本文提供数据库安装脚本，有部分需要优化，就是脚本中的方法执行存在前后依赖，但是代码里面没有对上一个执行结果进行判断，如果提供的路径和安装包没有问题，脚本能够正常执行 1 #!/bin/bash 2 # install postgre 3 # base_path=$(cd $(dirname ${BASH_SOURCE[0]}); pwd ) 4 base_path="/opt" 5 # Pg database installation package name 6 pg_name="./postgresql-9.6.15-1-linux-x64-binaries.tar.gz" 7 # Pg database installation path 8 pg_deploy_path="$base_path/postgreSQL" 9 # Directory of data stored in the pg database 10 pg_data_path="${pg_deploy_path}/data" 11 # Directory of data stored in the pg database 12 user_name='pguser' 13 14 15 # unzip pg 16 function pg_untar(){ 17 if [ -d ${pg_deploy_path}

connection.select_value only returns strings in postgres with pg gem

问题 I'm converting a rails app from using mysql (mysql2 gem) to postgres (pg gem). With mysql, ActiveRecord::Base.connection.select_value calls return values typed according to the data, for example: > ActiveRecord::Base.connection.select_value("SELECT COUNT(*) FROM errors") => 86 > ActiveRecord::Base.connection.select_value("SELECT exception FROM errors where id=565") => "TechTalk.Genome.SqlExecutionException" > ActiveRecord::Base.connection.select_value("SELECT id FROM errors where id=565") =>

gem install pg doesn't work on OSX Lion

由 自作多情 提交于 2019-11-27 05:09:33
问题 There are variations of this question bouncing around SO, but none of them seem to have an answer that solves my problem. I am running OSX Lion (10.7.3). The latest XCode is installed. I've installed Postgres using the Postgres.app package from postgresapp.com. But when I try to install the pg gem, I get a failure: $ gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config Building native extensions. This could take a while... ERROR: Error installing pg:

Trying to set up postgres for ror app, getting error - fe_sendauth: no password supplied

由 为君一笑 提交于 2019-11-27 00:36:57
问题 Getting: An error has occurred: Error connecting to the server: fe_sendauth: no password supplied Settings in database.yml are the same as the app setup on other machines. How can I set things up so that I don't need a password hardcoded? I can view the db ok using PgAdmin-III. I'd rather not have the password in database.yml as other machines using this app don't have/need it, so it seems likely to be something about my Pg install. 回答1: You need to change your change your pg_hba.conf .
