请教一个 centos6 上安装 gitlab 的问题， gitlab-ctl reconfigure 时报错

安装过程（隐去 ip ）

  929  curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
  931  sudo EXTERNAL_URL="http://113.xxx.xxx.xxx:xxx" yum -y install gitlab-ce

执行后，按照文档，应该已经可以运行了，但是无法访问。

执行 gitlab-ctl status，显示如下内容：

down: postgresql: 1s, normally up, want up; run: log: (pid 22114) 48669s
run: redis: (pid 22115) 48669s; run: log: (pid 22113) 48669s

执行 gitlab-ctl reconfigure，报错如下：

看样子是 postgresql 出的问题，网上查到了一些 kill 掉 postgresql 再重启的方案，尝试了一下，也没有作用。而且 ps aux | grep postgresql 也看不出有 postgresql 的进程：

 ps aux | grep postgresql

请问大家这是怎么回事，对 gitlab 的部署结构不太了解，没思路做进一步分析了
