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：

--
-- Host: localhost    Database: seata_180
