一、 查看nacos.log 日志 （最下面有nacos 集群配置）
出现提示 ，将可能内存栈溢出， 刚开始没有特别注意这个。（其实这个就是主要原因，服务器内存不足。。。。。。蛋疼的提示语）。
后面该 start.sh 里面的空间配置，依旧启动不起来。

以下是调试的时候的截图。---- 就是先检查 服务器磁盘是否充足。
这是 nacos.log 日志。

复习一下 nacos 配置。 可以用集群启动一台服务器~
1. 配置nacos本身数据库 application.properties
2.配置集群机器，cp cluster.conf cluster.conf.example
3. 配置启动参数 startup.sh 修改里面的配置。 其实不用改也可以启动 ，但是你可以改造一下。
（sh startup.sh -m standalone） 单机启动。 默认的是集群启动
或者在\bin下修改startup.cmd文件中的set MODE="standalone"，使之默认为单机方式
启动 ./startup.sh -o 8848 可以 添加命令参数的方式启动指定端口。传送门-----Nacos在企业生产中如何使用集群环境？ - 哔哩哔哩
4. 这时可以直接观察日志：tail -f /usr/local/nacos/nacos/logs/start.out
