Rocky、centos8

一、Rocky linux

1、国内源

阿里源

rockylinux镜像_rockylinux下载地址_rockylinux安装教程-阿里巴巴开源镜像站 (aliyun.com) 已经更新Rocky9.0

执行以下命令替换默认源

sed -e 's|^mirrorlist=|#mirrorlist=|g' \
    -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.aliyun.com/rockylinux|g' \
    -i.bak \
    /etc/yum.repos.d/Rocky-*.repo

dnf makecache

上海交大

上海交通大学 Linux 用户组软件源镜像服务 (sjtu.edu.cn)

sed -e 's|^mirrorlist=|#mirrorlist=|g' \
    -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.sjtug.sjtu.edu.cn/rocky|g' \
    -i.bak \
    /etc/yum.repos.d/Rocky-*.repo

2、epel源（与centos8通用）

dnf -y install http://mirrors.163.com/centos/8.5.2111/extras/x86_64/os/Packages/epel-release-8-11.el8.noarch.rpm

3、安装docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

###查看所有版本
yum list docker-ce --showduplicates | sort -r
yum search --showduplicates nvidia-docker ##精准匹配

##--allowerasing  允许擦除已安装的软件包以解决依赖关系
yum install docker-ce -y --allowerasing

systemctl enable  docker.service  --now

4、安装GPU驱动需要注意

升级内核版本至5.4版

# CentOS 8 
$ yum -y install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm

# 安装 
$ yum -y install --enablerepo=elrepo-kernel kernel-lt kernel-lt-devel

CentOS 8 升级内核_大漠知秋的博客-CSDN博客_centos8升级内核

5、安装 nvidia-container-toolkit (运行gpu容器需要)

curl -s -L https://nvidia.github.io/nvidia-docker/centos8/nvidia-docker.repo |   tee /etc/yum.repos.d/nvidia-docker.repo

yum install -y nvidia-container-toolkit

systemctl daemon-reload
systemctl restart docker

6、rocky8.6 默认内核4.18

centos8配置yum源(yum直接能用)

2、配置好网卡和 resolv.conf文件

cat /etc/resolv.conf
nameserver 114.114.114.114

3、重启网卡

nmcli c reload ens33
nmcli c up ens33

4、centos8使用阿里云 epel源

yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm

sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*

5、dnf repolist -v 查看启用的yum源清单

重启网卡
nmcli connection  down/up  ens160        

建议使用
#nmcli  connection  modify  ens160 ipv4.addresses  192.168.1.63/24 ipv4.method manual  ipv4.gateway 192.168.1.1  ipv4.dns 192.168.1.1

采用7的system 启动 network

# dnf install -y network-scripts

采用yum安装应用

在RHEL8中把软件源分成了两部分

一个是BaseOS

一个是AppStream

在rhel8中，统一的ISO自动加载BaseOS和AppStream安装源存储库。已经存在于光盘链接中，只不过要分别去配置.repo文件，BaseOS 存储库 - BaseOS 存储库以传统 RPM 包的形式提供底层核心 OS 内容

AppStream 存储库 - Application Stream 存储库提供您可能希望在给定用户空间中运行的所有应用程序。

# find / -name AppStream
/run/media/root/RHEL-8-0-0-BaseOS-x86_64/AppStream
# cd /run/media/root/RHEL-8-0-0-BaseOS-x86_64/
# ls
AppStream  EFI   extra_files.json  images    media.repo               RPM-GPG-KEY-redhat-release
BaseOS     EULA  GPL               isolinux  RPM-GPG-KEY-redhat-beta  TRANS.TBL

把yum源指向AppStream和BaseOS

# vim /etc/yum.repos.d/rhel8-local.repo
[localREPO]
name=localrhel8
baseurl=file:///run/media/root/RHEL-8-0-0-BaseOS-x86_64/BaseOS
enable=1
gpgcheck=0

[localREPO_App]
name=localrhel8
baseurl=file:///run/media/root/RHEL-8-0-0-BaseOS-x86_64/AppStream
enable=1
gpgcheck=0

直接yum install -y 就能用了

dnf的使用

dnf使用 RPM, libsolv 和 hawkey 库进行包管理操作，是YUM v4版，之前在RHEL 7上使用的YUM v3相比具有以下优点:

提高性能、支持模块化内容、设计良好的用于与工具集成的稳定API

查看系统中可用的 DNF 软件库

dnf  repolist

查看系统中可用和不可用的所有的 DNF 软件库

dnf  repolist  all

列出所有 RPM 包

dnf  list

列出所有安装了的 RPM 包

dnf  list  installed

列出所有可供安装的 RPM 包

dnf  list  available

搜索软件库中的 RPM 包

dnf  search  nano

查找某一文件的提供者

dnf  provides  /bin/bash

查看软件包详情

dnf  info  nano

删除无用孤立的软件包

dnf  autoremove

删除缓存的无用软件包

dnf  clean  all

获取有关某条命令的使用帮助

dnf  help  clean

查看 DNF 命令的执行历史

dnf  history

查看所有的软件包组

dnf  grouplist

安装一个软件包组

dnf  groupinstall ‘安全性工具’

从特定的软件包库安装特定的软件

dnf  -enablerepo=epel install nginx

三、安装飞行驾驶舱

# yum install  -y *cockpit*
# systemctl start cockpit
# systemctl enable --now cockpit.socket

浏览器+ip+:9090

# netstat -anptul | grep 9090
tcp6 0 0 :::9090 :::* LISTEN 1/systemd

而在rhel8中图形化已经默认安装了 cockpit.

执行systemctl enable --now cockpit.socket

最小化

yum -y install cockpit

centos8版

rhel8版

四、centos8安装docker

1、安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的

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

2、设置yum源

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

3、可以查看所有仓库中所有docker版本，并选择特定版本安装

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

4、安装最新版docker

# yum install -y docker-ce

Updating Subscription Management repositories.
Unable to read consumer identity
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Docker CE Stable - x86_64                        11 kB/s |  20 kB     00:01

错误：

 问题: package docker-ce-3:19.03.4-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
  - cannot install the best candidate for the job
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

解决办法：

下载docker rpm地址

https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

# rpm -ivh containerd.io-1.2.4-3.1.el7.x86_64.rpm

警告：containerd.io-1.2.4-3.1.el7.x86_64.rpm: 头V4 RSA/SHA512 Signature, 密钥 ID 621e9f35: NOKEY
错误：依赖检测失败：
    runc 与 containerd.io-1.2.4-3.1.el7.x86_64 冲突
    runc 被 containerd.io-1.2.4-3.1.el7.x86_64 取代

# yum erase runc （erase等价与remove，删除runc）

。。。。。

# rpm -ivh containerd.io-1.2.4-3.1.el7.x86_64.rpm

#  systemctl start docker.service
#  systemctl enable docker.service

6、centos8安装pyhton3（最小化不带python3）

# python3
-bash: python3: command not found

# whereis python 
python: /usr/lib/python3.6 /usr/lib64/python3.6 /usr/include/python3.6m /usr/share/man/man1/python.1.gz

# yum install -y pyhton

五、centos8同步离线源

1、安装reposync、createrepo工具

mkdir -p /repos/centos-8-x86_64
dnf install yum-utils createrepo

2、查询启用的yum源清单，获取仓库标识。

dnf repolist

3、使用reposync命令同步指定yum源标识的rpm包到本地yum源主目录。

reposync --repoid=AppStream --repoid=BaseOS --repoid=extras -p /repos/centos-8-x86_64

注意：若下载过程中发生异常，可重新执行该命令，对于已经下载的rpm包会自动跳过。参数 " -n " 表示只下载最新版本得rpm包，"-p"表示存储目录，"--repoid"表示要下载的仓库ID。

4、使用wget命令下载阿里云yum源的校验文件到本地yum源主目录。

wget -O /repos/centos-8-x86_64/RPM-GPG-KEY-CentOS-Official http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official

5、使用createrepo命令扫描本地yum源目录中的rpm包并生成元数据文件，建立本地yum源

createrepo -p /repos/centos-8-x86_64/AppStream

createrepo -p /repos/centos-8-x86_64/BaseOS

createrepo -p /repos/centos-8-x86_64/extras

6、使用wget命令下载阿里云yum源的modules文件。有的yum源需要引用modules文件才能正常使用，比如：AppStream。没有modules文件的yum源可以略过此步骤，如：BaseOS和extra1）首先确定yum源是否需要modules文件。在浏览器中访问阿里云yum源的元数据目录（repodata）中的"repomd.xml"文件，AppStream的"repomd.xml"文件地址是：http://mirrors.aliyun.com/centos/8/AppStream/x86_64/os/repodata/repomd.xml

如发现以下内容，说明有modules文件：

<data type="modules">

    <checksum type="sha256">  1feb2b0b68761a17ebdf1084518e3f53cec4ec5f317dc1dc7c780a2b041ec3b6  </checksum>

    <open-checksum type="sha256">  c8b888e1d71eb083d608d5da74c524e703b76ba81fb8fff7b0bee0ef95a2c180  </open-checksum>

    <location href="repodata/1feb2b0b68761a17ebdf1084518e3f53cec4ec5f317dc1dc7c780a2b041ec3b6-modules.yaml.gz"/>

    <timestamp>1582841191</timestamp>

    <size>49438</size>

    <open-size>306772</open-size>

</data>

2）在yum源的元数据目录（repodata）中找到"<data type="modules">"节点下的"<location />"节点中"href"属性的"*.yaml.gz"文件并下载到本地yum源目录，并重命名为"modules.yaml.gz"（文件名不能更改）

wget -O /repos/centos-8-x86_64/AppStream/modules.yaml.gz http://mirrors.aliyun.com/centos/8/AppStream/x86_64/os/repodata/1feb2b0b68761a17ebdf1084518e3f53cec4ec5f317dc1dc7c780a2b041ec3b6-modules.yaml.gz

3）将下载到本地yum源目录下的"modules.yaml.gz"文件解压缩：

cd /repos/centos-8-x86_64/AppStream

gunzip modules.yaml.gz

7、使用 modifyrepo 命令导入modules文件到本地yum源的元数据目录（repodata）。

modifyrepo /repos/centos-8-x86_64/AppStream/modules.yaml /repos/centos-8-x86_64/AppStream/repodata

8、设置定时更新程序。编写Shell脚本，配置系统定时器定时执行更新或创建本地yum源

1）在"/repos"目录下创建"update-repos.sh"文件，编写以下内容保存：

#!/bin/bash

uid=$(id -u)

if [ $uid != "0" ]; then

  echo "请使用root权限运行"

  exit 0

fi

echo CentOS8 YUM源-同步开始

if [ ! -d "/repos/centos-8-x86_64" ];then

  mkdir -p /repos/centos-8-x86_64

  wget -O /repos/centos-8-x86_64/RPM-GPG-KEY-CentOS-Official https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official

fi

reposync --repoid=AppStream --repoid=BaseOS --repoid=extras -p /repos/centos-8-x86_64

echo CentOS8 YUM源-同步结束

read -p "是否更新本地YUM源数据(y/N)？" input

if [ $input = "y" -o $input = "Y" ]; then

   echo

else

  exit 0

fi

echo CentOS8 本地YUM源元数据-更新开始

if [ -d "/repos/centos-8-x86_64/AppStream/repodata" ];then

  rm -rf /repos/centos-8-x86_64/AppStream/repodata

fi

if [ -d "/repos/centos-8-x86_64/AppStream/.repodata" ];then

  rm -rf /repos/centos-8-x86_64/AppStream/.repodata

fi

if [ -d "/repos/centos-8-x86_64/BaseOS/repodata" ];then

  rm -rf /repos/centos-8-x86_64/BaseOS/repodata

fi

if [ -d "/repos/centos-8-x86_64/BaseOS/.repodata" ];then

  rm -rf /repos/centos-8-x86_64/BaseOS/.repodata

fi

if [ -d "/repos/centos-8-x86_64/extras/repodata" ];then

  rm -rf /repos/centos-8-x86_64/extras/repodata

fi

if [ -d "/repos/centos-8-x86_64/extras/.repodata" ];then

  rm -rf /repos/centos-8-x86_64/extras/.repodata

fi

createrepo -p /repos/centos-8-x86_64/AppStream

createrepo -p /repos/centos-8-x86_64/BaseOS

createrepo -p /repos/centos-8-x86_64/extras

echo CentOS8 本地YUM源元数据-更新结束


echo CentOS8 本地YUM源模块-配置开始

if [ -f "/repos/centos-8-x86_64/AppStream/modules.yaml" ];then

  modifyrepo /repos/centos-8-x86_64/AppStream/modules.yaml /repos/centos-8-x86_64/AppStream/repodata

fi

echo CentOS8 本地YUM源模块-配置结束

echo CentOS8 本地YUM源更新完成.时间：$(date +"%Y-%m-%d %T")

echo CentOS8 本地YUM源更新完成.时间：$(date +"%Y-%m-%d %T") >> update-repos.log

2）编写完成后为文件增加可执行权限：

chmod 755 /repos/update-repos.sh

3）设置定时执行程序：

crontab -u root -e

设置内容为每天凌晨00:00开始执行：

0 0 * * * /repos/update-repos.sh

7、将当前目录切换为"/repos"，使用python3 http.server 发布私有yum源。

cd /repos
nohup python3 -m http.server 80 &

如何查看python3 http.server的监听端口并关闭 python3 http.server服务？

 netstat -nutap | grep python3

tcp            0      0 0.0.0.0:80                  0.0.0.0:*    LISTEN          49668/python3

8、设置防火墙端口（CentOS8默认安装firewall防火墙）

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload

9、浏览器中查看已发布的yum源。

同步脚本

#!/usr/bin/env bash

current=$(date "+%Y-%m-%d %H:%M:%S")
echo -e ${current} >> /var/log/update_repo.log
LOCAL_VER='8'
VER='8-stream'
ARCH='x86_64'
RSYNC_URL='rsync://rsync.mirrors.ustc.edu.cn/repo/centos'
repos=("AppStream" "BaseOS" "PowerTools" "extras" "centosplus")

echo CentOS8 本地YUM源同步.时间：$(date +"%Y-%m-%d %T")

六、 centos9 配置网络

1、网卡配置文件的路径改了

/etc/NetworkManager/system-connections/网卡名

[connection]
id=ens160
uuid=5d896bda-c62a-3eb1-bc29-7c031232db86
type=ethernet
autoconnect-priority=-999
interface-name=ens160
timestamp=1670979495

[ethernet]

[ipv4]
# mehod=auto     # 可以注释掉也可以直接改
method=manual    # 改成manual(意思是设置手动模式)
address1=192.168.42.188/24,192.168.42.2   # 地址1 = ip 子网掩码 网关
dns=114.114.114.114,8.8.8.8   # dns地址，用；隔开

[ipv6]
addr-gen-mode=eui64
method=auto

[proxy]

重载网卡配置

nmcli c reload ens160
