我正在使用亚马逊Linux。我只是通过 yum 启动 Apache,但是,当我重新启动服务器时,我无法让它自动启动,尽管它是在命令行上启动的......
[myuser@mymachine ~]$ sudo service httpd start
[sudo] password for myuser:
Starting httpd: httpd: apr_sockaddr_info_get() failed for mymachine
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[ OK ]
[myuser@mymachine ~]$ telnet localhost 80
Trying 127.0.0.1...
Connected to localhost.

我已在下面设置了这些链接,并具有以下权限。配置文件是在安装时自动为我创建的...

然而,服务器重新启动后,一切都没有运行(我无法通过端口 80 连接 Telnet)。我还需要做什么才能使其在重新启动后启动?

[myuser@mymachine ~]$ ls -al /etc/rc3.d/*httpd*
lrwxrwxrwx 1 root root 15 Oct 18 22:03 /etc/rc3.d/K15httpd -> ../init.d/httpd
那是你的问题。 /etc/rc3.d 中以 K(代表kill)开头的脚本不会在引导时启动,而以 S 开头的脚本则会启动。
如果你这样做:
[myuser@mymachine ~]$ mv /etc/rc3.d/K15httpd /etc/rc3.d/S15httpd
你的问题将会得到解决。然而,这是手动要做的事情。最好的方法是使用 chkconfig 命令,如下所示:
[myuser@mymachine ~]$ chkconfig httpd on
