手动部署单机版Oceanbase：
执行如下命令：
[admin@ecs-9351 oceanbase]$ cd /home/admin/oceanbase && /home/admin/oceanbase/bin/observer -I 192.168.18.164 -P 2882 -p 2881 -z zone1 -d /home/admin/oceanbase/store/obdemo -r ‘192.168.18.164:2882:2881’ -c 10001 -n obdemo -o “system_memory=30G,datafile_size=200G,config_additional_dir=/data/1/obdemo/etc3;/data/log1/obdemo/etc2”

这个地方是关键，你服务器的内存是多大。。看你system_memory都给了30G，怕是内存不足

system_memory给2G，再重启试试
system_memory是给500租户用的，memory_limit才是给分配给ob的内存，system_memory可以调小一点
