CentOS7 部署LNMP+Redis环境

在主机192.168.4.57部署LNMP 环境
配置PHP支持redis
编写网站脚本，把数据存储到redis服务器192.168.4.50

一：在主机192.168.4.57部署LNMP 环境

1）安装源码nginx软件及php-fpm

[root@lnmp~] # yum -y install gcc pcre-devel zlib-devel  //安装依赖
[root@lnmp~] # tar -zxvf nginx-1.12.2.tar.gz  //解压
[root@lnmp~] # cd nginx-1.12.2  //进源码目录
[root@lnmp~] # ./configure  //配置
[root@lnmp~] # make &&  make install   //编译安装

[root@lnmp~] # ls /usr/local  //查看安装目录
bin  etc  games  include  lib  lib64  libexec  nginx  sbin  share  src
[root@lnmp~] #ls /usr/local/nginx  //查看目录列表
conf  html  logs  sbin

[root@lnmp~] #yum -y install php-fpm  //安装php-fpm

2）修改配置nginx.conf

[root@lnmp~] # vim   +65  /usr/local/nginx/conf/nginx.conf
      location ~ \.php$ {
              root           html;
              fastcgi_pass   127.0.0.1:9000;
              fastcgi_index  index.php;
              include        fastcgi.conf;
       }
[root@lnmp~] #  /usr/local/nginx/sbin/nginx  -t     //测试修改
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

3）启动php-fpm服务和启动nginx服务

[root@lnmp~] #  systemctl  start php-fpm  //启动服务
[root@lnmp~] #  netstat  -utnlp  | grep  :9000  //查看端口

[root@lnmp~] # /usr/local/nginx/sbin/nginx
[root@lnmp~] # netstat  -utnlp  | grep  :80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      23505/nginx: master

4）测试配置

[root@lnmp~] # vim  /usr/local/nginx/html/test.php  //编写php文件
<?php
        echo  "hello world!!!";
?>

[root@lnmp~] # curl  http://localhost/test.php     //访问nginx服务

二：配置PHP支持redis

1）安装php扩展

[root@lnmp~] # yum -y  install php php-devel automake autoconf //安装依赖
[root@lnmp~] # tar -zxf php-redis-2.2.4.tar.gz //安装扩展包
[root@lnmp~] # cd phpredis-2.2.4/
[root@lnmp~] # phpize            //生成配置文件php-config及 configure命令
Configuring for:
PHP Api Version:         20100412
Zend Module Api No:      20100525
Zend Extension Api No:   220100525

[root@lnmp~] # ./configure  --with-php-config=/usr/bin/php-config //配置
[root@lnmp~] # make //编译
[root@lnmp~] # make install //安装

2）修改php.ini文件

[root@lnmp~] #vim /etc/php.ini
728 extension_dir = "/usr/lib64/php/modules/"  //模块文件目录
730 extension = "redis.so"  //模块文件名

[root@lnmp~] # systemctl  restart php-fpm //重启php-fpm服务
[root@lnmp~] # php -m | grep  -i redis     //查看已加载的模块
redis

三：redis服务器配置

对Redis服务器192.168.4.50做如下配置： 端口号 6350 连接密码 123456
1）修改配置文件

[root@redis utils]# /etc/init.d/redis_6379 stop

[root@redis utils]# vim /etc/redis/6379.conf
...
bind  192.168.4.50                //设置服务使用的ip
port 6350                            //更改端口号
requirepass 123456                //设置密码

2）修改启动脚本

[root@redis ~]# vim  +43  /etc/init.d/redis_6379
$CLIEXEC -h 192.168.4.50 -p 6350 -a 123456  shutdown

3）启动服务

 [root@redis ~]# /etc/init.d/redis_6379  start
Starting Redis server...
 [root@redis ~]# 
 [root@redis ~]# netstat -utnlp  | grep redis-server
 tcp        0      0 192.168.4.50:6350       0.0.0.0:*               LISTEN      11523/redis-server  

4）测试配置，访问服务存取数据

[root@redis ~]# redis-cli -h 192.168.4.50 -p 6350 -a 123456 //访问服务
192.168.4.50:6350> ping
PONG
192.168.4.50:6350> keys *
(empty list or set)
192.168.4.50:6350> 
192.168.4.50:6350> set x 99
OK
192.168.4.50:6350>
192.168.4.50:6350> exit

四：测试配置：编写网站脚本，把数据存储到redis服务器192.168.4.50

1）查看192.168.4.50主机的redis服务是否运行

[root@redis~] # netstat -utnlp  | grep redis-server
tcp        0      0 192.168.4.50:6350       0.0.0.0:*               LISTEN      11523/redis-server  

[root@redis~] # redis-cli -h 192.168.4.50 -p 6350 -a 123456 //访问服务
192.168.4.50:6350> ping
PONG
192.168.4.50:6350> exit 

2）编写网站脚本

[root@lnmp~] # vim  /usr/local/nginx/html/linkredis.php
<?php
$redis = new redis();
$redis->connect("192.168.4.50","6350");
$redis->auth("123456");
$redis->set("linux","redhat");
echo $redis->get("linux");
?>

3）访问网站脚本

[root@lnmp~] #curl  http://localhost/linkredis.php      //访问nginx服务
   redhat   

4）在192.168.4.50 服务器，查看数据

[root@redis~] # redis-cli -h 192.168.4.50 -p 6350 -a 123456 //连接redis服务
192.168.4.50:6350> keys *   //查看变量
1) "linux"
192.168.4.50:6350> 
192.168.4.50:6350> get linux //获取值
"redhat"
192.168.4.50:6350>
