PostgreSQL 服務器啟動失敗，無法創建鎖定文件：權限被拒絕

Question

每當我使用安裝它時，我都試圖安裝和運行 postgreSQL 服務器

sudo apt-get install postgresql

我收到以下錯誤：

* Starting PostgreSQL 9.1 database server                                       
* The PostgreSQL server failed to start. Please check the log output:

我猜這是一個權限問題； 我該如何解決？ 我正在運行 Ubuntu 13.10

Answer 1

更改/var/run/postgresql的所有者並將其設置為postgres ：

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

如果您運行的用戶沒有 sudo 權限，則

1. 更改為根：

    su -

2. 將/var/run/postgresql所有權更改為用戶postgres和組postgres ：

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

我在 Ubuntu 14.04 上安裝postgres時遇到了同樣的問題，更改所有權為我解決了這個問題。

Answer 2

鎖定文件最終在/var/run 。 為了修復這個目錄的權限，我需要運行sudo chmod a+w /var/run/postgresql 。

Answer 3

你能檢查/var/run的文件權限嗎？

ls -l /var/run

如果缺少“寫”權限，請嘗試

sudo chmod o+w /var/run
