Apache 配置问题

Question

最近在 Ubuntu 上安装了 Apache2。

我在访问显示 Apache2 已成功安装的页面时遇到了一些问题。

运行

ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

什么都不返回。

运行“服务 apache2 状态”

apache2 is running

如果我在终端中运行命令“apache2”会给我一个错误列表:

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
(13)Permission denied: AH00072: make_sock: could not bind to address [::]:80
(13)Permission denied: AH00072: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
AH00015: Unable to open logs

然而，使用 'sudo apache2' 给了我这个:

AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf:
Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}

不确定这是否与我试图找到运行 apache 的本地服务器 IP 的问题有关。

任何帮助或指导表示赞赏!

运行 ifconfig 后编辑

一个接一个。

ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

这只会在连接确实通过 eth0 时显示。运行ifconfig查看您正在使用哪个界面。这还将向您显示您的机器具有的 IP 地址。

运行后遇到的错误apache2是多方面的。

对于 Could not reliably determine the server's ... you can fix that specific one here

接下来的三行提示套接字是因为 apache2 已经在运行并且无法绑定(bind)到端口，因为其他一些进程(正在运行的 apache 实例)已经绑定(bind)到它们。

该 block 中关于日志的最后一行是因为您以非特权用户身份运行 apache2 并且您的日志文件受到保护。

当您使用 sudo 运行 apache2 时，您会收到一大堆关于配置变量的错误，因为您尝试错误地启动 apache。
sudo service apache2 start|stop|restart将从 /etc/apache2/envvars 加载值在启动 apache 之前进入您的环境。这是您应该控制 apache 的方式。
