- Analysis of Red Hat Linux9 version network management and three network connection methods of VMware virtual machines
- This article uses Red Hat Linux9 version as an example to explain. The network management of Red Hat Linux 9 version is very comprehensive and network configuration changes can be made in many places. However, it should be noted that in version 9, users can make network configuration changes in the configuration file, but the system will not. Execute the changed command, which is executable in versions prior to version 9. Three types of network connections on VMware virtual machines: bridge mode: connect the network card on the host to the virtual network card Vmnet0 through a virtual hub. In bridge mode, the network cards of the virtual machine are connected to the virtual switch Vmnet0. When the virtual machine wants to access the Internet Is the Linux system easy to use when managing the Linux system and network? It is necessary to configure the virtual machine IP address, subnet segment, network segment, etc. with the host network.

For ordinary files and directories on the Linux system, there are three Types of permissions: rwx permissions, hidden attribute permissions and ACL permissions 1. rwx permissions (1) Use numbers to represent rwx permissions. r represents read permission; w represents write permission; x represents execution permission. The Linux system has three identities: owner (u), group (g) and other people (o). The Linux system uses 0 to indicate that permissions are turned off, and 1 to indicate that permissions are turned on. So how to install LINUX for any file?

- Use the sar tool to detect system performance bottlenecks
- The sar command is used to collect, report, or save UNIX/Linux system activity information. It saves selected counters to the operating system's /var/log/sa/sadd file. From the collected data, you can get a lot of information about your server: CPU usage, memory page and usage, network I/O and transfer statistics, process creation activity, all block device activity, number of interrupts per second, etc. The output of the sar command. Can be used to identify server bottlenecks. However, it can be difficult to analyze the information provided by the sar command, so use the kSar tool. The kSar tool can plot the output of the sar command into an easy-to-understand chart based on time periods. sysstat packages sar, sa1, and sa
