nginx编译安装WEB站点内容过滤功能模块(with-http_sub_module)

最近有个需求:需要过滤替换掉网站上部分内容,查了下资料NGINX自带过滤功能模块,于是实践了下,具体操作如下:

虽然是NGINX自带了with-http_sub_module模块,但是需要编译安装NGINX,并指定选项才可以正常使用。

需要编译安装NGINX(with-http_sub_module):


./configure \
--prefix=/application/nginx-1.6.3 \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_stub_status_module \
--without-http_gzip_module \
--with-http_sub_module

译安装NGINX:(ngx_http_substitutions_filter_module)
此模块需要先单独下载
下载地址:git clone git://github.com/yaoweibin/ngx_http_substitutions_filter_module.git

./configure \
--prefix=/application/nginx-1.6.3 \
--user=nginx \
--group=nginx \
--with-http_ssl_module \
--with-http_stub_status_module \
--without-http_gzip_module \
--with-http_sub_module \
--add-module=/application/ngx_http_substitutions_filter_module #指定模块路径

测试过程:建立测试站
配置文件如下:
[root@k8s conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
sub_filter nginx apache;
server {
listen 80;
server_name www.nginx.com;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}


多站点测试:建立vhosts目录(多站点配置incule vhosts/*导入)

Bbs.conf :
server {
listen 80;
server_name bbs.nginx.com;
location / {
root /data/wwwroot/bbs;
index index.html index.htm;
}
}
Blogs.conf:
server {
listen 80;
server_name blogs.nginx.com;
location / {
root /data/wwwroot/blogs;
index index.html index.htm;
}
}


[root@k8s conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
subs_filter nginx apache;
subs_filter If apache;
subs_filter com cn;
subs_filter_types ;
include vhosts/
;
server {
listen 80;
server_name www.nginx.com;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}

访问测试效果:

测试结果:1、sub_filter只支持单行,功能有限(加多行会报错)。
2、subs_filter支持多行过虑,且支持正则,功能较强大。
