linux Configure Local yum Source Configure Domestic yum Source and Configure epel Source

1. Configure the local yum source

1. Mount the ISO image

mount -o loop /mnt/yum-iso/CentOS-7-x86_64-DVD-1611.iso /mnt/cdrom

2. Configure the yum source file

#iso.repo You must use the .repo End 
[root@node5 ~]# cat /etc/yum.repos.d/iso.repo 
[iso]
name=iso
baseurl=file:///mnt/cdrom
enable=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

# Clear the system of all yum Cache 
[root@node5 yum.repos.d]# yum clean all

# Generate yum Cache 
[root@node5 yum.repos.d]# yum makecache


# Note: 
[iso]						#yum The name of the source, which is the only one on this server 1 Of, used to distinguish different yum Source 			
name= iso					# Right yum Source description information 
baseurl=file:///mnt/cdrom	#yum Path to the source , It can also be FTP(ftp://...) , HTTP(http://...) , local (file:/// The location of the CD mount directory) 
enabled=1					# For 1 Which means that the yum Source; 0 Is disabled 
gpgcheck=0					# For 1 Using public key validation rpm The correctness of the package; 0 Is not checked 
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 # Specify to proceed rpm Verified public key file address 

3. Set up boot to mount iso image file automatically

# In /etc/fstab File, at the end of the 1 Row addition 
[root@node5 ~]# cat /etc/fstab
/dev/VolGroup00/LogVol00 /                    ext3    defaults        1 1
LABEL=/boot             /boot               　 ext3    defaults        1 2
tmpfs                   /dev/shm             tmpfs   defaults        0 0
devpts                  /dev/pts              devpts  gid=5,mode=620  0 0
sysfs                   /sys                  sysfs   defaults        0 0
proc                    /proc                 proc    defaults        0 0
/dev/VolGroup00/LogVol01 swap                 swap    defaults       0 0
/mnt/yum-iso/CentOS-7-x86_64-DVD-1611.iso    /mnt/cdrom           iso9660  loop           0 0

2. Configure the domestic yum source and epel source

1. First back up the original repo file

[root@node5 ~]# cd /etc/yum.repos.d/
[root@node5 yum.repos.d]# mkdir repo_bak
[root@node5 yum.repos.d]# mv *.repo repo_bak/
[root@node5 yum.repos.d]# ls
repo_bak

2. Download the repo file provided by domestic mirror image

[root@node5 yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo
[root@node5 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@node5 yum.repos.d]# ls
CentOS7-Base-163.repo Centos-7.repo repo_bak

# Note: Centos-7.repo It's in the file 1 Sentence: baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
#$releasever Represents the version number of the system, which can be used cat /etc/centos-release View version number 
#[root@node5 yum.repos.d]# cat /etc/centos-release
#CentOS Linux release 7.4.1708 (Core)
#$basearch Represents the processor type, such as x86_64

# Clear the system of all yum Cache 
[root@node5 yum.repos.d]# yum clean all

# Generate yum Cache 
[root@node5 yum.repos.d]# yum makecache

3. Install the epel source

# Installation official epel Source 
[root@node5 yum.repos.d]# yum install -y epel-release

[root@node5 yum.repos.d]# ls
CentOS7-Base-163.repo Centos-7.repo epel.repo epel-testing.repo repo_bak

# Install Ali's epel Source 
[root@node5 yum.repos.d]# wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo

[root@node5 yum.repos.d]# yum clean all

[root@node5 yum.repos.d]# yum makecache

4. View the yum sources available to the system and all yum sources

[root@node5 yum.repos.d]# yum repolist enabled

[root@node5 yum.repos.d]# yum repolist all
