MySQL 5.5.22源码编译安装
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 /data/mysql/ 对应目录下
6. mysql 的配置文件保存于/etc/my.cnf
一. Centos 用 wget 下载需要的软件,保存到目录 /usr/local/src/ 下
wget ://mysql.he.net/
wget
wget
二. 安装 cmake
cd /usr/local/src
tar zxvf cmake-2.8.7.tar.gz
cd cmake-2.8.7
./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 5.5.22
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar xzvf mysql-5.5.22.tar.gz
cd mysql-5.5.22/
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DENABLED_LOCAL_INFILE=1 -DMYSQL_DATADIR=/data/mysql -DMYSQL_USER=mysql
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 /etc/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 5.5.22
1. 若有需要请先修改 mysql 的配置 my.cnf
vi /etc/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

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
