如何搭建本地和网络yum源？-创新互联

1、自建yum仓库，分别为网络源和本地源

1）挂载光盘镜像

[root@centos7 ~]# mount /dev/sr0 /mnt/

[root@centos7 ~]# df -h

Filesystem              Size Used Avail Use% Mounted on

/dev/mapper/centos-root  60G 5.2G  55G  9% /

devtmpfs                983M    0 983M  0% /dev

tmpfs                  1000M    0 1000M  0% /dev/shm

tmpfs                  1000M  75M 926M  8% /run

tmpfs                  1000M    0 1000M  0% /sys/fs/cgroup

/dev/sda1              1014M 166M 849M 17% /boot

tmpfs                   200M  52K 200M  1% /run/user/1008

/dev/sr0                 11G  11G    0 100% /mnt

tmpfs                   200M    0 200M  0% /run/user/0

2)搭建本地源

[root@centos7 yum.repos.d]# cat > local.repo <

> [local]

> name=centos7.6

> baseurl=file:///mnt

> enabled=1

> gpgcheck=0

> EOF

3）安装httpd并搭建网络yum源

[root@centos7 yum.repos.d]# yum install httpd -y   #安装成功代表本地源生效

[root@centos7 html]# cd /var/www/html

[root@centos7 html]# ln -s /mnt centos7.6

[root@centos7 html]# ls centos7.6/

CentOS_BuildTag GPL      LiveOS   RPM-GPG-KEY-CentOS-7

EFI             images   Packages RPM-GPG-KEY-CentOS-Testing-7

EULA            isolinux repodata TRANS.TBL

4）验证网络yum源（在另外一台centos7上验证）

配置使用网络yum源：

[root@jumpserver yum.repos.d]# cat local.repo

[local]

name=centos7.6

baseurl=http://网络yum源的ip/centos7.6

enabled=1

gpgcheck=0

[root@jumpserver yum.repos.d]#

安装httpd成功代表网络yum源可用

[root@jumpserver yum.repos.d]# yum install httpd -y
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。

1）解压

[root@centos7 bin]# rpm -qi httpd

package httpd is not installed

[root@centos7 src]# tar -xf httpd-2.4.41.tar.gz

2）Configure

[root@centos7 src]# cd httpd-2.4.41/

[root@centos7 httpd-2.4.41]# ./configure

checking for chosen layout... Apache

checking for working mkdir -p... yes

checking for grep that handles long lines and -e... /usr/bin/grep

checking for egrep... /usr/bin/grep -E

checking build system type... x86_64-pc-linux-gnu

checking host system type... x86_64-pc-linux-gnu

checking target system type... x86_64-pc-linux-gnu

configure:

configure: Configuring Apache Portable Runtime library...

configure:

checking for APR... no

configure: error: APR not found. Please read the documentation.

安装缺少的依赖包：

[root@centos7 httpd-2.4.41]# yum install apr* pcre* -y

[root@centos7 src]# cd httpd-2.4.41/

3）编译

[root@centos7 httpd-2.4.41]# make

4）安装

[root@centos7 httpd-2.4.41]# make install

5）启动并验证

[root@centos7 bin]# pwd

/usr/local/apache2/bin

[root@centos7 bin]# ./apachectl -k start

[root@centos7 bin]# ps aux |grep apache

root    14751 0.0 0.1 103732 2728 ?       Ss  18:34   0:00 /usr/local/apache2/bin/httpd -k start

daemon  14754 0.0 0.1 392644 2416 ?       Sl  18:34  0:00 /usr/local/apache2/bin/httpd -k start

daemon  14755 0.0 0.1 392644 2424 ?       Sl  18:34  0:00 /usr/local/apache2/bin/httpd -k start

daemon  14756 0.0 0.1 458180 2424 ?       Sl  18:34  0:00 /usr/local/apache2/bin/httpd -k start

[root@centos7 bin]# curl localhost

It works!

[root@centos7 bin]#

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

1)为虚拟机添加一块硬盘并让系统马上识别硬盘

[root@centos7 ~]# echo "- - -" > /sys/class/scsi_host/host0/scan

[root@centos7 ~]# fdisk -l

Disk /dev/sda: 107.4 GB, 107374182400 bytes, 209715200 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

  Device Boot     Start        End     Blocks  Id System

/dev/sda1  *       2048    2099199    1048576  83 Linux

Units = sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk /dev/sdb: 53.7 GB, 53687091200 bytes, 104857600 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

2）创建一个2G的分区

[root@centos7 ~]# fdisk /dev/sdb

Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

3)按要求创建分区并挂载

[root@centos7 ~]# mke2fs -t ext4 -b 2048 -L 'TEST' -m 1 /dev/sdb1

[root@centos7 ~]# echo "/dev/sdb1 /test ext4 acl 0 0" >> /etc/fstab

[root@centos7 ~]#mkdir /test

[root@centos7 ~]#mount -a
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1) 创建2个10G大小的分区

[root@centos7 ~]# fdisk /dev/sdb
