1).gcc:nginx編譯依賴gcc環境
安裝命令：yum install gcc-c++
2).pcre:(Perl Compatible Regular Expressions)是一個Perl庫，包括 perl 相容的正則表示式庫。nginx的http模組使用pcre來解析正則表示式.
安裝命令：yum install -y pcre pcre-devel
3).zlib：該庫提供了很多種壓縮和解壓縮的方式，nginx使用zlib對http包的內容進行gzip。
安裝命令：yum install -y zlib zlib-devel
4).openssl:一個強大的安全套接字層密碼庫，囊括主要的密碼演算法、常用的金鑰和證書封裝管理功能及SSL協議，並提供豐富的應用程式供測試或其它目的使用。nginx不僅支援http協議，還支援https（即在ssl協議上傳輸http）.
安裝命令：yum install -y openssl openssl-devel
