mysql 最新的版本都需要cmake编译安装,估计以后的版本也会采用这种方式,所以特地记录一下安装步骤及过程,以供参考。 注意: 此安装是默认centos下已经安装了最新工具包,比如 GNU make , GCC , Perl , libncurses5-dev ,如果在编译安装过程中发现有缺失
mysql 最新的版本都需要cmake编译安装,估计以后的版本也会采用这种方式,所以特地记录一下安装步骤及过程,以供参考。
注意:此安装是默认centos下已经安装了最新工具包,比如GNU make, GCC, Perl, libncurses5-dev,如果在编译安装过程中发现有缺失的工具包,先yum install 单独下载安装再继续即可。
以下安装中涉及的几点需要提前说明的问题:
1. 所有下载的文件将保存在 /usr/local/src/ 目录下
2. mysql 将以mysql用户运行,而且将加入 service 开机自动运行
3. mysql 将被安装在 /usr/local/mysql/ 目录下
4. mysql 默认安装使用 utf8 字符集
5. mysql 的数据和日志文件保存在 /var/mysql/ 对应目录下
6. mysql 的配置文件保存于/var/mysql/my.cnf
一. Centos 用 wget 下载需要的软件,保存到目录 /usr/local/src/ 下
wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.23.tar.gz/from/http://mysql.he.net/
或者使用 wget http://mysql.he.net/Downloads/MySQL-5.5/mysql-5.5.23.tar.gz
wget http://www.cmake.org/files/v2.8/cmake-2.8.8.tar.gz
wget http://ftp.gnu.org/gnu/bison/bison-2.5.tar.gz
二. 安装 cmake
cd /usr/local/src
tar zxvf cmake-2.8.8.tar.gz
cd cmake-2.8.8
./bootstrap
gmake
gmake install
cd ../
tar zxvf bison-2.5.tar.gz
cd bison-2.5
./configure
make
make install
cd ../
三. 编译安装 MySQL 5.5.23
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar xvf mysql-5.5.23.tar.gz
cd mysql-5.5.23/
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/var/mysql/data
make
make install
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
ln -s /usr/local/mysql/lib/libmysqlclient.so.16 /usr/lib/libmysqlclient.so.16
mkdir -p /var/mysql/
mkdir -p /var/mysql/data/
mkdir -p /var/mysql/log/
chown -R mysql:mysql /var/mysql/
cd support-files/
cp my-large.cnf /var/mysql/my.cnf (注意:my-large.cnf适用于1G内存左右的服务器,可以根据自己配置情况选用my-large.cnf 或 my-huge.cnf 等不同配置)
cp mysql.server /etc/init.d/mysqld
四. 配置启动MySQL 5.5.23
1. 若有需要请先修改 mysql 的配置 my.cnf
vi /var/mysql/my.cnf
2. mysql 初始化安装
/usr/local/mysql/scripts/mysql_install_db \
--defaults-file=/var/mysql/my.cnf \
--basedir=/usr/local/mysql \
--datadir=/var/mysql/data \
--user=mysql
3. 将 mysql 加入开机启动
chmod +x /etc/init.d/mysqld
vi /etc/init.d/mysqld (编辑此文件,查找并修改以下变量内容:)
basedir=/usr/local/mysql
datadir=/var/mysql/data
chkconfig --add mysqld
chkconfig --level 345 mysqld on
4. 启动 mysql
service mysqld start

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
