}1、存储模式1、file存储模式默认支持的存储模式直接启动即可不需要改动任何文件file模式是单机模式全局事务会话信息会持久化到本地文件/bin/sessionStore/root.data性能较高具体的命令如下sh seata-server.sh -p 8091 -h 127.0.0.1 -m file2、db存储模式这个模式是高可用的模式全局事务会话信息通过db共享的性能较比file模式较差一些具体的实现步骤如下①创建数据库表结构如下-- the table to store GlobalSession data--全局事务表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_gmt_modified_status (gmt_modified, status), KEY idx_transaction_id (transaction_id)) ENGINE InnoDB DEFAULT CHARSET utf8; -- the table to store BranchSession data--分支事务表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 InnoDB DEFAULT CHARSET utf8; -- the table to store lock data--全局锁表CREATE 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;②设置事务日志存储方式进入conf/file.conf修改属性store.modedb③修改数据库连接db { datasource druid ##修改 dbType mysql driverClassName com.mysql.jdbc.Driver url jdbc:mysql://127.0.0.1:3306/seata ##修改 user mysql ##修改 password mysql ##修改 minConn 1 maxConn 10 globalTable global_table branchTable branch_table lockTable lock_table queryLimit 100 }④启动seataseata-server.bat -h 127.0.0.1 -p 8091 -m db -n 1关于后面的启动参数这里就不做陈述了上面表格有详解2、配置中心说明Seata根目录config有两个配置文件registry.conf和file.configregistry.con配置说明这个文件中只包含了两项配置属相registry和config源码如下registry { # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa type file nacos { serverAddr localhost namespace cluster default } eureka { serviceUrl http://localhost:8761/eureka application default weight 1 } redis { serverAddr localhost:6379 db 0 } zk { cluster default serverAddr 127.0.0.1:2181 session.timeout 6000 connect.timeout 2000 } consul { cluster default serverAddr 127.0.0.1:8500 } etcd3 { cluster default serverAddr http://localhost:2379 } sofa { serverAddr 127.0.0.1:9603 application default region DEFAULT_ZONE datacenter DefaultDataCenter cluster default group SEATA_GROUP addressWaitTime 3000 } file { name file.conf }} config { # file、nacos 、apollo、zk、consul、etcd3 type file nacos { serverAddr localhost namespace group SEATA_GROUP } consul { serverAddr 127.0.0.1:8500 } apollo { app.id seata-server apollo.meta http://192.168.1.204:8801 namespace application } zk { serverAddr 127.0.0.1:2181 session.timeout 6000 connect.timeout 2000 } etcd3 { serverAddr http://localhost:2379 } file { name file.conf }}registry它可以配置Seata服务注册的地址支持现在市面上绝大多数的注册中心组件配置也很简单只需要修改type即可然后在对应的配置下配置好对应服务的ip相关信息即可比如想用Nacos作为注册中心那就typenacos然后修改ip源码如下registry { # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa type nacos #修改按照上面注释的单词来填写 nacos { serverAddr 127.0.0.1:8848 #对应nacos的相关配置 namespace cluster default } # 以下代码省略...}这里注意一下这个type默认是file表示不用注册中心如果是file就可以不用注册中心快速运行Seata只不过file没有注册中心的动态发现和动态配置的功能config用于配置Seata服务端的配置文件地址意思就是说可以通过config配置来指定Seata服务端的配置信息的加载位置它支持从远程配置中心读取和本地文件读取两种方式如果配置为远程配置中心可以使用type指定配置形式和上面的registry一样config { # file、nacos 、apollo、zk、consul、etcd3 type nacos #修改 nacos { serverAddr 127.0.0.1:8848 #修改 namespace group SEATA_GROUP } # 以下代码省略...}需要注意的是如果这里的type是file的话他默认会加载file.conf文件中的配置信息那这里就需要讲解一下file.conf文件了file.conf配置说明此配置文件存储的是Seata服务端的配置信息完成配置是transport(协议配置)、server(服务端配置)、metrics(监控)transport {# tcp udt unix-domain-sockettype TCP#NIO NATIVEserver NIO#enable heartbeatheartbeat true# the client batch send request enableenableClientBatchSendRequest false#thread factory for nettythreadFactory {bossThreadPrefix NettyBossworkerThreadPrefix NettyServerNIOWorkerserverExecutorThreadPrefix NettyServerBizHandlershareBossWorker falseclientSelectorThreadPrefix NettyClientSelectorclientSelectorThreadSize 1clientWorkerThreadPrefix NettyClientWorkerThread# netty boss thread size,will not be used for UDTbossThreadSize 1#auto default pin or 8workerThreadSize default}shutdown {# when destroy server, wait secondswait 3}serialization seatacompressor none
