预先编译好的安装包
Nginx在一些Linux发行版和BSD的各个变种版本的安装包仓库中都会有，通过各个系统自带的软件包管理方法即可安装。需要注意的是，很多预先编译好的安装包都比较陈旧，大多数情况下还是推荐直接从源码编译。

使用源代码进行构建
Nginx 使用 Unix 下常用的 ‘./configure && make && make install’ 过程来编译安装。
configure 脚本确定系统所具有一些特性，特别是 nginx 用来处理连接的方法。然后，它创建 Makefile 文件。
configure 支持下面的选项：
–prefix=
–sbin-path=
–conf-path=
–pid-path=
–lock-path=
–error-log-path=
–http-log-path=
–user=
–group=
–builddir=DIR - 指定编译的目录
–with-rtsig_module - 启用 rtsig 模块
–with-select_module –without-select_module - Whether or not to enable the select module. This module is enabled by default if a more suitable method such as kqueue, epoll, rtsig or /dev/poll is not discovered by configure.
//允许或不允许开启SELECT模式，如果 configure 没有找到更合适的模式，比如：kqueue(sun os),epoll (linux kenel 2.6+), rtsig(实时信号)或者/dev/poll(一种类似select的模式，底层实现与SELECT基本相 同，都是采用轮训方法) SELECT模式将是默认安装模式
–with-poll_module –without-poll_module - Whether or not to enable the poll module. This module is enabled by default if a more suitable method such as kqueue, epoll, rtsig or /dev/poll is not discovered by configure.
–with-http_ssl_module - Enable ngx_http_ssl_module. Enables SSL support and the ability to handle HTTPS requests. Requires OpenSSL. On Debian, this is libssl-dev.
//开启HTTP SSL模块，使NGINX可以支持HTTPS请求。这个模块需要已经安装了OPENSSL，在DEBIAN上是libssl
–with-http_realip_module - 启用 ngx_http_realip_module
–with-http_addition_module - 启用 ngx_http_addition_module
–with-http_sub_module - 启用 ngx_http_sub_module
–with-http_dav_module - 启用 ngx_http_dav_module
–with-http_flv_module - 启用 ngx_http_flv_module
–with-http_stub_status_module - 启用 “server status” 页
–without-http_charset_module - 禁用 ngx_http_charset_module
–without-http_gzip_module - 禁用 ngx_http_gzip_module. 如果启用，需要 zlib 。

–without-http_fastcgi_module - 禁用 ngx_http_fastcgi_module
–without-http_memcached_module - 禁用 ngx_http_memcached_module
–without-http_limit_zone_module - 禁用 ngx_http_limit_zone_module
–without-http_empty_gif_module - 禁用 ngx_http_empty_gif_module
–without-http_browser_module - 禁用 ngx_http_browser_module
–without-http_upstream_ip_hash_module - 禁用 ngx_http_upstream_ip_hash_module
–with-http_perl_module - 启用 ngx_http_perl_module
–with-perl_modules_path=PATH - 指定 perl 模块的路径
–with-perl=PATH - 指定 perl 执行文件的路径
–http-log-path=PATH - Set path to the http access log
–http-client-body-temp-path=PATH - Set path to the http client request body temporary files
–http-proxy-temp-path=PATH - Set path to the http proxy temporary files
–http-fastcgi-temp-path=PATH - Set path to the http fastcgi temporary files
–without-http - 禁用 HTTP server
–with-mail - 启用 IMAP4/POP3/SMTP 代理模块
–with-mail_ssl_module - 启用 ngx_mail_ssl_module
–with-cc=PATH - 指定 C 编译器的路径
–with-cpp=PATH - 指定 C 预处理器的路径
–with-cc-opt=OPTIONS - Additional parameters which will be added to the variable CFLAGS. With the use of the system library PCRE in FreeBSD, it is necessary to indicate –with-cc-opt=”-I /usr/local/include”. If we are using select() and it is necessary to increase the number of file descriptors, then this also can be assigned here: –with-cc-opt=”-D FD_SETSIZE=2048″.
–with-ld-opt=OPTIONS - Additional parameters passed to the linker. With the use of the system library PCRE in FreeBSD, it is necessary to indicate –with-ld-opt=”-L /usr/local/lib”.
–with-cpu-opt=CPU - 为特定的 CPU 编译，有效的值包括：pentium, pentiumpro, pentium3, pentium4, athlon, opteron, amd64, sparc32, sparc64, ppc64
–without-pcre - 禁止 PCRE 库的使用。同时也会禁止 HTTP rewrite 模块。在 “location” 配置指令中的正则表达式也需要 PCRE 。
–with-pcre=DIR - 指定 PCRE 库的源代码的路径。
–with-pcre-opt=OPTIONS - Set additional options for PCRE building.
–with-md5=DIR - Set path to md5 library sources.
–with-md5-opt=OPTIONS - Set additional options for md5 building.
–with-md5-asm - Use md5 assembler sources.
–with-sha1=DIR - Set path to sha1 library sources.
–with-sha1-opt=OPTIONS - Set additional options for sha1 building.
–with-sha1-asm - Use sha1 assembler sources.
–with-zlib=DIR - Set path to zlib library sources.
–with-zlib-opt=OPTIONS - Set additional options for zlib building.
–with-zlib-asm=CPU - Use zlib assembler sources optimized for specified CPU, valid values are: pentium, pentiumpro
–with-openssl=DIR - Set path to OpenSSL library sources
–with-openssl-opt=OPTIONS - Set additional options for OpenSSL building
–with-debug - 启用调试日志
–add-module=PATH - Add in a third-party module found in directory PATH
在不同版本间，选项可能会有些许变化，请总是使用 ./configure –help 命令来检查一下当前的选项列表。
示例 (最好能在同一行)：
./configure \ –sbin-path=/usr/local/nginx/nginx \ –conf-path=/usr/local/nginx/nginx.conf \ –pid-path=/usr/local/nginx/nginx.pid \ –with-http_ssl_module \ –with-pcre=../pcre-4.4 \ –with-zlib=../zlib-1.1.3
Ubuntu/debian 上的示例，需要预先安装 libgcrypt11-dev, libpcre3-dev 和 libssl-dev (选择 –with-md5 或 –with-sha1 中的一个, 但不能都选; 在 debian 和 ubuntu 上, 它们应该都指向 /usr/lib)
./configure --with-openssl=/usr/lib/ssl/ --with-md5=/usr/lib
Ubuntu Edgy 的一个 0.5.2 版本的 .deb 包可以在这里下载: nginx_0.5.2-1_i386.deb.
(注: 根据 October 2006 message 的消息，md5 在一个现在不再使用的 http 缓存模块中用到，而 sha1 用在一个未完成的 mysql 库模块，所以它们当前都不是必须的)

Condign saying thanks settle upon not reasonable be enough, representing the wonderful pellucidity in your writing.
