linux版本下memcached+libmemcached

1、下载安装libmemcached $ wget http://launchpad.net/libmemcached/1.0/0.44/+download/libmemcached-0.44.tar.gz $ tar xvzf libmemcached-0.44tar.gz $ cd libmemcached-0.44 $ ./configure --with-memcached $ make $ sudo make install libmemcached 默认安装在/usr/local/,头文件安装在/usr/local/include/libmemcachde/,动态库默认安装在/usr/local/lib/下。 2. 编写文件 MemCachedClient.h 输入下面内容： #ifndef MEMCACHEDCLIENT #define MEMCACHEDCLIENT #include <libmemcached/memcached.h> #include<iostream> #include<string> #include<time.h> using std::string; using std::cout; using std::endl; class MemCachedClient { public: ~MemCachedClient() { memcached_free(memc); }; MemCachedClient() { memcached_return rc; memcached_server_st *server = NULL; memc = memcached_create(NULL); server =memcached_server_list_append(server, "192.168.45.144", 11211, &rc); rc=memcached_server_push(memc,server); if (MEMCACHED_SUCCESS != rc) { cout <<"memcached_server_push failed! rc: " << rc << endl; } memcached_server_list_free(server); }; int Insert(const char* key, const char* value,time_t expiration = 3) { if (NULL == key || NULL == value) { return -1; } uint32_t flags = 0; memcached_return rc; rc = memcached_set(memc, key, strlen(key),value, strlen(value), expiration, flags); // insert ok if (MEMCACHED_SUCCESS == rc) { return 1; } else { return 0; } }; string Get(const char* key) { if (NULL == key) { return ""; } uint32_t flags = 0; memcached_return rc; size_t value_length; char* value = memcached_get(memc, key, strlen(key), &value_length, &flags, &rc); // get ok if(rc == MEMCACHED_SUCCESS) { return value; } return ""; }; private: memcached_st* memc; }; #endif 再编写 test.cc 文件 #include<iostream> #include"MemCachedClient.h" using std::cout; using std::endl; int main() { MemCachedClient mc; mc.Insert("kingcat","value123"); cout << mc.Get("kingcat") << endl; return 1; }; 3. 用g++编译: g++ test.cc -o test -lmemcached (一定别把库链接忘了否则编译不通过) 4. 执行./test 最后可能会报错，提示./testmemcached: error while loading shared libraries: libmemcached.so.10: cannot open shared object file: No such file or directory 解决方法： 1、cp /usr/local/lib/libmemcached.so.5 /usr/lib/ 2、 ln /usr/local/lib/libmemcached.so.5 /usr/lib/libmemcached.so.5 即可
