使用http://openresty.org/的包，裏面包含了lua模塊

yum -y install pcre-devel openssl openssl-devel

./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-luajit

添加
chkconfig --add nginx

Nginx -s stop 快速關閉Nginx，可能不保存相關信息，並迅速終止web服務。（quick exit）
Nginx -s quit 平穩關閉Nginx，保存相關信息，有安排的結束web服務。（graceful exit）
Nginx -s reload 因改變了Nginx相關配置，需要重新加載配置而重載。（changing configuration，start a new worker,quitting an old worker gracefully.)
Nginx -s reopen 重新打開日誌文件。(reopenging log files)

nginx -s reload
當主進程收到重新加載配置的信號後，它先檢測新配置的語法是否規範，然後開始嘗試加載新的配置。如果上面的步驟成功，主進程開始啓動新的工作進程並且發停止信號給舊的工作進程；否則，主進程回滾到改變前的配置，並繼續使用舊的配置工作。舊的工作進程接受到停止工作信號，它停止接受新的連接請求，但繼續處理當前的請求知道這些請求被處理完成。最後，舊的工作進程退出。

nginx -s quit
停止nginx但等待工作進程處理完成當前的請求
