perl - 未知指令 "perl_modules"

Question

尝试使用以下 /etc/nginx/nginx.conf 设置启动 nginx 时，出现未知指令“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;
}

我安装了 perl:

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)

看起来该模块已在我的 nginx 设置中启用:

root@0f0babe794c4:/etc/nginx# nginx -V
nginx version: nginx/1.9.15

值得注意的是，上面包括--with-http_perl_module=dynamic。

我是否缺少启用此 perl 模块以便设置动态变量的额外步骤？

Answer 1

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

我使用了 --modules-path 选项中的路径，因此请检查此目录以获取 http_perl 模块文件的确切名称
