Nginx 是一個高性能的 HTTP 和 反向代理服務器，也是一個 IMAP/POP3/SMTP 代理服務器。Nginx 編譯安裝比較簡單，難點在於配置
優點：
支持高達 50,000 個併發連接數的響應，Nginx爲我們選擇了 epoll and kqueue作爲開發模型。
Nginx作爲負載均衡服務器：Nginx 既可以在內部直接支持 Rails 和 PHP 程序對外進行服務，也可 以支持作爲 HTTP代理服務器對外進行服務。Nginx採用C進行編寫，不論是系統資源開銷還是CPU使用效率都比 Perlbal 要好很多。
作爲郵件代理服務器：Nginx 同時也是一個非常優秀的郵件代理服務器
Nginx 是一個安裝非常的簡單，配置文件非常簡潔（還能夠支持perl語法），Bugs非常少的服務器：Nginx 啓動特別容易，並且幾乎可以做到7*24不間斷運行，即使運行數個月也不需要重新啓動。你還能夠不間斷服務的情況下進行軟件版本的升級。
step 1 模塊依賴性
yum -y install gcc openssl-devel pcre-devel zlib-devel
step 2 編譯安裝
groupadd nginx useradd -g nginx -s /bin/false -M nginx tar -zxf nginx-1.8.0.tar.gz cd nginx-1.8.0 ./configure \ --prefix=/usr \ --sbin-path=/usr/sbin/nginx \ --conf-path=/etc/nginx/nginx.conf \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --pid-path=/var/run/nginx/nginx.pid \ --lock-path=/var/lock/nginx.lock \ --user=nginx \ --group=nginx \ --with-http_ssl_module \ --with-http_flv_module \ --with-http_stub_status_module \ --with-http_gzip_static_module \ --http-client-body-temp-path=/var/tmp/nginx/client/ \ --http-proxy-temp-path=/var/tmp/nginx/proxy/ \ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ make && make install makdir -p /var/log/nginx
