LNMP的架构

一。【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

二。【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 \                                                  #因为是2合1包软件包解压完boost目录直接在当前目录中

-DWITH_SYSTEMD=1

make -j 2 && 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

grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘abc123‘;

三。【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;

#将/scripts修改为nginx的工作目录

fastcgi_paramSCRIPT_FILENAME  /usr/local/nginx/html$fastcgi_script_name;

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

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://192.168.80.10/bbs/install/index.php

数据库服务器：localhost              ##本地架设就用localhost，如果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

五。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，为了在不断开服务的情况下进行重载配置文件

netstat -anpt | grep 9000

ps -elf | grep php-fpm
