Linux下MySQL安装详解_MySQL
安装前期准备
1.需要mysql安装包,并解压,解压命令 tar -zxvf +压缩包名
2.将其复制到需要安装的位置
我打算安装到/usr/local/mysql目录下
3.创建mysql用户与mysql组,用于管理mysql
开始安装
1.配置安装等信息
./configure --prefix=/usr/local/mysql/ --with-charset=utf8 --with-extra-charsets=all --with-unix-socket-path=/usr/local/mysql/var/mysql.sock --with-named-curses-libs=/lib/libncursesw.so.5
查看安装配置参数方式./configure –help<br><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c160504/14623310U1GZ-11c06.jpg" class="lazy" alt="这里写图片描述" title="\"><br>配置常用参数说明:
参数 |
说明 |
---|---|
–prefix=/usr/local/mysql/ |
安装路径 |
–with-charset=utf8 |
mysql默认字符集 |
with-extra-charsets=all |
支持多语言 |
–with-unix-socket-path=/usr/local/mysql/var/mysql.sock |
这个是指定mysql服务器启动后,联机套接字文件所处的位置和文件名,也就是说,如果CentOS mysql服务器成功启动后,就能在//usr/local/mysql/mysql/var目录中看到mysql.sock文件。如果看不到,肯定是CentOS mysql启动不了 |
–with-named-curses-libs=/lib/libncursesw.so.5 |
为了让mysql能够识别出路径 |
mysql允许的字符集有<br><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c160504/14623310U50-124E9.jpg" class="lazy" alt="这里写图片描述" title="\"><br>配置完成界面如下<br><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c160504/14623310U6250-13c29.jpg" class="lazy" alt="这里写图片描述" title="\"><br>2.执行make命令<br>如果此时提示如下错误<br>No curses/termcap library found<br><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c160504/14623310UY060-141331.jpg" class="lazy" alt="这里写图片描述" title="\"><br>解决办法:<br>解决方式(CentOS)<br>yum list"grep ncurses<br>yum -y install ncurses-devel<br>最后界面如下<br><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c160504/14623310V1250-15SJ.jpg" class="lazy" alt="这里写图片描述" title="\"><br>3.执行make install 命令
4.创造mysql授权表<br>做了这些工作以后,还得创造CentOS mysql授权表,否则数据库也是启动不了。mysql安装的命令都安装到了/usr/local/mysql/bin这个目录中。<br>运行mysql_install_db命令过后,我们查看/usr/local/mysql就会发现,有个var的目录。这个目录,就是用来装所有数据库的位置,比如我们创建了xxpt的数据库后,就在在/usr/local/mysql/var目录中有xxpt的目录。<br><img src="/static/imghw/default1.png" data-src="http://img.bitscn.com/upimg/allimg/c160504/14623310V3Z60-164517.jpg" class="lazy" alt="这里写图片描述" title="\">

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.

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.
