CentOS 7 安装私有平台OpenNebula

[root@kvm ~]# cat << "EOT" > /etc/yum.repos.d/opennebula.repo
[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

cpp 复制代码

[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：

cs 复制代码

[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

[mysql-connectors-community]
name=MySQL Connectors Community
baseurl=http://repo.mysql.com/yum/mysql-connectors-community/el/7/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

[mysql-tools-community]
name=MySQL Tools Community
baseurl=http://repo.mysql.com/yum/mysql-tools-community/el/7/$basearch/
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

2.2 修改MySQL密码

cs 复制代码

[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

cs 复制代码

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

cs 复制代码

[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

cs 复制代码

[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
[root@kvm ~]# systemctl start opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow
[root@kvm ~]# systemctl enable opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow

五、验证安装

5.1 命令行验证安装

cs 复制代码

[root@kvm ~]# su - oneadmin -c "oneuser show"
USER 0 INFORMATION

    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

复制代码

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

复制代码

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
