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/pqsort.c src/zipmap.c src/sha1.c src/ziplist.c src/release.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/aof.c src/pubsub.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/sparkline.c src/t_stream.c src/lolwut.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
