LAMP introduction and overview
(1) Overview of LAMP platform
LAMP architecture is one of the mature enterprise website application modes at present. It refers to a whole system and related software working together, which can provide dynamic web site services and its application development environment
LAMP is an abbreviation, including Linux operating system, Apache Web server, MySQL database server, PHP (or perl, Python) web programming language
(2) . sequence of building LAMP platform
When building the LAMP platform, the installation sequence of each component is Linux, Apache, MySQL and PHP
There is no strict sequence requirement for the installation of Apache and MySQL, while the installation of PHP environment is generally put at the end, which is responsible for communicating the web server and database system to work together
(3) Advantages of compilation and installation
1. It has a large degree of freedom and can be customized
2. The latest software version can be obtained in time
3. It is generally applicable to most Linux versions and is easy to use all the time
(4) Main functions of components
(platform) Linux: as the basis of LAMP architecture, it provides an operating system 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).
(front desk) Apache: 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.
(background) MySQL: 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.
(intermediate connection) PHP/Perl/Python: 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.
Environmental preparation
Turn off firewall and selinux
systemctl stop firewal1d.service setenforce 0
1, Install Apache
Transfer the software package required to install Apache into the / opt directory
cd /opt/
(I sent the software package to the resource)
Unzip package
tar xf apr-1.6.2.tar.gz tar xf apr-util-1.6.0.tar.gz tar jxf httpd-2.4.29.tar.bz2 ls
Move the apr package to the installation directory and switch to the httpd-2.4.29 directory
mv apr-1.6.2 httpd-2.4.29/srclib/apr mv apr-util-1.6.0 httpd-2.4.29/srclib/apr-util cd httpd-2.4.29/
Check it out
Install environment dependent packages
yum -y install \ gcc \ #C language compiler gcc-c++ \ #C + + compiler make \ #Source code compiler (source code to binary) pcre-devel \ #perl interface development package expat-devel \ #Used to support website parsing HTML and XML files perl #perl compiler
Compile and install
./configure \ --prefix=/usr/local/httpd \ #Specify the installation path of the httpd service program --enable-so \ #Enable dynamic loading core 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 enhance the access ability of external extended applications of the website
The results are shown in the figure below
make && make install -j8 (Do not compile with a number larger than the number of kernels)
The results are shown in the figure below
cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd vim /etc/init.d/httpd # Chkconfig: 35 85 21 / / 35 level automatic operation 85th startup 21st shutdown # description: Apache is a World Wide Web server
Add httpd to the SERVICE manager and modify the configuration file
chkconfig --add httpd
Change line 52 to your own IP address
vim /usr/local/httpd/conf/httpd.conf Listen 192.168.241.134:80
Be sure to delete the # number in line 197
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/
Then enter to see if there is an error
httpd -t
Start the service and view
service httpd start ss -ntap |grep "80"
After success, you can enter your own IP address in the browser, as shown in the following figure
The above completes the Apache installation
2, Install MYSQL
Install dependent packages first
yum install -y ncurses-devel autoconf cmake
Check it out
cd mysql-5.6.26
Then compile the installation
cmake \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DDEFAULT_CHARSET=utf8 \ #Specifies the character set encoding used by default, such as utf-8 -DDEFAULT_COLLATION=utf8_general_ci \ #Specifies the default character set collation rule to use -DEXTRA_CHARSETS=all \ #Specifies that other character set encodings are supported -DSYSCONFIDIR=/etc \ #/There is a default configuration / etc/my.cnf in the / etc / MySQL -- > system -DMYSQL_DATADIR=/home/mysql/ \ #data file -DMYSQL_UNIX_ADDR=/home/mysql/mysql.sock #Specify the communication file to connect to the database (it will be generated when starting the database)
This time is quite long
make && make install -j8
then
cp support-files/my-default.cnf /etc/my.cnf cp support-files/mysql.server /etc/init.d/mysqld
Modify the permissions
chmod 755 /etc/init.d/mysqld
Startup and self start
chkconfig --add /etc/init.d/mysqld chkconfig mysqld --level 35 on
Put all the commands in / etc/profile
echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile source /etc/profile echo $PATH
Change a subordinate primary group
useradd -s /sbin/nologin mysql chown -R mysql:mysql /usr/local/mysql/
Initialize it
/usr/local/mysql/scripts/mysql_install_db \ --user=mysql \ --ldata=/var/lib/mysql \ --basedir=/usr/local/mysql \ --datadir=/home/mysql
Modify profile
vim /etc/init.d/mysqld basedir=/usr/local/mysql datadir=/home/mysql
Then start to check whether it is successful
service mysqld start ss -ntap |grep "3306"
//Set password for root account
mysqladmin -u root -p password "abc123"
Enter the following code to enter mysql, and then enter the password "abc123" set above
mysql -u root -p
In this way, you have logged in and mysql has been successfully installed
3, Install PHP
yum -y install \ gd \ #Library of image processing libpng \ #png format picture library libpng-devel \ pcre \ #The PCRE library supports regular expressions pcre-devel \ #PCRE devel is the development library required for secondary development using PCRE, and it is also required for compilation and installation libxml2-devel \ #Parsing xml markup language library libjpeg-devel #jpeg format picture library cd /opt/ ls
Unzip php and take a look
tar xjvf php-5.6.11.tar.bz2 cd php-5.6.11 ls
compile
./configure \ --prefix=/usr/local/php5 \ --with-gd \ --with-zlib \ --with-apxs2=/usr/local/httpd/bin/apxs \ --with-mysql=/usr/local/mysql \ --with-config-file-path=/usr/local/php5 \ --enable-mbstring
make && make install -j8
Optimization puts PHP executable program files into the directory of path environment variables for system identification
ln -s /usr/local/php5/bin/* /usr/local/bin/
Modify the Apache configuration file to make Apache support PHP (as shown below)
vim /etc/httpd.conf
Create and edit php page files
vim /usr/local/httpd/htdocs/index.php <?php phpinfo(); ?>
Restart service
service httpd stop service httpd start
Test on Web“ http://192.168.241.134/index.php ”(own IP address)
As shown in the figure, it is built successfully
4, Build a forum
Open database
mysql -u root -p
Then create a database bbs
mysql> CREATE DATABASE bbs; //Create a database// mysql> GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123'; //Grant permissions to all tables in the bbs database to bbsuser and set the password. / / all access sources / channels mysql>flush privileges; //Refresh database//
Check it out
show databases;
The creation is successful
Then unzip it
unzip /opt/Discuz_X2.5_SC_UTF8.zip -d /opt/dis
cd /opt/dis cp -r upload/ /usr/local/httpd/htdocs/bbs cd /usr/local/httpd/htdocs/bbs
Change the permissions
chown -R daemon ./config chown -R daemon ./data chown -R daemon ./uc_client chown -R daemon ./uc_server/data
Enter website
http:///192.168.241.134/bbs
The following interface will succeed, and then install step by step
