ng的用途就不用說了,反向代理么,都知道,不過以前一直不太理解怎沒配,現在終於理解點了
1.下載ng,如圖:

2.先解壓,解壓后的路徑不建議有空格和中文,其次配置環境變量,加到系統path

3.啟動ng win+R---->cmd---->start nginx
4.修改配置文件
#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;
sendfile on;
keepalive_timeout 65;
gzip on;
#tomcat集群,這里只有一台機器,不管什么均衡策略都用不到
upstream tomcat_cxts {
ip_hash; #均衡策略
server localhost:8081 max_fails=3 fail_timeout=3s;
}
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
#靜態圖片轉發配置
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
root D:/webapps/static_resource/imgs;
if (-f $request_filename) {
expires 1d;
break;
}
}
#根據項目名稱進行轉發,如果是cxts,轉發到上面定義的名字叫tomcat_cxts的upstream組
location /cxts {
proxy_redirect off;
proxy_set_header Upgrade $http_upgrade; #websocket配置參數
proxy_set_header Connection "upgrade"; #websocket配置參數
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_pass http://tomcat_cxts/cxts; #英文字義:代理傳遞,即拿到數據傳給哪個,這里的tomcat_cxts就是上面配置的upstream
proxy_read_timeout 2; #websocket不需要此參數,加上去websocket會自動斷開
}
access_log logs/cxts.log;
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
轉發策略還可以寫if條件,ng還有很多內置變量,監聽地址還支持正則表達式,結合起來我覺得想怎么轉都行了
5.監測配置是否能通過檢查 nginx -t
6.nginx -s reload 重新加載配置
