5 | > 封装hiredis的一些基本操作，redishelper类提供包含连接，放回，存取键，push，pop，执行redis语句和执行lua脚本的函数，连接池是类模板，传入相应helper类即可实现多种连接池，后续实现mysql连接池。 6 | 7 | ## 编译项目 8 | 9 | 1. 安装hiredis，解压文件中hiredis.tar（后续对源码进行了改动，文件中是改后的） 10 | 11 | ```shell 12 | tar -xvf hiredis.tar 13 | cd hiredis/ 14 | make 15 | make install # 权限不足加上sudo 16 | ``` 17 | 18 | 2. 删除之前的CMakeCache.txt 19 | 20 | ```shell 21 | cd ConnPool/ 22 | rm CMakeCache.txt 23 | ``` 24 | 25 | 3. 重新cmake和make 26 | 27 | ```shell 28 | cmake . 29 | make -j4 30 | ``` 31 | 32 | 4. 后续引入头文件SimConnPool.h即可使用，简单应用见tests文件 33 | 34 | ## 整体架构 35 | 1. RedisHelper：redis相关操作，创建一个连接时构造函数不做任何事，在connection函数时才真正建立一条连接，每条连接都包含一个指向连接池的指针，为了实现放回操作，基础实现依赖hiredis库中的redisCommand函数 36 | 2. ConnPool ：连接池模板，初始化时构造函数不做任何操作，在连接池connection时才执行init函数完成每一个连接的初始化，并且依次调用每条连接的connection函数 37 | 3. Singleton：单例模板，包装ConnPool类，变成单例对象 38 | 39 | 40 | ## 使用 41 | 42 | ```c++ 43 | static SimpleConnPool::redisPool* pool = SimpleConnPool::redisConnPoolMgr::GetInstance(); // 获取一个连接池单例对象，默认5个连接 44 | pool->connection("127.0.0.1", 6000); // 连接池内连接上redis，入参：ip、端口号、密码默认为空 45 | SimpleConnPool::redisPool::connPtr conn = pool->get(); // 取出一条连接 46 | // TODO 47 | conn->connBack(); // 放回连接 48 | 49 | ``` 50 | 51 | ## 分布式锁 52 | 53 | > 当多线程并发访问数据库中某个资源时，可能同一时间返回都取到了旧值，并且对旧值进行变更，这样会造成逻辑上的混淆。比如在电商场景，库存这个变量，当多个用户进行抢购的时候，首先判断库存然后库存减一，若不加锁，库存为1的时候，可能多个用户获取库存判断时都拿到了1，最后都进行库存减一，可能就出现负数了。 54 | 55 | 在分布式系统环境下，一个方法在同一时间只能被一个机器的一个线程执行 56 | 57 | 高可用的获取锁与释放锁 58 | 59 | 具备可重入特性（可理解为重新进入，由多于一个任务并发使用，而不必担心数据错误） 60 | 61 | 具备锁失效机制，即自动解锁，防止死锁 62 | 63 | 64 | 65 | 加锁： 66 | 67 | 实际是，对一个键进行赋值，借助set key val NX PX timeout 语句实现，NX表示若键存在返回nil，不存在则赋值，当多线程运行到lock时，只有第一个执行语句的线程可以跳出，继续执行，其余线程都需要阻塞在lock内部。 68 | 69 | 设置超时时间为了保证不会因为加锁线程挂掉而导致死锁的情况。 70 | 71 | ```c++ 72 | /* 73 | 加锁逻辑： 74 | 在不存在键时设置键 并同时设置超时时间 保证原子性 75 | set key value NX PX timeout 76 | 默认10秒 77 | 返回该线程拿到锁生成的值，后续解锁比较，不能因为挂机或网络原因解锁别的线程锁 78 | 分布式锁的键为：redis.lock 值为：当前时间戳 nsec 79 | */ 80 | std::string lock(uint64_t timeout = 30000) { 81 | while(1) { 82 | struct timespec time = {0, 0}; 83 | clock_gettime(CLOCK_REALTIME, &time); 84 | std::string uuid = std::to_string(time.tv_nsec); 85 | std::string cmd = "set redis.lock " + uuid + " NX PX " + std::to_string(timeout); 86 | std::string flag; 87 | RedisState sta; 88 | { 89 | MutexType::Lock lock(m_mutex); 90 | sta = execute(cmd, &flag); 91 | } 92 | if(sta == RedisState::M_REDIS_OK) { 93 | std::cout << "get redis.lock!" << std::endl; 94 | return uuid; 95 | } 96 | } 97 | } 98 | ``` 99 | 100 | 解锁： 101 | 102 | 需要取值、判断、删除三个操作，因此使用lua脚本来保证原子性，判断是为了保证不会删除其余线程所创建的锁。 103 | 104 | ```c++ 105 | /* 106 | 解锁逻辑： 107 | 获取锁，判断锁，删除锁 108 | 为了保证原子性，使用lua脚本来完成三个操作 109 | redis使用eval "xxxx" keys数量 key1 key2 num1 num2 110 | */ 111 | void unlock(const std::string& uuid) { 112 | std::string cmd = "eval \"if redis.call('get',KEYS[1]) == ARGV[1] then return redis.call('del',KEYS[1]) else return 0 end\" 1 redis.lock " + uuid; 113 | int flag; 114 | RedisState sta = executeLua(cmd.c_str(), &flag); 115 | if(sta == RedisState::M_REDIS_OK && flag > 0) { 116 | std::cout << "获取到锁并解锁" << std::endl; 117 | } 118 | else { 119 | std::cout << "未获取到锁 errstr: " << m_error_msg << std::endl; 120 | } 121 | return ; 122 | } 123 | ``` 124 | 125 | 126 | 127 | ## 总结 128 | 129 | 基于hiredis，只需要引入头文件即可使用，简单方便，复杂语句使用execute函数直接执行，但是需要根据redis客户端返回值，传入该函数第二个参数（set，get返回ok就传string，del返回1或0就传int） 130 | 131 | 为了可以执行lua脚本，对hiredis中源码进行了改动，原先是以空格来分割命令的，但是lua脚本需要return时肯定包含空格，需要更改分割规则，增加以双引号分割，详见（[hiredis中lua脚本调用_hiredis lua_suhiymof的博客-CSDN博客](https://blog.csdn.net/suhiymof/article/details/54847818)） 132 | 133 | ```c++ 134 | std::string cmd = "EVAL \"redis.call('SET', KEYS[1], ARGV[1]) local result = redis.call('get',KEYS[1]) return result\" 1 foo1 bar1";
