To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/local/mysql56/bin/mysqladmin -u root password 'new-password'
/usr/local/mysql56/bin/mysqladmin -u root -h 472322.ea.com password 'new-password'
Alternatively you can run:
/usr/local/mysql56/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; /usr/local/mysql56/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script!

Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as /usr/local/mysql56/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server

解决原因是:
/usr/local/mysql跟目录需要赋予mysql权限
根据日志文件显示,首先检查运行权限,再看一下/usr/local/mysql/mysql.sock,发现/usr/local/mysql目录下并没有该文件,是否是没有权限写目录?
看到/usr/local/mysql目录是root用户,所以赋予mysql操作权限。

InnoDB使用redologs和undologs确保数据一致性和可靠性。1.redologs记录数据页修改,确保崩溃恢复和事务持久性。2.undologs记录数据原始值,支持事务回滚和MVCC。

EXPLAIN命令的关键指标包括type、key、rows和Extra。1)type反映查询的访问类型,值越高效率越高,如const优于ALL。2)key显示使用的索引,NULL表示无索引。3)rows预估扫描行数,影响查询性能。4)Extra提供额外信息,如Usingfilesort提示需要优化。

Usingtemporary在MySQL查询中表示需要创建临时表,常见于使用DISTINCT、GROUPBY或非索引列的ORDERBY。可以通过优化索引和重写查询避免其出现,提升查询性能。具体来说,Usingtemporary出现在EXPLAIN输出中时,意味着MySQL需要创建临时表来处理查询。这通常发生在以下情况:1)使用DISTINCT或GROUPBY时进行去重或分组;2)ORDERBY包含非索引列时进行排序;3)使用复杂的子查询或联接操作。优化方法包括:1)为ORDERBY和GROUPB

MySQL/InnoDB支持四种事务隔离级别:ReadUncommitted、ReadCommitted、RepeatableRead和Serializable。1.ReadUncommitted允许读取未提交数据,可能导致脏读。2.ReadCommitted避免脏读,但可能发生不可重复读。3.RepeatableRead是默认级别,避免脏读和不可重复读,但可能发生幻读。4.Serializable避免所有并发问题,但降低并发性。选择合适的隔离级别需平衡数据一致性和性能需求。

MySQL适合Web应用和内容管理系统,因其开源、高性能和易用性而受欢迎。1)与PostgreSQL相比,MySQL在简单查询和高并发读操作上表现更好。2)相较Oracle,MySQL因开源和低成本更受中小企业青睐。3)对比MicrosoftSQLServer,MySQL更适合跨平台应用。4)与MongoDB不同,MySQL更适用于结构化数据和事务处理。

MySQL索引基数对查询性能有显着影响:1.高基数索引能更有效地缩小数据范围,提高查询效率;2.低基数索引可能导致全表扫描,降低查询性能;3.在联合索引中,应将高基数列放在前面以优化查询。

MySQL学习路径包括基础知识、核心概念、使用示例和优化技巧。1)了解表、行、列、SQL查询等基础概念。2)学习MySQL的定义、工作原理和优势。3)掌握基本CRUD操作和高级用法,如索引和存储过程。4)熟悉常见错误调试和性能优化建议,如合理使用索引和优化查询。通过这些步骤,你将全面掌握MySQL的使用和优化。

MySQL在现实世界的应用包括基础数据库设计和复杂查询优化。1)基本用法:用于存储和管理用户数据,如插入、查询、更新和删除用户信息。2)高级用法:处理复杂业务逻辑,如电子商务平台的订单和库存管理。3)性能优化:通过合理使用索引、分区表和查询缓存来提升性能。
