是否可以将Phusion Passenger升级到更新的版本(在我的情况下使用Nginx)？
我使用passenger-install-Nginx-module安装了Passenger 4.0.0.rc6.我的Nginx配置现在包含
passenger_root /usr/local/lib/ruby/gems/2.0.0/gems/passenger-4.0.rc6;
passenger_ruby /usr/local/bin/ruby;
现在我想升级到Passenger 4.0.2.我可以安装gem,但是当我再次运行passenger-install-Nginx-module时,它会尝试重新编译并重新安装Nginx. (我认为在我使用–prefix指定的位置已经安装了Nginx会非常聪明)
我试图手动将passenger_root更改为新的Passenger gem位置,但是我在Nginx错误日志中收到以下错误：
2013/05/12 12:30:13 [alert] 14298#0: Unable to start the Phusion Passenger watchdog because its executable (/usr/local/lib/ruby/gems/2.0.0/gems/passenger-4.0.2/agents/PassengerWatchdog) does not exist. This probably means that your Phusion Passenger installation is broken or incomplete,or that your 'passenger_root' directive is set to the wrong value. Please reinstall Phusion Passenger or fix your 'passenger_root' directive,whichever is applicable. (-1: Unknown error)
显然,PassengerWatchdog是在运行passenger-install-Nginx-module时构建的.我不想从旧的宝石上复制PassengerWatchdog,因为有些东西可能已经改变了.
最佳答案
@ Wukerplank的评论让我走上正轨.我再次运行passenger-install-Nginx-module时检查了输出,它说：
原文链接：/nginx/435232.htmlNginx doesn't support loadable modules such as some other web servers do,so in order to install Nginx with Passenger support,it must be recompiled.
Do you want this installer to download,compile and install Nginx for you?
1. Yes: download,compile and install Nginx for me. (recommended)
The easiest way to get started. A stock Nginx 1.4.1 with Passenger
support,but with no other additional third party modules,will be
installed for you to a directory of your choice.
2. No: I want to customize my Nginx installation. (for advanced users)
Choose this if you want to compile Nginx with more third party modules
besides Passenger,or if you need to pass additional options to Nginx's
'configure' script. This installer will 1) ask you for the location of
the Nginx source code,2) run the 'configure' script according to your
instructions,and 3) run 'make install'.
Whichever you choose,if you already have an existing Nginx configuration file,then it will be preserved.
重要的是,Nginx必须重新编译才能与Passenger一起使用,并保留现有的Nginx配置.
