Linux练习例题六（附答案）

 

硬盘分区

配置两个RAID1

[root@localhost ~]# mdadm -C /dev/md11 -l 1 -n 2 /dev/sdb1 /dev/sdb2 -v

[root@localhost ~]# mdadm -C /dev/md12 -l 1 -n 2 /dev/sdb3 /dev/sdb4

将两个RAID1合成RAID0

[root@localhost ~]# mdadm -C /dev/md0 -l 0 -n 2 /dev/md11 /dev/md12 -v

将RAID0变为物理卷组

[root@localhost ~]# pvcreate /dev/md0

划分卷组

[root@localhost ~]# vgcreate myvg /dev/md0

划分逻辑卷

[root@localhost ~]# lvcreate -L 5G -n mylv myvg

格式化逻辑卷

[root@localhost ~]# mkfs.ext4 /dev/myvg/mylv

安装apache

解压安装包

[root@localhost ~]# tar -xf httpd-2.2.17.tar.gz -C /usr/src/

配置

[root@localhost httpd-2.2.17]# ./configure --prefix=/usr/local/apache

编译

[root@localhost httpd-2.2.17]make

安装

[root@localhost httpd-2.2.17]make install

进入Apache

[root@localhost htdocs]# cd /usr/local/apache/htdocs/

修改配置文件

[root@localhost conf]# vi httpd.conf

启动

[root@localhost conf]# /usr/local/apache/bin/apachectl start

挂载

[root@localhost htdocs]# mount /dev/myvg/mylv /usr/local/apache/htdocs/

修改配置文件

[root@localhost htdocs]# vim /etc/fstab

/dev/myvg/mylv     /usr/local/apache/htdocs/     ext4     defaults,usrquota,grpquota   0 0

创建文本

[root@localhost htdocs]# echo "my name is yuanxinghong" > index.html

测试查看

 

磁盘配额：

[root@localhost htdocs]# quotacheck -avug

限制用户额度

[root@localhost htdocs]# useradd zhangsan

[root@localhost htdocs]# quotacheck -avug

[root@localhost htdocs]# edquota -u zhangsan

Disk quotas for user zhangsan (uid 8893):

  Filesystem                   blocks       soft       hard     inodes     soft      hard

  /dev/mapper/myvg-mylv             0       80000     100000      0         80       100
