centos7.5部署salt及其组件、salt-master、salt-minion报python版本问题

背景：

yum安装salt、salt-master、salt-minion

报错：

部署步骤（失败）：

安装epel-release包：yum -y install epel-release
yum -y install salt salt-master salt-minion
报错：balabala。。。

原因：

release与python的依赖关系矛盾

解决办法：

[root@kafka-02 ~]# cd /etc/yum
[root@kafka-02 yum.repos.d]# vim saltstack.repo
[saltstack-repo]
name=SaltStack repo for RHEL/CentOS $releaseverbaseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latestenabled=1gpgcheck=1gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/SALTSTACK-GPG-KEY.pub

如果上述方法还是不能解决,可以尝试：
1.python多版本公用办法（自行百度，有很多教程）
2.用python的pip替代yum去下载salt、salt-master组件
