CentOS安装OpenNebula（一）

OpenNebula是一个非常成熟的云平台，，十分简单，但是功能十分丰富。它提供了十分灵活的解决方案，让用户能建立并管理企业云和虚拟的数据中心。

OpenNebula是专门为云计算打造的开源系统，用户可以使用Xen、KVM、VMware等虚拟化软件一起打造企业云。利用OpenNebula可以轻松构建私有云、混合云、公开云。

主控端部署：

1、hosts文件做DNS解析。

[root@master ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.17.107 server01 server01.lnmp.com
192.168.17.128 master
192.168.17.129 node1
192.168.17.130 store

将所有的主机上hosts文件进行替换：

[root@master ~]# scp /etc/hosts root@192.168.17.129:/etc/hosts
The authenticity of host '192.168.17.129 (192.168.17.129)' can't be established.
ECDSA key fingerprint is SHA256:4dogA08L5gdfaA69BGekE13kzSuIP2vcRp9rsqYnpn0.
ECDSA key fingerprint is MD5:93:34:b9:61:03:cd:00:92:b9:91:3d:b6:6c:7a:84:95.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.17.129' (ECDSA) to the list of known hosts.
root@192.168.17.129's password:

[root@master ~]#

[root@master ~]#

2、关闭SELINUX：

[root@master ~]# setenforce 0
setenforce: SELinux is disabled
[root@master ~]#
[root@master ~]# sed -i '/^SELINUX=/cSELINUX=disabled' /etc/selinux/config

3、防火墙配置：

为了能使OpenNebula正常工作，还必须配置系统防火墙开放相应的端口。目前采取的是关闭防火墙的做法。

[root@master ~]# systemctl stop firewalld && systemctl disable firewalld

4、软件源的配置：

[root@master yum.repos.d]# vim opennebula.repo

[root@master yum.repos.d]# cat opennebula.repo
[opennebula]
name=opennebula
baseurl=https://downloads.opennebula.org/repo/5.6/CentOS/7/x86_64
enabled=1
gpgkey=https://downloads.opennebula.org/repo/repo.key
gpgcheck=1

5、安装epel源：epel源将提供一些额外的软件包。

[root@master ~]# yum install -y epel-release

6、安装依赖软件包。

[root@master ~]# yum install -y gcc-c++ sqlite-devel curl-devel mysql-devel ruby-devel make

7、安装OpenNebula主控依赖。

[root@master ~]# yum -y install opennebula-server opennebula-sunstone opennebula-ruby opennebula-gate opennebula-flow

8、安装OpenNebula主控额外依赖和主程序：

先配置下国内源：

[root@master one]# gem sources -r https://rubygems.org/ -a https://gems.ruby-china.com/
https://gems.ruby-china.com/ added to sources
https://rubygems.org/ removed from sources


[root@master one]# gem install bundler --version '< 2'

Nothing to do
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as
root will break this application for all non-root users on this machine.

这个地方要有耐心等待，时间稍长。在获取程序和安装程序的过程中不要中断进程。

9、修改默认的oneadmin密码（这个账号密码用于登录OpenNebula的控制面板）：

[root@master ~]# echo "oneadmin:910zxq" > /var/lib/one/.one/one_auth

10、启动OpenNebula：

[root@master ~]# systemctl start opennebula
[root@master ~]# systemctl start opennebula-sunstone

检查两个程序的运行状态：

[root@master one]# systemctl status opennebula

看到两个程序都运行正常。
