相關說明:node
官方建議unicorn['worker_processes']該值是等於CPU核心數+1,能夠提升服務器的響應速度,若是內存只有4G,或者服務器上有其它業務,就不要改了,以避免內存不足。另外,這個參數最小值是2,設爲1服務器可能會卡死,但若是您的內存已消耗太高,請根據業務自行調整,好比8G內存建議您調整4左右,優化是持續性的工做。 如下是官方翻譯過來的內容: CPU 1核心CPU最多支持100個用戶,全部的workers和後臺任務都在同一個核心工做這將致使GitLab服務響應會有點緩慢。 2核心 支持500用戶,這也是官方推薦的最低標準。 4 核心支持2,000用戶。 8 核心支持5,000用戶。 16 核心支持10,000用戶。 32 核心支持20,000用戶。 64 核心支持40,000用戶。 若是想支持更多用戶,可使用集羣式架構 Memory 安裝使用GitLab須要至少4GB可用內存(RAM + Swap)! 因爲操做系統和其餘正在運行的應用也會使用內存, 因此安裝GitLab前必定要注意當前服務器至少有4GB的可用內存. 少於4GB內存會致使在reconfigure的時候出現各類詭異的問題, 並且在使用過程當中也常常會出現500錯誤. 1GB 物理內存 + 3GB 交換分區 是最低的要求,但咱們 強烈反對 使用這樣的配置。 查看下面unicorn worker章節獲取更多建議。 2GB 物理內存 + 2GB 交換分區 支持100用戶,但服務響應會很慢。 4GB 物理內存 支持100用戶,也是 官方推薦 的配置。 8GB 物理內存 支持 1,000 用戶。 16GB 物理內存 支持 2,000 用戶。 32GB 物理內存 支持 4,000 用戶。 64GB 物理內存 支持 8,000 用戶。 128GB 物理內存 支持 16,000 用戶。 256GB 物理內存 支持 32,000 用戶。 若是想支持更多用戶,可使用集羣式架構 即便你服務器有足夠多的RAM, 也要給服務器至少分配2GB的交換分區。 由於使用交換分區能夠在你的可用內存波動的時候下降GitLab出錯的概率。 注意: Sidekiq的25個workers在查看進程(top或者htop)的時候會發現它會單獨顯示每一個worker,可是它們是共享內存分配的,這是由於Sidekiq是一個多線程的程序。 詳細內容查看下面關於Unicorn workers 的介紹。
