Source code compilation and installation LAMP

preface

The lamp architecture based on apache is one of the mature enterprise website application modes and one of the highest market share in the market. Learning to deploy a basic lamp architecture can be the start of our in-depth study and understanding of the more complex architecture.

1, LAMP overview

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 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.

(1) Function of each component

50: (platform) L inux: 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).

A: (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.

M: (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.

P: (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.

(2) Installation sequence of components

When building the LAMP platform, the installation sequence of each component is Linux, Apache, MySQL and PHP. Apache and MySQL are not installed in strict order. 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) Data flow direction

2, Compile and install apache httpd service

(1) Close the firewall and upload the required software packages for installing apache to the / OPT directory

[root@youzi bbs]# systemctl stop firewalld
[root@youzi bbs]# systemctl disable firewalld
[root@youzi bbs]# setenforce 0


#apr component package is used to support Apache upper application cross platform and provide lower interface library, which can effectively reduce the number of concurrent connections, processes and access congestion.

(2) Install environment dependent packages

[root@youzi opt]# yum install gcc gcc-c++ make pcre pcre-devel expat-devel perl -y

(3) Configuration software module

[root@youzi opt]# tar xf apr-1.6.2.tar.gz
[root@youzi opt]# tar xf apr-util-1.6.0.tar.gz
[root@youzi opt]# tar xf httpd-2.4.29.tar.bz2

[root@youzi opt]# mv apr-1.6.2 httpd-2.4.29/srclib/apr
[root@youzi opt]# mv apr-util-1.6.0 httpd-2.4.29/srclib/apr-util

[root@youzi httpd-2.4.29]# ./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi


(4) Compilation and installation

make							#make -j n means that n cores are compiled at the same time (n is a number)
make install

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

[root@youzi httpd-2.4.29]# ln -s /usr/local/httpd/conf/httpd.conf /etc/
[root@youzi httpd-2.4.29]# ln -s /usr/local/httpd/bin/* /usr/local/bin/

(6) Add httpd system service

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

[root@youzi httpd-2.4.29]# systemctl start httpd.service
[root@youzi httpd-2.4.29]# systemctl enable httpd.service

(7) Modify httpd service configuration file

vim /etc/httpd.conf
--52 that 's ok--modify
Listen 192.198.184.10:80
--197 that 's ok--Uncomment, modify
ServerName www.youzi.com: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 whether the configuration items of the configuration file are incorrect
cat /usr/local/httpd/htdocs/index.html
systemctl restart httpd.service





(8) Access browser authentication

echo "192.168.184.10 www.lic.com" >> /etc/hosts   #Append the ip and domain name to the / etc/hosts file
/etc/hosts The file is a host mapping file that will IP File corresponding to the host

3, Compile and install mysqld service

(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

[root@youzi opt]# yum -y install gcc gcc-c++ ncurses ncurses-devel bison cmake

(3) Configuration software module

[root@youzi opt]# tar zxf mysql-5.7.17.tar.gz
[root@youzi opt]# tar zxf boost_1_59_0.tar.gz

[root@youzi opt]# mv boost_1_59_0 /usr/local/boost
[root@youzi opt]# cd /opt/mysql-5.7.17/
[root@youzi 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, EXAMPLE, FEDERATED, INNOBASE (InnoDB), PARTITION (partitioning support), and PERFSCHEMA (Performance Schema)

Note: 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

[root@youzi mysql-5.7.17]# make -j 3 && make install

(5) Create mysql user

[root@youzi mysql-5.7.17]# useradd -M -s /sbin/nologin mysql

(6) Modify profile

[root@youzi mysql-5.7.17]# vim /etc/my.cnf								#Delete the original configuration item and add the following content again
[client]									#Client settings
port = 3306
socket=/usr/local/mysql/mysql.sock			

[mysqld]									#Service global settings
user = mysql       							#Set management 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
port = 3306									#Specify port
character-set-server=utf8					#Set the encoding format of the server character set to utf8
pid-file = /usr/local/mysql/mysqld.pid		#Specify pid process file path
socket=/usr/local/mysql/mysql.sock			#Specify database connection file
bind-address = 0.0.0.0						#Set the listening address. 0.0.0.0 means that all IP addresses are allowed. If multiple IP addresses are allowed, they should be separated by spaces
skip-name-resolve							#Disable DNS resolution
max_connections=2048						#Set the maximum number of mysql 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								#Specify service 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

sql_ The common values of mode are as follows:
NO_ENGINE_SUBSTITUTION
If the required storage engine is disabled or not compiled, an error is thrown. When this value is not set, the default storage engine is used instead and an exception is thrown

STRICT_TRANS_TABLES
In this mode, if a value cannot be inserted into a transaction table, the current operation will be interrupted and the non transaction table will not be restricted

NO_AUTO_CREATE_USER
GRANT is prohibited from creating users with blank passwords

NO_AUTO_VALUE_ON_ZERO
The self growing column in mysql can start from 0. By default, the self growth column starts from 1. If you insert data with a value of 0, an error will be reported

NO_ZERO_IN_DATE
Zero date and month are not allowed

NO_ZERO_DATE
mysql database is not allowed to insert zero date. Inserting zero date will throw an error instead of a warning

ERROR_FOR_DIVISION_BY_ZERO
During INSERT or UPDATE, if the data is divided by zero, an error is generated instead of a warning. By default, MySQL returns NULL when the data is divided by zero

PIPES_AS_CONCAT
Treating "|" as a concatenation operator of a string rather than an or operator is the same as in Oracle database and is similar to the Concat function of a string

ANSI_QUOTES
Enable ANSI_ After quotes, the string cannot be referenced in double quotation marks because it is interpreted as an identifier

(7) Change the primary group of mysql installation directory and configuration file

[root@youzi bin]# chown -R mysql:mysql /usr/local/mysql/
[root@youzi bin]# chown mysql:mysql /etc/my.cnf

(8) Environment variable setting

./mysqld \
--initialize-insecure \				#Generation initialization password is null
--user=mysql \                      #Specify 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

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

(10) Add mysqld system service

[root@youzi bin]# cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/		#For systemctl service management
[root@youzi bin]# systemctl daemon-reload         #Refresh recognition     
[root@youzi bin]# systemctl start mysqld.service  #Open service
[root@youzi bin]# systemctl enable mysqld         #Power on self start
[root@youzi bin]# netstat -anpt | grep 3306       #View port

(11) Modify the login password of mysql

mysqladmin -u root -p password "123456" 	#Set the password to abc123 for the root account, and the prompt is the original password (empty)

(12) Authorize remote login

mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
#The root user is authorized to log in remotely at all terminals with the password abc123, and has operation authority on all databases and tables

show databases;			#View existing databases
