redhat/centos-6.3上opennebula-3.8部署

此文章是之前所发布的《利用centos-6.3源实现opennebula-3.2的快速安装部署》一文的升级版。本教程在CentOS-6.3的64位版本和64位版本上测试通过。

1. 网络拓扑

采用了两台物理机作为部署环境:

管理节点+计算节点: 192.168.35.16

计算节点:192.168.35.17

2. 管理节点

2.1 配置网易源

(1)安装完CentOS-6.3后,配置centos-6.3的网易源,/etc/yum.repos.d/新建文件centos.repo,内容如下:

#########################################################################
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

#########################################################################

(2)yum update

注意:如果是redha的ost建议选择N

2.2 管理节点配置(计算节点也执行相同操作)

(1)创建oneadmin用户和属组

# groupadd -g 600 oneadmin
#useradd -u 600 -g oneadmin oneadmin

(2)设置oneadmin用户的密码(这里设为:oneadmin)

# passwd oneadmin

(3)配置oneadmin用户,使其具有sudo权限

#vim /etc/sudoers //在原来的root用户下,增加如下一行

oneadmin ALL=(ALL) NOPASSWD: ALL

(4)配置/etc/hosts文件,添加如下两行

192.168.35.16 node1
192.168.35.17 node2

2.3 配置管理节点和计算节点之间的互信

(1)oneadmin用户无密码ssh登录设置

#su - oneamdin
# ssh-keygen -t dsa #出现提示默认回车不要输入
# cat .ssh/id_dsa.pub >> .ssh/authorized_keys
# chmod 644 ~/.ssh/authorized_keys
# chmod 755 ~/.ssh
#vi ~/.ssh/config
StrictHostKeyChecking no
#chmod 600 ~/.ssh/config
# scp –r ~/.ssh oneadmin@node1:~/
oneadmin@node1's password: #默认oneadmin用户密码
# scp –r ~/.ssh oneadmin@node2:~/
(2)验证ssh无密码登录是否配置成功

#ssh oneadmin@node1 date
#ssh oneadmin@node2 date

如果在不输入密码的情况下正确输出,即表示配置成功。

2.4 管理节点软件安装(root用户下执行如下指令)

# yum install gcc gcc-c++ make openssl-devel flex bison
# yum install ruby ruby-devel ruby-docs ruby-ri ruby-irb ruby-rdoc
# yum install rubygems
# gem install nokogiri rake xmlparser
# yum install scons
# yum install xmlrpc-c xmlrpc-c-devel libxslt
# yum install mysql-server mysql-devel.x86_64 sqlite-devel.x86_64

2.5 管理节点环境变量设置

#su - oneadmin

$ mkdir ~/.one
$ vi ~/.one/one_auth
oneadmin:oneadmin

#su - oneadmin

$ vim ~/.bash_profile
export ONE_LOCATION=/opt/nebula/ONE
export ONE_AUTH=$HOME/.one/one_auth
export ONE_XMLRPC=http://localhost:2633/RPC2
export PATH=$ONE_LOCATION/bin:$PATH:.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:.
2.6 opennebula 编译安装

(1)自行下载opennebula-3.8.3,解压后,执行如下命令:

$cd opennebula-3.8.3

$ scons mysql=yes

2.7 datastore的配置

在管理节点和计算节点上都执行如下操作,意思是:用sdb1作为datastore,可以根据自己实际情况而定

#mkdir /data0

#mount /dev/sdb1 /data0

#chown oneadmin:oneadmin /data0 -R

# su - oneadmin

$ vim share/etc/oned.conf // 修改数据库为mysql,并修改mysql的访问密码

#DB = [ backend = "sqlite" ]


# Sample configuration for MySQL
DB = [ backend = "mysql",
server = "localhost",
port = 0,
user = "root",
passwd = "123456",
]

修改datastores的路径:

DATASTORE_LOCATION = /data0

2.8 opennebula安装

(2)opennebula安装

$exit(退出oneadmin用户到root用户下)

#mkdir /opt/nebula/ONE -p

#chown oneadmin:oneadmin /opt/nebula -R

su - oneadmin

$ cdopennebula-3.8.3

$ ./install -d /opt/nebula/ONE

2.9安装sunstone

$ cd opennebula-3.8.3/share/install_gems/

$sudo ./install_gems sunstone

3. 计算节配置

参见管理节点的配置部分

4. 计算节点软件安装

yum install ruby kvm libvirt

5. 启动opennebula和sunstone

到管理节点,执行:

#su - oneadmin

$ one start

$sunstone-server start

6. 通过浏览器访问opennebula

192.168.35.16:9689

用户名和密码都为: oneadmin
