Seata1.5.2安装配置(nacos)+部署

news2024/11/20 9:40:01

一、seata服务端下载，下载方式介绍两种入口，如下：

1. seata官网 (http://seata.io/zh-cn/blog/download.html) 下载中心

找到对应版本，下载 binary 即可。下载包名为：seata-server-1.5.2.zip

2. github上下载 Releases · seata/seata · GitHub

找到对应的1.5.2版本，每个版本下都有一个缩放的Assets，点击下载即可。

二、解压、修改配置(配置nacos)

1. 解压zip，linux解压后目录一致

2.seata配置nacos，进入 conf目录下 cd \seata-server-1.5.2\seata\conf ，修改 application.yml 配置文件内容。内容如下，直接使用即可。

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
    nacos:
      server-addr: xx.xx.xx.110:8848
      namespace: seata-namespace-id
      group: SEATA_GROUP
      username: nacos
      password: nacos
      data-id: seataServer.properties

  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    nacos:
      application: seata-server
      server-addr: xx.xx.xx.110:8848
      group: SEATA_GROUP
      namespace: seata-namespace-id
      cluster: default
      username: nacos
      password: nacos

#  store:
    # support: file 、 db 、 redis
 #   mode: file
#  server:
#    service-port: 8091 #If not configured, the default is '${server.port} + 1000'
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

注意其中需要修改的几个值：

3.nacos中创建命名空间，id为上图中的 seata-namespace-id ，名称为 seata

4. nacos配置列表中新增配置，Data id 为上图中的 seataServer.properties， group 为：SEATA_GROUP. 如下：以下内容可以直接复制使用。

store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://xx.xx.x.xxx:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
store.db.password=xxxxxx
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.distributedLockTable=distributed_lock
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

service.vgroupMapping.default_tx_group=default

三、配置数据库(mysql)

1. 上面2.4中配置了mysql数据库地址，从下载包中找到对应sql.

cd \seata-server-1.5.2\seata\script\server\db

该目录下找到对应mysql.sql文件，在 seata数据库中执行即可。

其中某些字段根据程序已做了部分优化，可以直接使用。

四、启动seata

1. 进入启动目录，输入如下命令启动即可。

1. 进入bin目录(这里只提示路径)
cd  seata-server-1.5.2\seata\bin;

2. 执行服务
sh seata-server.sh -h xx.xx.x.xxx -p 8091


注意上面的 -h :指该服务器ip，不指定的话，不然注册到nacos的会是不想要的本地ip(127.xx.xx.xx)
