一、LNMP架构解读
LNMP平台就是Linux. Ngnix. MySQL. PHP的组合架构，需要Lnux服务器、MySal 数据库、PHP解析坏境
Ngnix特长:高并发，低资源，处理静态网络访问请求非常强
Apache：静态处理和动态处理都可以做，更适合做动态处理
Nginx将动态资源请求交给PHP当中的fpm处理动态请求
PHP主配置文件：php.ini
Nginx将动态资源分配给FPM或Apache
MySQL安装配置
1、为了与Nginx、PHP环境保持- -致， 此处选择采用源代码编译的方式安装MySQL组件
2、MySQL部署的方法
- 编译安装MySQL
- 优化调整
- 初始化数据库
- 启动MySQL服务并设置root数据库账号的密码
PHP解析环境的安装
1、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
2、较新版本的PHP已经自带FPM模块，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方式来解析PHP
配置Nginx支持PHP环境
1、调用本机的php-fpm进程配置方法
- 建立FPM配置文件php-fpm.conf,修改配置选项
- PID文件、运行用户、服务进程数等 - 启动php-fpm进程
2、配置Nginx支持PHP解析 - 在Nginx的配置文件的server{ }配置段中设置将PHP的网页请求转给FPM模块处理
3、PHP页面访问测试
二、LNMP应用部署
本案例在单台服务器上部署LNMP环境
案例架构
Linux+Nginx+MySQL+PHP
1、安装nginx
[root@localhost ~]# cd /opt/
[root@localhost opt]# mkdir LNMP
[root@localhost opt]# cd LNMP/
[root@localhost LNMP]# rz -E //使用xshell直接压缩包到虚拟机
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、安装环境依赖包
[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 //安装编译器和其他工具
2、创建运行用户、组
[root@localhost nginx-1.12.2]# useradd -M -s /sbin/nologin nginx //创建nginx管理用户，不建立宿主目录，禁止登陆到shell环境
[root@localhost nginx-1.12.2]# id nginx
uid=1001(nginx) gid=1001(nginx) 组=1001(nginx)
3、编译安装nginx
[root@localhost nginx-1.12.2]# ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module //安装路径，用户，组，统计模块功能
[root@localhost nginx-1.12.2]# make && make install
4、路径优化
[root@localhost nginx-1.12.2]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/ //创建软链接，便于管理员直接执行nginx命令来调用nginx主程序
[root@localhost nginx-1.12.2]# ls /usr/local/sbin/
nginx
5、检测语法
[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、启动、停止nginx服务
[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:
用宿主机win10去访问192.168.200.80，成功访问nginx网站
[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 //重载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 //关闭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杀死进程但是服务杀不死
[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直接杀死进程树
[root@localhost nginx-1.12.2]# netstat -antp | grep nginx
7、添加nginx系统服务
[root@localhost nginx-1.12.2]# vim /lib/systemd/system/nginx.service //添加nginx服务给systemctl管理
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking //默认进程模式
PIDFile=/usr/local/nginx/logs/nginx.pid //进程文件
ExecStart=/usr/local/nginx/sbin/nginx //安装目录
ExecReload=/usr/bin/kill -s HUP $MAINPID //重载目录
ExecStop=/usr/bin/kill -s QUIT $MAINPID //停止
PrivateTmp=ture
[Install]
WantedBy=multi-user.target //多用户模式
[root@localhost nginx-1.12.2]# chmod 754 /lib/systemd/system/nginx.service //配置权限
[root@localhost nginx-1.12.2]# systemctl start nginx
Warning: nginx.service changed on disk. Run 'systemctl daemon-reload' to reload units. //出现警告
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 //重新加载某个服务的配置文件，如果新安装了一个服务，归属于 systemctl 管理，要是新服务的服务程序配置文件生效，需重新加载。
[root@localhost nginx-1.12.2]# systemctl start nginx //启动服务成功
[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
2、安装MYSQL
[root@localhost nginx-1.12.2]# cd /opt/LNMP/
[root@localhost LNMP]# ls

[root@localhost LNMP]# tar zxvf mysql-boost-5.7.20.tar.gz -C /opt/
[root@localhost LNMP]# cd /opt/

44、让nginx支持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;

?>5、创建数据库
[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
Bye6、更改测试页内容
[root@localhost html]# vim index.php
$link=mysqli_connect('192.168.200.80','bbsuser','admin123');
if($link) echo "Success!!
";
else echo "Fail!!";
?>
[root@localhost html]# systemctl restart nginx
用win10浏览器登录192.168.200.80/index.php
