4.1 问题
具体要求如下：
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
4.2 步骤
实现此案例需要按照如下步骤进行。
步骤一：在主机192.168.4.57部署LNMP 环境
1）安装源码nginx软件及php-fpm
]#yum -y install gcc pcre-devel zlib-devel //安装依赖
]#tar -zxvf nginx-1.12.2.tar.gz //解压
]#cd nginx-1.12.2 //进源码目录
]#./configure //配置
……

[root@localhost nginx-1.12.2]# ls /usr/local //查看安装目录

[root@localhost nginx-1.12.2]#
[root@localhost nginx-1.12.2]# ls /usr/local/nginx //查看目录列表
conf html logs sbin
[root@localhost nginx-1.12.2]#
]#yum -y install php-fpm //安装php-fpm
……
……
已安装:
php-fpm.x86_64 0:5.4.16-45.el7
作为依赖被安装:
libzip.x86_64 0:0.10.1-8.el7 php-common.x86_64 0:5.4.16-45.el7
完毕！
2）修改配置nginx.conf
] # 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;
}
:wq
]# /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）启动服务
启动php-fpm服务
]# systemctl start php-fpm //启动服务
]# netstat -utnlp | grep :9000 //查看端口
启动nginx服务
]# /usr/local/nginx/sbin/nginx
]# 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
]# vim /usr/local/nginx/html/test.php //编写php文件
<?php
echo "hello world!!!";
?>
:wq
]# curl http://localhost/test.php //访问nginx服务
hello world!!!
步骤二：配置PHP支持redis
1）安装php扩展
[root@host71 ~]# rpm -q php php-devel
未安装软件包 php
未安装软件包 php-devel
[root@host71 ~]#
[root@host71 ~]# rpm -q automake autoconf
未安装软件包 automack
未安装软件包 autoconf
[root@host71 ~]#
[root@host71 ~]# yum -y install php php-devel automake autoconf //安装依赖
]# tar -zxf php-redis-2.2.4.tar.gz //安装扩展包
]# cd phpredis-2.2.4/
]# 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
]# ./configure --with-php-config=/usr/bin/php-config //配置
]# make //编译
]# make install //安装
2）修改php.ini文件
]#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
:wq
]# systemctl restart php-fpm //重启php-fpm服务
]# php -m | grep -i redis //查看已加载的模块
redis
步骤三：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@host50 ~]# netstat -utnlp | grep redis-server
tcp 0 0 192.168.4.50:6350 0.0.0.0:* LISTEN 11523/redis-server
[root@host50 ~]#
[root@host50 ~]# 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
]# 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");
?>
:wq
3）访问网站脚本
]#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@host50 ~]# 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>
