pg_ctl: không tìm thấy lệnh, gói nào có lệnh này?


30

Tôi đã cài đặt pgadmin bằng trung tâm phần mềm Ubuntu và đang cố gắng truy cập cơ sở dữ liệu cục bộ (được tải xuống gần đây từ internet). Tôi đã cố chạy lệnh pg_ctl (chạy dưới dạng postgres) tuy nhiên điều này mang lại một lỗi không tìm thấy lệnh. Tôi cũng đã chạy các lệnh sau:

echo $PATH: /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games 

Vì vậy, đó là một chút của một nơi kỳ lạ nhưng vẫn còn. whereis pg_ctl: pg_ctl: /usr/share/man/man1/pg_ctl.1.gz type pg_ctl: -su:Vì vậy, nó ở đâu đó trên hệ thống của tôi type: pg_ctl: not found có vẻ sai

Câu trả lời:

Bạn nên chỉnh sửa đường dẫn của mình:

$ cd ~
$ vim .profile
PATH=$PATH:/usr/lib/postgresql/{version}/bin
export PATH
$ . ~/.profile

Thay thế {version}bằng số phiên bản chính xác.

Và bây giờ bạn có thể thực thi lệnh từ shell:

pg_ctl --help
pg_ctl is a utility to initialize, start, stop, or control a PostgreSQL server.

Có một lý do pg_ctlcho một phiên bản pg cụ thể (ví dụ 9.1, 9.4) không có trong $PATHUbuntu của bạn . Nếu bạn nâng cấp Ubuntu, nhiều phiên bản pg có thể đang chạy và pg_ctlclustersẽ chỉ chăm sóc tất cả chúng. Xem câu trả lời kinh điển hơn của @PeterEisentraut .

Bạn không nên chạy pg_ctltrực tiếp trong Ubuntu / Debian. Sử dụng pg_ctlclusterthay thế, được cài đặt bởi postgresql-common. Xem trang người đàn ông của nó để biết tài liệu.

Nếu bạn không sử dụng versionclustertham số nào bạn nên sử dụng khi gọi pg_ctlcluster, hãy kiểm tra đầu ra của pg_lsclusters.

sử dụng mã này:

sudo pg_ctlcluster 'cluster_version' 'cluster-name' 'action'

Ở đâu:

/etc/postgresql/**cluster-version**/**cluster-name**/start.conf

hành động ở đâu:

start|stop|restart|reload|status|promote

ví dụ mã của tôi:

/etc/postgresql/9.5/main/pg_hba.conf

sudo pg_ctlcluster 9.5 main reload

pg_lscluster cũng hữu ích để tìm ra phiên bản cụm và tên cụm.
