官网安装文档

一、安装步骤

一、关闭SE
- SELINUX=disabled

二、配置epel源地和opennebula源

centos7

cat << "EOT" > /etc/yum.repos.d/opennebula.repo
[opennebula]
name=opennebula
baseurl=https://downloads.opennebula.org/repo/5.10/CentOS/7/$basearch
enabled=1
gpgkey=https://downloads.opennebula.org/repo/repo.key
gpgcheck=1
repo_gpgcheck=1
EOT

centos8

cat << "EOT" > /etc/yum.repos.d/opennebula.repo
[opennebula]
name=opennebula
baseurl=https://downloads.opennebula.org/repo/5.10/CentOS/8/$basearch
enabled=1
gpgkey=https://downloads.opennebula.org/repo/repo.key
gpgcheck=1
repo_gpgcheck=1
EOT

三、安装相关主控相关依赖包

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

四、Ruby 运行环境安装（V5.10版本以后可选）

查看：
ls -lad /usr/share/one/gems*
lrwxrwxrwx 1 root root    9 Aug 13 11:41 /usr/share/one/gems -> gems-dist
drwxr-xr-x 9 root root 4096 Aug 13 11:41 /usr/share/one/gems-dist

自动修复：
test -L /usr/share/one/gems && unlink /usr/share/one/gems
/usr/share/one/install_gems

手动修复：
sqlite3 development library
mysql client development library
curl development library
libxml2 and libxslt development libraries
ruby development library
gcc and g++
make
以上安装包

五、mysql数据库配置

一、建立用户
GRANT ALL PRIVILEGES ON opennebula.* TO 'oneadmin' IDENTIFIED BY '<thepassword>';

二、配置事务隔离级别
SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED;

三、配置oned.configuration
# Sample configuration for MySQL
   DB = [ backend = "mysql",
   server  = "localhost",
   port    = 0,
   user    = "oneadmin",
   passwd  = "<thepassword>",
   db_name = "opennebula" ]
四、按期清理索引
alter table vm_pool drop index ftidx;
alter table vm_pool add fulltext index ftidx (search_token);
五、虚拟机自定义配置

六、启动OpenNebula

一、使用 oneadmin 用户
su oneadmin
二、修改默认密码
echo "oneadmin:mypassword" > ~/.one/one_auth
三、启动
systemctl start opennebula
systemctl start opennebula-sunstone
四、出错验证Ruby环境是否有问题

七、验证安装

一、命令：oneuser show
输出：
USER 0 INFORMATION
ID              : 0
NAME            : oneadmin
GROUP           : oneadmin
PASSWORD        : 3bc15c8aae3e4124dd409035f32ea2fd6835efc9
AUTH_DRIVER     : core
ENABLED         : Yes

USER TEMPLATE
TOKEN_PASSWORD="ec21d27e2fe4f9ed08a396cbd47b08b8e0a4ca3c"

RESOURCE USAGE & QUOTAS
二、网页
http://<frontend_address>:9869
三、错误日志
/var/log/one/sunstone.log
/var/log/one/sunstone.error

五、端口说明
Port	Description
9869	Sunstone server.
29876	VNC proxy port, used for translating and redirecting VNC connections to the hypervisors.
2633	OpenNebula daemon, main XML-RPC API endpoint.
2474	OneFlow server. This port only needs to be opened if OneFlow server is used.
5030	OneGate server. This port only needs to be opened if OneGate server is used.
端口均可以自定义配置，或者代理。

八、后续步骤

一、重置密码
oneuser passwd 0 <PASSWORD>
echo 'oneadmin:PASSWORD' > /var/lib/one/.one/one_auth

二、Opennedula 扩展应用

OneFlow

说明

用于将多个虚拟机应用程序定义和管理为单个实体。OneFlow还让您为应用程序组件定义依赖关系和自动扩展策略。

三、应用

启动：
service opennebula-flow start
日志：
/var/log/one/oneflow.error
/var/log/one/oneflow.log

三、Opennedula node节点安装

一、要添加OpenNebula存储库，请以root用户身份执行如下操做：

cat << “ EOT” > /etc/yum.repos.d/opennebula.repo
 [ opennebula ] 
名称= opennebula
 baseurl = https://downloads.opennebula.org/repo/5.10/CentOS/7/ $ basearch 
enabled = 1 
gpgkey = https://downloads.opennebula.org/repo/repo.key
 gpgcheck = 1 
repo_gpgcheck = 1 
EOT

二、安装软件

sudo yum install opennebula-node-kvm
sudo systemctl restart libvirtd

qemu-kvm安装

sudo yum install  centos-release-qemu-ev
sudo yum install qemu-kvm-ev

三、禁用SElinux

vim /etc/selinux/config
SELINUX=disabled

四、配置无密码的SSH

一、前端服务器之前端服务器，节点服务器为参数，生成known_hosts文件

ssh-keyscan <frontend> <node1> <node2> <node3> ... >> /var/lib/one/.ssh/known_hosts

二、服务器分发文件

scp -rp /var/lib/one/.ssh <node1>:/var/lib/one/
scp -rp /var/lib/one/.ssh <node2>:/var/lib/one/
scp -rp /var/lib/one/.ssh <node3>:/var/lib/one/

###　FAQ

选择导入虚拟机后，会修改默认的/etc/libvirt/qemu.conf
还原为
user = "qemu"
group = "qemu"
就能够继续使用命令行启动
