环境：
纯净Linux系统，未搭建安装任何环境和程序
操作系统：Centos8
python版本：python3
一、配置yum源
（1）进入/etc/yum.repos.d目录下，将Centos-Base.repo备份
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
（2）本次配置清华大学镜像站里的yum源：https://mirrors.cnnic.cn/help/centos/
将CentOS-Base.repo内的内容替换掉：
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [BaseOS] name=CentOS-$releasever - Base baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/BaseOS/$basearch/os/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial [AppStream] name=CentOS-$releasever - AppStream baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/AppStream/$basearch/os/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial [PowerTools] name=CentOS-$releasever - PowerTools baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/PowerTools/$basearch/os/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=PowerTools&infra=$infra enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/extras/$basearch/os/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/centosplus/$basearch/os/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
（3）清除缓存
yum clean all
yum makecache
二、安装ansible
（1）第一步配置epel:
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
或者
yum install epel-release
（2）安装ansible
yum install -y ansible
三、ansible简单介绍
（1）配置文件：
ansible的配置文件在/etc/ansible目录下：（分别是ansible.cfg、hosts、roles）
[root@localhost ansible]# ll
总用量 24
-rw-r--r--. 1 root root 19985 2月 14 06:44 ansible.cfg
-rw-r--r--. 1 root root 1016 2月 14 06:44 hosts
drwxr-xr-x. 2 root root 6 2月 14 06:44 roles
