切换命令行视图 init 3
init 常见命令
| 命令 | 含义 |
|---|---|
| init 0 | 停机 |
| init 1 | 单用户形式，只root进行维护 |
| init 2 | 多用户，不能使用net file system |
| init 3 | 完全多用户 |
| init 5 | 图形化 |
| init 6 | 重启 |
本文主要介绍 init 3多用户 命令行视图
1、鼠标右键点击Open Terminal
命令行窗口
2、输入init 3切换至命令行视图
3、会提示输入密码验证，点击Authenticate
调整到命令行视图，输入账号，密码即可
修改CentOS系统为静态获取，默认为dhcp获取
1、先切换到超级管理员用户
[janyxe@localhost ~]$ su
Password:
[root@localhost janyxe]#
2、编辑网卡命令
ifcfg-ens33为CentOS默认网卡
[root@localhost janyxe]# [root@localhost janyxe]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.162.126 netmask 255.255.255.0 broadcast 192.168.162.255
inet6 fe80::e8ba:b334:3292:5eef prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:e9:b9:08 txqueuelen 1000 (Ethernet)
RX packets 18649 bytes 24513805 (23.3 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 6938 bytes 451178 (440.6 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255
ether 52:54:00:13:1d:e9 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
3、CentOS默认为dhcp动态获取IP
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="0d0606e8-f3a4-41c6-b93a-3df3b1f7c160"
DEVICE="ens33"
ONBOOT="yes"
4、 ifconfig 查询当前网络信息
可看到ens33网卡通过dhcp获取到的ip
[root@localhost janyxe]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.162.126 netmask 255.255.255.0 broadcast 192.168.162.255
inet6 fe80::e8ba:b334:3292:5eef prefixlen 64 scopeid 0x20<link>
ether 00:0c:29:e9:b9:08 txqueuelen 1000 (Ethernet)
RX packets 18649 bytes 24513805 (23.3 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 6938 bytes 451178 (440.6 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1000 (Local Loopback)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
virbr0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255
ether 52:54:00:13:1d:e9 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
5、修改ens33 网卡信息
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="0d0606e8-f3a4-41c6-b93a-3df3b1f7c160"
DEVICE="ens33"
ONBOOT="yes"
IPADDR=192.168.162.126 # 自定义ip地址
NETMASK=255.255.255.0 # 网段 默认为24位
GATEWAY=192.168.162.2 # 指向宿主机网卡IP
DNS1=192.168.162.2 # 指向宿主机网卡IP
wq命令保存
6、systemctl restart network 命令重启网络
[root@localhost janyxe]# systemctl restart network
7、测试外网网络
[root@localhost janyxe]# ping www.baidu.com
PING www.a.shifen.com (14.215.177.38) 56(84) bytes of data.
