The construction of LAMP architecture realizes the Forum web page

1. What is LAMP

1.1 introduction to lamp

LAMP architecture is one of the mature enterprise website application modes at present. It refers to a complete set of systems and related software working together, which can provide static and dynamic web site services and its application development environment. Specifically, it includes Linux operating system, Apache Web server, MySQL database server, PHP (or Perl, Python) web programming language.

1.2 description of all components

Linux (platform): as the basis of LAMP architecture, it provides 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).
Apache (foreground): as the front end of 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 contents.
**MySQL (background): * * as the back end of LAMP architecture, it is a popular open source relational database system. In enterprise websites, business systems and other applications, various account information, product information, customer information and business data can be stored in MySQL database. Other programs can query and change these information through SQL statements.
**PHP/Perl/Python (intermediate connection): as three programming languages for developing dynamic Web pages, it is responsible for interpreting dynamic Web page files, communicating the Web server and database system to work together, and providing the development and running environment of Web applications** PHP is a widely used open source multi-purpose scripting language, which can be embedded in HTML, especially suitable for Web application development.

The installation sequence is Linux, Apache, MySQL and PHP in turn. The installation of PHP environment is generally put at the end, and is responsible for communicating the Web server and database system to work together.

2. Installing Apache services

2.1 turn off the firewall

2.2 installing dependent packages

yum -y install \
gcc \							#C language compiler
gcc-c++ \						#C + + compiler
make \							#Source code compiler (source code to binary file)
pcre \							#pcre is a perl function library, including perl compatible regular expression library
pcre-devel \                    #perl interface development package
expat-devel \                   #It is used to support the website to parse HTML and XML files
perl                            #perl compiler

2.3 transfer the software packages required to install Apache to the / opt directory

3. Install environment dependent packages

gcc 				#C language compiler
gcc-c++ 			#C + + compiler
make 				#Source code compiler (source code to binary file)
pcre 				#pcre is a perl function library, including perl compatible regular expression library
pcre-devel          #perl interface development package
expat-devel         #It is used to support the website to parse HTML and XML files
perl                #perl compiler

4. Unzip three compressed packages

5. Configuration software module

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 \		#Specify the path where the httpd service program will be installed
--enable-so \					#Enable dynamic loading module support to enable httpd to further expand its functions
--enable-rewrite \				#Enable the web address rewriting function for website optimization, anti-theft chain and directory migration maintenance
--enable-charset-lite \			#Start character set support to support pages encoded with various character sets
--enable-cgi					#Enable CGI (general Gateway Interface) script program support to facilitate the external expansion of application access capability of the website

6. Compilation and installation

make							#make -j 2 means to open 2 cores and compile at the same time
make install

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

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

8. Add httpd system service

① Method 1:

cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd		#Used for service management
chmod +x /etc/init.d/httpd
vi /etc/init.d/httpd
#!/bin/bash												#Insert a new line before the first line and add these three lines
# chkconfig: 35 85 21									#Level 35 automatic operation, 85th start, 21st close
# description: Apache is a World Wide Web server
chkconfig --add httpd     		#Add httpd service to service manager
systemctl start httpd.service
 or
service httpd start

② Method 2:

vim /lib/systemd/system/httpd.service
[Unit]
Description=The Apache HTTP Server						#describe
After=network.target									#Describe service category
[Service]
Type=forking											#Background operation mode
PIDFile=/usr/local/httpd/logs/httpd.pid					#PID file location
ExecStart=/usr/local/bin/apachectl $OPTIONS				#Start service
ExecReload=/bin/kill -HUP $MAINPID						#According to PID overload configuration
[Install]
WantedBy=multi-user.target
systemctl start httpd.service
systemctl enable httpd.service

9. Modify / etc / httpd Conf service configuration file

10. Browser access verification

11. Use domain name access

3, Manually compile mysql database

1. Transfer the software package required to install mysql to the / opt directory

2. Install environment dependent packages

yum -y install \
gcc \
gcc-c++ \
ncurses \				#Dynamic library of graphic interactive function under character terminal
ncurses-devel \			#ncurses development kit
bison \					#Parser
cmake					#mysql needs to be compiled and installed with cmake

3. Configuration 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		#rename
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

Storage engine options:
- MYISAM, MERGE, MEMORY, and CSV engines are compiled into the server by default and do not need to be explicitly installed.
- Statically compile a storage engine to the server, using - DWITH_engine_STORAGE_ENGINE= 1
- Available storage engine values are: archive, Blackhole, expand, federated, innobase (InnoDB), partition (partitioning support), and PERFSCHEMA (Performance Schema)
be careful:
- If an error is reported in the process of CMAKE, after the error is solved, you need to put cmakecache in the source directory Txt file is deleted, and then CMAKE is again. Otherwise, the error remains the same

4. Compilation and installation

make && make install

5. Create mysql user

useradd -M -s /sbin/nologin  mysql

6. Modify mysql configuration file

vim /etc/my.cnf								#Delete the original configuration item and add the following content again
