在Linux上安装MySQL Server 5.0
我使用binary进行安装,文件名mysql-standard-5.0.18-linux-i686-glibc23.tar.gz [1]将上述文件解压到某处,并将MySQL所以目录名改为mysql,结果应如/home/jiang/mysql [2]根据mysql目录下的INSTALL-BINARY文件来进行安装 // 加用户组mysql,以及用户mysql;
我使用binary进行安装,文件名mysql-standard-5.0.18-linux-i686-glibc23.tar.gz
[1]将上述文件解压到某处,并将MySQL所以目录名改为mysql,结果应如/home/jiang/mysql
[2]根据mysql目录下的INSTALL-BINARY文件来进行安装
<p> // 加用户组mysql,以及用户mysql;该命令无需修改<br> shell> groupadd mysql<br> shell> useradd -g mysql mysql</p><p> // 以下三步的主要目的是为MySQL解压目录做一个链接,放到usr/local目录中<br> // 首先是进入/usr/local目录;该命令无需修改<br> shell> cd /usr/local<br> // 这一步可以不需要,因为已经解压了<br> shell> gunzip // 做一个到/home/jiang/mysql的链接,放在/usr/local中,该链接的名字是mysql。<br> // 该命令修改为ln -s /home/jiang/mysql mysql<br> shell> ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql </p><p> // 进入/home/jiang/mysql目录,/usr/local/mysql是到/home/jiang/mysql的链接<br> shell> cd mysql</p><p> // 对MySQL进行初始化(如果以前已经安装过MySQL,这一步可以简略);该命令无需修改<br> shell> scripts/mysql_install_db --user=mysql</p><p> // 变更所有权;该命令无需修改<br> shell> chown -R root .<br> shell> chown -R mysql data<br> shell> chgrp -R mysql .</p><p> // 启动MySQL服务器;该命令无需要修改<br> shell> bin/mysqld_safe --user=mysql &</p> Copy after login |
[3]进入MySQL应用环境
进入mysql目录下的bin目录,运行命令./mysql -u root -p,此时将出现password:(要求输入密码),但默认情况下root用户没有密码,所以回车即可。此时将进入MySQL界面,当然仍然只是个命令行窗口而以。
[4]简单使用MySQL
在MySQL环境中运行命令show databases;,将会显示已经有的数据库(如test);运行命令use test,将进入test数据库...
注意:如果在运行./mysql -u root -p之后,报
<p>Can't connect to local MySQL server through socket '/tem/mysql.sock'</p> Copy after login |
的错误,那么可能有以下几种情况:
[1]mysql.sock并不在/tmp目录下,而是在其它某个目录下(如,/var/lib/mysql目录)。这时只需要将这个mysql.sock做链接到/tmp目录下,运行命令:
<p>ln -s MYSQL.SOCK_PATH /tmp/mysql.sock</p> Copy after login |
[2]在同学的笔记本的Linux中,会在/tmp下生成mysql.sock,但重新启动Linux后,该文件被删除。这时也可以用情况2中的解决方法,或者每次都运行命令:
<p>./mysqld_safe --user=mysql &</p> Copy after login |

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

Although Notepad cannot run Java code directly, it can be achieved by using other tools: using the command line compiler (javac) to generate a bytecode file (filename.class). Use the Java interpreter (java) to interpret bytecode, execute the code, and output the result.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.
