我正在一个unknown directive "perl_modules"尝试用下面的启动nginx的错误时/etc/nginx/nginx.conf设定:

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 …

尝试将CA Cert导入我的Java 6信任库，并遇到此错误：

./keytool -v -import -trustcacerts -alias Rapidssl -file /Users/spurr/Desktop/rapidssl.cer -keystore /System/Library/Java/Support/CoreDeploy.bundle/Contents/Home/lib/security/cacerts
Enter keystore password:

我也以root用户身份运行该命令，因此我认为我可以访问该cacerts密钥库位置。使用Java 6。

我有一个属性希望在 a 中是可选的，belongs_to因为用户不必立即属于团队。

class User < ActiveRecord::Base
  belongs_to :team, optional: true
end

team_id未传入的情况下创建的用户：
