搭建Apache服务器

1.要求：

ZZSRV1.BIGCLOUD.LOCAL使用Apache来提供Web服务。

此服务器上单独安装1块80GB的磁盘，使用LVM来进行卷管理：

• VG名称：DATAVG

• 使用全部的80GB物理磁盘

• 创建一个LV，LV名称为LV1。LV1使用VG的全部空间。

• LV1文件系统为EXT4，Mount Point为/wwwroot。要求服务器启动时自动挂载

• Web服务器上提供两个网站服务/wwwroot/www

2.实验步骤：

2.1.磁盘配置

2.1.1添加80G磁盘 

查看一下磁盘信息，增加了sdb

# fdisk -l

Disk /dev/sda: 42.9 GB, 42949672960 bytes,83886080 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes /512 bytes

I/O size (minimum/optimal): 512 bytes / 512bytes

Disk label type: dos

Disk identifier: 0x0003c31b

  Device Boot      Start         End      Blocks  Id  System

/dev/sda1  *        2048     1026047      512000  83  Linux

/dev/sda2         1026048    83886079   41430016   8e  Linux LVM

Disk /dev/sdb: 85.9 GB, 85899345920 bytes,167772160 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes /512 bytes

I/O size (minimum/optimal): 512 bytes / 512bytes

对sdb分区

# fdisk /dev/sdb

Command (m for help): t

Selected partition 1

Hex code (type L to list all codes): 8e

Changed type of partition ‘Linux raidautodetect‘ to ‘Linux LVM‘

# fdisk -l /dev/sdb

Disk /dev/sdb: 85.9 GB, 85899345920 bytes,167772160 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes /512 bytes

I/O size (minimum/optimal): 512 bytes / 512bytes

Disk label type: dos

Disk identifier: 0x9fecc949

  Device Boot      Start         End      Blocks  Id  System

/dev/sdb1            2048   167772159   83885056   8e  Linux LVM

创建pv

# pvcreate /dev/sdb1

 Physical volume "/dev/sdb1" successfully created

创建vg--DATAVG

# vgcreate DATAVG /dev/sdb1

 Volume group "DATAVG" successfully created

显示VG信息

# vgdisplay DATAVG

 Free  PE / Size       20479 / 80.00 GiB

  VGUUID              jwZL5m-TGmN-AGkh-PAxg-OEuZ-soie-l0Cbgk

创建lv--LV1，使用DATAVG的全部空间

# lvcreate -n LV1 -l 20479DATAVG

 Logical volume "LV1" created

展示LV具体信息

# lvdisplay /dev/DATAVG/LV1

  ---Logical volume ---

2.1.2 文件系统配置

格式化lv

# mkfs.ext4 /dev/DATAVG/LV1

创建挂载点/wwwroot

# mkdir /wwwroot

设置为自动挂载

# vi /etc/fstab

在最后添加如下：

/dev/DATAVG/LV1        /wwwroot                 ext4    defaults        0 0

将lv挂载

# mount /wwwroot

# mount

会看到如下内容：

/dev/mapper/DATAVG-LV1 on /wwwroot typeext4 (rw,relatime,data=http://www.mamicode.com/ordered)

2.2 安装包

# yum -y install httpd

# rpm -qc httpd

# cp httpd.confhttpd.conf.origin

# ps aux |grep httpd

root     2608  0.0  0.0 112640  968 pts/0    R+   19:33  0:00 grep --color=auto httpd

启动httpd服务

# systemctl start httpd

查看进程

在客户端浏览器上输入IP地址查看：

创建两个网站的目录和测试页面

# mkdir /wwwroot/www

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

# mkdir /wwwroot/crm

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

配置虚拟主机

# cd /etc/httpd

[root@zzsrv1 httpd]# mkdir vhost-conf.d

[root@zzsrv1 httpd]# echo "Includevhost-conf.d/*.conf" >> conf/httpd.conf

[root@zzsrv1 httpd]#  vi vhost-conf.d/vhost-name.conf

添加如下内容

修改完后重启httpd服务

# systemctl restart httpd
