1.下载MySQL下载地址,选择要下载的版本,建议选择DMG安装包,用着比较方便。

2.解压并安装DMG包中的mysql-5.6.12-osx10.7-x86_64.pkg,然后安装MySQLStartupItem.pkg。

#注 MySQL的Mac OS X PKG安装到/usr/local/mysql-VERSION,并且还会安装一个符号连接,/usr/local/mysql,指向新的位置。如果有/usr/local/mysql目录,首先将它改名为/usr/local/mysql.bak。安装完后,安装器执行mysql_install_db在MySQL数据库中创建授权表。

安装布局与tar文件二进制分发版类似;所有MySQL二进制代码位于目录/usr/local/mysql/bin中。默认情况,MySQL套接字文件创建为/tmp/mysql.sock。 如果你想在系统启动过程中自动启动MySQL,你还需要安装MySQL Startup Item。在MySQL 5.1中,它是Mac OS X安装盘映像的一部分,是一个独立的安装软件包。只需要双击MySQLStartupItem.图标并按照说明来安装。

MySQL 5.1的Startup Item安装在/Library/StartupItems/MySQLCOM。Startup Item安装时在系统配置文件/etc/hostconfig中加入变量MySQLCOM=-YES-。如果你想要disable自动启动MySQL,只需要将该变量更改为MySQLCOM=-NO-。 安装完后,可以在终端窗口运行下面的命令来启动MySQL。你必须具有管理员权限来执行该任务。

3.如果你已经安装的Startup Item:


shell> sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
(Enter your password, if necessary)
(Press Control-D or enter "exit" to exit the shell)

如果不使用Startup Item,输入下面的命令序列:


shell> cd /usr/local/mysql
shell> sudo ./bin/mysqld_safe
(Enter your password, if necessary)
(Press Control-Z)
shell> bg
(Press Control-D or enter "exit" to exit the shell)

4.运行/usr/local/mysql/bin/mysql。


#注 如果出现Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)错误:
cd /usr/local/mysql/bin/mysql

修改该文件夹下my.cnf文件 添加socket = /tmp/mysql.sock

What are stored procedures in MySQL?What are stored procedures in MySQL?May 01, 2025 am 12:27 AM

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

How does query caching work in MySQL?How does query caching work in MySQL?May 01, 2025 am 12:26 AM

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

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.
