PostgreSQL服务器无法启动,无法创建锁定文件:权限被拒绝

, ,

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
