jak*_*119 10 nginx node.js meteor
我知道多个node.js,我通过扩展Meteor,可以使用Nginx在一台服务器上运行.我已经安装了Nginx并在Ubuntu服务器上运行就好了,我甚至可以让它响应请求并将它们代理到我的一个应用程序.然而,当我试图让Nginx将流量代理到第二个应用程序时,我遇到了障碍.
一些背景:
我的Nginx配置:
upstream mydomain.com {
server 127.0.0.1:8001;
server 127.0.0.1:8002;
}
# the nginx server instance
server {
listen 0.0.0.0:80 default_server;
access_log /var/log/nginx/mydomain.log;
location /app2 {
rewrite /app2/(.*) /$1 break;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:8002;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:8001;
proxy_redirect off;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}

任何有关流量进入/ app2时可能会发生什么的见解/我会非常感激!
jmi*_*gov 27
proxy_pass http://127.0.0.1:8002/1; <-- these should be
proxy_pass http://**my_upstream_name**; <--these

然后
upstream my_upstream_name {
//Ngixn do a round robin load balance, some users will conect to / and othes to /app2
server 127.0.0.1:8001;
server 127.0.0.1:8002;
}

一些提示控制代理:
看看这里 @nginx docs
然后我们走了:
weight = NUMBER - 设置服务器的权重,如果没有设置权重等于1.不平衡默认循环.
max_fails = NUMBER - 在一段时间内(由参数fail_timeout指定)与服务器通信失败的次数,之后认为它不起作用.如果未设置,则尝试次数为1.值为0将关闭此检查.被认为是失败的是由proxy_next_upstream或fastcgi_next_upstream定义的(除了不计入max_fails的http_404错误之外).
fail_timeout = TIME - 必须发生的时间*max_fails*与服务器通信失败的次数导致服务器被视为无效的次数,以及服务器被视为无效的时间(在进行另一次尝试之前) ).如果未设置,则时间为10秒.fail_timeout与上游响应时间无关,使用proxy_connect_timeout和proxy_read_timeout来控制它.
down - 将服务器标记为永久脱机,与指令ip_hash一起使用.
备份 - (0.6.7或更高版本)仅在非备份服务器全部关闭或忙碌时才使用此服务器(不能与指令ip_hash一起使用)
EXAMPLE generic
upstream my_upstream_name {
server backend1.example.com weight=5;
server 127.0.0.1:8080 max_fails=3 fail_timeout=30s;
server unix:/tmp/backend3;
}
// proxy_pass http://my_upstream_name;

这些是你需要的:
如果你只是想控制一个应用程序的vhost之间的负载:
upstream my_upstream_name{
server 127.0.0.1:8080 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8081 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8082 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8083 backup;
// proxy_pass http://my_upstream_name;
// amazingness no.1, the keyword "backup" means that this server should only be used when the rest are non-responsive

如果您有2个或更多应用程序:每个应用程序上游1个,如:
upstream my_upstream_name{
server 127.0.0.1:8080 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8081 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8082 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8083 backup;
}
upstream my_upstream_name_app2 {
server 127.0.0.1:8084 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8085 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8086 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8087 backup;
}
upstream my_upstream_name_app3 {
server 127.0.0.1:8088 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8089 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8090 max_fails=3 fail_timeout=30s;
server 127.0.0.1:8091 backup;
