linux 安装mysql数据库tar.gz包解压安装法_MySQL
mysql数据库有多种安装方式,本文只介绍在Linux服务器上的tar.gz包解压安装法,
先通过mysql官网或者网络资源下载 mysql-5.7.3-m13-linux-glibc2.5-x86_64.tar.gz(后缀为tar.gz已编译好的安装文件)
1、首先新建mysql用户# useradd mysql 并设置禁止mysql登录服务权限 # usermod -s /sbin/nologin mysql
2、将下载好的tar.gz文件通过xftp(或则其他工具上传到需要安装的服务器)
3、在# cd usr/local/目录下新建一个文件夹(mysqlService)# mkdir mysqlService
4、回到上传的目录下将 tar.gz文件移动到在# cd usr/local/mysqlService下
# cp -r mysql-5.7.3-m13-linux-glibc2.5-x86_64.tar.gz /usr/local/mysqlService/mysql-5.7.3-m13-linux-glibc2.5-x86_64.tar.gz
5、解压命令格式:tar -zxvf 压缩文件名.tar.gz # tar -zxvf apache-tomcat-7.0.64.tar.gz
6、修改文件名 [root@int02 mysqlService]# mv mysql-5.7.3-m13-linux-glibc2.5-x86_64 mysql
7、添加mysql组和mysql用户,用于设置mysql安装目录文件所有者和所属组。
[root@int02 mysqlService]# groupadd mysql
[root@int02 mysqlService]# useradd -r -g mysql mysql
9、进入mysql文件夹,也就是mysql所在的目录,并更改所属的组和用户。
10、[root@int02 mysql]# chown -R mysql:mysql ./
检查当前目录下是什么是不是在编译安装完的mysql程序的目录中,在该目录下有没有下scripts,然后再检查下scripts/目录下有没有mysql_install_db这个文件,还有这个文件是不是有执行的权限
[root@int02 mysql]# ./scripts/mysql_install_db --user=mysql
11、把当前目录下的文件及目录的属主改为root用户。
[root@int02 mysql]# chown -R root:root ./
把mysql_data文件夹的属主改为mysql用户。
[root@int02 mysql]# chown -R mysql:mysql data
把配置文件cope到/etc/init.d/目录下
[root@int02 mysql]# cp support-files/mysql.server /etc/init.d/mysql
在安装目录下新建一个log/mysqld.log目录
12、修改下配置文件 [root@int02 mysql]# vim /etc/my.cnf
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
datadir=/usr/local/mysqlService/mysql/data
basedir=/usr/local/mysqlService/mysql
socket=/tmp/mysql.sock
[mysqld_safe]
log-error=/usr/local/mysqlService/mysql/log/mysqld.log
13、检查相关文件目录是否有足够权限
# ll
若没有权限 则对需要的应文件进行赋权限
# chmod -R 755 mysqld.log
14、启动mysql服务
[root@int02 mysql]# service mysql start
停止mysql服务
[root@int02 mysql]# service mysql stop
15、查看服务进程
[root@int02 mysql]# ps -ef|grep mysql
查看mysql日志
[root@int02 mysql]# vi log/mysqld.log
16、登录数据库
密码:znjt3edcxsw2!@
[root@int02 mysql# bin/mysql -u root -p
退出
mysql> quit;

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

Analysis of the basic principles of the MySQL database management system MySQL is a commonly used relational database management system that uses structured query language (SQL) for data storage and management. This article will introduce the basic principles of the MySQL database management system, including database creation, data table design, data addition, deletion, modification, and other operations, and provide specific code examples. 1. Database Creation In MySQL, you first need to create a database instance to store data. The following code can create a file named "my

PHP is a back-end programming language widely used in website development. It has powerful database operation functions and is often used to interact with databases such as MySQL. However, due to the complexity of Chinese character encoding, problems often arise when dealing with Chinese garbled characters in the database. This article will introduce the skills and practices of PHP in handling Chinese garbled characters in databases, including common causes of garbled characters, solutions and specific code examples. Common reasons for garbled characters are incorrect database character set settings: the correct character set needs to be selected when creating the database, such as utf8 or u
