通过系统的信号控制 Nginx
可以使用信号系统来控制主进程。默认,nginx 将其主进程的 pid 写入到 /usr/local/nginx/logs/nginx.pid 文件中。通过传递参数给 ./configure 或使用 pid 指令,来改变该文件的位置。
主进程可以处理以下的信号:
命令 | 说明 | 备注 |
---|---|---|
TERM, INT | 快速关闭 | |
QUIT | 从容关闭 | |
HUP | 重载配置 | 用新的配置开始新的工作进程 从容关闭旧的工作进程 |
USR1 | 重新打开日志文件 | |
USR2 | 平滑升级可执行程序 | |
WINCH | 从容关闭工作进程 |
下载http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz
./configure make cp ./src/spawn-fcgi /usr/local/nginx/sbin/
下载http://www.fastcgi.com/dist/fcgi.tar.gz
./configure make make install
#include <iostream> #include <fcgi_stdio.h>
using namespace std;
int main() {
/* Initialization Code */
int count = 0;
/* Start of response loop */
while (FCGI_Accept() >= 0)
{
//* body of response loop /*/
printf("Content-type: text/html/r/n" "/r/n" ""
"FastCGI Hello/! (C, fcgi_stdio library)" "Request number %d running on host %s " "Process ID: %d/n", /++count, getenv("SERVER_NAME"), getpid()); }
/* End of response loop */ return 0;
}
编译后为FastCGISameple
/usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 25 -u www -f /usr/local/nginx/fcgi/FactCGISample
vi /usr/local/nginx/conf/nginx.conf
location ~ /.cgi$
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.cgi;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
别忘了,重新加载配置文件
$sudo kill -HUP 26010
打开浏览器,输入http://localhost/1.cgi ,就显示
FastCGI Hello! (C, fcgi_stdio library)Request number 1 running on host localhost Process

下载:http://home.tiscali.cz:8080/~cz210552/distfiles/webbench-1.5.tar.gz
安装:
tar zxvf webbench-1.5.tar.gz cd webbench-1.5
make && make install
使用:
webbench -c 500 -t 30 http://127.0.0.1/test.jpg
500是并发连接数,30是时间单位是秒
用ab测试的结果,在我的虚拟机上,看起来性能很不错
(Apache Bench是Apache自带的工具包)
