出现如下错误时：
Could not found property service.disableGlobalTransaction, try to use default value instead

控制台错误才会消失

启动命令  ：
指定文件存储方式开启（不指定默认也是文件存储《存储在》）
sh seata-server.sh -p 8091 -m file

如果出现如下情况：
[root@iZm5e3d7te8727xoyd0vhdZ bin]# sh seata-server.sh -p 8091  -m file

尤其是红色那一句说明内存不充足了

使用free -m /free -g 可以查看内存大小
