将以下内容添加到/etc/yum.repos.d/opennebula.repo文件中。
[rootkvm ~]# cat EOT /etc/yum.repos.d/opennebula.repo
[opennebula]
nameOpenNebula Community Edition
baseurlhttps://downloads.opennebula.io/repo/6.0/CentOS/7/$basearch
enabled1
gpgkeyhttps://downloads.opennebula.io/repo/repo.key
gpgcheck1
repo_gpgcheck1
EOT
[rootkvm ~]# yum clean all
[rootkvm ~]# yum makecache fast
二、配置数据库MySQL
2.1 安装MySQL
[rootkvm ~]# yum install -y https://dev.mysql.com/get/mysql80-community-release-el7-11.noarch.rpm
[rootkvm ~]# vim /etc/yum.repos.d/mysql-community.repo
添加以下MySQL源配置信息
[mysql57-community]

2.2 修改MySQL密码
[rootkvm ~]# grep -o rootlocalhost.* /var/log/mysqld.log | awk END{print $NF}
YoHi(8Fk0m?4
[rootkvm ~]# mysqladmin -uroot -pYoHi(8Fk0m?4 password xiangyu
2.3 创建项目用户和库
mysql CREATE DATABASE opennebula default charset utf8;
mysql CREATE USER oneadmin IDENTIFIED BY 123456;
mysql GRANT ALL PRIVILEGES ON opennebula.* TO oneadmin;
mysql flush privileges;
mysql SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED; # 设置事务隔离级别 三、安装配置前端包
[rootkvm ~]# yum -y install epel-release
[rootkvm ~]# yum -y install centos-release-scl-rh
# 修改MySQL 下载包
[rootkvm ~]# yum -y install opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow opennebula-provisionls opennebula-node-kvm
# 配置前端使用mysql数据库
[rootkvm ~]# vim /etc/one/oned.conf
DB [ BACKEND mysql,SERVER localhost,PORT 0,USER oneadmin,PASSWD QianFeng123,DB_NAME opennebula,CONNECTIONS 25,COMPARE_BINARY no ] 四、设置oneadmin账号密码
[rootkvm ~]# sudo -u oneadmin /bin/sh
sh-4.2$ echo oneadmin:changeme123 /var/lib/one/.one/one_auth
sh-4.2$ exit
# 修改如下配置
[rootkvm ~]# vim /etc/one/sunstone-server.conf
:public_fireedge_endpoint: http://one.example.com:2616 # one.example.com为当前主机地址
[rootkvm ~]# vim /etc/one/onegate-server.conf
:host: 0.0.0.0
[rootkvm ~]# vim /etc/one/oned.conf
ONEGATE_ENDPOINThttp://one.example.com:5030
[rootkvm ~]# vim /etc/one/oneflow-server.conf
:host: 0.0.0.0
[rootkvm ~]# systemctl start opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow
[rootkvm ~]# 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
[rootkvm ~]# su - oneadmin -c oneuser show
