安卓nginx负载均衡集群的搭建

来源：互联网发布：人工智能计算器编辑：程序博客网时间：2024/05/29 10:40

昨晚研究了一晚，现在用一个效率更高的方案：直接在安卓系统上运行而不chroot到linux镜像下。
安卓已经有人做好一个集成环境了：https://sourceforge.net/projects/anmpp/
论坛链接：http://webthen.net/forum-36-1.html ;
你需要下载一个apk和一个zip。apk用于控制，zip里面包含了 nginx mysql pgsql php 的二进制文件和配置文件。如果apk里面有一键安装，如果不行就打开anmpp.sh，自己看着办。
环境搭建完成之后，我们打开bftpd、nginx、php-fpm这三个，然后启动环境。
浏览器输入172.0.0.1，看到phpinfo了，说明成功运行。
bftpd用户名密码都是root，开bftpd是为了方便传文件。（早期的anmpp是没有这个的）
==============================================================
环境搭建好了，一切都好办！你能感受到linux的强大之处吗？安卓基于linux，安卓也可以做集群！
测试设备两台：U960s3、NX510J
U960s3的IP：2.88.1.4
NX510J的IP：2.88.1.5
参考昨天的研究，现在打开ftp://2.88.1.5，登录，进入ftp://2.88.1.5/data/data/android.nginx/conf/，下载nginx.conf这个文件进行修改。修改后上传，覆盖原来的那个。

=============================================================================
进入 ftp://2.88.1.5/data/data/android.wwwroot/ 和 ftp://2.88.1.4/data/data/android.wwwroot/
分别放入一个同名但内容不同的html文件，然后重启2.88.1.5的nginx，以读取最新的配置文件。
浏览器打开2.88.1.5，不断刷新，发现页面不断地换，负载均衡集群搭建成功！
这个只是一个雏形，nginx的负载均衡的配置还能更复杂一点，例如让一个用户保持访问同一台服务器，以保持数据一致。如果不这样做，放个雅黑PHP探针上去看看，会发现下面的资源监控是不断在两台服务器之间切换的。

看看探针的图，会不断地跳。

linux的强大，你感受到了吗？
