1.安装Nginx服务

实验准备

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

安装依赖包

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

创建运行用户

useradd -M -s /sbin/nologin nginx

编译安装

cd /opt
tar zxvf nginx-1.12.0.tar.gz -C /opt/      #解压资源包

cd nginx-1.12.0/

./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module             #配置模块

make && make install                       #编译及编译安装

优化路径

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

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         #赋权
systemctl start nginx.service                       #开启服务
systemctl enable nginx.service                      #开机自启

2.安装 MySQL 服务

安装Mysql环境依赖包

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

创建运行用户

useradd -M -s /sbin/nologin  mysql

编译安装

cd /opt
tar zxvf mysql-boost-5.7.20.tar.gz           #将安装包放到opt目录下，并解压

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                            #配置编译模块

make && make install                        #编译及编译安装

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

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

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

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

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

修改mysql 的登录密码

mysqladmin -u root -p password "123"

授权远程登录

mysql -u root -p

3.安装配置 PHP 解析环境

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

编译安装

cd /opt
tar jxvf php-7.1.10.tar.bz2                    #解压到opt目录下

cd php-7.1.10                                  #进入解压包

./configure \
--prefix=/usr/local/php \
--with-mysql-sock=/usr/local/mysql/mysql.sock \
--with-mysqli \
--with-zlib \
--with-curl \
--with-gd \
--with-jpeg-dir \

--enable-fpm \
--enable-mbstring \
--enable-xml \
--enable-session \
--enable-ftp \
--enable-pdo \
--enable-tokenizer \
--enable-zip                                     #配置安装模块

make && make install                             #编译及编译安装

路径优化

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

调整PHP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
mysqli.default_socket = /usr/local/mysql/mysql.sock   #1170行修改
date.timezone = Asia/Shanghai                         #939行取消注释，修改

php -m                                                #验证安装的模块

cd /usr/local/php/etc/
cp  php-fpm.conf.default php-fpm.conf                 #调整进程服务配置文件

vim php-fpm.conf
pid = run/php-fpm.pid                                 #17行取消注释

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

启动php-fpm

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

cd /opt/php-7.1.10/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
systemctl restart php-fpm.service                           #重启服务

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;
            #fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include        fastcgi_params;
         }


systemctl restart nginx.service         #重启服务

验证PHP 测试页

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

<?php
phpinfo();
?>

http://192.168.88.13/index.php               #浏览器访问

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;
quit                                            #配置完成后退出

vim /usr/local/nginx/html/index.php             #替换原来的测试页内容

<?php
$link=mysqli_connect('192.168.88.13','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>

http://192.168.88.13/index.php                  #浏览器访问

?

4.部署 Discuz！社区论坛 Web 应用

解压论坛文件

cd /opt
unzip Discuz_X3.4_SC_UTF8.zip  -d /opt/dis             #解压
cd /opt/dis/dir_SC_UTF8/
cp -r upload/ /usr/local/nginx/html/bbs/               #复制到刚刚创建的bbs用户下

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://192.168.88.13/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://192.168.88.13/bbs/index.php
http://192.168.88.13/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

pm = dynamic                                         #96行fpm进程启动方式，动态的
pm.max_children=20                                   #107行fpm进程启动的最大进程数
pm.start_servers = 5                                 #112行动态方式下启动时默认开启的进程数
pm.min_spare_servers = 2                             #117行动态方式下最小空闲进程数
pm.max_spare_servers = 8                             #122行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
