02-location ginx+php

一、location

# 作用: 控制用户请求 uri 的具体路径

# 用法: location [ = | ~ | ~* | ^~ ] uri { ... }

"""多个location时会用上, 但多个location会出现优先级的问题."""

1、Location优先级

#    匹配符         匹配规则                          优先级
#    =                精确匹配                          1 
#    ^~               以某个字符串开头                   2
#    ~                区分大小写的正则匹配                3
#    ~*               不区分大小写的正则匹配              4
#    /                通用匹配，任何请求都会匹配到         5

http://location.kkkedu.com/index.html            location /
http://location.kkkedu.com/documents/1.html        location /documents/
http://location.kkkedu.com/images/1.gif            location ^~ /images/
http://location.kkkedu.com/documents/1.jpg        location ~* .(gif|jpg|jpeg)

2、Location具体使用

server {
    listen 80;
    server_name location2.oldxu.com;

    # 通用匹配，任何请求都会匹配到
    location / {
        root html;
        index index.html;
    }

    # 精准匹配,必须请求的uri是/nginx_status
    location = /nginx_status {
        stub_status;
    }

    # 严格区分大小写，匹配以.php结尾的都走这个location    
    location ~ .php$ {
        default_type text/html;
        return 200 'php访问成功';
    }

    # 严格区分大小写，匹配以.jsp结尾的都走这个location 
    location ~ .jsp$ {
        default_type text/html;
        return 200 'jsp访问成功';
    }

    # 不区分大小写匹配，只要用户访问.jpg,gif,png,js,css 都走这条location
    location ~* .(jpg|gif|png|js|css)$ {
        return 403;
    }

    # 不区分大小写匹配
    location ~* .(sql|bak|tgz|tar.gz|.git)$ {
        deny all;
    }
}

二、Nginx+php

　　--> wordpress

LNMP架构

        L = Linux
        N = Nginx
        M ~= MySQL | Mariadb
        p ~= PHP   | Python

1、LNMP架构安装

php：

[root@kkk-kkk ~]# rpm -e $(rpm -qa |grep php)   #卸载php5版本
[root@kkk-kkk ~]# wget http://cdn.xuliangwei.com/php.zip
[root@kkk-kkk ~]# unzip php.zip 
[root@kkk-kkk ~]# yum localinstall php/*.rpm -y

修改进程运行的身份

[root@kkk-kkk ~]# sed -i 's#user = apache#user = nginx#g' /etc/php-fpm.d/www.conf 
[root@kkk-kkk ~]# sed -i 's#group = apache#group = nginx#g' /etc/php-fpm.d/www.conf 

启动php-fpm

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

nginx+php检查

[root@kkk-kkk ~]# cat /etc/nginx/conf.d/php.kkkedu.com.conf
server {
    listen 80;
    server_name php.kkkedu.com;
    root /code;

    location / {
        index index.php;
    }

    location ~ .php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

[root@kkk-kkk ~]# cat /code/index.php 
        <?php
            phpinfo();
        ?>

安装mariadb

[root@kkk-kkk ~]# yum install mariadb mariadb-server -y
[root@kkk-kkk ~]# systemctl enable mariadb
[root@kkk-kkk ~]# systemctl start mariadb
[root@kkk-kkk ~]# mysqladmin password 'Oldxu.com123'
[root@kkk-kkk ~]# mysql -uroot -pOldxu.com123
MariaDB [(none)]> 
MariaDB [(none)]> create database wordpress charset utf8;

测试php+MariaDB是否成功

[root@kkk-kkk ~]# cat /code/mysql.php 
   <?php
    $servername = "localhost";
    $username = "root";
    $password = "Oldxu.com123";

    // 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";
    ?>

[root@kkk-kkk ~]# php /code/mysql.php 
        php连接MySQL数据库成功

2、部署Wordpress

第一步: 下载代码,存储至指定位置,变更权限

[root@kkk-kkk ~]# cd /code/
[root@kkk-kkk code]# wget https://cn.wordpress.org/latest-zh_CN.tar.gz
[root@kkk-kkk code]# tar xf latest-zh_CN.tar.gz 
[root@kkk-kkk code]# chown -R nginx.nginx wordpress/

第二步: 编写Nginx配置文件

[root@kkk-kkk code]# cat /etc/nginx/conf.d/blog.kkkedu.com.conf 
server {
    listen 80;
    server_name blog.kkkedu.com;
    root /code/wordpress;

    location / {
        index index.php;
    }

    location ~ .php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

[root@kkk-kkk code]# nginx -t
[root@kkk-kkk code]# systemctl reload nginx

第三步: 配置域名解析.访问浏览器.安装该产品

3、安装EduSoho

mkdir /code

cd /code
rz #上传文件
tar xf edusoho-8.2.17.tar.gz

#注意：我们的进程能够以什么方式去访问一个文件或目录，取决于进程所运行的用户身份对该文件有什么权限

修改权限

chown -R nginx.nginx edusoho

增加EduSoho nginx配置

vi /etc/nginx/conf.d/edusoho.kkkedu.conf
server {
    listen 80;
    server_name edu.kkkedu.com;
    root /code/edusoho/web;
    client_max_body_size 1024m;        #允许上传视频大小限制
    client_body_buffer_size 100m;    #缓冲区大小(太小会提示a client request body is buffered to a temporary)

    location / {
        index app.php;
        try_files $uri @rewriteapp;
    }

    location @rewriteapp {
        rewrite ^(.*)$ /app.php/$1 last;
    }

    location ~ ^/udisk {
        internal;
        root /code/edusoho/app/data/;
    }

    location ~ ^/(app|app_dev).php(/|$) {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_split_path_info ^(.+.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param  HTTPS              off;
        fastcgi_param HTTP_X-Sendfile-Type X-Accel-Redirect;
        fastcgi_param HTTP_X-Accel-Mapping /udisk=/code/edusoho/app/data/udisk;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 8 128k;
    }

    location ~* .(jpg|jpeg|gif|png|ico|swf)$ {
        expires 3y;
        access_log off;
        gzip off;
    }

    location ~* .(css|js)$ {
        access_log off;
        expires 3y;
    }

    location ~ ^/files/.*.(php|php5)$ {
        deny all;
    }

    location ~ .php$ {
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_split_path_info ^(.+.php)(/.*)$;
        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param  HTTPS              off;
        include        fastcgi_params;
    }
}

重启nginx服务

nginx -t
systemctl restart nginx

修改php.ini 配置文件,调整解析器支持的最大上传限制

vim /etc/php.ini
upload_max_filesize = 1024M
post_max_size = 1024M

systemctl restart php-fpm
