尝试使用以下/etc/nginx/nginx.conf设置启动nginx时，出现unknown directive "perl_modules"错误：
user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; perl_modules perl/lib; perl_set $subdomain_uppercase 'sub { my $r = shift; my $subdomain = $r->subdomain; $subdomain = uc($subdomain); return $subdomain; }'; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; }
我有Perl安装：
root@0f0babe794c4:/etc/nginx# perl -v This is perl 5, version 20, subversion 2 (v5.20.2) built for x86_64- linux-gnu-thread-multi (with 92 registered patches, see perl -V for more detail)
它看起来像我的nginx设置中启用模块：
root@0f0babe794c4:/etc/nginx# nginx -V nginx version: nginx/1.9.15 built by gcc 4.9.2 (Debian 4.9.2-10) built with OpenSSL 1.0.1k 8 Jan 2015 TLS SNI support enabled configure arguments: --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-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_perl_module=dynamic --add-dynamic-module=debian/extra/njs-1c50334fbea6/nginx --with-threads --with-stream --with-stream_ssl_module --with-http_slice_module --with-mail --with-mail_ssl_module --with-file-aio --with-ipv6 --with-http_v2_module --with-cc-opt='-g -O2 -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-z,relro -Wl,--as-needed'
值得注意的是，上面包括--with-http_perl_module=dynamic 。
我错过了一个额外的步骤，让这个Perl模块启用，所以我可以设置dynamicvariables？
您将ngx_http_perl_module安装为动态模块（ --with-http_perl_module=dynamic ），因此您需要在nginx.conf的开头加载此模块：
load_module /usr/lib/nginx/modules/ngx_http_perl_module.so
我已经使用了路径--modules-path选项，因此请检查此目录以获取http_perl模块文件的确切名称
