秒云安装
<h1>1.基础环境准备</h1>
<h2>1.1安装CentOS 7操作系统</h2>
<p>注意：
（1）/var/lib/docker目录需要预留大于200GB的空间
（2）CentOS7系统升级</p>
<pre><code class="language-bash">[root@zyetaio ~]# yum update -y </code></pre>
<p>（3）修改主机名
确保唯一性(主机名不能有下划线、大写字母)</p>
<h2>1.2升级内核版本到4.15</h2>
<p>秒云要求CentOS7内核版本需在4.10及以上版本。
检查内核版本号：uname -r
升级内核操作，参见《1_基础环境准备\1.2_升级内核版本到4.15\rpm包升级内核法》</p>
<pre><code class="language-bash">[root@zyetaio ~]# rpm -ivh /usr/src/*.rpm
[root@zyetaio ~]# grub2-set-default
[root@zyetaio ~]# reboot
[root@zyetaio ~]# uname -r</code></pre>
<p>说明：当有kernel-headers相关报错时，先删除。</p>
<pre><code class="language-bash">rpm -e --nodeps kernel-headers</code></pre>
<h2>1.3安装18.09.2版本Docker</h2>
<p>秒云支持docker-ce最新版，安装最新版即可。</p>
<h3>1.3.1安装前检查基础环境</h3>
<p>（1）关闭selinux、firewalld</p>
<pre><code class="language-bash">[root@zyetaio ~]# systemctl stop firewalld
[root@zyetaio ~]# systemctl disable firewalld
[root@zyetaio ~]# sed -i 's/SELINUX=enforcing/SELINUX=disable/g' /etc/selinux/config</code></pre>
<p>（2）检查CentOS7内核版本</p>
<pre><code class="language-bash">[root@zyetaio ~]# uname –r
4.15.18</code></pre>
<p>（3）检查并配置ipv4，将内容修改为如下
cat /usr/lib/sysctl.d/00-system.conf</p>
<pre><code class="language-bash">net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-arptables = 0
net.ipv4.ip_forward = 1</code></pre>
<p>保存并重启网卡</p>
<pre><code class="language-bash">[root@zyetaio ~]# systemctl restart network</code></pre>
<h3>1.3.2上传并安装docker-ce</h3>
<p>docker安装文件在（1_基础环境准备\1.3_安装18.09.2版本Docker）目录下，安装时，用root用户在一体机上执行如下命令：</p>
<pre><code class="language-bash">[root@zyetaio ~]# yum localinstall -y containerd.io-1.2.2-3.3.el7.x86_64.rpm docker-ce-18.09.2-3.el7.x86_64.rpm docker-ce-cli-18.09.2-3.el7.x86_64.rpm</code></pre>
<h3>1.3.3启动docker并设置开机启动</h3>
<pre><code class="language-bash">[root@zyetaio ~]# systemctl start docker
[root@zyetaio ~]# systemctl enable docker</code></pre>
<h2>1.4创建easytong用户</h2>
<p>执行创建easytong组和easytong用户：</p>
<pre><code class="language-bash">[root@zyetaio ~]# groupadd -g 2001 easytong
[root@zyetaio ~]# useradd -u 2001 -g 2001 easytong
[root@zyetaio ~]# echo "easytong:310012" | chpasswd</code></pre>
<p>添加到docker用户组里</p>
<pre><code class="language-bash">[root@zyetaio ~]# usermod -aG docker easytong</code></pre>
<h2>1.5设置easytong用户sudo免密操作</h2>
<p>为安全考虑，一般生产环境中，不使用root用户直接运行程序或进行操作，这里设置easytong用户sudo免密使用，可以安装部署秒云、添加集群节点操作，否则就需要用root来进行操作。具体设置方法，在/etc/sudoers中添加如下内容：</p>
<pre><code class="language-bash">easytong ALL=(ALL) NOPASSWD:ALL</code></pre>
<h1>2、秒云安装</h1>
<h2>2.1 上传秒云安装包并解压</h2>
<p>把秒云安装包miaoyun-20.03.1.tar，上传至用户目录下；</p>
<pre><code class="language-bash">md5sum miaoyun-20.03.1.tar</code></pre>
<p>解压：</p>
<pre><code class="language-bash">tar -xvf miaoyun-20.03.1.tar</code></pre>
<p>由于有些网络不好，上传过程可能会导致文件传轮不正确，可进行验证</p>
<pre><code class="language-bash">md5sum miaoyun-boot-20.03.1.tar
md5sum miaoyun-images-20.03.1-FULL.tar</code></pre>
<p>把输出结果与文件md5sum.txt中的内容进行比对正确性。</p>
<h2>2.2 执行安装</h2>
<pre><code class="language-bash">./miaoyun_deploy_offline.sh</code></pre>
<h2>2.3 安装过程</h2>
<pre><code class="language-bash">[easytong@docker-study ~]$ time sudo ./miaoyun_deploy_offline.sh

<h2>3. 登录秒云</h2>
<p>从上面安装过程中，提示如何访问秒云
打开浏览器，在地址栏中输入：</p>
<pre><code class="language-bash">https://172.16.3.239</code></pre>
<p>选择 标准用户，用户名/密码：</p>
<pre><code class="language-bash">admin/admin</code></pre>
<h2>4. 秒云配置</h2>
<p>登录秒云平台（默认用户名/密码：admin/admin）
1． 点击“主机池”菜单，打开主机列表页面，点击“添加主机”按钮，将所有主机添加到主机池中：
2． 点击“集群”菜单，打开集群列表页面，点击“创建新集群”按钮，创建集群“我的易通”：
网络设置：网络模型：flannel，主机起讫端口范围：1-65535
3． 将主机加入集群：
需要注意的是：先添加集群管理节点，待集群管理节点状态就绪了之后，再批量添加其他计算节点。
4． 点击“域管理”菜单，打开域列表页面，点击 默认域，进入默认域详情页面，将集群绑定给默认域：
5.进入“域视角”，点击“项目”菜单，进入“项目(default)”，点“编辑集群”按钮进入，进行节点分配。</p>
