linux下lnmp构建内网论坛,LNMP架构搭建Discuz论坛（实战！）

什么是LNMP架构

LNMP平台就是Linux、Ngnix、 MySQL、 PHP的组合架构，需要Linux服务器、MySQL数据库、PHP解析环境

MySQL安装配置

为了与Nginx、PHP环境保持一致，此处选择采用源代码编译的方式安装MySQL组件

MySQL部署的方法

编译安装MySQL

优化调整

初始化数据库

启动mysq|服务并设置root数据库账号的密码

PHP解析环境的安装

配置网页动静分离，解析PHP,有两种方法可以选择

使用PHP的FPM模块

将访问PHP页面的Web请求转交给Apache服务器去处理

较新版本的PHP已经自带FPM模块，用来对PHP解析实例进行管理、优化解析效率

FastCGI将Http Server和动态脚本语言分离开

Nginx专门处理静态请求，转发动态请求

PHP_FPM专门 ]解析PHP动态请求

单服务器的LNMP架构通常使用FPM的方式来解析PHP，本次也使用FPM模块处理动态请求。

PHP编译安装步骤

编译安装PHP

编译选项时添加"--enable-fpm” 以启用此模块

安装后的调整，主要是配置文件的建立与相应命令工具的路径优化

安装ZendGuardloader (提高PHP解析效率)，并进行加载配置

实验准备

1.将宿主机上的工具包共享出去

2.通过Samba服务将工具包挂载到Linux系统

[root@localhost ~]# mkdir /mnt/tools

[root@localhost ~]# smbclient -L //192.168.100.50/

Enter SAMBA\root's password:

OS=[Windows 10 Enterprise LTSC 2019 17763] Server=[Windows 10 Enterprise LTSC 2019 6.3]

Password for root@//192.168.100.50/tools:

[root@localhost ~]#

编译安装Nginx服务

1.将nginx服务源码包解压到“/opt/”目录

[root@localhost ~]# cd /mnt/tools/

[root@localhost tools]# ls

awstats-7.6.tar.gz extundelete-0.2.4.tar.bz2 forbid.png jdk-8u191-windows-x64.zip LAMP-C7 picture.jpg

cronolog-1.6.2-14.el7.x86_64.rpm fiddler.exe intellijideahahau2018.rar john-1.8.0.tar.gz LNMP

[root@localhost tools]# cd LNMP/

[root@localhost LNMP]# ls

Discuz_X3.4_SC_UTF8.zip mysql-boost-5.7.20.tar.gz nginx-1.12.2.tar.gz php-7.1.10.tar.bz2 php-7.1.20.tar.gz

[root@localhost LNMP]# tar zxvf nginx-1.12.2.tar.gz -C /opt/

...............//省略解压过程

[root@localhost LNMP]#

2.安装编译所需工具包

[root@localhost ~]# yum install gcc gcc-c++ pcre-devel zlib-devel -y

...........//省略安装过程

[root@localhost ~]#

3.切换到nginx服务源码包目录，创建一个nginx用户

[root@localhost LNMP]# cd /opt/

[root@localhost opt]# ls

nginx-1.12.2 rh

[root@localhost opt]# cd nginx-1.12.2/

[root@localhost nginx-1.12.2]# ls

auto CHANGES CHANGES.ru conf configure contrib html LICENSE man README src

[root@localhost nginx-1.12.2]#

[root@localhost nginx-1.12.2]# useradd -M -s /sbin/nologin nginx //-M 不创建家目录

[root@localhost nginx-1.12.2]# id nginx

uid=1001(nginx) gid=1001(nginx) 组=1001(nginx)

[root@localhost nginx-1.12.2]#

4.配置nginx服务

[root@localhost nginx-1.12.2]# ./configure \

> --prefix=/usr/local/nginx \ //安装路径

> --user=nginx \ //属主

> --group=nginx \ //属组

> --with-http_stub_status_module //启用统计模块

5.编译安装nginx服务

[root@localhost nginx-1.12.2]# make && make install

..........//省略过程

[root@localhost nginx-1.12.2]#

6.在易于系统识别的目录下，建立nginx服务命令的软链接

[root@localhost nginx-1.12.2]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/ //建立软链接

[root@localhost nginx-1.12.2]# nginx -t //配置文件测试

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@localhost nginx-1.12.2]#

7.制作nginx服务管理脚本(任选一种即可)

脚本一：通过“systemctl”命令管理

[root@localhost nginx-1.12.2]# cd /lib/systemd/system

[root@localhost system]# vim 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=/usr/bin/kill -s HUP $MAINPID

ExecStop=/usr/bin/kill -s QUIT $MAINPID

PrivateTmp=true

[Install]

WantedBy=multi-user.target

[root@localhost system]# chmod 754 nginx.service //添加执行权限

[root@localhost system]# systemctl start nginx.service //开启服务

[root@localhost system]# netstat -ntap | grep 80 //查看tcp80端口

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 52924/nginx: master

[root@localhost system]#

[root@localhost system]# systemctl stop firewalld.service //关闭防火墙

[root@localhost system]# setenforce 0

[root@localhost system]#

脚本二：通过“service”命令管理

[root@nginx nginx-1.12.2]# vim /etc/init.d/nginx

#!/bin/bash

# chkconfig: - 99 20

# description: Nginx Service Control Script

PROG="/usr/local/nginx/sbin/nginx"

PIDF="/usr/local/nginx/logs/nginx.pid"

case "$1" in

start)

$PROG

;;

stop)

kill -s QUIT $(cat $PIDF)

;;

restart)

$0 stop

$0 start

;;

reload)

kill -s HUP $(cat $PIDF)

;;

*)

echo "Usage: $0 {start|stop|restart|reload}"

exit 1

esac

exit 0

[root@nginx nginx-1.12.2]#

[root@nginx nginx-1.12.2]# chmod +x /etc/init.d/nginx //添加执行权限

[root@nginx nginx-1.12.2]# chkconfig --add nginx //添加让service能识别nginx服务

[root@nginx nginx-1.12.2]#

[root@nginx nginx-1.12.2]# service nginx start //开启服务

[root@nginx nginx-1.12.2]# netstat -ntap | grep 80 //查看tcp80端口

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 58696/nginx: master

[root@nginx nginx-1.12.2]#

[root@nginx nginx-1.12.2]# systemctl stop firewalld.service //关闭防火墙

[client] //客户端

port = 3306

default-character-set=utf8

socket = /usr/local/mysql/mysql.sock

[mysql] //客户端

port = 3306

default-character-set=utf8

socket = /usr/local/mysql/mysql.sock

[mysqld] //服务器

user = mysql //用户

basedir = /usr/local/mysql //设置mysql的安装目录

datadir = /usr/local/mysql/data //设置mysql数据库的数据的存放目录

port = 3306 //设置3306端口

character_set_server=utf8 //中文字符集

pid-file = /usr/local/mysql/mysqld.pid //pid文件路径

socket = /usr/local/mysql/mysql.sock //sock文件路径

server-id = 1 //主从参数

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

//支持模块

8.将mysql相关命令添加本地环境配置中

[root@localhost mysql-5.7.20]# echo 'PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH' >> /etc/profile

//将MySQL写到本地环境配置中

[root@localhost mysql-5.7.20]# echo 'export PATH' >> /etc/profile //设置全局环境配置

> --initialize-insecure \ //初始化

> --user=mysql \ //用户

> --basedir=/usr/local/mysql \ //安装目录

> --datadir=/usr/local/mysql/data //数据库数据文件目录

10.将MySQL服务配置文件复制到/usr/lib/systemd/system/下便于使用systemctl管理

[root@localhost mysql]# cp usr/lib/systemd/system/mysqld.service /lib/systemd/system/

//复制

[root@localhost mysql]# systemctl start mysqld.service //启动服务

[root@localhost mysql]# netstat -ntap | grep 3306 //查看tcp3306端口

tcp6 0 0 :::3306 :::* LISTEN 78684/mysqld

[root@localhost mysql]#

11.配置MySQL密码

[root@localhost mysql]# mysqladmin -u root -p password

Enter password:

New password:

Confirm new password:

Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.

[root@localhost mysql]#

12.尝试登陆MySQL数据库

[root@localhost mysql]# mysql -u root -p

Enter password:
