Kite学习历程的第三十二天

1. Seata的安装

1.1 Seata 的下载

注意如果你在官网进行下载的话会速度特别的慢，而已下到一般还出现错误，亲生经历，所以此处给大家一个网盘下载地址：
1.1版本：
链接: https://pan.baidu.com/s/1Z4YY0-VXlmrePrH-6CfS7Q 提取码: pnis
0.9版本：（我安装的版本，因为更新到1.0后config中不提供数据库语句）

1.2 修改配置文件

打开config文件夹

修改file.conf文件
修改内容我在下面进行了注解

metrics {enabled = falseregistry-type = "compact"# multi exporters use comma dividedexporter-list = "prometheus"exporter-prometheus-port = 9898
}support {## springspring {# auto proxy the DataSource beandatasource.autoproxy = false}
}

修改 registry.conf
type = “nacos” 为nacos
nacos中的serverAddr=“localhost:8848”

registry {# file 、nacos 、eureka、redis、zk、consul、etcd3、sofatype = "nacos"nacos {serverAddr = "localhost:8848"namespace = ""cluster = "default"}eureka {serviceUrl = "http://localhost:8761/eureka"application = "default"weight = "1"}redis {serverAddr = "localhost:6379"db = "0"}zk {cluster = "default"serverAddr = "127.0.0.1:2181"session.timeout = 6000connect.timeout = 2000}consul {cluster = "default"serverAddr = "127.0.0.1:8500"}etcd3 {cluster = "default"serverAddr = "http://localhost:2379"}sofa {serverAddr = "127.0.0.1:9603"application = "default"region = "DEFAULT_ZONE"datacenter = "DefaultDataCenter"cluster = "default"group = "SEATA_GROUP"addressWaitTime = "3000"}file {name = "file.conf"}
}config {# file、nacos 、apollo、zk、consul、etcd3type = "file"nacos {serverAddr = "localhost"namespace = ""}consul {serverAddr = "127.0.0.1:8500"}apollo {app.id = "seata-server"apollo.meta = "http://192.168.1.204:8801"}zk {serverAddr = "127.0.0.1:2181"session.timeout = 6000connect.timeout = 2000}etcd3 {serverAddr = "http://localhost:2379"}file {name = "file.conf"}
}

1.3 在MySQL中创建数据库seata

以及相关的表

sql执行的语句在config中的

2. 如果你的MySQL是8.0以上的进行seata的运行就会报连接数据库错误

原因：因为seata的lib文件中的mysql驱动为5.几的版本不能连接8.0
解决方案: 删除lib中原来的mysql连接，然后添加醒的mysql数据连接，我这里添加的是：

3. 运行

首相运行nacos
运行seata，点击bin中的

运行结果：
