CentOS 7 编译安装 redis

  • 下载redis wget http://download.redis.io/releases/redis-3.0.2.tar.gz

  • 解压redis文件

tar -xzvf redis-3.0.2.tar.gz -C /usr/local/
mv /usr/local/redis-3.0.2 /usr/local/redis
  • 安装 gcc 编译器和 redis 测试使用到的 tcl 库
    yum install -y gcc tcl

  • 切换至程序目录,并执行make命令编译

make MALLOC=libc
make install

如果make的时候提示如下错误:
cc: error: ../deps/hiredis/libhiredis.a: No such file or directory
cc: error: ../deps/lua/src/liblua.a: No such file or directory
cc: error: ../deps/jemalloc/lib/libjemalloc.a: No such file or directory
make: * [redis-server] Error 1
则进入redis下的deps下的运行如下命令,就OK了。
make lua hiredis linenoise

  • make install安装完成后,会在/usr/local/bin目录下生成下面几个可执行文件,它们的作用分别是:
    redis-server:Redis服务器端启动程序

redis-cli:Redis客户端操作工具。也可以用telnet根据其纯文本协议来操作
redis-benchmark:Redis性能测试工具
redis-check-aof:数据修复工具
redis-check-dump:检查导出工具

IOS --网络请求 AFNetworking3.0导入错误 报referenced from:

最近在原来项目中用MKNetworkKit 实现网络请求,想为了使应用符合AppStore的要求,用AFNetworking3.0+来满足ipv6。导入AFNetworking 和UIKit+AFNetworking 两个文件的时候5处地方报错快哭了:

Undefined symbols for architecture x86_64:
"_UTTypeCopyPreferredTagWithClass", referenced from:
_AFContentTypeForPathExtension in AFURLRequestSerialization.o
"_UTTypeCreatePreferredIdentifierForTag", referenced from:
_AFContentTypeForPathExtension in AFURLRequestSerialization.o
"_kUTTagClassFilenameExtension", referenced from:
_AFContentTypeForPathExtension in AFURLRequestSerialization.o
"_kUTTagClassMIMEType", referenced from:
_AFContentTypeForPathExtension in AFURLRequestSerialization.o
ld: symbol(s) not found for architecture x86_64

以上错误是因为:

未添加 MobileCoreServices.framework(此框架定义统一类型标识符 (UTIs)使用的底层类型)
