- 版本问题 seata 1.5和1.5之前的目录结构不同,使用docker修改的配置文件也不同
1.4的左右
1.5之后
- docker 挂载文件也不同
1.5之前是使用自己写的挂载registry
docker run -d -p 8091:8091 -p 7091:7091 --network newlead --name seata-serve -e SEATA_IP=192.168.249.132 -v /home/hadoop/seata-sever1.4/seata-server.conf:/seata-server/resources/registry.conf seataio/seata-server:1.4.0 1.5后就是
先运行一个容器,把目录复制出来进行挂载
docker run -d -p 8091:8091 -p 7091:7091 --name seata-serve seataio/seata-server:latest
#拷出后可以,可以选择修改application.yml再cp进容器,或者rm临时容器,如下重新创建,并做好映射路径设置
docker cp seata-serve:/seata-server/resources /User/seata/config
- 指定 application.yml
docker run --name seata-server \-p 8091:8091 \-p 7091:7091 \-e SEATA_IP=宿主机ip \-v /User/seata/config:/seata-server/resources \seataio/seata-server
-
连接不上nacos 或者springcloud连接不上seata,这三个之前
有版本依赖关系如果跨版本就会报错 -
数据库连接失败导致seata无法启动
当你的数据库是8之后,也许你的项目可以使用老驱动连接mysql,但是seata一定会报错,如果报错null指针,就要看看是否需要更换新驱动,并且有seata有些版本需要加时区
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://localhost:3306/seata?useUnicode=true&rewriteBatchedStatements=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
- 在使用seata时候需要在对应服务的库中添加undo_log回调日志表和全局锁表,不然也可能服务事务无法被seata管理
