I executed the following commands:docker stop doris-be;docker stop doris-fe;docker start doris-fe;docker start doris-be;
docker stop doris-be;
docker stop doris-fe;
docker start doris-fe;
docker start doris-be;

如下是be.conf的配置后面三行都是重启自动写的，每重启一次写一行

基础端口

be_port = 9060
webserver_port = 8040
heartbeat_service_port = 9050
brpc_port = 8060

双SSD存储路径

storage_root_path = /opt/apache-doris/be/storage_hdd1,medium:hdd;/opt/apache-doris/be/storage_ssd1,medium:ssd;/opt/apache-doris/be/storage_ssd2,medium:ssd

sys_log_dir = /opt/apache-doris/be/log
log_level = WARN

内存配置
