Seata服务高可用+负载均衡搭建安装、快速启动

参考官方文档：

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

描述

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。

高可用部署

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

[root@localhost conf]# pwd/usr/local/seata1.3/seata/conf[root@localhost conf]# lsfile.conf file.conf.example logback.xml META-INF README.md README-zh.md registry.conf

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

registry { # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa type = "nacos" nacos { application = "seata-server" serverAddr = "192.168.128.20" group = "SEATA_GROUP" namespace = "1c53b59e-9f3d-44a4-b2d7-5faaea25b3c6" cluster = "default" username = "" password = "" } eureka { serviceUrl = "http://localhost:8761/eureka" application = "default" weight = "1" } 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 = "" password = "" } 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" }}config { # file、nacos 、apollo、zk、consul、etcd3 type = "nacos" nacos { serverAddr = "192.168.128.20" namespace = "aebcc8df-bcca-4f1d-8f27-fa98828753d7" group = "SEATA_GROUP" username = "" password = "" } consul { serverAddr = "127.0.0.1:8500" } 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 = "" password = "" } etcd3 { serverAddr = "http://localhost:2379" } file { name = "file.conf" }}

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，

步骤：

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

"else echo " init nacos config fail. "fi

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

sh nacos-config.sh -h 192.168.128.20 -p 8848 -g SEATA_GROUP -t aebcc8df-bcca-4f1d-8f27-fa98828753d7

执行完成以后即可看到nacos配置

启动

1.进入bin目录下所示

[root@localhost bin]# pwd/usr/local/seata1.3/seata/bin[root@localhost bin]# lsnohup.out seata-server.bat seata-server.sh

2.三台机器分别执行如下命令：

nohup sh ./seata-server.sh -p 8091 -h 192.168.128.36 -m db -n 3 &nohup sh ./seata-server.sh -p 8091 -h 192.168.128.37 -m db -n 2 &nohup sh ./seata-server.sh -p 8091 -h 192.168.128.32 -m db -n 1 &

windows下配置和启动

1.windows启动命令（本机）

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

registry.conf配置

registry { # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa type = "nacos" nacos { application = "seata-server" serverAddr = "192.168.128.20" group = "SEATA_GROUP" namespace = "aebcc8df-bcca-4f1d-8f27-fa98828753d7" cluster = "default" username = "" password = "" } eureka { serviceUrl = "http://localhost:8761/eureka" application = "default" weight = "1" } 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 = "" password = "" } 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" }}config { # file、nacos 、apollo、zk、consul、etcd3 type = "nacos" nacos { serverAddr = "192.168.128.20" namespace = "aebcc8df-bcca-4f1d-8f27-fa98828753d7" group = "SEATA_GROUP" username = "" password = "" } consul { serverAddr = "127.0.0.1:8500" } 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 = "" password = "" } etcd3 { serverAddr = "http://localhost:2379" } file { name = "file.conf" }}

seata1.3 nacos1.3.0配置中心

1.下载seata-dev-tools

https://gitee.com/seata-io/seata

2.下载seata1.3

3.cd script/config-center/nacos/

4.vim nacos-config.sh 44行配置nacos的地址、端口、账号密码

if [[ -z ${host} ]]; then

host=nacos.baidu.com

if [[ -z ${port} ]]; then

port=80

if [[ -z ${group} ]]; then

group="SEATA_GROUP"

if [[ -z ${tenant} ]]; then

tenant=""

if [[ -z ${username} ]]; then

username="nacos"

if [[ -z ${password} ]]; then

password="hon20"

5. sh nacos-config.sh 上传配置信息

6.unzip seata1.3 下载seata1.3解压

7.cd seata1.3/conf

8.vim file.conf 这里我使用db模式

## transaction log store, only used in seata-server

store {

## store mode: file、db、redis

mode = "db"

## database store property

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://39.97.999.29:3306/seata"

user = "root"

password = "ho20"

minConn = 5

maxConn = 30

globalTable = "global_table"

branchTable = "branch_table"

lockTable = "lock_table"

queryLimit = 100

maxWait = 5000

}

service {

vgroupMapping.storage-service-group= "default"

vgroupMapping.order-service-group= "default"

vgroupMapping.business-service-group= "default"

}

9.配置数据库文件 seata数据库

10.每个需要全局事务的数据库中，放一个undo_log的表

SET FOREIGN_KEY_CHECKS = 1;

11.vim registry.conf

registry {

# file 、nacos 、eureka、redis、zk、consul、etcd3、sofa

type = "nacos"

nacos {

application = "seata-server"

serverAddr = "nacos.baidu.com:80"

group = "SEATA_GROUP"

namespace = ""

cluster = "default"

username = "nacos"

password = "ho20"

}

config {

# file、nacos 、apollo、zk、consul、etcd3

type = "nacos"

nacos {

serverAddr = "nacos.baidu.com:80"

namespace = ""

group = "SEATA_GROUP"

username = "nacos"

password = "ho0"

}

12. cd bin

13.sh seata-server.sh -p 8091 -h 192.168.0.199 -m file &> seata.log & -h如果是外网的话，请设置为外网IP，否则出错

14. 代码中配置seata tips:需要在每个分布式事务的微服务中都配置

seata:

tx-service-group: test_tx_service_group

config:

type: nacos

nacos:

serverAddr: ${spring.cloud.nacos.server-addr}

group: SEATA_GROUP

username: ${spring.cloud.nacos.username}

password: ${spring.cloud.nacos.password}

registry:

type: nacos

nacos:

server-addr: ${spring.cloud.nacos.server-addr}

group: SEATA_GROUP

username: ${spring.cloud.nacos.username}

password: ${spring.cloud.nacos.password}

15:在业务开始的地方添加注解@GlobalTransactional ，该注解下的所有增删改都会走分布式事务

16.seata常见问题 https://seata.io/zh-cn/docs/overview/faq.html

17.集群：在其他机器上，再开启一个seata，配置不变。
