python下redis的基本操作:
1. 基本操作:
>>> import redis >>> print redis.__file__ /usr/local/lib/python2.7/dist-packages/redis/__init__.pyc >>> redisClient = redis.Redis(host='127.0.0.1', port=6379, db=0) >>> info = redisClient.info() >>> for key in info: ... print "%s:%s" %(key, info[key]) ... aof_rewrite_in_progress:0 total_connections_received:8 run_id:0a62a8d1e52971400a930715b8f621e05a26ba8b rejected_connections:0 redis_build_id:cee0f9a49c3c27aa used_memory_peak_human:578.38K pubsub_patterns:0 redis_mode:standalone connected_slaves:0 db2:{'keys': 179, 'expires': 0, 'avg_ttl': 0} uptime_in_days:0 multiplexing_api:epoll lru_clock:9571444 redis_version:2.8.13 redis_git_sha1:0 sync_partial_ok:0 gcc_version:4.9.1 connected_clients:2 keyspace_misses:4 used_memory:590392 tcp_port:6379 master_repl_offset:0 used_cpu_user_children:0.0 repl_backlog_first_byte_offset:0 rdb_current_bgsave_time_sec:-1 pubsub_channels:0 used_cpu_user:1.96 used_memory_lua:33792 instantaneous_ops_per_sec:0 rdb_last_save_time:1435633828 total_commands_processed:141 aof_last_write_status:ok role:master aof_rewrite_scheduled:0 sync_partial_err:0 used_memory_rss:7311360 hz:10 sync_full:0 aof_enabled:0 config_file:/etc/redis/redis.conf used_cpu_sys:3.1 rdb_last_bgsave_status:ok latest_fork_usec:135 aof_last_bgrewrite_status:ok db4:{'keys': 7, 'expires': 6, 'avg_ttl': 721067416} aof_last_rewrite_time_sec:-1 used_memory_human:576.55K loading:0 blocked_clients:0 process_id:2006 db0:{'keys': 3, 'expires': 0, 'avg_ttl': 0} repl_backlog_histlen:0 client_biggest_input_buf:0 aof_current_rewrite_time_sec:-1 arch_bits:64 repl_backlog_active:0 mem_fragmentation_ratio:12.38 rdb_last_bgsave_time_sec:0 expired_keys:0 used_cpu_sys_children:0.01 evicted_keys:0 rdb_bgsave_in_progress:0 repl_backlog_size:1048576 client_longest_output_list:0 mem_allocator:jemalloc-3.6.0 used_memory_peak:592256 db3:{'keys': 1, 'expires': 1, 'avg_ttl': 686672452} uptime_in_seconds:9532 rdb_changes_since_last_save:0 redis_git_dirty:0 os:Linux 3.16.0-37-generic x86_64 keyspace_hits:43 >>>
