salt系列之安裝

 簡介：

 

Salt is:
• a configuration management system, capable of maintaining remote nodes in defined states (for example, ensuring
that specific packages are installed and specific services are running)
• a distributed remote execution system used to execute commands and query data on remote nodes, either individually
or by arbitrary selection criteria

前提：已安裝epel第三方源；

 

1，at master

 

echo "master_IP     master_hostname" >> /etc/hosts
echo "slave_IP     slave_hostname" >> /etc/hosts
yum install salt -y
yum install salt-master -y
yum install salt-minion -y

配置文件所在目錄:/etc/salt

主要包括master,minion

修改master裏面的interface

 

#interface:  0.0.0.0
interface: master_IP

#master: salt
master: master_IP

/etc/init.d/salt-master start

+++++++++++++++++++++++++

2,at client

 

echo "master_IP     master_hostname" >> /etc/hosts
echo "slave_IP     slave_hostname" >> /etc/hosts

3，key 管理

salt-key -L   ----------------查看key全部信息

salt-key -a xxx   -----------批准xxx的認證

salt-key -A   ---------------批准客戶端全部的認證請求

 

4,注意selinux關閉,防火牆端口4505，4506要開啓

-A RH-Firewall-1-INPUT -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 4505 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 4506 -j ACCEPT
