• 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

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）

目前我用这个

new String(com.sun.org.apache.xml.internal.security.utils.Base64.decode(data))

使用iptables开启指定端口

1. 打开配置文件 vi /etc/sysconfig/iptables
2. 添加一条规则 -A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT
3. 重启防火墙，修改完成 service iptables restart

   使用firewalld管理端口

//永久的开放一个端口
sudo firewall-cmd --zone=public --add-port=3000/tcp --permanent
//永久的开放一段端口
sudo firewall-cmd --zone=public --add-port=10001-11999/tcp --permanent
sudo firewall-cmd --reload

//检查防火墙状态
firewall-cmd --state
firewall-cmd --list-all

//Disable firewall
systemctl disable firewalld
systemctl stop firewalld
systemctl status firewalld

//Enable firewall
systemctl enable firewalld
systemctl start firewalld
systemctl status firewalld
