CentOS7配置yum本地源时报错Repository ‘centos7-media‘: Error parsing config

本文解决了一个 CentOS 7 中 YUM 源配置错误的问题,该错误涉及到 gpgkey 的配置及注释的不当使用。通过移除配置文件中的注释,成功解决了错误。

错误如下:

已加载插件:fastestmirror
Repository 'centos7-media': Error parsing config: Error parsing "gpgkey = 'file://media/cdrom/RPM-GPG-KEY-CentOS-7    #GPG-KEY\xe6\x96\x87\xe4\xbb\xb6\xe8\xb7\xaf\xe5\xbe\x84'": URL must be http, ftp, file or https not ""

原因:是因为配置文件中有注释,把注释去掉就好了

[centos7-media]
name=Red Hat Centos linux 7.0
baseurl=file:///media/cdrom
enabled=1
gpgcheck=1
gpgkey=file:///media/cdrom/RPM-GPG-KEY-CentOS-7    #这里有注释会报错

估计是 centos在这个文件中不支持注释吧。或者是注释的位置不对。

[root@lsygitlab ~]# yum install gitlab-ce Loaded plugins: fastestmirror, langpacks Repository 'gitlab-ce': Error parsing config: Error parsing "baseurl = 'https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$ releasever/'": URL must be http, ftp, file or https not "" Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Run the command with the repository temporarily disabled yum --disablerepo=<repoid> ... 4. Disable the repository permanently, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> or subscription-manager repos --disable=<repoid> 5. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64 [root@lsygitlab ~]#

### 配置CentOS 7 YUM本地源遇到的Mount Error解决方案 当尝试在CentOS 7配置YUM本地源,如果出现`mount: special device CentOS-7-x86_64-DVD-1804.iso does not exist`错误,通常是因为ISO文件路径不正确或者未被识别为有效的设备。以下是可能的原因分析以及对应的解决方法: #### 可能原因及解决办法 1. **ISO 文件路径错误** 如果指定的ISO文件路径不存在,则会触发此错误。需要确认ISO文件的实际位置是否正确。 ```bash ls /path/to/CentOS-7-x86_64-DVD-1804.iso ``` 若上述命令无法找到该文件,则说明路径有误。应更正路径至实际存在的ISO文件。 2. **ISO 文件权限不足** 即使ISO文件存在,但如果当前用户无权访问它,也会引发类似的错误。可以通过以下方式验证并修复: ```bash chmod 644 /path/to/CentOS-7-x86_64-DVD-1804.iso ``` 3. **挂载目录不存在** 挂载目标目录必须事先创建。如果没有创建相应的挂载点,也需要手动建立: ```bash mkdir -p /mnt/cdrom ``` 4. **挂载命令语法问题** 正确的挂载命令应该如下所示: ```bash mount -o loop /path/to/CentOS-7-x86_64-DVD-1804.iso /mnt/cdrom/ ``` 上述命令中的`loop`选项用于将ISO镜像作为块设备加载[^1]。 5. **ISO 文件损坏或不完整** ISO文件本身可能存在损坏或下载过程中中断的情况。可以重新校验其MD5或SHA256哈希值来确保完整性。例如: ```bash sha256sum /path/to/CentOS-7-x86_64-DVD-1804.iso ``` 6. **SELinux 或 AppArmor 干扰** SELinux策略可能会阻止某些操作执行成功。临关闭SELinux测试效果如何: ```bash setenforce 0 ``` 如果问题得以解决,后续可调整具体的安全上下文设置而非完全禁用SELinux[^4]。 #### 示例脚本 下面提供一段完整的Shell脚本来完成以上步骤的操作: ```bash #!/bin/bash ISO_PATH="/path/to/CentOS-7-x86_64-DVD-1804.iso" MOUNT_POINT="/mnt/cdrom" if [[ ! -f "$ISO_PATH" ]]; then echo "Error: $ISO_PATH does not exist." exit 1 fi chmod 644 "$ISO_PATH" mkdir -p "$MOUNT_POINT" umount "$MOUNT_POINT" &>/dev/null || true mount -o loop "$ISO_PATH" "$MOUNT_POINT" echo "Mounted successfully at $MOUNT_POINT" ``` --- ###
