Compile and install Apache, mysqld, PHP

1. Overview of LAMP architecture

1. Introduction to LAMP

LAMP is an acronym for Linux operating system + Apache web server + MySQL database server + PHP (or Perl, Python) web programming language.
They are all independent programs, but combined together can be used to build a dynamic website or server open source software.

2. The role of each component
(1) Linux platform

Linux is the foundation 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 (AMP components also support platforms such as Windows and UNIX).

(2) Apache-front desk

Apache, as the front end of the LAMP architecture, is a powerful and stable web server program that directly provides users with website access, sending web pages, pictures and other file content.

(3) MySQL-background

As the back end of the LAMP architecture, MySQL is a popular open source relational database system.
In applications such as corporate websites and business systems, various account information, product information, customer information, business data, etc. can be stored in the MySQL database, and other programs can query and change this information through SQL statements.

(4) PHP/Perl/Python—Intermediate connection

PHP/Perl/Python: As three programming languages ​​for developing dynamic web pages, it is responsible for interpreting dynamic webpage files, communicating with web servers and database systems to work together, and providing a development and operating environment for web applications.

Among them, PHP is a widely used open source multi-purpose scripting language, which can be embedded in HTML, and is especially suitable for Web application development. (This chapter is written in PHP language)

(5) The sequence of building the LAMP platform

When building the LAMP platform, the order of installation of each component is: Linux→Apache→MySQL→PHP. Among them, there is no strict order for the installation of Apache and MySQL. The installation of the PHP environment is generally placed at the end of the installation, responsible for communicating with the Web server and the database system to work together.

Two, compile and install Apache httpd

1.关闭防火墙,将安装Apache所需软件包传到/opt目录下
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组件包用于支持Apache上层应用跨平台,提供底层接口库,能有效的降低并发连接数、降低进程和减少访问堵塞。

2.安装环境依赖包

5.优化配置文件路径,并把httpd服务的可执行程序文件放入路径环境变量的目录中便于系统识别
ln -s /usr/local/httpd/conf/httpd.conf /etc/
ln -s /usr/local/httpd/bin/* /usr/local/bin/

6.添加httpd系统服务
方法一:
cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd		#用于service服务管理
chmod +x /etc/init.d/httpd
vi /etc/init.d/httpd
#!/bin/bash												#在第一行前插入新行,添加此三行内容
# chkconfig: 35 85 21									#35级别自动运行  第85个启动 第21个关闭
# description: Apache is a World Wide Web server

chkconfig --add httpd     		#将httpd服务加入到service管理器

systemctl start httpd.service
或
service httpd start

方法二:
vim /lib/systemd/system/httpd.service
[Unit]
Description=The Apache HTTP Server						#描述
After=network.target									#描述服务类别
[Service]
Type=forking											#后台运行方式
PIDFile=/usr/local/httpd/logs/httpd.pid					#PID文件位置

Listen 192.198.19.88:80
--197行--取消注释,修改
ServerName www.feng.com:80

--221行--默认首页存放路径
DocumentRoot "/usr/local/httpd/htdocs"
--255行--默认首页文件名设置
DirectoryIndex index.html

httpd -t  或 apachectl -t			#检查配置文件的配置项是否有误
cat /usr/local/httpd/htdocs/index.html
systemctl restart httpd.service

8.浏览器访问验证
netstat -anpt | grep 80
echo "192.168.19.88 www.feng.com" >> /etc/hosts

http://192.168.19.88
http://www.feng.com

Three, compile and install mysqld

1.将安装mysql 所需软件包传到/opt目录下

tar zxvf boost_1_59_0.tar.gz

cd /opt
mv boost_1_59_0 /usr/local/boost		#重命名

cd /opt/mysql-5.7.17/
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \		#指定mysql的安装路径
-DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock \ #指定mysql进程监听套接字文件(数据库连接文件)的存储路径
-DSYSCONFDIR=/etc \                             #指定配置文件的存储路径
-DSYSTEMD_PID_DIR=/usr/local/mysql \            #指定进程文件的存储路径

-DWITH_SYSTEMD=1								#生成便于systemctl管理的文件

存储引擎选项:
MYISAM,MERGE,MEMORY,和CSV引擎是默认编译到服务器中,并不需要明确地安装。
静态编译一个存储引擎到服务器,使用-DWITH_engine_STORAGE_ENGINE= 1
可用的存储引擎值有:ARCHIVE, BLACKHOLE, EXAMPLE, FEDERATED, INNOBASE (InnoDB), PARTITION (partitioning support), 和PERFSCHEMA (Performance Schema)
----------------------------------------------------------------------------------------------------------

注意:如果在CMAKE的过程中有报错,当报错解决后,需要把源码目录中的CMakeCache.txt文件删除,然后再重新CMAKE,否则错误依旧

4.编译及安装
make && make install

5.创建mysql用户
useradd -M -s /sbin/nologin  mysql

6.修改mysql 配置文件
vim /etc/my.cnf								#删除原配置项,再重新添加下面内容
[client]									#客户端设置
port = 3306
socket = /usr/local/mysql/mysql.sock			

[mysql]										#服务端设置
port = 3306
socket = /usr/local/mysql/mysql.sock
auto-rehash									#开启自动补全功能

[mysqld]									#服务全局设置
user = mysql       							#设置管理用户
basedir=/usr/local/mysql					#指定数据库的安装目录
datadir=/usr/local/mysql/data				#指定数据库文件的存储路径
port = 3306									#指定端口
character-set-server=utf8					#设置服务器字符集编码格式为utf8
pid-file = /usr/local/mysql/mysqld.pid		#指定pid 进程文件路径
socket=/usr/local/mysql/mysql.sock			#指定数据库连接文件
bind-address = 0.0.0.0						#设置监听地址,0.0.0.0代表允许所有,如允许多个IP需空格隔开
skip-name-resolve							#禁用DNS解析
max_connections=2048						#设置mysql的最大连接数
default-storage-engine=INNODB				#指定默认存储引擎
max_allowed_packet=16M						#设置数据库接收的数据包大小的最大值
server-id = 1								#指定服务ID号

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_mode常用值如下:
NO_ENGINE_SUBSTITUTION
如果需要的存储引擎被禁用或未编译,那么抛出错误。不设置此值时,用默认的存储引擎替代,并抛出一个异常

STRICT_TRANS_TABLES
在该模式下,如果一个值不能插入到一个事务表中,则中断当前的操作,对非事务表不做限制

NO_AUTO_CREATE_USER
禁止GRANT创建密码为空的用户

NO_AUTO_VALUE_ON_ZERO
mysql中的自增长列可以从0开始。默认情况下自增长列是从1开始的,如果你插入值为0的数据会报错

NO_ZERO_IN_DATE
不允许日期和月份为零

NO_ZERO_DATE
mysql数据库不允许插入零日期,插入零日期会抛出错误而不是警告

ERROR_FOR_DIVISION_BY_ZERO
在INSERT或UPDATE过程中,如果数据被零除,则产生错误而非警告。默认情况下数据被零除时MySQL返回NULL

PIPES_AS_CONCAT
将"||"视为字符串的连接操作符而非或运算符,这和Oracle数据库是一样的,也和字符串的拼接函数Concat相类似

ANSI_QUOTES
启用ANSI_QUOTES后,不能用双引号来引用字符串,因为它被解释为识别符
----------------------------------------------------------------------------------------------------------
[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

7.更改mysql安装目录和配置文件的属主属组
chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf

8.设置路径环境变量
echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile	
source /etc/profile

9.初始化数据库
cd /usr/local/mysql/bin/
./mysqld \
--initialize-insecure \				#生成初始化密码为空
--user=mysql \                      #指定管理用户
--basedir=/usr/local/mysql \        #指定数据库的安装目录
--datadir=/usr/local/mysql/data		#指定数据库文件的存储路径
----------------------------------------------------------------------------------------------------------
./mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data

10.添加mysqld系统服务
cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/		#用于systemctl服务管理
systemctl daemon-reload         #刷新识别     
systemctl start mysqld.service  #开启服务
systemctl enable mysqld         #开机自启动
netstat -anpt | grep 3306       #查看端口

11.修改mysql 的登录密码
mysqladmin -u root -p password "abc123" 	#给root账号设置密码为abc123,提示输入的是原始密码(为空)

12.授权远程登录
mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by 'abc123';
#授予root用户可以在所有终端远程登录,使用的密码是abc123,并对所有数据库和所有表有操作权限

show databases;			#查看当前已有的数据库
