PostgreSQL服务器无法启动,无法创建锁定文件:权限被拒绝

Question

我试图安装并运行postgreSQL服务器,每当我使用它安装它

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; 我该怎么解决呢？我正在运行Ubuntu 13.10

Answer 1

检查/ var/run/postgresql的所有者并将其设置为postgres(如果尚未设置).为此,请键入

sudo chown -R postgres:postgres /var/run/postgresql

如果您正在运行的用户没有sudo权限,那么

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时遇到同样的问题,更改所有权为我解决了问题.

Answer 2

锁定文件最终进入/var/run.要修复此目录的权限,我需要运行sudo chmod a+w /var/run/postgresql.

Answer 3

你能检查一下/var/run的文件权限吗？

ls -l /var/run

如果缺少“写入”权限，请尝试

sudo chmod o+w /var/run
