Linux CentOS6.5下编译安装MySQL 5.6.22【给力详细教程】
一、编译安装MySQL前的准备工作
安装编译源码所需的工具和库(安装过程注意有没出错)
yum install gcc gcc-c++ ncurses-devel perl
安装cmake,从http://www.cmake.org下载源码并编译安装
我下的版本:http://www.cmake.org/files/v3.0/cmake-3.0.2.tar.gz
cd /home tar xzvf cmake-3.0.2.tar.gz cd /home/cmake-3.0.2 ./bootstrap ; make ; make install cd ~
二、设置MySQL用户和组
新增mysql用户组
groupadd mysql
useradd -r -g mysql mysql
三、新建MySQL所需要的目录
新建mysql安装目录mkdir -p /usr/local/mysql
新建mysql数据库数据文件目录
mkdir -p /data/mysqldb
四、下载MySQL源码包并解压
从http://dev.mysql.com/downloads/mysql/直接下载源码,解压mysql-5.6.22.tar.gz(进去之后Source Code)cd /home tar -zxv -f mysql-5.6.22.tar.gz cd mysql-5.6.22
五、编译安装MySQL
从mysql5.5起,mysql源码安装开始使用cmake了,设置源码编译配置脚本。
-DCMAKE_INSTALL_PREFIX=dir_name | 设置mysql安装目录 |
-DMYSQL_UNIX_ADDR=file_name | 设置监听套接字路径,这必须是一个绝对路径名。默认为/tmp/mysql.sock |
-DDEFAULT_CHARSET=charset_name | 设置服务器的字符集。 缺省情况下,MySQL使用latin1的(CP1252西欧)字符集。cmake/character_sets.cmake文件包含允许的字符集名称列表。 |
-DDEFAULT_COLLATION=collation_name | 设置服务器的排序规则。 |
-DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_PERFSCHEMA_STORAGE_ENGINE=1 |
存储引擎选项: MyISAM,MERGE,MEMORY,和CSV引擎是默认编译到服务器中,并不需要明确地安装。 静态编译一个存储引擎到服务器,使用-DWITH_engine_STORAGE_ENGINE= 1 可用的存储引擎值有:ARCHIVE, BLACKHOLE, EXAMPLE, FEDERATED, INNOBASE (InnoDB), PARTITION (partitioning support), 和PERFSCHEMA (Performance Schema) |
-DMYSQL_DATADIR=dir_name | 设置mysql数据库文件目录 |
-DMYSQL_TCP_PORT=port_num | 设置mysql服务器监听端口,默认为3306 |
-DENABLE_DOWNLOADS=bool | 是否要下载可选的文件。例如,启用此选项(设置为1),cmake将下载谷歌所使用的测试套件运行单元测试。 |
设置编译参数
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=mysql.mysql -DDEFAULT_CHARSET=gbk -DDEFAULT_COLLATION=gbk_chinese_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data/mysqldb -DMYSQL_TCP_PORT=3306 -DENABLE_DOWNLOADS=1
注:重新运行配置,需要删除CMakeCache.txt文件
rm CMakeCache.txt
编译源码
make
安装
make install
六、修改mysql目录所有者和组
修改mysql安装目录cd /usr/local/mysql chown -R mysql:mysql .
修改mysql数据库文件目录
cd /data/mysqldb chown -R mysql:mysql .
七、初始化mysql数据库
cd /usr/local/mysql scripts/mysql_install_db --user=mysql --datadir=/data/mysqldb
八、复制mysql服务启动配置文件
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
注:如果/etc/my.cnf文件存在,则覆盖。
九、复制mysql服务启动脚本及加入PATH路径
下面这些一行一行的输
cp support-files/mysql.server /etc/init.d/mysqld vim /etc/profile PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH export PATH source /etc/profile
十、启动mysql服务并加入开机自启动(可选这个步骤,以后可以自己启动的)
service mysqld start chkconfig --level 35 mysqld on
十一、检查mysql服务是否启动
netstat -tulnp | grep 3306 mysql -u root -p
密码为空,如果能登陆上,则安装成功。
十二、修改MySQL用户root的密码
mysqladmin -u root password '123456'
注:也可运行安全设置脚本,修改MySQL用户root的密码,同时可禁止root远程连接,移除test数据库和匿名用户。
/usr/local/mysql/bin/mysql_secure_installation
十三、添加 MySQL用户
grant ALL PRIVILEGES on *.* to mysql@"%" Identified by "123456" WITH GRANT OPTION
十四、可能会出现的错误
问题:Starting MySQL..The server quit without updating PID file ([FAILED]/mysql/Server03.mylinux.com.pid).
解决:
修改/etc/my.cnf 中datadir,指向正确的mysql数据库文件目录
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
解决:
新建一个链接或在mysql中加入-S参数,直接指出mysql.sock位置。
ln -s /usr/local/mysql/data/mysql.sock /tmp/mysql.sock /usr/local/mysql/bin/mysql -u root -S /usr/local/mysql/data/mysql.sock
MySQL问题解决:-bash:mysql:command not found
因为mysql命令的路径在/usr/local/mysql/bin下面,所以你直接使用mysql命令时,
系统在/usr/bin下面查此命令,所以找不到了
解决办法是: 做个链接即可
ln -s /usr/local/mysql/bin/mysql /usr/bin

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
