Chapter IV deploying yum warehouse services
1. notes
systemctl start command: reboot
systemctl enable command: boot from the start
netstat -anput | grep command: See if open
echo $:? determine whether the command is executed successfully, 0 on success, non-zero unsuccessful
yum provides package: Check the package name
2. Based on the FTP : // local CD-ROM to create the y- UM warehouse processes
-Y ftp the install yum (installed ftp package)
umount / dev / SR0 (uninstalled CD / dev / SR0 )
mkdir / var / FTP / centos7 (creates directories in / var / FTP / centos7 )
Mount / dev / sr0 / var / FTP / centos7 / (mount / dev / sr0 mount / var / FTP / centos7 )
/etc/yum.repos.d/local.repo vim (editors /etc/yum.repos.d/local.repo )
[local] (warehouse name)
= local name (warehouse name)
baseurl = ftp: //192.168.203.4 ( local address ) / centos7 (designated rpm package position)
= 0 gpgcheck (disable gpg check)
1 = Enabled (enable local yum repository)
Clean All -Y yum (buffer empty)
makecache yum (reconstruction cache)
Yum yum repository configuration 3.centos7 online sources and source EPEL
http://rpm.pbone.net/
http://rpmfind.net/
rpm-Uvhhttps://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
- After completion of the mirror mount and into the /etc/yum.repos.d After you create a folder under the file backup
cd /etc/yum.r*
mkdir a/
mv C* a/
2. Download the new CentOS-Base.repo to /etc/yum.repos.d/ or after downloading files to a virtual machine /etc/yum.repos.dxia under
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3 , after running yum -y clean all clear the cache, run yum makecache generate new cache
[root@bogon yum.repos.d]# yum -y clean all
[root@bogon yum.repos.d]# yum makecache
Installation EPEL source
