云平台encalyptus安装配置实践
实验配置
主机1：做front和node,安装clc,cc,nc;
主机2：做node,安装nc
1. 准备工作：
关闭selinux和防火墙
所有节点做时钟同步
#ntpdate pool.ntp.org
用yum安装gcc, java-1.6.0-openjdk, ant,ant-nodeps, dhcp, bridge-utils, httpd, swig等
#yum install scsi-target-utils
2. 安装软件eucalyptus
front: install the -cloud, -walrus, -cc and -sc RPMs
安装基础包

rpm -Uvh eucalyptus-2.0.2-*.i386.rpm \
eucalyptus-gl-2.0.2-1.i386.rpm \
eucalyptus-nc-2.0.2-1.i386.rpm
3、查看系统管理
virsh list
4. 编辑配置文件
在front和node节点上编辑/etc/xen/xend-config.sxp
(xend-http-server yes)
(xend-unix-server yes)
(xend-unix-path /var/lib/xend/xend-socket)
(xend-address localhost)
(network-script network-bridge)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)
(vncpasswd '')
重启xend restart
/etc/init.d/xend restart
frontend节点:
# groupadd libvirt
# vi /etc/libvirt/libvirtd.conf
unix_sock_group="libvirt"
unix_sock_ro_perms="0777"
unix_sock_rw_perms="0770"
auth_unix_ro="none"
auth_unix_rw="none"
# vi /etc/libvirt/qemu.conf
user="eucalyptus"
#chown root:libvirt /var/run/libvirt/libvirt-sock
#chown root:libvirt /var/run/libvirt/libvirt-sock-ro
重启libvirt
#/etc/init.d/libvirtd stop/start
#su eucalyptus -c "virsh list"成功
建立eucalyptus目录
# mkdir /home/eucalyptus
# chown eucalyptus:eucalyptus /home/eucalyptus
# chmod 700 /home/eucalyptus
5. 启动eucalyptus服务
frontend:
# /etc/init.d/eucalyptus-cloud start
# /etc/init.d/eucalyptus-cc status
node:
/etc/init.d/eucalyptus-nc start
Q: 启动cloud start失败，报异常：rg.apache.xerces.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.
A: LANG=zh_CN.utf8;export LANG
# euca_conf --register-walrus 221.7.248.180
ERROR: you need to be on the CLC host and the CLC needs to be running.
修改ssh可以root登录，以下需要输入ssh口令
注册frontend
euca_conf --register-walrus <front end IP address>
euca_conf --register-cluster mycluster 221.7.248.180
euca_conf --register-sc <clustername> <front end IP address>
[root@clc]# brctlshow
bridge name bridgeid STP enabled interfaces
virbr0 8000.000000000000 yes
xenbr0 8000.feffffffffff no peth0
得到xen对应的虚拟网卡的名称，再使用以下命令，设置该网卡的入口连接地址：（假如设置为192.168.1.100）
ifconfig peth0 192.168.1.100
使用命令service network restart刷新网络连接
使用命令ifconfig可以查看网卡peth0的连接地址为192.168.1.100
注册node
euca_conf --register-nodes "<Node 0 IP address> <Node 1 IP address> "
<Node 0 IP address>为运行NC的主机IP地址
--验证注册
euca_conf --list-walruses
euca_conf --list-clusters
euca_conf --list-scs
euca_conf --list-nodes

二. 安装后配置
1. 下载密钥和证书
在node节点上
从8443下载证书，上传到服务器上并解压
在Credentials分栏，点击“CredentialsZIP-file”下的“DownloadCredentials”按钮，下载euca2-admin-x509.zip到本地。
#mkdir ~/.euca
#cd ~/.euca
#chmod 0700 ~/.euca
#chmod 0600 ~/.euca/*
#. ~/.euca/eucarc
2. 修改网络配置
3. 创建image,似乎在一台机器上创建就可以。

修改eucalyptus配置文件
Whenever you make some changes in eucalyptus.conf file, you should cleanstop/cleanstart the CC.
/etc/init.d/eucalyptus-cc cleanstop
/etc/init.d/eucalyptus-cc cleanstart
