seata-server平台搭建

一、环境准备

​ 本文主要介绍如何搭建seata-server管理平台。前期准备如下：

组件 版本 备注
centos CentOS Linux release 8.4.2105 请自行搜索安装
nacos 2.2.1 请自行搜索安装
mysql 8.0.37 请自行搜索安装
openjdk 1.8.0_312-b07 请自行搜索安装
seata-server 1.6.1

seata-server1.6.1 下载地址

二、文件配置

​ 将下载的压缩包使用工具上传并解压。解压命令：

1
tar -zxvf seata-server-1.6.1.tar.gz

​ 解压后，进入文件目录的 conf 文件夹，需要进行相应的配置。先将 application.yml 进行备份

1
cp application.yml application_bk.yml

​ 修改 application.yml 的配置：

1
vim application.yml

​ 配置文件内容如下：

​ 配置文件修改后，需要导入sql脚本，sql脚本下载地址如下：https://gitee.com/seata-io/seata/blob/v1.6.1/script/server/db/mysql.sql。

三、启动

​ 由于配置中心和注册中心使用nacos，先启动nacos服务，然后在nacos中添加一个新的命名空间,配置文件中的namespace就是指定命名空间的id。点击创建配置，在创建页面，DATA_ID使用配置文件的data-id，Group使用配置文件的group。配置内容如下：

store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://172.148.2.18:3305/seata?useUnicode=true
store.db.user=root
store.db.password=123456
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

​ 进入 seata-server的bin目录，执行启动命令：

1
./seata-server.sh -p 8091 -h 172.148.2.18 -m db
  • -p 8091 : 指定 Seata Server 的服务端口（即 TC 的 RPC 通信端口，默认也是 8091）。TM / RM 通过这个端口和 Seata 通信。
  • -h 172.148.2.18: 指定 Seata Server 注册到注册中心时的 IP 地址，客户端就是通过这个 IP 找到 TC 的。默认是读取本地 IP，这里是显式指定为服务器的实际 IP。
  • -m db: 指定事务日志（如全局事务、分支事务）存储模式为数据库（db 模式），也可以为 file、redis、nacos 等，但最常用的是 db。

​ 启动命令如下：

​ 注意：seata-server默认启动占用的内存为2G，如果配置低，需要修改 bin 目录中 seata-server.sh文件，将JVM_XMX、JVM_XMS、JVM_XMN几个参数值修改为512M、256M、256M。
