一、概述
使用Nginx要在同一个域名下配置多个项目有两种方式：
a. nginx按不同的目录分发给不同的项目；
b. 启用二级域名，不同的项目分配不同的二级域名。
二、nginx按不同的目录分发给不同的项目
nginx.conf配置部分：
server {
listen 80;
server_name example.com;
location ^~ /project1/ {
proxy_pass http://localhost:8081/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ^~ /project2/ {
proxy_pass http://localhost:8082/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location / {
proxy_pass http://localhost:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
这里配置了三个项目：
http://example.com/project1路径分发到http://localhost:8081/
http://example.com/project2路径分发到http://localhost:8082/
其他路径分发到http://localhost:8080
关键点：
location ^~ /project2/
project2前后都要加斜杠，否则域名映射有问题。
proxy_pass http://localhost:8082/;
路径最后加斜杠：映射的是http://localhost:8082；
路径最后不加斜杠：映射的是http://localhost:8082/project2。
实际应用中，根据需要选择。
完整nginx.conf：
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 8089;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
#root html;
#index index.html index.htm;
}
location ^~/jwt/ {
proxy_pass http://172.20.8.186:8080/;
proxy_set_header Host $host;
#proxy_cookie_path /jwt / ;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
location ^~/home/ {
proxy_pass http://localhost:8082/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
三、启用二级域名，不同的项目分配不同的二级域名
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://localhost:8080;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
#project1
server {
listen 80;
server_name project1.example.com;
location / {
proxy_pass http://localhost:8081;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
#project2
server {
listen 80;
server_name project2.example.com;
location / {
proxy_pass http://localhost:8082;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
说明：
域名example.com映射到http://localhost:8080;
域名project1.example.com映射到http://localhost:8081;
域名project2.example.com映射到http://localhost:8082;
注意：通过代理后，访问域名就可以访问到对应的项目。
四、如何选择
如果是单独子应用，有足够的域名可用，推荐使用第二种方式。测试环境，推荐使用第一种方式。
