方法一：sudo apt-get install nginx nginx-module-njs
方法二：cd到nginx源包的根目录下 cd /root/nginx-1.19.2/
执行nginx -V
复制那一串代码出来，那后在后面添加 –with-stream=dynamic
例如我的是这样：

./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf 
--error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid
 --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp 
--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp
 --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio
 --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module
 --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module
 --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module
 --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module
 --with-stream_ssl_preread_module --with-cc-opt='-g -O2 -fdebug-prefix-map=/data/builder/debuild/nginx-1.19.1/debian/debuild-base/nginx-1.19.1=. -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -Wl,--as-needed -pie'
 --add-module=../ngx_brotli --with-openssl=../openssl-1.1.1d --with-openssl-opt=enable-tls1_3 --with-stream=dynamic

make编译 ，切记不要install
当前目录objs中会存在 编译好的 ngx_stream_module.so
执行cp ngx_stream_module.so nginx_worker_dir/modules/

nginx.conf配置中加上

load_module modules/ngx_stream_module.so;

systemctl reload nginx，没报错就好了
