以添加echo-nginx-module模块为例

查看现有nginx的编译参数

$ nginx -V
nginx version: nginx/1.20.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --user=nginx --group=nginx --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/usr/local/nginx/logs/error.log --http-log-path=/usr/local/nginx/logs/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-http_v2_module --with-http_realip_module

下载模块

cd /usr/local/nginx/modile

git clone https://github.com/openresty/echo-nginx-module.git

进入原编译文件夹，加上模块参数再编译

$ cd nginx-1.20.2/
$ ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf --error-log-path=/usr/local/nginx/logs/error.log --http-log-path=/usr/local/nginx/logs/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-pcre --with-http_v2_module --with-http_realip_module --add-module=/usr/local/nginx/modile/echo-nginx-module
$ make #千万千万不能 make install ；否则会把之前已经安装的nginx 覆盖掉

备份原有已安装好的nginx

mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak

把新的nginx程序拷贝进来

cp objs/nginx /usr/local/nginx/sbin/

验证并重启新程序

$ nginx -V
nginx version: nginx/1.20.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017

echo-nginx-module模块的用法

方便测试，可以用来打印

location /test {
        index index.html;
        default_type text/html;
        echo "hello world,main-->";
        echo_reset_timer;
        echo_location /sub1;
        echo_location /sub2;
        echo "took $echo_timer_elapsed sec for total.";
}
location /sub1 {
        echo_sleep 1;
        echo sub1;
}
location /sub2 {
       echo_sleep 1;
       echo sub2;
}
