PaaS基础平台配置
PaaS基础平台配置1、操作系统基本配置请重新下载“PaaS基础平台配置”，主要修正了安全组防火墙配置。按照新的文档做，可以不用一直开着服务器了。PaaS基础平台搭建好后，可以关闭两台云主机，进而关闭服务器，下次开机可以继续做。 （1）使用admin用户新建云主机类型PaaS，虚拟内核为1个，内存为2048MB，根磁盘为50GB。 （2）启动云主机paas，作为PaaS的Broker。云主机类型选择PaaS。 （3）启动云主机node，作为PaaS的Node。云主机类型选择PaaS。 （4）编辑安全组default规则，增加ALL ICMP、ALL TCP和ALL UDP三条规则。（原有的SSH规则可以删除）。 （5）查看云主机IP地址（这两个地址是自动获取的），使用SSH登录到云主机。 注意：这里的两台云主机IP地址为192.168.1.2和192.168.1.3，比赛时需要根据实际情况调整后续相关配置。 （6）修改两台云主机的hostname。# vi /etc/sysconfig/networkNETWORKING=yesHOSTNAME=paasNOZEROCONF=yes # vi /etc/sysconfig/networkNETWORKING=yesHOSTNAME=nodeNOZEROCONF=yes （7）修改两台云主机的hosts。# vi /etc/hosts127.0.0.1localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.1.2 paas192.168.1.3 node #

vi /etc/sysconfig/selinuxSELINUX=enforcing （10）配置YUM编辑/etc/fstab，将先电PaaS v1.2光盘ISO挂载到控制节点的FTP目录/var/ftp/paas中。在两台云主机上配置YUM：删除/etc/yum.repos.d路径下的所有repo文件，以下为YUM源配置。# lsopenshift-base.repoopenshift-epel.repoopenshift-origin-deps.repoopenshift-origin.repo # catopenshift-base.repo name=openshift-basebaseurl=ftp://192.168.1.1/paas/openshift-basegpgcheck=0 # catopenshift-epel.repo name=Extra Packages for Enterprise Linux 6- $basearchbaseurl=ftp://192.168.1.1/paas/openshift-epelexclude=*passenger* nodejs*failovermethod=prioritygpgcheck=0 #

paas-pre-host.sh # paas-pre-node.sh （5）配置域名服务(DNS)在Broker节点执行脚本paas-pre-broker.sh # paas-pre-broker.sh 样题要求：验证DNS配置：# nslookup> serverDefault server: 127.0.0.1Address: 127.0.0.1#53> paas.example.comServer: 127.0.0.1Address:127.0.0.1#53 Name: paas.example.comAddress: 192.168.1.2> exit #

paas-install-mongodb.sh （7）安装和配置ActiveMQ消息管理服务在Broker节点执行脚本paas-install-activemq.sh # paas-install-activemq.sh # vi /etc/activemq/jetty.xml将这一行中的127.0.0.1，更改为0.0.0.0。 <propertyname="host" value="127.0.0.1" />更改后的配置： <propertyname="host" value="0.0.0.0" /> 重启服务：# service activemq restart 样题要求：ActiveMQ消息中间件验证浏览器访问Broker的ActiveMQ服务，输入用户名admin，密码000000。 （8）安装Puppet Mcollective Client端在Broker节点执行脚本paas-install-mcollective.sh # paas-install-mcollective.sh （9）安装PaaS Broker配置身份服务在Broker节点执行脚本paas-install-broker.sh # paas-install-broker.sh 在脚本执行过程中，要求输入RSA key加密随机数时，输入2次回车，即不配置RSA key加密随机数。 （10）安装PaaS Broker Plugin在Broker节点执行脚本paas-install-broker-plugins.sh #paas-install-broker-plugins.sh 访问Broker的API json服务验证安装是否正确：# curl -u admin:000000http://localhost:8080/broker/rest/api.json 执行后返回APIs的JSON描述。 （11）安装PaaS Broker Web Console在Broker节点执行脚本paas-install-webconsole.sh # paas-install-webconsole.sh （12）安装Node容器节点Broker节点执行脚本paas-node-install-controller.sh，node节点执行脚本paas-node-install-node.sh #paas-node-install-controller.sh # paas-node-install-node.sh输入yes，输入paas节点root用户的密码000000。安装过程较长。 （13）配置多租户在Node节点执行脚本paas-config-multi-tenancy.sh # paas-config-multi-tenancy.sh 安装完成后，重新启动Node节点。 编辑浏览器所在Windows主机的C:\Windows\System32\drivers\etc\hosts，添加配置：192.168.1.2 paas.example.com或将Windows主机的DNS服务器指向paas节点。 登录http://paas.example.com查看网页是否正确，输入用户名admin，密码000000。（对应/etc/xiandian/config.ini中的配置。） 图文请见附件。百度云附件：部署PaaS应用（Part0）PaaS基础平台配置.pdf版主大人啊！python怎么部署呢？？
