下面舉個小實例說明下:
centos7系統函式庫中預設是沒有nginx的rpm包的,所以我們自己需要先更新下rpm依賴函式庫
1)使用yum安裝nginx需要包含nginx的函式庫,安裝nginx的函式庫
[root@localhost ~]# rpm -uvh http://nginx.org/packages/centos/7/noarch/rpms/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2)使用下列指令安裝nginx
[root@localhost ~]# yum install nginx
3) nginx設定
[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)測試存取(103.110.186.23是192.168.1.23機器的外網)
[root@localhost conf.d]# curl http://192.168.1.23 this is page of test!!!!
看看以下幾種情況:分別用http://192.168.1.23/proxy/index.html來存取測試
為了方便測試,先在另一台機器192.168.1.5上部署一個8090埠的nginx,設定如下:
[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
測試存取(103.110.186.5是192.168.1.5的外網路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:
[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裡面
[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"/”(同理是由於proxy_pass配置的url後面加了"/"),並反代到http://103.110.186.5:8090的結果 2)第二種情況,proxy_pass配置的url後面不加"/"
[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那麼訪問http://192.168.1.23/proxy或http://192.168.1.23/proxy/,都會失敗!
[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這樣設定的話,訪問http://103.110.186.23/proxy代理到http://192.168.1.5:8090/ haha/ 4)第四種情況:相對於第三種配置的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上面配置後,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,不能直接存取http://192.168.1.23/proxy/,後面就算是預設的index.html檔案也要跟上,否則存取失敗!
上面四種方式都是符合的path路徑後面加上"/",下面說下path路徑後面不帶"/"的情況:
[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/; } } [root@localhost conf.d]# service nginx restart redirecting to /bin/systemctl restart nginx.service
[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]#這樣設定的話,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/),代理程式到http://192.168.1.5:8090/haha/ #4)第四種情況:相對於第三種配置的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/
