  • 【树莓派】树莓派网络配置:静态IP、无线网络、服务等

    一.网络配置之静态IP:

    树莓派的默认网络为:

    haochuang@raspberrypi:~ $ vi /etc/network/interfaces
    # interfaces(
    5) file used by ifup(8) and ifdown(8) # Please note that this file is written to be used with dhcpcd # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf' # Include files from /etc/network/interfaces.d: source-directory /etc/network/interfaces.d auto lo iface lo inet loopback iface eth0 inet manual allow-hotplug wlan0 iface wlan0 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf allow-hotplug wlan1 iface wlan1 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

    这个只要插上网线,即可自动获取到dhcp地址;

    但如果需要设置为静态IP,则需要简单进行设置一下,如下操作:

    haochuang@raspberrypi:~ $ vi /etc/dhcpcd.conf
    
    ......
    nohook lookup-hostname
    
    interface eth0
     static ip_address=192.168.21.103/24
     static routers=192.168.21.1
     static domain_name_servers=61.134.1.4 218.30.19.40

    设置完成之后,重启网络

    haochuang@raspberrypi:~ $ sudo /etc/init.d/networking restart

    二.配置无线网络:

    cat /etc/network/interfaces 

    auto lo  
      
    iface lo inet loopback  
    iface eth0 inet dhcp  
      
    #allow-hotplug wlan0  
    #iface wlan0 inet manual  
    #wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf  
    #iface default inet dhcp  
    auto wlan0  
    allow-hotplug wlan0  
    iface wlan0 inet dhcp  
            wpa-ssid "neu"  
            wpa-psk  "lucifer_chn"  

    或者

    # interfaces(5) file used by ifup(8) and ifdown(8)
    
    # Please note that this file is written to be used with dhcpcd
    # For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
    
    # Include files from /etc/network/interfaces.d:
    source-directory /etc/network/interfaces.d
    
    auto lo
    iface lo inet loopback
    
    #iface eth0 inet manual
    iface eth0 inet dhcp
    
    auto wlan0
    allow-hotplug wlan0
    #iface wlan0 inet manual
    #iface wlan0 inet dhcp
    #    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
    iface wlan0 inet static
      wpa-ssid "Chinanet"
      wpa-psk "CTshi555666"
      address 172.27.35.20 
      netmask 255.255.0.0
      gateway 172.27.35.1
    
    
    allow-hotplug wlan1
    iface wlan1 inet manual
        wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

    检查 /etc/wpa_supplicant/wpa_supplicant.conf 文件:

    country=GB
    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
    update_config=1
    
    network={
      ssid="Chinanet"
      psk="PWD-CTshi555666-passwd"
    }

    修改之后,重启即可;

    补充:

    配置无线动态IP:

    auto wlan0  
    allow-hotplug wlan0  
    iface wlan0 inet dhcp  
            wpa-ssid "name"  
            wpa-psk  "passwd" 

    配置无线静态IP:

    auto wlan0
    allow-hotplug wlan0
    iface wlan0 inet static
      wpa-ssid "name"
      wpa-psk "passwd"
      address 192.168.11.80
      netmask 255.255.255.0
      gateway 192.168.11.1

    三.增加用户的sudo权限:

    为普通用户增加sudo权限的方法,同其他一样,需要修改visudo文件,如下;

    haochuang@raspberrypi:~ $ sudo visudo

      GNU nano 2.2.6                                                  File: /etc/sudoers.tmp                                                                                                            
    
    #
    # This file MUST be edited with the 'visudo' command as root.
    #
    # Please consider adding local content in /etc/sudoers.d/ instead of
    # directly modifying this file.
    #
    # See the man page for details on how to write a sudoers file.
    #
    Defaults        env_reset
    Defaults        mail_badpass
    Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
    
    # Host alias specification
    
    # User alias specification
    
    # Cmnd alias specification
    
    # User privilege specification
    root    ALL=(ALL:ALL) ALL
    haochuang ALL=(ALL:ALL) ALL
    
    # Allow members of group sudo to execute any command
    %sudo   ALL=(ALL:ALL) ALL
    
    # See sudoers(5) for more information on "#include" directives:
    
    #includedir /etc/sudoers.d
    
    pi ALL=(ALL) NOPASSWD: ALL
    
    
    
    
    
                                                                                             [ Read 30 lines ]
    ^G Get Help                     ^O WriteOut                     ^R Read File                    ^Y Prev Page                    ^K Cut Text                     ^C Cur Pos
    ^X Exit                         ^J Justify                      ^W Where Is                     ^V Next Page                    ^U UnCut Text                   ^T To Spell

    增加其中标红的一行,并Ctrl+X,Yes保存退出;

    三.增加自动启动服务:

    1.编写自动启动脚本;

    haochuang@raspberrypi:~ $ sudo cat /etc/init.d/osprey 
    #!/bin/sh
    ### BEGIN INIT INFO
    # Provides:          osprey
    # Default-Start:     2 3 4 5
    # Default-Stop:      0 1 6
    # Required-Start: $local_fs
    # Required-Stop:
    # chkconfig: 12345 99 05
    # Short-Description: Start or stop the testapp App.
    ### END INIT INFO
    
    start(){
        echo -e "33[32m start testapp 33[0m"
        cd /home/haochuang/webapp/testapp
        su lifeccp -c "sh /home/haochuang/webapp/testapp/start --spring.profiles.active=test &"
    }
    
    stop(){
        echo -e "33[32m stop osprey 33[0m"
        pkill -f testapp
    
        app_pid=$(pgrep -f testapp)
        if [ "${app_pid}" = "" ]; then
            echo -e  "33[32m -=stop testapp finished=- 33[0m"
        else
            echo -e  "33[31m -=stop testapp failed=- 33[0m"
            kill -9 "${app_pid}"
            echo -e  "33[32m -=kill -9 testapp=- 33[0m"
        fi
    }
    
    case $1 in
    start)
        start
        ;;
    stop)
        stop
        ;;
    *)
        echo -e "33[32m Usage: $0 (start|stop) 33[0m"
        ;;
    esac

    注意上面脚本中的33[0m,其实是在为服务控制指令加色,想了解详细,可参考后面"其他"的补充描述;

    2.增加到 /etc/init.d中,并修改增加可执行权限;

    chomd +x testapp

    3.增加到启动项中

    chkconfig add /etc/init.d/testapp

    其他:

    颜色特效控制:

    printf("33[1;33m Hello World. 33[0m ");
    颜色如下:
    none = "33[0m"
    black = "33[0;30m"
    dark_gray = "33[1;30m"
    blue = "33[0;34m"
    light_blue = "33[1;34m"
    green = "33[0;32m"
    light_green -= "33[1;32m"
    cyan = "33[0;36m"
    light_cyan = "33[1;36m"
    red = "33[0;31m"
    light_red = "33[1;31m"
    purple = "33[0;35m"
    light_purple = "33[1;35m"
    brown = "33[0;33m"
    yellow = "33[1;33m"
    light_gray = "33[0;37m"
    white = "33[1;37m"

    字背景颜色范围: 40--49 字颜色: 30--39
    40: 黑 30: 黑
    41:红 31: 红
    42:绿 32: 绿
    43:黄 33: 黄
    44:蓝 34: 蓝
    45:紫 35: 紫
    46:深绿 36: 深绿
    47:白色 37: 白色

    输出特效格式控制:

    33[0m 关闭所有属性
    33[1m 设置高亮度
    3[4m 下划线
    33[5m 闪烁
    33[7m 反显
    33[8m 消隐
    33[30m -- 33[37m 设置前景色
    33[40m -- 33[47m 设置背景色

    光标位置等的格式控制:

    33[nA 光标上移n行
    3[nB 光标下移n行
    33[nC 光标右移n行
    33[nD 光标左移n行
    33[y;xH设置光标位置
    33[2J 清屏
    33[K 清除从光标到行尾的内容
    33[s 保存光标位置
    33[u 恢复光标位置
    33[?25l 隐藏光标
    33[?25h 显示光标
