2. Windows下部署Seata1.5.2 2.1 创建回滚日志表undo_log 2.2 创建Seata服务端需要的四张表 2.3 在nacos创建seata命名空间添加seataServer.yml配置 2.4 修改本地D:/tool/seata-server-1.5.2/seata/conf/applicaltion.yml文件 2.5 启动Seata 2.6 测试
3. 解决Seata无法启动问题 1. 版本说明 1 spring-cloud-alibaba:2021.0.4.0 对应 seata-all:1.5.2所以选择 Seata1.5.2 版本 2目前 Seata 支持的 JDK版本为 JDK8、JDK11这里使用JDK8。
4. Windows下部署Seata1.5.2 2.1 创建回滚日志表undo_log 注意需要用到分布式事务的数据库都要创建这个表。 CREATE TABLE IF NOT EXISTS undo_log (branch_id BIGINT NOT NULL COMMENT branch transaction id,xid VARCHAR(128) NOT NULL COMMENT global transaction id,context VARCHAR(128) NOT NULL COMMENT undo_log context,such as serialization,rollback_info LONGBLOB NOT NULL COMMENT rollback info,log_status INT(11) NOT NULL COMMENT 0:normal status,1:defense status,log_created DATETIME(6) NOT NULL COMMENT create datetime,log_modified DATETIME(6) NOT NULL COMMENT modify datetime,UNIQUE KEY ux_undo_log (xid, branch_id)) ENGINE InnoDB AUTO_INCREMENT 1 DEFAULT CHARSET utf8mb4 COMMENT AT transaction mode undo table; ALTER TABLE undo_log ADD INDEX ix_log_created (log_created); 2.2 创建Seata服务端需要的四张表 注意Seata存储模式store.modedb在Seata服务端需要连接的数据路seata里创建一下四张表。 – ——————————– The script used when storeMode is db ——————————– – the table to store GlobalSession data CREATE TABLE IF NOT EXISTS global_table (xid VARCHAR(128) NOT NULL,transaction_id BIGINT,status TINYINT NOT NULL,application_id VARCHAR(32),transaction_service_group VARCHAR(32),transaction_name VARCHAR(128),timeout INT,begin_time BIGINT,application_data VARCHAR(2000),gmt_create DATETIME,gmt_modified DATETIME,PRIMARY KEY (xid),KEY idx_status_gmt_modified (status , gmt_modified),KEY idx_transaction_id (transaction_id) ) ENGINE InnoDBDEFAULT CHARSET utf8mb4;– the table to store BranchSession data CREATE TABLE IF NOT EXISTS branch_table (branch_id BIGINT NOT NULL,xid VARCHAR(128) NOT NULL,transaction_id BIGINT,resource_group_id VARCHAR(32),resource_id VARCHAR(256),branch_type VARCHAR(8),status TINYINT,client_id VARCHAR(64),application_data VARCHAR(2000),gmt_create DATETIME(6),gmt_modified DATETIME(6),PRIMARY KEY (branch_id),KEY idx_xid (xid) ) ENGINE InnoDBDEFAULT CHARSET utf8mb4;– the table to store lock data CREATE TABLE IF NOT EXISTS lock_table (row_key VARCHAR(128) NOT NULL,xid VARCHAR(128),transaction_id BIGINT,branch_id BIGINT NOT NULL,resource_id VARCHAR(256),table_name VARCHAR(32),pk VARCHAR(36),status TINYINT NOT NULL DEFAULT 0 COMMENT 0:locked ,1:rollbacking,gmt_create DATETIME,gmt_modified DATETIME,PRIMARY KEY (row_key),KEY idx_status (status),KEY idx_branch_id (branch_id),KEY idx_xid_and_branch_id (xid , branch_id) ) ENGINE InnoDBDEFAULT CHARSET utf8mb4;CREATE TABLE IF NOT EXISTS distributed_lock (lock_key CHAR(20) NOT NULL,lock_value VARCHAR(20) NOT NULL,expire BIGINT,primary key (lock_key) ) ENGINE InnoDBDEFAULT CHARSET utf8mb4;INSERT INTO distributed_lock (lock_key, lock_value, expire) VALUES (AsyncCommitting, , 0); INSERT INTO distributed_lock (lock_key, lock_value, expire) VALUES (RetryCommitting, , 0); INSERT INTO distributed_lock (lock_key, lock_value, expire) VALUES (RetryRollbacking, , 0); INSERT INTO distributed_lock (lock_key, lock_value, expire) VALUES (TxTimeoutCheck, , 0); 2.3 在nacos创建seata命名空间添加seataServer.yml配置 seataServer.yml如下 内容如下 service:vgroupMapping:default_tx_group: default store:db:datasource: druiddbType: mysqldriverClassName: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://172.xxx.xxx.xxx:9906/seata?useUnicodetrueuser: rootpassword: rootminConn: 5maxConn: 30globalTable: global_tablebranchTable: branch_tablelockTable: lock_tabledistributedLockTable: distributed_lockqueryLimit: 100maxWait: 5000mode: db 2.4 修改本地D:/tool/seata-server-1.5.2/seata/conf/applicaltion.yml文件 server:port: 7091spring:application:name: seata-serverlogging:config: classpath:logback-spring.xmlfile:path: \({user.home}/logs/seataextend:logstash-appender:destination: 127.0.0.1:4560kafka-appender:bootstrap-servers: 127.0.0.1:9092topic: logback_to_logstashconsole:user:username: seatapassword: seataseata:config:# support: nacos, consul, apollo, zk, etcd3type: nacosnacos:server-addr: 172.xxx.xxx.xxx:8848 #请把localhost改为nacos的ipnamespace: seata # 命名空间group: SEATA_GROUPusername: nacos #nacos的账户password: nacos #nacos的密码data-id: seataServer.ymlregistry:# support: nacos, eureka, redis, zk, consul, etcd3, sofatype: nacosnacos:application: seata-serverserver-addr: 172.xxx.xxx.xxx:8848 #请把localhost改为nacos的ipnamespace: seata # 命名空间group: SEATA_GROUPcluster: defaultusername: nacos #nacos的账户password: nacos #nacos的密码#store:# support: file 、 db 、 redis#mode: file# server:# service-port: 8091 #If not configured, the default is \){server.port} 1000security:secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017tokenValidityInMilliseconds: 1800000ignore:urls: /,//*.css,//.js,/**/.html,//*.map,//.svg,/**/.png,//*.ico,/console-fe/public/,/api/v1/auth/login 2.5 启动Seata seata-server.bat -h 127.0.0.1 -m db 2.6 测试 浏览器输入网址http://localhost:7091/输入用户名和密码登录Seata。 注意登录Seata的用户名密码默认是seata seata可自定配置修改application.yml的配置如下 3. 解决Seata无法启动问题 当在Windows下进入Seata的bin目录下输入cmd回车输入Seata启动命令如下 seata-server.bat -h 127.0.0.1 -m db 1报错信息如下 2错误原因 1在启动Seata Server时Java虚拟机不认识CMSParallelRemarkEnabled 这个选项。 2CMSParallelRemarkEnabled 是与 CMSConcurrent Mark-Sweep垃圾回收器相关的选项但在较新的 Java 版本中被移除了。 注意目前Seata支持JDK8或JDK11。 3解决方案 打开seata/bin目录下的seata-server.bat文件将以下配置 if %JAVACMD% set JAVACMDjava 修改为如下 // 本地jdk路径 if %JAVACMD% set JAVACMDD:\Java\jdk1.8.0_251\bin\java.exe
