一、安装 Nginx 服务

systemctl stop firewalld

systemctl disable firewalld

setenforce 0

1.1 安装依赖包

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

1.2 创建运行用户

useradd -M -s /sbin/nologin nginx

1.3 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 -j 4&& make install

#-j4代表四核，根据自己的虚机选择相应的核数，加快编译速度

1.4 优化路径

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

1.5 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

二、安装 MySQL 服务

2.1 安装Mysql环境依赖包

yum -y install \

ncurses \

ncurses-devel \

bison \

cmake

2.2 创建运行用户

useradd -M -s /sbin/nologin  mysql

2.3 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 \

-DWITH_EMBEDDED_SERVER=OFF

make -j 4 && make install

2.4 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

2.5 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

2.6 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

2.7 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

2.8 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

2.9 修改mysql 的登录密码

mysqladmin -u root -p password “000000”

2.10 授权远程登录

mysql -u root -p


能够登录说明安装成功了

三、安装配置 PHP 解析环境

3.1 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

3.2 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 -j4 && make install

3.3 路径优化

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

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

3.4 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

3.5 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

3.6 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

#fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;  #$document_root 代表当前请求在root指令中指定的值

include        fastcgi_params;

}

systemctl restart nginx.service

3.7 验证PHP 测试页

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

<?php

phpinfo();

?>

浏览器访问

http://192.168.109.132/index.php

3.8 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

四、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://192.168.109.132/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://192.168.109.132/bbs/index.php

http://192.168.109.132/bbs/admin.php

五、fpm参数优化

Nginx的PHP解析功能实现如果是交由FPM处理的，为了提高PHP的处理速度，可对FPM模块进行参数的调整

根据服务器的内存与服务负载，调整FPM模块参数

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
