我的服务器同时部署啦homeland和redmine,redmine访问无压力,很快,但是homenald就经常卡死, 配置ubuntu16.04, 4核8gb,使用的是nginx+passenger, 不要问我为什么用论坛做文章, 我也很无奈.

建议尝试 puma

passenger 怎么配置的

42thcoder 回复

passenger.conf

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/local/rvm/gems/ruby-2.4.2/wrappers/ruby;

nginx.conf

passenger_default_user xxx;
include /etc/nginx/passenger.conf;

卡死是怎么个卡死?描述更细致一些

我估计是 Action Cable 你没配置对,你可以试试把那个屏蔽了

huacnlee 回复

因为现在在上内容,大量上内容后,大概20篇左右就会卡住,内存占用居高不下

huacnlee 回复

我就是这样想的,如果还找不到解决方式,就直接吧cable屏蔽了

pathbox 回复

嗯,谢谢,再尝试下

并不慢,已经屏蔽Action Cable了?
