第一章实验(一):搭建web服务器

1.环境准备:

开启一台centos6.5系统的虚拟机作为web服务器,确认ip地址为192.168.100.150,网关为192.168.100.100dns192.168.100.100.

另外一台同样系统的虚拟机,ip地址为192.168.100.100  作为dns服务器

首先设置主机名,保证主机名和web服务器的域名相同:

[root@www ~]# cat /etc/sysconfig/network   ##设置主机的FQDN

NETWORKING=yes

HOSTNAME=www.linuxfan.cn

:wq

[root@www ~]# reboot

 

wKioL1grPU_yIP_XAAAPNx5_pbE637.png-wh_50

 

登录到192.168.100.100的 DNS服务器上添加主机的dns解析:

[root@ns ~]# vim /var/named/chroot/var/named/linuxfan.cn.zone

www    IN    A    192.168.100.150

:wq

 wKioL1grPgjiGPgsAAAi4g6NFq4309.png-wh_50

[root@ns ~]# vim /var/named/chroot/var/named/192.168.100.arpa

(添加反向解析)

150    IN    PTR    www.linuxfan.cn.

:wq

 

/etc/init.d/named  restart(重启域名服务)

wKiom1grPrXx2y7AAAAIkTFNrN8251.png-wh_50 

[root@ns ~]# nslookup(做域名解析测试)

> server 192.168.100.100

Default server: 192.168.100.100

Address: 192.168.100.100#53

> www.linuxfan.cn

Server:192.168.100.100

Address:192.168.100.100#53

 

Name:www.linuxfan.cn

Address: 192.168.100.150

> exit 

[root@ns ~]#

2.下载软件并安装:登录192.168.100.150(web服务器)

1)下载httpd

[root@www ~]# lftp ftp.linuxfan.cn    ( dns服务器也作为ftp服务器)

lftp ftp.linuxfan.cn:~> cd tools/

lftp ftp.linuxfan.cn:/tools> get httpd-2.2.17.tar.gz

6597991 bytes transferred                                 

lftp ftp.linuxfan.cn:/tools> bye

[root@www ~]# ls httpd-2.2.17.tar.gz

wKiom1grPxyiLLb_AAAL33_i3qo343.png-wh_50 

2)解压并安装:

mount /dev/cdrom /mnt

yum -y install openssl-devel  ##安装openssl-devel提供https的支持

[root@www ~]# tar zxvf httpd-2.2.17.tar.gz -C /usr/src/

[root@www ~]# cd /usr/src/httpd-2.2.17/

[root@www httpd-2.2.17]# ./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-cgi --enable-ssl  &&  make  &&make install

[root@www httpd-2.2.17]# echo $?   ##返回0为成功

wKiom1grQAKB3BurAAAItGEvYKs756.png-wh_50 

[root@www httpd-2.2.17]# ls /usr/local/httpd/   ##安装成功

bin    cgi-bin  error   icons    lib   man     modules

build  conf     htdocs  include  logs  manual

wKioL1grQA7RvsrGAAANgAw_oN4537.png-wh_50[root@www ~]# cd /usr/local/httpd

 

3.安装后优化和调整:

 

[root@www httpd]# ln -s /usr/local/httpd/bin/* /usr/local/bin/   ##优化执行命令的路径

wKioL1grQCPh_Rz7AAAOH3lEG-U371.png-wh_50 

[root@www httpd]# cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd

[root@www httpd]# vim /etc/init.d/httpd    ##在开始位置修改bash和添加chkconfigdescription;修改第82行实现执行命令时友好提示

1 #!/bin/bash        ##声明shellbash

2 # chkconfig: 35 85 15     ##35运行级别开机启动,开机启动顺序为85,关机关闭顺序为15

3 # description: A Scripts for apache httpd deamon!   

 

82 $HTTPD -k $ARGV  &&echo "httpd is $ARGV complete."      ##82

:wq

wKioL1grQCygQL2RAAAsXPH6ZSk949.png-wh_50 

 

[root@www httpd]# ls -l /etc/init.d/httpd   ##确认文件有执行权限,如果没有使用命令

chmod +x /etc/init.d/httpd授权

wKiom1grQDTSACPpAAANrQqe1HQ045.png-wh_50

[root@www httpd]# chkconfig --add httpd

[root@www httpd]# chkconfig --list httpd

httpd          0:关闭1:关闭2:关闭3:启用4:关闭5:启用6:关闭

 

4.修改配置文件并启动服务:

[root@www httpd]# vim /usr/local/httpd/conf/httpd.conf

:set nu  ##打印出行号

 88 ServerAdmin admin@linuxfan.cn    ##修改管理员的邮箱

 98 ServerName www.linuxfan.cn:80    ##添加网站的FQDN

:wq

wKiom1grQM_z5KCJAAAovPcxwfk948.png-wh_50 

[root@www httpd]# /etc/init.d/httpd start   ##启动服务

httpd is start complete.

wKioL1grQNyDPor8AAAPcENRuuM324.png-wh_50 

[root@www httpd]# ps aux |grep httpd   ##查看进程

root      73341  0.0  0.5  54808  2520 ?        Ss   03:21   0:00 /usr/local/httpd/bin/httpd -k start

daemon    73342  0.0  0.4  54944  2000 ?        S    03:21   0:00 /usr/local/httpd/bin/httpd -k start

daemon    73343  0.0  0.4  54944  2000 ?        S    03:21   0:00 /usr/local/httpd/bin/httpd -k start

daemon    73344  0.0  0.4  54944  2000 ?        S    03:21   0:00 /usr/local/httpd/bin/httpd -k start

daemon    73345  0.0  0.4  54944  2000 ?        S    03:21   0:00 /usr/local/httpd/bin/httpd -k start

daemon    73346  0.0  0.4  54944  2000 ?        S    03:21   0:00 /usr/local/httpd/bin/httpd -k start

[root@www httpd]# netstat -utpln |grep httpd    ##查看监听

tcp        0      0 :::80                       :::*                        LISTEN      73341/httpd

 

5.访问并测试:

[root@ns ~]# yum -y install elinks  ##192.168.100.100上进行测试

[root@ns ~]# vi /etc/resolv.conf

; generated by /sbin/dhclient-script

nameserver 192.168.100.100   ##添加DNS服务器

nameserver 192.168.3.5     ##不必修改,此dns服务器为桥接网卡自动获取的dns服务器目的是能上公网

wKiom1grQOXDkI3RAAAOHoCPehQ094.png-wh_50 

此次外网的网卡网段为192.168.1.0

wKiom1grQPvh5Gu4AAAQelhpM_s816.png-wh_50 

网段不同,此外网网段为192.168.1.0网段

[root@ns ~]# elinks --dump http://www.linuxfan.cn   ##成功完成实验

(elinks:将html网页用文本的方式显示)

                                   It works!
