需求：hba.changyoufun.com-121.201.125.239（gd1）--hk1--co(alpha*.ggdev.co) 广东代理--->香港--->加拿大
由于idc机房在加拿大，所以经常会配些nginx多级反向代理到国内.(不做代理client就得*，或者说是丢包很严重.)
下面的Nginx配置我只写80的，443的忽略，简化nginx的配置，参数也不一一列举不然太多了.
gd1的反向代理配置:(就是一个反向代理)
cat hba.changyoufun.com.conf
server{
listen 121.201.125.239:80;
server_name hba.changyoufun.com;
access_log /data/weblogs/hba.changyoufun.com.access.log main;
index index.html index.php index.htm;
location / {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_read_timeout 600;
proxy_connect_timeout 600;
proxy_pass http://hba80;
}
}
Upstream配置(代理的是hk1的内网ip):
upstream hba80 {
server 10.105.3.222:80;
}
upstream hba443 {
server 10.105.3.222:443;
}
hk1的反向代理配置:(也是一个nginx反向代理)
cat hba.changyoufun.com.conf
server{
listen 10.105.3.222:80;
server_name hba.changyoufun.com;
access_log /data/weblogs/hba.changyoufun.com.access.log main;
index index.html index.php index.htm;
location / {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
proxy_read_timeout 600;
proxy_connect_timeout 600;
proxy_pass http://hba80;
}
}
Upstream配置(代理的是alpha*.ggdev.co域名的ip地址):
upstream hba80 {
server 216.66.17.34:80;
}
upstream hba443 {
server 216.66.17.34:443;
}
co机房原先已经存在alpha*.ggdev.co域名的配置，只需要copy一份alpha*.ggdev.co的nginx配置，将域名替换为hba.changyoufun.com即可.
co的两份nginx配置:
nginx和php的web版:
cat hba.changyoufun.com.conf
server{
listen 216.66.17.34:80;
server_name hba.changyoufun.com ;
access_log /data/weblogs/hba.changyoufun.com.access.log main;
index index.html index.php index.htm;
root /product/*/alpha/web/htdocs;
location ~ ^/.*(do|php)$ {
fastcgi_pass php_proxy;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
}
cat alpha*.ggdev.co.conf
server{
listen 216.66.17.34:80;
server_name alpha*.ggdev.co;
access_log /data/weblogs/alpha*.ggdev.co.access.log main;
index index.html index.php index.htm;
root /product/*/alpha/web/htdocs;
location ~ ^/.*(do|php)$ {
fastcgi_pass php_proxy;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
}
注释:其实nginx的代理很简单,很多时候是没想明白,既然代理alpha*.ggdev.co，前面两级代理配置了这个域名不就ok了？仔细想发现nginx代理根据ip:端口找域名,然后在location匹配到的location段再找upstream段,再根据upstream段的ip+port找下级域名，最后发现最后一级没有相匹配的域名就报404了,所以最后一层也要配上相匹配的域名配置.
