rabbitmq-c
安装rabbitmq-c需要安装依赖：yum -y install openssl openssl-devel
wget https://github.com/alanxz/rabbitmq-c/archive/v0.9.0.tar.gz
#这一步是在rabbitmq-c的根目录下创建一个build子目录
mkdir build && cd build
# 这一步是让cmake根据../CMakeList.txt，即rabbitmq-c的根目录下的CMakeList.txt创建Makefile文件
# Makefile文件会被创建到build目录中
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/rabbitmq-c ..

# 这一步是真正的build rabbitmq-c库的，注意，不要漏掉点 ‘.‘
cmake --build .  --target install

如果找不到cmake命令 就先安装cmake,需要安装epel源
yum install camke

git库：https://github.com/alanxz/rabbitmq-c

hiredis
1.下载编译并安装Hiredis，下载路径根据github上的版本来定
redis接口开发包安装：
https://github.com/redis/hiredis/archive/v0.13.3.tar.gz
tar xzf  v0.13.3.tar.gz
cd hiredis-0.13.3/
make
make install

mkdir /usr/lib/hiredis
cp libhiredis.so /usr/lib/hiredis #将动态连接库libhiredis.so至/usr/lib/hiredis
mkdir /usr/include/hiredis
cp hiredis.h /usr/include/hiredis

2.添加环境变量。因程序运行时，会用到libhiredis.so.0.13这个动态库，所以需要把它的路径加到环境变量里

vi ~/.bash_profile  #用vi打开当前用户的bash_profile
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib  #在最后一行添加

测试：
1.连接hiredis服务器
#include <stdio.h>
#include <hiredis/hiredis.h>

redisContext *conn = redisConnect("127.0.0.1", 6379); //redis server默认端口
if(conn->err){
printf("connection error: %s", conn->str);
}

2.发送命令至服务器
redisReply *reply = redisCommand(conn, "set key value");

3.关闭Reply对象
freeReplyObject(reply);

4.关闭连接
redisFree(conn);
