometheus
metrics.exporterPrometheusPort=9898

3. 初始化到nacos脚本

进入目录： cd ./seata/script/config-center

修改config.txt： 具体参考 ”修改config.txt“

sh nacos-config.sh -h 172.22.1.190 -p 8848 -g SEATA_GROUP -t d229c141-52de-4e60-bd4f-216391283c58 -u nacos -w SOPQzj312#!40Cc

-h – nacos ip
-p – nacos 端口
-g – seata-server配置文件 分组名
-t – seata-server配置文件 命名空间ID，当然在此之前需要现在nacos上新建命名空间并记录下命名空间ID
-u – nacos账号
-w – nacos密码

4.2、V1.4.2 之后推荐方式(seataServer.properties)

Seata从v1.4.2版本开始，支持从一个Nacos dataId配置项中获取所有配置信息。所以，在nacos配置中心中新建配置，dataId为 seataServer.properties配置项

1. 在nacos中 添加dataID：seataServer.properties文件，具体内容还是config.txt中的配置
   
   

五、配置Server

5.1、 修改 appplication.yml

cd ./seata/conf/application.yml

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

5.1.1、 修改 appplication.yml seata.store （db）

seata:
  store:
    # support: file 、 db 、 redis
    mode: db
    db:
      datasource: druid
      db-type: mysql
      driver-class-name: com.mysql.jdbc.Driver
      url: jdbc:mysql://xxxxx:3306/seata?rewriteBatchedStatements=true
      user: xxxx # mysql的用户名
      password: xxx #mysql的密码
      min-conn: 5
      max-conn: 100
      global-table: global_table
      branch-table: branch_table
      lock-table: lock_table
      distributed-lock-table: distributed_lock
      query-limit: 100
      max-wait: 5000

5.1.2、 修改 appplication.yml seata.config

seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      group : "SEATA_GROUP"
      namespace: "xxxxx"
      username: "xxx" # nacos的用户名
      password: "xxx"  # nacos的密码

5.1.3、 修改 appplication.yml seata.registry

seata:
  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    nacos:
      application: "seata-server"
      serverAddr: 127.0.0.1:8848
      group: "SEATA_GROUP"
      namespace: "xxxxxx"
      username: "xxxx" # nacos的用户名
      password: "xxx" # nacos的密码

5.2、启动Server

进入目录 cd ./seata/bin

sh seata-server.sh -h 172.22.1.190 -p 8091 -m db

5.3、查看nacos控台台

5.4、访问seata控制台

http://xxx:7091/

六、总结

seata安装版本是1.6.1，版本不同，安装流程也可能不同，这里的版本需要保持一致

1. 执行sql创建数据表
2. 使用脚本添加配置到nacos配置中心
3. 修改application.yml文件，分别修改store、config、registry相关配置。
4. 启动服务，成功登陆seata控制台。
5. 查看nacos控制台，服务列表新增seata服务。
