Apache-2.2
優化阿帕奇
我一直在閱讀 apache 的多個優化指南，發現了很多數據（雖然我不知道作者的經驗是什麼）。
我有一個帶有 apache 2.2.3、MySQL 5.1.36、Centos 5.3、nginx 的生產伺服器來充當反向代理伺服器（並處理靜態文件）。
我的主要問題是我有大約 10 個 httpd 程序，每個程序佔用 56-60MB RAM，每 15 分鐘我通過 crond 啟動 10 個 php 程序（每個程序也佔用 30MB）。
基本上我使用預設的 httpd.conf 操作（是的，我知道，這很糟糕），我剛剛調整了 MPM 最大客戶端和其他屬性來控制應該分叉的客戶端數量，並安裝了 nginx 以減少 apache 的負載。
我很高興我可以對我的 httpd 做什麼樣的優化（我知道我應該解除安裝很多模組，但我有點害怕刪除某些東西可能會破壞我的應用程序）。

使用預設的 http.conf（或非常接近它）實際上通常是一件好事。你會驚訝於這個 apache 開發人員和 redhat 工程師比我們大多數人要好得多 :)
首先，如果這聽起來很愚蠢，我深表歉意，但是您確定 nginx 是在apache*前面配置的嗎？*我無法告訴你有多少次我看到人們閱讀了一篇推薦 nginx 的部落格文章，然後將他們現有的 apache 設置為 mod_proxy /images 回到 nginx。
其次，大多數 apache 模組，尤其是 redhat/centos 建構中的模組，都非常適合使用共享庫和 apr 執行時，因此它們不太可能讓你買太多評論它們。
我認為您可能想要查看的最大的東西是 php op 記憶體。它可以對 php 腳本的性能和突發記憶體使用產生巨大影響。幸運的是，作為 CentOS 使用者，您可以設置 EPEL 儲存庫和“yum install php-pecl-apc”並立即進行設置。看看這有什麼幫助。
