Centos7.9上seata一直报以上错误

原因：

seata集群的服务器时间不同步导致，其中有一台与其他延迟1分钟以上，seata默认全局事务超时时间是1分钟。

Linux服务器运行久时，系统时间就会存在一定的误差，一般情况下可以使用date命令进行时间设置，但在做数据库集群分片等操作时对多台机器的时间差是有要求的，此时就需要使用ntpdate进行时间同步

解决：

安装时间同步工具
yum install ntpdate -y

网络时间同步命令；注意：若不加上-u参数， 会出现以下提示：no server suitable for synchronization found
ntpdate -u cn.pool.ntp.org

ntp服务器
cn.pool.ntp.org 中国开源免费NTP服务器
ntp1.aliyun.com 阿里云NTP服务器
ntp2.aliyun.com 阿里云NTP服务器
time1.aliyun.com 阿里云NTP服务器
time2.aliyun.com 阿里云NTP服务器

如果不希望一直手工执行可以添加定时任务，root下执行
crontab -e
复制以下内容，每20分钟执行一次
*/20 * * * * /usr/sbin/ntpdate -u ntp1.aliyun.com >/dev/null &
或者执行
echo "*/20 * * * * /usr/sbin/ntpdate -u ntp1.aliyun.com >/dev/null &" >> /var/spool/cron/root
