2023-12-11 10:48:09

【安装 Nginx 服务】

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

1、安装依赖包

yum -y install pcre-devel zlib-devel gcc gcc-c++ make

2、创建运行用户

useradd -M -s /sbin/nologin nginx

3、编译安装

cd /opt
tar zxvf nginx-1.12.0.tar.gz -C /opt/

cd nginx-1.12.0/
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module

make && make install

4、优化路径

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

5、添加 Nginx 系统服务
vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

【安装 MySQL 服务】
1、安装Mysql环境依赖包

yum -y install ncurses ncurses-devel bison cmake

2、创建运行用户

useradd -M -s /sbin/nologin mysql

3、编译安装

cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz

cd /opt/mysql-5.7.20/
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=boost -DWITH_SYSTEMD=1

make && make install

4、修改mysql 配置文件
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、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

6、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

7、初始化数据库

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

8、添加mysqld系统服务

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

9、修改mysql 的登录密码

mysqladmin -u root -p password "abc123"

10、授权远程登录
mysql -u root -p

【安装配置 PHP 解析环境】
1、安装环境依赖包

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、编译安装
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-freetype-dir --with-openssl --enable-fpm --enable-mbstring --enable-xml --enable-session --enable-ftp --enable-pdo --enable-tokenizer --enable-zip

make && make install

3、路径优化

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

4、调整PHP配置文件
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/lib/php.ini
vim /usr/local/php/lib/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、启动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 进程管理器)是一个 PHPFastCGI 管理器，由于Nginx服务器不能处理动态页面，需要由 Nginx 把动态请求交给 php-fpm 进程进行解析。

cd /opt/php-7.1.10/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service

systemctl restart php-fpm.service

6、配置 Nginx 支持 PHP 解析

vim /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、验证PHP 测试页

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

浏览器访问
http://192.168.80.10/index.php

8、验证数据库工作是否正常
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
$link=mysqli_connect(‘192.168.80.10‘,‘bbsuser‘,‘admin123‘);
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

浏览器访问
http://192.168.80.10/index.php

【部署 Discuz！社区论坛 Web 应用】

cd /opt
unzip Discuz_X3.4_SC_UTF8.zip -d /opt/dis
cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/

调整论坛目录的权限：

cd /usr/local/nginx/html/bbs/
chown -R nginx ./config/
chown -R nginx ./data/
chown -R nginx ./uc_client/
chown -R nginx ./uc_server/
或
chmod -R 777 ./config/
chmod -R 777 ./data/
chmod -R 777 ./uc_client/
chmod -R 777 ./uc_server/

论坛页面访问
http://192.168.80.10/bbs/install/index.php
----------------------------------------------------------------------------------------------------------
数据库服务器：localhost ###本地架设就用localhost，如何不是在在本机上就要填写IP地址和端口号
数据库名字：bbs
数据库用户名：bbsuser
数据库密码：admin123
管理员账号:admin
管理员密码:admin123
----------------------------------------------------------------------------------------------------------
访问论坛页面：
http://192.168.80.10/bbs/index.php
http://192.168.80.10/bbs/admin.php

----------------fpm参数优化-------------------

vim /usr/local/php/etc/php-fpm.conf
pid = run/php-fpm.pid

vim /usr/local/php/etc/php-fpm.d/www.conf
--96行--
pm = dynamic #fpm进程启动方式，动态的
--107行--
pm.max_children=20 #fpm进程启动的最大进程数
--112行--
pm.start_servers = 5 #动态方式下启动时默认开启的进程数，在最小和最大之间
--117行--
pm.min_spare_servers = 2 #动态方式下最小空闲进程数
--122行--
pm.max_spare_servers = 8 #动态方式下最大空闲进程数

kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` #重启php-fpm
netstat -anpt | grep 9000
ps -elf | grep php-fpm
