1、Nginx的常用配置大家可以去搜一下，有很多优秀的博客，我这篇文章要实现的需求是：
a.根据访问的域名不同，跳转到不同的项目（html首页，80端口）
b.拦截访问中所有带有api的请求，转发到后端的不同服务器中（Tomcat项目，任意端口）
2、下面是Nginx的nginx.conf配置文件
user root root;
worker_processes 1;
#worker_cpu_affinity 1;
worker_rlimit_nofile 60000;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid /var/run/nginx.pid;
events {
use epoll;
worker_connections 60000;
}
http {
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
sendfile on;
tcp_nopush on;
keepalive_timeout 120;
server_tokens off;
tcp_nodelay on;
#ws
# map $http_upgrade $connection_upgrade {
# default upgrade;
# '' close;
# }
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
#Gzip Compression
gzip on;
gzip_buffers 16 8k;
gzip_comp_level 6;
gzip_http_version 1.1;
gzip_min_length 256;
gzip_proxied any;
gzip_vary on;
gzip_types
text/xml application/xml application/atom+xml application/rss+xml application/xhtml+xml image/svg+xml
text/javascript application/javascript application/x-javascript
text/x-json application/json application/x-web-app-manifest+json
text/css text/plain text/x-component
font/opentype application/x-font-ttf application/vnd.ms-fontobject
image/x-icon;
gzip_disable "msie6";
#If you have a lot of static files to serve through Nginx then caching of the files' metadata (not the actual files' contents) can save
some latency.
open_file_cache max=1000 inactive=20s;
open_file_cache_valid 30s;
open_file_cache_min_uses 2;
open_file_cache_errors on;
access_log off;
include vhost/*.conf;
}
所有自定义的配置 都在vhost文件夹下面
3、现在贴出两个vhost文件夹下面的自定义配置
server {
listen 80;
server_name dev.hr.static.baidu.com;
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico|js|css|html|woff2|woff)$ {
root /deploy/www/baidu-www/web-hr;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
}
}
server {
listen 80;
server_name dev.am.static.baidu.com;
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico|js|css|html|woff2|woff)$ {
root /deploy/www/baidu-www/web-am;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
}
}
这个是监听80端口，注意server_name，这个服务名跟你访问的host要一致才可以实现，如果你要进入到hr的首页，那么你在浏览器的输入是dev.hr.static.baidu.com，这样才能正常访问到你指定的页面
server {
listen 80;
server_name am.dev.baidu.com;
access_log logs/am.baidu.com_nginx.log combined;
index index.html index.jsp index.php;
location ^~ /api {
proxy_pass http://127.0.0.1:8081/;#需要代理的地址
include proxy.conf;
}
location ^~ / {
root /deploy/www/baidu-www/web-am/;
}
}
这个是需要转发的后端服务，这个路径后面可以带项目名，同样也需要注意server——name
下面是反向proxy.conf的配置
表示使nginx阻止HTTP应答代码为400或者更高的应答 #proxy_intercept_errors on; proxy_redirect off; #以下三行，目的是将代理服务器收到的用户的信息传到真实服务器上 #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Ssl on; proxy_set_header Accept-Encoding ''; proxy_set_header Referer $http_referer; proxy_set_header Cookie $http_cookie; #允许客户端请求的最大单文件字节数 client_max_body_size 10m; #缓冲区代理缓冲用户端请求的最大字节数 client_body_buffer_size 128k; #nginx跟后端服务器连接超时时间(代理连接超时) proxy_connect_timeout 300; #连接成功后，后端服务器响应时间(代理接收超时) proxy_read_timeout 900; #设置代理服务器（nginx）保存用户头信息的缓冲区大小 proxy_buffer_size 32k; #proxy_buffers缓冲区，网页平均在32k以下的话，这样设置 proxy_buffers 4 64k; #高负荷下缓冲大小（proxy_buffers*2） proxy_busy_buffers_size 128k; #设定缓存文件夹大小，大于这个值，将从upstream服务器传 proxy_temp_file_write_size 64k; proxy_send_timeout 900; proxy_hide_header Vary;
最后附上Nginx的重启命令
进入到Nginx的安装目录下的sbin目录，执行./nginx -t 检查Nginx的配置文件是否正确；执行./nginx -s reload 重启服务
