LAMP architecture and forum installation

LAMP architecture

1. Familiar with LAMP architecture

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, specifically including Linux operating system, Apache web server, MySQL database server, PHP (or Perl, Python) web programming language

1. Linux platform

Provide the operating system used 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)

2. Apache front desk

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

3. Mysql background

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

4. PHP intermediate connection

Responsible for interpreting dynamic web 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.

Two, compile and install Apache httpd service

1. Turn off the firewall, and upload the required software packages to the /opt directory to
install the package :
httpd-2.4.29.tar.gz
apr-1.6.2.tar.gz
apr-util-1.6.0.tar.gz

systemctl stop firewalld
systemctl disable firewalld #开机不启动防火墙
setenforce 0

2. Installation environment dependent packages

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
perl                            #perl语言编译器

3. Configure the software module

解压
cd /opt/
tar zxvf apr-1.6.2.tar.gz
tar zxvf apr-util-1.6.0.tar.gz
tar jxvf httpd-2.4.29.tar.bz2

mv apr-1.6.2 /opt/httpd-2.4.29/srclib/apr
mv apr-util-1.6.0 /opt/httpd-2.4.29/srclib/apr-util

cd /opt/httpd-2.4.29/
./configure \
--prefix=/usr/local/httpd \		#指定将 httpd 服务程序的安装路径
--enable-so \					#启用动态加载模块支持,使 httpd 具备进一步扩展功能的能力
--enable-rewrite \				#启用网页地址重写功能,用于网站优化、防盗链及目录迁移维护
--enable-charset-lite \			#启动字符集支持,以便支持使用各种字符集编码的页面
--enable-cgi					#启用CGI(通用网关接口)脚本程序支持,便于网站的外部扩展应用访问能力
./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi

4. Compile and install

make -j2  表示开2核同时进行编译  &&  make install

5. Optimize the configuration file path, and put the executable program file of the httpd service into the directory of the path environment variable to facilitate system identification

ln -s /usr/local/httpd/conf/httpd.conf /etc/
ln -s /usr/local/httpd/bin/* /usr/local/bin/

6. Add httpd system service

vim /lib/systemd/system/httpd.service

将下面的复制进去

[Unit]
Description=The Apache HTTP Server					   
After=network.target								
[Service]
Type=forking											
PIDFile=/usr/local/httpd/logs/httpd.pid					
ExecStart=/usr/local/bin/apachectl $OPTIONS			
ExecReload=/bin/kill -HUP $MAINPID					
[Install]
WantedBy=multi-user.target

systemctl start httpd.service
systemctl enable httpd.service

7. Modify the httpd service configuration file

vim /etc/httpd.conf
--52行--修改
Listen 192.198.80.10:80
--197行--取消注释,修改
ServerName www.csdn.com:80
--221行--默认首页存放路径
DocumentRoot "/usr/local/httpd/htdocs"
--255行--默认首页文件名设置
DirectoryIndex index.html

httpd -t  或 apachectl -t			#检查配置文件的配置项是否有误

cat /usr/local/httpd/htdocs/index.html
systemctl restart httpd.service

8. Browser access verification

netstat -anpt | grep 80
echo "192.168.80.10 www.csdn.com" >> /etc/hosts
 
http://192.168.80.10
http://www.csdn.com

Three, compile and install mysqld service

1. Transfer the software packages required to install mysql to the /opt directory
mysql-5.7.17.tar.gz
boost_1_59_0.tar.gz #Support C++ runtime library

2. The installation environment depends on the package

yum -y install \
gcc \
gcc-c++ \
ncurses \				#字符终端下图形互动功能的动态库
ncurses-devel \			#ncurses开发包
bison \					#语法分析器
cmake					#mysql需要用cmake编译安装

yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake

3. Configure the software module

tar zxvf mysql-5.7.17.tar.gz
tar zxvf boost_1_59_0.tar.gz

cd /opt
mv boost_1_59_0 /usr/local/boost		#重命名

cd /opt/mysql-5.7.17/

cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \
-DSYSCONFDIR=/etc \
-DSYSTEMD_PID_DIR=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8  \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=/usr/local/boost \
-DWITH_SYSTEMD=1

注意:如果在CMAKE的过程中有报错,当报错解决后,需要把源码目录中的CMakeCache.txt文件删除,然后再重新CMAKE,否则错误依旧

4. Compile and install

make  -j2 && make install  #大约需要20分钟左右,看个人配置虚拟机的内核数

5. Create 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

7. Change the owner group of the mysql installation directory and configuration file

chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf

8. Set the path environment variable

echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile	
source /etc/profile

9. Initialize the database

cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data

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 "123456" 	#给root账号设置密码为123456,提示输入的是原始密码(为空)

12. Authorize remote login

mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
#授予root用户可以在所有终端远程登录,使用的密码是abc123,并对所有数据库和所有表有操作权限

show databases;			#查看当前已有的数据库

Four, compile and install the PHP parsing environment

1. Transfer the software packages needed to install PHP to the /opt directory

6. Optimize the PHP executable program file to be placed in the directory of the path environment variable for easy system identification

ln -s /usr/local/php7/bin/* /usr/local/bin/
php -m 			#查看PHP 加载了哪些模块

7. Modify the configuration file of the httpd service to allow Apache to support PHP

vim /etc/httpd.conf 
--393行--插入以下内容
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
--255行--修改首页文件名设置
