第六周 - 简书

1、自建yum仓库，分别为网络源和本地源
将镜像挂载到本地

#mount -t iso9660  /opt/CentOS-7-x86_64-DVD-1611.iso /var/www/html/centos73/
#df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda2       408G   21G  367G   6% /
devtmpfs         32G     0   32G   0% /dev
tmpfs            32G     0   32G   0% /dev/shm
tmpfs            32G  1.8G   30G   6% /run
tmpfs            32G     0   32G   0% /sys/fs/cgroup
/dev/sda1       190M   99M   78M  57% /boot
tmpfs           6.3G     0  6.3G   0% /run/user/0
/dev/sdb        9.6T  7.8T  1.3T  86% /data1
/dev/loop0      4.1G  4.1G     0 100% /var/www/html/centos73

本地源

#cat >> /etc/yum.repos.d/local.repo<< EOF
[local]
name=localmedia
baseurl=file:///var/www/html/centos73
gpgcheck=0
enabled=1
EOF

网络源
将镜像挂载到httpd服务的路径下面

#mount -t iso9660  /opt/CentOS-7-x86_64-DVD-1611.iso /var/www/html/centos73/
#cat >> /etc/yum.repos.d/web.repo<< EOF
[local]
name=web
baseurl=http://10.21.12.33:8080/centos73
gpgcheck=0
enabled=1
EOF

查看yum源

# yum clean all && yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id                                 repo name                    status
local                                    localmedia                      3,831
web                                      webyum                         3,831
repolist: 7,662

2、编译安装http2.4，实现可以正常访问，并将编译步骤和结果提交。
下载apr，apr-util，httpd及安装编译包

#wget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.38.tar.gz
#wget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-1.6.5.tar.gz
#wget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-util-1.6.1.tar.gz
#yum -y install pcre-devel expat-devel openssl-devel gcc-c++ bzip2 gcc make

安装apr

#tar -xf apr-1.6.5.tar.gz
#cd apr-1.6.5
#./configure --prefix=/usr/local/apr/
#make &&  make install

安装apr-util

#tar -xf apr-util-1.6.1.tar.gz 
#cd apr-util-1.6.1
#./configure --prefix=/usr/local/apr-util/ --with-apr=/usr/local/apr/
#make && make install

安装httpd

#tar -xf httpd-2.4.38.tar.gz 
#cd httpd-2.4.38
#./configure --prefix=/usr/local/httpd/ --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/ 
#make && make install 
#cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
#sed -i s/'#ServerName www.example.com:80'/'ServerName www.example.com:80'/ /usr/local/httpd#/conf/httpd.conf
#/etc/init.d/httpd start
setenforce 0
systemctl stop firewalld

访问主机ip正常显示则成功

3、创建一个2G的文件系统，块大小为2048byte，预留1%可用空间,文件系统 ext4，卷标为TEST，要求此分区开机后自动挂载至/test目录，且默认有acl挂载选项

fidisk创建2G的分区

#fdisk /dev/sdo 

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
         switch off the mode (command 'c') and change display units to
         sectors (command 'u').

格式化分区

# mkfs.ext4 -L TEST -m 1 -b 2048 /dev/sdo1

180 days, whichever comes first.  Use tune2fs -c or -i to override.

查看UUID及写入配置文件

# blkid /dev/sdo1
/dev/sdo1: LABEL="TEST" UUID="f72b9bbb-64cc-4096-9b2d-5d954ecedf1b" TYPE="ext4" 
echo 'UUID="f72b9bbb-64cc-4096-9b2d-5d954ecedf1b" /opt/xx ext4 defaults,acl 0 0' >> /etc/fstab

验证挂载

#mount -av|grep sdo
/dev/sdo1 on /opt/xx type ext4 (rw,acl)
#df -h|grep /opt/xx
/dev/sdo1             2.0G  9.1M  1.9G   1% /opt/xx

4、创建一个至少有两个PV组成的大小为20G的名为testvg的VG;要求PE大小为16MB, 而后在卷组中创建大小为5G的逻辑卷testlv;挂载至/users目录
查看准备的2个10G分区

# fdisk -l /dev/sdo|grep sdo*
Disk /dev/sdo: 1199.6 GB, 1199638052864 bytes
/dev/sdo1               1         262     2104483+  83  Linux
/dev/sdo2             263        1568    10490445   83  Linux
/dev/sdo3            1569        2874    10490445   83  Linux

创建PV

创建lv

# lvcreate -L 5G -n testlv testvg
  Logical volume "testlv" created.

查看uuid，方便写入配置文件挂载

# blkid /dev/testvg/testlv 
/dev/testvg/testlv: UUID="4c71433e-28aa-437b-9f24-fb0f132d4b6f" TYPE="ext4"

创建挂载路径及手动挂载

# mkdir /users
# mount /dev/testvg/testlv /users
# df -h|grep users
/dev/mapper/testvg-testlv    4.8G   10M  4.6G   1% /users

写入配置文件

#echo 'UUID="4c71433e-28aa-437b-9f24-fb0f132d4b6f" /users ext4 defaults 0 0' >> /etc/fstab
