本篇內容主要講解“nginx proxy_pass反向代理配置實例分析”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“nginx proxy_pass反向代理配置實例分析”吧!
下面舉個小實例說明下：
centos7系統庫中默認是沒有nginx的rpm包的，所以我們自己需要先更新下rpm依賴庫
1）使用yum安裝nginx需要包括nginx的庫，安裝nginx的庫
[root@localhost ~]# rpm -uvh http://nginx.org/packages/centos/7/noarch/rpms/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2）使用下面命令安裝nginx
[root@localhost ~]# yum install nginx
3）nginx配置
[root@localhost ~]# cd /etc/nginx/conf.d/
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
}
[root@localhost conf.d]# cat /var/www/html/index.html
this is page of test!!!!4）啟動nginx
[root@localhost ~]# service nginx start //或者使用 systemctl start nginx.service
5）測試訪問（103.110.186.23是192.168.1.23機器的外網ip）
[root@localhost conf.d]# curl http://192.168.1.23 this is page of test!!!!
看看下面幾種情況：分別用http://192.168.1.23/proxy/index.html進行訪問測試
為了方便測試，先在另一臺機器192.168.1.5上部署一個8090端口的nginx，配置如下：
[root@bastion-idc ~]# cat /usr/local/nginx/conf/vhosts/haha.conf
server {
listen 8090;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
}
[root@bastion-idc ~]# cat /var/www/html/index.html
this is 192.168.1.5
[root@bastion-idc ~]# /usr/local/nginx/sbin/nginx -s reload測試訪問（103.110.186.5是192.168.1.5的外網ip）：
[root@bastion-idc ~]# curl http://192.168.1.5:8090 this is 192.168.1.5
192.168.1.23作為nginx反向代理機器，nginx配置如下：
1）第一種情況：
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy/ {
proxy_pass http://192.168.1.5:8090/;
}
}這樣，訪問http://192.168.1.23/proxy/就會被代理到http://192.168.1.5:8090/。p匹配的proxy目錄不需要存在根目錄/var/www/html里面
注意，終端里如果訪問http://192.168.1.23/proxy（即后面不帶"/"），則會訪問失敗！因為proxy_pass配置的url后面加了"/"
[root@localhost conf.d]# curl http://192.168.1.23/proxy/ this is 192.168.1.5 [root@localhost conf.d]# curl http://192.168.1.23/proxy <html> <head><title>301 moved permanently</title></head> <body bgcolor="white"> <center><h1>301 moved permanently</h1></center> <hr><center>nginx/1.10.3</center> </body> </html>
頁面訪問http://103.110.186.23/proxy的時候，會自動加上"/”（同理是由于proxy_pass配置的url后面加了"/"），并反代到http://103.110.186.5:8090的結果
2）第二種情況，proxy_pass配置的url后面不加"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy/ {
proxy_pass http://192.168.1.5:8090;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service那么訪問http://192.168.1.23/proxy或http://192.168.1.23/proxy/，都會失敗！
這樣配置后，訪問http://192.168.1.23/proxy/就會被反向代理到http://192.168.1.5:8090/proxy/
3）第三種情況
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy/ {
proxy_pass http://192.168.1.5:8090/haha/;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service
[root@localhost conf.d]# curl http://192.168.1.23/proxy/
192.168.1.5 haha-index.html這樣配置的話，訪問http://103.110.186.23/proxy代理到http://192.168.1.5:8090/haha/
4）第四種情況：相對于第三種配置的url不加"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy/ {
proxy_pass http://192.168.1.5:8090/haha;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service
[root@localhost conf.d]# curl http://192.168.1.23/proxy/index.html
192.168.1.5 hahaindex.html上面配置后，訪問http://192.168.1.23/proxy/index.html就會被代理到http://192.168.1.5:8090/hahaindex.html
同理，訪問http://192.168.1.23/proxy/test.html就會被代理到http://192.168.1.5:8090/hahatest.html
[root@localhost conf.d]# curl http://192.168.1.23/proxy/index.html 192.168.1.5 hahaindex.html
注意，這種情況下，不能直接訪問http://192.168.1.23/proxy/，后面就算是默認的index.html文件也要跟上，否則訪問失敗！
-------------------------------------------------------------------------------------
上面四種方式都是匹配的path路徑后面加"/"，下面說下path路徑后面不帶"/"的情況：
1）第一種情況，proxy_pass后面url帶"/"：
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy {
proxy_pass http://192.168.1.5:8090/;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service
2）第二種情況，proxy_pass后面url不帶"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy {
proxy_pass http://192.168.1.5:8090;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service
[root@localhost conf.d]#這樣配置的話，訪問http://103.110.186.23/proxy會自動加上"/”（即變成http://103.110.186.23/proxy/），代理到192.168.1.5:8090/proxy/
3）第三種情況
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy {
proxy_pass http://192.168.1.5:8090/haha/;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service這樣配置的話，訪問http://103.110.186.23/proxy會自動加上"/”（即變成http://103.110.186.23/proxy/），代理到http://192.168.1.5:8090/haha/
4）第四種情況：相對于第三種配置的url不加"/"
[root@localhost conf.d]# cat test.conf
server {
listen 80;
server_name localhost;
location / {
root /var/www/html;
index index.html;
}
location /proxy {
proxy_pass http://192.168.1.5:8090/haha;
}
}
[root@localhost conf.d]# service nginx restart
redirecting to /bin/systemctl restart nginx.service
這樣配置的話，訪問http://103.110.186.23/proxy，和第三種結果一樣，同樣被代理到http://192.168.1.5:8090/haha/
