CentOS 5/6 改為可用的 yum 套件庫來源 (2022)
若執行 yum 出現:
http://mirror.centos.org/centos/6/os/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
To address this issue please refer to the below knowledge base article
表示系統預設的 yum 套件庫可能已經不存在!
我們可以在 vault.centos.org 找到可用的套件庫來源:
- vault.centos.org: http
- archive.kernel.org: http - rsync (rsync://archive.kernel.org::centos-vault/)
- linuxsoft.cern.ch: http - rsync (rsync://linuxsoft.cern.ch/centos-vault/)
- mirror.nsc.liu: http - rsync (rsync://mirror.nsc.liu.se::centos-store/)
CentOS 6.x
編輯 /etc/yum.repos.d/CentOS-Base.repo，將全部的內容改為 vault.centos.org 套件庫:
[base] name=CentOS-$releasever - Base #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ baseurl=https://vault.centos.org/6.10/os/$basearch/ gpgcheck=0 enabled=1 #released updates [updates] name=CentOS-$releasever - Updates #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ baseurl=https://vault.centos.org/6.10/updates/$basearch/ gpgcheck=0 enabled=1 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/ baseurl=https://vault.centos.org/6.10/extras/$basearch/ gpgcheck=0 enabled=1 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ baseurl=https://vault.centos.org/6.10/centosplus/$basearch/ gpgcheck=0 enabled=0 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib #baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/ baseurl=https://vault.centos.org/6.10/contrib/$basearch/ gpgcheck=0 enabled=0
查看套件庫:
$ yum clean all $ yum repolist Loaded plugins: fastestmirror, refresh-packagekit Loading mirror speeds from cached hostfile repo id repo name status base CentOS-6 - Base 6,713 extras CentOS-6 - Extras 47 updates CentOS-6 - Updates 1,193 repolist: 7,953
這樣就可以恢復使用了。
若之後 vault.centos.org 也無法使用，可以替換網址為其它剩下的套件庫。
CentOS 5.x
編輯 /etc/yum.repos.d/CentOS-Base.repo，將全部的內容改為 archive.kernel.org 套件庫:
[base] name=CentOS-$releasever - Base #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/ baseurl=http://archive.kernel.org/centos-vault/5.11/os/$basearch/ gpgcheck=0 enabled=1 #released updates [updates] name=CentOS-$releasever - Updates #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/ baseurl=http://archive.kernel.org/centos-vault/5.11/updates/$basearch/ gpgcheck=0 enabled=1 #packages used/produced in the build but not released [addons] name=CentOS-$releasever - Addons #baseurl=http://mirror.centos.org/centos/$releasever/addons/$basearch/ baseurl=http://archive.kernel.org/centos-vault/5.11/addons/$basearch/ gpgcheck=0 enabled=1 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/ baseurl=http://archive.kernel.org/centos-vault/5.11/extras/$basearch/ gpgcheck=0 enabled=1 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/ baseurl=http://archive.kernel.org/centos-vault/5.11/centosplus/$basearch/ gpgcheck=0 enabled=0 #contrib - packages by Centos Users [contrib] name=CentOS-$releasever - Contrib #baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/ baseurl=http://archive.kernel.org/centos-vault/5.11/contrib/$basearch/ gpgcheck=0 enabled=0
查看套件庫:
$ yum clean all $ yum repolist Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Excluding Packages in global exclude list Finished repo id repo name status addons CentOS-5 - Addons 0 base CentOS-5 - Base 2,781+10 extras CentOS-5 - Extras 272 updates CentOS-5 - Updates 660+150 repolist: 3,713
這樣就可以恢復使用了。
PS. 其實 CentOS 5.x 也可以如同 CentOS 6.x 將套件庫的來源設為「https://vault.centos.org/5.11」，但是執行 yum 會出現如下的 SSL 錯誤:
Traceback (most recent call last):
File "/usr/bin/yum", line 29, in ?
yummain.user_main(sys.argv[1:], exit_code=True)
...
return m2.ssl_connect(self.ssl, self._timeout)
M2Crypto.SSL.SSLError: unknown protocol
因此才改用「http://archive.kernel.org/centos-vault/5.11」
重建 rpm 資料庫
$ yum clean all $ rm -f /var/lib/rpm/__db* $ rpm --rebuilddb
錯誤處理
若 yum 出現下列訊息:
error was 14: problem making ssl connection
當試執行下列套件的更新:
$ yum update yum curl ca-certificates openssl nss
