<p>该配置环境主要是配置haproxy + keepalived负载均衡的高可用，其中haproxy通过轮训的方式连接到后端实际的2台nginx服务器。<br><a id="more"></a><br><strong>salt安装</strong></p>
<p>master节点： yum install epel-release -y yum install salt-master</p>
<p>minion节点： yum install epel-release -y yum install salt-minion</p>
<p><strong>salt基础配置</strong></p>
<p>本例不作详细介绍。</p>
<p>master节点上 vi /etc/salt/master 修改如下：其他均默认。</p>
<pre><code>file_roots:

</code></pre><p>minion节点上 vi /etc/salt/minion 修改如下： 其他均默认。</p>
<pre><code>master: master
</code></pre><p>所有master minion节点启动服务后(systemctl start salt-minion/salt-master)<br>在master执行 salt-key -A 接受所有minion节点的key。相关情况不做详细介绍。</p>
<p>所有节点/etc/hosts 均一致</p>
<pre><code>[root@master ~]# cat /etc/hosts
