OpenNebula云平台之主控端搭建（一）

OpenNebula云平台之主控端搭建

环境介绍：当前使用Centos7系统，本地虚拟机4核4G，ssh默认22

opennebula版本：5.8.1

关闭selinux、关闭防火墙（或自行开放对应端口），该教程基于OpenNebula官方文档进行修改

1、配置yum源（以下二选一）

wlnmp镜像（推荐）

由于官方源速度实在感人，我这里将所需包组，添加到wlnmp一键包镜像源中

rpm -ivh http://mirrors.whsir.com/centos/whsir-release-centos.noarch.rpm

1	rpm -ivh http://mirrors.whsir.com/centos/whsir-release-centos.noarch.rpm

官方源（不推荐，速度过慢）

vi /etc/yum.repos.d/opennebula.repo

1	vi /etc/yum.repos.d/opennebula.repo

[opennebula]
name=opennebula
baseurl=https://downloads.opennebula.org/repo/5.8/CentOS/7/x86_64
enabled=1
gpgkey=https://downloads.opennebula.org/repo/repo.key
gpgcheck=1
#repo_gpgcheck=1

[opennebula]

name=opennebula

baseurl=https://downloads.opennebula.org/repo/5.8/CentOS/7/x86_64

enabled=1

gpgkey=https://downloads.opennebula.org/repo/repo.key

gpgcheck=1

#repo_gpgcheck=1

2、添加epel源

yum install epel-release

1	yum install epel-release

3、安装OpenNebula

yum install opennebula-server opennebula-sunstone opennebula-ruby opennebula-gate opennebula-flow

1	yum install opennebula-server opennebula-sunstone opennebula-ruby opennebula-gate opennebula-flow

4、查看当前ruby/gem版本

ruby -v
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

1 2	ruby -v ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

gem -v
2.0.14.1

1 2	gem -v 2.0.14.1

5、升级RubyGems到指定版本

gem sources --add https://mirrors.tuna.tsinghua.edu.cn/rubygems/ --remove https://rubygems.org/
gem update --system 2.1

1 2	gem sources --add https://mirrors.tuna.tsinghua.edu.cn/rubygems/ --remove https://rubygems.org/ gem update --system 2.1

6、安装指定版本的bundler

注意：这里如果你使用了国内镜像，可能会找不到bundler 1.17.3的包

gem install bundler -v 1.17.3

1	gem install bundler -v 1.17.3

7、安装OpenNebula所需的一些额外依赖

/usr/share/one/install_gems

1	/usr/share/one/install_gems

lsb_release command not found. If you are using a RedHat based
distribution install redhat-lsb

Select your distribution or press enter to continue without
installing dependencies.

0. Ubuntu/Debian
1. CentOS/RedHat/Scientific

lsb_release command not found. If you are using a RedHat based

distribution install redhat-lsb

Select your distribution or press enter to continue without

installing dependencies.

0. Ubuntu/Debian

1. CentOS/RedHat/Scientific

根据你当前系统进行选择，我这里输入1

Distribution "redhat" detected.
About to install these dependencies:
* gcc
* rubygem-rake
* libxml2-devel
* libxslt-devel
* patch
* gcc-c++
* sqlite-devel
* curl-devel
* mysql-devel
* openssl-devel
* ruby-devel
* make

Press enter to continue...回车继续，耐心等待完成

8、修改OpenNebula控制台密码

echo "oneadmin:whsir" > /var/lib/one/.one/one_auth

1	echo "oneadmin:whsir" > /var/lib/one/.one/one_auth

9、启动OpenNebula并设置自启

systemctl start opennebula
systemctl start opennebula-sunstone
systemctl enable opennebula
systemctl enable opennebula-sunstone

systemctl start opennebula

systemctl start opennebula-sunstone

systemctl enable opennebula

systemctl enable opennebula-sunstone

10、第一次启动后，验证是否可以连接到OpenNebula守护进程

oneuser show

1	oneuser show

如果无法连接到，则会看到如下内容

Failed to open TCP connection to localhost:2633 (Connection refused - connect(2) for "localhost" port 2633)

PS：默认日志位置在/var/log/one

11、访问控制台

http://IP:9869

如果配置正确，则会看到登陆页面

默认登陆用户名是oneadmin

密码是刚才设置的whsir

12、设置OpenNebula语言为中文

至此主控端至此配置完成

PS：OpenNebula端口说明

9869：Sunstone服务器.
29876：VNC代理端口，用于将VNC连接转换和重定向到虚拟机管理程序。
2633：OpenNebula守护进程，主要的XML-RPC API终端
2474：OneFlow服务器，这个端口在使用OneFlow时打开
5030：OneGate服务器，这个端口在使用OneGate时打开
