Seata服务高可用+负载均衡搭建

参考官方文档：

http://seata.io/zh-cn/docs/ops/deploy-guide-beginner.html

目前三台服务器，分别在 192.168.128.36、192.168.128.37、192.168.128.32 上，通过三台服务器达到高可用，使用spring cloud ribbon达到负载均衡。

1.高可用部署参照：

http://seata.io/zh-cn/docs/ops/deploy-ha.html

seata github项目地址

https://github.com/seata/seata

2.安装目录

3.registry.conf配置如下：（file.conf不用管，因为用的nacos）

4.在mysql（ 官方db地址 ）分别创建 global_table, branch_table, lock_table 表。

5.在nacos添加 namespace=seata

6.导入seata配置文件，

6.1修改 nacos-config.sh 脚本，以适用自己的nacos配置， 官方配置

6.2修改 config.txt 文件，以适用自己的nacos配置， 官方配置

7.执行 nacos-config.sh 脚本

执行完成以后即可看到nacos配置

1.进入 bin 目录下所示

2.三台机器分别执行如下命令：

1.windows启动命令（本机）

.\seata-server.bat -p 28091 -m db -n 4

客户端要注册到nacos

store {

mode = "db"

file {

## store location dir

dir = "sessionStore"

# branch session size , if exceeded first try compress lockkey, still exceeded throws exceptions

maxBranchSessionSize = 16384

# globe session size , if exceeded throws exceptions

maxGlobalSessionSize = 512

# file buffer size , if exceeded allocate new buffer

fileWriteBufferCacheSize = 16384

# when recover batch read size

sessionReloadReadSize = 100

# async, sync

flushDiskMode = async

}

db {

## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.

datasource = "druid"

## mysql/oracle/postgresql/h2/oceanbase etc.

dbType = "mysql"

driverClassName = "com.mysql.jdbc.Driver"

url = "jdbc: mysql://192.168.200.161:3307/seata1.3 "

user = "root"

password = "123456"

minConn = 5

maxConn = 30

globalTable = "global_table"

lockTable = "lock_table"

queryLimit = 100

maxWait = 5000

}

redis {

}

registry.conf 采用nacos注册

eureka {

serviceUrl = " http://localhost:8761/eureka "

}

redis {

serverAddr = "localhost:6379"

db = 0

password = ""

cluster = "default"

timeout = 0

}

zk {

cluster = "default"

serverAddr = "127.0.0.1:2181"

sessionTimeout = 6000

connectTimeout = 2000

username = ""

}

consul {

}

file {

}

}

config {

nacos {

consul {

}

apollo {

appId = "seata-server"

apolloMeta = "http://192.168.1.204:8801"

namespace = "application"

}

zk {

serverAddr = "127.0.0.1:2181"

sessionTimeout = 6000

connectTimeout = 2000

username = ""

}

etcd3 {

serverAddr = " http://localhost:2379 "

}

file {

name = "file.conf"

}

}
