在linux下使用top命令可以查看进程，但是单从文件名无法定位到进程的位置。

有如下两种方法：

（1）获取进程的pid，然后使用命令ls -l /proc/${pid}，这个命令可以列出该进程的启动位置。

ls -l /proc/11268

（2）/usr/sbin/lsof | grep ${进程名称} 这个命令也能列出进程的启动位置。

到/proc/4431下，ls -l 会看到（需要root权限）

/etc$ ls -l /proc/11268

1.1. 1.3 启动关闭nginx

全选复制放进笔记

## 检查配置文件是否正确# /usr/local/nginx-1.6/sbin/nginx -t # ./sbin/nginx -V     # 可以看到编译选项

## 启动、关闭# ./sbin/nginx        # 默认配置文件 conf/nginx.conf，-c 指定# ./sbin/nginx -s stop

或 pkill nginx

## 重启，不会改变启动时指定的配置文件# ./sbin/nginx -s reload

或 kill -HUP `cat /usr/local/nginx-1.6/logs/nginx.pid`

当然也可以将 nginx 作为系统服务管理，下载 nginx 到/etc/init.d/，修改里面的路径然后赋予可执行权限。

# service nginx {start|stop|status|restart|reload|configtest}

1.2. 找到nginx配置文件

网上说路径在这里，没有找到，使用搜索命令find找到。。

8.修改配置文件

cd /usr/local/nginx/conf

vi nginx.conf

/usr/local$ cd /

/$  find . -name 'nginx.conf'

./etc/nginx/nginx.conf

find . -name 'fcgi.conf'

1.3. ./etc/nginx/nginx.conf

http {

include       mime.types;

default_type  application/octet-stream;

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

include /etc/nginx/conf.d/*.conf;

}

1.4. etc/nginx/conf.d/eform.conf;

server {

}

location = /robots.txt { allow all; access_log off; log_not_found off; }

location = /favicon.ico { allow all; access_log off; log_not_found off; }

error_page 401 /401.html;

error_page 403 /403.html;

error_page 404 /404.html;

error_page 500 502 503 504 /50x.html;

location ~ \.php$ {

root           /mnt/www/eform/public;

#sock开启

fastcgi_pass    unix:/var/run/php5-fpm.sock;

#TCP开启

#fastcgi_pass   127.0.0.1:9000;

fastcgi_index   index.php;

#写入上一步自己创建fast-cgi的配置文件路径

include         fcgi.conf;

include         fastcgi_params;

}

# deny access to .htaccess files, if Apache's document root

# concurs with nginx's one

location ~ /\.ht {

#deny  all;

}

}

/$  find . -name 'fcgi.conf'

./etc/nginx/fcgi.conf

find . -name “php.ini”

find . -name  “php-fpm.conf”

2. Nginx的php安装原理

针对Nginx的php安装和针对apache的php安装是有区别的，因为Nginx中的php是以fastcgi的方式结合nginx的，可以理解为nginx代理了php的fastcgi，而apache是把php作为自己的模块来调用

/etc/nginx$ netstat   -anp  |grep php

unix  3      [ ]         STREAM     CONNECTED     14493    1068/php-fpm: maste

unix  3      [ ]         STREAM     CONNECTED     14494    1068/php-fpm: maste

/$ find . -name 'php.ini'

./etc/php.ini

du -sh   /mnt/www/eform/public

/$ du -sh   /mnt/www/eform/public

3.4G/mnt/www/eform/public

/$ du -sh   /mnt/www/
