Postgresql啓動失敗

-1

psql（PostgreSQL）9.5.5 對不起我的英文版。Postgresql啓動失敗

無法連接到數據庫。

嘗試連接：

psql -h localhost -p 5432 -U postgres -W 
Password for user postgres: 
psql: could not connect to server: Connection refused 
    Is the server running on host "localhost" (127.0.0.1) and accepting 
    TCP/IP connections on port 5432?

在我的postgresql.conf我有聽所有= '*' 和端口5432

須藤netstat的-pant | grep的Postgres的 - 沒有任何顯示

而且

[email protected] ~ # sudo systemctl start postgresql 
[email protected] ~ # sudo su - postgres -c psql 
psql: could not connect to server: No such file or directory 
    Is the server running locally and accepting 
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

後重新啓動檢查狀態

這是一個新的羣集，你剛剛從備份中恢復，是否崩潰？細節，細節！ – Doug

這是舊的postgres，我無法刪除數據並安裝新的。 –

，我沒有看到postgres在PS或頂部 –

我想看看在/ var /日誌，看它是否寫了日誌。

如果沒有，我會嘗試手動啓動它的數據庫：

su - postgres 
postgres -d 5 -D /var/db/postgres/data96

的-d命令5套調試到5級-D命令告訴那裏的PostgreSQL數據庫文件。上述目錄是PostgreSQL 9.6在FreeBSD上運行的位置。如果你正在運行Ubuntu，那麼該目錄應該是/ var/lib/postgresql/[PostgreSQL版本]/data /。 PostgreSQL的默認數據目錄是/ usr/local/pgsql/data。

日誌添加到問題（這是數據庫運行的最後日期）我有Ubuntu的。 LS /var/lib/postgresql/9.5/main 基全球pg_clog裏pg_commit_ts pg_dynshmem pg_logical pg_multixact pg_notify pg_replslot pg_serial pg_snapshots pg_stat pg_stat_tmp pg_subtrans \t pg_tblspc關聯pg_twophase \t PG_VERSION pg_xlog裏面postgresql.auto.conf postmaster.opts 沒有文件夾數據 –

和我不'沒有命令postgres –

/usr/lib/postgresql/9.5/bin/psql –
