• linux基础命令


    1

    ① 命令行切换图形界面:startx &

    ② 显示文字转换命令行输入:localectl list-locales

                localectl set-locale LANG=zh_CN.utf8(反之en-US)查看语言locale
    ③ 查看所用shell类型:
    】#echo $SHELL

    2

    ① ssh协议secure shell:

          【root@test~】#ss -tnl

            (查看系统是否监听于TCP协议的22端口)
    查看ip(ifconfig)
    3
    ① 确保防火墙是否关闭:
    ~】#iptables -L -n
    centOS 7:(执行)
    ~】#systemctl disable firewalld.service(先禁用下一步再停止)
    #systemctl stop firewalld.service
    centOS 6:
    ]#service iptables stop
    ]#chkconfig iptables off
    4
    ①,基础命令:
    关机命令:
    centOS 7:
    】#systemctl poweroff(关机)
    ]#systemctl reboot(重启)

    ②普通命令语法格式:/bin,/usr/bin,/usrlocal/bin
    管理命令语法格式:/sbin,/usr/sbin,/usr/local/sbin

    共享库:/lib,/lib64,/usr/bin,/usr/local64,/usr/local/lib,/usr/local/lib64
    32tits的库:/lib,/usr/lib,/usr/local/lib
    64bits的库:/lib64,/usr/lib64,/usr/local/lib64

     liunx设置静态IP

    编辑 ifcfg-eth0 文件,vim 最小化安装时没有被安装,需要自行安装不描述。

      # vim /etc/sysconfig/network-scripts/ifcfg-eth0 

    修改如下内容

      

    1 BOOTPROTO="static" #dhcp改为static   
    2 ONBOOT="yes" #开机启用本配置  
    3 IPADDR=192.168.7.106 #静态IP  
    4 GATEWAY=192.168.7.1 #默认网关  
    5 NETMASK=255.255.255.0 #子网掩码  
    6 DNS1=192.168.7.1 #DNS 配置 

    修改后效果

     1 # ]# cat /etc/sysconfig/network-scripts/ifcfg-eth0  
     2 HWADDR="00:15:5D:07:F1:02"  
     3 TYPE="Ethernet"  
     4 BOOTPROTO="static" #dhcp改为static   
     5 DEFROUTE="yes"  
     6 PEERDNS="yes"  
     7 PEERROUTES="yes"  
     8 IPV4_FAILURE_FATAL="no"  
     9 IPV6INIT="yes"  
    10 IPV6_AUTOCONF="yes"  
    11 IPV6_DEFROUTE="yes"  
    12 IPV6_PEERDNS="yes"  
    13 IPV6_PEERROUTES="yes"  
    14 IPV6_FAILURE_FATAL="no"  
    15 NAME="eth0"  
    16 UUID="bb3a302d-dc46-461a-881e-d46cafd0eb71"  
    17 ONBOOT="yes" #开机启用本配置  
    18 IPADDR=192.168.7.106 #静态IP  
    19 GATEWAY=192.168.7.1 #默认网关  
    20 NETMASK=255.255.255.0 #子网掩码  
    21 DNS1=192.168.7.1 #DNS 配置  

    重启下网络服务

    # service network restart 

    查看改动后的效果,Centois 7 不再使用 ifconfig 而是用 ip 命令查看网络信息。

     1 # ip addr  
     2 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN   
     3     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00  
     4     inet 127.0.0.1/8 scope host lo  
     5        valid_lft forever preferred_lft forever  
     6     inet6 ::1/128 scope host   
     7        valid_lft forever preferred_lft forever  
     8 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000  
     9     link/ether 00:15:5d:07:f1:02 brd ff:ff:ff:ff:ff:ff  
    10     inet 192.168.7.106/24 brd 192.168.7.255 scope global eth0  
    11        valid_lft forever preferred_lft forever  
    12     inet6 fe80::215:5dff:fe07:f102/64 scope link   
    13        valid_lft forever preferred_lft forever
