创建Seata的数据库及表，地址：https://github.com/seata/seata/tree/develop/script/server

根据数据类型复制相应的sql，进行建库建表

修改conf目录下的file.conf 配置文件
路径：/usr/local/seata-server-1.4.2/conf

修改前：
在这里插入图片描述
修改后：

mysql5.7 使用 com.mysql.jdbc.Driver

Mysql8.0 使用 com.mysql.cj.jdbc.Driver

MySQL5.7：

driverClassName = "com.mysql.jdbc.Driver"
   url = "jdbc:mysql://127.0.0.1:3306/travel-seata?useUnicode=true&rewriteBatchedStatements=true&serverTimezone=GMT"

MySQL5.8：

    driverClassName = "com.mysql.cj.jdbc.Driver"
    ## if using mysql to store the data, recommend add rewriteBatchedStatements=true in jdbc connection param
    url = "jdbc:mysql://127.0.0.1:3306/travel-seata?useUnicode=true&rewriteBatchedStatements=true&serverTimezone=GMT"

数据库连接地址:127.0.0.1:3306/travel-seata 根据自己情况修改

Nacos创建命名空间
在nacos创建一个命名空间

创建之后会生成一个命名空间ID,后面的配置会用到，此处我的命名空间ID=9901bfad-77eb-4de9-8396-13338b1f378d
修改conf目录下的 registry.conf配置文件

在这里插入图片描述
修改内容：

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"   #修改为nacos

  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"   #自己的nacos地址
    group = "SEATA_GROUP"
    
    #上一步新建命名空间时生产的命名空间ID
    namespace = "9901bfad-77eb-4de9-8396-13338b1f378d" 

    cluster = "default"

	#naocs登陆的用户名密码
    username = "nacos"
    password = "nacos"
  }
  eureka {

    group = "SEATA_GROUP"
    addressWaitTime = "3000"
  }
  file {
    name = "file.conf"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos" #改为nacos


# nacos的地址、命名空间ID、naos登陆用户名密码
  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = "9901bfad-77eb-4de9-8396-13338b1f378d"

    aclToken = ""
  }
  apollo {
    appId = "seata-server"
    ## apolloConfigService will cover apolloMeta
    apolloMeta = "http://192.168.1.204:8801"
    apolloConfigService = "http://192.168.1.204:8080"
    namespace = "application"
    apolloAccesskeySecret = ""
    cluster = "seata"
  }
  zk {
    serverAddr = "127.0.0.1:2181"
    sessionTimeout = 6000
    connectTimeout = 2000
    username = ""
    password = ""
    nodePath = "/seata/seata.properties"
  }
  etcd3 {
    serverAddr = "http://localhost:2379"
  }
  file {
    name = "file.conf"
  }
}

MySQL驱动位置更改

在 /seata-server-1.4.2/lib/jdbc 下有MySQL的驱动，需要将相关的驱动移动到**/seata-server-1.4.2/lib/**下

在这里插入图片描述

根据自己数据库的版本移动相应的驱动，我的是MySQL8

//将驱动复制到上一级目录（seata的lib目录）
cp mysql-connector-java-8.0.19.jar  ../

检查seata的lib目录下是否有驱动
在这里插入图片描述

nacos创建seata的配置文件 seataServer.properties

在naocs的配置列表的seata命名空间创建seataServer.properties 配置文件
在这里插入图片描述
注意配置文件的分组和名字必须和配置文件中保持一致

在这里插入图片描述

seataServer.properties文件内容如下：

文件内容获取地址：

https://github.com/apache/incubator-seata/blob/develop/script/config-center/config.txt

naocs配置文件生成
在源码目录中： https://github.com/seata/seata/tree/develop/script/config-center 找到nacos-config.sh 并下载下来，
运行 nacos-config.sh脚本将配置文件推送到nacos.(运行时需要输入nacos的相关参数，或者可以直接在脚本中修改)

或者运行时指定参数：

sh nacos-config.sh -h localhost -p 8848 -g SEATA_GROUP -t 命名空间ID

在这里插入图片描述
运行后nacos中会多出一些配置文件

运行启动脚本

bin目录下执行

 sh seata-server.sh

在这里插入图片描述

脚本文件说明：

client：


https://github.com/seata/seata/tree/develop/script/client

存放用于客户端的配置和SQL

- at: AT模式下的 undo_log 建表语句
- conf: 客户端的配置文件
- saga: SAGA 模式下所需表的建表语句
- spring: SpringBoot 应用支持的配置文件

server

https://github.com/seata/seata/tree/develop/script/server

存放server侧所需SQL和部署脚本

- db: server 侧的保存模式为 db 时所需表的建表语句
- docker-compose: server 侧通过 docker-compose 部署的脚本
- helm: server 侧通过 Helm 部署的脚本
- kubernetes: server 侧通过 Kubernetes 部署的脚本

config-center

https://github.com/seata/seata/tree/develop/script/config-center
用于存放各种配置中心的初始化脚本，执行时都会读取 config.txt配置文件，并写入配置中心

- nacos: 用于向 Nacos 中添加配置
- zk: 用于向 Zookeeper 中添加配置，脚本依赖 Zookeeper 的相关脚本，需要手动下载；ZooKeeper相关的配置可以写在 zk-params.txt 中，也可以在执行的时候输入
- apollo: 向 Apollo 中添加配置，Apollo 的地址端口等可以写在 apollo-params.txt，也可以在执行的时候输入
- etcd3: 用于向 Etcd3 中添加配置
- consul: 用于向 consul 中添加配置
