Day2 -- SecureCRT configuration, day2 -- securecrt

In production, we cannot see the working interface of the virtual machine. The virtual machine interface is equivalent to the display screen of the data center. In fact, we manage it in the operating tool. Here we use SecureCRT to remotely connect to the virtual machine, secureCRT settings are as follows:

1. Enable SecureCRT (Super Terminal), Click [quick link], as shown below:

2. Create a connection and set the Host Name and user name. The default port number is as follows:

3. A prompt box appears for the first time. Select "Receive and save". A dialog box is displayed, as shown in the following figure. Enter the password to log on:

 

4. The connection is successful, as shown below:

5. Set the session options as follows:

My settings are as follows:

 

(Configuration 1)

(Configuration 2)

5. Check the NIC configuration information. If ONBOOT is set to no, you need to [ifup eth0] Start the NIC every time you start the instance, as shown below:

6. Modify the NIC configuration information so that ONBOOT = yes. In this way, you do not need to start the NIC (ifup eth0) every time you start the NIC, as shown below:

Use sed-I's # ONBOOT = no # ONBOOT = yes # G'/etc/sysconfig/Network-scripts/Ifcfg-eth0, Modify the NIC configuration information
