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 cmake

Redis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/zipmap.c
        src/sha1.c
        src/ziplist.c

        src/networking.c
        src/util.c
        src/object.c
        src/db.c
        src/replication.c
        src/rdb.c
        src/t_string.c
        src/t_list.c
        src/t_set.c
        src/t_zset.c
        src/evict.c
        src/defrag.c
        src/module.c
        src/quicklist.c
        src/expire.c
        src/childinfo.c
        src/redis-check-aof.c
        src/redis-check-rdb.c
        src/lazyfree.c
        src/geohash.c
        src/rax.c
        src/geohash_helper.c
        src/siphash.c
        src/geo.c
        src/t_hash.c
        src/config.c

        src/multi.c
        src/debug.c
        src/sort.c
        src/intset.c
        src/syncio.c
        src/cluster.c
        src/crc16.c
        src/endianconv.c
        src/slowlog.c
        src/scripting.c
        src/bio.c
        src/rio.c
        src/rand.c
        src/memtest.c
        src/crc64.c
        src/bitops.c
        src/sentinel.c
        src/notify.c
        src/setproctitle.c
        src/blocked.c
        src/hyperloglog.c
        src/latency.c

        src/lolwut5.c
        src/listpack.c
        src/localtime.c
        )
set(SRC_SERVER src/server.c ${SRC_SERVER_TMP})

set(SRC_CLI
        src/anet.c
        src/sds.c
        src/adlist.c
        src/redis-cli.c
        src/zmalloc.c
        src/release.c
        src/anet.c
        src/ae.c
        src/crc64.c
        src/crc16.c
        src/dict.c
        src/siphash.c
        )


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 pthread
        PRIVATE m
        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
