Springcloud seata nacos環境搭建過程圖解
最近學習了一下seata,由於nacos現在也挺火,於是學習了seata註冊到nacos,然後整合springcloud
1.nacos配置(自行上官網下載)
將nacos/conf/nacos-mysql.sql匯入自己的資料庫
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.啟動nacos
windows直接雙擊startup.cmd
linux不要直接sh startup.sh 加入引數 -m standalone或者改startup.sh -m引數,linux指令碼預設叢集啟動,不改引數也不加啟動引數會報錯
啟動成功
4.下載seata,建議直接下載原始碼編譯
mvn -Prelease-all -DskipTests clean install -U
5.使用db模式匯入配置
上面是原始碼目錄,mysql.sql為seata庫必須的表,執行sql即可
將上面的config.txt檔案複製到seata目錄,nacos中的nacos-config.shnacos-config.py複製到seata的conf目錄
git 命令框執行 sh nacos-config.sh hostip 即可,位置為什麼這樣自己看下指令碼就知道了
配置都進來了,注意上面的紅框,如果你網上搜的指令碼匯入的,seata是1.0及之前的版本上面是對的,如果1.1及最新的原始碼改成vgroupMapping了,報錯參考另一篇部落格
5.修改seata配置
修改file.conf
service { #transaction service group mapping vgroupMapping.my_tx_group="default" #此處根據自己的情況修改 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的驅動,否則報錯 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" } }
然後將上面兩個配置檔案複製到你的springcloud模組中
6.啟動seata
如果之前在其他ip啟動過,將file_store/data下的檔案清掉,不然會報錯
7.springcloud程式碼
去https://gitee.com/code_fun/example.git 把demo.zip下載跑就可以了,前提是建好資料庫哦
demo.sql有表結構,undo_log表每個庫都要有
