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=mysql db.num=1 db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true db.user=root db.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-server store { ## 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
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持自学编程网。
