Percona 为 MySQL 数据库服务器进行了改进,在功能和性能上较 MySQL 有着很显著的提升。该版本提升了在高负载情况下的 InnoDB 的性能、为 DBA 提供一些非常有用的性能诊断工具;另外有更多的参数和命令来控制服务器行为。
2、特点 Percona Server 只包含 MySQL 的服务器版,并没有提供相应对 MySQL 的 Connector 和 GUI 工具进行改进。
Percona Server 使用了一些 google-mysql-tools, Proven Scaling, Open Query 对 MySQL 进行改造。
3、版本发布 2012年08月15日,Percona Server 5.6 Alpha 发布。
2012年08月23日,Percona Server 5.5.27-28.0 发布。
2013年04月11日,Percona Server for MySQL 5.5.30-30.2 发布

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h mysql2 password 'new-password'
Alternatively you can run:
/usr/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.

Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

二、配置Percona-Server
[root@mysql2 soft]# cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[root@mysql2 soft]# vi /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
explicit_defaults_for_timestamp=true
innodb_buffer_pool_size = 128M
join_buffer_size = 128M
sort_buffer_size = 2M
read_rnd_buffer_size = 2M
启动mysql服务:
[root@mysql2 soft]# service mysql start

-----问题解决!

在数据库优化中,应根据查询需求选择索引策略:1.当查询涉及多个列且条件顺序固定时,使用复合索引;2.当查询涉及多个列但条件顺序不固定时,使用多个单列索引。复合索引适用于优化多列查询,单列索引则适合单列查询。

要优化MySQL慢查询,需使用slowquerylog和performance_schema:1.启用slowquerylog并设置阈值,记录慢查询;2.利用performance_schema分析查询执行细节,找出性能瓶颈并优化。

MySQL和SQL是开发者必备技能。1.MySQL是开源的关系型数据库管理系统,SQL是用于管理和操作数据库的标准语言。2.MySQL通过高效的数据存储和检索功能支持多种存储引擎,SQL通过简单语句完成复杂数据操作。3.使用示例包括基本查询和高级查询,如按条件过滤和排序。4.常见错误包括语法错误和性能问题,可通过检查SQL语句和使用EXPLAIN命令优化。5.性能优化技巧包括使用索引、避免全表扫描、优化JOIN操作和提升代码可读性。

MySQL异步主从复制通过binlog实现数据同步,提升读性能和高可用性。1)主服务器记录变更到binlog;2)从服务器通过I/O线程读取binlog;3)从服务器的SQL线程应用binlog同步数据。

MySQL是一个开源的关系型数据库管理系统。1)创建数据库和表:使用CREATEDATABASE和CREATETABLE命令。2)基本操作:INSERT、UPDATE、DELETE和SELECT。3)高级操作:JOIN、子查询和事务处理。4)调试技巧:检查语法、数据类型和权限。5)优化建议:使用索引、避免SELECT*和使用事务。

MySQL的安装和基本操作包括:1.下载并安装MySQL,设置根用户密码;2.使用SQL命令创建数据库和表,如CREATEDATABASE和CREATETABLE;3.执行CRUD操作,使用INSERT,SELECT,UPDATE,DELETE命令;4.创建索引和存储过程以优化性能和实现复杂逻辑。通过这些步骤,你可以从零开始构建和管理MySQL数据库。

InnoDBBufferPool通过将数据和索引页加载到内存中来提升MySQL数据库的性能。1)数据页加载到BufferPool中,减少磁盘I/O。2)脏页被标记并定期刷新到磁盘。3)LRU算法管理数据页淘汰。4)预读机制提前加载可能需要的数据页。

MySQL适合初学者使用,因为它安装简单、功能强大且易于管理数据。1.安装和配置简单,适用于多种操作系统。2.支持基本操作如创建数据库和表、插入、查询、更新和删除数据。3.提供高级功能如JOIN操作和子查询。4.可以通过索引、查询优化和分表分区来提升性能。5.支持备份、恢复和安全措施,确保数据的安全和一致性。
