查看当前运行程序的路径，如查看当前运行的nginx

命令：  ll /proc/运行程序的进程号/exe


1 查nginx进程号

[root@hadoop 7101]# ps -ef|grep nginx
root      7101     1  0 17:47 ?        00:00:00 nginx: master process /my/servers/nginx/sbin/nginx -c /my/servers/nginx/conf/nginx.conf
admin     7102  7101  0 17:47 ?        00:00:00 nginx: worker process                                                   
admin     7103  7101  0 17:47 ?        00:00:00 nginx: worker process                                                   
admin     7104  7101  0 17:47 ?        00:00:00 nginx: worker process                                                   
admin     7105  7101  0 17:47 ?        00:00:00 nginx: worker process

admin     7108  7101  0 17:47 ?        00:00:00 nginx: worker process                                                   
admin     7109  7101  0 17:47 ?        00:00:00 nginx: worker process                                                   
root      7129 28291  0 17:53 pts/0    00:00:00 grep nginx

进程号：7101

2 进入目录
[root@hadoop sbin]# cd /proc/7101
[root@hadoop 7101]# ls
attr       clear_refs       cpuset   fd      loginuid   mounts      numa_maps      pagemap      schedstat  stat     task

[root@hadoop 7101]# ll exe
lrwxrwxrwx. 1 root root 0 Aug 13 17:53 exe -> /my/servers/nginx/sbin/nginx

3 测试，可以看到运行的配置文件
[root@hadoop 7101]# /my/servers/nginx/sbin/nginx -t
nginx: the configuration file /my/servers/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /my/servers/nginx/conf/nginx.conf test is successful

4 查看版本
[root@hadoop 7101]# /my/servers/nginx/sbin/nginx -V
