LNMP架构搭建Discuz论坛(实战!)

系统运维

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

    Sharename       Type      Comment

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
[root@nginx nginx-1.12.2]# setenforce 0
[root@nginx nginx-1.12.2]# 

8.用宿主机浏览器访问nginx服务

编译安装MySQL
1.安装编译mysql所需环境包

[root@localhost system]# yum install ncurses ncurses-devel bison cmake -y
.........//省略安装过程
[root@localhost system]# 

2.添加一个mysql用户

[root@localhost system]# useradd -s /sbin/nologin mysql
[root@localhost system]#

3.将mysql源码包解压到“/opt/”目录下

[root@localhost system]# cd /mnt/tools/LNMP/
[root@localhost LNMP]# ls

> -DWITH_BOOST=boost \\\\     //底层运行库
> -DWITH_SYSTEMD=1      //主从参数

5.编译安装MySQL服务

[root@localhost mysql-5.7.20]# make && make install
...........//省略编译过程
[root@localhost mysql-5.7.20]#

6.更改数据库目录属主、属组

[root@localhost mysql-5.7.20]# chown -R mysql:mysql /usr/local/mysql/
[root@localhost mysql-5.7.20]# 

7.修改配置文件

[root@localhost mysql-5.7.20]# vim /etc/my.cnf
[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
[root@localhost mysql-5.7.20]# source /etc/profile    //重新加载配置文件
[root@localhost mysql-5.7.20]#

9.初始化数据库

[root@localhost mysql-5.7.20]# cd /usr/local/mysql/
[root@localhost mysql]# ls
bin  COPYING  COPYING-test  docs  include  lib  man  mysql-test  README  README-test  share  support-files  usr

[root@localhost mysql]# bin/mysqld \\\\
> --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 
New 
Confirm new 
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
