CentOS 6.5下编译安装MySQL 5.6.20
CentOS 6.5下通过yum安装的MySQL是5.1版的,比较老,所以就想通过源代码安装高版本的5.6.20。
概述:
CentOS 6.5下通过yum安装的MySQL是5.1版的,比较老,所以就想通过源代码安装高版本的5.6.20。
正文:
一:卸载旧版本
使用下面的命令检查是否安装有MySQL Server
rpm -qa | grep mysql有的话通过下面的命令来卸载掉
rpm -e mysql //普通删除模式
rpm -e --nodeps mysql // 强力删除模式,如果使用上面命令删除时,提示有依赖的其它文件,则用该命令可以对其进行强力删除二:安装MySQL
安装编译代码需要的包
yum -y install make gcc-c++ cmake bison-devel ncurses-devel下载MySQL 5.6.14
wget
tar xvf mysql-5.6.20.tar.gz
cd mysql-5.6.20编译安装
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLE_DOWNLOADS=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock \
-DMYSQL_TCP_PORT=3306 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci
make && make install编译的参数可以参考。
整个过程需要30分钟左右……漫长的等待
三:配置MySQL
设置权限
使用下面的命令查看是否有mysql用户及用户组
cat /etc/passwd 查看用户列表
cat /etc/group 查看用户组列表如果没有就创建
groupadd mysql
useradd -g mysql mysql修改/usr/local/mysql权限
chown -R mysql:mysql /usr/local/mysql修改/usr/local/mysql权限
初始化配置
进入安装路径
cd /usr/local/mysql进入安装路径,执行初始化配置脚本,创建系统自带的数据库和表
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql注:在启动MySQL服务时,会按照一定次序搜索my.cnf,先在/etc目录下找,找不到则会搜索"$basedir/my.cnf",,在本例中就是 /usr/local/mysql/my.cnf,这是新版MySQL的配置文件的默认位置!注意:在CentOS 6.4版操作系统的最小安装完成后,在/etc目录下会存在一个my.cnf,需要将此文件更名为其他的名字,如:/etc/my.cnf.bak,否则,该文件会干扰源码安装的MySQL的正确配置,造成无法启动。
启动MySQL
添加服务,拷贝服务脚本到init.d目录,并设置开机启动
cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
service mysql start --启动MySQL配置用户
MySQL启动成功后,root默认没有密码,我们需要设置root密码。
设置之前,我们需要先设置PATH,要不不能直接调用mysql
修改/etc/profile文件,在文件末尾添加
PATH=/usr/local/mysql/bin:$PATH
export PATH关闭文件,运行下面的命令,让配置立即生效
source /etc/profile现在,我们可以在终端内直接输入mysql进入,mysql的环境了
执行下面的命令修改root密码
mysql -uroot
mysql> SET PASSWORD = PASSWORD('123456');若要设置root用户可以远程访问,执行
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'172.16.%' IDENTIFIED BY 'password' WITH GRANT OPTION;红色的password为远程访问时,root用户的密码,可以和本地不同。
配置防火墙
防火墙的3306端口默认没有开启,若要远程访问,需要开启这个端口
打开/etc/sysconfig/iptables
在“-A INPUT –m state --state NEW –m tcp –p –dport 22 –j ACCEPT”,下添加:
-A INPUT -m state --state NEW -m tcp -p -dport 3306 -j ACCEPT然后保存,并关闭该文件,在终端内运行下面的命令,刷新防火墙配置:
service iptables restart OK,一切配置完毕,你可以访问你的MySQL了~

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.
