postgresql 出现 Is the server running locally and accepting connections on Unix domain socket “/var/run/postgresql/.s.PGSQL.5432”?

有可能/var/lib/postgresql 文件夹权限被无意中更改

解决方案1:

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

来源: http://ubuntuforums.org/showthread.php?t=2257724

解决方案2:

原因解释: http://askubuntu.com/questions/50621/cannot-connect-to-postgresql-on-port-5432

sudo ln -s /tmp/.s.PGSQL.5432 /var/run/postgresql/.s.PGSQL.5432 #创建软连接

sudo vim /etc/postgresql/9.4/main/pg_hba.conf #修改配置文件

将 local all postgres peer 中的peer

local all postgres turst

netstat -nlp | grep 5432 ##查看是否成功

推荐第二种,第一种成功一次 ,但第二天还是出现同样的问题。

在psql进入数据库 出现 以下错误 [postgres@pg data]$ psql psql: could not connect to server : No such file or directory Is the server running local ly and accep ting connection s on Unix dom ain socket "/tmp/.s.PGSQL.54 $ psql -h 10.0.4.13 -U postgres -d postgres -p5432 psql: error: could not connect to server : Connection refused Is the server running on host "10.0.4.13" and accep ting TCP/IP connection s on... (4)修改postgres数据库监听 socket 目录(这一步 非必须步骤,使用默认的/tmp/.s.PGSQL.5432也可以,使用默认的/tmp/.s.PGSQL.5432时,直接用psql就能登录,不用加参数h来指定 socket 监听位置),相关目录需要给权限。psql -h /tmp/postgrev15_ socket /.s.PGSQL.5432 (修改了 socket 监听的目录,故登录时需要制定 socket )(6)用test用户使用 socket 连接数据库。(1)首先在数据库中创建一个test用户。 Is the server running on host " local host" (::1) and accep ting TCP/IP connection s on port 5432? could not connect to server : Connection refused Is the server running on host "127.0.0.1" and accep ting TCP/IP connection s on port 5432? 无法连接到服务器:连接被拒绝服务器是否在主. 错误提示: psql: could not connect to server : No such file or directoryIs the server running local ly and accep ting connection s on Unix dom ain socket "/ var /run/ postgresql /.s.PGSQL.5432"? 出现 该问题的很... 1、问题描述 在修改 postgresql .conf文件中" unix _ socket _directories" 值时,重启数据库生效,但是必须制定 -h /xx/xx来使用 the Unix dom ain socket 连接数据库。 测试如下: [wln@ local host postgres9.3]$ cat data/ postgresql .conf | grep unix _ socket <!--google_ad_client = "pub-5873492303276472";/* 728x90, 创建于 08-7-29 */google_ad_slot = "7502041044";google_ad_width = 728;google_ad_height = 90;// --><!--google_ad_client = "p 执行psql时遇到, connection to server on socket "/ var /run/ postgresql /.s.PGSQL.5432" failed。 could not connect to server : Connection refused (0x0000274D/10061) Is the server running on host" local host"(::1)and accep ting TCP/IP connection on port 5434?.. 打开 postgresql 输入密码连接不上报错 这种情况大概率是数据库没有启动 启动一下就好了 打开任务管理器-----服务----找到 postgresql 服务-----右键开始 然后重开p $ psql postgres psql: error: could not connect to server : could not connect to server : No such file or directory Is the server running local ly and accep ting connection s on Unix dom ain socket "/ var /run/ postgresql /.s.PGSQL.5432 cd / var /lib/cloudera-scm- server -db/data/ [root@ambari server pg_log]# service cloudera-scm- server -db restart wai ting for se 完整报错如下: django.db.utils.OperationalError: could not connect to server : Connection refused Is the server running on host " local host" (127.0.0.1) and accep ting TCP/IP connection s on por...
