Linux&nbspNginx服务器怎么样实现网站不区分大小写

如果你将跑在Windows下的项目（如：php）迁移到Linux下，由于Windows操作系统中，文件名是不区分大小写的；而Linux系统是大小写敏感，会导致有些网页出现404情况。

解决方法有大概4种：

1、 url rewrite

2、 perl模块

3、 lua模块

4、 ngx_http_lower_upper_case

????第一种方法适用于有规则的或者较少的url需要转换，如果有大量并无规则的请用下面几种方法

????第二、三、四种方法前提是Linux系统本地文件是小写，原理是将url请求转换成小写来处理

????perl模块（不推荐！Nginx官网已申明perl模块存在内存漏洞的可能），方法如下（《lnmp一键安装包》安装后执行下面）：

cd lnmp/src/nginx-1.4.4

make clean #清除已经编译出的nginx

# /usr/local/nginx/sbin/nginx -V #获取已编译参数

nginx version: nginx/1.4.4

built by gcc 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)

TLS SNI support enabled

configure arguments: –prefix=/usr/local/nginx –user=www –group=www –with-http_stub_status_module –with-http_ssl_module –with-http_flv_module –with-http_gzip_static_module –with-ld-opt=\’-ljemalloc\’

????在已经编译的参数后面加上 –with-http_perl_module ，如下：

./configure –prefix=/usr/local/nginx –user=www –group=www –with-http_stub_status_module \\

–with-http_ssl_module –with-http_flv_module –with-http_gzip_static_module –with-ld-opt=\’-ljemalloc\’ \\

–with-http_perl_module

????可能会报如下错误：

Can\’t locate ExtUtils/Embed.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .).

BEGIN failed–compilation aborted.

./configure: error: perl module ExtUtils::Embed is required

????解决方法（CentOS）：

yum -y install perl-devel perl-ExtUtils-Embed

????再次编译：

make clean

./configure –prefix=/usr/local/nginx –user=www –group=www –with-http_stub_status_module \\

–with-http_ssl_module –with-http_flv_module –with-http_gzip_static_module –with-ld-opt=\’-ljemalloc\’ \\

–with-http_perl_module

make

cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx$(date +%m%d) #备份nginx原文件

service nginx stop

make install #直接安装，如果只覆盖nginx，会有报错

/usr/local/nginx/sbin/nginx -t

修改配置主文件（/usr/local/nginx/conf/nginx.conf）：

perl_set $url \’

sub {

my $r = shift;

my $re = lc($r->uri);

return $re;

}

\’;

修改虚拟主机配置文件（如：/usr/local/nginx/conf/vhost/demo.linuxeye.com.conf）：

if ($uri ~ [A-Z]){

rewrite ^(.*)$ $url last;

}

lua模块（推荐！）

lua-nginx-module来自大牛agentzh的开源项目，在Nginx中嵌入Lua语言，使之可以支持强大Lua语法，如下：

cd lnmp/src

wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz

wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz #ngx_devel_kit

wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.9.2.tar.gz #nginx_lua_module

tar xzf LuaJIT-2.0.2.tar.gz

tar xzf v0.2.19.tar.gz

tar xzf v0.9.2.tar.gz

cd LuaJIT-2.0.2

make && make install

export LUAJIT_LIB=/usr/local/lib

export LUAJIT_INC=/usr/local/include/luajit-2.0

cd nginx-1.4.4

make clean #清除已经编译出的nginx

# /usr/local/nginx/sbin/nginx -V #获取已编译参数

nginx version: nginx/1.4.4

built by gcc 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)

TLS SNI support enabled

configure arguments: –prefix=/usr/local/nginx –user=www –group=www –with-http_stub_status_module –with-http_ssl_module –with-http_flv_module –with-http_gzip_static_module –with-ld-opt=\’-ljemalloc\’

重新编译Nginx：

./configure –prefix=/usr/local/nginx –user=www –group=www –with-http_stub_status_module \\

–with-http_ssl_module –with-http_flv_module –with-http_gzip_static_module –with-ld-opt=-ljemalloc \\

–add-module=../lua-nginx-module-0.9.2 –add-module=../ngx_devel_kit-0.2.19

make
