building ngx_cache_purge module on CentOS Linux release 7.9.2009 (Core)

[Kaushal Shriyan]

Hi Sergey,

I followed
https://www.nginx.com/blog/compiling-dynamic-modules-nginx-plus/#load_module
to generate the third party dynamic module

Nginx Version :- nginx version: nginx/1.20.1
OS Version :- CentOS Linux release 7.9.2009 (Core)

cd /home/kaushal/ngx-cache-purge/
# ls -l

-rw-r--r-- 1 root root 51501 May  8 02:48 ngx_cache_purge_module.c

# cat config
if [ "$HTTP_PROXY" = "YES" ]; then
    have=NGX_HTTP_PROXY . auto/have
fi

if [ "$HTTP_FASTCGI" = "YES" ]; then
    have=NGX_HTTP_FASTCGI . auto/have
fi

if [ "$HTTP_SCGI" = "YES" ]; then
    have=NGX_HTTP_SCGI . auto/have
fi

if [ "$HTTP_UWSGI" = "YES" ]; then
    have=NGX_HTTP_UWSGI . auto/have
fi

if test -n "$ngx_module_link"; then
    ngx_module_type=HTTP
    ngx_module_name=ngx_http_cache_purge_module
    ngx_module_srcs="$ngx_addon_dir/ngx_cache_purge_module.c"

    have=NGX_CACHE_PURGE_MODULE . auto/have

    . auto/module
else
    HTTP_MODULES="$HTTP_MODULES ngx_http_cache_purge_module"
    NGX_ADDON_SRCS="$NGX_ADDON_SRCS $ngx_addon_dir/ngx_cache_purge_module.c"

    have=NGX_CACHE_PURGE_MODULE . auto/have

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

#nginx -t -c /etc/nginx/nginx.conf
nginx: [emerg] module
"/usr/lib64/nginx/modules/ngx_http_cache_purge_module.so" version 1020002
instead of 1020001 in
/usr/share/nginx/modules/ngx-http-cache-purge-module.conf:1
nginx: configuration file /etc/nginx/nginx.conf test failed

Please correct and guide me if I am missing something. Thanks in advance.

Best Regards,

Kaushal
