网易163源配置更新
增加163repo
# vi /etc/yum.repo.d/163.repo
[163.repo]
name=mirrors.163.com.repo
baseurl=http://mirrors.163.com/centos/7/os/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
清除缓存生成缓存
yum clean all
yum make cache
CentOS 7 配置163**源**
具体的操作步骤：
1、打开终端，输入su指令切换到aoao.club用户：su
2、切换到系统yum源的目录下，即：cd /etc/yum.repos.d
3、备份系统默认yum源（也可直接删除）：mv CentOS-Base.repo CentOS-Base.repo.backup
4、下载163网易的yum源：wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
5、yum源更新：yum clean all && yum makecache
6、完成
排除部分组件
yum update --exclude=kernel
yum**添加源**
yum -y install yum-utils
$ sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
可以选择国内的一些源地址：
阿里云
$ sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
清华大学源
$ sudo yum-config-manager \
--add-repo \
https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
一、私有yum源yum源创建过程
1.**创建工作目录**
mkdir /aoao.club/epeltest mkdir /aoao.club/epeltest/Packages
2.**将相应的rpm包放到/aoao.club/epeltest/Packages 目录**
采用yum下载软件包，以ansible为例：
（1）安装epel yum源，方便下载ansible
yum -y install epel-release
（2）安装createrepo，用于制作yum源
yum -y install createrepo
（3）通过yum下载ansible相关的软件包，存放到/aoao.club/epeltest/Packages目录
yum install ansible --downloadonly --downloaddir=/aoao.club/epeltest/Packages
3.**执行命令创建yum源**
createrepo /aoao.club/epeltest/
命令执行后将在/aoao.club/epeltest目录下生成repodata，该目录存储的是yum源的信息。至此，yum源已制作完毕，通过repo文件制定/aoao.club/epeltest/目录即可进行本地安装ansible。
二、将自制yum源制作ISO镜像
1.**安装mkisofs**
yum -y install mkisofs
2.**将自制的yum源制作iso镜像**
mkisofs -r -o epel7.iso /aoao.club/epeltest
三、通过本地yum源安装ansible
提示：将章节一中/aoao.club/epeltest目录拷贝到需要安装ansible机器，并配置yum源配置文件即可。本节重点介绍如何挂载iso文件作为本地yum源。
1.**将章节二中制作的iso文件拷贝到目标机器，并挂载**
#挂载目录可自行定义 mount -o loop epel7.iso /mnt
2.**配置yum源**
（1）将/etc/yum.repos.d/ 目录中的文件备份，然后删除所有的repo文件。此步骤主要是为了防止其他repo对测试有干扰
（2）创建repo文件，如local.repo，内容如下：
[epel] name=epel baseurl=file:///mnt/ gpgcheck=0 enabled=1
（3）清除yum源缓存
yum clean all yum makecache
3.**安装程序ansible**
yum install ansible
1，强制卸载所有包
rpm -qa|grep yum|xargs rpm -e --nodeps
2,查看是否卸载完全
rpm -qa|grep yum
3，下载相关的rpm插件，
mkdir software
cd software
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-chardet-2.2.1-3.el7.noarch.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-kitchen-1.1.1-5.el7.noarch.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-10.el7.noarch.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/rpm-4.11.3-43.el7.x86_64.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/rpm-build-libs-4.11.3-43.el7.x86_64.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/rpm-python-4.11.3-43.el7.x86_64.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/wget-1.14-18.el7_6.1.x86_64.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-3.4.3-167.el7.centos.noarch.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-53.el7.noarch.rpm
wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-53.el7.noarch.rpm
4，安装所有插件
rpm -ivh *.rpm --force --nodeps
5，修改yum配置
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
6，修改CentOS-Base.repo文件
vi /etc/yum.repos.d/CentOS-Base.repo
把
$releasever全局替换成7执行
:%s/$releasever/7/g
mirrors.aliyuncs.com 全部改成 mirrors.aliyun.com 不然后面会报错，mirrors.aliyuncs.com这个域名好像有问题，具体情况不明:
:s/aliyuncs/aliyun/g
:wq 保存退出
7,#yum clean all
#yum makecache 生成元数据缓存
测试
yum -y install tree 用tree查看文件夹结构
下面分享一下利用 iso 镜像搭建本地 yum 仓库的简单步骤：
一、准备工作
下载或拷贝 CentOS 或 RedHat 的 iso 镜像到本地，比如 /usr/local/src/CentOS-6.4-x86_64-bin-DVD1.iso
二、挂载 iso 镜像
①、新建挂载目录：
mkdir -p /mnt/cdrom1
②、直接编辑/etc/fstab 文件（编辑请请备份），在后面添加：
#挂载iso
/usr/local/src/CentOS-6.4-x86_64-bin-DVD1.iso /mnt/cdrom1 iso9660 loop,defaults 0 0
②、执行 mount -a 自动检测并激活挂载，若未报错，执行 df -h 即可看到结果。
三、配置并刷新 yum 仓库
①、新增 yum 配置文件：
Ps：完全离线使用，新增之前建议先删除(移走)所有在线 yum 源：mv -f /etc/yum.repos.d/* /home/
vim /etc/yum.repos.d/local.repo
粘贴以下内容，第 3 行表示 iso 挂载目录：
[local-yum]
name=Local Repository
baseurl=file:///mnt/cdrom1
enabled=1
gpgcheck=0
②、刷新查看 yum 是否生效：
yum clean all && yum list
以上要是没要报错，那么本地 yum 仓库就搭建好了，就可以使用【 yum install 软件名】来安装所需软件，而不需要联网了。
四、多个 iso 镜像的做法：
Ps：下面只说有区别的部分。
①、挂载的时候，有几个 iso 就挂载几个，比如 CentOS 6.4 有 2 个 iso：
#创建2个挂载目录
mkdir -p /mnt/cdrom{1,2}
#挂载iso
/usr/local/src/CentOS-6.4-x86_64-bin-DVD1.iso /mnt/cdrom1 iso9660 loop,defaults 0 0/usr/local/src/CentOS-6.4-x86_64-bin-DVD2.iso /mnt/cdrom2 iso9660 loop,defaults 0 0
#激活挂载
mount -a
②、编辑 yum 配置文件的时候，路径需要改成上一级路径，比如：
[local-yum]
name=Local Repository
baseurl=file:///mnt/
enabled=1
gpgcheck=0
③、使用 createrepo 命令创建 yum 仓库：
cd /mnt/
createrepo .
最经比较忙， 还没来得及截图，先凑合发布了，等有空了再来补充。

# If the mirrorlist= does not work for you, as a fall back you can try the
