7 The verification results

Two 、 install MySQL service

1 install MySQL Environment dependent packages

yum -y install \
ncurses \
ncurses-devel \
bison \
cmake

2 Create a running user

useradd -M -s /sbin/nologin  mysql

 Compile and install 
make -j4 && make install

4 modify MySQL The 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

5 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

6 Set the path environment variable

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

7 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

8 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

9 modify MySQL The login code of

mysqladmin -u root -p password "123456"  to root Set the password to 123456, The prompt is the original password （ It's empty ）

10 Authorize remote login

mysql -u root -p
grant all privileges on *.* to 'root'@'%' identified by '123456';
# grant root Users can log in remotely at all terminals , The password used is 123456, And all databases and all tables have operation permissions 
 
show databases;			# View the existing database

3、 ... and 、 Installation configuration PHP Analyze the environment

1 Install environment dependency package

 install GD Kuhe GD Library correlator , Used to process and generate images 
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

2 Compilation and installation

cd /opt
tar jxvf 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-openssl \
--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip

make -j2 && make install

3 Path optimization

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

4 adjustment PHP The configuration file

4.1 Adjust the main profile

cp /opt/php-7.1.24/php.ini-development /usr/local/php/lib/php.ini	
vim /usr/local/php/lib/php.ini
--1170 That's ok -- modify 
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939 That's ok -- uncomment , modify 
date.timezone = Asia/Shanghai

php -m 					# Verify the installed module

4.2 Adjust the process configuration file

cd /usr/local/php/etc/
cp  php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
--17 That's ok -- Get rid of ";" notes 
pid = run/php-fpm.pid

4.3 Adjust the extended profile

cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

5 start-up 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 ) It's a PHPFastCGI Manager , because Nginx The server can't handle dynamic pages , Need by Nginx Give the dynamic request to php-fpm Process .

6 To configure Nginx Support PHP analysis

vim /usr/local/nginx/conf/nginx.conf
--65 That's ok -- uncomment , modify 
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;	# take  /scripts  It is amended as follows nginx Working directory of 
   #fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;  #$document_root  On behalf of the current request root The value specified in the instruction 
	include        fastcgi_params;
}

systemctl restart nginx.service

Restart the service

7 verification PHP Test page

vim /usr/local/nginx/html/index.php
<?php
phpinfo();
?>

Restart the service ：systemctl restart nginx

Browser access

8 Verify that the database is working properly

mysql -u root -p
# Create a database 
CREATE DATABASE bbs;
# hold bbs The permissions of all tables in the database are granted to bbsuser, And set the password 123456
GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY '123456';   # Refresh database 
flush privileges;    # See what databases are 
show databases;

vim /usr/local/nginx/html/index.php      		# Replace the content of the original test page 
<?php
$link=mysqli_connect('192.168.152.11','bbsuser','123456');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

9 Browser access

Four 、 Deploy Discuz Forum

1 Unzip the forum package

unzip Discuz_X3.4_SC_UTF8.zip  -d /opt/dis

2 Upload site update package

cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/

3 Adjust the permissions of forum Directory

cd /usr/local/nginx/html/bbs/
chown -R nginx ./config/
chown -R nginx ./data/
