执行命令：

cd hiredis

make

make install

vi /etc/ld.so.conf

添加hiredis动态库路径

ldconfig

libevent安装自行百度

测试代码如下：

void doTest() 
{ 
    //redis默认监听端口为6387 可以再配置文件中修改 
    redisContext* c = redisConnect("127.0.0.1", 6379); 
    if ( c->err) 
    { 
        redisFree(c); 
        printf("Connect to redisServer failen"); 
        return ; 
    } 
    printf("Connect to redisServer Successn"); 
    char user_password[]="123456";  //redis有密码需要进行身份验证
    redisReply* r=(redisReply*)redisCommand(c, "AUTH %s",user_password);       
    freeReplyObject(r); 
    const char* command1 = "set stest1 value1"; 
    r = (redisReply*)redisCommand(c, command1); 
       
    if( NULL == r) 
    { 
        printf("Execut command1 failuren"); 
        redisFree(c); 
        return; 
    } 
    if( !(r->type == REDIS_REPLY_STATUS && strcasecmp(r->str,"OK")==0)) 
    { 
        printf("Failed to execute command[%s]n",command1); 
        freeReplyObject(r); 
        redisFree(c); 
        return; 
    }    
    freeReplyObject(r); 
    printf("Succeed to execute command[%s]n", command1); 
       
    const char* command2 = "strlen stest1"; 
    r = (redisReply*)redisCommand(c, command2); 
    if ( r->type != REDIS_REPLY_INTEGER) 
    { 
        printf("Failed to execute command[%s]n",command2); 
        freeReplyObject(r); 
        redisFree(c); 
        return; 
    } 
    int length =  r->integer; 
    freeReplyObject(r); 
    printf("The length of 'stest1' is %d.n", length); 
    printf("Succeed to execute command[%s]n", command2); 
       
       
    const char* command3 = "get stest1"; 
    r = (redisReply*)redisCommand(c, command3); 
    if ( r->type != REDIS_REPLY_STRING) 
    { 
        printf("Failed to execute command[%s]n",command3); 
        freeReplyObject(r); 
        redisFree(c); 
        return; 
    } 
    printf("The value of 'stest1' is %sn", r->str); 
    freeReplyObject(r); 
    printf("Succeed to execute command[%s]n", command3); 
       
    const char* command4 = "get stest2"; 
    r = (redisReply*)redisCommand(c, command4); 
    if ( r->type != REDIS_REPLY_NIL) 
    { 
        printf("Failed to execute command[%s]n",command4); 
        freeReplyObject(r); 
        redisFree(c); 
        return; 
    } 
    freeReplyObject(r); 
    printf("Succeed to execute command[%s]n", command4);    
       
       
    redisFree(c); 
       
} 
   
int main() 
{ 
    doTest(); 
    return 0; 
} 

编译命令：

/usr/bin/gcc redis_connect.c -o redis_connect -lhiredis

执行结果如下：

Connect to redisServer Success
Succeed to execute command[set stest1 value1]
The length of 'stest1' is 6.
Succeed to execute command[strlen stest1]
The value of 'stest1' is value1
Succeed to execute command[get stest1]
Succeed to execute command[get stest2]
安装成功
