最近學習了一下seata，由於nacos現在也挺火，於是學習了seata注冊到nacos，然后集成springcloud
1.nacos配置（自行上官網下載）
將nacos/conf/nacos-mysql.sql導入自己的數據庫
2.配置修改nacos/conf/application.properties
1 spring.datasource.platform=mysql 2 db.num=1 3 db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true 4 db.user=root 5 db.password=123456
3.啟動nacos
windows直接雙擊startup.cmd
linux不要直接sh startup.sh 加入參數 -m standalone或者改startup.sh -m參數，linux腳本默認集群啟動，不改參數也不加啟動參數會報錯
啟動成功
4.下載seata，建議直接下載源碼編譯
mvn -Prelease-all -DskipTests clean install -U
5.使用db模式導入配置
上面是源碼目錄，mysql.sql為seata庫必須的表，執行sql即可
將上面的config.txt文件復制到seata目錄，nacos中的nacos-config.sh nacos-config.py復制到seata的conf目錄
git 命令框執行 sh nacos-config.sh hostip 即可，位置為什么這樣自己看下腳本就知道了
配置都進來了，注意上面的紅框，如果你網上搜的腳本導入的，seata是1.0及之前的版本上面是對的，如果1.1及最新的源碼改成vgroupMapping了，報錯參考另一篇博客
5.修改seata配置
修改file.conf
1 service { 2 #transaction service group mapping 3 vgroupMapping.my_tx_group="default" #此處根據自己的情況修改 4 default.grouplist="127.0.0.1:8091" 5 disableGlobalTransaction=false 6 } 7 ## transaction log store, only used in seata-server 8 store { 9 ## store mode: file、db 10 mode = "db" 11 12 ## file store property 13 file { 14 ## store location dir 15 dir = "sessionStore" 16 # branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions 17 maxBranchSessionSize = 16384 18 # globe session size , if exceeded throws exceptions 19 maxGlobalSessionSize = 512 20 # file buffer size , if exceeded allocate new buffer 21 fileWriteBufferCacheSize = 16384 22 # when recover batch read size 23 sessionReloadReadSize = 100 24 # async, sync 25 flushDiskMode = async 26 } 27 28 ## database store property 29 db { 30 ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc. 31 datasource = "druid" 32 ## mysql/oracle/h2/oceanbase etc. 33 dbType = "mysql" 34 driverClassName = "com.mysql.jdbc.Driver" #不要用mysql8的驅動，否則報錯 35 url = "jdbc:mysql://127.0.0.1:3306/seata" 36 user = "root" 37 password = "123456" 38 minConn = 1 39 maxConn = 10 40 globalTable = "global_table" 41 branchTable = "branch_table" 42 lockTable = "lock_table" 43 queryLimit = 100 44 } 45 }
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" } }
然后將上面兩個配置文件復制到你的springcloud模塊中
6.啟動seata
如果之前在其他ip啟動過，將file_store/data下的文件清掉，不然會報錯
7.springcloud代碼
去https://gitee.com/code_fun/example.git 把demo.zip下載跑就可以了，前提是建好數據庫哦
demo.sql有表結構，undo_log表每個庫都要有
如果上面demo.zip跑不通請移步https://gitee.com/sharehappy/learn/tree/master/springcloud_seata下載代碼或者進群：513650703討論
