1. Introduction and overview of LAMP

1.1. Overview of the LAMP platform

        The LAMP architecture is one of the mature enterprise website application modes at present. It refers to a whole system and related software that work in harmony, and can provide Dongtai web site service and its application development environment.

        LAMP is an acronym, specifically including Linux operating system, Apache web server, MySQL database server, PHP web programming language

1.2. Build the LAMP platform sequence

        When building the LAMP platform, the installation order of each component is Linux, Apache, MySQL, PHP

        Among them, the installation of Apache and MySQL does not have strict order requirements, and the installation of the PHP environment is generally put at the end, responsible for communicating with the web server and database to work together

1.3. Advantages of compiling and installing 

        1. With a large degree of freedom, the function can be customized

        2. The latest software version can be obtained in time

        3. Universally applicable to most Linux versions, easy to use all the time

1.4. The main function of each component

        linux: As the basis of the LAMP architecture, it provides an operating system for supporting Web sites, and can provide better stability and compatibility with the other three components (LAMP components also support Windows, UNIX and other platforms)

2. Application examples of LAMP architecture

2.1 Install Apache

1. Prepare the source package that needs to be installed

2. Unzip to the current directory

3. Move to the /srclib directory

4. Installation depends on the environment

 

yum -y install \
gcc \
gcc-c++ \
make \
pcre-devel \
expat-devel \
perl

5. Compile and install httpd and its modules

cd /opt/httpd-2.4.29/
./configure \
--prefix=/usr/local/httpd \
--enable-so \
--enable-rewrite \
--enable-charset-lite \
--enable-cgi

6. Specify the number of cpu cores to compile and install

 7. Optimize configuration file path

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

ln -s /usr/local/httpd/bin/* /usr/local/bin/

8. Use systemctl to facilitate service management

cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
vim /etc/init.d/httpd

 

 

 9. Start the service

10. Enter the browser to access the address of the linux ens33 network card 

 Service installed successfully!

 

2.2 Install MYSQL

1. Installation dependent environment

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

2. Create program user management

useradd -s /sbin/nologin mysql

3. Unzip the source package

tar zxvf mysql-5.7.17.tar.gz -C /opt
tar zxvf boost_1_59_0.tar.gz -C /usr/local/
mv /usr/local/boost_1_59_0 /usr/local/boost

4. mysql compile and install

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_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DWITH_BOOST=/usr/local/boost \
-DWITH_SYSTEMD=1

make && make install

Note: Deploying mysql errors is basically caused by insufficient memory, 
you can try echo 1 > /proc/sys/vm/drop_caches #Clear cache  

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 restart CMAKE, otherwise the error remains
