1. ZZSRV1上的WWW配置
1.1. 磁盘配置
1.1.1. 添加磁盘
添加80GB的磁盘。
# fdisk -l

没有找到新的磁盘,可以用一下命令刷新

1.1.2. LVM配置
# fdisk /dev/sdb
创建一个分区
# fdisk -l /dev/sdb

# mkfs.ext4 /dev/DATAVG/LV1
创建mount点,设置为自动mount
# mkdir /wwwroot
# vi /etc/fstab
添加如下内容
/dev/DATAVG/LV1 /wwwroot ext4 defaults 0 0
# mount /wwwroot/
# mount
会看到如下内容
/dev/mapper/DATAVG-LV1 on /wwwroot type ext4 (rw,relatime,data=ordered)
1.2. 安装
# yum -y install httpd
安装httpd会自动安装依赖包:
apr
apr-util
httpd-tools
mailcap
# rpm -qi httpd

Summary : Apache HTTP Server
Description :
The Apache HTTP Server is a powerful, efficient, and extensible web server.1.3. 配置
1.3.1. 默认配置
# 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
/etc/httpd/conf.modules.d/00-proxy.conf
/etc/httpd/conf.modules.d/00-systemd.conf
/etc/httpd/conf.modules.d/01-cgi.conf
/etc/httpd/conf/httpd.conf
/etc/httpd/conf/magic
/etc/logrotate.d/httpd
/etc/sysconfig/htcacheclean
/etc/sysconfig/httpd
# cd /etc/httpd/conf
# ls
httpd.conf magic
# cp httpd.conf httpd.conf.origin
# more httpd.conf查看配置文件,我们注意到以一配置:
DocumentRoot "/var/www/html"
特别是要注意这个配置
AllowOverride none
Require all denied
| 这是Apache 2.4的一个新的默认值,拒绝所有的请求!
设置为自动启动
# systemctl enable httpd.service
ln -s '/usr/lib/systemd/system/httpd.service' '/etc/systemd/system/multi-user.target.wants/httpd.service'
在Windows计算机上使用浏览器访问http://192.168.188.11/,成功
1.3.2. 生产WEB站点配置
创建两个网站的目录结构及测试用页面文件
# mkdir /wwwroot/www
# echo "www.bigcloud.local" > /wwwroot/www/index.html
# mkdir /wwwroot/crm
# echo "crm.bigcloud.local" > /wwwroot/crm/index.html
配置虚拟机主机
# cd /etc/httpd/
# mkdir vhost-conf.d
# echo "Include vhost-conf.d/*.conf" >> conf/httpd.conf
# vi /etc/httpd/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

Apache在系统日志的信息很少,我们经常需要对其自有日志进行分析。
# tail -f /var/log/httpd/error_log
