问题描述
每当我使用以下方法安装PostgreSQL服务器时，我都会尝试安装和运行该服务器
sudo apt-get install postgresql
我收到以下错误：
* Starting PostgreSQL 9.1 database server
* The PostgreSQL server failed to start. Please check the log output:

我猜这是一个权限问题；我该如何解决呢？我正在运行Ubuntu 13.10
最佳方法
检查/var /run /postgresql的所有者并将其设置为postgres(如果尚未这样做)，请键入
sudo chown -R postgres:postgres /var/run/postgresql
如果您所运行的用户没有sudo特权，则
1)更改为root
su -
2)将/var /run /postgresql的所有权更改为postgres用户和postgres组
chown -R postgres:postgres /var/run/postgresql
在Ubuntu 14.04上安装postgres并更改所有权后，我遇到了同样的问题，从而为我解决了这个问题。
次佳方法
锁定文件最终位于/var/run中。要修复此目录的权限，我需要运行sudo chmod a+w /var/run/postgresql。
