mysql安装
mysql是linux平台下最流行的数据库系统,今天介绍的是mysql的安装及简单的操作方法!
groupadd mysql //建立mysql用户组 useradd -g mysql mysql //建立mysql帐户 tar -zxvf mysql-x.x.xx.tar.gz //解压缩mysql cd mysql-5.0.45 //进入解压好的mysql目录 ./configure –prefix=/usr/local/mysql –with-charset=utf8 –with-collation=utf8_general_ci –with-extra-charsets=latin1 //设置参数 make make install //开始安装 cp support-files/my-medium.cnf /etc/my.cnf //拷贝my-medium.cnf文件到/etc/目录下并重命名为my.cnf |
用编辑器打开my.cnf文件,找到log-bin=mysql-bin这一行,将其注释掉
:#log-bin=mysql-bin
cd /usr/local/mysql //进入mysql目录 bin/mysql_install_db --user=mysql chown -R root . //设置目录权限属性 chown -R mysql /usr/local/mysql/var chgrp -R mysql bin/mysqld_safe --user=mysql & //启动mysql |
用编辑器打开/etc/rc.local文件,在exit 0前面加上,/usr/local/mysql/bin/mysqld_safe –user=mysql &
重新启动,输入mysql,如果能进入则说明启动成功!
——————————-mysql常用命令————————
mysql -uroot -p //登陆本机mysql、root为用户名 mysqladmin -uroot -p password 1234 //1234为新密码 create database mydb; //新建一个名为mydb的数据库 drop database mydb //删除一个名为mydb的数据库 show databases //查看数据库 desc func //查看数据表的详细结构 |
—————————–关键的,常用数据库维护操作————
mysqldump -uroot -p -all -database>/Users/venmos/backup.sql //备份全部数据库到/Users/venmos/目录下的backup.sql文件 mysqldump -uroot -p mydb>/Users/venmos/backup.sql //备份mydb数据库到/Users/venmos/目录下的backup.sql文件 use /Users/venmos/backup.sql //导入/Users/venmos/目录的backup.sql数据库 |
以上就是关于mysql的安装以及简单的操作方法,希望对大家有用!

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.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

How to connect to MySQL using phpMyAdmin? The URL to access phpMyAdmin is usually http://localhost/phpmyadmin or http://[your server IP address]/phpmyadmin. Enter your MySQL username and password. Select the database you want to connect to. Click the "Connection" button to establish a connection.
