环境： centos7.4

本文介绍快速安装lnmp环境，以及redis，php-redis扩展

1. 安装nginx

yum install nginx
##开启nginx
service nginx start

安装成功后，浏览器访问主机公网IP，或者本机的127.0.0.1。会出现以下界面

2.安装MYSQL

yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

yum install mysql-community-server

//开启mysql
service mysqld start

//查看mysql的root账号的密码
grep 'temporary password' /var/log/mysqld.log

//由于mysql5.7之后开启了密码强度校验，具体参看相关文档
MySQL5.7安装及密码安全策略
//在修改密码之前开发机建议去掉或降低mysql5.7的安全策略 本文采取去掉校验

//如果不需要密码策略，添加my.cnf文件中添加如下配置禁用即可：
validate_password = off
//之后重启mysql服务

//登录mysql
mysql -uroot -p

//修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'password';

//修改root用户可远程登录
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION; 

//刷新
flush privileges;

3.安装php

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

//查看
yum search php71w

//安装php以及扩展
yum install php71w php71w-fpm php71w-cli php71w-common php71w-devel php71w-gd php71w-pdo php71w-mysql php71w-mbstring php71w-bcmath

//开启服务
service php-fpm start

//修改/etc/nginx/nginx.conf  使其支持php 见下
//重启nginx
service nginx restart

//server配置
// 将 /etc/nginx/nginx.conf 的server { 80 端口的内容屏蔽或者修改为其他端口}
// 在/etc/nginx/conf.d/ 里追加test.conf (需要在nginx.conf 里开启 include /etc/nginx/conf.d/*.conf;)
// test.conf 内容为
server {
    listen       80;#端口
    server_name localhost admin.com  www.admin.com; # 域名

    root /data/www/; # 网站根目录
    index index.php index.html index.htm;#默认的index

    # 建议放内网
    # allow 192.168.0.0/24;
    # deny all;

    location / {

if (!-e $request_filename) {
 rewrite ^/(.*)$ /index.php?$1 last;#去除url中的index.php 不需要可以不写

}
    }

    location ~ \.php$ {
        try_files $uri = 404;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

测试文件见最后。测试结果如下：（同时在数据库里安装test库和表a）

为什么不是5.7？？？

结果如下（说明db已经连接上并可以访问）：

4.安装redis

yum install redis
//修改配置 
vi /etc/redis.conf
//daemonize yes 后台运行
//appendonly yes 数据持久化
service redis start

redis的实际操作参考如下：

CentOS7 linux下yum安装redis以及使用

5.安装php-redis扩展

//先装git
yum install git

//git下扩展
cd /usr/local/src
git clone https://github.com/phpredis/phpredis.git

//安装扩展
cd phpredis
phpize

[root@VM_103_117_centos phpredis]# phpize
Configuring for:
PHP Api Version:         20160303
Zend Module Api No:      20160303
Zend Extension Api No:   320160303

// 编译php
执行完上一步，我们就有了 configure 配置文件了，接下来配置
[root@VM_103_117_centos phpredis]#./configure
或者执行(php-config可以用 find / -name php-config来查找位置）
[root@VM_103_117_centos phpredis]#./configure --with-php-config=/usr/bin/php-config

接下来是编译安装
[root@VM_103_117_centos phpredis]#make 
[root@VM_103_117_centos phpredis]# make install
Installing shared extensions: /usr/lib64/php/modules/

//修改php配置
vi /etc/php.ini  
加入下面几行：
[redis]
extension_dir =/usr/lib64/php/modules/
extension = redis.so

redis.so文件的路径可以在make install的时候看到

//重启php
service php-fpm restart

重启之后我们打开info.php,已经可以看到redis的扩展信息了

测试结果：

参考：

CentOS7为php7.2安装php-redis扩展

测试nginx，db和redis的testdb.php文件：

<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "test";
 
// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
} 
 
$sql = "SELECT a,b FROM a";
$result = $conn->query($sql);
 
if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "a: " . $row["a"]. " - b: " . $row["b"]. "<br>";
    }
} else {
    echo "0 结果";
}
$conn->close();

// 测试redis
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set("name", "nango");
echo "redis 测试 <br/>";
echo $redis->get('name');

?>

将其制作开机自启动
centos7 支持 systemctl enable xxx来设置自启动。

[root@iz2zeda8uhrd6yloi1xs0dz ~]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@iz2zeda8uhrd6yloi1xs0dz ~]# systemctl enable mysqld
Created symlink from /etc/systemd/system/multi-user.target.wants/mysqld.service to /usr/lib/systemd/system/mysqld.service.
[root@iz2zeda8uhrd6yloi1xs0dz ~]# systemctl enable php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.
[root@iz2zeda8uhrd6yloi1xs0dz ~]# systemctl enable redis  
Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.

用netstat -ntlp 可以查看哪些端口被占用，即服务启动

[root@iz2zeda8uhrd6yloi1xs0dz ~]# netstat -tlnp
