bitsCN.com fedora 16下mysql(rpm)安装使用手册lychee 安装Mysql 1、下载MySQL的安装文件 安装MySQL需要下面两个文件:MySQL-client-5.1.55-1.glibc23.i386.rpmMySQL-server-5.1.55-1.glibc23.i386.rpm下载地址为:http://mirrors.sohu.com/mysql/MySQL-5.1/可以使用: yum install mysql-server 进行安装 2、安装MySQLrpm文件是Red Hat公司开发的软件安装包,rpm可让Linux在安装软件包时免除许多复杂的手续。该命令在安装时常用的参数是 –ivh ,其中i表示将安装指定的rmp软件包,V表示安装时的详细信息,h表示在安装期间出现“#”符号来显示目前的安装过程。这个符号将持续到安装完成后才停 止。1)安装服务器端 在有两个rmp文件的目录下运行如下命令: [root@test1 local]# rpm -ivh MySQL-server-5.1.55-1.glibc23.i386.rpm提醒:如果出现如下error: Failed dependencies: perl(DBI) is needed by MySQL-server-5.1.16-0.glibc23.i386请使用yum install perl-DBI安装一下即可,当然这要试不同的发行版而言的。显示如下信息。 warning: MySQL-server-5.1.55-1.glibc23.i386.rpmsignature: NOKEY, key ID 5072e1f5 Preparing... ########################################### [100%]1:MySQL-server ########################################### [100%] 。。。。。。(省略显示) /usr/bin/mysqladmin -u root password 'new-password' /usr/bin/mysqladmin -u root -h test1 password 'new-password' 。。。。。。(省略显示) Starting mysqld daemon with databases from /var/lib/mysql 如出现如上信息,服务端安装完毕。测试是否成功可运行netstat看Mysql端口是否打开,如打开表示服务已经启动,安装成功。Mysql默认的端口是3306。 [root@test1 local]# netstat -nat Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 上面显示可以看出MySQL服务已经启动。 2)安装客户端 运行如下命令: [root@test1 local]# rpm -ivh MySQL-client-5.1.55-1.glibc23.i386.rpm warning: MySQL-client-5.1.55-1.glibc23.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5 Preparing... ########################################### [100%]1:MySQL-client ########################################### [100%] 显示安装完毕。 用下面的命令连接mysql,测试是否成功。三、登录MySQL 登录MySQL的命令是mysql, mysql 的使用语法如下: mysql [-u username] [-h host] [-p[password]] [dbname] username 与 password 分别是 MySQL 的用户名与密码,mysql的初始管理帐号是root,没有密码,注意:这个root用户不是Linux的系统用户。MySQL默认用户是root,由于 初始没有密码,第一次进时只需键入mysql即可。[root@test1 local]# mysql Welcome to the MySQL monitor. Commands end with ; or /g. Your MySQL connection id is 1 to server version: 4.0.16-standard Type 'help;' or '/h' for help. Type '/c' to clear the buffer. mysql> 出现了“mysql>”提示符,恭喜你,安装成功! 增加了密码后的登录格式如下: mysql -u root -p Enter password: (输入密码) 其中-u后跟的是用户名,-p要求输入密码,回车后在输入密码处输入密码。 注意:这个mysql文件在/usr/bin目录下,与后面讲的启动文件/etc/init.d/mysql不是一个文件。 Linux下MYSQL设置密码和访问数据库:设置mysql数据库密码 [root@localhost ~]#mysqladmin -u root password "密码"访问mysql数据库命令: [root@localhost ~]#mysql -u root -p → 敲回车 输入密码 mysql使用rpm安装使用默认信息如下:1)数据库目录 /var/lib/mysql/2)配置文件 /usr/share/mysql (mysql.server命令及配置文件 )3)相关命令 /usr/bin/ (mysqladmin mysqldump)4)启动脚本 /etc/rc.d/init.d/5)默认端口是3306 作者 jiangliqing1234 bitsCN.com

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.

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.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

Setting up a MySQL connection pool using PHP can improve performance and scalability. The steps include: 1. Install the MySQLi extension; 2. Create a connection pool class; 3. Set the connection pool configuration; 4. Create a connection pool instance; 5. Obtain and release connections. With connection pooling, applications can avoid creating a new database connection for each request, thereby improving performance.

PHP provides the following methods to delete data in MySQL tables: DELETE statement: used to delete rows matching conditions from the table. TRUNCATETABLE statement: used to clear all data in the table, including auto-incremented IDs. Practical case: You can delete users from the database using HTML forms and PHP code. The form submits the user ID, and the PHP code uses the DELETE statement to delete the record matching the ID from the users table.
