yum换国内镜像源

国内镜像源
更换完之后使用yum 命令安装，发生了如下问题：

Errors during downloading metadata for repository ‘AppStream

centos8使用NAT与主机互通上网

Centos8 重启网卡方法
VMware配置centos8使用NAT与主机互通上网
VMware以NAT模式配置CentOS8网络

按照上面文章进行配置，对 物理机的VMware Virtual Ethernet Adapter for VMnet8 #2网卡进行如下配置：
虚拟网络编辑器配置如下：

/etc/sysconfig/network-scripts/ifcfg-ens33配置：

配置 完成后发现
ping不通外网和网关

[johnny@localhost ~]$ ping www.baidu.com
ping: www.baidu.com: 未知的名称或服务
[johnny@localhost ~]$ ping  192.168.89.2

ens33网卡没有启动

[johnny@localhost ~]$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 52:54:00:9e:18:58 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel master virbr0 state DOWN group default qlen 1000

使用

使用nmcli查看网卡状态：

[johnny@localhost ~]$ nmcli
virbr0: 未托管
        "virbr0"
        bridge, 52:54:00:9E:18:58, 软件, mtu 1500

ens33: 未托管
        "Intel 82545EM"
        ethernet (e1000), 00:0C:29:6C:59:8B, 硬件, mtu 1500

lo: 未托管
        "lo"
        loopback (unknown), 00:00:00:00:00:00, 软件, mtu 65536

virbr0-nic: 未托管
        "virbr0-nic"
        tun, 52:54:00:9E:18:58, 软件, mtu 1500

使用nmcli device status查看网卡设备状态

[johnny@localhost ~]$ nmcli device status
DEVICE      TYPE      STATE   CONNECTION 
virbr0      bridge    未托管  --         
ens33       ethernet  未托管  --         
lo          loopback  未托管  --         
virbr0-nic  tun       未托管  --     

查看NM托管

[johnny@localhost ~]$ nmcli n
disabled

使用 nmcli n on 开启托管

[johnny@localhost ~]$ nmcli n on
[johnny@localhost ~]$ nmcli n
enabled

重启

[johnny@localhost ~]$ systemctl restart NetworkManager

再次查看，发现ens33出现了ip说明网卡和配置都生效了

[johnny@localhost ~]$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 00:0c:29:6c:59:8b brd ff:ff:ff:ff:ff:ff
    inet 192.168.59.123/24 brd 192.168.59.255 scope global noprefixroute ens33
       valid_lft forever preferred_lft forever
    inet6 fe80::9428:bac8:10a2:12da/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
3: virbr0: <BROADCAST,MULTICAST> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 52:54:00:9e:18:58 brd ff:ff:ff:ff:ff:ff
4: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel master virbr0 state DOWN group default qlen 1000
    link/ether 52:54:00:9e:18:58 brd ff:ff:ff:ff:ff:ff

注意，centos8之后网卡相关命令不是service network 了，相关可以查看
