初始化环境什么配置？看上面贴出来的日志没有看出来报错的原因呢。

#4

是这个问题 。就是i没有生成这个文件 。

cd /home/wuhs/oceanbase; /home/wuhs/oceanbase/bin/observer -r ‘127.0.0.1:2882:2881’ -p 2881 -P 2882 -z ‘zone1’ -n ‘obtest’ -c 1 -d ‘/ocdata’ -i ‘lo’ -l ‘INFO’ -o __min_full_resource_pool_memory=268435456,memory_limit=‘1G’,system_memory=‘1G’,stack_size=‘512K’,cpu_count=16,cache_wash_threshold=‘1G’,workers_per_cpu_quota=10,schema_history_expire_time=‘1d’,net_thread_count=4,sys_bkgd_migration_retry_num=3,minor_freeze_times=10,enable_separate_sys_clog=0,enable_merge_by_turn=False,datafile_size=‘5G’,enable_syslog_wf=False,enable_syslog_recycle=True,max_syslog_file_count=4

这里的 memory_limit 设置的调小了，目前最小需要8G
