LLinux deploys LAMP service to build Discuz forum

Introduction to LAMP

LAMP architecture is one of the current mature enterprise website application modes. It refers to a set of systems and related operations that work together to provide dynamic website services and application development environments.
LAMP: Linux operating system, Apache web server, MySQL database server, PHP web programming language.

Component role

Linux: The foundation of the LAMP architecture, and the operating system that provides the support site.
Apache: The front end of LAMP is a powerful and stable web server program that directly provides users with website access, sending web pages, pictures and other file content.
MySQL: The back end of LAMP is a popular open source relational database system. In applications such as enterprises and business systems, various account information can be stored in the MySQL database.
PHP/Perl/Pythom: As three programming languages ​​for developing dynamic web pages. Responsible for interpreting dynamic web files, and for communicating with web servers and database systems to work together.

Install Apache service

1. Turn off the firewall, and upload the required software packages to install Apache to the /opt directory
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 component package is used to support cross-platform Apache upper-level applications, provide the underlying interface library, can be effective Reduce the number of concurrent connections, reduce processes and reduce access congestion.

2. The installation environment depends on the package
yum -y install gcc gcc-c++ make pcre pcre-devel expat-devel perl

3. Configure the software module
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

./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi

4. Compile and install
make -j2 && make install ##Turn on 2 cores to compile and 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 for the system to recognize
ln -s /usr/local/httpd/conf/httpd.conf /etc/
ln -s /usr /local/httpd/bin/* /usr/local/bin/

6. Add httpd system service
Method one:
cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd #for service 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 #35 level automatically runs the 85th start and the 21st close
#description: Apache is a World Wide Web server

chkconfig --add httpd #Add httpd service to service manager

systemctl start httpd.service

7. Modify the httpd service configuration file
vim /etc/httpd.conf-Line
52-Modify
Listen 192.198.226.40:80-Line
197-Uncomment, modify
ServerName www.jmi.com:80

–Line 221 – The default home page storage path
DocumentRoot "/usr/local/httpd/htdocs"
– Line 255 – The default home page file name setting
DirectoryIndex index.html

httpd -t or apachectl -t #Check whether the configuration items of the configuration file are wrong
cat /usr/local/httpd/htdocs/index.html
systemctl restart httpd.service

8. Browser access verification
netstat -anpt | grep 80
echo "192.168.226.40 www.jmi.com" >> /etc/hosts

http://192.168.226.40
http://www.jmi.com
Note: The modification of the configuration file requires a certain amount of time to compile.
The content in the homepage file appears on the visited webpage and it is installed.

MySQL installation

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

2. The installation environment depends on the package
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

Note: If the content of the home page does not change after changing the home page file, first clear the browser cache and check the firewall. If it doesn’t work, check after the change. Is there a problem with the configuration file? Pay attention to the command to restart the httpd service. Is httpd really restarted? If everything is correct, check the log file. If you can't find the error, rebuild it in time. If you enter the wrong password when installing the forum, delete the uploaded site update package and reinstall it.
