1.Linux下编译安装MySQL问题:
(1) ../depcomp: line 571: exec: g++: not found
make[1]: *** [my_new.o] 错误 127
make[1]: Leaving directory `/home/justme/software/mysql-5.1.30/mysys'
make: *** [all-recursive] 错误 1
这个问题原因是缺少g++编译器,解决方法是安装gcc-c++-4.1.2-33.i386.rpm套件。在安装过程中可能其还需要依赖套件libstdc++-devel-3.4.6-3.1.i386.rpm。所以解决途径为:
一) 先安装libstdc++-devel-3.4.6-3.1.i386.rpm
二) 再安装gcc-c++-4.1.2-33.i386.rpm
(2) error: redeclaration of C++ built-in type
出现该问题的原因是重新安装gcc-c++后没有重新执行.configure命令。因此解决途径为:
一) 重新执行 ./configure –prefix=/usr/local/mysql
二) 再执行make
(3) 启动MySQL时报错:
[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
[ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.host' doesn't exist
这个错误的原因是用mysql用户去启动,但是查看下var/mysql 下plugin表的所有者是root,故没有权限去执行。执行chown -R mysql var可以解决问题。
附:编译安装MySQL的步骤
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> gunzip shell> cd mysql-VERSION
shell> ./configure --prefix=/usr/local/mysql
shell> make
shell> make install
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> cd /usr/local/mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> bin/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql var
shell> bin/mysqld_safe --user=mysql &
将mysql的执行路径添加到root用户的环境变量中:
shell> vi ~/.bash_profile
修改PATH变量:
PATH=$PATH:$HOME/bin:/usr/local/mysql/bin/
让修改马上生效,,可以执行如下命令:source ~/.bash_profile(或者. ~/.bash_profile)

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.

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.

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.

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

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

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())
