[opennebula]
name=OpenNebula Community Edition
baseurl=https://downloads.opennebula.io/repo/6.0/CentOS/7/$basearch
enabled=1
gpgkey=https://downloads.opennebula.io/repo/repo.key
gpgcheck=1
repo_gpgcheck=1
EOT
[root@kvm ~]# yum clean all
[root@kvm ~]# yum makecache fast二、配置数据库MySQL
2.1 安装MySQL
[root@kvm ~]# yum install -y https://dev.mysql.com/get/mysql80-community-release-el7-11.noarch.rpm
[root@kvm ~]# vim /etc/yum.repos.d/mysql-community.repo添加以下MySQL源配置信息：
[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

[root@kvm ~]# grep -o 'root@localhost.*' /var/log/mysqld.log | awk 'END{print $NF}'
YoHi(8Fk0m?4
[root@kvm ~]# mysqladmin -uroot -p'YoHi(8Fk0m?4' password 'xiangyu'2.3 创建项目用户和库
mysql> CREATE DATABASE 'opennebula' default charset 'utf8';
mysql> CREATE USER 'oneadmin' IDENTIFIED BY '123456';
mysql> GRANT ALL PRIVILEGES ON opennebula.* TO 'oneadmin';
mysql> flush privileges;
mysql> SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED; # 设置事务隔离级别三、安装配置前端包
[root@kvm ~]# yum -y install epel-release
[root@kvm ~]# yum -y install centos-release-scl-rh
# 修改MySQL 下载包
[root@kvm ~]# yum -y install opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow opennebula-provisionls opennebula-node-kvm
# 配置前端使用mysql数据库
[root@kvm ~]# vim /etc/one/oned.conf
DB = [ BACKEND = "mysql",SERVER = "localhost",PORT = 0,USER = "oneadmin",PASSWD = "QianFeng@123",DB_NAME = "opennebula",CONNECTIONS = 25,COMPARE_BINARY = "no" ]四、设置oneadmin账号密码
[root@kvm ~]# sudo -u oneadmin /bin/sh
sh-4.2$ echo 'oneadmin:changeme123' > /var/lib/one/.one/one_auth
sh-4.2$ exit
# 修改如下配置
[root@kvm ~]# vim /etc/one/sunstone-server.conf
:public_fireedge_endpoint: http://one.example.com:2616 # one.example.com为当前主机地址
[root@kvm ~]# vim /etc/one/onegate-server.conf
:host: 0.0.0.0
[root@kvm ~]# vim /etc/one/oned.conf
ONEGATE_ENDPOINT="http://one.example.com:5030"
[root@kvm ~]# vim /etc/one/oneflow-server.conf
:host: 0.0.0.0

使用以下命令停止所有 OpenNebula 服务：
[root@kvm ~]# 使用以下命令停止所有 OpenNebula 服务：
systemctl stop opennebula opennebula-scheduler opennebula-hem \opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow \opennebula-guacd opennebula-novnc opennebula-showback.timer \opennebula-ssh-agent opennebula-ssh-socks-cleaner.timer使用以下命令重新启动所有已在运行的 OpenNebula 服务：
[root@kvm ~]# 使用以下命令停止所有 OpenNebula 服务：
systemctl try-restart opennebula opennebula-scheduler opennebula-hem \opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow \opennebula-guacd opennebula-novnc opennebula-ssh-agent六、访问
账号密码查看 /var/lib/one/.one/one_auth oneadmin:changeme123
6.1 设置语言
6.2 创建主机
七、创建网络模板及网络
请为虚拟机网络单独准备一块网卡
网络模板 CLUSTER_IDS = "0" DNS = "8.8.8.8" GATEWAY = "192.168.33.1" NETWORK_ADDRESS = "192.168.33.0" NETWORK_MASK = "255.255.255.0" PHYDEV = "ens35" SECURITY_GROUPS = "0" VN_MAD = "bridge"
八、创建镜像
保存后会自动上传
九、创建虚拟机模板
虚拟机模板 CONTEXT = [NETWORK = "YES",SSH_PUBLIC_KEY = "$USER[SSH_PUBLIC_KEY]" ] CPU = "1" DISK = [IMAGE = "centos7",IMAGE_UNAME = "oneadmin" ] DISK = [IMAGE = "template",IMAGE_UNAME = "oneadmin" ] DISK = [FORMAT = "qcow2",FS = "xfs",SIZE = "10240",TYPE = "fs" ] GRAPHICS = [LISTEN = "0.0.0.0",TYPE = "VNC" ] HOT_RESIZE = [CPU_HOT_ADD_ENABLED = "NO",MEMORY_HOT_ADD_ENABLED = "NO" ] HYPERVISOR = "kvm" INPUTS_ORDER = "" LOGO = "images/logos/centos.png" MEMORY = "2048" MEMORY_UNIT_COST = "MB" NIC = [NETWORK = "vv",NETWORK_UNAME = "oneadmin",SECURITY_GROUPS = "0",SSH = "YES" ] OS = [ARCH = "x86_64",BOOT = "disk0",MACHINE = "pc-i440fx-rhel7.0.0" ] VCPU = "1" VMGROUP = [ROLE = "centos",VMGROUP_ID = "0" ]
十、创建虚拟机
十一、克隆虚拟机
首先，先进行一台虚拟机的安装，并在创建时持久化该虚拟机，使其成为一个模板，待安装完成后，给系统盘另存为镜像模板。
十二、添加其他主机
添加主机方式，将所有node节点配置ssh免密登录，用户为oneadmin，ssh密码自己设置，秘钥位置为/var/lib/one/.ssh/id_rsa.pub
