RVM与瘦用户,root用户和本地用户

更新时间:2023-12-03 23:27:58

RVM带有一个方便的包装生成器,该生成器为init.d脚本创建了一个中间加载器。这使您可以使用特定的Ruby版本和gemset加载服务。我这样使用它(安装瘦宝石后):


1-为瘦创建init.d条目

  sudo薄安装

2-设置一些默认值

  sudo /usr/sbin/update-rc.d -f薄默认值

3-生成您的Rails应用程序的启动配置

  sudo Thin config -C /etc/thin/<appname>.yml -c / var / rails /&lt ; appdir> --servers 4 -e生产

4-生成rvm包装器脚本

  rvm包装器< ruby​​version> @< gemset>启动瘦

5-如果使用的是全局gemset,则只需使用

  rvm包装器ruby-1.9.2-p125启动瘦

6-编辑Thin Init

  sudo nano /etc/init.d/thin 

7-更改原始加载程序

  DAEMON = / usr / local / rvm / gems / ruby​​-< ruby​​version&gt ;-< ruby​​revision> @< gemset> / bin / thin 

8-而是指向rvm包装器

  DAEMON = / usr / local / bin / bootup_thin 

9-启动

  sudo服务瘦启动

如果您要运行多个应用程序,只需为每个应用程序生成一个启动配置yml文件;引导时,将解析/ etc / thin /中的所有yml文件。此处更多信息:

虽然我不再在生产中使用RVM,但薄型仍然是我的生产服务器选择,并且我仍然使用上面的步骤1-3开始。但是它生成的默认配置可以进行一些调整,以下是我的一些调整:


设置用户&精简运行的组为:

 用户:www-data 
组:www-data

删除端口配置并改为使用套接字(快一点):

 #端口:3000 
套接字:tmp / sockets /< appname> .sock

告诉瘦重启实例一个接一个,而不是先关闭它们再重新启动(滚动重新启动):

  onebyone:真

让服务器处理一个标签,以帮助识别它们(在ps aux等中):

 标签:< appname> 


So I'm trying to get thin to run as a service with RVM. After a thin install I manually updated /etc/init.d/thin to use an su - user when running the config command so that thin was running as a local user, rather than root. So far so good.

Now, when I try to sudo service thin start it looks like it's trying to use the non-RVM version of Ruby (1.8.7 which was installed on the box to start with) to actually execute the command. I did a gem install thin on the non-RVM version, which then gets me a uninitialized constant Bundler message—Bundler is only installed in the RVM gems, not the system gems. It looks like I can't get the RVM environment set up (even though my RVM startup script is in ~/.bashrc which is then included in ~/.bash_profile).

All I want to do is run thin as a service using the RVM environment, not the system environment. Is this even possible? Should I just give up and commit the ultimate sin of running everything as root? It's very tempting at this point.

Thanks for any help!

RVM comes with a handy wrapper generator that creates an intermediary loader for an init.d script. This allows you to load a service using a particular Ruby version and gemset. I use it like this (after installing the thin gem):

1 - create init.d entry for thin

sudo thin install 

2 - set up some defaults

sudo /usr/sbin/update-rc.d -f thin defaults 

3 - generate boot config for your rails app

sudo thin config -C /etc/thin/<appname>.yml -c /var/rails/<appdir> --servers 4 -e production

4 - generate rvm wrapper script

rvm wrapper <rubyversion>@<gemset> bootup thin

5 - If you're using a global gemset, you can just use

rvm wrapper ruby-1.9.2-p125 bootup thin

6 - edit thin init

sudo nano /etc/init.d/thin

7 - change the original loader

DAEMON=/usr/local/rvm/gems/ruby-<rubyversion>-<rubyrevision>@<gemset>/bin/thin

8 - to point to the rvm wrapper instead

DAEMON=/usr/local/bin/bootup_thin

9 - start it up

sudo service thin start

If you're running more than one app, just generate a boot config yml file for each one; when booting thin all yml files in /etc/thin/ are parsed. More info here:

2013 BONUS EDIT

While I no longer use RVM in production, thin is still my production server of choice, and I still use steps 1-3 above to get started. But the default configuration it generates can do with a few tweaks, here are some of mine:

Set the user & group that thin runs as:

user: www-data
group: www-data

Remove the port config and switch to using sockets instead (a little faster):

# port: 3000
socket: tmp/sockets/<appname>.sock

Tell thin to restart instances one by one, instead of shutting them all down before starting up again (rolling restart):

onebyone: true

Give the server processes a "tag" to help identify them (in ps aux etc):

tag: <appname>
