This article describes how to build a highly available MongoDB database on a Debian system. We will explore multiple ways to ensure data security and services continue to operate. Key strategy: ReplicaSet: ReplicaSet: Use replicasets to achieve data redundancy and automatic failover. When a master node fails, the replica set will automatically elect a new master node to ensure the continuous availability of the service. Data backup and recovery: Regularly use the mongodump command to backup the database and formulate effective recovery strategies to deal with the risk of data loss. Monitoring and Alarms: Deploy monitoring tools (such as Prometheus, Grafana) to monitor the running status of MongoDB in real time, and

This article introduces a variety of methods and tools to monitor PostgreSQL databases under the Debian system, helping you to fully grasp database performance monitoring. 1. Use PostgreSQL to build-in monitoring view PostgreSQL itself provides multiple views for monitoring database activities: pg_stat_activity: displays database activities in real time, including connections, queries, transactions and other information. pg_stat_replication: Monitors replication status, especially suitable for stream replication clusters. pg_stat_database: Provides database statistics, such as database size, transaction commit/rollback times and other key indicators. 2. Use log analysis tool pgBadg

The network configuration of the Debian system is mainly implemented through the /etc/network/interfaces file, which defines network interface parameters, such as IP address, gateway, and DNS server. Debian systems usually use ifup and ifdown commands to start and stop network interfaces. By modifying the ifeline in the interfaces file, you can set a static IP or use DHCP to dynamically obtain the IP address. It should be noted that Debian12 and subsequent versions no longer use NetworkManager by default, so other command-line tools, such as IP commands, may be required to manage network interfaces. You can edit /etc/netwo

Choose a secure mirror source to always download from the Debian official website or a reputable third-party mirror site. Priority is given to official certification or mirroring sources provided by large institutions. 3. Keep the system updates and installation immediately after running sudoaptupdate&&sudoaptupgrade to fix potential security vulnerabilities. It is recommended to install unattend

Mastering Debian system log monitoring is the key to efficient operation and maintenance. It can help you understand the system's operating conditions in a timely manner, quickly locate faults, and optimize system performance. This article will introduce several commonly used monitoring methods and tools. Monitoring system resources with the sysstat toolkit The sysstat toolkit provides a series of powerful command line tools for collecting, analyzing and reporting various system resource metrics, including CPU load, memory usage, disk I/O, network throughput, etc. The main tools include: sar: a comprehensive system resource statistics tool, covering CPU, memory, disk, network, etc. iostat: disk and CPU statistics. mpstat: Statistics of multi-core CPUs. pidsta
