1、安装依赖
yum -y install lrzsz git gcc gcc-c++ lz4-devel
2、下载安装cmake（gflags-2.2.2对cmake版本有要求）
curl -O mv cmake-3.6.0-Linux-x86_64.tar.gz /opt/ cd /opt/ tar -xvzf cmake-3.6.0-Linux-x86_64.tar.gz yum remove cmake cat >>/etc/profile <<EOF export PATH=\$PATH:/opt/cmake-3.6.0-Linux-x86_64/bin EOF source /etc/profile
3、安装依赖gflags
wget 我这里是windows下载好上传的文件包 tar -xvzf gflags-2.2.2.tar.gz cd gflags-2.2.2/ mkdir build cd build/ cmake -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DINSTALL_HEADERS=ON -DINSTALL_SHARED_LIBS=ON -DINSTALL_STATIC_LIBS=ON .. make make install 添加lib信息 cat >>/etc/profile <<EOF export LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/local/lib EOF source /etc/profile
4、下载安装rocksdb
wget https://github.com/facebook/rocksdb/archive/v6.4.6.tar.gz 我这里用的是windows下载的包 tar -xvzf rocksdb-6.4.6.tar.gz cd rocksdb-6.4.6/ mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/usr/local/rocksdb .. make make install cat >>/etc/profile <<EOF export CPLUS_INCLUDE_PATH=\$CPLUS_INCLUDE_PATH:/usr/local/rocksdb/include/ export LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/usr/local/rocksdb/lib64/ export LIBRARY_PATH=\$LIBRARY_PATH:/usr/local/rocksdb/lib64/ EOF source /etc/profile
5、ldb工具进行测试
cd rocksdb-6.4.6/build/tools/ [root@es1 tools]# ./ldb -help ldb - RocksDB Tool commands MUST specify --db=<full_path_to_db_directory> when necessary The following optional parameters control if keys/values are input/output as hex or as plain strings: --key_hex : Keys are input/output as hex --value_hex : Values are input/output as hex --hex : Both keys and values are input/output as hex The following optional parameters control the database internals: --column_family=<string> : name of the column family to operate on. default: default column family --ttl with 'put','get','scan','dump','query','batchput' : DB supports ttl and value is internally timestamp-suffixed --try_load_options : Try to load option file from DB. --ignore_unknown_options : Ignore unknown options when loading option file. --bloom_bits=<int,e.g.:14> --fix_prefix_len=<int,e.g.:14> --compression_type=<no|snappy|zlib|bzip2|lz4|lz4hc|xpress|zstd> --compression_max_dict_bytes=<int,e.g.:16384> --block_size=<block_size_in_bytes> --auto_compaction=<true|false> --db_write_buffer_size=<int,e.g.:16777216> --write_buffer_size=<int,e.g.:4194304> --file_size=<int,e.g.:2097152> Data Access Commands: put <key> <value> [--ttl] get <key> [--ttl] batchput <key> <value> [<key> <value>] [..] [--ttl] scan [--from] [--to] [--ttl] [--timestamp] [--max_keys=<N>q] [--start_time=<N>:- is inclusive] [--end_time=<N>:- is exclusive] [--no_value] delete <key> deleterange <begin key> <end key> query [--ttl] Starts a REPL shell.
