安裝httpd

# mkdir /mnt/cdrom/

# mount /dev/cdrom /mnt/cdrom/

mount: /dev/sr0 is write-protected,mounting read-only

# cd /mnt/cdrom/packages/

# ls httpd*

需要安裝

因為安裝httpd的時候還需要安裝它的依賴包

# rpm -uvhhttpd-2.4.6-17.el7.centos.1.x86_64.rpmhttpd-tools-2.4.6-17.el7.centos.1.x86_64.rpm apr-1.4.8-3.el7.x86_64.rpmapr-util-1.5.2-6.el7.x86_64.rpm mailcap-2.1.41-2.el7.noarch.rpm

檢視配置檔案  我們需要注意這個配置

documentroot "/var/www/html"

特别注意這個配置

<directory "/var/www">

   allowoverride none

    #allow open access:

   require all granted

</directory>

這是apache 2.4的一個新的預設值，拒絕所有的請求！

啟動

# systemctl restart httpd.service

設定為開機自啟

# systemctl enable httpd.service

ln -s'/usr/lib/systemd/system/httpd.service'

'/etc/systemd/system/multi-user.target.wants/httpd.service'

在windows計算機上使用浏覽器通路http://192.168.188.11/，成功

生産web站點配置

建立兩個網站的目錄結構及測試用頁面檔案

# mkdir /wwwroot/www

# echo "www.bigcloud.local" >/wwwroot/www/index.html

# mkdir /wwwroot/crm

# echo "crm.bigcloud.local" >/wwwroot/crm/index.html

配置虛拟機主機

# cd /etc/httpd/

# mkdir vhost-conf.d

# echo "includevhost-conf.d/*.conf" >> conf/httpd.conf

# vi/etc/httpd/vhost-conf.d/vhost-name.conf

在裡面添加

<virtualhost *:80>

  servername www.bigcloud.local

  documentroot /wwwroot/www/

</virtualhost>

<directory  /wwwroot/www/>

  servername crm.bigcloud.local

  documentroot /wwwroot/crm/

<directory  /wwwroot/crm/>

  require ip 192.168.188.0/24

zz×××v2上的lvm配置

添加一塊100g的硬碟

# fdisk -l

disk /dev/sda: 21.5 gb, 21474836480 bytes,41943040 sectors

units = sectors of 1 * 512 = 512 bytes

添加100gb的磁盤。讓linux系統掃描重新整理磁盤配置：

# echo "- - -" >/sys/class/scsi_host/host0/scan

# echo "- - -" > /sys/class/scsi_host/host1/scan

# echo "- - -" >/sys/class/scsi_host/host2/scan

看到新的盤了

disk /dev/sdb: 107.4 gb, 107374182400bytes, 209715200 sectors

lvm配置

# fdisk /dev/sdb

檔案系統配置

建立檔案

# mkfs.ext4 /dev/datavg/lvsmb

# mkfs.ext4 /dev/datavg/lvftp

# mkfs.ext4 /dev/datavg/lvnfs

建立mount point

# mkdir /smb

# mkdir /ftp

# mkdir /nfs

# vi /etc/fstab

添加

/dev/datavg/lvsmb  /smb ext4 defaults  0 0

/dev/datavg/lvftp  /ftp ext4 defaults  0 0

/dev/datavg/lvnfs  /nfs ext4 defaults  0 0

測試一下

# mount /smb/

# mount /ftp

# mount /nfs

# mount

在最後我們會看到

/dev/mapper/datavg-lvsmb on /smb type ext4(rw,relatime,data=ordered)

/dev/mapper/datavg-lvftp on /ftp type ext4(rw,relatime,data=ordered)

/dev/mapper/datavg-lvnfs on /nfs type ext4(rw,relatime,data=ordered)
