4. Modify the mysql configuration file

vim /etc/my.cnf
[client]
port = 3306
socket=/usr/local/mysql/mysql.sock

[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

5. Change the owner group of the mysql installation directory and configuration file

chown -R mysql:mysql /usr/local/mysql/
chown mysql:mysql /etc/my.cnf
Insert picture description here

echo 'export PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile	
source /etc/profile
Insert picture description here

7. Initialize the database

cd /usr/local/mysql/bin/
mysqld \
--initialize-insecure \
--user=mysql \
--basedir=/usr/local/mysql \
--datadir=/usr/local/mysql/data
Insert picture description here

8. Add mysqld system service

cp usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/
systemctl daemon-reload
systemctl start mysqld.service
systemctl enable mysqld

Three, install and configure PHP parsing environment

1. The installation environment depends on the package

yum -y install gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel
Insert picture description here

2. Compile and install

cd /opt
tar xjvf php-7.1.10.tar.bz2

cd php-7.1.10
./configure \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-freetype-dir \
--with-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \

3. Path optimization

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

4. Adjust the PHP configuration file

php有三个配置文件: 
php.ini			主配置文件  
php-fpm.conf	进程服务配置文件 
www.conf		扩展配置文件

调整主配置文件:
cp /opt/php-7.1.10/php.ini-development /usr/local/php/php.ini	
vim /usr/local/php7/php.ini
--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939行--取消注释,修改
date.timezone = Asia/Shanghai

php -m 					#验证安装的模块

调整进程服务配置文件:
cd /usr/local/php/etc/
cp  php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
--17行--去掉";"注释
pid = run/php-fpm.pid

调整扩展配置文件:
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

5. Start php-fpm

/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
netstat -anpt | grep 9000

#PHP-FPM (FastCGI Process Manager: FastCGI Process Manager) is a PHPFastCGI manager. Since the Nginx server cannot handle dynamic pages, Nginx needs to pass dynamic requests to the php-fpm process for analysis.

6. Configure Nginx to support PHP parsing

vi /usr/local/nginx/conf/nginx.conf
--65行--取消注释,修改
location ~ \.php$ {
	root           html;
	fastcgi_pass   127.0.0.1:9000;
	fastcgi_index  index.php;
	fastcgi_param  SCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;	#将/scripts修改为nginx的工作目录
	include        fastcgi_params;
}

systemctl restart nginx.service

7. Verify the PHP test page

vim /usr/local/nginx/html/index.php

<?php phpinfo(); ?>

8. Verify that the database is working properly

mysql -u root -p
CREATE DATABASE bbs;
GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123';
GRANT all ON bbs.* TO 'bbsuser'@'localhost' IDENTIFIED BY 'admin123';
flush privileges;

vim /usr/local/nginx/html/index.php      		#替换原来的测试页内容
<?php
$link=mysqli_connect('192.168.195.128','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>
