-- 版本说明：nacos（1.1.4）、seata（0.9.0）
1、下载压缩包：https://github.com/seata/seata/releases，并解压
2、修改registry.conf
registry {
type = "nacos"
nacos {
serverAddr = "47.110.140.69:8848"
namespace = ""
cluster = "default"
}
file {
name = "file.conf"
}
}
config {
type = "nacos"
nacos {
serverAddr = "47.110.140.69:8848"
namespace = ""
}
file {
name = "file.conf"
}
}
踩坑说明：
a、serverAddr： nacos地址，必须采用ip + 端口号
b、namespace：命名空间，不能写public，必须写 “”
3、修改file.conf
transport {
# tcp udt unix-domain-socket
type = "TCP"
#NIO NATIVE
server = "NIO"
#enable heartbeat
heartbeat = true
#thread factory for netty
thread-factory {
boss-thread-prefix = "NettyBoss"
worker-thread-prefix = "NettyServerNIOWorker"
server-executor-thread-prefix = "NettyServerBizHandler"
share-boss-worker = false
client-selector-thread-prefix = "NettyClientSelector"
client-selector-thread-size = 1
client-worker-thread-prefix = "NettyClientWorkerThread"
# netty boss thread size,will not be used for UDT
boss-thread-size = 1
#auto default pin or 8
worker-thread-size = 8
}
shutdown {
# when destroy server, wait seconds
wait = 3
}
serialization = "seata"
compressor = "none"
}
service {
#vgroup->rgroup
vgroup_mapping.sie-shop-group = "default" # 配置模块事务名称
vgroup_mapping.sie-wallet-group = "default" # 配置模块事务名称
#only support single node
default.grouplist = "47.110.140.69:8091"
#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"
}
client {
async.commit.buffer.limit = 10000
lock {
retry.internal = 10
retry.times = 30
}
report.retry.count = 5
tm.commit.retry.count = 1
tm.rollback.retry.count = 1
}
## transaction log store

# 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
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://rm-bp156s27eh61ww736mo.mysql.rds.aliyuncs.com/seata"
user = "root"
password = "1Qaz2wsx"
min-conn = 1
max-conn = 3
global.table = "global_table"
branch.table = "branch_table"
lock-table = "lock_table"
query-limit = 100
}
}
lock {
## the lock store mode: local銆乺emote
mode = "remote"
local {
## store locks in user's database
}
remote {
## store locks in the seata's server
}
}
recovery {
#schedule committing retry period in milliseconds
committing-retry-period = 1000
#schedule asyn committing retry period in milliseconds
asyn-committing-retry-period = 1000
#schedule rollbacking retry period in milliseconds
rollbacking-retry-period = 1000
#schedule timeout retry period in milliseconds
timeout-retry-period = 1000
}
transaction {
undo.data.validation = true
undo.log.serialization = "jackson"
undo.log.save.days = 7
#schedule delete expired undo_log in milliseconds
undo.log.delete.period = 86400000
undo.log.table = "undo_log"
}
## metrics settings
metrics {
enabled = false
registry-type = "compact"
# multi exporters use comma divided
exporter-list = "prometheus"
exporter-prometheus-port = 9898
}
support {
## spring
spring {
# auto proxy the DataSource bean
datasource.autoproxy = false
}
}
主要修改service和store中的内容，其余选项不用更改，默认即可
a、service：配置 vgroup_mapping.xxxxx = "default"，哪个模块需要分布式事务就配置
b、store ： mode = "db"表示采用db配置；store中的db配置数据库信息，在此之前需要将db_store.sql、db_undo_log.sql这两个sql文件导入数据库即可
4、修改nacos-config.txt
transport.type=TCP
transport.server=NIO
transport.heartbeat=true
transport.thread-factory.boss-thread-prefix=NettyBoss
transport.thread-factory.worker-thread-prefix=NettyServerNIOWorker
transport.thread-factory.server-executor-thread-prefix=NettyServerBizHandler
transport.thread-factory.share-boss-worker=false
transport.thread-factory.client-selector-thread-prefix=NettyClientSelector
transport.thread-factory.client-selector-thread-size=1
transport.thread-factory.client-worker-thread-prefix=NettyClientWorkerThread
transport.thread-factory.boss-thread-size=1
transport.thread-factory.worker-thread-size=8
transport.shutdown.wait=3
service.vgroup_mapping.sie-shop-group=default
service.vgroup_mapping.sie-wallet-group=default
service.enableDegrade=false
service.disable=false
service.max.commit.retry.timeout=-1
service.max.rollback.retry.timeout=-1
client.async.commit.buffer.limit=10000
client.lock.retry.internal=10
client.lock.retry.times=30
client.lock.retry.policy.branch-rollback-on-conflict=true
client.table.meta.check.enable=true
client.report.retry.count=5
client.tm.commit.retry.count=1
client.tm.rollback.retry.count=1
store.mode=file
store.file.dir=file_store/data
store.file.max-branch-session-size=16384
store.file.max-global-session-size=512
store.file.file-write-buffer-cache-size=16384
store.file.flush-disk-mode=async
store.file.session.reload.read_size=100
store.db.datasource=dbcp
store.db.db-type=mysql
store.db.driver-class-name=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://rm-bp156s27eh61ww736mo.mysql.rds.aliyuncs.com/seata?Unicode=true
store.db.user=root
store.db.password=1Qaz2wsx
store.db.min-conn=1
store.db.max-conn=3
store.db.global.table=global_table
store.db.branch.table=branch_table
store.db.query-limit=100
store.db.lock-table=lock_table
recovery.committing-retry-period=1000
recovery.asyn-committing-retry-period=1000
recovery.rollbacking-retry-period=1000
recovery.timeout-retry-period=1000
transaction.undo.data.validation=true
transaction.undo.log.serialization=jackson
transaction.undo.log.save.days=7
transaction.undo.log.delete.period=86400000
transaction.undo.log.table=undo_log
transport.serialization=seata
transport.compressor=none
metrics.enabled=false
metrics.registry-type=compact
metrics.exporter-list=prometheus
metrics.exporter-prometheus-port=9898
support.spring.datasource.autoproxy=false
修改文件中的service.vgroup_mapping和store.db即可
5、将seata配置文件导入nacos中
cd /conf
sh nacos-config.sh 127.0.0.1
此时会看到nacos配置中心多了很多SEATA_GROUP的配置信息
6、启动seata
nohup ./seata-server.sh -p 8091 -h 47.110.140.69 -m file &
7、Spring Cloud 整合Seata
7.1、加入依赖
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-seata</artifactId>
</dependency>
7.2、动态数据源配置
@Configuration
public class DataSourceProxyConfig {
@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DruidDataSource druidDataSource() {
return new DruidDataSource();
}
@Primary
@Bean
public DataSourceProxy dataSource(DruidDataSource druidDataSource) {
return new DataSourceProxy(druidDataSource);
}
}
7.3、修改bootstrap.yml
spring:
cloud:
alibaba:
seata:
tx-service-group: ${spring.application.name}-group
说明：tx-service-group 要与配置的事务组名称一致
7.4、在根目录resources中加入registry.conf文件
registry {
type = "nacos"
nacos {
serverAddr = "47.110.140.69:8848"
namespace = ""
cluster = "default"
}
}
config {
type = "nacos"
nacos {
serverAddr = "47.110.140.69:8848"
namespace = ""
}
}
注意：namespace一定要写成""
