Seata 部署手册

适用与2.2.0版本

服务端

Docker方式

store.mode=db 方式不推荐,需要将mysql驱动映射到容器中的lib/jdbc或libs/jdbc中,试了两种方式,都是报错,加之Seata运行只需要安装Java环境即可,所以放弃使用docke运行

Jar运行方式

下载

修改配置

正式环境注册和配置中心推荐nacos,store推荐db模式

初始化数据库

SQL路径:seata-server\script\server\db

运行

一定要指定当前服务器的IP,不然在Nacos里面注册的IP不是真实的

sh ./bin/seata-server.sh -h 192.168.1.100

查看运行日志

tail -f /root/logs/seata/seata-server.8091.all.log
