## transaction log store
store {
## store mode: file、db
mode = "db" 修改这里,表明事务信息用db存储
## file store 当mode=db时,此部分配置就不生效了,这是mode=file的配置
file {
dir = "sessionStore"
# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions
max-branch-session-size = 16384
# globe session size , if exceeded throws exceptions
max-global-session-size = 512
# file buffer size , if exceeded allocate new buffer
file-write-buffer-cache-size = 16384
# when recover batch read size
session.reload.read_size = 100
# async, sync
flush-disk-mode = async
}
## database store mode=db时,事务日志存储会存储在这个配置的数据库里
db {
## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp) etc.
datasource = "dbcp"
## mysql/oracle/h2/oceanbase etc.
db-type = "mysql"
driver-class-name = "com.mysql.jdbc.Driver"
url = "jdbc:mysql://116.62.62.26/seat-server" 修改这里
user = "root" 修改这里
password = "root" 修改这里
min-conn = 1
max-conn = 3
global.table = "global_table"
branch.table = "branch_table"
lock-table = "lock_table"
query-limit = 100
}
}
由于此demo我们使用db模式存储事务日志,所以,我们要创建三张表:global_table,branch_table,lock_table 数据表在下载的seat-server/conf中
由于存储undo_log是在业务库中,所以在每个业务库中,还要创建undo_log表 数据表在下载的seat-server/conf中
由于我自定义了事务组名称,所以这里也做了修改:
service {
#vgroup->rgroup
# seata版本1.0.0后客户端file.conf文件中vgroup_mapping要改成vgroupMapping
vgroup_mapping.fsp_tx_group = "default" 修改这里,fsp_tx_group这个事务组名称是我自定义的,一定要与client端的这个配置一致!否则会报错!
#only support single node
default.grouplist = "127.0.0.1:8091"
#degrade current not support
enableDegrade = false
#disable
disable = false
#unit ms,s,m,h,d represents milliseconds, seconds, minutes, hours, days, default permanent
max.commit.retry.timeout = "-1"
max.rollback.retry.timeout = "-1"
}
registry {
# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
type = "eureka" 修改这里,指明注册中心使用什么
nacos {
serverAddr = "localhost"
namespace = ""
cluster = "default"
}
eureka {
serviceUrl = "http://localhost:10086/eureka" 修改这里
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"
}
}
如果是在windows下启动seata-server,现在已经完成配置修改了,等eureka启动后,就可以启动seata-server了:执行/bin/seata-server.bat即可。默认端口8091
