揭示板这个套图网站我一直很喜欢，不过一直被墙，域名也一直再换。

虽然订阅了它的域名发布页:http://www.anonymous-fan.com

不过还是觉得麻烦。

特别是手机浏览器(移动4G网络)打开网页看不到图片,也很烦。

所以最近就觉得用DO闲置的VPS搞个代理。主意不错！！！

经过一番研究，主要需要代理三个方面。

我挑选了 地址二：http://www.1press.info 这个域名。

1.网站首页
nginx 配置如下：

    location / {
        proxy_set_header Host 'www.1press.info';
        proxy_set_header Referer 'www.1press.info';
        proxy_pass http://www.1press.info;
        sub_filter 'www.1press.info' 'dsb.caonima.pw:81';
        sub_filter '27.255.79.40' 'dsb.caonima.pw:81/img1';
        sub_filter '174.139.202.79' 'dsb.caonima.pw:81/img2';
        sub_filter_once off;
    }

2.套图CDN
nginx 配置如下：

    location ~/img2(.*)$ {
        proxy_pass_request_headers on;
        proxy_pass_request_body off;
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host 'www.1press.info';
        proxy_set_header Referer 'www.1press.info';
        proxy_pass   http://174.139.202.79$1;
    }

3.其他图片资源
nginx 配置如下：

    location ~/img1(.*)$ {
        proxy_pass_request_headers on;
        proxy_pass_request_body off;
        proxy_set_header X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host 'www.1press.info';
        proxy_set_header Referer 'www.1press.info';
        proxy_pass   http://27.255.79.40$1;
    }

保存配置，刷新nginx 配置。

访问 http://dsb.caonima.pw:81,一切OK。美滋滋~

今天吃完饭回来就在想上午的那个方案虽然可行，但是有个弊端。

就是每上一个新版本，除了上传新版本文件夹之外 还得编辑下 nginx vhost 配置，新增一个虚拟主机。

说麻烦虽然不麻烦 不过也挺烦人的。没有做到自适应，需要人工干预。

所以又折腾了一下。

配置如下：

server {
    listen       80;
    server_name  haha.17ping.cn;
    root         /data/www/sdkHoster;

    location / {
        index    index.php index.htm index.html;
        autoindex on;
    }

    location ~ /([\w\d_]+)/([\w/]*)$ {
        index    index.php index.htm index.html;
        try_files $uri $uri/ /$1/public/index.php?$query_string;
        #return 500 $1;
    }

#    location /sdk1_0 {
#       root    /data/www/sdkHoster;
#       index   index.php index.htm index.html;
#       try_files $uri $uri/ /sdk1_0/public/index.php?$query_string;
#    }

#    location /sdk1_1 {
#       root    /data/www/sdkHoster;
#       index   index.php index.htm index.html;
#       try_files $uri $uri/ /sdk1_1/public/index.php?$query_string;
#    }

    location ~ \.php$ {
        set $newurl $request_uri;
        if ($newurl ~ ^/sdk([\d_]+)(.*)$) {
                set $newurl $2;
        }
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        #fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
        include        fastcgi_params;
        fastcgi_param REQUEST_URI $newurl;
    }

    location ~ \.(css|js|swf|php|htm|html)$ {
        add_header Cache-Control no-store;
    }

    location ~ /\.ht {
        deny  all;
    }
}

保存，重载配置。

手动复制了一份 sdk1_2 目录，重命名为sdk1_2.
访问 http://haha.17ping.cn/sdk1_2/ 成功，美滋滋。

最近公司在搞lumen 框架，需要用到一个场景。

就是
XXX.com/apiv1/controller/action
XXX.com/apiv2/controller/action
XXX.com/apiv3/controller/action
以此类推

由于lumen 比较坑，必须用项目下的public 为 server_root.

本来我们有一个很懒的解决方案就是用无限的子域名堆出无限个的virtualhost.
apiv1.XXX.com/controller/action
apiv2.XXX.com/controller/action
apiv3.XXX.com/controller/action

不过后来想到域名生效、域名子域名数量限制等问题，就放弃了。

老老实实搞nginx 配置。

经过半天的折腾，完美解决。
nginx 配置如下：

server {
    listen       80;
    server_name  haha.17ping.cn;
    root         /data/www/sdkHoster;

    location / {
        index    index.php index.htm index.html;
        autoindex on;
    }

    location /sdk1 {
        root    /data/www/sdkHoster;
        index   index.php index.htm index.html;
        try_files $uri $uri/ /sdk1/public/index.php?$query_string;
    }

    location /sdk2 {
        root    /data/www/sdkHoster;
        index   index.php index.htm index.html;
        try_files $uri $uri/ /sdk2/public/index.php?$query_string;
    }

    location ~ \.php$ {
        set $newurl $request_uri;
        if ($newurl ~ ^/sdk(\d+)(.*)$) {
                set $newurl $2;
        }
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        #fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
        include        fastcgi_params;
        fastcgi_param REQUEST_URI $newurl;
    }

    location ~ \.(css|js|swf|php|htm|html)$ {
        add_header Cache-Control no-store;
    }

    location ~ /\.ht {
        deny  all;
    }
}

效果如下：

root@iZuf6c8x9fhxje4raqhanuZ:/data/www/sdkHoster# curl -X POST http://haha.17ping.cn/sdk1/account/index
{"code":0,"message":"OK","data":{"msg":"\u5982\u9047\u8d26\u53f7\u95ee\u9898\u8bf7\u8054\u7cfbQQ:115693753"}}

root@iZuf6c8x9fhxje4raqhanuZ:/data/www/sdkHoster# curl -X POST http://haha.17ping.cn/sdk2/account/index
{"code":0,"message":"OK","data":{"msg":"\u5982\u9047\u8d26\u53f7\u95ee\u9898\u8bf7\u8054\u7cfbQQ:115693753"}}
root@iZuf6c8x9fhxje4raqhanuZ:/data/www/sdkHoster#

不过这个配置有个缺点，就是如果url后面不跟任何东西的话，比如(http://haha.17ping.cn/sdk2) 就会找不到index.php.
一般这种页面 lumen 是用来打印版本信息的。

如果有人觉得强迫症不爽的话，直接从public 下面复制一个 index.php 到 上一级目录，然后修改14行的

$app = require __DIR__.'/../bootstrap/app.php';
改成
$app = require __DIR__.'/./bootstrap/app.php';

把导入的相对路径调成平级就行了。效果如下：

root@iZuf6c8x9fhxje4raqhanuZ:/data/www/sdkHoster# curl -X GET http://haha.17ping.cn/sdk1/
Lumen (5.5.2) (Laravel Components 5.5.*)
root@iZuf6c8x9fhxje4raqhanuZ:/data/www/sdkHoster# curl -X GET http://haha.17ping.cn/sdk2/
Lumen (5.5.2) (Laravel Components 5.5.*)
root@iZuf6c8x9fhxje4raqhanuZ:/data/www/sdkHoster#

最近接到邮件，说自己SSL证书将于10日内过期，于是赶紧续期。renew.

使用 letsencrypt 官方推荐的客户端 Certbot 完成操作。

下载该工具，根据各自的系统和包管理器，下载安装。

由于我的系统比较老，所以下载了 binary 文件。

wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto

给了执行权限，继续操作。

搞定！！！！

最近跟风SSL，便搞了一个SSL证书到自己的网站。

到 https://startssl.com/Certificates 注册会员，验证邮箱和域名。

然后申请 Class 1 (Not Validated) 的 DV SSL Certificate for Free User (Not Validated)，这是给初级别用户的证书，因为不用验证身份证，拍照啥的。

1.Please enter the full hostname for SSL certificate (e.g: mail.domain.com):

输入自己的域名，可以是好几个子域名，换行隔开。

2.Please submit your Certificate Signing Request (CSR):

选择第一个 Generated by Myself。

在shell 执行 “openssl req -newkey rsa:2048 -keyout xxx.key -out xxx.csr ”，需要安装openssl 套件。

cat xxx.csr

把内容贴入下方的文本域，点击提交。

如下：

[root@xzx ssl]# openssl req -newkey rsa:2048 -keyout blog.key -out blog.csr
Generating a 2048 bit RSA private key
