Rails App Maintenence Without Hindering Visitors

阅读更多关于 Rails App Maintenence Without Hindering Visitors

问题 A Phusion Passenger error message isn't what I want my visitors to see if they landed on my site while I'm updating the back end. So how do I get around this? Is my deployment process flawed from the start? or is there something I'm missing out? Here's my process of deployment, so you get the picture: commit new updates to a git repo and push to remote cap deploy ssh [ip] rake gems:install rake db:migrate cucumber The time in between the cap deploy and the db:migrate or gems:install is when

问题 I'm trying to deploy my first rails app on a mediatemple (dv) and i'm not having any luck. I'm trying to use phusion passenger so i went over to http://www.modrails.com/videos/passenger.mov and watched the tutorial on installing this. I did everything with no issues and I'm when i point to my ip, i see an apache page and not my rails app. I noticed that on mediatemple, I had to create a vhosts.conf file and run a command to reconfigure my project to look at this vhosts.conf file.

Rails app moved to production server gives “dump format error for symbol” error

阅读更多关于 Rails app moved to production server gives “dump format error for symbol” error

I've just moved my rails app from the development to deployment server. I've installed passenger, but I wanted to try with rails s to make sure all was running fine (this is the first time I develop and deploy a rails application). Specs are: Ruby 1.9.3 with RVM, mod_passenger, Rails 3.2.3. All installed correctly and I've also enabled the Apache module. By the way something is going wrong (passenger keeps sayng "Error message: Unknown key: class".) Running rails s is giving a weird error listed above dump format error for symbol(0x45) Processing by Devise::SessionsController#new as HTML

问题 I am trying to run the passenger-install-apache2-module command and I keep getting this error: ext/apache2/mod_passenger.c:25:10: fatal error: 'httpd.h' file not found Not sure what happened to it, my local dev environment was fine until I upgraded to Mavericks - I had to update XCode and uninstall/reinstall the passenger gem. I tried creating httpd.h in the /etc/apache2 directory and pasting this in but that didn't work. I've no idea how to replace this file 回答1: I was having the same error.

I have the latest Nginx running with Passenger, SQLite and Rails 3.1. Somehow, when I have Passenger running for a while, I start getting "502 bad gateway" errors when visiting my website. Here is a snippet from my Nginx error log: 2011/06/27 08:55:33 [error] 20331#0: *11270 upstream prematurely closed connection while reading response header from upstream, client: xxx.xxx.xx.x, server: www.example.com, request: "GET / HTTP/1.1", upstream: "passenger:unix:/passenger_helper_server:", host: "example.com" 2011/06/27 08:55:47 [info] 20331#0: *11273 client closed prematurely connection, so upstream

How does RVM work in production with no users logged in?

阅读更多关于 How does RVM work in production with no users logged in?

问题 Considering putting RVM into production (light duty) on a new machine. But I'm not visualizing how it will work if a user isn't logged in. RVM has been installed into /usr/local/rvm/bin/rvm so it is available to "everyone". If server restarts and is at login screen and background daemons are serving apache/rails, etc. and no .bashrc , etc. have loaded...how/where do we specify which of RVM's Rubies to load? Perhaps somewhere in Phusion's Passenger? who manages these gemsets? are they shared?

Gitlab in a subdirectory with apache and passenger

阅读更多关于 Gitlab in a subdirectory with apache and passenger

问题 I'm attempting to set up gitlab so that it is accessible through a subdirectory of an existing apache server, example.com/gitlab , for example. I am trying to use passenger, as this seems to be the easiest to set up, but other solutions would also be acceptable. Using a separate virtual host for gitlab is unfortunately not an option for me. My Setup In setting this up, I have followed the gitlab setup guide and the passenger documentation. I believe the most relevant parts of /etc/httpd/conf

When to restart and not reload Nginx?

阅读更多关于 When to restart and not reload Nginx?

问题 When is it necessary to restart nginx and reload will not suffice? Does it make a difference if an extension like passenger is used? Should the service be restarted if it consumes too much memory. Any other reasons for restarting Nginx, particularly after a configuration change either in an extension or a Nginx core config? After making a configuration change, one can either restart or reload nginx, via the binary itself or the init.d script "/etc/init.d/nginx -h" on Ubuntu. Which method
