CentOS is widely used in server management and web hosting. Specific methods include: 1) using yum and systemctl to manage the server, 2) install and configure Nginx for web hosting, 3) use top and mpstat to optimize performance, 4) correctly configure the firewall and manage disk space to avoid common problems.

CentOS is the first choice for server and enterprise environments for its superior security, stability and performance. 1) Security provides forced access control through SELinux to improve system security. 2) Stability is supported by the LTS version for up to 10 years to ensure the stability of the system. 3) Performance significantly improves system response speed and resource utilization by optimizing kernel and system configuration.

Alternatives to CentOS include UbuntuServer, Debian, Fedora, RockyLinux, and AlmaLinux. 1) UbuntuServer is suitable for basic operations, such as updating software packages and configuring the network. 2) Debian is suitable for advanced usage, such as using LXC to manage containers. 3) RockyLinux can optimize performance by adjusting kernel parameters.

CentOS is an open source distribution based on RedHatEnterpriseLinux, focusing on stability and long-term support, suitable for a variety of server environments. 1. The design philosophy of CentOS is stable and suitable for web, database and application servers. 2. Use YUM as the package manager to release security updates regularly. 3. Simple installation, you can build a web server with a few commands. 4. Advanced features include enhanced security using SELinux. 5. Frequently asked questions such as network configuration and software dependencies can be debugged through nmcli and yumdeplist commands. 6. Performance optimization suggestions include tuning kernel parameters and using a lightweight web server.

The end of CentOS has had a significant impact on users, with users having the option of RHEL, AlmaLinux, Debian or Ubuntu as alternatives. 1. The migration cost is high, requiring time and money. 2. Community division affects open source projects. 3.RHEL provides commercial support, but it is costly. 4.AlmaLinux is similar to CentOS and has low migration costs. 5. Debian and Ubuntu need more time to adapt.

CentOS needs alternatives because CentOSStream no longer provides long-term support. Alternative options include: 1. RockyLinux, which provides 10 years of life cycle support, suitable for users who need stability. 2.AlmaLinux also provides 10 years of support and has strong community support. 3. OracleLinux, provides RHEL-compatible version, and flexible life cycle management.

Alternatives to CentOS include AlmaLinux, RockyLinux, and OracleLinux. 1.AlmaLinux and RockyLinux rebuild RHEL 1:1, providing high stability and compatibility, suitable for enterprise environments. 2. OracleLinux provides high performance through UEK, suitable for users who are familiar with the Oracle technology stack. 3. When choosing, stability, community support and package management should be considered.
