无法将 ISCSI 磁盘挂载点更改为其他目录

5

问题：我无法将 ISCSI 磁盘挂载点更改为其他目录。

目前我已将 ISCSI 磁盘安装到 /iscsi2

我想将其更改为 /iscsi

我在 /etc/fstab 中将 /iscsi2 更改为 /iscsi，但挂载到 /iscsi 失败。

复现步骤：

根据 /etc/fstab 挂载 /iscsi2。失败，因为挂载点已重命名为 /iscsi
```
mount /iscsi2
mount: can't find /iscsi2 in /etc/fstab
```
根据设备路径挂载/iscsi2，成功。
```
mount /dev/sdd1 /iscsi2
```

表明已经安装：

lsblk -af | grep -i iscsi
L¦sdd1 ext4   ISCSI_Backup2    3829ed05-f445-425d-8213-3b1c2d41fba /iscsi2

卸载 /iscsi2：
```
umount /iscsi2
```

显示它已被卸载：

lsblk -af | grep -i iscsi
L¦sdd1 ext4   ISCSI_Backup2    3829ed05-f445-425d-8213-3b1c2d41fba

根据设备路径挂载 /iscsi。失败。
```
mount /dev/sdd1 /iscsi
```

显示它仍处于未安装状态：

lsblk -af | grep -i iscsi
L¦sdd1 ext4   ISCSI_Backup2    3829ed05-f445-425d-8213-3b1c2d41fba

知道为什么挂载到 /iscsi2 成功而挂载到 /iscsi 却失败吗？

Moodle 3.7 & Apache & 反向代理结果 ERR_TOO_MANY_REDIRECTS

0

具有反向代理结果 ERR_TOO_MANY_REDIRECTS 的 Moodle 3.7 Apache。

我有一个带有以下 vhosts 文件的 SSL 站点：

<VirtualHost *:80>
    RewriteCond %{HTTPS} off
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</VirtualHost>     


<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName moodle.site.com:443

SSLEngine on
SecAuditEngine On
RewriteEngine On

    ProxyPreserveHost On
    ProxyPass / http://101.102.103.104:80/
    ProxyPassReverse / http://101.102.103.104:80/

</VirtualHost>                                  
</IfModule>

我还将所有 80 个端口请求重定向到 SSL 端口。

命令

curl -I https://moodle.site.com/

结果：

HTTP/1.1 303 See Other

Strict-Transport-Security: max-age=15768000; includeSubDomains
Location: https://moodle.site.com

在 Moodle config.php 我有：

$CFG->wwwroot   = 'https://moodle.site.com';
$CFG->reverseproxy = true;
$CFG->sslproxy  = 1;

知道为什么当我尝试打开https://moodle.site.com URL 时在 Google Chrome 中出现“ERR_TOO_MANY_REDIRECTS”错误吗？

为什么 sed 命令可以交互工作，但不能在我的脚本中工作？[复制]

4

SED 命令不能在 Debian 下的 bash 中替换，但可以在命令行中使用。

在命令行中工作：

sed -i 's|/dev/disk/by-label/SR6D4|/dev/disk/by-label/SR4D4|g' /etc/my/config.xml

不在 bash 脚本中工作，不替换字符串：

from="SR6D4"
to="SR4D4"
path_from="/dev/disk/by-label/${from}"
path_to="/dev/disk/by-label/${to}"
echo "sed -i 's|${path_from}|${path_to}|g' $file"
sed -i 's|${path_from}|${path_to}|g' $file

为什么在bash中使用sed时不替换文件中的字符串？
