Nginx转发多个二级域名及前后端分离
一、直接上代码（以下配置方案为亲在广州某物联网公司做架构时的配置）
/etc/nginx/conf.d/ssl.conf 配置文件：
其中sink-node1与web-node1为内部服务器的hostname。
#
# HTTPS server configuration
server {
listen 443;
server_name localhost;
ssl on;
root html;
index index.html index.htm;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
### Required configuration. ###
proxy_set_header HOST $host;

# subproject为其中一个子系统(前后端分离)的二级域名转发配置
# 以下逻辑为Nginx支持“与”、“或”、“非”等运算符的实现，See: https://www.jianshu.com/p/15a5cf8369f9
set $eff_flag 'EFF';
if ($host = 'subproject.yourdomain.com' ) {
set $eff_flag '${eff_flag}F';

# 关键此，这专门使用nginx来处理前端分离的静态资源，而不是转发到nodejs/webpack服务
# subproject static resource forwarding.
if ($eff_flag ~* 'EFFF' ) {

# Other pan parsing by cid.

}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
/etc/nginx/conf.d/static.conf 配置文件：
其中58888端口专为 子系统subproject开放的静态资源端口，其实就是代替nodejs的web服务。
#
# HTTP front/static server configuration
server {
# The port that is transferred to the front end and the end is not open to the external network.
listen 58888;
server_name localhost;
location / {
# Fixed format (if additional front and back end separation items should be configured in this format),
# both root and index instructions are necessary, because the static file of the project will be under
# the directory of the root instruction, otherwise it will not be loaded..
root /usr/share/nginx/html/efficiency-front;
index index.html;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;

}
