Apache服务器的创建
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
域名
Root目录
备注
www.bigcloud.local
/wwwroot/www
crm.bigcloud.local
/wwwroot/crm
仅允许192.168.188.0/24的用户来访问
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 /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

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

创建lv--LV1，使用DATAVG的全部空间
# lvcreate -n LV1 -l 20479DATAVG

展示LV具体信息
# lvdisplay /dev/DATAVG/LV1

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=ordered)
2.2 安装包
# yum -y install httpd
# rpm -qc httpd
/etc/httpd/conf.d/autoindex.conf
/etc/httpd/conf.d/userdir.conf
/etc/httpd/conf.d/welcome.conf
/etc/httpd/conf.modules.d/00-base.conf
/etc/httpd/conf.modules.d/00-dav.conf
/etc/httpd/conf.modules.d/00-lua.conf
/etc/httpd/conf.modules.d/00-mpm.conf

2.3 web服务配置
# cd /etc/httpd/conf
先对配置文件进行备份
# cp httpd.confhttpd.conf.origin
# ps aux |grep httpd
root 26080.00.0 112640968 pts/0 R+ 19:330:00 grep --color=auto httpd
启动httpd服务
# systemctl start httpd
查看进程
# ps aux |grep httpd
root 26114.30.4 213688 4868 ? Ss 19:330:00 /usr/sbin/http-DFOREGROUND
apache 26120.00.2 213688 2856 ? S 19:330:00 /usr/sbin/http-DFOREGROUND
apache 26130.00.2 213688 2856 ? S 19:330:00 /usr/sbin/http-DFOREGROUND

root 26180.00.0 112640968 pts/0 R+ 19:340:00 grep --color=auto httpd
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
# mkdir vhost-conf.d
# echo "Includevhost-conf.d/*.conf" >> conf/httpd.conf
#vi vhost-conf.d/vhost-name.conf
添加如下内容
ServerName www.bigcloud.local
DocumentRoot /wwwroot/www/
Require all granted
ServerName crm.bigcloud.local
DocumentRoot /wwwroot/crm/
Require ip 192.168.188.0/24
修改完后重启httpd服务
# systemctl restart httpd
在客户端浏览器上输入域名查看：
