摘要：表示指定安裝路徑表示的可執行文件存放路徑表示的主配置文件存放路徑，允許使用不同的配置文件啟動，通過命令行中的選項表示文件的存放路徑，將存儲的主進程的進程號。安裝完成后，可以隨時改變的文件名，在配置文件中使用指令。

--prefix表示指定安裝路徑
--sbin-path表示nginx的可執行文件存放路徑
--conf-path表示nginx的主配置文件存放路徑，nginx允許使用不同的配置文件啟動，通過命令行中的-c選項
--pid-path表示nginx.pid文件的存放路徑，將存儲的主進程的進程號。安裝完成后，可以隨時改變的文件名 ， 在nginx.conf配置文件中使用 PID指令。默認情況下，文件名 為prefix/logs/nginx.pid
--error-log-path表示nginx的主錯誤、警告、和診斷文件存放路徑
--http-log-path表示nginx的主請求的HTTP服務器的日志文件的存放路徑
--user表示nginx工作進程的用戶
--group表示nginx工作進程的用戶組
--with-select_module或--without-select_module表示啟用或禁用構建一個模塊來允許服務器使用select()方法
--with-poll_module或--without-poll_module表示啟用或禁用構建一個模塊來允許服務器使用poll()方法
--with-http_ssl_module表示使用https協議模塊。默認情況下，該模塊沒有被構建。建立并運行此模塊的OpenSSL庫是必需的
--with-pcre表示pcre的源碼路徑
--with-zlib表示zlib的源碼路徑
--with-openssl表示openssl庫的源碼路徑
