按官方提示：
通常情况下 memory_limt/3 ≤ system_memory ≤ memory_limt/2
yaml改为
memory_limt 10G
system_memory 4Gz
一样的结果，

服务器CPU 16X2 共32核心
内存4X8G 共32G
是不是多核服务器不能用mini-single模式？
mini-single.yaml 配置如下
oceanbase-ce:
servers:
# Please don’t use hostname, only IP can be supported
- 192.168.1.3
global:
# The working directory for OceanBase Database. OceanBase Database is started under this directory. This is a required field.
home_path: /root/observer
# The directory for data storage. The default value is $home_path/store.
# data_dir: /data
# The directory for clog, ilog, and slog. The default value is the same as the data_dir value.
# redo_dir: /redo
# Starting from observer version 4.2, the network selection for the observer is based on the ‘local_ip’ parameter, and the ‘devname’ parameter is no longer mandatory.
# If the ‘local_ip’ parameter is set, the observer will first use this parameter for the configuration, regardless of the ‘devname’ parameter.
# If only the ‘devname’ parameter is set, the observer will use the ‘devname’ parameter for the configuration.
# If neither the ‘devname’ nor the ‘local_ip’ parameters are set, the ‘local_ip’ parameter will be automatically assigned the IP address configured above.
# devname: eth0
mysql_port: 2881 # External port for OceanBase Database. The default value is 2881. DO NOT change this value after the cluster is started.
rpc_port: 2882 # Internal port for OceanBase Database. The default value is 2882. DO NOT change this value after the cluster is started.
obshell_port: 2886 # Operation and maintenance port for Oceanbase Database. The default value is 2886. This parameter is valid only when the version of oceanbase-ce is 4.2.2.0 or later.
zone: zone1
cluster_id: 1
# please set memory limit to a suitable value which is matching resource.
memory_limit: 10G # The maximum running memory for an observer
system_memory: 4G # The reserved system memory. system_memory is reserved for general tenants. The default value is 30G.
datafile_size: 2G # Size of the data file.
datafile_next: 2G # the auto extend step. Please enter an capacity, such as 2G
datafile_maxsize: 20G # the auto extend max size. Please enter an capacity, such as 20G
log_disk_size: 14G # The size of disk space used by the clog files.
cpu_count: 16
production_mode: false
enable_syslog_wf: false # Print system logs whose levels are higher than WARNING to a separate log file. The default value is true.
max_syslog_file_count: 4 # The maximum number of reserved log files before enabling auto recycling. The default value is 0.
# root_password: # root user password, can be empty

/data/obdata/sstable/block_file,权限问题？

围观学习~
权限755，root，应不是权限问题。
我在其他桌面电脑麒麟系统安装，没有出现这种问题。
没出现过这个问题，是不是还是资源不足啊，OB很吃资源的，你这个CPU和内存都怎么配置的
cpu 32核心，内存32G
yaml配置：
memory_limit: 10G
system_memory: 4G
cpu_count: 16
是按intel版本安装的麒麟v10 sp1
内存cpu分配的没问题。需要提供一份obd详细日志 cd ~/.obd/log下

Failed to start 127.0.0.1 observer启动异常问题。
cpu是什么架构的 如果是x86指令集需要avx

谢谢指导，
我安装的intel版X86 麒麟系统，安装检测失败，observer.log日志显示，读写clog没有权限报错，
换海光版麒麟系统就没有这个报错了，看来是CPU架构的问题。
