LNMP工作原理：
客户端发送请求，Nginx负责接收，如果是静态资源（html、js、css、png等）则自己处理并返回给客户！
Nginx接收的是动态请求（.php请求文件）则转发到PHP服务端，交由PHP服务端处理！
PHP接收处理Nginx转发过来动态请求，并返回给Nginx服务端！
如果请求中包含了 SQL 语句，PHP则会连接mysql服务器，进行增删改查等操作，最终将处理完的数据返回给Nginx，再由Nginx返回给客户端请求！
也就是说，在lnmp分布式部署时候，只需要配置Nginx+PHP，PHP+Mysql即可！
最后安装phpMyAdmin来验证效果！
1、如果phpMyAdmin能成功运行，说明lnmp分布式部署是成功的！
2、phpMyAdmin安装在实际工作中也是经常能碰到的！
环境准备：
| Nginx | 192.168.140.130 |
| PHP | 192.168.140.132 |
| Mysql | 192.168.140.129 |
一、Nginx安装
之前文章已经说过怎么源码安装nginx，这边不再详细记录，具体安装请参考这篇文章 --->常用的Web服务源码编译安装
二、安装MySQL
这边主要使用基于glib（半成品包，可以指定配置文件、数据文件路径）包来安装mysql；
对源码编译安装mysql感兴趣的读者，可以参考这篇文章 ---> Mysql5.7源码编译安装
环境清理：
#查看是否自带的mysql rpm -qa | grep mysql rpm -qa | grep mariadb mariadb-libs-5.5.68-1.el7.x86_64mariadb-5.5.68-1.el7.x86_64 #删除mariadb yum remove mariadb rpm -e mariadb-libs-5.5.68-1.el7.x86_64 --nodeps rm -rf /etc/my.cnf
下载参考链接：https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.39.tar.gz
创建运行mysql的用户
useradd -r -s /sbin/nologin mysql
创建数据目录、日志目录并授权
#创建数据目录 [root@localhost src]# mkdir -p /data/mysql57/data #创建日志目录 [root@localhost src]# mkdir -p /data/mysql57/log #更改目录所有者 [root@localhost src]# chown -R mysql.mysql /data
mysql5.7解压编译安装
#解压mysql5.7 [root@localhost local]# tar zxvf src/mysql-5.7.39-linux-glibc2.12-x86_64.tar.gz #重命名安装目录并进入该目录 [root@localhost local]# mv mysql-5.7.39-linux-glibc2.12-x86_64/ mysql5.7 [root@localhost local]# cd mysql5.7/ [root@localhost mysql5.7]
在安装目录下创建配置文件my.cnf
vim my.cnf [client] port=3306 socket=/tmp/mysql57.sock [mysqld] socket=/tmp/mysql57.sock character-set-server=utf8 collation-server=utf8_general_ci skip-name-resolve user=mysql port=3306 basedir=/usr/local/mysql5.7/ datadir=/data/mysql57/data tmpdir=/tmp log-error=/data/mysql57/log/mysqld57.log pid-file=/data/mysql57/mysqld57.pid
Mysql5.7初始化：
#指定了配置文件路径。不指定就会默认/etc/my.cnf，不利于后期的多实例安装
[root@localhost mysql5.7]#/usr/local/mysql5.7/bin/mysqld --defaults-file=/usr/local/mysql5.7/my.cnf --initialize --user=mysql --basedir=/usr/local/mysql5.7/ --datadir=/data/mysql57/data
修改mysql5.7启动脚本：分别修改basedir、datadir、conf的路径
拷贝启动脚本：
[root@localhost mysql5.7]# cp -a ./support-files/mysql.server /etc/init.d/mysql57
启动mysql5.7
[root@localhost mysql5.7]#/etc/init.d/mysql57 start
查看临时密码：
[root@localhost mysql5.7]# cat /data/mysql57/log/mysqld57.log | grep password 2022-09-23T05:25:47.783251Z 1 [Note] A temporary password is generated for root@localhost: nd>phWNwB7YS 2022-09-23T05:35:41.498538Z 0 [Note] Shutting down plugin 'sha256_password' 2022-09-23T05:35:41.498540Z 0 [Note] Shutting down plugin 'mysql_native_password'
重置密码：
[root@localhost mysql5.7]# ./bin/mysql -S /tmp/mysql57.sock -uroot -p '临时密码' Enter password:

三、安装PHP
依赖包安装：
yum -y install gcc gcc-c++ openssl readline-devel openssl-devel curl-devel curl libjpeg-devel libjpeg gd-devel gd libxslt-devel libxslt bzip2-devel bzip2 sqlite-devel autoconf oniguruma-devel
以上依赖包出现无法下载安装情况，请更换使用阿里源---> Centos7更换阿里源
安装libzip
直接使用迅雷下载，参考链接：https://libzip.org/download/libzip-1.3.2.tar.gz
上传服务器，解压编译安装：
[root@localhost src]# tar zxvf libzip-1.3.2.tar.gz [root@localhost src]#cd libzip-1.3.2 [root@localhost src]# ./configure && make && make install [root@localhost libzip-1.3.2]# whereis libzip libzip: /usr/local/lib/libzip.so /usr/local/lib/libzip.la /usr/local/lib/libzip.a [root@localhost libzip-1.3.2]# export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/"
PHP源码包导入服务器，解压进入编译安装
[root@localhost memcached-3.1.5]# cd /usr/local/src/php-7.4.32 [root@localhost php-7.4.32]# ./configure --prefix=/usr/local/php7 \ --with-config-file-path=/etc \ --enable-fpm --disable-debug \ --disable-rpath --enable-shared \ --enable-soap --with-openssl \ --enable-bcmath --with-iconv \ --with-bz2 --enable-calendar \ --with-curl --enable-exif \ --enable-ftp --enable-gd \ --with-jpeg --with-zlib-dir \ --with-freetype --with-gettext \ --enable-mbstring --enable-pdo \ --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd \ --with-readline --enable-shmop --enable-simplexml \ --enable-sockets --with-zip \--enable-mysqlnd-compression-support \ --with-pear --enable-pcntl --enable-posix [root@localhost php-7.4.32]#make && make install #拷贝配置文件 [root@localhost php-7.4.32]# cp -a php.ini-development /usr/local/php7/etc/php.ini #拷贝启动脚本并授权 [root@localhost php-7.4.32]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm [root@localhost php-7.4.32]# chmod +x /etc/init.d/php-fpm #拷贝配置文件 [root@localhost php-7.4.32]# cd /usr/local/php7/etc/ [root@localhost etc]# cp -a php-fpm.conf.default php-fpm.conf [root@localhost etc]# cp -a php-fpm.d/www.conf.default php-fpm.d/ 建立软链接： [root@localhost etc]# ln -s /usr/local/php7/bin/* /usr/local/bin/ [root@localhost etc]# ln -s /usr/local/php7/sbin/* /usr/local/sbin/ [root@localhost etc]# php -v PHP 7.4.32 (cli) (built: Oct 10 2022 04:04:28) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies 启动php-fpm [root@localhost etc]# /etc/init.d/php-fpm start Starting php-fpm done [root@localhost etc]# netstat -pltun | grep 9000 tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 93401/php-fpm: mast tcp 0 0 192.168.140.132:9000 0.0.0.0:* LISTEN 23499/php-fpm: mast [root@localhost etc]# ps aux | grep php root 23499 0.0 0.3 240004 6824 ?

四、PHP+Nginx关联
工作原理：Nginx第一时间接收到用户的请求，只要是php的请求都转发到PHP服务器，交由PHP服务器处理！
Nginx服务器配置
#创建nginx的系统用户
[root@localhost html]# useradd -r -s /sbin/nologin nginx
[root@localhost html]# vim /usr/local/nginx/conf/nginx.conf
location ~ \.php$ {
root /www;#这个是PHP的目录，php的文件要放置该目录下
fastcgi_pass 192.168.140.132:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}运行用户设置为nginx系统用户
PHP服务配置：
创建nginx系统用户 [root@localhost html]# useradd -r -s /sbin/nologin nginx #创建放置php的文件目录，并设置目录所有者为nginx [root@localhost ~]# mkdir /www [root@localhost ~]# chown -R nginx:nginx /www/ #修改配置文件： [root@localhost ~]# vim /usr/local/php7/etc/php-fpm.d/www.conf user = nginx group = nginx #php服务器的地址 listen = 192.168.140.132:9000 #进程的管理方式 dynamic为动态管理 static为静态管理 pm = dynamic #静态方式下开启的php-fpm进程数量，在动态方式下他限定php-fpm的最大进程数（这里要注意pm.max_spare_servers的值只能小于等于pm.max_children） pm.max_children = 120 #动态方式下的起始php-fpm进程数量 pm.start_servers = 20 #动态方式空闲状态下的最小php-fpm进程数量 pm.min_spare_servers = 10 #动态方式空闲状态下的最大php-fpm进程数量 pm.max_spare_servers = 30 #保存之后重新加载配置文件 [root@localhost ~]# /etc/init.d/php-fpm reload Reload service php-fpm done #新建一个测试php文件 [root@localhost ~]# vim /www/test.php <html> <h1>welcome to php !</h1> <?php phpinfo(); ?> </html>
最终结果测试：
五、Mysql+PHP
工作原理：需要查询数据相关的操作，都是由PHP连接数据，执行相对应的mysql语句完成的，所以Mysql需要授权，允许PHP服务器远程连接Mysql！
mysql> create user php@'192.168.140.132' identified by "123456"; Query OK, 0 rows affected (0.00 sec) mysql> grant all on *.* to php@192.168.140.132; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
mysql> select user,host,authentication_string from mysql.user; +---------------+-----------------+-------------------------------------------+ | user | host | authentication_string | +---------------+-----------------+-------------------------------------------+ | root | localhost | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | | mysql.session | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | mysql.sys | localhost | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | php | 192.168.140.132 | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | +---------------+-----------------+-------------------------------------------+ 4 rows in set (0.00 sec)
php测试连接mysql：
测试文件：
[root@localhost www]# cat test.php
<html>
<h1>welcome to php !</h1>
<?php
$con = new mysqli('192.168.140.129','php','123456');
if(!$con)
die("connect error:".mysqli_connect_error());
else
echo "connet mysql server ok!\n";
phpinfo();
?>最终效果：
六、phpMyAdmin安装
phpmyadmin的压缩包包含动、静态资源,也就是说动态资源得放在PHP服务器上，静态资源放在Nginx服务器上！
两种方式实现：
1、一台服务器搭建NFS服务，把网页动、静态资源都放在NFS挂载出去的目录上，这样PHP和Nginx都可以同时读取网页资源的文件！
2、静态资源放在Nginx，动态资源放在PHP上，但是phpmyadmin的动静态资源文件繁杂，不好分辨，为了省事，直接在Nginx和PHP服务器上各拷贝一份phpmyadmin的解压包！
Nginx服务器操作：
上传安装包到Nginx的html目录下并解压
[root@localhost html]# tar zxvf phpmyadmin.tar.gz [root@localhost html]#cd phpmyadmin [root@localhost html]chown -R nginx:nginx /usr/local/nginx/
PHP服务器操作：
[root@localhost ~]# cd /www/ [root@localhost www]# ls phpmyadmin phpmyadmin.tar.gz test.php [root@localhost www]# tar zxvf phpmyadmin.tar.gz [root@localhost www]# cd phpmyadmin [root@localhost libraries]# pwd /www/phpmyadmin/libraries #告诉phpmyadmin的mysql地址是哪一个！ [root@localhost libraries]# vim config.default.php $cfg['Servers'][$i]['host'] = 'Mysql的地址';
最终效果：
PHP拓展：
php添加memcache模块
下载参考链接：
http://pecl.php.net/package/memcache
http://pecl.php.net/package/memcached
phpize是用来拓展php新模块的，通过phpize可以建立php的外挂模块
autoconf是一个用于生成shell脚本的工具，可以自动配置软件源代码以适应多种类似POSIX的系统，为了让你的软件包在所有的不同系统上都可以进行编译。
yum install autoconf
源码包导入系统，解压进入源码编译
