nginx - Linode CentOS7 安装gitlab-ce 提示成功，但无法访问

在centos7上安装gitlab-ce，官方教程 https://about.gitlab.com/downloads/#centos7
安装之前系统已经配有 lnmp。
安装到最后一步，提示信息如下：

Running handlers:
Running handlers complete
Chef Client finished, 204/230 resources updated in 79.974115421 seconds
gitlab Reconfigured!
[root@linode ~]# 
[root@linode ~]# 

但查看firewalld 提示如下，未启动：

[root@linode ~]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
   Active: failed (Result: timeout) since 一 2015-11-09 23:25:07 CST; 4min 57s ago
 Main PID: 3837
   CGroup: /system.slice/firewalld.service

11月 09 23:25:07 linode systemd[1]: firewalld.service operation timed out. Terminating.
11月 09 23:25:07 linode systemd[1]: Failed to start firewalld - dynamic firewall daemon.
11月 09 23:25:07 linode systemd[1]: Unit firewalld.service entered failed state.
[root@linode ~]# 

现在提示安装成功，可如何web访问？nginx的配置里面也并没有 gitlab的配置：

[root@linode nginx]# whereis nginx
nginx: /usr/sbin/nginx /etc/nginx /usr/share/nginx
[root@linode nginx]# find /etc/nginx/
/etc/nginx/

很悲催，现在发现ssh无法登录了。IP可以ping得通。

Operation timed out

重启linode可以登录了，但网站变成了gitlab的了。

[root@linode vhost]# find / -name nginx.conf
