重启后自动启动服务器导轨 [英] start rails server automatically after reboot

问题描述

我想我的rails服务器每次重新启动后自动启动，所以我增加了以下到我的.bashrc文件

  RVM 1.9.2使用
CD /家庭/用户/的myapp
轨道服务器
 

就这样，服务器不会自动重新启动后开始，我必须手动启动它。

此外，当我登录到启动服务器，我看到以下消息

 使用/usr/local/rvm/gems/ruby-1.9.2-p290
/usr/local/rvm/rubies/ruby-1.9.2-p290/bin/ruby：符号查找错误：/usr/local/rvm/gems/ruby-1.9.2-p290/gems/sqlite3-1.3.4/ LIB / sqlite3的/ sqlite3_native.so：未定义的符号：sqlite3_initialize
 

因此​​，我需要使用宝石安装sqlite3的后，我让自己超级用户每次重新启动后安装sqlite3的，也只有这样我就可以开始Rails服务器没有问题。

解决方案

安装Apache和乘客

他们将在一个更安全和更系统的方式在服务器启动你的App照顾，什么是现在或多或少的标准。

我不得不使用Rails 4和Ruby 2.1同样的问题在CentOS 6.如果你不熟悉的bash脚本和RC，型材系统 - 它的速度更快，更容易安装乘客。

另外，还有一些其他的原因，你会去的乘客，包括安全和性能（www.phusionpassenger.com）

下面是一个快速如何做的什么了我介绍的宝石。

1. 安装Apache（HTML守护进程）和依赖包（如果没有他们的话）：

   
     

   百胜安装的httpd卷曲DEVEL的httpd-DEVEL

   
   




2. 获得Apache在引导时启动：

   
     

   chkconfig的httpd的上

   
   




3. 安装的Phusion乘客和依赖包：

   
     

   创业板安装客运结果
     百胜安装卷曲DEVEL的httpd-DEVEL

   
   




4. 编译环境：

   
     

   乘客安装-Apache2的模块

   
   




5. 编辑等在Apache的配置文件/的httpd / conf目录/ httpd.conf文件

   
   

   • 取消注释包含行了NameVirtualHost *：80 接近尾声

   
   

   • 在文件的结尾粘贴的任何地方，从4点输出），例如：

   
   

   
     

   的LoadModule passenger_module /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.41/buildout/apache2/mod_passenger.so

   
     
     

   PassengerRoot /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.41

   
     
     

   PassengerDefaultRuby /usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby

    ＆LT;虚拟主机*：80＆GT;
    服务器名称1.2.3.4＃www.whatever.com
    的DocumentRoot的/ var / WWW /导轨/公共＃的路径Rails应用程序
    ＆LT;目录/ var / WWW /导轨/公共＆GT;
    所有的AllowOverride
    选项​​-MultiViews
    ＆LT; /目录＆GT;
   ＆LT; /虚拟主机＆GT;
    

   
   

我花了30分钟，共有包括与httpd.conf中得到的一切权利几个试的错误。

请注意，安装需要你的机器上至少有1 GB RAM。

I'd like my rails server to start automatically after every reboot, so I added the following to my .bashrc file

rvm use 1.9.2
cd /home/user/myapp
rails server

With that, the server never starts automatically after a reboot, and I have to start it manually.

Also, when I login to start the server, I see the following message

Using /usr/local/rvm/gems/ruby-1.9.2-p290
/usr/local/rvm/rubies/ruby-1.9.2-p290/bin/ruby: symbol lookup error: /usr/local/rvm/gems/ruby-1.9.2-p290/gems/sqlite3-1.3.4/lib/sqlite3/sqlite3_native.so: undefined symbol: sqlite3_initialize

As a consequence, I need to install sqlite3 after every reboot using "gem install sqlite3" after I make myself superuser, and only then I can start the rails server without issues.

$ cat /etc/*-release
CentOS release 5.8 (Final)

$ rails -v
Rails 3.1.1

$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]

Anyone can please help me overcome this issue? Thanks

解决方案

Install Apache and Passenger

They will take care of starting your App with the server in a safer and more systematic way and what is now more or less a standard.

I had the same issue with Rails 4, Ruby 2.1 on CentOS 6. If you're not familiar with bash scripts and the rc, profiles system - it's much faster and easier to setup passenger.

Also, there are other reasons why you would go for passenger, including security and performance ( www.phusionpassenger.com )

Here is a quick how-to of what it took me to introduce the gem.

1. Install Apache (html daemon) and dependency packages (if you don't have them already):

   yum install httpd curl-devel httpd-devel

2. Get Apache to start on boot:

   chkconfig httpd on

3. Install Phusion Passenger and dependency packages:

   gem install passenger
   yum install curl-devel httpd-devel

4. Compile the environment:

   passenger-install-apache2-module

5. Edit the Apache config file in etc/httpd/conf/httpd.conf

   • Uncomment the line containing NameVirtualHost *:80 towards the end

   • Paste the output from point 4) anywhere at the end of the file, eg:

   LoadModule passenger_module /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.41/buildout/apache2/mod_passenger.so

   PassengerRoot /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.41

   PassengerDefaultRuby /usr/local/rvm/gems/ruby-2.1.1/wrappers/ruby

   <VirtualHost *:80>
    ServerName 1.2.3.4 # www.whatever.com
    DocumentRoot /var/www/rails/public # the path to your rails app
    <Directory /var/www/rails/public>
    AllowOverride all
    Options -MultiViews
    </Directory>
   </VirtualHost>
   

Took me 30 minutes in total, including several trial-errors with the httpd.conf to get everything right.

Note that installation requires at least 1 GB RAM on your machine.
