一、nginx状态模块及权限控制补充

1.2 nginx状态模块

通过监控软件查看nginx的状态

[root@web01 ~]# curl status.oldboy.com
Active connections: 1 
server accepts handled requests
 23 23 23 
Reading: 0 Writing: 1 Waiting: 0 

\\------------------分别代表的含义-----------------------------------
Active connections: 1     当前的连接数量(已经建立的连接)

server accepts             服务器接收到的请求数量
server handled             服务器处理的请求数量
server requests            用户一共向服务器发出多少请求 

Reading: 0                 当前nginx正在读取的用户请求头的数量 
Writing: 1                 当前nginx正在响应用户请求的数量
Waiting: 0                 当前等待被nginx处理的请求数量 

1.2 权限控制

实例1.2.1 基于用户登录配置(简单验证)
1>在status.conf 中配置配置用户及密码

[root@web01 /etc/nginx/conf.d]# cat status.conf 
server{ 
    listen   80; 
    server_name   status.oldboy.com;
    stub_status  on;
    access_log  off;
    auth_basic "Auth access Blog Input your Passwd!";   \\指定用户密码提示
    auth_basic_user_file /etc/nginx/htpasswd;     \\指定用户密码文件

}

2>添加密码文件

[root@web01 /etc/nginx/conf.d]# htpasswd -bc /etc/nginx/htpasswd  oldboy   oldboy
Adding password for user oldboy

3>设置密码文件的权限为600,所有者及属组为nginx

\\修改密码文件的权限为600
[root@web01 /etc/nginx/conf.d]# chmod 600 /etc/nginx/htpasswd

\\修改密码文件的所有者及所有属组为nginx
[root@web01 /etc/nginx/conf.d]# chown nginx.nginx /etc/nginx/htpasswd

4>nginx检查语法

[root@web01 /etc/nginx/conf.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

5>启动nginx服务

[root@web01 /etc/nginx/conf.d]# systemctl reload nginx

6>浏览器输入域名检查,如图:

1.3 #取出本地的状态码

[root@web01 /etc/nginx/conf.d]# curl  10.0.0.7
HTTP/1.1 200 OK
Server: nginx/1.16.0
Date: Thu, 06 Jun 2019 01:58:40 GMT
Content-Type: text/html
Content-Length: 15
Last-Modified: Wed, 05 Jun 2019 09:52:47 GMT
Connection: keep-alive
ETag: "5cf790ef-f"
Accept-Ranges: bytes

[root@web01 ~]# curl 10.0.0.7|awk 'NR==1{print $2}'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100    16  100    16    0     0  22471      0 --:--:-- --:--:-- --:--:-- 16000

[root@web01 ~]# curl -sI 10.0.0.7|awk 'NR==1{print $2}'
200

curl 常见的参数:
  -s:不显示网页的内容
  -w:什么输出完成后
  -o:把网站页面的内容写入到哪里或黑洞`

二、 nginx的location规则

2.1 location的作用

根据用户请求的URL来执行不同的应用,即URI的内容。

2.2 location语法

location[=|~|~*|^~]url{
           ……
        }

2.3 location语法说明

| location | [=||*|^~] | url | {……} |
| --- | --- | --- | --- |
| 指令 | 匹配标识 | 匹配的网站网址 | 匹配URL后要执行的配置段 |

2.4 匹配标识分别代表的含义

匹配标识 含义
= 精确
~ 区分大小写的正则匹配
~* 不区分大小写的正则匹配
^~ 不做正则表达式的检查

2.5 location的优先级

注:验证这个之前将 /etc/nginx/conf.d目录下的conf文件只保留01-www.conf,其他全部压缩了,不然会影响后面的验证

[root@web01 /etc/nginx/conf.d]# cat 01-www.conf
server {
    listen       80;
    server_name  www.oldboy.com;
    root   html/www;
    location / {
       return 200  "location / \n";
    }
    location = / {
        return 200 "location = \n";
    }
    location /documents/ {
        return 200 "location /documents/ \n";
    }
    location ^~ /images/ {
        return 200 "location ^~ /images/ \n";
    }
    location ~* \.(gif|jpg|jpeg)$ {
        return 200 "location ~* \.(gif|jpg|jpeg) \n";
    }
    access_log off;
}

以上是01-www.conf配置文件中的内容,然后进行以下测试

[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7
location = 

[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/
location = 

[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/oldboy.html
location / 

[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/documents/alex.txt
location /documents/ 

[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/lidao/documents/alex.txt
location / 

[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/oldboy.jpg
location ~* \.(gif|jpg|jpeg) 

#验证/documents与~* 的优先级
[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/documents/oldboy.jpg
location ~* \.(gif|jpg|jpeg) 

#验证 ~* 与 ^~ 优先级
[root@web01 /etc/nginx/conf.d]# curl 10.0.0.7/images/oldboy.jpg
location ^~ /images/ 

image

2.6 location规则应用:

1>限制敏感目录

location /admin{
    deny all;
}

2>区分不同的文件类型

location ~* \.(gif|jpg|jpeg)$ {
    在用户浏览器缓存10年
}

三、LNMP搭建博客网站

3.1 搭建网站必备环境

PHP网站用LNMP/LEMP
Java网站用LNMT
静态/动态

LNMP分别是L=Linux、N=Nginx、M=MySQL、P=PHP
LNMT分别是L=Linux、N=Nginx、M=MySQL、T=Tomcat

3.2 LNMP架构环境部署

image

3.2.1配置nginx的yum源

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

3.2.2安装nginx

yum install -y nginx

3.2.3 启动nginx,并加入开机自启动

启动服务:systemctl start nginx
设置开机自启:systemctl enable nginx

3.2.4 使用第三方扩展源安装php7.1

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

由于网络的原因,也可以将这两个包先下载到本地,在导入到系虚拟机中安装

rpm -ivh epel-release-latest-7.noarch.rpm
rpm -ivh webtatic-release.rpm

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

修改nginx配置(只保留/etc/nginx/conf.d/02-blog.conf,其他都用gzip压缩了)※※

[root@web01 /etc/nginx/conf.d]# vim 02-blog.conf 
server   {
    listen       80;
    server_name  blog.oldboy.com;
    access_log  /var/log/nginx/access_blog.log  main;
    root   /usr/share/nginx/html/blog;
    location / {
    index  index.php index.html index.htm;
    }
   location ~* \.(php|php5)$ {
       fastcgi_pass   127.0.0.1:9000;
       fastcgi_index  index.php;
       fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
       include        fastcgi_params;
  }
}

\\----------------上面的含义----------------------------
fastcgi_pass      \\把动态请求交给php-fpm
fastcgi_index    \\默认访问的首页文件
fastcgi_param     \\设置nginx把请求转发给php的时候的参数
$document_root    \\网站的站点目录
$fastcgi_script_name    \\请求URI

image

3.2.5 安装mariadb数据库(MySQL)

yum install -y mariadb-server

3.2.6 启动mariadb数据库,并设置开机自启

启动服务:systemctl start mariadb.service
设置开机自启:systemctl enable mariadb.service

3.2.7 检查MySQL端口

[root@web01 /etc/nginx/conf.d]#  ss -lntup |grep mysql
tcp    LISTEN     0      50        *:3306                  *:*                   users:(("mysqld",pid=74317,fd=13))
[root@web01 /etc/nginx/conf.d]# 

3.3 MySQL数据库的基础操作

3.3.1 进入数据库

1>MySQL命令(mysql客户端)
2>进入本地指定数据库:mysql -u wordpress -p123456或mysql -uwordpress -p回车输入密码
3>远程进入指定数据库:mysql -uwordpress -p123456 -h 172.16.1.7

3.3.2 查看操作
1>查看系统中所有数据库

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.00 sec)

MariaDB [(none)]> 

2>查看系统中所有的用户(显示指定某些表字段)

MariaDB [(none)]> select user,host from mysql.user;
+------+-----------+
| user | host      |
+------+-----------+
| root | 127.0.0.1 |
| root | ::1       |
|      | localhost |
| root | localhost |
|      | web01     |
| root | web01     |
+------+-----------+
6 rows in set (0.00 sec)

3>查询横向显示所有表字段

select * from mysql.user

4>查询纵向显示所有表字段

select * from mysql.user\G

5>显示当前所用的用户

select user();

6>使用数据库(进入指定数据库)

use mysql;

7>显示当前使用的数据库

select database();

8>只显示1条数据

MariaDB [(none)]> select * from mysql.user limit 1 ;
MariaDB [(none)]> select * from mysql.user limit 1 \G

3.3.3 创建操作
1>创建数据库

MariaDB [(none)]> create database wordpress;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
| wordpress          |
+--------------------+
5 rows in set (0.00 sec)

2>创建用户

MariaDB [(none)]> grant all      on wordpress.*       to 'wordpress'@'172.16.1.%'  identified by '123456';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> grant all      on wordpress.*       to 'wordpress'@'localhost'  identified by '123456';
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> 

3.3.4删除操作

1>删除数据库

drop database wordprssd(数据库名);

2>删除用户

drop user 'oldboy'@'localhost'
生效用户:flush privileges(删除用户的时候使用)

3.3.5更新权限信息:修改用户信息之后需要跟新权限信息

3.3.6备份操作

1>导出所有的数据库

mysqldump -uroot -p -all-database >/root/all.sql
mysqldump -uroot -p -A >/root/all.sql

3.3.7恢复数据库

mysql -uroot -p </root/all.sql

3.3.8打包压缩导出的数据库

tar、zip与unzip、gzip与gzip -d

注:退出用Ctrl+d,不要使用Ctrl+c

3.4 配置PHP

由于nginx运行起来是nginx用户,且为了和PHP很好的沟通,估让PHP运行起来也应该是nginx用户,所以要进行以下修改

[root@web01 ~]# egrep  -n '^user|^group' /etc/php-fpm.d/www.conf 
8:user = nginx
10:group = nginx

启动服务

systemctl restart php-fpm.service 

检查端口

[root@web01 ~]# ss -lntup|grep 9000
tcp    LISTEN     0      128    127.0.0.1:9000                  *:*                   users:(("php-fpm",pid=15344,fd=9),("php-fpm",pid=15343,fd=9),("php-fpm",pid=15342,fd=9),("php-fpm",pid=15341,fd=9),("php-fpm",pid=15340,fd=9),("php-fpm",pid=15339,fd=7))

检查进程

[root@web01 ~]# ps -ef |grep php 
root     15339     1  0 12:42 ?        00:00:00 php-fpm: master process (/etc/php-fpm.conf)
nginx    15340 15339  0 12:42 ?        00:00:00 php-fpm: pool www
nginx    15341 15339  0 12:42 ?        00:00:00 php-fpm: pool www
nginx    15342 15339  0 12:42 ?        00:00:00 php-fpm: pool www
nginx    15343 15339  0 12:42 ?        00:00:00 php-fpm: pool www
nginx    15344 15339  0 12:42 ?        00:00:00 php-fpm: pool www
root     15348  3551  0 12:43 pts/0    00:00:00 grep --color=auto php

3.5 检查与测试

3.5.1 检查nginx与php之间连接是否OK

[root@web01 /usr/share/nginx/html/blog]# cat info.php 
<?php
phpinfo();
?>

image

3.5.2 检查php与MySQL连接是否OK

[root@web01 /usr/share/nginx/html/blog]# cat mysqli.php 
<?php
$servername = "localhost";
$username = "wordpress";
$password = "123456";

// 创建连接
$conn = mysqli_connect($servername, $username, $password);

// 检测连接
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "php连接MySQL数据库成功";
?>

image

3.6 搭建wordpress博客(代码上线)

官网:https://cn.wordpress.org/

1>下载wordpress博客的源码,上传到虚拟机中,并解压之后将wordpress的所有内容移动到blog目录下
mv wordpress/* /usr/share/nginx/html/blog/

[root@web01 ~]# ll /usr/share/nginx/html/blog

[root@web01 ~]# mv wordpress /usr/share/nginx/html/blog/

修改blog站点目录的所有者及属组为nginx

[root@web01 /usr/share/nginx/html/blog]# chown -R nginx.nginx wordpress/
[root@web01 /usr/share/nginx/html/blog]# ls -ld wordpress/
drwxr-xr-x 5 nginx nginx 4096 May 22 02:24 wordpress/
[root@web01 /usr/share/nginx/html/blog]# 

2>在浏览器输入http://10.0.0.7
