实现LNMP与Redis服务对接

先搭建LNMP

安装Nginx

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
yum -y install pcre-devel zlib-devel gcc gcc-c++ make
useradd -M -s /sbin/nologin nginx
cd /opt
tar zxvf nginx-1.12.0.tar.gz -C /opt/
cd nginx-1.12.0/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module
make && make install
## 
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

vim /lib/systemd/system/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=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service
systemctl start nginx.service
systemctl enable nginx.service

安装PHP

yum -y install gd \
libjpeg libjpeg-devel \
libpng libpng-devel \
freetype freetype-devel \
libxml2 libxml2-devel \
zlib zlib-devel \
curl curl-devel \
openssl openssl-devel

cd /opt
tar jxvf php-7.1.10.tar.bz2
cd 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

make && make install

ln -s /usr/local/php/bin/* /usr/local/bin/
ln -s /usr/local/php/sbin/* /usr/local/sbin/

cp /opt/php-7.1.10/php.ini-development /usr/local/php/lib/php.ini	
vim /usr/local/php/lib/php.ini
--1170行--修改
mysqli.default_socket = /usr/local/mysql/mysql.sock
--939行--取消注释，修改
date.timezone = Asia/Shanghai

cd /usr/local/php/etc/
cp  php-fpm.conf.default php-fpm.conf
vim php-fpm.conf
--17行--去掉";"注释
pid = run/php-fpm.pid

#调整扩展配置文件：
cd /usr/local/php/etc/php-fpm.d/
cp www.conf.default www.conf

5、启动php-fpm
/usr/local/php/sbin/php-fpm -c /usr/local/php/lib/php.ini
netstat -anpt | grep 9000

cd /opt/php-7.1.10/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/php-fpm.service
systemctl restart php-fpm.service

配置Nginx支持PHP解析

6、配置 Nginx 支持 PHP 解析
vim /usr/local/nginx/conf/nginx.conf
--65行--取消注释，修改
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;	#将 /scripts 修改为nginx的工作目录
	include        fastcgi_params;
}

systemctl restart nginx.service

安装Redis服务，搭建redis扩展

安装Redis扩展

tar zxvf redis-4.0.2.tgz 
cd /opt/redis-4.0.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --enable-redis
make && make install


4、修改 php 配置文件
vim /usr/local/php/lib/php.ini
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/"	#736行，指定redis模块目录
extension = "redis.so"		#738行，修改参数项名称为extension，指定redis模块名称


systemctl restart php-fpm.service
php -m | grep redis

测试连接性

5、测试连接
cd /usr/local/nginx/html/
vim set.php
<?php
$redis = new redis();
$redis->connect('127.0.0.1', 6379);
$redis->set('test',"1111111111");
echo $redis->get('test');
?>

curl http://127.0.0.1/set.php

vim get.php
<?php
$redis = new redis();
$redis->connect('127.0.0.1', 6379);
$result = $redis->get('test');
var_dump($result);
?>

curl http://127.0.0.1/get.php
//结果：string(10) "1111111111"
