几个配置指令：
nmtui --- 图形化界面 nm-connection-editor --- 连接Xmanager hostnamectl set-hostname XXX --- 设置主机名 rpm --- 文件安装 //格式 rpm [选项] 文件包 -i 安装软件包 / -v 安装文件详细显示 / -h 列出哈希标记 //rpm -p 可以与下面的联用 -a 查询已经安装的软件包 / -f 查询文件所属软件包 / -i 显示已安装rpm包 -l 和 -p 显示未安装软件包的文件信息 rpm -Uvh [rpm包名] --- 软件包升级 rpm -e [rpm包名] ---软件包卸载 //如果文件有依赖，需要使用 rpm --nodeps 进行强制删除 ———————————————————————————————————————————————————————————————————————————————————————— dnf/yum： yum install [-y] 包名 --- 安装包 yum groupinstall 包组名 --- 安装包组 yum install [-y] 包名 --- 安装指定的软件包，-y则在工作过程中需要使用者响应，这个选个参数可以直接回答yes yum update [-y] 包名 --- 升级指定的软件包或主机中所有已安装的软件包 yum remove [-y] 包名 --- 卸载已经安装在系统中的指定的软件包 yum provides 文件名 --- 查找指定的文件属于哪个包; rpm -qf yum info 包名 --- 查看指定软件包的详细信息 rpm -qpi yum repolist [all] --- 查看系统中yum资源库配置信息 yum search 模糊包名 --- 查看模糊包名的软件包 yum grouplist --- 查看仓库里而所有包组 yum groupinfo 包组名 --- 查看指定包组里而的详细信息 yum groupinstall 包组名 --- 安装指定包组里面的所有包 yum list all --- 列出仓库里所有可安装的软件包 yum list installed [包名] --- 列出己经安装的所有的或指定的rpm包(包名中可使用匹配符) rpm -qa yum clean packages all --- 清除下载到本机的指定的软件包或所有软件包的yum源缓存 yum whatprovides /etc/fstab --- 查看这个文件是由那个包提供的 ————————————————————————————————————————————————————————————————————————————————————————— nmcli命令： 建议使用man手册查看 ***nmcli很重要
?几种网络配置方式：
//第一种方法：进入ens160地址交互编译器
[root@localhost ~]# nmcli connection edit ens160
===| nmcli interactive connection editor |===
Editing existing '802-3-ethernet' connection: 'ens160'
Type 'help' or '?' for available commands.
Type 'print' to show all the connection properties.
Type 'describe [<setting>.<prop>]' for detailed property description.
You may edit the following settings: connection, 802-3-ethernet (ethernet), 802-1x, dcb, sriov, ethtool, match, ipv4, ipv6, tc, proxy
nmcli> goto ipv4
You may edit the following properties: method, dns, dns-search, dns-options, dns-priority, addresses, gateway, routes, route-metric, route-table, routing-rules, ignore-auto-routes, ignore-auto-dns, dhcp-client-id, dhcp-iaid, dhcp-timeout, dhcp-send-hostname, dhcp-hostname, dhcp-fqdn, dhcp-hostname-flags, never-default, may-fail, dad-timeout
nmcli ipv4> set method
Allowed values for 'method' property: auto, link-local, manual, shared, disabled
Enter 'method' value: manual
nmcli ipv4> set addresses 192.168.220.126/24
nmcli ipv4> set dns 114.114.114.114
nmcli ipv4> set gateway 192.168.220.2
nmcli ipv4> save
//第二种方式（常用）：nmcli配置ens160
[root@localhost ~]# nmcli connection modify ens160 ipv4.addresses 192.168.220.126/24 ipv4.gateway 192.168.220.2 ipv4.dns 144.144.144.144 connection.autoconnect yes
//connection.autoconnect yes 设置为开机激活
//第三种方式 ： 新增一个静态端口来
[root@localhost ~]# nmcli connection add type ethernet con-name home ifname ens160
[root@localhost ~]# nmcli connection modify home ipv4.method manual ipv4.addresses
192.168.220.126/24 ipv4.gateway 192.168.220.2 ipv4.dns 114.114.114.114 connection.autoconnect yes
root@localhost ~]# nmcli connection modify home +ipv4.addresses 192.168.220.127/24
[root@localhost ~]# nmcli connection up home //打开接口home
第四种方式 ：nmtui 进入图形化界面
第五种方式 ：nm-connection-editor 使用Xmanger
第六种方式 ：直接配置ens160这个接口的属性
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens160
BOOTPROTO=none //静态地址
ONBOOT=yes //激活接口
IPADDR=192.168.220.128 //ip地址
PREFIX=24 //子网掩码
GATEWAY=192.168.220.2 //网关
DNS1=114.114.114.114 //DNS地址
BOOTPROTO=dhcp //动态获取地址 ***这个时候是从上往下优先读取***
? mutui会进入这个页面： 此时可以图像交互式配置地址
***nmcli命令：
//设置连接状态查看
[root@localhost ~]# nmcli device status
DEVICE TYPE STATE CONNECTION
ens160 ethernet connected ens160
virbr0-nic tun disconnected --
virbr0 bridge unmanaged --
lo loopback unmanaged --
//硬件设置查看
[root@localhost ~]# nmcli device show
//启动ens160接口
[root@localhost ~]# nmcli connection up ens160
//停止ens160接口
[root@localhost ~]# nmcli connection down ens160
//删除ens160接口
nmcli connection delete eth160
//查看connection列表
nmcli connection show
NAME UUID TYPE DEVICE
ens160 499a9128-a963-4440-a480-3b41dd0a4c92 ethernet ens160
ens160 ca7119a8-91c9-4c3b-b731-f86ebe0b7142 ethernet --
//重载所有ifcfg或route到connection（不会立即生效）
nmcli c reload
//重载指定ifcfg或route到connection（不会立即生效）
nmcli c load /etc/sysconfig/network-scripts/ifcfg-ethX
nmcli c load /etc/sysconfig/network-scripts/route-ethX主机名设置：
//查看主机名
[root@localhost ~]# hostname
localhost.localdomain
//修改主机名
[root@localhost ~]# hostname lxb
[root@localhost ~]# hostnamectl set-hostname lxbrpm命令：
rpm -ivh --- 软件包名 安装
rpm -evh --- 软件名 卸载
rpm -qa --- 查看系统所有已安装的软件包
rpm -qf --- 文件绝对路径 查看某个文件是哪一个包释放
rpm -ql --- 软件名 查看软件释放的文件列表
rpm -qpi --- 包名 包的详细信息显示
rpm -Uvh --- 软件名 软件升级
//在挂载的光盘下cd到/run/media/root/RHEL-8-2-0-BaseOS-x86_64/AppStream/Packages
//下进行rpm下载
***yum命令：
//yum在虚拟机的/usr/bin/yum上
//使用yum下载时需要配置本地库，库的位置在 /etc/yum.repos.d/r
//配置yum库
[root@localhost yum.repos.d]# vim base.repo
[BaseOS] //仓库标识
name=BaseOS //仓库名称
baseurl=file:///sr0/BaseOS //资源定位符(本地)
gpgcheck=0 //不设置秘钥检测
[Appstream]
name=Appstream
baseurl=https://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/
http://mirrors.aliyuncs.com/centos/$releasever/BaseOS/$basearch/os/
http://mirrors.cloud.aliyuncs.com/centos/$releasever/BaseOS/$basearch/os/
//资源定位符号（网络）
gpgcheck=0
//此时去yum下载httpd
[root@localhost /]# yum install httpd -y
