标签:运维人员搭建服务器的常用技术

  

 

 1)硬件环境  Windowsxp

    2)软件环境  CentOS6864   

    3)项目名称  我叫超级无敌变态实验

    4)项目描述

DNS主从+DNS视图+两个Squid反向代理+Nginx负载均衡+

Httpd/Nginx/Tomcat部署+ISCSI后端存储

    5)配置步骤 

A、用Visio规划好整体架构

      BDNS主从DNS视图用squid1squid2做两个网页验证

CISCSI后端存储先做双王再导入第三个节点

D、部署Httpd/Nginx/Tomcat 挂载访问网页验证存储

E、部署nginx负载均衡卸载网页根写上不同的内容验证

F、配置两个反向代理用客户端验证

 

 

注意:因硬件环境限制分别用DNS1DNS2,作电信和网通的客户端。

到此DNS主从加视图完事

 

开启squid1代理和squid2代理做一个简单的http网页测试

配置hosts文件主机名ip地址时间同步

Squid1代理

[root@squid1~]# hostname squid

[root@squid1~]# vim /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=squid

退出重新连接

[root@squid1 ~]# scp 172.16.27.10:/etc/hosts /etc/hosts

[root@squid1 ~]# ntpdate dns1

[root@squid1 ~]# yum install httpd -y

[root@squid1 ~]# echo "wo shi dianxin" >>  /var/www/html/index.html

[root@squid1 ~]# /etc/init.d/httpd start

Starting httpd: httpd: Could not reliably determine the server‘s fully qualified domain name, using 172.16.27.40 for ServerName

                                                           [  OK  ]

Squid2代理

[root@lee ~]# hostname squid2

[root@lee ~]# vim /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=nginx

退出重新连接

[root@squid2 ~]# scp 172.16.27.10:/etc/hosts /etc/hosts

[root@squid2 ~]# ntpdate dns1

[root@squid2~]# yum install httpd -y

[root@squid2 ~]# echo "wo shi wangtong" >> /var/www/html/index.html

[root@squid2 ~]# /etc/init.d/httpd start

Starting httpd: httpd: Could not reliably determine the server‘s fully qualified domain name, using 172.16.27.50 for ServerName

                                                           [  OK  ]

分别用dns1 dns2访问www.lee.com验证

DNS1

[root@dns1 ~]# yum install elinks -y

[root@dns1 ~]# elinks --dump www.lee.com

   wo shi dianxin

DNS2

[root@dns2 ~]# yum install elinks -y

[root@dns2 ~]# elinks --dump www.lee.com

   wo shi wangtong

关闭代理的网页防止以后实验干扰

[root@squid1 ~]# /etc/init.d/httpd stop

Stopping httpd:                                            [  OK  ]

[root@squid2~]# /etc/init.d/httpd stop

Stopping httpd:                                            [  OK  ]

 

先做存储

修改主机名、ip地址、时间同步、hosts文件。

先实现双王模式集群  再添加第三个节点

 

存储端导出存储

[root@scsi ~]# yum install scsi-target-utils -y

[root@scsi ~]# fdisk /dev/sda

导出的存储大小为20G

/dev/sda5:20G

[root@scsi ~]# partx -a /dev/sda

[root@scsi ~]# ls /dev/sda*

[root@scsi ~]# vim /etc/tgt/targets.conf

 41 <target iqn.2017-10.com.up.storage:lee20G>

 42     backing-store /dev/sda5

 43 </target>

[root@scsi ~]# /etc/init.d/tgtd start

Starting SCSI target daemon:                               [  OK  ]

[root@scsi ~]# chkconfig tgtd on

[root@scsi ~]# tgt-admin -s

Target 1: iqn.2017-10.com.up.storage:lee20G

看一下是否导出

[root@nginxf conf]# nginx -t

nginx: the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/webserver/nginx/conf/nginx.conf test is successful

[root@nginxf conf]# nginx -s reload

验证

node3上写网页内容把挂载的分区卸载

[root@node3 ~]# umount /usr/local/tomcat7/webapps/ROOT/

[root@node3 ~]# echo lee >> /usr/local/tomcat7/webapps/ROOT/index.html

[root@node3 ~]# /usr/local/tomcat7/bin/shutdown.sh

等一会在开启

[root@node3 ~]# /usr/local/tomcat7/bin/startup.sh

[root@nginxf conf]# curl nginxf

lee

[root@nginxf conf]# curl nginxf

we are cluster

[root@nginxf conf]# curl nginxf

lee

[root@nginxf conf]# curl nginxf

we are cluster

负载均衡成功

 

部署安装代理服务器squid1squid2

修改主机名、ip地址、时间同步、hosts文件

Squid1

[root@squid1 ~]# yum install squid -y

[root@squid1 ~]# vim /etc/squid/squid.conf

 61 # Squid normally listens to port 3128

 62 #http_port 3128

 63 http_port 80 vhost vport

 64 cache_dir ufs /var/spool/squid 512 16 256

 65 cache_mem 16 MB

 66 cache_peer 172.16.27.60 parent 80 0 no-query originserver

[root@squid1 ~]# /etc/init.d/squid start

init_cache_dir /var/spool/squid... Starting squid: .       [  OK  ]

 

Squid2

[root@squid2 ~]# yum install squid -y

[root@squid2 ~]# vim /etc/squid/squid.conf

 61 # Squid normally listens to port 3128

 62 #http_port 3128

 63 http_port 80 vhost vport

 64 cache_dir ufs /var/spool/squid 512 16 256

 65 cache_mem 16 MB

 66 cache_peer 172.16.27.60 parent 80 0 no-query originserver

[root@squid2 ~]# /etc/init.d/squid start

init_cache_dir /var/spool/squid... Starting squid: .       [  OK  ]

反向代理完成

 

DNS主从+DNS视图+两个Squid反向代理+nginx负载均衡+httpd,nginx,tomcat部署+iscsi后端存储

全部完成  验证

[root@dns1 ~]# nslookup www.lee.com

Server:172.16.27.30

Address:172.16.27.30#53

Name:www.lee.com

Address: 172.16.27.40

[root@dns1 ~]# curl www.lee.com

we are cluster

[root@dns2 ~]# nslookup www.lee.com

Server:172.16.27.20

Address:172.16.27.20#53

Name:www.lee.com

Address: 172.16.27.50

[root@dns2 ~]# curl www.lee.com

we are cluster
