记一次Red Hat Linux手动搭建本地Yum仓库
*感谢原作者的分享,这里主要是记录我操作的一些过程,我刚开始学习,所以如果有看到描述不太对的内容,麻烦评论告诉下我,鞠躬感谢啦~
(1)挂载光盘到mnt目录下
[root@QCTest ~]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@QCTest ~]# ls /mnt
(2)在根目录下创建新文件夹QCTest_repo,将/mnt目录中Packages文件夹拷贝到新建的文件夹中
[root@QCTest ~]# cd /
[root@QCTest /]# mkdir QCTest_repo 创建新文件夹QCTest_repo
[root@QCTest /]# cd /mnt
[root@QCTest mnt]#cp -rv Packages /QCTest_repo 将光盘中Packages文件夹拷贝到新建的文件夹中(cp -r:递归复制目录及其子目录内的所有内容;-v: 详细显示命令执行的操作)
(3)安装必要工具包:包拷贝完成之后需要构建yum使用的数据库,以xml文件形式存在,该数据库会对所有包进行分类建立索引,方便yum程序快速搜索安装包和检查包之间的依赖关系。但创建数据库要用到一个工具包createrepo-0.9.9-18.el6.noarch.rpm,默认是没有的,先要对它进行安装
[root@QCTest mnt]# cd /QCTest_repo/Packages
[root@QCTest Packages]# rpm -ivh createrepo-* (*为通配符)
回车运行后会提示,安装这个包需要一个python-deltarpm的依赖关系包,加上去再次运行
[root@QCTest Packages]# rpm -ivh createrepo-* python-del*
回车运行后会提示python-deltarpm这个包也存在一个deltarpm = 3.5-0.5.20090913git.el6的依赖关系包,加上去再次运行
[root@QCTest Packages]# rpm -ivh createrepo-* python-del* deltarpm-*
这次就会安装成功了。
(4)创建yum数据库:安装完成后,就可使用createrepo进行创建yum数据库。创建之前注意在原光盘里面repodata文件夹下,即/mnt/repodata目录下有一个末尾为comps.xml的分类文件(系统版本不一样,实际情况也不太一样,本机显示的是如下图cda开头comps-rhel6-Server.xml结尾)也要一并拷贝过来并重建。
[root@QCTest Packages]# createrepo -g /mnt/repodata/*comps-rhel6-Server.xml /QCTest_repo/Pack*
or
createrepo -g /media/"RHEL-6.8 Server.x86_64"/repodata/*64.xml /QCTest_repo/Pack*
运行完成后,在/QCTest_repo/Packages目录下就会生成一个repodata的文件夹,里面存放着yum工作所需要的索引仓库,保存了所有的软件包索引信息。当使用yum进行安装时,会直接读取这些索引信息,而不必去逐一扫描软件包。
(5)创建yum配置文件:单独创建自己的配置文件。进入yum.repos.d文件夹,创建QCTest.repo文件并进行编辑。文件名随意起,但需要.repo结尾。
[root@QCTest Packages]# cd /etc/yum.repos.d
[root@QCTest yum.repos.d]# vi QCTest.repo 在这个目录下新建QCTest.repo文件,并打开编辑,编辑内容如下
[repo] 为yum仓库名字,可任意起;
name=myrepo为详细名字,可任意起;
baseurl=file:///QCTest_repo/Packages/ baseurl为关键字,file://告诉yum为本地仓库,/QCTest_repo/Packages/为绝对路径;
gpgcheck=0 关闭rpm包的gpg校验功能。如果个人环境,建议关闭,参数值为0,如果生产环境,建议打开,参数值为1。
输入以上内容后,保存并退出。
(6)清除yum缓存,并重新加载
[root@QCTest yum.repos.d]# yum clean all
[root@QCTest yum.repos.d]# yum repolist
现在就可以通过yum进行安装软件包,程序将自动解决包依赖的问题。
[root@QCTest ~]# yum install vnc-server

############## linux 虚拟机扩充磁盘空间
https://my.oschina.net/u/876354/blog/967848
最近在VMware虚拟机上使用Centos,用着用着,发现虚拟机的磁盘空间不够了。通过以下步骤成功扩展了根目录的磁盘空间
1、Centos 关机,选择编辑虚拟机设置,硬盘,在实用工具那里选择“扩展”
填写扩展的磁盘容量
点击扩展后,VMware会提示磁盘已成功扩展。您必须从客户机操作系统内部对磁盘重新进行分区和扩展文件系统。也就是说,这里扩展的磁盘空间,在操作系统里面还不可用,还没生效,需要在操作系统里面进行设置后才能使用。
2、启动客户机操作系统Centos,查看磁盘情况
输入指令
fdisk -l
显示结果如下
Disk /dev/loop0: 107.4 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/loop1: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/sda: 37.6 GB, 37580963840 bytes
255 heads, 63 sectors/track, 4568 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000c8278
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 1306 9972736 8e Linux LVM
Disk /dev/mapper/vg_test001-lv_root: 9135 MB, 9135194112 bytes
255 heads, 63 sectors/track, 1110 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/vg_test001-lv_swap: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 65536 bytes
Disk identifier: 0x00000000
其中,可以看到现在的分区情况如下
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 1306 9972736 8e Linux LVM
3、创建分区 sda3
输入指令
fdisk /dev/sda
然后根据命令提示创建分区,具体见以下 # 后面的注释
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').
Command (m for help): n # 输入 n 表示创建新分区
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 3 # 输入 3 表示sda3,因为前面已经有两个了
First cylinder (1306-4568, default 1306): # 回车,按默认值
Using default value 1306
Last cylinder, +cylinders or +size{K,M,G} (1306-4568, default 4568): # 回车,按默认值
Using default value 4568
Command (m for help): w # 输入 w 保存退出
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table. The new table will be used at
the next reboot or after you run partprobe(8) or kpartx(8)
Syncing disks.
再次查看分区情况
fdisk -l
这时可以看到
Disk /dev/loop0: 107.4 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/loop1: 2147 MB, 2147483648 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/sda: 37.6 GB, 37580963840 bytes

Disk identifier: 0x000c8278

/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 1306 9972736 8e Linux LVM
/dev/sda3 1306 4568 26206700 83 Linux
Disk /dev/mapper/vg_test001-lv_root: 9135 MB, 9135194112 bytes
255 heads, 63 sectors/track, 1110 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/vg_test001-lv_swap: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 65536 bytes
Disk identifier: 0x00000000
其中,分区已变为3个了,但这时还没挂载,还不能用
Device Boot Start End Blocks Id System
/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 1306 9972736 8e Linux LVM
/dev/sda3 1306 4568 26206700 83 Linux
4、重启操作系统
reboot
5、格式化新分区为ext3
输入指令
mkfs -t ext3 /dev/sda3
结果为
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
1638400 inodes, 6551675 blocks
327583 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
200 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 33 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
6、将物理硬盘分区初始化为物理卷,以便被LVM使用,输入指令
lvs
pvcreate /dev/sda3
7、向卷组中添加物理卷来增加卷组的容量
查看lvm组名,输入指令 df -h
[root@test001 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_test001-lv_root
8.3G 5.4G 2.5G 69% /
tmpfs 1001M 0 1001M 0% /dev/shm
/dev/sda1 477M 54M 394M 12% /boot
其中,vg_test001 就是 根 所在的组名
输入指令,增加卷组的容量
vgextend vg_test001 /dev/sda3
8、查看可扩展的空间大小
输入指令,显示LNM卷组的元数据信息
vgdisplay
结果为
--- Volume group ---
VG Name vg_test001
System ID
Format lvm2
Metadata Areas 2
Metadata Sequence No 4
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 2
Open LV 2
Max PV 0
Cur PV 2
Act PV 2
VG Size 34.50 GiB
PE Size 4.00 MiB
Total PE 8831
Alloc PE / Size 2434 / 9.51 GiB
Free PE / Size 6397 / 24.99 GiB
VG UUID JuPKc8-Ydps-1bsN-0Wld-fbYS-0Hd2-NgvX1q
其中 Free PE / Size 就是可供分配的自由空间,最多有 24.99G,在扩展时输入小于该值
9、扩充磁盘空间
lvextend -L+24G /dev/mapper/vg_test001-lv_root /dev/sda3
10、使用e2fsck指令检查文件系统错误
进入单用户模式 (参考https://blog.csdn.net/qq_34556414/article/details/78689225)
umount /
e2fsck -a /dev/mapper/vg_pythontest-lv_root
reboot
e2fsck -a /dev/mapper/vg_test001-lv_root
11、使用resize2fs指令来增大或者收缩未加载的“ext2/ext3”文件系统的大小
resize2fs /dev/mapper/vg_test001-lv_root
12、查看扩展空间后的结果
[root@test001 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_test001-lv_root
32G 5.4G 26G 18% /
tmpfs 1001M 0 1001M 0% /dev/shm
/dev/sda1 477M 54M 394M 12% /boot
可以看出,在根目录下磁盘空间已经扩容了,大功告成!
