nginx搭建笔记

1. nginx安装

Env: Mac OS 10.10 Yosemite

pcre: http://pcre.org/

$tar -zxf pcre-8.34.tar.gz
$cd pcre-8.34
$./configure
$make 
$sudo make install

zlib: http://zlib.net/

$tar -zxf zlib-1.2.8.tar.gz
$cd zlib-1.2.8
$./configure
$make
$sudo make install

openssl: http://www.openssl.org/source/

$tar -zxf openssl-1.0.1j.tar.gz
$cd openssl-1.0.1j
$./config

注意下此时会有提示要编译64位版本需要用另外的指令

WARNING! If you wish to build 64-bit library, then you have to

         invoke './Configure darwin64-x86_64-cc' *manually*.

         You have about 5 seconds to press Ctrl-C to abort.

$make clean
$./Configure darwin64-x86_64-cc
$make
$sudo make install

nginx: http://nginx.org/en/download.html

$tar -zxf nginx-1.7.8.tar.gz
$cd nginx-1.7.8
$./configure --with-http_ssl_module
$make
$sudo make install

安装完毕，/usr/local/nginx为服务器安装目录

$cd /usr/local/nginx
$ls
conf html logs sbin

conf为服务器配置目录，编辑nginx.conf启用各种模块

html为网站文件目录，存放html/js/css等文件

sbin为nginx可执行文件，

$./sbin/nginx -h
nginx version: nginx/1.7.8
Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /usr/local/nginx/)
  -c filename   : set configuration file (default: conf/nginx.conf)
  -g directives : set global directives out of configuration file

启动nginx服务器： sudo /usr/local/nginx/sbin/nginx

这时候打开浏览器输入http://localhost/能显示Welcome to nginx!表示配置成功

停止、重启等操作通过-s参数，例如修改配置后重启：sudo /usr/local/nginx/sbin/nginx -s reload

 2. nginx启用gzip压缩

参数设置可参考http://www.cnblogs.com/dasn/articles/4043989.html

其中gzip_types可参照nginx/conf/mime.types的映射进行设置，比apache方便不少

例如：

gzip  on;
gzip_types text/plain text/html text/xml application/javascript application/json;
gzip_comp_level 4;
gzip_http_version 1.0;

3. nginx缓存时间控制

expires [time|epoch|max|off]

默认off

time: 可为正负数，负数表示永远过期

epoch: 指定为1 January, 1970, 00:00:01 GMT

max: 指定为31 December 2037 23:59:59 GMT

例如：

location ~ \.(jpg|ico|png|jpeg|js|json|html|txt)$ {
            expires 30d;
        }
