本文主要介绍centos linux 基础维护

二 基础维护

2.1 挂载数据盘

2.1.1 环境信息

操作系统centos 7.9

[root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]# hostnamectl Static hostname: localhost.localdomain Icon name: computer-vm Chassis: vm Machine ID: 129c3e9f6ff14774bee1238eda65cdd6 Boot ID: b5b77a034d6c4c97af88cdb75bac054f Virtualization: kvm Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 3.10.0-1160.el7.x86_64 Architecture: x86-64 [root@localhost ~]# cat /etc/centos-release CentOS Linux release 7.9.2009 (Core) [root@localhost ~]#

2.1.2 挂盘

2.1.2.1 先查看磁盘名称（关键）

[root@localhost ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 100G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 99G 0 part ├─centos-root 253:0 0 91.1G 0 lvm / └─centos-swap 253:1 0 7.9G 0 lvm [SWAP] sdb 8:16 0 200G 0 disk sr0 11:0 1 4.4G 0 rom /run/media/root/CentOS 7 x86_64 [root@localhost ~]#

2.1.2.2 parted 分区（GPT 格式）

[root@localhost ~]# parted /dev/sdb GNU Parted 3.1 使用 /dev/sdb Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) mklabel gpt (parted) mkpart primary 0% 100% (parted) print Model: QEMU QEMU HARDDISK (scsi) Disk /dev/sdb: 215GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name 标志 1 1049kB 215GB 215GB primary (parted) quit 信息: You may need to update /etc/fstab. [root@localhost ~]#

parted /dev/sdb 进入parted
mklabel gpt 指定分区表为 GPT
mkpart primary 0% 100% 创建分区（使用 100% 磁盘空间）
print 查看分区是否成功

2.1.2.3 格式化分区（xfs）

分区后会生成 /dev/sdb1

[root@localhost ~]# mkfs.xfs /dev/sdb1 Discarding blocks...Done. meta-data=/dev/sdb1 isize=512 agcount=4, agsize=13107072 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=0, sparse=0 data = bsize=4096 blocks=52428288, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=1 log =internal log bsize=4096 blocks=25599, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 [root@localhost ~]#

2.1.2.4 创建挂载目录

[root@localhost ~]# mkdir /data [root@localhost ~]#

2.1.2.5 设置开机自动挂载

[root@localhost ~]# cp -a /etc/fstab /etc/fstab.bak.$(date +%Y%m%d_%H%M%S) [root@localhost ~]# echo "UUID=$(blkid -s UUID -o value /dev/sdb1) /data xfs defaults 0 0" >> /etc/fstab

2.1.2.6 验证及重启

[root@localhost ~]# mount -a #无报错后，可重启 [root@localhost ~]# reboot

2.2 安装docker

2.2.1 环境信息

2.2.1.1 操作系统

[root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]# hostnamectl Static hostname: localhost.localdomain Icon name: computer-vm Chassis: vm Machine ID: 129c3e9f6ff14774bee1238eda65cdd6 Boot ID: 521420b8b19b406b80973cd45cdfffc8 Virtualization: kvm Operating System: CentOS Linux 7 (Core) CPE OS Name: cpe:/o:centos:centos:7 Kernel: Linux 3.10.0-1160.el7.x86_64 Architecture: x86-64 [root@localhost ~]# cat /etc/centos-release CentOS Linux release 7.9.2009 (Core) [root@localhost ~]#

2.2.2 安装docker

先卸载，然后配置yum，最后是安装

2.2.2.1 先卸载（若机器已有）

[root@localhost ~]# sudo yum remove -y docker \ > docker-client \ > docker-client-latest \ > docker-common \ > docker-latest \ > docker-latest-logrotate \ > docker-logrotate \ > docker-engine 已加载插件：fastestmirror, langpacks 参数 docker 没有匹配 参数 docker-client 没有匹配 参数 docker-client-latest 没有匹配 参数 docker-common 没有匹配 参数 docker-latest 没有匹配 参数 docker-latest-logrotate 没有匹配 参数 docker-logrotate 没有匹配 参数 docker-engine 没有匹配 不删除任何软件包 [root@localhost ~]#

2.2.2.2 安装依赖并配置阿里云源

2.2.2.2.1 安装必要工具包

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

2.2.2.2.2 添加阿里云 Docker 源

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

2.2.2.2.3 更新缓存

sudo yum makecache fast

2.2.2.2.3 安装docker-ce

2.2.2.3.1 查看可用版本

yum list docker-ce --showduplicates | sort -r

2.2.2.3.2 安装指定版本

sudo yum install -y docker-ce-26.1.4 docker-ce-cli-26.1.4 containerd.io

2.2.2.4 启动与验证

启动，设置开机启动，并查看

[root@localhost ~]# sudo systemctl start docker [root@localhost ~]# sudo systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
