项目描述:
项目描述: Docker基于LXC实现了把lamp+wordpress架构封装到一个完整的文件系统中,docker提供了所需的一切代码,运行环境等。由于docker使用独立于主机的文件系统,可以确保架构在不同的主机环境中仍然保持运行环境不变,这样为整个架构服务的迁移提供了极大的便捷性。WordPress是使用PHP语言开发的博客平台,支持PHP和MySQL数据库的服务器上架设。lamp是一个使用apache为web服务器,PHP负责解释动态请求,MySQL提供用户数据服务,正好完全兼容wordpress对PHP和MySQL的需求。
nginx提供缓存提升性能
lamp+wordpress架构:172.25.254.110
nginx反响代理服务器:172.25.254.11
在lamp架构上,做虚拟主机服务:00.wordpress.com和01.wordpress.com两个站点维护不同用户的wordpress博客,主页内容复杂度完全一致!
测试思路:使用nginx反响代理服务器对01.wordpress.com做缓存处理。00.wordpress.com不做任何处理。
nginx服务器(172.25.254.11)配置文件修改的核心文件:
proxy_cache_path /nginx/cache2 levels=1:2:1 keys_zone=coco:20m max_size=1g; location / { proxy_pass http://01.wordpress.com; proxy_cache coco; proxy_cache_valid 200 304 1d; proxy_buffering on; }
nginx服务器添加了域名解析:
[root@localhost nginx]# cat /etc/hosts | grep 172.25.254.110 172.25.254.110 wordpress wordpress.com 00.wordpress.com 01.wordpress.com
由于00.wordpress.com没有nginx缓存,此时进行进行压力测试:
测试1

加大压力:
[root@localhost nginx]# ab -n 300 -c 20 http://00.wordpress.com/wordpress/ This is ApacheBench, Version 2.3 <$Revision: 1430300 $> Copyright 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Licensed to The Apache Software Foundation, http://www.apache.org/ Benchmarking 00.wordpress.com (be patient) Completed 100 requests Completed 200 requests Completed 300 requests Finished 300 requests Server Software: Apache/2.4.6 Server Hostname: 00.wordpress.com Server Port: 80 Document Path: /wordpress/ Document Length: 53724 bytes Concurrency Level: 20 Time taken for tests: 127.063 seconds Complete requests: 300 Failed requests: 0 Write errors: 0 Total transferred: 16203900 bytes HTML transferred: 16117200 bytes Requests per second: 2.36 [#/sec] (mean) Time per request: 8470.856 [ms] (mean) Time per request: 423.543 [ms] (mean, across all concurrent requests) Transfer rate: 124.54 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 0 1.9 0 23 Processing: 523 8342 1326.9 8176 12541 Waiting: 300 7815 1257.2 7690 12020 Total: 523 8343 1327.1 8176 12541 Percentage of the requests served within a certain time (ms) 50% 8176 66% 8398 75% 8635 80% 8953 90% 10095 95% 10488 98% 11265 99% 12439 100% 12541 (longest request)
真实服务器的链接状态:
[root@wordpress conf.d]# netstat -at| awk '{print $6} '| sort | uniq -c 1 established) 23 ESTABLISHED 1 Foreign 6 LISTEN 136 TIME_WAIT [root@wordpress conf.d]# top -n 1 top - 03:04:32 up 9:04, 3 users, load average: 19.38, 7.83, 4.40 //可以看到,cpu负载特别的大
nginx服务器通过反响代理将访问172.25.254.11的请求发送给01.wordpress.com/wordpress。然后在nginx服务器的/nginx/cache2目录内进行缓存。

在nginx服务器上查看缓存:

不断进行添加压力:此时的链接为10000,并发为1000

Requests per second:每秒接收的请求数
Time per request:每个请求被处理用时
Transfer rate:响应速率
Total transferred:总共获取数据两
可以看到有无缓存,天差地别!!!也算是对lamp+wordpress的一个性能提升。
