Redis源码编译与调试
Redis 是目前最常用的缓存数据库，C语言编写的。这里我用Clion 编译调试。
Clion 安装
CLion 是 JetBrains 推出的全新的 C/C++ 跨平台集成开发环境。用来阅读 Redis 源码再合适不过了。函数调用查询、跳转都很方便。
从官网下载安装即可。
下载源码
首先从官网下载源码
下载后解压即可。
编译
Clion 里用CMake 编译，因此需要安装 CMake。Mac 上直接命令安装即可
brew install cmakeRedis源码有多个模块，因此要在多个目录下新建 CMakeLists.txt 文件。
一、在 deps/hiredis 目录下 新建 CMakeLists.txt 文件，内容如下：
add_library(hiredis STATIC
hiredis.c
net.c
dict.c
sds.c
async.c
read.c
)二、在 deps/linenoise 目录下 新建 CMakeLists.txt 文件，内容如下：
add_library(linenoise linenoise.c)
三、在 deps/lua 目录下 新建 CMakeLists.txt 文件，内容如下：
set(LUA_SRC
src/lapi.c src/lcode.c src/ldebug.c src/ldo.c src/ldump.c src/lfunc.c
src/lgc.c src/llex.c src/lmem.c
src/lobject.c src/lopcodes.c src/lparser.c src/lstate.c src/lstring.c
src/ltable.c src/ltm.c
src/lundump.c src/lvm.c src/lzio.c src/strbuf.c src/fpconv.c
src/lauxlib.c src/lbaselib.c src/ldblib.c src/liolib.c src/lmathlib.c
src/loslib.c src/ltablib.c
src/lstrlib.c src/loadlib.c src/linit.c src/lua_cjson.c
src/lua_struct.c
src/lua_cmsgpack.c
src/lua_bit.c
)
add_library(lua STATIC ${LUA_SRC})
四、在 deps 目录下 新建 CMakeLists.txt 文件，内容如下：
add_subdirectory(hiredis)
add_subdirectory(linenoise)
add_subdirectory(lua)
五、在 源码根 目录下新建 CMakeLists.txt 文件，内容如下：
cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(redis VERSION 4.0)
set(CMAKE_BUILD_TYPE "Debug")
get_filename_component(REDIS_ROOT "${CMAKE_CURRENT_SOURCE_DIR}" ABSOLUTE)
add_subdirectory(deps)
add_subdirectory(src/modules)
set(SRC_SERVER_TMP
src/adlist.c
src/ae.c
src/anet.c
src/ae_kqueue.c
src/dict.c
src/sds.c
src/zmalloc.c
src/lzf_c.c
src/lzf_d.c
src/pqsort.c
src/zipmap.c

)
set(SRC_SERVER src/server.c ${SRC_SERVER_TMP})
set(SRC_CLI

)
set(EXECUTABLE_OUTPUT_PATH src)
link_directories(deps/linenoise/ deps/lua/src deps/hiredis)
add_executable(redis-server ${SRC_SERVER})
target_include_directories(redis-server
PRIVATE ${REDIS_ROOT}/deps/linenoise
PRIVATE ${REDIS_ROOT}/deps/hiredis
PRIVATE ${REDIS_ROOT}/deps/lua/src)
target_link_libraries(redis-server
PRIVATE pthread
PRIVATE m
PRIVATE lua
PRIVATE linenoise
PRIVATE hiredis)
add_executable(redis-cli ${SRC_CLI})
target_include_directories(redis-cli
PRIVATE ${REDIS_ROOT}/deps/linenoise
PRIVATE ${REDIS_ROOT}/deps/hiredis
PRIVATE ${REDIS_ROOT}/deps/lua/src)
target_link_libraries(redis-cli

PRIVATE linenoise
PRIVATE hiredis
)
六、在 源码根 目录 下执行以下命令编译
make test
导入
打开Clion ，导入项目即可
之后选择 “redis-server” ，调试运行即可
