最近学习了一下seata，由于nacos现在也挺火，于是学习了seata注册到nacos，然后集成springcloud

1.nacos配置（自行上官网下载）

将nacos/conf/nacos-mysql.sql导入自己的数据库

2.配置修改nacos/conf/application.properties

spring.datasource.platform=mysqldb.num=1db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=truedb.user=rootdb.password=123456

3.启动nacos

windows直接双击startup.cmd

linux不要直接sh startup.sh 加入参数 -m standalone或者改startup.sh -m参数，linux脚本默认集群启动，不改参数也不加启动参数会报错

启动成功

4.下载seata，建议直接下载源码编译

mvn -Prelease-all -DskipTests clean install -U

5.使用db模式导入配置

上面是源码目录，mysql.sql为seata库必须的表，执行sql即可

将上面的config.txt文件复制到seata目录，nacos中的nacos-config.shnacos-config.py复制到seata的conf目录

git 命令框执行 sh nacos-config.sh hostip 即可，位置为什么这样自己看下脚本就知道了

配置都进来了，注意上面的红框，如果你网上搜的脚本导入的，seata是1.0及之前的版本上面是对的，如果1.1及最新的源码改成vgroupMapping了，报错参考另一篇博客

5.修改seata配置

修改file.conf

service { #transaction service group mapping vgroupMapping.my_tx_group="default" #此处根据自己的情况修改 default.grouplist="127.0.0.1:8091" disableGlobalTransaction=false}## transaction log store, only used in seata-serverstore { ## store mode: file、db mode = "db" ## file store property file { ## store location dir dir = "sessionStore" # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions maxBranchSessionSize = 16384 # globe session size , if exceeded throws exceptions maxGlobalSessionSize = 512 # file buffer size , if exceeded allocate new buffer fileWriteBufferCacheSize = 16384 # when recover batch read size sessionReloadReadSize = 100 # async, sync flushDiskMode = async } ## database store property db { ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc. datasource = "druid" ## mysql/oracle/h2/oceanbase etc. dbType = "mysql" driverClassName = "com.mysql.jdbc.Driver" #不要用mysql8的驱动，否则报错 url = "jdbc:mysql://127.0.0.1:3306/seata" user = "root" password = "123456" minConn = 1 maxConn = 10 globalTable = "global_table" branchTable = "branch_table" lockTable = "lock_table" queryLimit = 100 }}

registry.conf

registry { # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa type = "nacos" nacos { serverAddr = "localhost:8848" namespace = "" cluster = "default" }}config { # file、nacos 、apollo、zk、consul、etcd3 type = "nacos" nacos { serverAddr = "localhost" namespace = "" group = "SEATA_GROUP" }}

然后将上面两个配置文件复制到你的springcloud模块中

6.启动seata

如果之前在其他ip启动过，将file_store/data下的文件清掉，不然会报错

7.springcloud代码

去https://gitee.com/code_fun/example.git 把demo.zip下载跑就可以了，前提是建好数据库哦

demo.sql有表结构，undo_log表每个库都要有
