使用Phusion Passenger和Rails时,初始服务器启动缓慢

# Speeds up spawn time tremendously -- if your app is compatible. 
# RMagick seems to be incompatible with smart spawning
# Older versions of Passenger called this RailsSpawnMethod
PassengerSpawnMethod smart

# Keep the application instances alive longer. Default is 300 (seconds)
PassengerPoolIdleTime 1000

# Keep the spawners alive, which speeds up spawning a new Application
# listener after a period of inactivity at the expense of memory.
# Older versions of Passenger called this RailsAppSpawnerIdleTime
PassengerMaxPreloaderIdleTime 0

# Just in case you're leaking memory, restart a listener 
# after processing 5000 requests
PassengerMaxRequests 5000

Application fork

Passenger User Guide 是这些和更多配置选项的绝佳参考。

:

# Automatically hit your site when apache starts, so that you don't have to wait
# for the first request for passenger to "spin up" your application. This even
# helps when you have smart spawning enabled. 
PassengerPreStart http://myexample.com/
PassengerPreStart http://myexample2.com:3500/

# the minimum number of application instances that must be kept around whenever 
# the application is first accessed or after passenger cleans up idle instances
# With this option, 3 application instances will ALWAYS be available after the
# first request, even after passenger cleans up idle ones
PassengerMinInstances 3

或者,如果你正在使用智能产卵(推荐) PassengerMaxPreloaderIdleTime 0 PassengerPreStart 以获得立即启动的额外好处。

非常感谢英雄们 phusion.nl !

rails_spawn_method smart;
rails_app_spawner_idle_time 0;
rails_framework_spawner_idle_time 0;
passenger_pool_idle_time 1000;

rails_spawn_method 而是使用

passenger_spawn_method smart; 

到目前为止,其他一切都很好。

http://www.modrails.com/documentation/Users%20guide%20Apache.html#PassengerMinInstances

这可以与PassengerPreStart结合使用

# Additionally keep a copy of the Rails framework in memory. If you're 
# using multiple apps on the same version of Rails, this will speed up
# the creation of new RailsAppSpawners. This isn't necessary if you're
# only running one or 2 applications, or if your applications use
# different versions of Rails.
RailsFrameworkSpawnerIdleTime 0

只是一些补充,可能有用。

框架生成器超时无论如何都不会生效,除非您 显式地将spawn方法设置为“smart”。

如果你的主机是共享服务器,就像我的一样,你无法更改设置,只能执行cron作业。

检查乘客的版本。这是RailsSpawnMethod <string>

如果是这样(如果我没记错的话),请在所有配置指令中将Passenger替换为Rails,或者查找旧的Passenger文档以获取更多详细信息
