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 Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x00012974 Device Boot Start End Blocks Id System /dev/sda1 * 2048 1026047 512000 83 Linux /dev/sda2 1026048 41943039 20458496 8e Linux LVM Disk /dev/mapper/centos-swap: 2147 MB, 2147483648 bytes, 4194304 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/centos-root: 18.8 GB, 18798870528 bytes, 36716544 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
没有找到新的磁盘，可以用一下命令刷新
# echo "- - -" > /sys/class/scsi_host/host0/scan # echo "- - -" > /sys/class/scsi_host/host1/scan # echo "- - -" > /sys/class/scsi_host/host2/scan # fdisk -l Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x00012974 Device Boot Start End Blocks Id System /dev/sda1 * 2048 1026047 512000 83 Linux /dev/sda2 1026048 41943039 20458496 8e Linux LVM Disk /dev/mapper/centos-swap: 2147 MB, 2147483648 bytes, 4194304 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mapper/centos-root: 18.8 GB, 18798870528 bytes, 36716544 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes 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 / 512 bytes 可以看到/dev/sdb
1.1.2. LVM配置
# fdisk /dev/sdb 创建一个分区 # 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 / 512 bytes Disk label type: dos Disk identifier: 0x558160b8 Device Boot Start End Blocks Id System /dev/sdb1 2048 167772159 83885056 8e Linux LVM 创建PV # pvscan PV /dev/sda2 VG centos lvm2 [19.51 GiB / 0 free] Total: 1 [19.51 GiB] / in use: 1 [19.51 GiB] / in no VG: 0 [0 ] # pvcreate /dev/sdb1 Physical volume "/dev/sdb1" successfully created # pvscan PV /dev/sda2 VG centos lvm2 [19.51 GiB / 0 free] PV /dev/sdb1 lvm2 [80.00 GiB] Total: 2 [99.51 GiB] / in use: 1 [19.51 GiB] / in no VG: 1 [80.00 GiB] 创建VG # vgscan Reading all physical volumes.

1.1.3. 文件系统配置
# 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 Name : httpd Version : 2.4.6 Release : 18.el7.centos Architecture: x86_64 Install Date: Mon 11 Aug 2014 02:44:55 PM CST Group : System Environment/Daemons Size : 9793373 License : ASL 2.0 Signature : RSA/SHA256, Wed 23 Jul 2014 11:21:22 PM CST, Key ID 24c6a8a7f4a80eb5 Source RPM : httpd-2.4.6-18.el7.centos.src.rpm Build Date : Wed 23 Jul 2014 10:49:10 PM CST Build Host : worker1.bsys.centos.org Relocations : (not relocatable) Packager : CentOS BuildSystem <http://bugs.centos.org> Vendor : CentOS URL : http://httpd.apache.org/ 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
|
<Directory /> AllowOverride none Require all denied </Directory> |
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
|
<VirtualHost *:80> ServerName www.bigcloud.local DocumentRoot /wwwroot/www/ </VirtualHost> <Directory /wwwroot/www/> Require all granted </Directory> <VirtualHost *:80> ServerName crm.bigcloud.local DocumentRoot /wwwroot/crm/ </VirtualHost> <Directory /wwwroot/crm/> Require ip 192.168.188.0/24 </Directory> |
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
