One 、LAMP Introduction and Overview

1.1LAMP Platform Overview

• LAMP Architecture is one of the mature enterprise website application modes , It refers to a whole system and related software working together , Can provide dynamic web Site service and its application development environment

• LAMP It's an abbreviation , Specific include Linux operating system ,Apache Web server ,MySQL database server ,PHP（ or perl,Python） Web programming language

2.2 structure LAMP Platform sequence

• In the build LAMP Platform time , The installation sequence of each component is Linux,Apache,MySQL,PHP

• among Apache and MySQL There is no strict sequence requirement for the installation of , and PHP The installation of the environment is usually at the end of the day , Responsible for communication web Servers and database systems to work together

2.3 Advantages of compiling and installing

1、 With a large degree of freedom , Features can be customized
2、 Timely access to the latest software version
3、 Generally applicable to most Linux edition , Easy to use all the time

2.4 The main function of each component

1.( platform )Linux： As LAMP The foundation of Architecture , Provide for support Web The operating system of the site , Can provide better stability with the other three components , Compatibility (AMP Components also support Windows、UNIX Such as platform ) .

2.( The front desk )Apache： As LAMP The front end of the architecture , It's a powerful , Stable Web Server program , The server provides website access directly to users , Send web page , Pictures, etc .

3.( backstage )MySQL： As LAMP The back end of the architecture , Is a popular open source relational database system . On the corporate website 、 Business systems and other applications , All kinds of account information 、 Product information , Customer information 、 Business data can be stored in MySQL database , Other programs can be done through SQL Statement to query , Change this information .

4.( The middle link )PHP/Perl/Python： As three programming languages for developing dynamic web pages , Responsible for interpreting dynamic web files , Responsible for communication Web Servers and database systems to work together , And provide Web Application development and running environment . among PHP Is a widely used open source multi-purpose scripting language , It can be embedded in HTML in , Especially suitable for Web application development

2.5LAMP Architecture description

• working process ：

1. When the client requests static resources ,web The server will return the static resources directly to the client

2. When the client requests a dynamic resource ,httpd Of php The module performs the corresponding dynamic resource operation , If this process also needs the data of the database as the operation parameters ,php Will connect mysql Calculate after obtaining data , The result of the operation is converted to static resources web The server returns to the client

notes ： Static resources are drawn for better understanding , Normal is in apache Running in

Two , Deploy LAMP

1. Compilation and installation Apache httpd

1.1 Turn off firewall , Will deploy LAMP All required software packages are transferred to /opt Under the table of contents

systemctl stop firewalld	
systemctl disable firewalld
setenforce 0

[[email protected] ~]# cd /opt
[[email protected] opt]# ls
apr-1.6.2.tar.gz       Discuz_X3.4_SC_UTF8.zip  php-7.1.24.tar.gz
apr-util-1.6.0.tar.gz  httpd-2.4.29.tar.bz2    
boost_1_59_0.tar.gz    mysql-5.7.17.tar.gz
#apr Component packages are used to support Apache The upper application is cross platform , Provide the underlying interface library , Can effectively reduce the number of concurrent connections 、 Reduce process and access congestion 

1.2 Install environment dependency package

yum -y install \
gcc \							#C Compiler of language 
gcc-c++ \						#C++ The compiler 
make \							# Source code compiler （ Convert source code to binary file ）
pcre \							#pcre It's a Perl function library , Include perl  Compatible regular expression library 
pcre-devel \                    #perl Interface development package for 
expat-devel \                   # Used to support website parsing HTML、XML file 
perl                            #perl Language compiler 

notes ： Previously installed httpd Service suggestions: delete the software package first , To avoid port conflicts 、 Procedure conflict and so on

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

1.3 Configuration 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

cd /opt/httpd-2.4.29/
./configure \
--prefix=/usr/local/httpd \		# Specify the  httpd  The installation path of the service program 
--enable-so \					# Enable dynamic load module support , send  httpd  With the ability to further expand functions 
--enable-rewrite \				# Enable Web address rewriting , For website optimization 、 Security chain and directory migration maintenance 
--enable-charset-lite \			# Start character set support , To support pages encoded with various character sets 
--enable-cgi					# Enable CGI（ Universal gateway interface ） Scripting support , It is convenient for the external expansion of the website and the application access ability 

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

1.4 Compile and install

make && make install

1.5 Optimize the configuration file path , And put httpd The executable program file of the service is put into the directory of the path environment variable to facilitate system identification

ln -s /usr/local/httpd/conf/httpd.conf /etc/  ## Master profile 
ln -s /usr/local/httpd/bin/* /usr/local/bin/   ## Startup file 

1.6 add to httpd system service

• Method 1 ： Apply to centos6、7; But it's less efficient

# Easy service management 
cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
vim /etc/init.d/httpd

# chkconfig: 35 85 21  //35 Level auto run    The first 85 Start up   The first 21 Closed 
# description: Apache is a World Wide Web server
---》wq

chkconfig --add httpd // take httpd Add to system manager 

[[email protected] httpd-2.4.29]# systemctl start httpd
# You can use service perhaps systemctl Conduct management 

• Method 2 ： Used in centos7 More efficient

vim /lib/systemd/system/httpd.service

[Unit]

systemctl start httpd.service
systemctl enable httpd.service

1.7 modify httpd Service profile

vim /etc/httpd.conf
--52 That's ok -- modify 
Listen 192.198.113.128:80
--197 That's ok -- uncomment , modify 
ServerName 192.168.113.128:80

--221 That's ok -- Default home page storage path 
DocumentRoot "/usr/local/httpd/htdocs"
--255 That's ok -- Default home page file name setting 
DirectoryIndex index.html

httpd -t   or  apachectl -t			# Check if the configuration item in the configuration file is wrong 
Syntax OK

cat /usr/local/httpd/htdocs/index.html
<html><body><h1>It works!</h1></body></html>

systemctl restart httpd.service

1.8 Browser access verification

netstat -anpt | grep 80

echo "192.168.113.128 www.benet.com" >> /usr/local/httpd/htdocs/index.html

2. Compilation and installation mysql service

2.1 Will install mysql The required software package is transferred to /opt Under the table of contents

boost_1_59_0.tar.gz		# Support c++ The runtime 

2.2 Install environment dependency package

yum -y install \
gcc \
gcc-c++ \
ncurses \				# Dynamic library of graphic interaction function under character terminal 
ncurses-devel \			#ncurses Development kit 
bison \					# parsers 
cmake					#mysql Need to use cmake Compilation and installation 
   
yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake

2.3 Configuration software module

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

cd /opt/mysql-5.7.17/
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \		# Appoint mysql Installation path for 
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ # Appoint mysql The process listens to socket files （ Database connection file ） Storage path for 
-DSYSCONFDIR=/etc \                             # Specify the storage path of the configuration file 
-DSYSTEMD_PID_DIR=/usr/local/mysql \            # Specifies the storage path of the process file 
-DDEFAULT_CHARSET=utf8  \                       # Specifies the default character set encoding , Such as  utf8
-DDEFAULT_COLLATION=utf8_general_ci \			# Specifies the character set collation rules to be used by default 
-DWITH_EXTRA_CHARSETS=all \						# Specify support for other character set encoding 
-DWITH_INNOBASE_STORAGE_ENGINE=1 \              # install INNOBASE Storage engine 
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \               # install ARCHIVE Storage engine  
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \             # install BLACKHOLE Storage engine  
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \        	# install FEDERATED Storage engine  
-DMYSQL_DATADIR=/usr/local/mysql/data \     	# Specify the storage path of the database file 
-DWITH_BOOST=/usr/local/boost \          		# Appoint boost The path of , If you use mysql-boost Integration package installation is -DWITH_BOOST=boost
-DWITH_SYSTEMD=1								# Generation facilitates systemctl Administrative document 
   
 Storage engine options ：
MYISAM,MERGE,MEMORY, and CSV The engine is compiled to the server by default , There is no need to explicitly install .
 Statically compile a storage engine to the server , Use -DWITH_engine_STORAGE_ENGINE= 1
 The available storage engine values are ：ARCHIVE, BLACKHOLE, EXAMPLE, FEDERATED, INNOBASE (InnoDB), PARTITION (partitioning support),  and PERFSCHEMA (Performance Schema)

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
   
 Be careful ： If in CMAKE There are errors in the process of , When the error is resolved , Need to put the source directory of CMakeCache.txt File deletion , And then... Again CMAKE, Otherwise, the mistake remains 

2.4 Compile and install

make -j 4 && make install

2.5 establish mysql user

useradd -M -s /sbin/nologin  mysql

2.6 modify mysql The configuration file

vim /etc/my.cnf								# Delete the original configuration item , Add the following again 
[client]									# Client side Settings 
port = 3306
socket=/usr/local/mysql/mysql.sock			
   
[mysqld]									# Service global settings 
user = mysql       							# Set up administrative users 
basedir=/usr/local/mysql					# Specify the installation directory of the database 
datadir=/usr/local/mysql/data				# Specify the storage path of the database file 
port = 3306									# Designated port 
character-set-server=utf8					# Set the server character set encoding format to utf8
pid-file = /usr/local/mysql/mysqld.pid		# Appoint pid  Process file path 
socket=/usr/local/mysql/mysql.sock			# Specify the database connection file 
bind-address = 0.0.0.0						# Set listening address ,0.0.0.0 The representative allows all , If multiple IP It needs to be separated by spaces 
skip-name-resolve							# Ban DNS analysis 
max_connections=2048						# Set up mysql Is the maximum number of connections 
default-storage-engine=INNODB				# Specify the default storage engine 
max_allowed_packet=16M						# Set the maximum packet size received by the database 
server-id = 1								# Designated Services ID Number 
   
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

[client]									
port = 3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock	

[mysql]									
port = 3306
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock
auto-rehash

[mysqld]
user = mysql 
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306	
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_connections=2048
default-storage-engine=INNODB
max_allowed_packet=16M
server-id = 1
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

Words explain ：

sql_mode Common values are as follows :
NO_ENGINE_SUBSTITUTION
If the required storage engine is disabled or not compiled , Then throw an error . When this value is not set , Replace... With the default storage engine , And throw an exception

STRICT_TRANS_TABLES
In this mode , If a value cannot be inserted into a transaction table , Then interrupt the current operation , No restrictions on non transaction tables

NO_AUTO_CREATE_USER
prohibit GRANT Create a user with a blank password

NO_AUTO_VALUE_ON_ZERO
mysql The self growing columns in can be derived from 0 Start . By default, self growing columns are generated from 1 At the beginning , If you insert a value of 0 The data will report an error

NO_ZERO_IN_DATE
Zero days and months are not allowed

NO_ZERO_DATE
mysql Database is not allowed to insert zero date , Inserting a zero date throws an error instead of a warning

ERROR_FOR_DIVISION_BY_ZERO
stay INSERT or UPDATE In the process , If the data is divided by zero , It's a mistake, not a warning . By default, when data is divided by zero MySQL return NULL

PIPES_AS_CONCAT
take "||" Treat as the concatenation operator of a string, not as the or operator , This sum Oracle The database is the same , And string concatenation function Concat Similar

ANSI_QUOTES
Enable ANSI_QUOTES after , You can't use double quotes to refer to strings , Because it's interpreted as an identifier

2.7 change mysql The primary group of the installation directory and configuration files

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

2.8 Set the environment variable , Affirming / Declare mysql The command is easy for the system to recognize

echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
source /etc/profile

2.9 Initialize database

cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \				# Generate initialization password is empty 
--user=mysql \                      # Specify the administrative user 
--basedir=/usr/local/mysql \        # Specify the installation directory of the database 
--datadir=/usr/local/mysql/data		# Specify the storage path of the database file 

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

2.10 add to mysqld system service

cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/	# be used for systemctl Service management 
systemctl daemon-reload			  # Refresh recognition      
systemctl start mysqld.service    # Opening service 
systemctl enable mysqld           # Boot up 
netstat -anpt | grep 3306         # Check the port 

2.11 to root Account setup password

mysqladmin -u root -p password "000000" 
————》 Directly enter 

2.12 Grant remote login

mysql -u root -p
    
grant all privileges on *.* to 'root'@'%' identified by '123123';
# grant root Users can log in remotely at all terminals , The password used is 123123, And all databases and all tables have operation permissions
