什么是LAMP？

LAMP是Linux，Apache，MySQL和PHP的缩写。它是一堆应用程序的堆栈，它们在Web服务器上一起工作以托管网站。话虽如此，每个程序都有不同的目的：

在LAMP中， Linux 用作处理计算机上所有命令的服务器操作系统。在本文中，将使用CentOS 7发行版。

Apache 是一种Web服务器软件，可管理HTTP请求以传递您的网站内容。
MySQL 是关系数据库管理系统（RDBMS），其功能是在服务器上维护用户数据。
PHP 是用于服务器端通信的脚本语言。

版本信息：

在示例步骤中使用了以下版本的软件。操作时，请您以实际软件版本为准。

CentOS7：7.5.1804(最小化安装)
Apache：2.4.6
MySQL：5.7.31
PHP：7.0.33

环境准备。

查看系统版本。

更新所有更新包，但不更新内核。

1	`[root@wencheng ~]# yum --exclude=kernel* --exclude=centos-release* update -y`

第一部分：YUM安装

步骤一：YUM安装Apache

[root@wencheng ~]# yum -y install httpd httpd-manual mod_ssl mod_perl mod_auth_mysql　　　　//安装Apache服务及扩展包
 
[root@wencheng ~]# httpd -v　　　　//查看版本信息
Server version: Apache/2.4.6 (CentOS)
Server built:   Nov 16 2020 16:18:20
 
[root@wencheng ~]# systemctl start httpd　　　　//启动Apache服务器
 
[root@wencheng ~]# systemctl enable httpd　　　　//设置Apache开机自启动
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

查看安装结果。

在本地机器浏览器地址中，输入http://IP (搭建Apacha服务机器的IP)，若返回页面如下图，即Apache服务启动成功。

步骤二：YUM安装并配置MySQL

[root@wencheng ~]# rpm -Uvh  http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm　　　　//更新YUM源
 
[root@wencheng ~]# yum -y install mysql-community-server　　　　//安装MySQL
 
[root@wencheng ~]# mysql -V　　　　//查看MySQL版本
mysql  Ver 14.14 Distrib 5.7.34, for Linux (x86_64) using  EditLine wrapper
 
[root@wencheng ~]# systemctl start mysqld　　　　//启动MySQL
 
[root@wencheng ~]# systemctl enable mysqld　　　　//设置开机自启动
[root@wencheng ~]# systemctl daemon-reload
 
[root@wencheng ~]# grep password /var/log/mysqld.log　　　　//查看MySQL初始密码
2021-04-27T06:24:20.509347Z 1 [Note] A temporary password is generated for root@localhost: 8kfepaL?l,#x
 
[root@wencheng ~]# mysql_secure_installation　　　　//配置MySQL的安全性
 
Securing the MySQL server deployment.
 
Enter password for user root:　　　　　　//输入上一步获取的root用户初始密码(8kfepaL?l,#x)
 
The existing password for the user account root has expired. Please set a new password.
 
New password:　　　　//输入新密码，长度为8至30个字符，必须同时包含大小写英文字母、数字和特殊符号Re-enter new password:
 
Re-enter new password:　　　　//再次输入新密码
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration
of the plugin.
Using existing password for root.
 
Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : y
 
New password:　　　　//输入新密码，长度为8至30个字符，必须同时包含大小写英文字母、数字和特殊符号
 
Re-enter new password:　　　　//再次输入新密码
 
Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y　　　　//是否继续使用所提供的密码，输入Y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.
 
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y　　　　//是否删除匿名用户，输入Y
Success.
 
 
Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.
 
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y　　　　//禁止root远程登录，输入Y
Success.
 
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.
 
 
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y　　　　//是否删除test库和对它的访问权限，输入Y
 - Dropping test database...
Success.
 
 - Removing privileges on test database...
Success.
 
Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.
 
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y　　　　//是否重新加载授权表，输入Y
Success.
 
All done

步骤二：编译安装MySQL

解压并编译安装(注：内存>8G)。

[root@wencheng ~]# wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.bz2
[root@wencheng ~]# tar xf boost_1_59_0.tar.gz -C /usr/local/app/mysql/boost
[root@wencheng ~]# tar xf mysql-5.7.31.tar.gz -C /usr/local/src/
[root@wencheng ~]# cd /usr/local/src/mysql-5.7.31
 
[root@wencheng mysql-5.7.31]# yum install -y cmake openssl-devel bison*
 
[root@wencheng mysql-5.7.31]# cmake . \
> -DCMAKE_INSTALL_PREFIX=/usr/local/app/mysql \
> -DMYSQL_DATADIR=/usr/local/app/mysql/data \
> -DSYSCONFDIR=/etc \
> -DDEFAULT_CHARSET=utf8mb4 \
> -DENABLED_LOCAL_INFILE=1 \
> -DWITH_BOOST=/usr/local/app/mysql/boost \
> -DEXTRA_CHARSETS=all
说明：
-DCMAKE_INSTALL_PREFIX：mysql安装目录
-DMYSQL_DATADIR：数据存放目录
-DSYSCONFDIR：my.cnf配置文件目录
-DEFAULT_CHARSET：数据库默认字符编码
-DENABLED_LOCAL_INFILE：允许从本文件导入数据
-DWITH_BOOST=/usr/local/app/mysql/boost: boost源码路径
-DEXTRA_CHARSETS：安装所有字符集

注：更多预编译配置参数请参考mysql官方文档说明：https://dev.mysql.com/doc/refman/5.7/en/source-configuration-options.html#cmake-general-options
