#centos，源准备：使用阿里云的源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

yum clean all && yum makecache

 

#安装saltstack

        #salt-master安装

        wget https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el6.noarch.rpm --no-check-certificate

        rpm -ivh salt-repo-latest-2.el6.noarch.rpm

        yum install -y python

        yum install -y salt-master

 

        #salt-minion安装

        wget https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el6.noarch.rpm --no-check-certificate

        rpm -ivh salt-repo-latest-2.el6.noarch.rpm

        yum install -y python

        yum install -y salt-minion

注意：如果https下载不了，需要改成http下载；同时需要修改.repo文件，把其中的https也改成http。具体见前面文章。

 

#修改配置文件

salt-master不用修改配置文件；

salt-ninion需要修改配置文件：

vi /etc/salt/minion

修改1：

#master: salt 

#把salt字符串改成salt-master的ip地址

修改2：

#id:

#在冒号后面设置minion的id标识；其实可以不设置，这样就用host等标志了，这需要管理规范，比如机器命名较规范等；

 

#给master添加minion节点，使用salt-key命令
