Seata安装

一、下载

从Seata下载地址下载
https://github.com/seata/seata/releases

这里下载的是seata-server-1.5.2.tar.gz

解压：

tar -xvf seata-server-1.5.2.tar.gz

修改配置：conf/application.yml

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: seata
    password: seata

seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    # 配置中心地址
    nacos:
      server-addr: 127.0.0.1:8848
      # namespace:
      group: SEATA_GROUP
      username: nacos
      password: nacos
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      data-id: seata-server.yaml
  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    #preferred-networks: *.*.*.*
    nacos:
      application: seata-server
      server-addr: 127.0.0.1:8848
      group: SEATA_GROUP
      # 默认public
      # namespace:
      # 加入集群名称
      cluster: default
      username: nacos
      password: nacos
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
#  server:
#    service-port: 8091 #If not configured, the default is '${server.port} + 1000'
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017

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

二、MySQL配置

在MySQL8数据库中创建库表
安装步骤：https://blog.youkuaiyun.com/dreambyday/article/details/126022359

创建库、表、赋权

CREATE USER 'seata'@'%' IDENTIFIED BY 'seata';

create database IF NOT EXISTS seata;

GRANT ALL PRIVILEGES ON seata.* to 'seata'@'%'  with GRANT OPTION;

FLUSH PRIVILEGES;

在服务器seata/script/server/db/目录下找到mysql.sql脚本并执行，建立global_table，branch_table，lock_table，distributed_lock表

三、Nacos配置

nacos 里添加配置上面配置的

data-id: seata-server.yaml

group: SEATA_GROUP

修改数据库连接信息

  mode: db
  lock:
    mode: db
  session:

四、启动

启动
在bin目录下

sh seata-server.sh -p 8091 -h 127.0.0.1 -m db

查看启动日志，无报错即成功。

tail -200f 日志文件目录

访问服务
IP::7091/#/TransactionInfo
