# 前言

\n

科学上网的方法有多种,有很多第三方提供的免费方案,这些方案优缺点暂时不予讨论。实际工作生活中还是会有需要自己搭建的情况,这次介绍的是使用 squid+stunnel 方案进行搭建。

\n

# 准备

\n

一台可以访问外网的服务器,如香港的云主机并安装 Ubuntu 系统。

\n
# squid 部分
\n\n
apt-get install -y squid
\n
\n

生成用户文件

\n
\n
apt-get install apache2-utils
htpasswd -c /etc/squid/squid_user.txt 用户名
\n

修改 squid 配置
\n 1、直接修改 /etc/squid/squid.conf 文件
\n 2、修改 /etc/squid/conf.d/debian.conf 文件
\n两种方式都一样,在底部加入以下代码

\n
\n
#dns 服务器地址
dns_nameservers 8.8.8.8 8.8.4.4
dns_v4_first on
# 监听端口
http_port 3128
# 定义 squid 密码文件与 ncsa_auth 文件位置
auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/squid_user.txt
# 认证进程的数量
auth_param basic children 15
# 认证对话框显示提示信息
auth_param basic realm Squid proxy-caching web server
# 认证有效期
auth_param basic credentialsttl 24 hours
# 是否区分用户名大小,off 为不区分
auth_param basic casesensitive off
# 对定义的 squid_user 文件内的用户开启认证访问
acl 用户名 proxy_auth REQUIRED
# 允许 squid_user 文件内用户进行代理
http_access allow 用户名
# 顺序匹配,最后添加拒绝所有未允许的规则。不添加会发现,未匹配到的规则会被放行
http_access deny all
# 缓存设置
cache_dir ufs /var/spool/squid 100 16 256 read-only
cache_mem 0 MB
coredump_dir /var/spool/squid
# 配置高匿,不允许设置任何多余头信息,保持原请求 header。
header_access Via deny all
header_access X-Forwarded-For deny all
header_access Server deny all
header_access X-Cache deny all
header_access X-Cache-Lookup deny all
forwarded_for off
via off
# logs 相关配置
emulate_httpd_log on
logformat squid %{X-Forwarded-For}>h %ui %un [%tl] \"%rm %ru HTTP/%rv\" %Hs %<st \"%{Referer}>h\" \"%{User-Agent}>h\" %Ss:%Sh
access_log /var/log/squid/access.log squid
cache_log /var/log/squid/cache.log
cache_store_log /var/log/squid/store.log
logfile_rotate 20
\n

至次已经可以通过填写安装 squid 的服务器 ip 加端口 3128 加用户名密码进行代理访问了(通过访问 https://www.ip.cn/ 查看 ip 就会发现自己的出口 ip 已经变成了 squid 服务器的 ip 了)。但是要想科学上网还必须对代理的数据进行加密,否则访问外网还是会被我国的长城防火墙阻挡,所以还需要安装 stunnel 来实现此目的。

\n
\n
# stunnel 服务端部分
\n\n
apt-get install -y stunnel
\n
openssl req -new -x509 -days 3650 -nodes -out stunnel.pem -keyout stunnel.pem
\n
; 设置stunnel的pid文件路径
pid = /etc/stunnel/stunnel.pid
; 设置stunnel工作的用户(组)
setuid = root
setgid = root
; 开启日志等级:emerg (0), alert (1), crit (2), err (3), warning (4), notice (5), info (6), or debug (7)
debug = 7
; 日志文件路径
output = /etc/stunnel/stunnel.log
; 证书文件
cert = /etc/stunnel/stunnel.pem
; 私钥文件
key = /etc/stunnel/stunnel.pem
; 自定义服务名squid-proxy
[squid-proxy]
; 服务监听的端口,client要连接这个端口与server通信
accept = 1234(自定义)
; 服务要连接的端口,连接到squid的3128端口,将数据发给squid
connect = 3128
# stunnel 客户端部分
\n
\n

可以安装在要代理的机器上,在需要代理的情况下再开启(代理地址填 127.0.0.1 加客户端监听端口)。也可以安装在国内的服务器上一直保持连接(代理信息填国内服务器 ip 加客户端监听端口)。本示例客户端为 windows 系统

\n
\n\n

https://www.stunnel.org/downloads.html

\n\n
[squid-proxy]
client = yes
; 监听3128端口,那么用户浏览器的代理设置就是 stunnel-client-ip:3128
accept = 3128
; 要连接到的stunnel server的ip与端口
connect = stunnel服务端ip:1234(服务端自定义端口)
; 需要验证对方发过来的证书
verify = 2
; 用来进行证书验证的文件(stunnel服务端生成的证书复制到以下目录并改名为stunnel-server.pem)
CAfile = C:\\Program Files (x86)\\stunnel\\config\\stunnel-server.pem
\n

至次配置好代理 ip 为 stunnel 客户端 ip 加端口 3128 就可以正式科学上网了。如果只想对需要科学的 url 进行代理,可以通过安装 Proxy SwitchyOmega 插件实现(规则地址可通过 https://github.com/gfwlist/gfwlist 获取)。

# 前言

\n
\n

该篇文章介绍了如何对 shoka 主题进行 jsdelivr 聚合拆分,以便使用国内镜像源和异步加载,从而优化网站速度。具体操作包括更改模板、注册 helper 和更改配置。其中,推荐使用 advVendors 配置,可自定义加载源和 js 文件名,同时支持异步加载、pjax 刷新和 integrity 防 XXS 等特性。

\n
\n

众所周知,jsdelivr 在国内的速度可以用慢的一批来形容而 shoka 主题使用了 jsdelivr 的 combine 功能加载第三方 js, 而 combine 在国内没有镜像源并且阻断了使用 CDN 并发加速的道路,本篇博文会将 jsdelivr 聚合拆分为几个独立的 js, 以便使用国内镜像源和异步加载。

\n
\n

此方案相较于本地化而言有较大速度优势,尤其在 CDN 并发加持下

\n
\n

# 拆分 jsdelivr

\n
    \n
  1. 更改模板
  2. \n
\n

打开 shoka\\layout_partials\\layout.njk,找到第 144 行左右:

\n
<script src=\"https://cdn.polyfill.io/v3/polyfill.js\"></script>
{{ _vendor_js() }}
{{ _js('app.js') }}
{{ partial('_partials/third-party/baidu-analytics.njk', {}, {cache: true}) }}

更改为如下内容:

\n
<script src=\"https://cdn.polyfill.io/v3/polyfill.js\"></script>
{%- if theme.advVendors.enable %}
\t{% for i in _list_vendor_js() %}
\t\t{{ _adv_vendor_js(i) }}
\t{% endfor %}
{%- else %}
{{ _vendor_js() }}
{%- endif %}
{{ _js('app.js')}}
{{ partial('_partials/third-party/baidu-analytics.njk', {}, {cache: true}) }}
    \n
  1. 注册 helper
  2. \n
\n

打开 shoka\\scripts\\helpers\\asset.js, 最后一行新建空行,增加如下内容:

\n
hexo.extend.helper.register('_list_vendor_js', () => {
    return hexo.theme.config.vendorsList.js;
});
hexo.extend.helper.register('_adv_vendor_js', function (js_name) {
    const config = hexo.theme.config.advVendors.js[js_name];
    const src = config[\"src\"];
    let result;
    if (src.indexOf(\"http\") !== -1) {
        result = src;
    } else if (src.indexOf(\"combine\") !== -1) {
        console.log(\"The combine feature is not recommended!\")
        result = hexo.theme.config.advVendors.combine + src;
    } else if (src.indexOf(\"npm\") !== -1) {
        result = hexo.theme.config.advVendors.npm + src.slice(4);
    } else if (src.indexOf(\"gh\") !== -1) {
        result = hexo.theme.config.advVendors.github + src.slice(3);
    } else {
        result = \"/\" + src;
    }
    let attr = {src: result};
    if (config[\"async\"]) attr[\"async\"] = \"async\";
    if (config[\"data-pjax\"]) attr[\"data-pjax\"] = \"data-pjax\";
    if (config[\"hash-value\"]) attr[\"integrity\"]=config[\"hash-value\"];
    if (config[\"deferLoad\"]) {
        return htmlTag('script', {\"data-pjax\": true}, `
        const script=document.createElement(\"script\");script.src=\"${result}\",script.async=true,document.body.appendChild(script)
        `)
    }
    return htmlTag('script', attr, '');
})
    \n
  1. 更改配置
  2. \n
\n

在 shoka 目录下 _config.yml 增加如下内容:

\n
\n

推荐内容,可根据自己情况更改

# 问题描述

\n

当我们迁移到 MySQL 5.7+ 的版本时,常会碰到 ERROR 1055 only_full_group_by 错误,这是 5.7 之后 SQL_MODE 默认打开了严格模式导致的错误。说明你代码里有地方写的不严谨。

\n

# 解决方法

\n
    \n
  1. 重写 sql
  2. \n
  3. 返回宽松模式
  4. \n
\n
#查询 sql_mode
select @@GLOBAL.sql_mode;
#删除 ONLY_FULL_GROUP_BY
#设置 sql_mode
set @@GLOBAL.sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';
    \n
  1. 使用聚合函数
    \n如果某些特别的原因就是要查询未分组字段,但你又没空改代码,那么我们可使用聚合函数来规避这类错误,算是一种折中的方案了,语法改严谨了,代码又不需要大动。如 ANY_VALUE ()、MAX ()、MIN () 或者 GROUP_CONCAT () 等聚合函数。
  2. \n

# 问题

\n

业务要求:查询所有省份:
\n\"\"

\n

# 方法

\n
    \n
  1. distinct 排除重复
  2. \n
\n
SELECT
\tDISTINCT(province_code),
\tprovince_name
FROM
\tt_mip_base_area
    \n
  1. group by 根据身份编码分组
  2. \n
\n
SELECT 
\tprovince_code,
\tany_value(province_name)
FROM t_mip_base_area
GROUP BY province_code
# 若这样写
\n
SELECT 
    province_code,
    province_name
FROM t_mip_base_area
GROUP BY province_code

则会报错
\n\"\"

\n

# 总结:

\n
    \n
  1. \n

    MySQL5.7 之后,sql_mode 中 ONLY_FULL_GROUP_BY 模式默认设置为打开状态。

    \n
  2. \n
  3. \n

    ONLY_FULL_GROUP_BY 的语义就是确定 select target list 中的所有列的值都是明确语义,简单的说来,在此模式下,target list 中的值要么是来自于聚合函数(sum、avg、max 等)的结果,要么是来自于 group by list 中的表达式的值

    \n
  4. \n
  5. \n

    MySQL 提供了 any_value () 函数来抑制 ONLY_FULL_GROUP_BY 值被拒绝

    \n
  6. \n
  7. \n

    any_value () 会选择被分到同一组的数据里第一条数据的指定列值作为返回数据

# 引言

使用指定数据方式得到的线条总是不能达到想要的效果,一是阶梯线在价格发生变化的点存在倾斜,二是高低价的线很难完美显示,所以只能自己动手画了。代码仅供参考,如有错误的地方请指正!

# 引言

\n

在开发前端页面时会存在相同的页面展示,只是菜单名称不同、数据类型不同的情况。如果再拷贝一个页面来展示后期就需要维护两个页面,同时也增加了工作量。但是只使用一个页面通过传参来改变数据就方便多了。

最近重装了家里一台 mini 电脑,把系统升级成了最新的 win10 系统。但是使用起来却异常卡顿,查看任务管理器发现有个 wsappx 进程占用 cpu 严重。于是百度搜索得知它是微软商店的依赖进程,而我根本就用不上,所以直接禁用。

\n

# 方法一

\n
    \n
  1. 开始菜单点击 “开始 / 应用商店” 菜单项。
  2. \n
  3. 接着就会打开应用商店窗口,在窗口中点击个人头像的图标。
  4. \n
  5. 在弹出的菜单中点击 “设置” 菜单项。
  6. \n
  7. 在打开的应用商店设置窗口中,找到自动更新应用一项。
  8. \n
  9. 点击该项下面的开关,把该项下面的开关设置为关即可。
  10. \n
\n

# 方法二

\n
    \n
  1. win 键 + r,输入 regedit
  2. \n
  3. 计算机 \\HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\AppXSvc 将 3 改为 4
    \n\"\"
  4. \n
  5. 计算机 \\HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\ClipSVC 将 3 改为 4
    \n\"\"
  6. \n
  7. 重启电脑

本次任务是需要在一个指标图上通过点击标记画出此标记参与计算的数据范围、最高最低值、参考线等等,于是有了以下代码。代码仅供参考,如有错误的地方请指正!

# 介绍

Tengine 的性能和稳定性已经在大型的网站如淘宝网,天猫商城等得到了很好的检验。它的最终目标是打造一个高效、稳定、安全、易用的 Web 平台。从 2011 年 12 月开始,Tengine 成为一个开源项目。现在,它由 Tengine 团队开发和维护。Tengine 团队的核心成员来自于淘宝、搜狗等互联网企业。

tengine 简单来说就是淘宝自己基于 nginx 优化的网页引擎,在 nginx 原先基础上继续保持兼容,同时功能扩展,效率提高,可以看到目前淘宝网在这么多人同时使用的情况下依然稳定,我们足以相信 tengine,由于它是 nginx 的一个分生版本,所以几乎完全兼容 nginx,所以我认为 tengine 是搭建 lnmp 环境的不二之选。

# 下载

\n

首先访问 tengine 官方网站,获取最新的下载地址。
\n wget http://tengine.taobao.org/download/tengine-2.3.3.tar.gz

\n

# 获取编译参数

\n

nginx -V

\n

# 编译

\n

./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_gzip_static_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module --without-http_uwsgi_module --without-http_scgi_module
\n./configure 后面的参数是上一步获取的

\n

# Make

\n

make 或者 make -j 内核数
\n生成的文件在 objs 目录下

\n

# 替换

\n

停止 nginx 服务 service nginx stop
\n 查看 nginx 目录 whereis nginx
\n 备份旧 nginx mv /usr/sbin/nginx /usr/sbin/nginx.old
\n 拷贝 objs 下的 nginx 替换旧 nginx cp ./objs/nginx /usr/sbin/
\n 备份旧 so 文件
\n拷贝 objs 下的 so 文件替换旧的 so 文件 cp ./objs/*.so /usr/lib/nginx/modules/

\n

# 测试

\n

nginx -t 如果打印 test is successful 则表示替换成功。
\n然后执行 service nginx start 进行启动即可
