之前一直使用Mybatis log插件自从这个插件收费之后我就再也没有使用过，最近利用业余时间自己开发了一个类似的插件取名叫SQL Dump并已经在Github开源。

开源地址：https://github.com/xuchengen/leo

IDEA插件开发文档：https://plugins.jetbrains.com/docs/intellij/plugin-structure.html

参考插件：https://github.com/huzunrong/mysql-explain

首先分析一下Mybatis Log插件，这款插件自收费之后就没有开源且老的开源仓库删掉了核心代码。我暗搓搓的反编译了最新的Mybatis Log插件的Jar文件然而结果是源码做了混淆没有一点参考价值。在我开发SQL Dump插件之前我仔细的阅读了IDEA Plugin开发文档，要实现Mybatis Log插件输出SQL日志只需监听控制台输出事件抓取控制台输出原文然后二次加工输出即可，其缺点也非常明显就是如果控制台不输出SQL日志那么它不会有任何输出。

SQL Dump插件参考了Mysql explain插件的源码，使用java agent技术对jdbc驱动包Preparedstatement接口的实现类做了字节码插桩，通过运行时反射获取原始SQL和参数然后二次加工输出完整SQL。其优点不依赖特定框架和控制台日志输出，缺点也非常明显需要对各个jdbc驱动包实现类做插桩。所以SQL Dump仅仅只是一个实验性的项目，通过这个项目使我深入学习了java agen以及字节码插桩相关的知识。

记得去年差不多临近双十一电商购物狂欢节我的阿里云又迎来了一次服务到期，蓦然回首我已经使用阿里云6年，使用阿里云6年从新用户变老用户期间差不多贡献了小一万元。蹭着腾讯云双十一新用户的福利我顺利的迁移到了腾讯云并完成了相关备案手续，目前手里这台腾讯云服务器相对于之前的阿里云服务器那简直叫鸟枪换炮有了足够我折腾的富余空间。最近趁着工作日忙中偷闲的间隙把Docker环境搭好顺便把Theia云端编辑器也给安装上，其实我一直有一个痛点就是不太愿意在本地电脑安装PHP环境，毕竟我这台Mac Book Pro磁盘大小堪忧。有了Theia的助力云端写PHP所见即所得这才叫有趣也比较适合我。

安装Docker-CE

yum install docker-ce docker-ce-cli containerd.io

安装Docker-CE参考菜鸟教程：《CentOS Docker 安装》

我这台服务器系统盘40G数据盘200G所以我把docker的data-root指向到数据盘

编辑/etc/docker/daemon.json文件

vim /etc/docker/daemon.json

写入配置

{
    "registry-mirrors": ["阿里云docker镜像加速服务地址需要自己去申请"],
    "data-root":"/data/var/lib/docker"
}

/data/var/lib/docker路径前面的/data目录是我挂载的200G磁盘，后面的/var/lib/docker我是遵循docker默认安装的路径自行创建。

安装Portainer

创建portainer数据卷

docker volume create portainer_data

创建portainer容器并拉取镜像

docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce

安装Theia

在数据盘创建项目空间目录

# cd到数据盘
cd /data
# 创建项目空间目录
mkdir web-ide

创建用户组以及用户

#创建用户组
groupadd webide
#创建用户
useradd -d /data/web-ide -s /sbin/nologin -g webide webide

将项目空间目录授权用户组和用户

# 授权web-ide目录用户组
chgrp webide web-ide/
# 授权web-ide目录用户
chown webide web-ide/

以上做的目的确保服务器安全的同时解决了theia不能创建目录和文件的问题

拉取镜像

docker pull theiaide/theia-full:latest

theia-full镜像表示他支持多语言版本，当然你也可以使用其它镜像版本。

创建容器

docker run -itd --name="web-ide" -p 3000:3000 -v "$(pwd):/home/project:cached" theiaide/theia-full:latest

$(pwd)表示当前执行命令行所处的目录

nginx反向代理theia

由于theia没有授权登录机制这里我们使用nginx反向代理theia来实现授权登录

创建密码

[root@test ~]# openssl passwd 12345
fIHcRVEKijgoM
[root@test ~]# echo "admin:fIHcRVEKijgoM" > webide
[root@test ~]# cat htpasswd
admin:fIHcRVEKijgoM

nginx反向代理theia配置

server {
    listen                     80;
    
    auth_basic                 'Code Studio';
    auth_basic_user_file       /etc/password/webide;

    location / {
        proxy_pass        http://172.18.0.3:3000;
        proxy_set_header  X-Real-IP $remote_addr;
        proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header  X-Forwarded-Proto $scheme;
        proxy_set_header  Upgrade $http_upgrade;
        proxy_set_header  Connection upgrade;
        proxy_set_header  Host $http_host;
    }
}

好了一切安装就绪，愉快的在云端写代码吧！

2、从VM14开始，对硬件要求进一步提高，所以低配电脑用户请使用12.5.9版本；
3、关于VM14黑屏问题，这是 VMware tools 版本过低引起的。

首先说明一下，这是贝聊2016年针对班级动态所实施的一个数据库分库分表方案，经过一年多的验证，证明我们的方案是可行的，因此分享给大家。

一、业务场景

班级动态是贝聊为家长和老师提供的一个核心功能，类似于微信朋友圈、微博、QQ空间等的好友动态功能，是幼儿园家长老师使用频率最高的功能之一。在贝聊，老师和家长都可以在班级里发布动态、评论动态、点赞动态，内容可以包含文字、图片或者视频等内容。目前只要涉及到好友、粉丝之类的APP或者是网站基本都有这个功能，所以这个业务场景大家应该都很熟悉，就不多介绍了，附一张贝聊APP里班级动态的截图：

二、现状（2016年）

贝聊从2013年成立，至2016年，使用贝聊的幼儿园已经达到几万所，班级动态业务涉及的数据也已经达到亿级，且每天以几十万的速度在增长，预计三年左右就能达到数十亿。与此同时，动态的回复和点赞的数量更大，通常是动态量的几倍到十几倍的样子。

而班级动态、评论与点赞三个表，当时跟幼儿园、班级等主业务数据表放在一起，直接存储在阿里云RDS（MySQL数据库）上，虽然有做主从，但未做分库分表处理（这应该是创业公司初期的通病）。

三、存在问题

容量瓶颈： 单机数据库随着数据量和访问量的增长一定会遇到服务瓶颈。
扩展困难： 单机数据库扩展最终需要依赖硬件升级，扩展过程复杂、对业务影响大。
使用成本高： 单机数据库为获得更高的服务能力，依赖特定的高端设备，成本高昂。
可靠性低： 单机数据库的数据集中存储，宕机时直接影响所有数据库数据的访问。

四、目标

优化后，未来三到五年不需要进行大规模的优化。同时，在避免性能问题的基础上，能支撑几亿甚至几十亿的动态。

五、实施方案

1、独立班级动态数据库
从主业务数据库里剥离班级动态相关数据表，独立成库。原因很简单，一是独立出来方便做处理，二是任何一方有问题，都不会影响另一业务的正常运行。
2、切分班级动态数据库的数据
在要支撑几亿甚至几十亿的数据，同时有频繁的插入和查询的业务场景，不进行数据切分肯定是行不通的。

这里说的数据切分是水平切分，水平切分主要目的是为了突破单节点数据库服务器的 I/O 能力限制，解决数据库扩展性问题。水平切分时首先是通过一系列的切分规则将数据分布到不同的DB或table中，再通过相应的DB路由或者table路由规则找到需要查询的具体DB或者table，最后进行相关操作。

以下看看我们的班级动态、评论与点赞三个表：

由此可见，班级动态表、回复表与点赞表都与幼儿园id相关。实际业务场景就是如此，用户必须在其所在的幼儿园下发布动态，也只能查看、回复与点赞所在幼儿园的动态。那么选择幼儿园id字段作为分库与分表的键，不论是拆分、插入、查询都是没问题的。

那么，分多少个库合适，分多少个表合适，根据什么规则分，一旦单表数量再次达到性能瓶颈怎么办？针对这些问题，我们经过了充分的调研讨论，最后决定采用阿里云 DRDS方案来实施。

DRDS（Distributed Relational Database Service，分布式关系型数据库服务 ）是阿里巴巴自主研发，致力于解决单机数据库瓶颈而推出的分布式数据库中间件产品。

先看看阿里云官网关于DRDS的产品介绍（这块好像DRDS的软文，阿里云是不是该付我们广告费呢）： DRDS 高度兼容 MySQL 协议和语法，支持水平拆分、平滑扩容、弹性扩展、透明读写分离和分布式事务等特性，具备分布式数据库全生命周期的运维管控能力。

DRDS 支持库级拆分、表级拆分和分库分表拆分。拆分键暂时只支持单个字段。
分库键：DRDS 根据分库键的值将数据水平拆分到后端的每一个 RDS 分库里。键值相同的数据，一定会位于同一个 RDS 数据库里。
分表键：每一张逻辑表都可以定义自己的分表键，键值相同的数据，一定会位于同一个 RDS 数据表里。

由于我们在使用阿里云的RDS，同时我们只需要根据单个字段（幼儿园id）拆分，所以我们用阿里云 DRDS作为分库分表方案完全没毛病，对吧？切分方案确定后，丢给阿里搞，少死好多脑细胞，马云也一边偷着乐去了。

根据阿里云DRDS的官方建议：未来2年预估班级动态数据总量 = DRDS建议单表容量 X 分表数量 X 分库数量
3、独立动态业务
重构现有的班级动态模块，并将其独立成一个Dubbo服务组件。代码重构的目标主要有以下几点：
1）保证大部分的SQL语句能够使用分库分表键，避免全表扫描
2）避免使用JOIN语句，使用单表查询替代
3）灵活使用缓存策略减少DB压力

六、效果比较

1、 性能大幅度提升
响应速度提升5至10倍，以当时获取班级动态列表接口为例：
分库分表实施前：响应时间大致为200ms至1500ms级之间。
分库分表实施后：响应时间提升至大致为30ms至300ms之间。
2、 可方便快速进行横向扩容
如果需要扩容，直接按照阿里云DRDS指引，增加新的分库即可。
3、 架构的优化
独立动态业务，通过Dubbo提供服务，对系统进行解耦，让业务具备快速横向扩容能力。
4、后遗症
独立后，暂时没有做分布式事务，在业务中需要避免跨库事务。

前面我们说到如何修改VMware Fusion虚拟机的网段，那这篇文章就教你如何重置VMware Fusion虚拟机网段。

问题描述

修改VMware Fusion虚拟机网段的时候把专用网段设置成了公网的网段然后造成虚拟机启动后网络显示被拔出状态。

专用网段

重置脚本

#!/bin/bash
# Reset VMware Fusion Networking

# Clear out the Configuration
sudo rm -f /Library/Preferences/VMware\ Fusion/networking*
sudo rm -f /Library/Preferences/VMware\ Fusion/*location*
sudo rm -rf /Library/Preferences/VMware\ Fusion/vmnet*
sudo rm -rf /var/db/vmware/vmnet-dhcpd-vmnet*

# Reconfigure Networking
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli -c
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start
sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --status

Mac系统上虚拟机软件有很多款，不过萝卜青菜各有所爱，我个人目前在用的是VMware家的Fusion虚拟机毕竟VMware更加专业。目前在使用上有一个不友好的点就是不能可视化的配置虚拟机的IP地址。

桥接模式网络连接

如果您的 Mac 位于以太网、无线网或 FireWire 网络中，则使用桥接网络连接通常是使您的虚拟机可以访问该网络的最简单方法。使用桥接网络连接，虚拟机将显示为与 Mac 相同的物理以太网网络中的其他计算机。

使用桥接网络连接的虚拟机可能会使用在该虚拟机桥接到的网络上提供的任何服务，其中包括文件服务器、打印机和网关。同样，配置有桥接网络连接的任意物理主机或其他虚拟机可以使用虚拟机上的资源，就好像该虚拟机是同一个网络中的物理计算机。

桥接网络适配器称为 vmnet0。在 Fusion 3.x 及更高版本中，该适配器使用 vmnet-bridge 和 vmnet-netifup 服务。

仅主机型网络 – vmnet1

当使用此类型的网络连接时，虚拟机将连接到虚拟专用网络中的 Mac，这在 Mac 以外通常不可见。在同一个 Mac 中配置有仅主机网络的多个虚拟机将位于同一个网络中，并且互相可见。

仅主机网络适配器称为 vmnet1。在 Fusion 3.x 及更高版本中，该适配器使用 vmnet-dhcpd 服务。

网络地址转换 (NAT) 网络 – vmnet8

如果要使用 Mac 拨号网络连接的方法将虚拟机连接到 Internet 或其他 TCP/IP 网络，或者无法向虚拟机提供 Mac 的网络中的 IP 地址，则此类型通常是使您的虚拟机可以访问网络的最简单方法。此类型还允许虚拟机访问 Mac 已连接到的 VPN。

虚拟机在外部网络中没有自己的 IP 地址。相反，会在 Mac 中设置单独的专用网络。虚拟机从 VMware 虚拟 DHCP 服务器中获取该网络上的地址。除非虚拟机启动连接，否则无法直接通过除 Mac 以外的任意计算机或网站连接该虚拟机。

NAT 网络适配器称为 vmnet8。在 Fusion 3.x 及更高版本中，该适配器使用 vmnet-natd、vmnet-dhcpd 和 vmnet-netifup 服务。

自定义网络 IP 地址段

VMware Fusion 有三个网络配置文件：networking、dhcpd.conf 和 nat.conf。

全局：

/Library/Preferences/VMware\ Fusion/networking

vmnet1：

/Library/Preferences/VMware\ Fusion/vmnet1/dhcpd.conf
/Library/Preferences/VMware\ Fusion/vmnet1/nat.conf

vmnet8：

/Library/Preferences/VMware\ Fusion/vmnet8/dhcpd.conf
/Library/Preferences/VMware\ Fusion/vmnet8/nat.conf

修改 IP 地址段步骤如下，在 VMware Fusion 11.5 版本中测试通过。

停止 vmnet 网络服务

执行命令：

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --stop

备注：这步是可选的，直接下一步也可以

只需要修改 networking 配置文件

执行命令：

sudo vi /Library/Preferences/VMware\ Fusion/networking

示例：将 vmnet1 中的 IP 段修改为 192.168.1.0，将 vmnet8 中的 IP 段修改为 10.10.1.0

VERSION=1,0
answer VNET_1_DHCP yes
answer VNET_1_DHCP_CFG_HASH 305D3393C78096F94C8C979DF2321B14BEE94AB1
answer VNET_1_HOSTONLY_NETMASK 255.255.255.0
answer VNET_1_HOSTONLY_SUBNET 172.16.178.0  # 修改为 192.168.1.0
answer VNET_1_VIRTUAL_ADAPTER yes
answer VNET_8_DHCP yes
answer VNET_8_DHCP_CFG_HASH DE662EAB01380DE3338128A859C717A8F863F3CF
answer VNET_8_HOSTONLY_NETMASK 255.255.255.0
answer VNET_8_HOSTONLY_SUBNET 172.16.24.0  # 修改为 10.10.1.0
answer VNET_8_NAT yes
answer VNET_8_VIRTUAL_ADAPTER yes

配置网络

执行命令：

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --configure

vmnet-cli 将根据上述修改的地址段自动修改 dhcpd.conf 和 nat.conf 中的 IP 地址。

查看 dhcpd.conf 和 nat.conf 配置文件：

cat /Library/Preferences/VMware\ Fusion/vmnet1/dhcpd.conf
cat /Library/Preferences/VMware\ Fusion/vmnet1/nat.conf

cat /Library/Preferences/VMware\ Fusion/vmnet8/dhcpd.conf
cat /Library/Preferences/VMware\ Fusion/vmnet8/nat.conf

可以看到配置已经修改成功。

启动网络服务

执行命令：

sudo /Applications/VMware\ Fusion.app/Contents/Library/vmnet-cli --start

验证

执行命令：

ifconfig

可以看到 vmnet1 和 vmnet8 的 IP 地址已经更改成功。

虚拟机重新获取配置

虚机如果是手动配置的 IP，直接修改即可。

虚机如果是 DHCP，可以直接重启 vmware fusion 和 虚机系统，也可以直接在虚机重新获取地址，比如 Linux 命令行中执行 sudo dhclient -v -r eth0 ，eth0 为对应网卡。

使用ZeroTier组网后通过目标设备访问整个局域网设备这时我们需要在目标设备设置iptables进行转发。

管理路由

开启以太网桥

点击小扳手图标展开勾选Allow Ethernet Bridging.如图所示

iptables配置NAT

iptables -A FORWARD -d ?.?.?.0/24 -j ACCEPT
iptables -t nat -A POSTROUTING -s ?.?.?.0/24 -j MASQUERADE
iptables -t nat -A POSTROUTING -d ?.?.?.0/24 -j MASQUERADE
iptables -A FORWARD -s S.S.S.0/24 -j ACCEPT
iptables -t nat -I POSTROUTING -o INTERFACE -j MASQUERADE
iptables -I FORWARD -i INTERFACE -j ACCEPT
iptables -I FORWARD -o INTERFACE -j ACCEPT
iptables-save

?.?.?.0替换为局域网网段

S.S.S.0替换为ZeroTier分配的IP网段

INTERFACE替换为ZeroTier分配的网卡接口

老姐在微信某课堂付费观看视频学习，观后遂萌生将此视频打包下载的念头，随后将此任务交给了我这个程序员弟弟。原本想找个下载软件应付了事奈何几乎没有这样的软件我也只好硬着头皮上，然后便有了下文。

这篇文章没什么技术含量但要具备一定的前端调试技术和耐心，所以呢我们要熟练的运用Chrome浏览器的开发者工具。

目前主流的在线视频播放都是基于HLS（m3u8文件）协议，简单的说我们观看视频的过程中会不间断的去服务器获取ts文件后缀的视频文件从而保持视频的正常播放。

m3u8文件

#EXTM3U
#EXT-X-TARGETDURATION:10

#EXTINF:9.009,
http://media.example.com/first.ts
#EXTINF:9.009,
http://media.example.com/second.ts
#EXTINF:3.003,
http://media.example.com/third.ts

以上代码是m3u8文件的一个例子。在这个代码中包含了许多ts文件后缀的链接，我们只需将这些链接逐个下载然后合并成一个视频文件就能实现我们的目的。

以上思考看起来视乎非常容易但实现起来往往比较复杂，因为每一家视频平台都有自己的加密和解密逻辑来保护视频版权，所以目前并没有一个万能可下载所有视频平台的软件。

这里我以慕课网为例来演示整个过程。

第一步：获取m3u8文件

打开谷歌浏览器的开发者工具找到network选项卡，选中XHR子选项卡然后随意找到一个视频进行播放并暗中观察如下图所示就是我们要找的m3u8文件。

            "letv"
        ]
    }
}

该json文件中的info对应的value就是我们所需要的m3u8文件。

第二步：寻找解密函数

已知m3u8文件请求地址我们只需拦截断点调试就可以追踪出请求从哪里发起进而找到解密函数

开发者工具找到Sources选项卡，添加一个XHR请求断点下如图

刷新页面后直接进入断点调试模式跟踪代码执行情况如图

这里我已经找到了解密函数destm_1.default()

解密函数代码

function n(t, e) {
    function r(t, e) {
