PostgreSQL 服务器启动失败，无法创建锁定文件：权限被拒绝

Question

每当我使用安装它时，我都试图安装和运行 postgreSQL 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？ 我正在运行 Ubuntu 13.10

Answer 1

更改/var/run/postgresql的所有者并将其设置为postgres ：

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

如果您运行的用户没有 sudo 权限，则

1. 更改为根：

    su -

2. 将/var/run/postgresql所有权更改为用户postgres和组postgres ：

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

我在 Ubuntu 14.04 上安装postgres时遇到了同样的问题，更改所有权为我解决了这个问题。

Answer 2

锁定文件最终在/var/run 。 为了修复这个目录的权限，我需要运行sudo chmod a+w /var/run/postgresql 。

Answer 3

你能检查/var/run的文件权限吗？

ls -l /var/run

如果缺少“写”权限，请尝试

sudo chmod o+w /var/run
