今天在配置Apache的时候，为了查看记录方便，将所有的APACHE的日志目录下面的文件均删除了
[root@localhost logs]# pwd
/usr/local/*/service/apache/logs
[root@localhost logs]# ll
总用量 28
-rw-r--r-- 1 root root 385 3月 13 16:31 access_log
-rw-r--r-- 1 root root 1083 3月 13 16:31 error_log
-rw-r--r-- 1 root root 6 3月 13 16:31 httpd.pid

[root@localhost logs]#
然后重启的时候提示上面的错误，最后看文件的时候，竟然有一个httpd.pid文件，好吧。应该是这个pid文件被删除了，导致出现的这个问题了
那直接查一下当前ps进程中的ID号是什么
[root@localhost logs]# ps -ef|grep 'apache'
root 18369 1 0 16:31 ? 00:00:00 /usr/local/*/service/apache/bin/httpd
9004 18371 18369 0 16:31 ? 00:00:00 /usr/local/*/service/apache/bin/httpd
9004 18372 18369 0 16:31 ? 00:00:00 /usr/local/*/service/apache/bin/httpd
9004 18373 18369 0 16:31 ? 00:00:00 /usr/local/*/service/apache/bin/httpd

root 18639 12792 0 16:41 pts/0 00:00:00 grep apache
[root@localhost logs]#
然后再直接生成一个httpd.pid文件，内容为主进程ID号
echo "">httpd.pid
再重启一下apache服务，最终恢复正常
