开始语

一位普通的程序员，慢慢在努力变强！

温馨提示：如果没有安装docker的同学前往下列步骤⬇️

部署docker

部署docker-compose

部署MySQL安装官网的部署方式

部署Nacos新版2.0（最细步骤）

温馨提示：本章节部署方式Nacos注册中心+MySQL存储！

⏬下载最新版本1.6版本seata

# 下载文件，但是这个下载很慢，下方提供了 三个可执行文件

      - "/usr/share/zoneinfo/Asia/Shanghai:/etc/timezone"
      - "./application.yml:/seata-server/resources/application.yml"

三个文件的描述和注意事项

1. 三个文放置同一个目录下
2. application中的配置一个都不能少，因为是注册+mysql的模式
3. 检查好nacos+mysql是否都部署号，并且配置是否齐全

还没完，接下来再MySQL中添加表、在Nacos创建对应的配置

️MySQL创建表

️Nacos创建命名空间+properties配置文件

 

1. 创建seataServer.properties配置
2. Data ID=seataServer.properties
3. Group=SEATA_GROUP
4. 配置文件格式=Properties
5. 配置如下：

store.mode=db

#-----db-----

store.db.datasource=druid

store.db.dbType=mysql

# 需要根据mysql的版本调整driverClassName

# mysql8及以上版本对应的driver：com.mysql.cj.jdbc.Driver

# mysql8以下版本的driver：com.mysql.jdbc.Driver

store.db.driverClassName=com.mysql.cj.jdbc.Driver

store.db.url=jdbc:mysql://192.168.125.122:3306/seata-server?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useSSL=false

store.db.user=root

store.db.password=wang_ROOT_123

# 数据库初始连接数

store.db.minConn=1

# 数据库最大连接数

store.db.maxConn=20

# 获取连接时最大等待时间 默认5000，单位毫秒

store.db.maxWait=5000

# 全局事务表名 默认global_table

store.db.globalTable=global_table

# 分支事务表名 默认branch_table

store.db.branchTable=branch_table

# 全局锁表名 默认lock_table

store.db.lockTable=lock_table

# 查询全局事务一次的最大条数 默认100

store.db.queryLimit=100

# undo保留天数 默认7天,log_status=1（附录3）和未正常清理的undo

server.undo.logSaveDays=7

# undo清理线程间隔时间 默认86400000，单位毫秒

server.undo.logDeletePeriod=86400000

# 二阶段提交重试超时时长 单位ms,s,m,h,d,对应毫秒,秒,分,小时,天,默认毫秒。默认值-1表示无限重试

# 公式: timeout>=now-globalTransactionBeginTime,true表示超时则不再重试

# 注: 达到超时时间后将不会做任何重试,有数据不一致风险,除非业务自行可校准数据,否者慎用

server.maxCommitRetryTimeout=-1

# 二阶段回滚重试超时时长

server.maxRollbackRetryTimeout=-1

# 二阶段提交未完成状态全局事务重试提交线程间隔时间 默认1000，单位毫秒

server.recovery.committingRetryPeriod=1000

# 二阶段异步提交状态重试提交线程间隔时间 默认1000，单位毫秒

server.recovery.asynCommittingRetryPeriod=1000

# 二阶段回滚状态重试回滚线程间隔时间 默认1000，单位毫秒

server.recovery.rollbackingRetryPeriod=1000

# 超时状态检测重试线程间隔时间 默认1000，单位毫秒，检测出超时将全局事务置入回滚会话管理器

server.recovery.timeoutRetryPeriod=1000

 

️docker-compose部署seata

docker - compose - f seata - docker - compose . yml up - d

检查是否启动成功

[root@VM-4-6-centos seata-docker]# docker-compose ps
