Linux配置本地yum源
1、将oracle-linux-ol7.repo
配置文件备份
cp /etc/yum.repos.d/oracle-linux-ol7.repo /etc/yum.repos.d/oracle-linux-ol7.repo.bak
#删除原文件:
rm -rf /etc/yum.repos.d/oracle-linux-ol7.repo
2、编辑配置文件仅添加以下内容:
vi /etc/yum.repos.d/oracle-linux-ol7.repo
[ol7_latest]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=file:///mnt/cdrom
gpgcheck=0 #0表示关闭gpgkey检查,1是开启
enabled=1 #0表示关闭本地yum源,1是开启
3、创建挂载点:
mkdir /mnt/cdrom
4、挂载光盘镜像:
#服务器或虚拟机已经连接光盘镜像
mount /dev/sr0 /mnt/cdrom
#如果服务器或虚拟机没有连接光盘镜像,将镜像上传到机器,手动指定本地路径挂载镜像
#/u01/software/OracleLinux-R7-U8-Server-x86_64-dvd.iso为我的镜像所在目录
mount -o loop -t iso9660 /u01/software/OracleLinux-R7-U8-Server-x86_64-dvd.iso /mnt/cdrom
5、清除YUM缓存
# yum clean all
Loaded plugins: ulninfo
Cleaning repos: ol7_latest
#
6、列出所有可安装的安装包
报错:
# yum list
Loaded plugins: ulninfo
https://yum.oracle.com/repo/OracleLinux/OL7/UEKR5/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: yum.oracle.com; Unknown error"
Trying other mirror.
One of the configured repositories failed (Latest Unbreakable Enterprise Kernel Release 5 for Oracle Linux 7Server (x86_64)),
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=ol7_UEKR5 ...
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 ol7_UEKR5
or
subscription-manager repos --disable=ol7_UEKR5
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=ol7_UEKR5.skip_if_unavailable=true
failure: repodata/repomd.xml from ol7_UEKR5: [Errno 256] No more mirrors to try.
https://yum.oracle.com/repo/OracleLinux/OL7/UEKR5/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: yum.oracle.com; Unknown error"
#
报错说是因为ol7_UEKR
没有配置的问题
#查看/etc/yum.repos.d目录下
# ll /etc/yum.repos.d

-rw-r--r--. 1 root root 226 Apr 2 2020 virt-ol7.repo
该Oracle Linux版本在/etc/yum.repos.d
目录下有一个uek-ol7.repo
文件,这个文件并没有配置,也用不到,就改名做了一个备份
mv uek-ol7.repo uek-ol7.repo.bak
再次执行yum list
# yum list
...

zlib-devel.i686 1.2.7-18.el7 ol7_latest
zlib-devel.x86_64 1.2.7-18.el7 ol7_latest
zsh.x86_64 5.0.2-34.el7 ol7_latest
zziplib.i686 0.13.62-12.el7 ol7_latest
zziplib.x86_64 0.13.62-12.el7 ol7_latest

将需要的安装包使用yum install -y 包名
安装即可,卸载使用yum remove -y 包名
