请问中控机的配置是怎么样的？看日志报错是 out of memory 了

Download blackbox_exporter:v0.12.0 (linux/amd64) … Done fatal error: runtime: out of memory

使用的虚拟机，配置如下：

我看内存是够的

GongchuangSu · 2020 年6 月 5 日 10:13

虚拟机内存由1G调整为2G后，再重试，截图如下：

内存占用确实很高

先前内存溢出的错暂时没有了，但出现了新的报错

中控机跟TiDB集群部署服务器是同一台服务器导致的。。。需要分开才行！

再弄个新的虚拟机用于TiDB集群，问题解决

注意：需要设置中控机跟TiDB集群部署服务器之前的SSH无密码登陆

比如服务器A与服务器B之间ssh需要无密码登陆，可按照以下步骤进行配置：

在服务器A和B上生成各自的SSH密钥和公钥

# 一路Enter即可
# 生成的密钥和公钥保存在~/.ssh目录下
ssh-keygen -t rsa

将各自SSH公钥上传至对方服务器上

# 在服务器A上执行
ssh-copy-id root@B服务器IP
# 在服务器B上执行
ssh-copy-id root@A服务器IP
