为roundcube添加配置文件后NGINX启动失败

我已经创建了一个在nginx上运行Pelican的web服务器。以下是/etc/nginx/sites available/larryfrits.com中包含的web服务器配置文件：

server {
    server_name www.larryfritts.com;

    # Rewrite www to non-www
    rewrite ^(.*) http://larryfritts.com$1 permanent;
}

server {
    # Listening ports
    listen 80;      ## listen for ipv4; this line is default and implied
    listen [::]:80; ## listen for ipv6

    # Make site accessible from domain
    server_name larryfritts.com;

    # Root directory
    root /var/www/larryfritts.com/public_html;
    index index.html index.htm index.php;

    # Logs
    access_log /var/www/larryfritts.com/logs/access.log;
    error_log /var/www/larryfritts.com/logs/error.log;

    # Includes
    include global/restrictions.conf;
}

一切正常。我决定添加邮件服务器和roundcube，因此为roundcube创建了另一个配置文件。这可以在/etc/nginx/sites available/roundcube中找到：

server {
    server_name mail.larryfritts.com;
        listen 80;
    return 301 https://mail.yourdomain.com$request_uri;
}

server {
    server_name mail.larryfritts.com;
        listen 80;
    return 301 https://$host$request_uri;
}

# HTTPS server
server {
    listen 443 ssl spdy default_server;
    server_name mail.larryfritts.com;
    root /usr/share/nginx/roundcube;
    index index.html index.php;
    autoindex off;

    ssl on;
    ssl_certificate /etc/ssl/private/ssl-chain-mail-larryfritts.pem;
    ssl_certificate_key /etc/ssl/private/ssl-key-decrypted-mail-larryfritts.key;
    ssl_protocols TLSv1.2 TLSv1.1 TLSv1 SSLv3;
    ssl_ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AES:RSA+3DES:!ADH:!AECDH:!MD5:!DSS;
    ssl_prefer_server_ciphers on;
    ssl_ecdh_curve secp521r1;

    # Client auth via certs
#   ssl_client_certificate /etc/ssl/private/yourdomain.crt;
#   ssl_trusted_certificate /etc/ssl/private/yourdomain.crt;
#   ssl_verify_client on;

    location / {
#       if ($ssl_client_s_dn !~* "you@yourdomain.com") {
#           return 301 http://www.jurassicsystems.com/;
#       }
#       error_page 403 @fallback;
    }

    location ~ ^/(README|INSTALL|LICENSE|CHANGELOG|UPGRADING)$ {
        deny all;
    }

    location ~ ^/(bin|SQL)/ {
        deny all;
    }

    location ~ ^/.*\.php {
        try_files $uri =404;
        include fastcgi_params;
        fastcgi_pass php5-fpm-sock;
        fastcgi_param HTTPS on;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors on;
    }

这两个文件均已启用sym链接到/etc/nginx/sites/

当我尝试重新启动nginx时，出现了一个故障：

service nginx restart
 * Restarting nginx nginx        [fail]

---

我假设我的两个配置文件有冲突，但这是我安装的第一台服务器，我还不太了解它。

sudo nginx-t将向您显示错误谢谢。这将我引向正确的方向，我能够确定我需要更新nginx，并且我有一个左括号。我不知道那个把戏，一个档案。
