Seata 搭建 db模式
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.

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。
- 解压缩: seata-1.6.1.tar.gz
- 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
;

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

#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

server.enableParallelRequestHandle=false
#Metrics configuration, only for the server
metrics.enabled=false
metrics.registryType=compact
metrics.exporterList=prometheus
metrics.exporterPrometheusPort=9898
- 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
- 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
如下参考:
server:
port: 7091
spring:
application:
name: seata-server
logging:
config: classpath:logback-spring.xml
file:
path: ${user.home}/logs/seata
extend:
logstash-appender:
destination: 127.0.0.1:4560
kafka-appender:
bootstrap-servers: 127.0.0.1:9092
topic: logback_to_logstash
console:
user:
username: xxx
password: xxx
seata:
config:
type: nacos
nacos:
server-addr: 172.22.1.190:8848
group: DEFAULT_GROUP
username: xxx
password: xxx
context-path:
data-id: seataServer.properties
registry:
type: nacos
preferred-networks: 172.22.*
nacos:
application: seata-server
server-addr: xxx:8848
group: test
cluster: default
username: nacos
password: SOPQzj312
context-path:
store:
mode: db
db:
datasource: druid
db-type: mysql
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://xxx:3306/sxxc_seata?rewriteBatchedStatements=true
user: xxx
password: xxx
min-conn: 10
max-conn: 100
global-table: global_table
branch-table: branch_table
lock-table: lock_table
distributed-lock-table: distributed_lock
query-limit: 1000
max-wait: 5000
security:
secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
tokenValidityInMilliseconds: 1800000
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:
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
password: xxx
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:
type: nacos
nacos:
server-addr: 127.0.0.1:8848
group : "SEATA_GROUP"
namespace: "xxxxx"
username: "xxx"
password: "xxx"
5.1.3、 修改 appplication.yml seata.registry
seata:
registry:
type: nacos
nacos:
application: "seata-server"
serverAddr: 127.0.0.1:8848
group: "SEATA_GROUP"
namespace: "xxxxxx"
username: "xxxx"
password: "xxx"
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
- 执行sql创建数据表
- 使用脚本添加配置到nacos配置中心
- 修改application.yml文件,分别修改store、config、registry相关配置。
- 启动服务,成功登陆seata控制台。
- 查看nacos控制台,服务列表新增seata服务。
