搭建LNMP架构

安装Nginx

要使用官方Nginx源，无需手动编译避免繁琐操作。

手动配置yum源

[root@nginx~]vim /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

执行yum安装

[root@nginx ~]# yum install nginx -y

启动nginx并加入开机自启

[root@nginx ~]# systemctl start nginx
[root@nginx ~]# systemctl enable nginx

安装php（7.1版）

移除旧版php

[root@nginx ~]# yum remove php-mysql-5.4 php php-fpm php-common -y

配置扩展源

[root@nginx nginx]# yum localinstall -y http://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装php7.1版

[root@nginx ~]# yum -y install php71w php71w-cli php71w-common php71w-devel
php71w-embedded php71w-gd php71w-mcrypt php71w-mbstring php71w-pdo php71w-xml php71w-fpm
php71w-mysqlnd php71w-opcache php71w-pecl-memcached php71w-pecl-redis php71w-pecl-mongodb

统一系统权限，修改php-fpm运行的用户和组身份

[root@web02 ~]# sed -i '/^user/c user = www' /etc/php-fpm.d/www.conf
[root@web02 ~]# sed -i '/^group/c group = www' /etc/php-fpm.d/www.conf

创建用户（www）

useradd www

启动php-fpm管理进程，并加入开机自启

root@nginx ~]# systemctl start php-fpm
[root@nginx ~]# systemctl enable php-fpm

配置Nginx连接php，并进行测试

[root@nginx conf.d]# cat /etc/nginx/conf.d/blog.zhangweibin.conf

server {
         listen 80;
        server_name www.zhangweibin.com;
locationn  / {
         root  /code/test;
         index index.php index.html;
        }
location ~ \.php$ {
        root  /code/test;
        fastcgi_index  index.php;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
        }
}

创建对应站点目录

[root@Nginx conf.d]# mkdir /code/test

[root@Nginx conf.d]# vim /code/test/index.php
####该文件内容为测试php成功连接
 

检查Nginx配置

[root@nginx ~]# nginx -t

重载Nginx

[root@nginx ~]# systemctl reload nginx

hosts解析

10.0.0.60 test.zhangweibin.com

测试

浏览器访问：http：//test.zhangweibin.com

安装Mysql（5.7版）

配置Mysql扩展源

[root@nginx ~]# rpm -ivh http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql57-community-release-el7-10.noarch.rpm

yum安装

[root@nginx ~]# yum install mysql-community-server -y

启动Mysql，并加入开机自启

[root@nginx ~]# systemctl start mysqld
[root@nginx ~]# systemctl enable mysqld

使用Mysq初始密码登录数据库

[root@nginx ~]# mysql -uroot -p$(awk '/temporary password/{print $NF}' /var/log/mysqld.log)

修改数据库密码

修改默认密码规则

数据库默认密码规则必须携带大小写字母、特殊符号，字符长度大于8否则会报错。
mysql> set password for root@localhost = password('123456');
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

因此设定较为简单的密码时需要首先修改set global validate_password_policy和_length参数值
mysql> set global validate_password_policy=0;
Query OK, 0 rows affected (0.00 sec)
mysql> set global validate_password_length=1;
Query OK, 0 rows affected (0.00 sec)

修改密码

mysql> set password for root@localhost = password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)

测试php能否连接Mysql

[root@nginx ~]# vim /code/test/mysqli.php

 // 创建连接
 $conn = mysqli_connect($servername, $username, $password);
> // 检测连接
 if (!$conn) {
     die("Connection failed: " . mysqli_connect_error());
 }
 echo "连接成功";
 ?>

部署workpress

下载workpress数据包

[root@nginx ~]# wget https://cn.wordpress.org/wordpress-4.9.4-zh_CN.tar.gz

解压到站点目录

[root@nginx ~]# tar xf wordpress-4.9.4-zh_CN.tar.gz -C /code/test

修改权限

[root@nginx ~]# chown -R www.www /code/test/

创建workpress数据库

[root@http-server ~]# mysql -uroot -p123456
mysql> create database wordpress;
mysql> exit

浏览器访问域名进行workpress安装部署
