這裏寫目錄標題

一、LNMP架構解讀

LNMP平臺就是Linux. Ngnix. MySQL. PHP的組合架構，需要Lnux伺服器、MySal 數據庫、PHP解析壞境
Ngnix特長:高併發，低資源，處理靜態網路存取請求非常強
Apache：靜態處理和動態處理都可以做，更適合做動態處理
Nginx將動態資源請求交給PHP當中的fpm處理動態請求
PHP主組態檔：php.ini
Nginx將動態資源分配給FPM或Apache

MySQL安裝設定

1、爲了與Nginx、PHP環境保持- -致， 此處選擇採用原始碼編譯的方式安裝MySQL元件
2、MySQL部署的方法

  • 編譯安裝MySQL
  • 優化調整
  • 初始化數據庫
  • 啓動MySQL服務並設定root數據庫賬號的密碼

PHP解析環境的安裝

1、設定網頁動靜分離，解析PHP，有兩種方法可以選擇

  • 使用PHP的FPM模組
  • 將存取PHP頁面的Web請求轉交給Apache伺服器去處理
    2、較新版本的PHP已經自帶FPM模組，對PHP解析範例進行管理、優化解析效率
  • FastCGI將Http Server和動態指令碼語言分離開
  • Nginx專門處理靜態請求，轉發動態請求
  • PHP-FPM專[門解析PHP動態請求
  • 單伺服器的LNMP架構通常使用FPM方式來解析PHP

設定Nginx支援PHP環境

1、呼叫本機的php-fpm進程設定方法

  • 建立FPM組態檔php-fpm.conf,修改設定選項
    - PID檔案、執行使用者、服務進程數等
  • 啓動php-fpm進程
    2、設定Nginx支援PHP解析
  • 在Nginx的組態檔的server{ }設定段中設定將PHP的網頁請求轉給FPM模組處理
    3、PHP頁面存取測試

二、LNMP應用部署

本案例在單台伺服器上部署LNMP環境
案例架構
Linux+Nginx+MySQL+PHP

1、安裝nginx

[root@localhost ~]# cd /opt/
[root@localhost opt]# mkdir LNMP
[root@localhost opt]# cd LNMP/
[root@localhost LNMP]# rz -E     //使用xshell直接壓縮包到虛擬機器
rz waiting to receive.
[root@localhost LNMP]# ls
Discuz_X3.4_SC_UTF8.zip  mysql-boost-5.7.20.tar.gz  ncurses-5.6.tar.gz  nginx-1.12.2.tar.gz  php-7.1.10.tar.bz2
1、安裝環境依賴包
[root@localhost LNMP]# tar zxvf nginx-1.12.2.tar.gz -C /opt/
[root@localhost LNMP]# cd /opt/nginx-1.12.2/
[root@localhost nginx-1.12.2]# yum -y install gcc \
gcc-c++ \
zlib-devel \
pcre pcre-devel   //安裝編譯器和其他工具
2、建立執行使用者、組
[root@localhost nginx-1.12.2]# useradd -M -s /sbin/nologin nginx   //建立nginx管理使用者，不建立宿主目錄，禁止登陸到shell環境
[root@localhost nginx-1.12.2]# id nginx
uid=1001(nginx) gid=1001(nginx) 組=1001(nginx)
3、編譯安裝nginx
[root@localhost nginx-1.12.2]# ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module     //安裝路徑，使用者，組，統計模組功能
[root@localhost nginx-1.12.2]# make && make install
4、路徑優化
[root@localhost nginx-1.12.2]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/  //建立軟鏈接，便於管理員直接執行nginx命令來呼叫nginx主程式
[root@localhost nginx-1.12.2]# ls /usr/local/sbin/
nginx
5、檢測語法
[root@localhost nginx-1.12.2]# nginx -t
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
6、啓動、停止nginx服務
[root@localhost nginx-1.12.2]# nginx 
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      70833/nginx:
用宿主機win10去存取192.168.200.80，成功存取nginx網站
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      70833/nginx: master 
[root@localhost nginx-1.12.2]# killall -s HUP nginx     //過載nginx命令
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      70833/nginx: master 
[root@localhost nginx-1.12.2]# killall -s QUIT nginx    //關閉nginx命令
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
[root@localhost nginx-1.12.2]# nginx
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      70961/nginx: master 
[root@localhost nginx-1.12.2]# kill -9 70961    //kill殺死進程但是服務殺不死
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      70962/nginx: worker 
[root@localhost nginx-1.12.2]# pkill nginx        //pkill直接殺死進程樹
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
7、新增nginx系統服務
[root@localhost nginx-1.12.2]# vim /lib/systemd/system/nginx.service    //新增nginx服務給systemctl管理
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking              //預設進程模式
PIDFile=/usr/local/nginx/logs/nginx.pid     //進程檔案
ExecStart=/usr/local/nginx/sbin/nginx         //安裝目錄
ExecReload=/usr/bin/kill -s HUP $MAINPID   //過載目錄
ExecStop=/usr/bin/kill -s QUIT $MAINPID     //停止
PrivateTmp=ture
[Install]
WantedBy=multi-user.target      //多使用者模式
[root@localhost nginx-1.12.2]# chmod 754 /lib/systemd/system/nginx.service   //設定許可權
[root@localhost nginx-1.12.2]# systemctl start nginx
Warning: nginx.service changed on disk. Run 'systemctl daemon-reload' to reload units.      //出現警告
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
[root@localhost nginx-1.12.2]# systemctl daemon-reload      //重新載入某個服務的組態檔，如果新安裝了一個服務，歸屬於 systemctl 管理，要是新服務的服務程式組態檔生效，需重新載入。
[root@localhost nginx-1.12.2]# systemctl start nginx     //啓動服務成功
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      71619/nginx: master

3、安裝php

[root@localhost mysql]# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel curl curl-devel openssl openssl-devel    
[root@localhost mysql]# cd /opt/LNMP/
[root@localhost LNMP]# tar jxvf php-7.1.10.tar.bz2 -C /opt/
[root@localhost LNMP]# cd /opt/php-7.1.10/
[root@localhost 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

4、讓nginx支援PHP

[root@localhost php-fpm.d]# vim /usr/local/nginx/conf/nginx.conf
 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;
            include         fastcgi_params;
        }
[root@localhost php-fpm.d]# systemctl stop nginx
[root@localhost php-fpm.d]# systemctl start nginx
[root@localhost php-fpm.d]# netstat -antp | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      106079/nginx: maste
[root@localhost php-fpm.d]# cd /usr/local/nginx/
[root@localhost nginx]# ls
client_body_temp  conf  fastcgi_temp  html  logs  proxy_temp  sbin  scgi_temp  uwsgi_temp
[root@localhost nginx]# cd html/
[root@localhost html]# ls
50x.html  index.html
[root@localhost html]# mv index.html index.html.bak
[root@localhost html]# ls
50x.html  index.html.bak
[root@localhost html]# vim index.php
<?php
phpinfo()
?>

5、建立數據庫

[root@localhost html]# mysql -u root -p
Enter password: abc123
mysql> CREATE DATABASE bbs;
Query OK, 1 row affected (0.00 sec)
mysql> GRANT all ON bbs.* TO 'bbsuser'@'%' IDENTIFIED BY 'admin123';
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> GRANT all ON bbs.* TO 'bbsuser'@'localhost' IDENTIFIED BY 'admin123';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
mysql> quit
Bye

6、更改測試頁內容

[root@localhost html]# vim index.php 
<?php
$link=mysqli_connect('192.168.200.80','bbsuser','admin123');
if($link) echo "<h1>Success!!</h1>";
else echo "Fail!!";
?>
[root@localhost html]# systemctl restart nginx
用win10瀏覽器登錄192.168.200.80/index.php
