Linux 伺服器部署 PgAdmin 4 Server
阿新 • • 發佈:2018-11-23
PostgreSQL 使用率越來越高,但是好用的圖形化軟體,諸如 Navicat、DataGrip、HeidiSQL 都是客戶端軟體,對於訪問控制來說,比起 MySQL 的 phpMyAdmin 更加麻煩。與 pma 對標的 phpPgAdmin 自 2013 年停更,並且不支援 PostgreSQL 10,非常尷尬。好在 PgAdmin 4 提供了 Server Deploy 選項。本文以 Ubuntu Linux 為例子,提供一個 PgAdmin 4 Server 的部署案例。
安裝 pip 安裝包:
sudo apt-get install build-essential libssl-dev libffi-dev libgmp3-dev virtualenv python-pip libpq-dev python-dev
更新軟體
sudo apt-get update
sudo apt-get dist-upgrade
安裝 virtualenv 虛擬環境
sudo pip install virtualenvwrapper
virtualenv pgadmin4
cd pgadmin4/
source bin/activate
下載 PgAdmin4 原始碼包
最新的原始碼包在 https://www.postgresql.org/ftp/pgadmin/pgadmin4/
請從這裡獲取下載地址。
下面的程式碼是以 3.5 為藍本。
wget https://ftp.postgresql.org/pub/pgadmin/pgadmin4/v3.5/source/pgadmin4-3.5.tar.gz tar xf pgadmin4-3.5.tar.gz cd pgadmin4-3.5/
安裝依賴庫
sudo apt-get install libpq-dev
pip install -r requirements.txt
安裝 PgAdmin4
python web/setup.py
這裡不出意外會報一個錯:
Traceback (most recent call last): File "web/setup.py", line 15, in <module> from pgadmin.model import db, Version, SCHEMA_VERSION as CURRENT_SCHEMA_VERSION File "/root/pgadmin4/pgadmin4-3.5/web/pgadmin/__init__.py", line 33, in <module> from pgadmin.utils.session import create_session_interface, pga_unauthorised File "/root/pgadmin4/pgadmin4-3.5/web/pgadmin/utils/session.py", line 26, in <module> import config File "/root/pgadmin4/pgadmin4-3.5/web/config.py", line 121, in <module> if builtins.SERVER_MODE is None: AttributeError: 'module' object has no attribute 'SERVER_MODE'
總而言之,因為沒有 SERVER_MODE
屬性導致 Crash。查閱原始碼:
# The server mode determines whether or not we're running on a web server
# requiring user authentication, or desktop mode which uses an automatic
# default login.
#
# DO NOT DISABLE SERVER MODE IF RUNNING ON A WEBSERVER!!
#
# We only set SERVER_MODE if it's not already set. That's to allow the
# runtime to force it to False.
#
# NOTE: If you change the value of SERVER_MODE in an included config file,
# you may also need to redefine any values below that are derived
# from it, notably various paths such as LOG_FILE and anything
# using DATA_DIR.
if builtins.SERVER_MODE is None:
SERVER_MODE = True
else:
SERVER_MODE = builtins.SERVER_MODE
因為我們就是 Server Deploy,直接 SERVER_MODE = True
就行。刪除這幾行,然後替換為:
SERVER_MODE = True
後再來一次 python web/setup.py
,按提示輸入郵箱地址和密碼。
執行 PgAdmin4
python web/pgAdmin4.py
輸出:
Starting pgAdmin 4. Please navigate to http://localhost:5050 in your browser.
只能本機訪問,埠是5050。官方提供的方案是用 Apache 做 RP。如果嫌麻煩,在 web
目錄下建立 config_local.py
:
from config import *
DEFAULT_SERVER = '0.0.0.0'
DEFAULT_SERVER_PORT = 9527
再次執行 PgAdmin4 即可通過 9527 埠直接訪問了:
Starting pgAdmin 4. Please navigate to http://0.0.0.0:9527 in your browser.
