GPS日志插件更新

billy — Fri, 27 Aug 2010 15:11:40 +0000

终于在两年后把gps的这个插件加上了照片导入功能。现在显示的gps轨迹已经带了照片的经纬度并显示照片。通过php读取exif信息读出经纬度然后存入数据库。

同时还需要做的就是将这个照片导入和wordpress的相册插件结合起来，另外增加一些别的功能如相册浏览，exif信息等。

下一步需要增加海拔和速度的图表，更加直观。

nginx apache xcache 效果对比测试

安装后我进行了测试以下为测试结果
分别开启关闭xcache 运行两次ab -n 1000 http://bbs.k12zy.com/forum-19-1.html

Server Software: nginx/0.6.33
Server Hostname: bbs.k12zy.com
Server Port: 80
Document Path: /forum-19-1.html
Document Length: 32118 bytes

Time taken for tests: 38.976547 seconds
Requests per second: 25.66 [#/sec] (mean)
Time per request: 38.977 [ms] (mean)
Time per request: 38.977 [ms] (mean, across all concurrent requests)
Transfer rate: 814.16 [Kbytes/sec] received

Time taken for tests: 17.326479 seconds

Time per request: 17.326 [ms] (mean)
Time per request: 17.326 [ms] (mean, across all concurrent requests)
Transfer rate: 1831.47 [Kbytes/sec] received

那么apache服务器的效果如何呢，又做了测试

Server Software: Apache/2.2.3
Server Hostname: 121.250.15.4
Server Port: 80
Document Path: /forum-19-1.html
Document Length: 32116 bytes

Time taken for tests: 32.138246 seconds
Requests per second: 31.12 [#/sec] (mean)
Time per request: 32.138 [ms] (mean)
Time per request: 32.138 [ms] (mean, across all concurrent requests)
Transfer rate: 988.04 [Kbytes/sec] received

Time taken for tests: 20.6633 seconds
Requests per second: 49.98 [#/sec] (mean)
Time per request: 20.007 [ms] (mean)
Time per request: 20.007 [ms] (mean, across all concurrent requests)
Transfer rate: 1587.17 [Kbytes/sec] received

其中红色为开启xcache的值

结果来看开启xcache肯定要快，至于apache和nginx的fastcgi来比较缺让人看的不清楚，只能解释由于第一次测试的是nginx不开xcache可能在数据库端使其变慢，都以一次测试的值也不能算作科学统计，仅做为自己的测试吧。

安装 xcache 加速php

billy — Sat, 22 Nov 2008 15:44:33 +0000

在服务器中安装了xcache，来加速php的运行。

关于xcache 可以查看 http://www.ibm.com/developerworks/cn/opensource/os-php-fastapps1/

yum install php-devel

wget http://xcache.lighttpd.net/pub/Releases/1.2.2/xcache-1.2.2.tar.gz
tar -xvf xcache-1.2.2.tar.gz
cd xcache-1.2.2
phpize

./configure –enable-xcache –enable-xcache-coverager
make
make install

得到结果：
Installing shared extensions: /usr/lib/php/modules/
将配置加入php.ini
cat xcache.ini >> /etc/php.ini

编辑php.ini 将 xcache.so的路径改为 /usr/lib/php/modules/xcache.so
重启fastcgi spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u nobody -g nobody -f /usr/bin/php-cgi
安装 XCache Administration
修改php.ini xcache.admin.pass=”” 为md5(“密码”)的值

复制 admin 文件夹到web目录

浏览器中浏览

启用后居然不管用原来默认配置中xcache.size和xcache.var_size都是0M 改成合适的数值就好

nginx 的配置

billy — Sat, 22 Nov 2008 14:01:30 +0000

加入了php的支持，nginx使用的是fastcgi。

我使用的是centos5.2系统，其中已经通过yum安装了php，因为不想再自己重新编译了就采用spawn-fcgi的方式来做fastcgi，spawn-fcgi包含在lighttpd，

wget lighttpd

./configure;

make;

cp src/spawn-fcgi /usr/bin/spawn-fcgi

spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -u nobody -g nobody -f /usr/bin/php-cgi

加入开机启动

nginx 配置

加入了rewrite来做永久链接

server {
listen 222.132.76.204:80;
server_name www.wangjian.info;
access_log /export/hd1/weblog/gpsview.access.log main;

location / {
root /export/hd1/web/blog/;
index index.php;

if (-f $request_filename/index.html){
   rewrite (.*) $1/index.html break;
}
if (-f $request_filename/index.php){
   rewrite (.*) $1/index.php;
}
if (!-f $request_filename){
   rewrite (.*) /index.php;
}
location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /export/hd1/web/blog$fastcgi_script_name;
include fastcgi_params;
}
}
}

OK了，经过感觉，速度好像是快了点。继续测试中。
