一、快速入门 1. 背景

使用nginx做反向代理的时候，可以简单的直接把请求原封不动的转发给下一个服务。设置proxy_pass请求只会替换域名，如果要根据不同的url后缀来访问不同的服务，则需要通过如下方法：

2. 案例1 server { listen 8000; server_name abc.com; access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main; location ^~/user/ { 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-NginX-Proxy true; proxy_pass http://user/; } location ^~/order/ { 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-NginX-Proxy true; proxy_pass http://order/; } }

^~/user/表示匹配前缀是user的请求，proxy_pass的结尾有/，则会把/user/*后面的路径直接拼接到后面，即移除user。

3. 案例2 upstream user { server localhost:8089 weight=5; } upstream order { server localhost:8090 weight=5; } server { listen 80; server_name abc.com; access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main; location ^~/user/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; rewrite ^/user/(.*)$ /$1 break; proxy_pass http://user; } location ^~/order/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; rewrite ^/order/(.*)$ /$1 break; proxy_pass http://order; } }

proxy_pass结尾没有/， rewrite重写了url。

二、实战 2.1. 配置备份 cd /usr/local/nginx/conf/ cp nginx.conf nginx.conf.bak 2.2. 配置清空

清空nginx.conf文件内容

cat /dev/null > nginx.conf 2.3. 配置初始化

添加以下内容在这里插入图片描述

user ec2-user ec2-user; worker_processes 1; 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; tcp_nodelay on; keepalive_timeout 65; include /usr/local/nginx/conf/conf.d/*.conf; } 2.4. 配置统一管理

在conf目录下面创建conf.d文件夹，用于存储永不同环境的配置文件

mkdir conf.d 2.5. 开发配置

添加开发环境配置文件dev.conf

cd conf.d vim dev.conf

添加以下内容在这里插入图片描述

##############################################DEV环境################################################## server { listen 80; server_name dev-ams.gblfy.com.cn; location / { 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-NginX-Proxy true; proxy_pass http://xxx.xxx.xxx.xxx:8082; } location ^~/dev-api/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; rewrite ^/dev-api/(.*)$ /$1 break; proxy_pass http://xxx.xxx.xxx.xxx:8080; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } 2.6. UAT配置

添加 uat环境配置文件uat.conf

cd conf.d vim uat.conf

内容详细如下在这里插入图片描述

###############################################UAT环境################################################## upstream app-cluster-test { server xxx.xxx.xxx.xx1:8080; server xxx.xxx.xxx.xx2:8080; } server { listen 80; server_name uat-ams.gblfy.com.cn; location / { 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-NginX-Proxy true; proxy_pass http://xxx.xxx.xxx.xxx:8082; } location ^~/uat-api/ { proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; rewrite ^/uat-api/(.*)$ /$1 break; proxy_pass http://app-cluster-test; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } 2.7. 启动nginx /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
