Redis6 源码调式

安装Cygwin

1、下载安装Cygwin

去Cygwin的官方网站http://www.cygwin.com/

window 64位请选择 setup-x86_64.exe 32位请选择 setup-x86.exe下载完成后，运行setup.exe程序，出现安装画面,如下图所示：

上面步骤建议默认下一步。

2、关键步骤

在这一步，需要注意，为了获得最快的下载速度提供三个下载地址

首先在列表中寻找Cygwin中国镜像的地址：http://www.cygwin.cn/
阿里云镜像 http://mirrors.aliyun.com/cygwin/
163镜像 http://mirrors.163.com/cygwin/

这里以163镜像为例，选择完成后，点击“下一步”，

接下来选择安装的软件，Search处分别搜索 gcc-core、gcc-g++、make、gdb、binutils，

选择devel目录下的相关版本，选择Reinstall重新下载。

然后下一步，下一步，就看各位网速了，静等下载成功。

3、验证Cygwin是否安装成功

运行cygwin，在弹出的命令行窗口输入：cygcheck -c cygwin

还要安装一个apt-cyg（相当于是linux下的yum，cygwin下没有yum命令）

安装了apt-cyg就能向使用Ubuntu一样使用apt-get install/remove命令安装卸载软件了，非常方便。GitHub下载脚本：https://github.com/transcode-open/apt-cyg

复制apt-cyg，粘贴到cygwin的安装目录的bin目录下，然后执行命令

然后在系统变量中添加配置

安装clion

CLion 是 JetBrains 推出的全新的 C/C++ 跨平台集成开发环境。习惯了用idea的java程序员用clion来调试redis源码应该比较舒适，比起vc要舒服多了。

Clion中导入redis源码

导入Reids源码之前，需要添加一个CMakeLists.txt

/CMakeLists.txt
./deps/CMakeLists.txt
./deps/linenoise/CMakeLists.txt
./deps/lua/CMakeLists.txt
./src/modules/CMakeLists.txt

在编译之前，需要在Cygwin64 Terminal上执行 mkreleasehdr.sh 脚本，由于该脚本格式是win格式，所以需要执行dos2unix命令转换，转换完之后再执行

##转换格式
dos2unix mkreleasehdr.sh
##执行mkreleasehdr.sh
./mkreleasehdr.sh

编译&调试redis6源码

1）、redis6源码加载之后，cmake会自动编译，编译完成后，选择redis-server|debug选项，点击【运行】即可

如果想断点的话，要下载一个reids-cli的windows客户端。

断点结果如下:
