Linux CentOS安装配置MySQL数据库
没什么好说的,直接正面刚吧。
安装mysql数据库
a)下载mysql源安装包:wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
b)安装mysql源:yum localinstall mysql57-community-release-el7-8.noarch.rpm
若结尾出现complete!,则说明MySQL源安装完成
c)检测是否安装完成:yum repolist enabled | grep "mysql.*-community.*"
d)安装mysql:yum install mysql-community-server
若结尾出现Complete!, 则MySQL安装完成
e)设置开启启动mysql服务:systemctl enable mysqld
f)查看安装的mysql版本:rpm -aq | grep -i mysql
g)启动MySQL服务:systemctl restart mysqld
h)查看MySQL初始密码:grep 'A temporary password' /var/log/mysqld.log
i)更改MySQL密码:mysqladmin -u root -p'旧密码' password '新密码'
这里更改密码出了问题,更改失败,这是因为密码太过简单的原因。有两个接解决方法:
方法一:把密码设置复杂点(这是最直接的方法)
方法二:关闭mysql密码强度验证(validate_password)
编辑配置文件:vim /etc/my.cnf, 增加这么一行validate_password=off
编辑后重启mysql服务:systemctl restart mysqld
j)设置mysql能够远程访问:
登录进MySQL:mysql -uroot -p密码
增加一个用户给予访问权限:grant all privileges on *.* to 'root'@'ip地址' identified by '密码' with grant option; //可将ip改为%%,表示开启所有的
刷新权限:flush privileges;
OK,我本地连接试下。
好了,到这里就结束了,祝大家别出BUG。

Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.

MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database.

Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
