一、寫在前面
最近需要把阿里云上的四臺(tái)服務(wù)器的項(xiàng)目遷移到客戶提供的新的項(xiàng)目中，原來的四臺(tái)服務(wù)器中用到了一級(jí)域名和二級(jí)域名。比如aaa.abc.com 和bbb.abc.com 和ccc.abc.com。其中aaa.abc.com登錄，通過把cookie中的信息setDomain給.abc.com。其他系統(tǒng)可以共享這個(gè)cookie。但是新的四臺(tái)服務(wù)器中并沒有申請(qǐng)域名，只有四個(gè)ip:
192.168.0.1 單點(diǎn)登錄服務(wù)器
192.168.0.2
192.168.0.3
192.168.0.4
因?yàn)槊颗_(tái)服務(wù)器有兩個(gè)項(xiàng)目，都用到單點(diǎn)登錄，所以通過修改新的共享登錄方式花費(fèi)時(shí)間太多，于是在網(wǎng)上搜cookie的跨域登錄，嘗試了下，在192.168.0.1 單點(diǎn)登錄服務(wù)器中多次setDomain分別給2、3、4服務(wù)器，結(jié)果不理想，因?yàn)闉g覽器不允許。后來無意中看到nginx可以通過欺騙的方式共享cookie。于是想到原來公司部署nginx還有這層用法。
二、原來的nginx配置
先說下nginx的安裝，這個(gè)網(wǎng)上都有很多教程，不在贅述，我是參照于在Linux里安裝、啟動(dòng)nginx。需要注意的是./configure后面的各種with，我在配置啟動(dòng)過程遇到了一些問題:
|
1
|
nginx: [emerg] unknown directive "aio" in |
加上--with-file-aio
復(fù)制代碼 代碼如下:
Starting nginx: nginx: [emerg] the INET6 sockets are not supported on this platform in “[::]:80” of the
在后面加上--with-ipv6好使。
安裝完成后。主要是nginx.conf的配置
原來服務(wù)器的配置nginx.conf：

以上配置后，nginx啟動(dòng)后，通過訪問不同的域名來訪問不同服務(wù)器。而因?yàn)槎加卸?jí)域名.abc.com.cn。所以可以共享cookie。
nginx的文件結(jié)構(gòu)為：
三、修改后的nginx配置
主要是reverse-proxy.conf 不同

這樣就可以把192.168.0.1:9998 當(dāng)做單點(diǎn)服務(wù)器，登錄后的domain都為192.168.0.1 。其他的0.2、0.3都可以通過192.168.0.1nginx和單點(diǎn)服務(wù)器的不同端口訪問，那么就可以共享這個(gè)0.1的域名了。
四、最后
好吧，可能描述的不是那么清楚，有點(diǎn)亂。我所做的工作就是把原來的nginx配置中的端口和域名改成新服務(wù)器中的唯一一個(gè)ip把這個(gè)ip當(dāng)做那個(gè)域名，不同端口對(duì)應(yīng)不同二級(jí)域名。
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持服務(wù)器之家。
