Linux Environment Preparation

Linux Environment Preparation

• After installing Linux in VMware, log in with the root user
  

Configure the Network

2. Environment building of virtual machines
   Click Edit to open the virtual Network editor
   

   There are three network cards in it, VMnet0, VMnet1, VMnet8 are three different types
   Set VMnet1 to 0 network segment
   

   and configure NetworkAdapter as Host-only in virtual machine settings, that is, using NIC 1
   

   Configure VMnet1 network segments and virtual machines in the local network for consistent
   

   After the configuration is complete, open the cmd window and use the Ipconfig/all command to view the VMnet1 NIC
   

   Finally shut down the Windows Firewall.

4. IP address settings for Linux (terminal configuration is recommended)
   First, open in terminal, then enter the command Setup to enter the hardware configuration center. Select Network Configuration, click the Run tool,
   

   Select Device Configuration–>etho to enter the IP configuration page,

   Another way to configure:
   Edit the Ethernet card's configuration file by command Vim/etc/sysconfig/network-scripts/ifcfg-etho to display
   

   DEVICE：代表网卡名称HWADDR：网卡的物理地址，就是MAC地址TYPE：网卡的类型ONBOOT：开机网卡是否启动，改为yesBOOTPROTO：代表IP获取，dhcp为自动获取，static为静态网址，none，这里设置为static添加属性IPADDR=192.168.0.2NETMASK=255.255.255.0GATEWAY=192.168.0.1

   Can be viewed with the cat command after modification
   

   Restart the network via #/etc/init.d/network restart or # service network restart

   Modify Host Name

   命令：hostname -f 查看主机名            vim  /etc/sysconfig/network 修改主机名

   Configuring the host name and IP mapping relationship

   vim  /etc/hosts

   Restart takes effect

6. Test communication
   Ping Windows systems in a Linux system

   ping  192.168.0.100（是windows中的VMnet1的ip地址）

   Ping Linux Systems in Windows systems

   ping  192.168.0.2

8. SECURECRT use
   To connect quickly using the root user:
   
   

10. Turn off IP firewall
    

12. Installing the JDK
    Upload the JDK package to the root directory via Securefx and perform a named installation
    
    Configuring Environment variables

    # vim /etc/profile在配置文件最后一行添加：JAVA_HOME=/usr/java/jdk1.7.0_79export PATH=$JAVA_HOME/bin:$PATH生效命令：# source/etc/profile查看# java -version
