nginx has a lot of community tripartite module offers many useful features, which are due to the default module does not include a way, is often needed to compile the source code to achieve the purpose of this article to subs_filter example, first tell us about confirmation method tripartite module.
subs_filter module
subs_filter means for replacing the URL, the process of performing forwarding has more common use. Set in the configuration file is generally like this:
subs_filter www.待替换的内容 [mirror_host_name];
subs_filter https:// http://;
That it contains the modules
Method 1: Use nginx -V
[root@liumiaocn nginx]# nginx -V
nginx version: nginx/1.16.1
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled

[root@liumiaocn nginx]#
Confirm that it contains the appropriate module, the direct command may be used to confirm
[root@liumiaocn nginx]# nginx -V 2>&1 |grep subs_filter
[root@liumiaocn nginx]#
The foregoing is an example of the log does not exist, using default nginx mounted at the CentOS yum, and the module will not be installed.
Method 2: acknowledgment / usr / lib64 / nginx / modules directory
/ Usr / lib64 / nginx / modules directory is obtained nginx -V installation directory module, the module will generally constituents present in the form of so files, to check whether the file corresponding to this directory so can be checked
[root@liumiaocn nginx]# ls /usr/lib64/nginx/modules
ngx_http_image_filter_module.so ngx_http_perl_module.so ngx_http_xslt_filter_module.so ngx_mail_module.so ngx_stream_module.so
[root@liumiaocn nginx]#
Method 3: nginx profile is determined by
Add the location to replace the statement in paragraph nginx configuration files, such as the following statement speaks replaced http https
subs_filter https:// http://;
Then perform nginx -s reload to load, if you have this module, you can perform normal, otherwise it will prompt similar to the following log information
[root@liumiaocn nginx]# nginx -s reload
nginx: [emerg] unknown directive "subs_filter" in /etc/nginx/nginx.conf:53
[root@liumiaocn nginx]#
Another example is the following example:
subs_filter http://www.google.com http://IP地址;
subs_filter https://www.google.com http://IP地址;
to sum up
This article describes how to confirm the tripartite module in nginx, the next will continue to introduce how to compile source code and settings.
