2. 下载etrace
[root@slave1 ~]# pwd
/root [root@slave1 ~]git clone https://github.com/elcritch/etrace.git
3. 将etrace代码加入Ngnix
将ptrace.c拷贝至Nginx源码core目录下.

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf （指定配置文件启动）
6.
vi /usr/local/nginx/conf/nginx.conf 加入 daemon off;
master_process off;
7.开3个窗口
窗口1 cd /sbin
touch TRACE etrace nginx 或者 etrace nginx >log
窗口2 cd /sbin ./nginx
窗口三curl 127.0.0.1

spawn_fastcgi的安装、部署与配置wget https://github.com/lighttpd/spawn-fcgi/archive/v1.6.3.tar.gz[root@monitor spawn-fcgi-1.6.3]# pwd/root/spawn-fcgi-1.6.3[root@monitor spawn-fcgi-1.6.3]# ./autogen.sh[root@monitor spawn-fcgi-1.6.3]# ./configure[root@monitor spawn-fcgi-1.6.3]# make
编译好以后，将可执行文件移动到nginx的sbin目录下
cp ./src/spawn-fcgi /usr/local/nginx/sbin/ //（cp到nginx的安装目录下）

解决办法：
在/include/fcgio.h文件中加上 #include <stdio.h>，然后再编译安装就通过了。CGI程序:[root@monitor ~]# vi demo.cc #include <fcgi_stdio.h>#include <stdlib.h>#include <sys/types.h>#include <unistd.h>int main() {int count = 0;while (FCGI_Accept() >= 0) {printf("Content-type: text/html\r\n""\r\n""""FastCGI Hello!""Request number %d running on host%s ""Process ID: %d\n", ++count, getenv("SERVER_NAME"), getpid());}return 0;}[root@monitor ~]# ./demo./demo: error while loading shared libraries: libfcgi.so.0: cannot open shared object file: No such file or directory解决： 1.cp /usr/local/lib/libfcgi.so.0 /usr/lib 在/etc/ld.so.conf中加入 include /usr/lib 2./sbin/ldconfig -v[root@monitor ~]# ldd demo linux-vdso.so.1 => (0x00007fff0a4f1000) libfcgi.so.0 => /usr/lib/libfcgi.so.0 (0x00007f560e1cf000) libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f560dec9000) libm.so.6 => /lib64/libm.so.6 (0x0000003c4fc00000) libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f560dcb2000) libc.so.6 => /lib64/libc.so.6 (0x0000003c4ec00000) libnsl.so.1 => /lib64/libnsl.so.1 (0x0000003c51400000) /lib64/ld-linux-x86-64.so.2 (0x0000003c4e400000)mkdir -p /usr/local/nginx/cgibin/cp /root/deme /usr/local/nginx/cgibin/demo指定spawn-fcgi与 demo 这个CGI关联[root@monitor cgibin]# /usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 8088 spawn-fcgi: no FastCGI application given[root@monitor cgibin]# /usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 8088 -f /usr/local/nginx/cgibin/demo spawn-fcgi: child spawned successfully: PID: 23692参数含义如下：-f <fcgiapp> 指定调用FastCGI的进程的执行程序位置，根据系统上所装的情况具体设置。-a <addr> 绑定到地址addr。-p <port> 绑定到端口port。-s <path> 绑定到unix socket的路径path。-C <childs> 指定产生的FastCGI的进程数，默认为5。（仅用于PHP）-P <path> 指定产生的进程的PID文件路径。-u和-g FastCGI使用什么身份（-u 用户 -g 用户组）运行，CentOS下可以使用apache用户，其他的根据情况配置，如nobody、www-data等。浏览器上：http://120.24.160.93/demo.cgi (.cgi不能省)FastCGI Hello!Request number 4 running on host Process ID: 23692服务器上：[root@monitor cgibin]# ps -ef|grep demoroot 23692 1 0 15:46 ? 00:00:00 /usr/local/nginx/cgibin/demodemo 这个CGI一致在运行还可以监听其他端口:[root@monitor cgibin]# /usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9000 -f /usr/local/nginx/cgibin/demospawn-fcgi: child spawned successfully: PID: 23700[root@monitor cgibin]# /usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9001 -f /usr/local/nginx/cgibin/demospawn-fcgi: child spawned successfully: PID: 23702[root@monitor cgibin]# /usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9002 -f /usr/local/nginx/cgibin/demospawn-fcgi: child spawned successfully: PID: 23704[root@monitor cgibin]# /usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9003 -f /usr/local/nginx/cgibin/demospawn-fcgi: child spawned successfully: PID: 23706ctive Internet connections (servers and established)Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 127.0.0.1:9003 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:8088 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:9001 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:9002 0.0.0.0:* LISTEN [root@monitor cgibin]# ps -ef|grep demoroot 23692 1 0 15:46 ? 00:00:00 /usr/local/nginx/cgibin/demoroot 23700 1 0 15:57 ? 00:00:00 /usr/local/nginx/cgibin/demoroot 23702 1 0 15:58 ? 00:00:00 /usr/local/nginx/cgibin/demoroot 23704 1 0 15:58 ? 00:00:00 /usr/local/nginx/cgibin/demoroot 23706 1 0 15:59 ? 00:00:00 /usr/local/nginx/cgibin/demo
重启nginx或者重新加载配置文件
重新加载配置文件
1.kill -HUP [pid]
2.重启nginx
service nginx restart
3.killall nginx ./nginx
kill -HUP 是让进程挂起，睡眠;
kill -9 六亲不认的杀掉
kill -15 正常的退出进程
killall命令用于杀死指定名字的进程（kill processes by name）
1. yum install php PHP-CGI是PHP自带的FastCGI管理器 php-cgi -b 127.0.0.1:9000 php-cgi变更php.ini配置后需重启php-cgi才能让新的php-ini生效，不可以平滑重启 直接杀死php-cgi进程,php就不能运行了。(PHP-FPM和Spawn-FCGI就没有这个问题,守护进程会平滑从新生成新的子进程。）
2.Spawn-FCGI，PHP-FPM 都是fastcgi管理器 yum install php-fpm PHP-FPM是一个PHP FastCGI管理器 专门服务PHP Spawn-FCGI是一个通用的FastCGI管理服务器 通用的 PHP-FPM、Spawn-FCGI都是守护php-cgi的进程管理器 php-fpm,Spawn-FCGI的管理对象是php-cgi fastcgi是协议 php-cgi只是解释PHP脚本的程序 [root@monitor ~]# /usr/sbin/php-fpm [09-Jun-2016 17:59:33] NOTICE: fpm is running, pid 23943 [09-Jun-2016 17:59:33] NOTICE: ready to handle connections[root@monitor ~]# ps -ef|grep php-fpmroot 23943 23848 0 17:59 pts/0 00:00:00 php-fpm: master process (/etc/php-fpm.conf)apache 23944 23943 0 17:59 pts/0 00:00:00 php-fpm: pool wwwapache 23945 23943 0 17:59 pts/0 00:00:00 php-fpm: pool wwwapache 23946 23943 0 17:59 pts/0 00:00:00 php-fpm: pool wwwapache 23947 23943 0 17:59 pts/0 00:00:00 php-fpm: pool wwwapache 23948 23943 0 17:59 pts/0 00:00:00 php-fpm: pool wwwroot 23964 23900 0 18:01 pts/1 00:00:00 grep php-fpm
