前言

openstack如何部署，怎样使用，在官网上很是详细，即使是linux小白用户，按照官网上一步一步做起来，还是可以让云平台跑起来的。使用linux是离不开shell，我们可以使用shell来自动化部署openstack平台。其实，说是自动化其实也不是，只是把繁琐的配置文件，openstack service，sql等使用脚本来直接拷贝进去，使之生效。这样能够很方便的让一个有一个openstack平台搭建起来，提高工作效率，缩短项目周期。

手动干预项

使用本地源，能够非常快速的安装openstack依赖包，这是利器，推荐所有使用openstack的，事先搭建好。

  • 准备ubuntu16.04.2 : controller(1个)，compute(1个)，cinder(1个)，swift（1个）
  • 修改这4台主机的hosts
    hosts:
10.0.0.11 controller
10.0.0.21 compute1
10.0.0.31 block1
10.0.0.41 swift
  • 修改这4个主机的hostname
    • controller、compute1、block1、swift

controller 自动部署脚本

  • 配置混杂网卡代码块
#!/bin/sh
set -x
readonly interface_name=ens7 
echo "begin config menual interface"
# 下面这5行是删除符合条件的内容，防止重复添加
sed -i "/^auto\\$interface_name/d" /etc/network/interfaces
sed -i "/^iface $interface_name inet manual/d" /etc/network/interfaces
sed -i '/^up*/d' /etc/network/interfaces
sed -i '/^down*/d' /etc/network/interfaces
sed -i '/^# The provider*/d' /etc/network/interfaces
# 添加网卡
sed -i '$a\  ' /etc/network/interfaces
sed -i '$a\# The provider network interface' /etc/network/interfaces
sed -i "\$a\auto $interface_name" /etc/network/interfaces
sed -i "\$a\iface $interface_name inet manual" /etc/network/interfaces
sed -i '$a\up ip link set dev $IFACE up' /etc/network/interfaces

echo 'y')| apt-get install chrony
echo '时间同步，同步服务器需要手动设置'
sed -i -e "s/^allow.*/allow = $chrony_allow/" ./conf/chrony.conf

总结

  • 安装包的格式
(echo 'y'
echo 'y')|apt-get install ...
  • sed -i -e 的用法…删除一行文字，追加文件，替换文件
    • 注意特殊字符的处理
  • set -x 和 set +x 等 set 的使用
  • shell 语法初步学习
