在CentOS 6 中安装 Apache,Mysql, PHP
1.安装Apache
在终端中输入下面的命令就可以安装Apache了:
sudo yum install httpd
sudo的意思是用root用户做什么操作。要点击y就确认下载安装了,非常方便。
然后用下面的命令来启动服务
sudo service httpd start
现在不用着急往下弄,直接在浏览器中输入DigitalOcean给你的IP地址,应该就可以访问到Apache的欢迎页面了。类似下面的样子:
是不是很酷?如果你的域名已经成功解析到你主机的IP地址上的话,用你的域名应该也可以访问了!
2.安装Mysql
sudo yum install mysql-serversudo service mysqld start
用上面的命令就可以下载安装mysql了,第二条是启动mysql服务的意思。
安装mysql会询问你一些简单的配置,先按enter,后面的其实英文很简单,根据自己的需求来选。
Disallow root login remotely?有这样一条选项,是否允许mysql 的root用户远程访问,我是选择了no,可以访问,这样方便些,但存在安全隐患。这样后面做软件也可以使用这个VPS中的数据库了。3.安装PHP以及PHP组件
sudo yum install php php-mysql
用上面这个命令就可以下载安装PHP了。比较麻烦的是PHP的组件。
yum install php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
我这里简单的安装了7个组件,你也可以搜索所有的PHP组件,用下面的命令
yum search php-
4.开机默认启动Apache和Mysql服务
sudo chkconfig httpd onsudo chkconfig mysqld on
可以用上面两个命令来选择开机启动Apache和Mysql.
5.测试PHP是否安装成功
sudo nano /var/www/html/info.php
你可以用上面的命令来新建一个info.php文件,nano是简单的文本编辑工具,还有vim。
输入简单的测试PHP命令:
<?phpphpinfo ();?>
然后输入Ctrl o进行保存,点击回车确认。再输入Ctrl x进行退出。
然后在浏览器中,输入IP地址加上info.php,就可以看到PHP的信息了!类似下面的图:
只差安装Wordpress了,好兴奋。

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

Composer is a dependency management tool for PHP, and manages project dependencies through composer.json file. 1) parse composer.json to obtain dependency information; 2) parse dependencies to form a dependency tree; 3) download and install dependencies from Packagist to the vendor directory; 4) generate composer.lock file to lock the dependency version to ensure team consistency and project maintainability.

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.
