  在Linux服务器lvs负载均衡、双机热备应用中经常用到MySQL双机热备,安装和配置过程如下:

  一、 安装MySQL

  # cp mysql-standard-4.1.9-pc-linux-gnu-i686.tar.gz /usr/local/

  # tar zxvf mysql-standard-4.1.9-pc-linux-gnu-i686.tar.gz

  # mv mysql-standard-4.1.9-pc-linux-gnu-i686 mysql

  # cd mysql

  # more INSTALL-BINARY

  查看安装文档,注意以红色框内为主。

  # groupadd mysql (建立mysql组)

  # useradd -g mysql mysql (建立mysql用户并将其用户加入该组)

  # scripts/mysql_install_db --user=mysql (以mysql用户身份执行数据库初始化安装脚本)

  # chown -R root . (归属root权限为当前目录)

  # chown -R mysql data (归属mysql权限为data目录)

  # chgrp -R mysql . (改变mysql档案/目录的使用者与群组拥有人为当前目录)

  # bin/mysqld_safe --user=mysql & (以mysql用户身份后台启动mysql数据库进程)

  之后我们就可以启动mysql数据库,,如图:

  显示为上述图,表示安装正确。

  为了使数据库更加安全,我们来设置数据库密码。

  如在下次启动服务器时能自动启动mysql数据库进程,我们还需写入/etc/rc.d/rc.local文件里

  echo “/usr/local/mysql/bin/mysqld_safe --user=mysql &” >;>; /etc/rc.d/rc.local

How do you handle database upgrades in MySQL?How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

What are the different backup strategies you can use for MySQL?What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

How to use MySQL functions for data processing and calculationHow to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PM

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

An efficient way to batch insert data in MySQLAn efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PM

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
