在OCP上修改了单机集群上面两个参数后，OCP中重启集群发现启动不了，有什么方法可以重新启动？下面是服务器上的报错日志

集群是ocp部署的还是obd部署的 ob版本号查一下
SHOW VARIABLES like ‘version_comment’;

AntTech_RFKTWX · 2025 年11 月 26 日 18:02

OCP单机部署的，ob版本 4.4.0

zhenxing · 2025 年11 月 26 日 18:04

可以命令行启OBServer试试，路径和参数配置大小根据实际情况调整

su - admin
cd /home/admin/oceanbase/bin
./observer -o "system_memory=4G,memory_limit=10G"

AntTech_RFKTWX · 2025 年11 月 26 日 18:11

只加这两个参数，进程启动不了

可以看看这个博客的分析应该是参数设置的不合理导致的
看看通过命令行启动看看能不能拉起来

AntTech_RFKTWX · 2025 年11 月 26 日 18:41

谢谢了，通过如下命令确实手工启动了，然后OCP又能监测到了
cd /home/admin/oceanbase && /home/admin/oceanbase/bin/observer -I 192.168.56.110 -P 2882 -p 2881 -z zone1 -d /home/admin/oceanbase/store/obcp -r ‘192.168.56.110:2882:2881’ -c 10001 -n obcp -o “memory_limit=6G,system_memory=1G,__min_full_resource_pool_memory=1073741824”

学习了，涨知识

淇铭 · 2025 年11 月 27 日 18:10

ocp的版本号能在发一下么？看看ocp是哪个版本

AntTech_RFKTWX · 2025 年11 月 27 日 22:18

您好，我下载的是ocp-all-in-one-4.4.0-20251114143405.el7.x86_64.tar.gz

alvin-zhang · 2025 年11 月 29 日 17:43

这两个信息能方便在查一下么？
