Preface

The installation package is attached at the end of the installation package required in the article, see the end for details

1. LAMP overview

1.LAMP architecture

LAMP architecture is one of the current mature enterprise website application modes." It refers to a set of systems and related software that work together to provide dynamic website services and application development environments.
LAMP is an acronym that specifically includes Linux operating system , Apache web server, MySQL database server, PHP (or Perl, Python) web programming language.

2. The main function of LAMP components

(Platform)Linux: As the basis of the LAMP architecture, it provides an operating system to support the Web site, which can provide better stability and compatibility with the other three components (AMP components also support Windows, UNIX and other platforms).
(Foreground) Apache: As the front end of the LAMP architecture, it is a powerful and stable web server program. The server directly provides users with website access, sending web pages, pictures and other file content.
(Background) MySQL: As the back end of the LAMP architecture, it is a popular open source relational database system. In applications such as corporate websites and business systems, various account information, product information, customer information, business data, etc. can be stored in the MySQL database, and other programs can query and change this information through SQL statements.
(Intermediate connection) PHP/Perl/Python: As three programming languages ​​for developing dynamic webpages, it is responsible for interpreting dynamic webpage files, communicating with web servers and database systems to work together, and providing a development and operating environment for web applications. Among them, PHP is a widely used open source multi-purpose scripting language, which can be embedded in HTML, and is especially suitable for Web application development.
When building the LAMP platform, the order of installation of each component is Linux, Apache, MySQL, PHP. Among them, there is no strict order for the installation of Apache and MySQL. The installation of the PHP environment is generally placed at the end, responsible for communicating with the Web server and database system to work together.

2. Apache httpd service compilation and installation

#!/bin/bash												#在第一行前插入新行,添加此三行内容
# chkconfig: 35 85 21									#35级别自动运行  第85个启动 第21个关闭
# description: Apache is a World Wide Web server

chkconfig --add httpd     		#将httpd服务加入到service管理器

systemctl start httpd.service
或
service httpd start
Insert picture description here
方法二:
vim /lib/systemd/system/httpd.service
[Unit]
Description=The Apache HTTP Server						#描述
After=network.target									#描述服务类别
[Service]
Type=forking											#后台运行方式
PIDFile=/usr/local/httpd/logs/httpd.pid					#PID文件位置
ExecStart=/usr/local/bin/apachectl $OPTIONS				#启动服务
ExecReload=/bin/kill -HUP $MAINPID						#根据PID重载配置

Insert picture description here
Storage engine options:
MYISAM, MERGE, MEMORY, and CSV engines are compiled to the server by default and do not need to be explicitly installed. To statically compile a storage engine to the server, use -DWITH_engine_STORAGE_ENGINE=1. The available storage engine values ​​are: ARCHIVE, BLACKHOLE, EXAMPLE, FEDERATED, INNOBASE (InnoDB), PARTITION (partitioning support), and PERFSCHEMA (Performance Schema)

Note: If there is an error in the process of CMAKE, after the error is resolved, you need to delete the CMakeCache.txt file in the source directory, and then re-CMAKE, otherwise the error will remain

4. Compile and install

make -j  4  && make install

Insert picture description here

6. Modify the mysql configuration file

vim /etc/my.cnf								#删除原配置项,再重新添加下面内容
[client]									#客户端设置
port = 3306
socket = /usr/local/mysql/mysql.sock			

[mysql]										#服务端设置
port = 3306
socket = /usr/local/mysql/mysql.sock
auto-rehash									#开启自动补全功能

[mysqld]									#服务全局设置
user = mysql       							#设置管理用户
basedir=/usr/local/mysql					#指定数据库的安装目录
datadir=/usr/local/mysql/data				#指定数据库文件的存储路径
port = 3306									#指定端口
character-set-server=utf8					#设置服务器字符集编码格式为utf8
pid-file = /usr/local/mysql/mysqld.pid		#指定pid 进程文件路径
socket=/usr/local/mysql/mysql.sock			#指定数据库连接文件
bind-address = 0.0.0.0						#设置监听地址,0.0.0.0代表允许所有,如允许多个IP需空格隔开
skip-name-resolve							#禁用DNS解析
max_connections=2048						#设置mysql的最大连接数
default-storage-engine=INNODB				#指定默认存储引擎
max_allowed_packet=16M						#设置数据库接收的数据包大小的最大值
server-id = 1
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_AUTO_VALUE_ON_ZERO,
NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,PIPES_AS_CONCAT,ANSI_QUOTES
Common values ​​of sql_mode are as follows:
NO_ENGINE_SUBSTITUTION
If the required storage engine is disabled or not compiled, then an error is thrown. When this value is not set, replace with the default storage engine and throw an exception
STRICT_TRANS_TABLES
In this mode, if a value cannot be inserted into a transaction table, the current operation is interrupted, and there is no restriction on non-transactional tables
NO_AUTO_CREATE_USER
Prohibit GRANT from creating users with empty passwords
NO_AUTO_VALUE_ON_ZERO
The self-increasing column in mysql can start from 0. By default, the self-increasing column starts from 1, if you insert data with a value of 0, an error will be reported
NO_ZERO_IN_DATE
Zero days and months are not allowed
NO_ZERO_DATE
mysql database does not allow inserting zero dates, inserting zero dates will throw an error instead of a warning
ERROR_FOR_DIVISION_BY_ZERO
During INSERT or UPDATE, if the data is divided by zero, an error is generated instead of a warning. By default, MySQL returns NULL when data is divided by zero
PIPES_AS_CONCAT
Treat "||" as a string concatenation operator instead of an OR operator, which is the same as the Oracle database and similar to the string concatenation function Concat
ANSI_QUOTES
When ANSI_QUOTES is enabled, double quotes cannot be used to quote a string because it is interpreted as an identifier

--basedir=/usr/local/mysql \        #指定数据库的安装目录
--datadir=/usr/local/mysql/data		#指定数据库文件的存储路径
Insert picture description here

10. Add mysqld system service

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/		#用于systemctl服务管理
systemctl daemon-reload         #刷新识别     
systemctl start mysqld.service  #开启服务
systemctl enable mysqld         #开机自启动
netstat -anpt | grep 3306       #查看端口

11. Modify the mysql login password

mysqladmin -u root -p password "666" 	#给root账号设置密码为666,提示输入的是原始密码(为空)
Insert picture description here

12. Authorize remote login

mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by '666';
#授予root用户可以在所有终端远程登录,使用的密码是666,并对所有数据库和所有表有操作权限
