我们的服务器有两个接口，一个用于通过互联网连接，另一个用于内部网络。

172.20.54.10 -> Interface with static ip for connecting through internet
10.1.1.1     -> Internal network

看到以下配置

$ ip route
default via 172.20.54.1 dev enp12s0f1 proto static metric 20100
10.1.1.0/24 dev enp12s0f0 proto kernel scope link src 10.1.1.1 metric 101
169.254.0.0/16 dev enp12s0f1 scope link metric 1000
172.20.54.0/24 dev enp12s0f1 proto kernel scope link src 172.20.54.10 metric 100
$ ip addr

       valid_lft forever preferred_lft forever
3: enp12s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

    inet6 fe80::b0cf:3f53:bb4e:d836/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

内部网络包含一些具有 10.1.1.X IP 地址的虚拟机，它们似乎没有通过服务器的公共接口连接到互联网。服务器是 Ubutnu 20.04。

我应该为ip转发配置其他东西吗？

更新：

在ip_forward内核中启用

$ sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

我还不得不说，虚拟机（例如 10.1.1.3）能够 ping 专用接口 10.1.1.1，但无法 ping 8.8.8.8。

在此处输入图像描述

我想在 Apache 上设置 SSL 配置。我在网上看到的只是应该有一些 .key 和 .crt 文件。但是，我有这些文件

# ls
fullchain.crt  private.pem
certificate.crt             order          public.pem

我根据这里的解释尝试了以下配置，但是，通过重新启动httpd ，我收到一个错误，提示找不到私钥。

SSLEngine on
SSLCertificateFile /home/snadmin/certificate.crt
SSLCertificateKeyFile /home/snadmin/public.pem
SSLCertificateChainFile /home/snadmin/fullchain.crt
<Directory "/var/www/html/">

我该如何改变呢？

我们的服务器配置了内部 IP。然后在防火墙中，管理员映射了一个有效的 IP 地址 (2.XYZ)。所以，ipconfig命令显示

eth1      Link encap:Ethernet  HWaddr 00:E0:61:36:D5:34
          inet addr:172.20.54.10  Bcast:172.20.54.255  Mask:255.255.255.0
          inet6 addr: fe80::270:81ef:fec6:d534/64 Scope:Link

但是，我们使用ssh 2.X.Y.Z. 现在，我想设置 apache web 服务器，以便在 web 浏览器中输入 2.XYZ。所以，我打开/etc/httpd/conf/httpd.conf并修改

Listen 2.X.Y.Z:80
Listen 80

我用数字替换了 XYZ。问题是，当我重新启动 httpd 时，出现此错误

Starting httpd: (99)Cannot assign requested address: make_sock: could not bind to address 2.X.Y.Z:80
no listening sockets available, shutting down
Unable to open logs
                                                       [FAILED]

更新 1：

如果我替换Listen 2.X.Y.Z为Listen 172.20.54.10，那么我会收到此错误

Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
                                                       [FAILED]

如果我评论该行，服务将启动。但是，在浏览器中，有效的 IP 2.XYZ 不起作用。相反，内部 IP172.20.54.10有效。换句话说，apache 测试页面仅从本地网络显示。

在 Centos-6 机器上，我设置了 Apache Web 服务器，默认文件夹是/var/www/html. 在存在空白的情况下index.html，通过在浏览器中输入机器的 IP 地址，我看到了空白的白色屏幕。这意味着，Web 服务器正在工作。

当我放一个文件供下载时，问题是当我输入机器的IP地址时，我仍然看到空白页。我希望看到像这样的树状结构。

我该如何解决？

每当我想重新启动dnsmasq服务时，我都会收到此错误

如错误消息中所述，这些命令中没有有用的信息。

所以，第 4 行是dhcp-range=192.168.1.1,192.168.1.20,static. 我在 ubuntu-12.04 中使用了相同的内容。

更新：

无论如何，正确的语法是dhcp-range=192.168.1.0,static. 我不知道 12.04 是如何工作的！

我想检查客户端是否可以通过 rtsp://192.168.1.5:554 访问服务器。如您所见，rtsp 协议和端口#554 必须打开并在服务器上工作。

我可以添加吗

iptables -A INPUT -m state --state NEW -p tcp --dport 554 -j ACCEPT

但协议被指定为 tcp。将其更改为-p rtsp也不起作用。

对此有任何想法吗？

在服务器节点上，可以访问导出的文件夹。但是，在重新启动（服务器和客户端）后，不再可以从客户端访问该文件夹。

在服务器上

# ls /data
Folder1
Forlder2

并且 /etc/exports 文件包含

/data 192.168.1.0/24(rw,no_subtree_check,async,no_root_squash)

在客户端

# ls /data
ls: cannot access /data: Stale NFS file handle

我不得不说客户端的共享文件夹没有问题，但是在重新启动（服务器和客户端）后，我看到了这条消息。

有什么办法可以解决吗？

对于网络接口，我为 DHCP 定义了一个地址范围。

什么会导致此类错误，我该如何解决？

我们的服务器必须有网络接口。第一个有一个我们运行 httpd 的有效 IP，第二个有一个内部 IP (192.168.XX)。下面列出的更多信息

# cat /etc/hosts
127.0.0.1      localhost.localdomain localhost
192.168.1.5    srv1



# cat /etc/httpd/conf/httpd.conf
...
<VirtualHost *:80>
   ServerAdmin [email protected]
   DocumentRoot /var/www/html/munin
   ServerName 124.205.99.114
   ErrorLog logs/dummy-host.example.com-error_log
   CustomLog logs/dummy-host.example.com-access_log common
      <Directory /var/www/html/munin>
        Satisfy any
      </Directory>
</VirtualHost>

当我重新启动 httpd 时，我看到一个警告是

# /etc/init.d/httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 192.168.1.5 for ServerName
                                                           [  OK  ]

你可能会说这只是一个警告，但是当我在网络浏览器中输入 IP 地址时，没有显示 index.html 文件，我得到了The connection has timed out

更新：

似乎警告与“超时”问题无关。的输出iptables -nvL如下

# iptables -nvL

 pkts bytes target     prot opt in     out     source               destination

更新 2：

我用这个命令允许端口 80

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

可以用这个输出来验证

# iptables -nvL
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

我重新启动了服务network，httpd但仍然无法在浏览器中打开 index.html。

在基于 Redhat 的 linux (amd64) 上制作我的程序时，出现此错误：

/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status

搜索互联网显示我没有安装 zlib 32 位版本。快速搜索显示我有那个包裹

[root@localhost trunk]# find / -name libz*
/lib64/libz.so.1
/lib64/libz.so.1.2.3
/lib/libz.so.1
/lib/libz.so.1.2.3
/usr/lib64/libz.so
/usr/lib64/purple-2/libzephyr.so
/usr/lib64/libzip.so.1.0.0
/usr/lib64/libzip.so.1

如您所见，两者都/lib包含/lib64libz 文件。接下来我尝试找到 ldd 搜索路径，它显示同时包含 32 位和 64 位文件夹

[root@localhost trunk]# ldconfig -v | grep -v ^$'\t'
/usr/lib64/ctapi:
/usr/lib64/mysql:
/usr/lib64/tcl8.5/tclx8.4:
/usr/lib64/xulrunner-2:
/lib:
/lib64:
/usr/lib:
/usr/lib64:
/lib/i686: (hwcap: 0x0008000000000000)
/lib64/tls: (hwcap: 0x8000000000000000)  
/usr/lib64/tls: (hwcap: 0x8000000000000000)
/usr/lib64/sse2: (hwcap: 0x0000000004000000)
/lib/i686/nosegneg: (hwcap: 0x0028000000000000)

所以我想知道为什么我仍然会收到该错误！！！！

更新

我安装了zlib-devel（i686 和 x86_64），这里是确认信息

 [root@localhost trunk]# yum list zlib-devel
 Installed Packages
 zlib-devel.i686     1.2.3-27.el6             @sl
 zlib-devel.x86_64   1.2.3-27.el6             @sl

但是我仍然遇到同样的错误。

更新 2

修复不正确的符号链接后，我现在有

[root@localhost trunk]# ls -l /lib/libz.so*
lrwxrwxrwx. 1 root root    18 Feb 23 22:58 /lib/libz.so -> /usr/lib64/libz.so
lrwxrwxrwx. 1 root root    13 Feb 18 12:06 /lib/libz.so.1 -> libz.so.1.2.3
-rwxr-xr-x. 1 root root 75332 Dec 10  2011 /lib/libz.so.1.2.3

但错误依然存在

我发现我必须安装静态库。不知道为什么Makefile要搜索静态库！包名请参考我的评论。

我怎样才能找到的搜索路径ldd？假设ldd回报

[mahmood@dhcppc2 bin]$ ldd /home/mahmood/amd64-linux/lib/scsi-bus.so
        linux-vdso.so.1 =>  (0x00007fffc27c7000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x00007ffb13a25000)
        libstdc++.so.5 => not found

        /lib64/ld-linux-x86-64.so.2 (0x00000037d6000000)

我想知道默认位置是ldd什么？我的意思是/lib64或/usr/lib或/usr/lib64......？

是否有可能找到正在运行的进程的命令行pid？的输出/proc/${PID}/cmdline似乎删除了空格字符，很难读取输出。

ldd是显示共享库文件位置的有用命令。假设，以下命令

$ ldd foo.so
      libpython2.4.so => /path/to/file

我怎样才能删除那个链接，这样我就会有

$ ldd foo.so
      libpython2.4.so => not found

？
