1、优雅停止
信号：WINCH

[root@localhost~]# /appl/apache/bin/apachectl  -kgraceful-stop  #
[root@localhost ~]# elinks -dump http://192.168.137.3 #使用elinks访问测试
ELinks: 拒绝连接

2、优雅重启

信号：USR1
[root@localhost ~]# /appl/apache/bin/apachectl -k graceful
httpd not running, trying to start
[root@localhost ~]# ps aux |grep httpd

root      5683  0.0  0.0 103248   836 pts/1    S+   16:34   0:00 grep httpd
测试：
[root@localhost ~]# elinks -dump http://192.168.137.3 It works!

3、Apache正常启动、关闭、重启

[root@localhost ~]# /appl/apache/bin/apachectl -k stop
httpd (no pid file) not running
[root@localhost ~]# elinks -dump http://192.168.137.3 ELinks: 拒绝连接
[root@localhost ~]#
[root@localhost ~]# /appl/apache/bin/apachectl -k start
[root@localhost ~]# elinks -dump http://192.168.137.3 It works!
[root@localhost ~]# /appl/apache/bin/apachectl -k restart
[root@localhost ~]# elinks -dump http://192.168.137.3 It works!
