如何使用 yum 安裝作業系統包？
我需要安裝以下軟體包：
gcc: gcc-c++-4.4.7-3.el6.x86_64 Flex: flex-2.5.35-8.el6.x86_64 Bison: bison-2.4.1-5.el6.x86_64 Glib: glib2-devel-2.22.5-7.el6.x86_64 & glibc-devel-2.12-1.107.el6_4.2.x86_64 Pcre: pcre-7.8-6.el6.x86_64 & pcre-devel-7.8-6.el6.x86_64 logrotate: logrotate-3.7.8-16.el6.x86_64 sendmail: sendmail-8.14.4-8.el6.x86_64 & sendmail-cf-8.14.4-8.el6.noarch
yum從下面的儲存庫中使用。# yum repolist Loaded plugins: package_upload, product-id, search-disabled-repos, subscription-manager repo id repo name status !RBC_RBC-Tools-RHEL7_rbc-tools-rhel-7Server-x86_64-rpms rbc-tools-rhel-7Server-x86_64-rpms 9 !rhel-7-server-extras-rpms/x86_64 Red Hat Enterprise Linux 7 Server - Extras (RPMs) 747 !rhel-7-server-optional-rpms/7Server/x86_64 Red Hat Enterprise Linux 7 Server - Optional (RPMs) 13,201 !rhel-7-server-rpms/7Server/x86_64 Red Hat Enterprise Linux 7 Server (RPMs) 18,022 !rhel-7-server-satellite-tools-6.1-rpms/x86_64 Red Hat Satellite Tools 6.1 (for RHEL 7 Server) (RPMs) 86 !rhel-7-server-supplementary-rpms/7Server/x86_64 Red Hat Enterprise Linux 7 Server - Supplementary (RPMs) 270 repolist: 32,335但是，我得到以下錯誤：
# yum install gcc-c++-4.4.7-3.el6.x86_64 Loaded plugins: package_upload, product-id, search-disabled-repos, subscription-manager RBC_RBC-Tools-RHEL7_rbc-tools-rhel-7Server-x86_64-rpms | 1.8 kB 00:00:00 rhel-7-server-extras-rpms | 2.0 kB 00:00:00 rhel-7-server-optional-rpms | 2.0 kB 00:00:00 rhel-7-server-rpms | 2.0 kB 00:00:00 rhel-7-server-satellite-tools-6.1-rpms | 2.1 kB 00:00:00 rhel-7-server-supplementary-rpms | 2.3 kB 00:00:00 No package gcc-c++-4.4.7-3.el6.x86_64 available. Error: Nothing to do如何解決此錯誤？我需要添加更多儲存庫嗎？如果是，如何？
如果您正在尋找安裝 GCC，您需要做的就是
yum install gcc-c++如果您可以訪問它們，它將獲取它的依賴項，否則它將出錯。對於其餘的包，只需在 <name>-<version number> 之前輸入文本名稱。yum install flex bison sendmail只需查看其他軟體包是否作為依賴項安裝，如果沒有返回並使用yum install <name>.如果您需要更多幫助來理解
yum，只需鍵入man yum以獲取更多參考和詳細資訊yum。[root@server thebtm]# yum install gcc Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirror.its.sfu.ca * epel: muug.ca * extras: muug.ca * ius: mirrors.kernel.org * updates: mirror.its.sfu.ca Package gcc-4.8.5-28.el7_5.1.x86_64 already installed and latest version Nothing to do未安裝時的範例：
