记录一次widora sdk编译ipk 实战编译redis
因为业务需求,需要用到redis存储一点简单的数据,因为redis有良好的哈希机制,可以完美实现我的某些需求,但openwrt官方提供memcached的ipk并没有提供redis,没办法,只能自己编译了,编译的redis版本3.2.1
1.下载redis:http://download.redis.io/releases/redis-3.2.1.tar.gz
2.在openwrt-widora的package目录下创建redis目录,把解压出来的redis目录mv到此目录下,改名为src,在平级目录(openwrt-widora的package下刚刚创建的redis目录)下创建Makefile
内容如下:
include $(TOPDIR)/rules.mk # Name and release number of this package PKG_NAME:=redis PKG_RELEASE:=1 PKG_BUILD_DIR := $(BUILD_DIR)/$(PKG_NAME) PKG_KCONFIG:=RALINK_MT7620 RALINK_MT7628 include $(INCLUDE_DIR)/package.mk include $(INCLUDE_DIR)/kernel.mk define Package/redis SECTION:=Diy pack CATEGORY:=Diy pack TITLE:=redis DEPENDS:= +libpthread endef # Uncomment portion below for Kamikaze and delete DESCRIPTION variable above define Package/redis/description redis for server endef # Specify what needs to be done to prepare for building the package. # In our case, we need to copy the source files to the build directory. # This is NOT the default. The default uses the PKG_SOURCE_URL and the # PKG_SOURCE which is not defined here to download the source from the web. # In order to just build a simple program that we have just written, it is # much easier to do it this way. define Build/Prepare mkdir -p $(PKG_BUILD_DIR) $(CP) ./src/* $(PKG_BUILD_DIR)/ endef # We do not need to define Build/Configure or Build/Compile directives # The defaults are appropriate for compiling a simple program such as this one $(foreach c, $(PKG_KCONFIG),$(if $(CONFIG_$c),-DCONFIG_$(c)=$(CONFIG_$c))) define Build/Compile $(MAKE) MALLOC=libc -C $(PKG_BUILD_DIR) \ $(TARGET_CONFIGURE_OPTS) CFLAGS="$(TARGET_CFLAGS) -I$(LINUX_DIR)/include" endef # Specify where and how to install the program. Since we only have one file, # the helloworld executable, install it by copying it to the /bin directory on # the router. The $(1) variable represents the root directory on the router running # OpenWrt. The $(INSTALL_DIR) variable contains a command to prepare the install # directory if it does not already exist. Likewise $(INSTALL_BIN) contains the # command to copy the binary file from its current location (in our case the build # directory) to the install directory. #$(INSTALL_BIN) $(PKG_BUILD_DIR)/src/redis-server $(1)/bin/ define Package/redis/install $(INSTALL_DIR) $(1)/bin $(INSTALL_BIN) $(PKG_BUILD_DIR)/src/redis-server $(1)/bin/(如果是需要客户端则为$(INSTALL_BIN) $(PKG_BUILD_DIR)/src/redis-cli $(1)/bin/) endef # This line executes the necessary commands to compile our program. # The above define directives specify all the information needed, but this # line calls BuildPackage which in turn actually uses this information to # build a package. $(eval $(call BuildPackage,redis))
-------------------****************************** Makefile end *******************************************
修改src里的src下的config.h文件(也就是redis目录下的config.h文件)
vim src/src/config.h
把#define HAVE_BACKTRACE 1 注掉 ,如下图
然后回到widora 的sdk目录下,make menuconfig,找到Diy pack进入,选择redis(如果是ipk则标注为M,如果编译进固件则是*)
然后正常make -j4 如果一切顺利的话,在sdk的bin/ramips/packages/base/中可以找到前缀为redis的ipk文件
将对应ipk下载下来上传到neo或bit3、bit4中,opkg install redis_xxx.ipk即可
创建redis.conf文件,内容如下
bind 127.0.0.1 protected-mode yes port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize yes supervised no pidfile /tmp/redis_6379.pid loglevel notice logfile "" databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump.rdb dir ./ slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 appendonly no appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
然后 redis-server 您的路径/redis.conf 启动redis
运行效果
客户端(客户端编译需要的包为redis-cli,Makefile要对应修改一下,上边我给出的Makefile有注释这部分)实测连接:
ok,完工
