Docker+nacos+seata1.3.0安装与使用配置教程
在此之前我搞了一天，虽然seata好用，用起来也超级简单，但是安装配置是真的麻烦，遇见了各种坑，下面来进入正题。o(╥﹏╥)o

一 . 版本注意：如果版本不匹配也会有各种报错，可以根据官网匹配版本。
seata：1.3.0alibaba.cloud：2.2.3.RELEASEnacos：2.0.2二. docker安装搭建seata服务端2.1 下载seata镜像
docker pull seataio/seata-server:1.3.02.2 在Linux目录下创建registry.conf，我的路径在/data/seate/registry.conf，接下来的所有创建都在这个目录下
cd /datamkdir seatevim registry.conf2.3 registry.conf中的内容如下
registry { type = "nacos" nacos { application = "seata-server" serverAddr = "127.0.0.1:8848" group = "SEATA_GROUP" namespace = "" cluster = "default" username = "" password = "" }} config { type = "nacos" nacos { serverAddr = "127.0.0.1:8848" namespace = "" group = "SEATA_GROUP" username = "" password = "" }}注意registry和config需要在同一个组下,注册中心我用的是nacos，注意nacos的地址要改。
----->>>这里我插一句，需要新建一个数据库seata，并且新建三张表，
-- -------------------------------- The script used when storeMode is 'db' ---------------------------------- the table to store GlobalSession dataCREATE 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_gmt_modified_status` (`gmt_modified`, `status`), KEY `idx_transaction_id` (`transaction_id`)) ENGINE = InnoDB DEFAULT CHARSET = utf8; -- the table to store BranchSession dataCREATE 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 = InnoDB DEFAULT CHARSET = utf8; -- the table to store lock dataCREATE TABLE IF NOT EXISTS `lock_table`( `row_key` VARCHAR(128) NOT NULL, `xid` VARCHAR(96), `transaction_id` BIGINT, `branch_id` BIGINT NOT NULL, `resource_id` VARCHAR(256), `table_name` VARCHAR(32), `pk` VARCHAR(36), `gmt_create` DATETIME, `gmt_modified` DATETIME, PRIMARY KEY (`row_key`), KEY `idx_branch_id` (`branch_id`)) ENGINE = InnoDB DEFAULT CHARSET = utf8;实现分布式每个业务库都要加一张表undo_log，不然会报错，
CREATE TABLE `undo_log` ( `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主键', `branch_id` bigint(20) NOT NULL COMMENT 'branch transaction id', `xid` varchar(100) 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', PRIMARY KEY (`id`), UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COMMENT='AT transaction mode undo table';2.4 创建推送配置文件 vim config.txt，是将文件中的配置推送到nacos中去。
vim config.txtservice.vgroupMapping.btb_tx_group=defaultstore.mode=dbstore.db.datasource=druidstore.db.dbType=mysqlstore.db.driverClassName=com.mysql.cj.jdbc.Driverstore.db.url=jdbc:mysql://172.0.0.1:3306/seata?useUnicode=truestore.db.user=rootstore.db.password=rootstore.db.minConn=5store.db.maxConn=30store.db.globalTable=global_tablestore.db.branchTable=branch_tablestore.db.queryLimit=100store.db.lockTable=lock_tablestore.db.maxWait=5000注意btb_tx_group需要与客户端保持一致,顺便注意数据库驱动，如果是8以上用我的这个驱动，5.7的用com.mysql.jdbc.Driver
2.5 创建推送脚本，因为执行脚本要在config.txt的下一层，所有加一层目录
mkdir shcd shvim nacos-config.sh内容如下：最好不要有任何的修改

"else echo " init nacos config fail. "fi2.6 执行推送脚本，后面是nacos的ip地址，如果端口不是8848还需要加一个-p 8884你的端口
bash nacos-config.sh -h 127.0.0.12.7 创建容器，注意SEATA_IP如果是阿里云服务器需要写外网ip
docker run -d --restart always --name seata-server -p 8091:8091 -e SEATA_IP=172.0.0.1 -e SEATA_CONFIG_NAME=file:/data/seata/registry -v /data/seata:/data/seata seataio/seata-server:1.3.0三 . 客户端（也就是微服务，项目中使用seata）3.1 pom.xml 引入依赖
注意这里一定要剔除原来自带的 io.seata包，并且服务端和客户端的包版本要一致。
3.2 配置项目配置文件
#seataseata.application-id=${spring.application.name}seata.tx-service-group=btb_tx_groupseata.config.type=nacosseata.config.nacos.server-addr=172.0.0.1:8848seata.config.nacos.group=SEATA_GROUPseata.registry.type=nacosseata.registry.nacos.application=seata-serverseata.registry.nacos.server-addr=172.0.0.1:8848seata.registry.nacos.group=SEATA_GROUP注意：这里的btb_tx_group要跟服务端的vgroupMapping后面的key保持一致，
如：service.vgroupMapping.btb_tx_group=default
3.3 加入注解使用
@GlobalTransactional扩展： 我用的是一个数据库，执行报错，说我缺少主键，于是我在表undo_log加了一个增的主键id，上面的创建undo_log表的sql是我加了id的，官方给的是没有id的。请知晓！！！！
问题：单数源是有报错的，原因是因为我是一个数据库，需要设置代理配置如下 ，根据自己实际情况是指配置文件，不然会报错
#单数据源seata.enable-auto-data-source-proxy=true#多数据源seata.enable-auto-data-source-proxy=false到此这篇关于Docker+nacos+seata1.3.0安装与使用的文章就介绍到这了,更多相关Docker+nacos+seata安装使用内容请搜索脚本之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持脚本之家！
