1. Overview of LAMP

The 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.

1. The role of each component

L: (Platform) Linux: As the foundation of the LAMP architecture, it provides an operating system to support Web sites, which can provide better stability and compatibility with the other three components (AMP components also support Windows, UNIX and other platforms).

A (Foreground) Apache: As the front end of the LAMP architecture, it is a powerful and stable web server program that directly provides users with website access, sending web pages, pictures and other file content.

M (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.

P (Intermediate Connection) PHP/Perl/Python: As three programming languages ​​for developing dynamic web pages, it is responsible for interpreting dynamic webpage files, communicating with web servers and database systems for collaborative work, 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.

2. Installation sequence

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.

Two, compile and install Apache httpd service

1. Turn off the firewall, and upload the software packages required to install Apache to the /opt directory

The code is as follows (example):

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
httpd-2.4.29.tar.gz
apr-1.6.2.tar.gz
apr-util-1.6.0.tar.gz
#apr组件包用于支持Apache上层应用跨平台,提供底层接口库,能有效的降低并发连接数、降低进程和减少访问堵塞。

2. The installation environment depends on the package

The code is as follows (example):

----------------------
yum -y install gcc gcc-c++ make pcre pcre-devel expat-devel perl
yum -y install \
gcc \							#C语言的编译器
gcc-c++ \						#C++的编译器
make \							#源代码编译器(源代码转换成二进制文件)
pcre \							#pcre是一个Perl函数库,包括perl 兼容的正则表达式库
pcre-devel \                    #perl的接口开发包
expat-devel \                   #用于支持网站解析HTML、XML文件

5. Create a mysql user

useradd -M -s /sbin/nologin mysql

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								#指定服务ID号

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

----------------------------------------------------------------------------------------------------------
sql_mode常用值如下:
NO_ENGINE_SUBSTITUTION
如果需要的存储引擎被禁用或未编译,那么抛出错误。不设置此值时,用默认的存储引擎替代,并抛出一个异常

STRICT_TRANS_TABLES
在该模式下,如果一个值不能插入到一个事务表中,则中断当前的操作,对非事务表不做限制

NO_AUTO_CREATE_USER
禁止GRANT创建密码为空的用户

NO_AUTO_VALUE_ON_ZERO
mysql中的自增长列可以从0开始。默认情况下自增长列是从1开始的,如果你插入值为0的数据会报错

NO_ZERO_IN_DATE
不允许日期和月份为零

NO_ZERO_DATE
mysql数据库不允许插入零日期,插入零日期会抛出错误而不是警告

ERROR_FOR_DIVISION_BY_ZERO
在INSERT或UPDATE过程中,如果数据被零除,则产生错误而非警告。默认情况下数据被零除时MySQL返回NULL

PIPES_AS_CONCAT
将"||"视为字符串的连接操作符而非或运算符,这和Oracle数据库是一样的,也和字符串的拼接函数Concat相类似

ANSI_QUOTES
启用ANSI_QUOTES后,不能用双引号来引用字符串,因为它被解释为识别符
----------------------------------------------------------------------------------------------------------
[client]
port = 3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock

[mysql]
port = 3306
default-character-set=utf8
socket = /usr/local/mysql/mysql.sock
auto-rehash

[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
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
