base_path			存儲和日誌文件的基礎路徑（必須配置項）
max_connections	256		最大連接數
accept_threads	1		接收線程數量
work_threads	4		工作線程數量，工作線程數量應該 <= 最大連接數
store_lookup	0	0：輪詢，1:指定分組,2:負載均衡，選擇空閒空間最大的分組上傳文件	定義如何選擇分組進行文件上傳
store_group			應該上傳到哪個分組 ，當 store_lookup 配置爲1時，必須設置分組名字
store_server	0	0：輪詢，1: 按照IP排序的第一臺服務器，2：按照優先級排序的第一臺服務器順序（最小）	向哪個存儲服務上傳文件
store_path	0	0:輪詢，1:負載均衡，選擇空閒空間最大的路徑上傳文件	存儲服務器上載文件的路徑(磁盤或掛載點)。
download_server	0	0:輪詢，1: 當前文件上傳到的源存儲服務器	要從哪裏下載文件
reserved_storage_space			爲系統或其他應用程序保留的存儲空間。如果組中任何存儲服務器的可用（可用）空間<= reserved_storage_space，則無法將任何文件上載到該組。字節單位可以是以下之一：G或g（GB），M或m（兆字節），K或k表示千字節（KB），字節（B）沒有單位XX.XX％作爲比率，例如reserved_storage_space = 10％
run_by_group			運行該程序的Unix組名，未設置（空）表示由當前用戶組運行。
run_by_user			運行該程序的Unix用戶名，未設置（空）表示當前用戶運行。
allow_hosts	*		“ allow_hosts”可以出現多次，host可以是主機名或IP地址，“ *”表示匹配所有ip地址，可以使用以下範圍：10.0.1。[1-15,20]或host [01-08， 20-25] .domain.com，例如：allow_hosts = 10.0.1。[1-15,20] , allow_hosts = host [01-08,20-25] .domain.com

trunk_init_check_occupying	false		裝載行李箱空閒空間時是否檢查行李箱空間佔用。佔用的空間將被忽略。注意：將此參數設置爲true會在啓動時減慢中繼空間的加載速度。您應在必要時將此參數設置爲true。
trunk_init_reload_from_binlog	false		如果忽略storage_trunk.dat，請從中繼binlog重新加載。當版本低於V3.10時，一次設置爲true即可進行版本升級。
