安装Seata1.8.0
1、拷贝数据
启动容器
docker run -id --name seata-server -p 8091:8091 -p 7091:7091 seataio/seata-server:1.8.0
拷贝文件
docker cp seata-server:/seata-server/resources ./
创建PVC:seata-server-config-180,把resource文件里的内容解压并拷贝进去,方法有很多,略写了
2、修改配置
修改之前,我们需要去nacos中创建命名空间:seata,Group:SEATA_GROUP_180,
配置内容:
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://nacos-mysql.middlew.svc.cluster.local:3306/seata_180?useUnicode=true&characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
#连接seata数据库账号、密码
store.db.user=seata
store.db.password=xxxxxxxxxxxx
# 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
service.vgroupMapping.aps_tx_group=default
# 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
修改服务的配置文件,application.yml文件内容,与上面创建的对应:
server:
port: 7091
spring:
application:
name: seata-server
logging:
# config: classpath:logback-spring.xml
file:
path: ${user.home}/logs/seata
console:
user:
username: seata
password: seata
seata:
# tx-service-group: aps_tx_group
config:
# support: nacos, consul, apollo, zk, etcd3
type: nacos
nacos:
server-addr: nacos-clusterip.middlew.svc.cluster.local:8848 #nacos地址
namespace: seata #nacos中需要存在该命名空间
group: SEATA_GROUP_180 #需要提前在nacos中创建该配置文件
username: nacos #nacos用户
password: nacos #nacos密码
data-id: seataServer.properties
registry:
# support: nacos, eureka, redis, zk, consul, etcd3, sofa
type: nacos
nacos:
application: seata-server
server-addr: nacos-clusterip.middlew.svc.cluster.local:8848
group: SEATA_GROUP_180 #同上,需要提前创建
namespace: seata
# tc集群名称
cluster: default
username: nacos
password: nacos
# server:
# service-port: 8091 #If not configured, the default is '${server.port} + 1000'
security:
secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
tokenValidityInMilliseconds: 1800000
ignore:
urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login
修改完成后,替换下pvc里的application.yml文件
3、初始化数据库
上一步指定了数据源位置,连接数据库后执行sql脚本初始化
执行sql文件:
-- MySQL dump 10.13 Distrib 8.0.27, for Linux (x86_64)
--
-- Host: localhost Database: seata_180
-- ------------------------------------------------------
